Quality of life among older people in Sweden receiving help from informal and/or formal helpers at home or in special accommodation

Abstract: The present study describes and compares quality of life (QoL) and factors which predict QoL among people aged 75 years and over who receive help with activities of daily living (ADLs) from formal and/or informal helpers. The subjects were living at home or in special accommodation in Sweden. A postal questionnaire was sent to a randomly selected and age-stratified sample of 8500 people. The response rate was 52.8% (n = 4337), and 1247 people [mean age (+/- SD) = 86.4 +/- 5.9 years] received help and indicated who helped them with ADLs. The findings suggest that a greater age, being a woman, being a widow/widower, a higher number of health-related complaints, needing more help with ADLs and a lower QoL were found among those receiving help in special accommodation in comparison with those receiving help at home. The extent of help was highest among those receiving help in special accommodation. Having help with ADLs every day at home indicated having help from both informal and formal helpers, while respondents receiving help from only informal or only formal helpers received the smallest amount of help with ADLs. A need for greater help with ADLs, and a higher number of self-reported diseases and complaints determined low QoL, whilst a social network (contact with more than three people) and a greater age determined high QoL. However, who the helpers were did not have a significant influence on QoL; it was the extent of help with ADLs that influenced QoL negatively and the density of the social network that influenced QoL positively.

Sequential Broadening of CTL Responses in Early HIV-1 Infection Is Associated with Viral Escape

Abstract: Author(s): Karlsson, Annika C; Iversen, Astrid KN; Chapman, Joan M; de Oliviera, Tulio; Spotts, Gerald; McMichael, Andrew J; Davenport, Miles P; Hecht, Frederick M; Nixon, Douglas F | Abstract: BackgroundAntigen-specific CTL responses are thought to play a central role in containment of HIV-1 infection, but no consistent correlation has been found between the magnitude and/or breadth of response and viral load changes during disease progression.Methods and findingsWe undertook a detailed investigation of longitudinal CTL responses and HIV-1 evolution beginning with primary infection in 11 untreated HLA-A2 positive individuals. A subset of patients developed broad responses, which selected for consensus B epitope variants in Gag, Pol, and Nef, suggesting CTL-induced adaptation of HIV-1 at the population level. The patients who developed viral escape mutations and broad autologous CTL responses over time had a significantly higher increase in viral load during the first year of infection compared to those who did not develop viral escape mutations.ConclusionsA continuous dynamic development of CTL responses was associated with viral escape from temporarily effective immune responses. Our results suggest that broad CTL responses often represent footprints left by viral CTL escape rather than effective immune control, and help explain earlier findings that fail to show an association between breadth of CTL responses and viral load. Our results also demonstrate that CTL pressures help to maintain certain elements of consensus viral sequence, which likely represent viral escape from common HLA-restricted CTL responses. The ability of HIV to evolve to escape CTL responses restricted by a common HLA type highlights the challenges posed to development of an effective CTL-based vaccine.

A randomized controlled trial evaluating the effects of online rehabilitative intervention for adult hearing-aid users.

Abstract: Objective: Previous research shows that the internet can be used in the rehabilitation of hearing aid users. By further developing the online program, it might be possible to foster behavioral chan ...
