1. 6. Lung function in relation to exercise capacity in health and disease

   Författare :Amir Farkhooy; Andrei Malinovschi; Christer Janson; Hans Hedenström; Harrpa Arnardottir; Ann Ekberg Jansson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise capacity; Exercise test; Lung function; Spirometri; Diffusion capacity; COPD; Pulmonary hypertension; Clinical Physiology; Klinisk fysiologi;

   Sammanfattning : Background: Exercise capacity (EC) is widely recognized as a strong and independent predictor of mortality and disease progression in various diseases, including cardiovascular and pulmonary diseases. Furthermore, it is generally accepted that exercise capacity in healthy individuals and in patients suffering from cardiovascular diseases is mainly limited by the maximum cardiac output. LÄS MER

3. 7. Quantification of pulmonary scintigraphy

   Författare :Jiahua Xu; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Emphysema; Inhomogeneity; Perfusion; scintigraphy; SPECT; 99mTc-Technegas; Ventilation; V Q;

   Sammanfattning : Modern nuclear medicine techniques, such as SPECT (single photon emission computed tomography), enable quantification and localisation of lung function in small lung elements, but appropriate methods are not yet available. The aim of the present project was therefore to develop and evaluate methods for mapping lung function in planar scintigrams and in SPECT. LÄS MER

4. 8. Clinical evaluation and implications of left atrial remodeling in atrial fibrillation : From silent cerebral lesions and atrial stunning to novel electrocardiographic tools for prediction of arrhythmia outcome

   Författare :Panagiotis Arvanitis; Carina Blomström-Lundqvist; Mårten Rosenqvist; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; left atrial remodeling; recurrence; new-onset; silent cerebral lesions; white matter hyperintensities; cardioversion; pulmonary vein isolation; risk factors; electrocardiographic predictors; P-wave indices; machine learning; predictive models; Covid-19;

   Sammanfattning : Atrial fibrillation (AF) is the most common cardiac arrhythmia. Left atrial (LA) remodeling and reverse remodeling are associated with cerebral involvement and cognitive function (CF) changes. Risk stratification for AF related outcomes is essential in the management of patients with AF. LÄS MER

5. 9. Outcomes and Implications of Nasal Measurements in Obstructive Sleep Apnea

   Författare :Hans Christian Hoel; Lund näs- och halssjukdomar Öron-; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstructive sleep apnea OSA ; Respiratory system diagnostic technique; nasal obstruction; Sleep hypopnea; Rhinomanometry;

   Sammanfattning : BackgroundObstructive sleep apnea (OSA) is a prevalent disorder and symptoms of nasal obstruction are highly prevalent in OSA. Treatment of nasal obstruction in OSA patients has shown modest and variable outcomes in reducing the apnea hypopnea index (AHI), but significant improvements in other indicators, such as sleep quality and daytime sleepiness as well as reductions in arousals have been observed.

7. 10. Surfactant metabolism in the newborn : the impact of ventilation strategy and lung disease

   Författare :Kajsa Bohlin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Surface active agents; pulmonary surfactant; respiratory distress syndrome; stable isotope; artificial respiration; continuous positive airway pressure; metabolism; rabbit; compliance; preterm; newborn;

   Sammanfattning : Developmental deficiency in pulmonary surfactant leads to respiratory distress syndrome (RDS) in preterm infants, but all newborns may have impaired surfactant metabolism secondary to lung disease or ventilator induced lung injury. Exogenous surfactant treatment is usually administered in conjunction with mechanical ventilation. LÄS MER
