Queries from Twin Project
=========================

At Analytikerna and Lentus, we have been doing the systems and field
work for a big research project. This project is a collaboration
between the Institute of Environmental Medicine at Karolinska
Institutet Stockholm and the Section on Clinical Research in Aging and
Psychology at the University of Southern California.

The project involves a screening part where all twins in Sweden older
than 65 years are interviewed by telephone. Twins who meet certain
criteria are passed on to the next stage. In this latter stage, twins
who want to participate are visited by a doctor/nurse team. Some of the
examinations include physical and neuropsychological examination,
laboratory testing, neuroimaging, psychological status assessment, and
family history collection. In addition, data are collected on medical
and environmental risk factors.

More information about Twin studies can be found at:

The latter part of the project is administered with a Web interface
written using Perl and MySQL.

Each night all data from the interviews are moved into a MySQL database.
