21. Apnea, small for date and autonomic imbalance : risk factors in relation to SIDS
Sammanfattning : SIDS (Sudden Infant Death Syndrome) is defined as an infant who has died suddenly and its cause "remains unexplained after a thorough case investigation, including performance of a complete autopsy, examination of the death scene, and review of the clinical history". An infant who during sleep has been found apneic, pale or cyanotic and limp, and has required either vigorous stimulation or cardiopulmonary resuscitation is defined to have been affected of an Apparent Life Threatening Event (ALTE).

22. Repolarization studies in the long QT syndrome
Sammanfattning : ABSTRACT Background: Sudden cardiac death in the young is predominantly caused by inherited cardiac conditions. Long QT syndrome (LQTS) is one of the most common of these disorders. Since risk stratification relies largely upon the heart rate (HR) corrected QT interval (QTc), it is crucial to identify an appropriate method for QT correction. LÄS MER
23. Significance of Human Papillomavirus (HPV) Analysis for the Detection of Precancerous Cervical Lesions : Impact of Self Sampling
Sammanfattning : Cervical cancer is the second most common cancer, with about 500 000 new cases per year among women worldwide. With a well-organized screening programme the number of cases can be reduced by more than 50%. In spite of having such a screening programme there are still around 450 new cases yearly in Sweden.

24. Adaptation of ventricular repolarization to heart rate change in humans
Sammanfattning : Background: Life-threatening cardiac rhythm disturbances and sudden death are common manifestations of heart disease. Disturbances in electrical recovery (ventricular repolarization; VR) are important mechanisms behind ventricular arrhythmias, which often occur in relation to changes in heart rate (HR). LÄS MER
25. Measurements of physical workload with special reference to energy expenditure and work postures
Sammanfattning : Background: There is a need in preventive ergonomics for accurate and valid methods of quantifying exposure to physical workload. Aims: Two technical instruments were evaluated for quantifying occupational physical workloads: 1) A heart rate (HR) monitor system to measure energy expenditure and 2) An inclinometer system based on triaxial accelerometers to measure work postures.
