Preventing falls in older multifocal glasses wearers by providing single-lens distance glasses: the protocol for the VISIBLE randomised controlled trial

Background

Recent research has shown that wearing multifocal glasses increases the risk of trips and falls in older people. The aim of this study is to determine whether the provision of single-lens distance glasses to older multifocal glasses wearers, with recommendations for wearing them for walking and outdoor activities, can prevent falls. We will also measure the effect of the intervention on health status, lifestyle activities and fear of falling, as well as the extent of adherence to the program.

Methods/Design

Approximately 580 older people who are regular wearers of multifocal glasses people will be recruited. Participants will be randomly allocated to either an intervention group (provision of single lens glasses, with counselling and advice about appropriate use) or a control group (usual care). The primary outcome measure will be falls (measured with 13 monthly calendars). Secondary measures will be quality of life, falls efficacy, physical activity levels and adverse events.

Discussions

The study will determine the impact of providing single-lens glasses, with advice about appropriate use, on preventing falls in older regular wearers of multifocal glasses. This pragmatic intervention, if found to be effective, will guide practitioners with regard to recommending appropriate glasses for minimising the risk of falls in older people.

Trial Registration

The protocol for this study was registered with the Clinical Trials.gov Protocol Registration System on June 7^th 2006 (#350855).     

How Should Nations Measure the Quality of End‐of‐Life Care for Older Adults? Recommendations for an International Minimum Data Set

Nations face numerous challenges in providing high-quality end-of-life care for their citizens, and an aging population that has a prolonged trajectory of decline and substantial needs for care magnifies these challenges. As nations begin to address these challenges, it will be essential to determine whether their responses are effective, but current national data collection efforts are sporadic, and data are often collected only for patients who receive care through certain funding programs or provider organizations or in selected sites of care. Therefore, governments do not know whether their citizens are receiving adequate care, whether current programs are improving care, or how their outcomes compare with those of other countries. This article describes the importance of developing national minimum data sets that can be used to assess the quality of end-of-life care that older adults receive and recommends key variables that these data sets should include.     

A comparison of symptom prevalence in far advanced cancer, AIDS, heart disease, chronic obstructive pulmonary disease and renal disease

Little attention has been paid to the symptom management needs of patients with life-threatening diseases other than cancer. In this study, we aimed to determine to what extent patients with progressive chronic diseases have similar symptom profiles. A systematic search of medical databases (MEDLINE, EMBASE, and PsycINFO) and textbooks identified 64 original studies reporting the prevalence of 11 common symptoms among end-stage patients with cancer, acquired immunodeficiency syndrome (AIDS), heart disease, chronic obstructive pulmonary disease, or renal disease. Analyzing the data in a comparative table (a grid), we found that the prevalence of the 11 symptoms was often widely but homogeneously spread across the five diseases. Three symptoms-pain, breathlessness, and fatigue-were found among more than 50% of patients, for all five diseases. There appears to be a common pathway toward death for malignant and nonmalignant diseases. The designs of symptom prevalence studies need to be improved because of methodological disparities in symptom assessment and designs.     

Early goal-directed therapy: a UK perspective

The surviving sepsis campaign developed guidelines in 2003 that were designed to increase physician awareness of sepsis and to develop a series of recommendations for the management of the patient with sepsis. The guidelines had the support of 11 international professional organisations across a variety of specialties, and advocate aggressive, early goal-oriented resuscitation in appropriate patients.     

Two new patients with Curry-Jones syndrome with trichoblastoma and medulloblastoma suggest an etiologic role of the sonic hedgehog-patched-GLI pathway

Curry-Jones syndrome (OMIM #601707) is a rare multiple malformation disorder of unknown etiology, associated with brain and skull abnormalities, polysyndactyly, and defects of the eyes, skin and gastrointestinal tract. We report on two new cases of Curry-Jones syndrome with previously unreported features, including benign and malignant neoplasms. The first patient had typical features of Curry-Jones syndrome as well as multiple intra-abdominal smooth muscle hamartomas and trichoblastoma of the skin. The second patient was born with occipital meningoceles and developed a desmoplastic medulloblastoma. Routine lymphocyte karyotype, GLI3 gene analysis and Patched (PTCH) gene analysis on both patients and chromosome microarray analysis on the first patient were normal. We review the previously reported cases of Curry-Jones syndrome and compare our patients' findings. In view of the association of trichoblastoma with basal cell carcinoma and desmoplastic medulloblastoma with nevoid basal cell carcinoma syndrome (NBCCS) and PTCH mutations, we hypothesize that Curry-Jones syndrome is caused by malfunction of an element in the sonic hedgehog pathway.
