    • Identification and prevalence of adventitious lung sounds in a general adult population 

      Aviles Solis, Juan Carlos (Doctoral thesis; Doktorgradsavhandling, 2020-04-01)
      The main goal of this work was to describe the prevalence of adventitious lung sounds (wheezes and crackles) in a general population. We obtained lung sound recordings from 4033 participants in the 7th survey of the Tromsø. We observed a crude prevalence of adventitious lung sounds in 28% of the participants; 18 % had wheezes, 13% had crackles. Age, female sex, self-reported asthma, and current ...

    • Inspiratory crackles-early and late-revisited: identifying COPD by crackle characteristics 

      Melbye, Hasse; Aviles Solis, Juan Carlos; Jacome, Cristina; Pasterkamp, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-05)
      Background The significance of pulmonary crackles, by their timing during inspiration, was described by Nath and Capel in 1974, with early crackles associated with bronchial obstruction and late crackles with restrictive defects. Crackles are also described as ‘fine’ or ‘coarse’. We aimed to evaluate the usefulness of crackle characteristics in the diagnosis of chronic obstructive pulmonary disease ...

    • International perception of lung sounds: a comparison of classification across some European borders 

      Aviles Solis, Juan Carlos; Vanbelle, Sophie; Halvorsen, Peder Andreas; Francis, Nick; Cals, Jochem W L; Andreeva, Elena A; Marques, Alda; Piirila, Paivi; Pasterkamp, Hans; Melbye, Hasse (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-18)
      Introduction: Lung auscultation is helpful in the diagnosis of lung and heart diseases; however, the diagnostic value of lung sounds may be questioned due to interobserver variation. This situation may also impair clinical research in this area to generate evidence-based knowledge about the role that chest auscultation has in a modern clinical setting. The recording and visual display of lung sounds ...

    • Interrater and intrarater agreement on heart murmurs 

      Andersen, Stian; Davidsen, Anne Herefoss; Schirmer, Henrik; Melbye, Hasse; Spigt, Marcus; Aviles Solis, Juan Carlos (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-04)
      Objective: To investigate interrater and intrarater agreement between physicians and medical students on heart sound classification from audio recordings, and factors predicting agreement with a reference classification.<p> <p>Design: Intra- and interrater agreement study. <p>Subjects: Seventeen GPs and eight cardiologists from Norway and the Netherlands, eight medical students from Norway. <p>Main ...

    • Prediction of chronic heart failure and chronic obstructive pulmonary disease in a general population: the Tromsø study 

      Melbye, Hasse; Stylidis, Michael; Aviles Solis, Juan Carlos; Averina, Maria; Schirmer, Henrik (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-07)
      <i>Aims</i> - Heart failure (HF) and chronic obstructive pulmonary disease (COPD) are main causes of dyspnoea, and echocardiography and spirometry are essential investigations for these diagnoses. Our aim was to determine the prevalence of HF and COPD in a general population, also how the diseases may be identified, and to what extent their clinical characteristics differ.<br><br> <i>Methods and ...

    • Prevalence and clinical associations of wheezes and crackles in the general population: The Tromsø study 

      Aviles Solis, Juan Carlos; Jacome, Cristina; Davidsen, Anne Herefoss; Einarsen, R; Vanbelle, Sophie; Pasterkamp, Hans; Melbye, Hasse (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-11)
      <i>Background</i> - Wheezes and crackles are well-known signs of lung diseases, but can also be heard in apparently healthy adults. However, their prevalence in a general population has been sparsely described. The objective of this study was to determine the prevalence of wheezes and crackles in a large general adult population and explore associations with self-reported disease, smoking status and ...

    • The use of spectrograms improves the classification of wheezes and crackles in an educational setting 

      Aviles Solis, Juan Carlos; Storvoll, Ingrid; Vanbelle, Sophie; Melbye, Hasse (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-21)
      Chest auscultation is a widely used method in the diagnosis of lung diseases. However, the interpretation of lung sounds is a subjective task and disagreements arise. New technological developments like the use of visSual representation of sounds through spectrograms could improve the agreement when classifying lung sounds, but this is not yet known. In this study, we tested if the use of spectrograms ...
