2. 1. Evaluation and prognostic significance of premature ventricular contractions in patients without structural heart disease

   Author : Raffaele Scorza; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Introduction: Premature ventricular contractions (PVCs) are a common form of arrhythmia associated with poor prognosis in patients with structural heart disease. However, their prognostic impact on healthy individuals is unclear. READ MORE

4. 2. Extracting Cardiac Information From the Pressure Sensors of a Dialysis Machine

   Author : Mattias Holmer; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hemodialysis; extracorporeal pressure signals; cardiac pressure signal; heart rate; ventricular premature beats; venous needle dislodgement;

   Abstract : This doctoral thesis in biomedical engineering deals with cardiac monitoring using the built-in extracorporeal blood pressure sensors of a hemodialysis machine. Patients treated with hemodialysis often suffer from cardiovascular disease. READ MORE

5. 3. Cerebral intraventricular hemorrhage and post-hemorrhagic ventricular dilatation in preterm infants: new mechanistic insights and potential treatment strategies

   Author : Olga Romantsik; Lund Pediatrik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prematurity; Intraventricular hemorrhage; Post-hemorrhagic ventricular dilatation; White matter injury; Gray matter injury; Preterm rabbits; Extracellular hemoglobin; a-1-microglobulin; animal IVH models; High frequency ultrasound; MRI; corticogenesis;

   Abstract : Intraventricular hemorrhage (IVH) is one of the major co-morbidities of premature birth associated with post-hemorrhagic ventricular dilatation (PHVD) development, long-term neurodevelopmental impairment, behavioral problems, special educational needs, and dependency on social security.Hypothesis and aims: We believe that extravasated blood and further release of extracellular hemoglobin (Hb) are crucial in brain injury following IVH and consequent development of PHVD.

6. 4. Primary Hyperparathyroidism : A Study of Cardiovascular Dysfunction and its Reversibility After Parathyroidectomy

   Author : Inga-Lena Nilsson; Lars-Ove Farnebo; Uppsala universitet; []
   Keywords : Medical sciences; primary hyperparathyroidism; vascular endothelium; heart; heart rate variability; blood pressure; parathyroidectomy; calcium; parathyroid hormone; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Surgery; kirurgi;

   Abstract : Cardiovascular risk in primary hyperparathyroidism (HPT) is controversial, and studies mainly from Europe associate HPT with increased cardiovascular morbidity and mortality. Cardiovascular morphology and function were evaluated prospectively in 31 consecutive HPT patients (mean serum calcium 2.97±0. READ MORE

7. 5. Cardiovascular structure and function in obesity. The impact of body composition, sleep apnea and sustained weight loss

   Author : Dimitris Kardassis; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obesity; weight loss; cardiac function; cardiac structure; inflammation; intima-media thickness; obstructive sleep apnoea;

   Abstract : Background: Obesity is associated with disturbances in cardiovascular structure and function varying along with the degree of fatness, but the mechanisms underlying this co-variation are unclear. Short-term weight loss appears to have favourable effects on the cardiovascular system, but whether such improvements are maintained in the long run is unknown. READ MORE
