Integration of nursing services provided to patients with heart failure living at home: A longitudinal ethnographic study.

Aims And Objectives: This study aimed to (1) describe the development of integrated services between hospital-based heart failure nursing services and municipally located home care nurses' services and (2) identify the benefits of this collaboration for the development of home care nursing services.

Background: Governments have called for better integration of healthcare services to respond to demographic ageing. Clinical pathways have been used to enhance integration and assure continuity between primary and secondary care.

Community-based dementia care re-defined: Lessons from Iceland.

Studies of families caring for persons with dementia living at home often reflect feelings of being forgotten and abandoned by the authorities to shoulder the responsibility for care-giving. This has increased interest in how formal services can better support these families. This article analyses how health and social care professionals envision the needs of families of persons with dementia living in the community.

Maedi-visna virus persistence: Antigenic variation and latency.

Maedi-visna virus (MVV), a lentivirus of sheep, shares with other lentiviruses the ability to establish a lifelong infection. In this study five sheep were infected intravenously with MVV and housed together with a number of uninfected sheep for natural transmission. All virus isolates from ten sheep that had been infected naturally had multiple mutations in the principal neutralization domain in Env and were antigenic variants, while three of four isolates from the carrier sheep had identical sequences to the infecting strain and were not antigenic variants.

Vaccination delays Maedi-Visna lentivirus infection in a naturally-infected sheep flock.

Background: The Maedi-Visna (MV) lentivirus causes two slowly progressive eventually fatal diseases of sheep, Maedi, a progressive interstitial pneumonia, and Visna, a progressive demyelinating disease of the central nervous system. Other lentiviruses also cause fatal slow infections in their natural hosts, e.g.

Activation of maternal Epstein-Barr virus infection and risk of acute leukemia in the offspring.

After identifying an association between maternal Epstein-Barr virus (EBV) reactivation and acute lymphoblastic leukemia (ALL), the authors analyzed a nested case-control study within Finnish and Icelandic maternity cohorts with 7 million years of follow-up to confirm EBV's role in ALL. Offspring of 550,000 mothers were followed up to age 15 years during 1975-1997 by national cancer registries to identify leukemia cases. Mothers of cases and three quarters of matched mothers of controls were identified by national population registers.

Associations between three types of maternal bacterial infection and risk of leukemia in the offspring.

A case-control study was nested within two maternity cohorts with a total of 7 million years of follow-up for assessment of the role of bacterial infections in childhood leukemia. Offspring of 550,000 mothers in Finland and Iceland were combined to form a joint cohort that was followed for cancer up to age 15 years during 1975-1997 through national cancer registries. For each index mother-case pair, three or four matched control mother-control pairs were identified from population registers.

Maternal herpesvirus infections and risk of acute lymphoblastic leukemia in the offspring.

A critical role for infection in the etiology of childhood leukemia has repeatedly been suggested. The authors undertook a case-control study nested within national maternity cohorts with altogether 7 million years of follow-up to assess the relative role of three maternal herpesvirus infections in childhood acute lymphoblastic leukemia (ALL). Offspring of 550,000 mothers in Finland and Iceland formed the joint study cohort that was followed up for cancer in the offspring before age 15 years during 1975-1997 through national cancer registries.
