- We investigated the effects of ionizing radiation on microvessel structure and complexity in the hippocampus. We also assessed neurogenesis and the neurovascular niche. Postnatal day 14 male C57BL/6 mice received a single dose of 8Gy to the whole brain and were killed 6 hours, 1 week, 7 weeks, or 1 year later. Irradiation decreased the total number of microvessels and branching points from 1 week onwards and decreased the total microvessel area 1 and 7 weeks after irradiation. After an initial increase in vascular parameter densities, concomitant with reduced growth of the hippocampus, the densities normalized with time, presumably adapting to the needs of the surrounding nonvascular tissue. Irradiation decreased the number of neural stem and progenitor cells in the hippocampus. The relative loss increased with time, resulting in almost completely ablated neurogenesis (DCX(+) cells) 1 year after irradiation (77% decreased 1 week, 86% decreased 7 weeks, and 98% decreased 1 year after irradiation compared with controls). After irradiation, the distance between undifferentiated stem cells and microvessels was unaffected, and very few dying endothelial cells were detected. Taken together, these results indicate that the vasculature adjusts to the surrounding neural and glial tissue after irradiation, not vice-versa.Journal of Cerebral Blood Flow & Metabolism advance online publication, 13 March 2013; doi:10.1038/jcbfm.2013.34.

- BACKGROUND: As they age, older persons prefer to continue to live in their own homes. Sensors in the environment and/or bodily worn systems that monitor people might contribute to an increased sense of safety and security at home, but also raise concerns about the loss of privacy by surveillance. Little is known about how older persons, living at home independently and stating good health, perceive monitoring technology in terms of personal privacy.OBJECTIVE: to identify and describe how older persons, perceive monitoring technology in terms of personal privacy.METHOD: A qualitative study based on five focus group interviews was used. Concepts of "freedom" and "surveillance" were used as content areas in the data analysis.RESULTS: The results comprised three categories of ambivalence; "independence vs. security", "privacy vs. intrusion", and "in the best interest of me vs. in the best interest of others". These three categories merged into the overarching theme "maintaining a sense of self" which illustrates a desire to maintain control of one's life as long as possible.CONCLUSIONS: Older persons generally have positive feelings and attitudes toward technology and strive to maintaining a sense of self as long as possible, by having control. They stated high value to privacy, but valued being watched over if it ensured security. To feel good and bad about monitoring technologies, rather than good or does not necessarily lead to feelings of conflict.

- (PERS) alarms have been used in Sweden since 1974 to enable older people to age safely at home. Despite this long use, we found no studies describing independent older users’ opinions of these devices.Aim Our aim was to describe how people living in Swedish independent senior housing perceive the alarms and to highlight their wishes for further developments and innovations.Methods We conducted five focus group interviews with residents of senior housing who used or had used a PERS alarm and analysed the data qualitatively for latent content.Results The data analysis revealed five themes in participants’ opinions and feelings about the PERS alarms: (i) safety, (ii) anxiety, (iii) satisfaction, (iv) being informed, and (v) older persons as active innovators.Conclusion The 40-year-old Swedish PERS used in senior housing seems to limit rather than liberate users in their daily lives and cause feelings of insecurity rather than security. Older Swedish people require a more personalized alarm with a built-in positioning system that would allow them a greater range of movement beyond their homes.

- To investigate the effects of cranial irradiation on the neurovascular niche in the young brain. Disruption of this niche has previously been observed in the adult rat brain after irradiation.We subjected postnatal day 14 (P14) mice to a single dose of 8 Gy whole brain irradiation and measured the distance between microvessels and either neural progenitor cells (doublecortin-positive, DCX(+)) or proliferating cells (Ki-67(+)) in the dorsal hippocampal subgranular zone (SGZ) 6 hours, 1 week and 7 weeks post-irradiation. In addition, pericyte coverage of microvessels in the SGZ was measured.DCX(+) and Ki-67(+) cells were located closer to microvessels in the adult brain compared to young, still growing brains, constituting new information on normal development. We found an increased distance between microvessels and DCX(+) cells 6 h post-irradiation and between microvessels and Ki-67(+) cells 1 week post-irradiation. Furthermore, pericyte coverage was transiently decreased by 17% 6 h post-irradiation.The hippocampal neurovascular niche in the young, growing brain is transiently disrupted by irradiation. It remains to be elucidated what role these transient changes play in the apparently permanent ablation of hippocampal neurogenesis previously demonstrated in the same model.

Trygghet - på vems villkor? Uppfattningar om och erfarenheter av trygghet hos äldre personer med behov av omsorg
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Syftet med avhandlingen var att bidra till ökad förståelse av hur äldre personer med skiftande omsorgsbehov uppfattade och erfor trygghet, i ordinärt och särskilt boende.Avhandlingens två första studier baserades på material från fokusgruppintervjuer med totalt 45 äldre personer boende i seniorboende. Intervjuerna analyserades med kvalitativ innehållsanalys (I, II). Den tredje studien bestod av en sekundäranalys av en brukarenkät till 350 äldre personer i ordinärt boende med hemtjänst och 145 äldre personer i särskilt boende. Materialet bearbetades med deskriptiv och analytisk statistik (III). I den fjärde studien följdes tre äldre personer, genom djupintervjuer och observationer under 12-16 veckor, vid flytt till särskilt boende och den första tiden på särskilt boende. Även detta material analyserades med kvalitativ innehållsanalys (IV).Avhandlingens resultat visar bland annat att de trygghetslarm som de äldre hade erfarenhet av uppfattades som begränsande då larmets korta räckvidd gav orsak till minskad frihet, otrygghet, oro och rädsla (I). Övervakningsteknik, där den äldres person och position övervakas i större omfattning, ansågs inte som något problem att använda när omsorgsinsatserna ökade, så länge detta medförde ökad trygghet (II). Upplevd hälsa, relationstrygghet samt kunskap och kontroll var faktorer som var positivt relaterade till hur äldre personer med äldreomsorg uppfattade och erfor trygghet i vardagen, både i ordinärt och i särskilt boende (III). Flytt till särskilt boende som innebar att stegvis överlämna sitt livoch sin kontroll till omsorgspersonalen, ledde till en känsla av ökad säkerhet för de äldre personerna men inte nödvändigtvis till känsla av trygghet (IV).Resultatet tolkades i förhållande till Antonovskys salutogena teori där de tre koncepten meningsfullhet, hanterbarhet och begriplighet, tillsammans utgör grunden för känsla av sammanhang (KASAM).Sammanfattningsvis uppfattade och erfor äldre personer trygghet som så meningsfull att de kunde tänka sig att ge avkall på en del av sin frihet, integritet, självständighet och självbevarande för att uppnå den. De äldre personerna beskrev att resurser som personal och trygghetslarm stärkte tryggheten, men att hanterbarheten av dessa resurser kan stärkas ytterligare, i både ordinärt boende och särskilt boende. Resultaten visaratt äldre personers begriplighet av vardagen relaterar positivt till uppfattningar och erfarenheter av trygghet. Äldre personer saknar dock begriplighet avseende exempelvis trygghetslarm och nya rutiner, vilket får negativ inverkan på deras trygghet. Äldre personer bör ges större utrymme att själva beskriva trygghet utifrån sina unika villkor. För att stärka trygghet på äldre personers villkor, oavsett deras omsorgsbehov, bör således hanterbarheten, men framförallt begripligheten, stärkas.

What do old persons think about the first generation of security systems?
- 2010
-
Ingår i: Gerontechnology. ; , s. 266-
-
Konferensbidrag (refereegranskat)abstract
- Background: Older people don’t always know what new technology can do, so it may be difficult to outline needs, constraints and specifications. The marketing functions, the demand for technology and the supply of technology therefore needs to be strengthened. Though many older persons rely on various assistive technologies in their daily life and therefore represent a large group of consumers with the experience of existing technology, their influence over the technology they have access to as well as their involvement in design processes and product development is also very small. Aim: This study has two objectives; the first is to describe older people's experiences about using their existing security systems. The second is to highlight and make the older peoples thoughts and wishes available in further development and innovations of the second generation of context-aware distributed assistive systems, like wireless sensor network (WSN). Method: Five focus group interviews including 7-10 persons were conducted. Totally, 45 community living men and females (75-85 years of age) without home help and who had not been diagnosed with dementia participated. Data were analyzed by content analysis and selected into six themes. Result: The preliminary results show that the old persons feel dissatisfied as well as unsafe with their present security alarms. They feel limited when security alarms are only fit in their own apartment, and therefore they feel insecure and restricted in their freedom. They are experiencing a need to compensate the lack of safety with other products or persons. They also report that they have received poor information, which affect their sense of security. The elderly seem to have specific needs with their alarm systems that might be useful in further development of context-aware distributed assistive systems as well as ethical issues also has arisen in the discussion about enlarged alarm systems.
