Diminished mental- and physical function and lack of social support are associated with shorter survival in community dwelling older persons of Botswana
<p>Abstract</p> <p>Background</p> <p>Mortality rates for older persons in Botswana have been unavailable and little is known of predictors of mortality in old age. This study may serve as a precursor for more detailed assessments.</p> <p>The objective was to assess diminished function and lack of social support as indicators of short term risk of death.</p> <p>Methods</p> <p>A national population based prospective survey was undertaken in Botswana; twelve rural areas and three urban centers were included.</p> <p>372 community-dwelling persons aged sixty years and over, were included; 265 were followed-up. Sixteen subjects were deceased at follow-up.</p> <p>Subjects were interviewed and clinically assessed at home. Measures of cognitive function, depression and physical function and sociodemographic information were collected. Subjects were followed-up at average 6.8 months after baseline.</p> <p>Results</p> <p>Overall mortality rate was 10.9 per 100 person years. Age-adjusted odds ratios (OR) for death during follow-up were; 4.2 (CI 1.4â12.5) and 3.6 (CI 1.0â12.7) for those with diminished physical- and cognitive function, respectively.</p> <p>Indicators of limited social support; household with only 1 or 2 persons and eating alone, yielded age adjusted ORs of 4.3 (CI 1.5â12.5) and 6.7 (CI 2.2â20), respectively, for death during follow-up.</p> <p>Conclusion</p> <p>Older community dwelling persons with diminished cognitive- or physical function, solitary daily meals and living in a small household have a significantly increased risk of rapid deterioration and death.</p> <p>Health policy should include measures to strengthen informal support and expand formal service provisions to older persons with poor function and limited social networks in order to prevent premature deaths.</p

Practice Inquiry: Clinical Uncertainty as a Focus for Small-Group Learning and Practice Improvement
PROBLEM: Many primary care physicians in nonacademic settings lack a collegial forum for engaging the clinical uncertainties inherent in their work. PROGRAM DESCRIPTION: âPractice Inquiryâ is proposed as a set of small-group, practice-based learning and improvement (PBLI) methods designed to help clinicians better manage case-based clinical uncertainty. Clinicians meet regularly at their offices/clinics to present dilemma cases, share clinical experience, review evidence for blending with experience, and draw implications for practice improvement. From 2001 through 2005, Practice Inquiry was introduced to sites in the San Francisco Bay Area as a demonstration effort. Meeting rosters, case logs, a feedback survey, and meeting field notes documented implementation and provided data for a formative, qualitative evaluation. PROGRAM EVALUATION: Of the 30 sites approached, 14 held introductory meetings. As of summer 2006, 98 clinicians in 11 sites continue to hold regularly scheduled group meetings. Of the 118 patient cases presented in the seven oldest groups, clinicianâpatient relationship and treatment dilemmas were most common. Clinician feedback and meeting transcript data provided insights into how busy practitioners shared cases, developed trust, and learned new knowledge/skills for moving forward with patients. DISCUSSION: Ongoing clinician involvement suggests that Practice Inquiry is a feasible, acceptable, and potentially useful set of PBLI methods. Two of the Practice Inquiryâs group learning tasks received comparatively less focus: integrating research evidence with clinical experience and tracking dilemma case outcomes. Future work should focus on reducing the methodological limitations of a demonstration effort and examining factors affecting clinician participation. Set-aside work time for clinicians, or other equally potent incentives, will be necessary for the further elaboration of these PBLI methods aimed at managing uncertainty

Attention training for infants at familial risk of ADHD (INTERSTAARS): study protocol for a randomised controlled trial
Background: Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder that can
negatively impact on an individualâs quality of life. It is pathophysiologically complex and heterogeneous with
different neuropsychological processes being impaired in different individuals. Executive function deficits, including
those affecting attention, working memory and inhibitory control, are common. Cognitive training has been promoted
as a treatment option, based on the notion that by strengthening the neurocognitive networks underlying these
executive processes, ADHD symptoms will also be reduced. However, if implemented in childhood or later, when the
full disorder has become well-established, cognitive training has only limited value. INTERSTAARS is a trial designed to
test a novel approach to intervention, in which cognitive training is implemented early in development, before the
emergence of the disorder. The aim of INTERSTAARS is to train early executive skills, thereby increasing resilience and
reducing later ADHD symptoms and associated impairment.
Methods/design: Fifty 10â14-month-old infants at familial risk of ADHD will participate in INTERSTAARS. Infants
will be randomised to an intervention or a control group. The intervention aims to train early attention skills
by using novel eye-tracking technology and gaze-contingent training paradigms. Infants view animated games
on a screen and different events take place contingent on where on the screen the infant is looking. Infants
allocated to the intervention will receive nine weekly home-based attention training sessions. Control group
infants will also receive nine weekly home visits, but instead of viewing the training games during these visits
they will view non-gaze-contingent age-appropriate videos. At baseline and post treatment, infant attention
control will be assessed using a range of eye-tracking, observational, parent-report and neurophysiological
measures. The primary outcome will be a composite of eye-tracking tasks used to assess infant attention skills.
Follow-up data will be collected on emerging ADHD symptoms when the infants are 2 and 3 years old.
Discussion: This is the first randomised controlled trial to assess the potential efficacy of cognitive training as
a prevention measure for infants at familial risk of ADHD. If successful, INTERSTAARS could offer a promising
new approach for developing early interventions for ADHD.
