2. 21. Epidemiology of viral respiratory infections with focus on in-hospital influenza transmission

   Author : Martina Sansone; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; influenza; rhinovirus; infection-control; hospital outbreak; nosocomial; phylogeny; polymerase chain reaction; viral transmission; whole-genome sequencing; system dynamics;

   Abstract : Human Rhinoviruses (HRV) and influenza viruses are respiratory pathogens which represent a major global disease burden. Healthcare-associated infections (HCAI) are increasingly recognized as a public health concern, but limited data has been published on the characteristics and epidemiology of HCAI caused by respiratory viruses.

4. 22. Short- and long-term outcomes after aneurysmal subarachnoid hemorrhage

   Author : Sandra Bjerkne Wenneberg; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aneurysmal subarachnoid hemorrhage; delayed cerebral ischemia; biomarkers; inflammation; heart rate variability; long-term outcomes; mental fatigue;

   Abstract : Aneurysmal subarachnoid hemorrhage (aSAH) is a sudden and devastating event with significant morbidity and mortality. The development of delayed cerebral ischemia (DCI) is a major contributor to the observed high morbidity. Prompt detection of these injuries remains a considerable challenge. READ MORE

5. 23. Patient stratification and treatment effects in diseases with disturbed cardiac function

   Author : Gabriel Granåsen; Urban Wiklund; Frida Sandberg; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biostatistics; Heart rate variability; Cardiac amyloidosis; hypertrophic cardiomyopathy; cluster analysis; Echocardiography; Long QT syndrome; Pediatric; Statins; Coronary artery calcium; Computer tomography; Machine learning; Predictive modeling;

   Abstract : Background: Cardiovascular disease characteristics are often measured using a combination of different measurement modalities. By combining information from these modalities using statistical modelling we can gain additional knowledge about these diseases. READ MORE

6. 24. Prognostic implications of exercise induced and ambulatory ischemia in patients with stable angina pectoris

   Author : Lennart Forslund; Karolinska Institutet; Karolinska Institutet; []
   Keywords : angina pectoris; exercise testing; ambulatory ECG; signs of ischemia; heart rate variability; catecholamines; metoprolol; verapamil; prognosis;

   Abstract : Results from exercise testing and ambulatory ECG registration were studied in 809 patients with stable angina pectoris; special attention was paid to signs of ischemia during both tests. Autonomic nervous system activity was investigated by measurements of heart rate variability (HRV) and catecholamines in plasma and urine. READ MORE

7. 25. Atrial Fibrillation after Coronary Artery Bypass Surgery : A Study of Causes and Risk Factors

   Author : Lena Jidéus; Dan Lindblom; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Atrial fibrillation; catecholamines; coronary artery bypass surgery; heart rate variability; neuropeptides; premature atrial contraction; thoracic epidural anaesthesia; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

   Abstract : The aim was to study pathophysiological mechanisms and risk factors for developing atrial fibrillation (AF) after coronary artery bypass grafting (CABG), and the effect of thoracic epidural anaesthesia (TEA).The study comprised 141 patients undergoing CABG, including 45 patients randomised for TEA intra- and postoperatively.
