'Living together on one's own': Cohousing for older people - an example from Denmark and The Netherlands

‘Living together on one’s own’ is the seemingly contradictory expression of the National Association of Housing Communities for Elderly People (LVGO) in The Netherlands which in fact captures the essence of cohousing. Cohousing is a novel kind of neighbourhood, housing a novel form of intentional community, which began to take shape in Denmark in the early to mid-1960s and, independently, in The Netherlands a few years later. The inventors of cohousing wanted to live in a much more communal or community-oriented neighbourhood than was usual, but they wanted to do so without sacrificing the privacy of individual families or households and their dwellings. Could they have their cake and eat it too? It would seem so. What is cohousing for older people (op-cohousing)? Op-cohousing is essentially no different, except for the differences in outlook or expectations, experience, interests and abilities that a particular, exclusively older, group of people have brought to this housing type. I discuss and analyse several communities in both countries.

Paternal age as a risk factor for psychosis and schizophrenia: Findings from Denmark, Sweden and Australia

The offspringof older fathers have an increased risk of various disorders that may be due to the accumulation of DNA mutations during spermatogenesis. Previous studies have suggested increased paternal age may be a risk factor for schizophrenia. The aim of the current study was to examine paternal age as a risk factor for schizophrenia andror psychosis. We used data from three sources: a population-based cohort studyŽDenmark., and two case-control studiesŽSweden and Australia.. In the Danish and Australian studies, we examined both psychosis and schizophrenia. In the Swedish study we examined psychosis only. After controllingfor the effect of maternal age, increased paternal age was significantly associated with increased risk of both psychosis and schizophrenia in the Danish study and of psychosis in the Swedish study. The Australian study found no association between paternal age and risk of psychosis or schizophrenia. In all three studies the relationship between paternal age and risk of disorder in the offspring was AUB-shaped. In addition to an increased risk for the offspringof older father Ž)35 years., there was a non-significant increase for the offspringof fathers aged less than 20 years. The possible role of paternally derived DNA mutations andror other psychosocial factors associated with older paternal age warrants further research. The ‘U’-shaped relationship suggests that factors other than DNA mutations may warrant consideration in this research. The Stanley Foundation supported this project.

Defective NF-kappaB Activation in Response to LPS in Type 1 Diabetes Dendritic Cells

Dendritic cells (DC) are the potent antigen presenting cells which modulate T cell responses to self or non-self antigens. DC play a significant role in the pathogenesis of autoimmune diseases, inflammation and infection, but also in the maintenance of tolerance. NF-kappaB, particularly RelB is a crucial pathway for myeloid DC differentiation and functional maturation. While the current paradigm is that mature, nuclear RelB+ DC prime T cells for immunity/autoimmunity and immature DC for tolerance, RelB-deficient mice paradoxically develop generalised systemic autoimmune inflammatory disease with myelopoiesis and splenomegaly. Previous studies suggested abnormal DC differentiation in healthy relatives of type 1 diabetes (t1dm) patients. Therefore, we compared NF- kB activation in monocyte-derived DC from t1dm and non-t1dm controls in response to LPS. While resting DC appeared normal, DC from 6 out of 7 t1dm patients but no t2dm or rheumatoid arthritis patients failed to translocate NF- kB subunits to the nucleus in response to LPS, along with a failure to up-regulate expression of cell surface CD40 and MHC class I. NF- kB subunit mRNA increased normally in t1dm DC after LPS. Both the classical or non-canonical NF- kB pathways were affected as both TNF-a and CD40 stimulation led to a similarly abnormal NF- kB response. In contrast, expression of phosphorylated p38 MAPK and pro-inflammatory cytokine production was intact. These abnormalities in NF- kB activation appear to be generally and specifically applicable at a post-translational level in t1dm, and have the capacity to profoundly influence immunoregulation in affected individuals.

Isolation of Lautropia mirabilis from sputa of a cystic fibrosis patient

An aggregate-forming coccus, isolated twice as the predominant microorganism in sputa from a cystic fibrosis patient on consecutive days, was shown to belong to the species Lautropia mirabilis on the bases of similarities of 16S rRNA gene sequences and phenotype. These isolates of L. mirabilis appear to be the first reported from a patient with cystic fibrosis and outside of Denmark.

Predicting discharge outcomes for stroke patients in Australia

Objective: This study aimed to describe discharge outcomes and explore their correlates for patients rehabilitated after stroke at an Australian hospital from 1993 to 1998. Design: Data on length of stay, discharge functional status, and discharge destination were retrospectively obtained from medical records. Patients' actual rehabilitation length of stay was compared with the Australian National Sub-Acute and Non-Acute Patient predicted length of stay. The change in length of stay over the 5-yr period from 1993 to 1998 was documented. Results: Patients' mean converted motor FIMTM scores improved from 53.1 at admission to 74.1 at discharge. Lower admission-converted motor FIM scores were related to longer length of stay, lower discharge-converted motor FIM scores, and the need for a change in living situation on discharge. Conclusion: The results of this study provide Australian data on discharge outcomes after stroke to assist in the planning and delivery of appropriate interventions to individual patients during rehabilitation.
