Effectiveness of a home-based cognitive behavioral program to manage concerns about falls in community-dwelling, frail older people: results of a randomized controlled trial

Background: Concerns about falls are common among older people. These concerns, also referred to as fear of falling, can have serious physical and psychosocial consequences, such as functional decline, increased risk of falls, activity restriction, and lower social participation. Although cognitive behavioral group programs to reduce concerns about falls are available, no home-based approaches for older people with health problems, who may not be able to attend such group programs are available yet. The aim of this study was to assess the effectiveness of a home-based cognitive behavioral program on concerns about falls, in frail, older people living in the community. Methods: In a randomized controlled trial in the Netherlands, 389 people aged 70 years and older, in fair or poor perceived health, who reported at least some concerns about falls and related activity avoidance were allocated to a control (n = 195) or intervention group (n = 194). The intervention was a home-based, cognitive behavioral program consisting of seven sessions including three home visits and four telephone contacts. The program aims to instill adaptive and realistic views about fall risks via cognitive restructuring and to increase activity and safe behavior using goal setting and action planning and was facilitated by community nurses. Control group participants received usual care. Outcomes at 5 and 12 months follow-up were concerns about falls, activity avoidance due to concerns about falls, disability and falls. Results: At 12 months, the intervention group showed significant lower levels of concerns about falls compared to the control group. Furthermore, significant reductions in activity avoidance, disability and indoor falls were identified in the intervention group compared with the control group. Effect sizes were small to medium. No significant difference in total number of falls was noted between the groups. Conclusions: The home-based, cognitive behavioral program significantly reduces concerns about falls, related activity avoidance, disability and indoor falls in community-living, frail older people. The program may prolong independent living and provides an alternative for those people who are not able or willing to attend group programs

Non-aqueous Isorefractive Pickering Emulsions

Non-aqueous Pickering emulsions of 16–240 μm diameter have been prepared using diblock copolymer worms with ethylene glycol as the droplet phase and an n-alkane as the continuous phase. Initial studies using n-dodecane resulted in stable emulsions that were significantly less turbid than conventional water-in-oil emulsions. This is attributed to the rather similar refractive indices of the latter two phases. By utilizing n-tetradecane as an alternative oil that almost precisely matches the refractive index of ethylene glycol, almost isorefractive ethylene glycol-in-n-tetradecane Pickering emulsions can be prepared. The droplet diameter and transparency of such emulsions can be systematically varied by adjusting the worm copolymer concentration

Eculizumab as rescue therapy for atypical hemolytic uremic syndrome with normal platelet count

Item does not contain fulltextBACKGROUND: Atypical hemolytic uremic syndrome (aHUS) in childhood is a rare disease with frequent progression to end-stage renal disease and a high recurrence after kidney transplantation. Eculizumab, a humanized monoclonal antibody that binds to complement protein C5, may be beneficial in the treatment of aHUS. CASE-DIAGNOSIS/TREATMENT: A 6-year-old girl developed aHUS with only slightly elevated C3d (4.4%), no mutations in complement factors, and no antibodies against factor H. Plasma exchange treatment was successful initially, until aHUS recurred. After reinitiating plasma exchange, normalization of the platelet count and improvement of hemolysis occurred, but renal function worsened. Renal function then improved dramatically promptly after the switch to eculizumab. CONCLUSIONS: This case demonstrates that platelet count is not always a reliable marker for improvement of aHUS and that eculizumab can prevent dialysis in plasma-resistant aHUS patients.1 juli 201

Estimating treatment effects for individual patients based on the results of randomised clinical trials

Objectives To predict treatment effects for individual patients based on data from randomised trials, taking rosuvastatin treatment in the primary prevention of cardiovascular disease as an example, and to evaluate the net benefit of making treatment decisions for individual patients based on a predicted absolute treatment effect
