The Study to Explore Early Development (SEED): a multisite epidemiologic study of autism by the Centers for Autism and Developmental Disabilities Research and Epidemiology (CADDRE) network

The Study to Explore Early Development (SEED), a multisite investigation addressing knowledge gaps in autism phenotype and etiology, aims to: (1) characterize the autism behavioral phenotype and associated developmental, medical, and behavioral conditions and (2) investigate genetic and environmental risks with emphasis on immunologic, hormonal, gastrointestinal, and sociodemographic characteristics. SEED uses a case-control design with population-based ascertainment of children aged 2-5 years with an autism spectrum disorder (ASD) and children in two control groups-one from the general population and one with non-ASD developmental problems. Data from parent-completed questionnaires, interviews, clinical evaluations, biospecimen sampling, and medical record abstraction focus on the prenatal and early postnatal periods. SEED is a valuable resource for testing hypotheses regarding ASD characteristics and causes.

A patient-derived perspective of health-related quality of life with peripheral arterial disease

PURPOSE

To evaluate the effects of peripheral artery disease (PAD) on health-related quality of life (HRQoL) from the patient's perspective to establish a foundation for systematic PAD-specific HRQoL assessment in this population.

DESIGN

Grounded theory methodology.

METHODS

Open-ended, tape-recorded interviews were conducted with 38 patients (24 men, 14 women) 44 to 83 years old (mean 65) from two US medical centers to report patient experience of PAD and its perceived effects on HRQoL. Tapes were transcribed and analyzed to identify themes and conceptual domains pertinent to the experience of PAD in this population.

RESULTS

Seven major themes were identified: (a) delay in diagnosis and frustration with management of disease; (b) pain; (c) limitation in physical functioning; (d) limitation in social and role functioning; (e) compromise of self; (f) uncertainty and fear; and (g) adaptation to the effects of the disease and demonstration of resiliency.

CONCLUSIONS

These findings indicate important psychosocial and emotional consequences of PAD that existing HRQoL questionnaires do not indicate. More complete data might lead to greater understanding of the effects of PAD, serving as the foundation for a more sensitive instrument to assess HRQoL as a basis for more effective interventions.

The development of a computerised equipment and drug calculator for use in resuscitation

OBJECTIVES

To design a computerised system of calculating resuscitation requirements and to test this system to ensure that it gives accurate and fast results, so that it could potentially be used in the resuscitation of patients in a accident and emergency (A&E) department.

METHODS

Using internet based technology we have developed a program that runs inside most web browsers and can be used to calculate several parameters (including endotracheal tube dimensions and drug doses). The only value that is required is the age of the patient. The weight is calculated and can be adjusted if known. The resuscitation requirement calculations are made from the weight. The program was then tested on staff members in the department to calculate theoretical resuscitation requirements for paediatric and adult patients. Accuracy and speed of the computerised calculator was compared with the conventional paper based calculation methods.

RESULTS

Subjects performed better using the computerised calculator. On average they made significantly fewer errors (21.4% more accurate than using conventional methods) and were three times faster.

CONCLUSION

The computerised calculator has proved, in a controlled setting, to be a more accurate and faster way of calculating resuscitation requirements than conventional methods.
