Practical Assessment of Maternal Cardiovascular Risk in Pregnancy

CONGENITAL HEART DISEASE, Issue 5 2008
Nazanin Moghbeli MD
ABSTRACT Cardiovascular disease in pregnancy is the most common cause of maternal mortality in the developed world and an important cause of heart failure, stroke, and arrhythmia. As more children with congenital heart disease survive into adulthood, there is a more pressing need to understand the risks that pregnancy poses for these women. Pregnancy, labor, and delivery increase the hemodynamic stress on the cardiovascular system and place women with heart disease at increased risk of cardiovascular complications, which include heart failure and death. Systematic assessment of pregnancy risk in these women, ideally before conception, is essential in optimizing maternal and fetal outcomes. This article describes the process of assessing risk of pregnancy-associated cardiovascular complications in women with structural heart disease. We review the current literature on pregnancy risk in women with complex congenital lesions, valvular heart disease, cardiomyopathy, and aortopathy, and suggest an approach to risk stratification. Based on a review of the literature, we report features that pose an increased risk of adverse maternal and fetal outcomes, which include poor maternal functional status; prior history of heart failure, arrhythmia, or cerebral vascular events; cyanosis; poor systemic ventricular function; and severe aortic or mitral stenosis. Pulmonary hypertension and Eisenmenger syndrome place women at exceedingly high risk for cardiovascular complications in pregnancy, including maternal and fetal death. [source]

Practical assessment of project performance: the ,potential impact' approach,

PUBLIC ADMINISTRATION & DEVELOPMENT, Issue 5 2000
Michael Hubbard
This article sets out an approach to assessing project performance, using ,potential impact' of the project. Its purpose is to assist project design and evaluation. In project design, potential impacts of alternative activities on the project objective are compared, in order to select activities with the greatest impact. In project evaluation, potential and actual impacts of a project are compared. Additional benefits of the approach are that it indicates ,value for money' of development assistance invested in projects, and easier tracing of reasons for underachievement in projects to weaknesses in their design or management. Limitations are that it relies on informed judgement of the planners or evaluators and the categories for rating performance may unavoidably be broad. It complements the logical framework approach by providing a practical design and evaluation tool. Copyright © 2000 John Wiley & Sons, Ltd. [source]

Effects of back care education in elementary schoolchildren

ACTA PAEDIATRICA, Issue 8 2000
G Cardon
The purpose of this study was to investigate the effects of a back care education programme, consisting of six sessions of 1 h each, in fourth- and fifth-grade elementary schoolchildren. Testing consisted of a practical performance and a back care knowledge test. Forty-two subjects and 36 controls performed a pre-test and were tested within 1 wk after the programme. To monitor effects and follow-up effects on a larger sample, 82 different pupils were tested within 1 wk after the programme and 116 other children 3 mo after. Both larger samples were compared with one group of 129 controls. Interrater reliability for the test items of the practical assessment was high; intraclass correlation coefficients varied from 0.785 to 0.980. In the pre/post design study, interaction between time and condition was significant for the sum score of the practical assessment and for the knowledge test (p < 0.001), with higher scores for the intervention group (15% improvement for the knowledge test score, 31.6% for the practical sum score). Significantly higher sum scores for the knowledge test and for all practical assessment items were found in the intervention groups, tested within 1 wk and 3 mo after the programme, in comparison with the control group (p <0.001). Conclusion: The effectiveness of a primary educational prevention programme on back care principles was demonstrated in this study. Effectiveness, long-term outcomes and behavioural changes need further evaluation to optimize back care prevention programmes for elementary schoolchildren. [source]

Inspection time predicts individual differences in everyday functioning among elderly adults: Testing discriminant validity

AUSTRALASIAN JOURNAL ON AGEING, Issue 2 2009
Tess Gregory
Aim:, Inspection time (IT) is a processing speed measure, recently investigated as a biomarker of ageing. This study examined whether earlier IT predicts subsequent problems in everyday functioning in community-dwelling elderly people. Methods:, Participants completed IT at baseline, 6 months and 18 months. At 42 months, two groups of 15 elderly people matched for education and age (74,88 years) and selected for slower or faster baseline IT, completed a fourth estimate of IT and a practical assessment of everyday functioning (Timed Instrumental Activities of Daily Living , Adelaide). Results:, At 42 months, the group with slower baseline IT had significantly poorer performance (slower completion, higher errors) on more than half of the everyday functioning tasks. Conclusion:, Slower IT predicts difficulties up to 4 years later in everyday functioning of elderly adults, providing discriminant validation for IT as a biomarker for future changes. [source]

Pumping-Induced Drawdown and Stream Depletion in a Leaky Aquifer System

GROUND WATER, Issue 2 2007
James J. Butler Jr
The impact of ground water pumping on nearby streams is often estimated using analytic models of the interconnected stream-aquifer system. A common assumption of these models is that the pumped aquifer is underlain by an impermeable formation. A new semianalytic solution for drawdown and stream depletion has been developed that does not require this assumption. This solution shows that pumping-induced flow (leakage) through an underlying aquitard can be an important recharge mechanism in many stream-aquifer systems. The relative importance of this source of recharge increases with the distance between the pumping well and the stream. The distance at which leakage becomes the primary component of the pumping-induced recharge depends on the specific properties of the aquifer, aquitard, and streambed. Even when the aquitard is orders of magnitude less transmissive than the aquifer, leakage can be an important recharge mechanism because of the large surface area over which it occurs. Failure to consider aquitard leakage can lead to large overestimations of both the drawdown produced by pumping and the contribution of stream depletion to the pumping-induced recharge. The ramifications for water resources management and water rights adjudication can be significant. A hypothetical example helps illustrate these points and demonstrates that more attention should be given to estimating the properties of aquitards underlying stream-aquifer systems. The solution presented here should serve as a relatively simple but versatile tool for practical assessments of pumping-induced stream-aquifer interactions. However, this solution should not be used for such assessments without site-specific data that indicate pumping has induced leakage through the aquitard. [source]
