- BackgroundThere is a conceptual overlap between negative and depressive symptoms, requiring further exploration to advance the understanding of negative symptoms. The aim of this study was to examine psychometric properties of the Clinical Assessment Interview for Negative Symptoms (CAINS) in patients with depression, and to explore the relationship between the negative and affective symptoms domains.MethodsFifty-one patients with a depressive episode were included and interviewed with the CAINS and the Brief Psychiatric Rating Scale—Expanded (BPRS-E). Self-reported depressive symptoms were collected with the Montgomery-Asberg Depression Rating Scale (MADRS-S). Inter-rater agreement, internal consistency and validity measures were examined, as were correlations between negative and affective symptoms.ResultsThe intraclass correlation for the CAINS motivation and pleasure subscale (CAINS-MAP) was 0.98 (95% CI 0.96–0.99) and that for the expressional subscale (CAINS-EXP) was 0.81 (95% CI 0.67–0.89). Cronbach’s alpha was 0.71 (95% CI 0.57–0.82) for the CAINS-MAP and 0.86 (95% CI 0.79–0.92) for the CAINS-EXP. The correlation with the negative symptoms subscale of the BPRS-E was 0.35 (p = 0.011, blinded/different raters) or 0.55 (p < 0.001, not blinded/same rater). The CAINS-MAP correlated with the affective symptoms subscale of the BPRS-E (r = 0.39, p = 0.005) and the MADRS-S total score (r = 0.50, p < 0.001), but not with anxiety symptoms.ConclusionsNegative symptoms in depression can be assessed with the CAINS with good inter-rater agreement and acceptable internal consistency and validity. There are associations between negative and depressive symptoms that call for further exploration.

- BACKGROUND:Idiopathic fibrosing interstitial pneumonia consists of many subtypes, most associated with a poor prognosis. The aim of the study was to evaluate diagnostic procedures and treatment as well as survival in patients with idiopathic fibrosing interstitial pneumonia.METHODS:This study comprised 175 patients with idiopathic fibrosing interstitial pneumonia (ICD 10 code J84) that had been diagnosed at Uppsala University Hospital, during 2005 to 2012. Patient records were reviewed concerning: gender, age, smoking, occupational exposure, comorbidities, procedures, lung function, and treatment. Information on survival and cause of death was collected.RESULTS:A total of 98% had been examined with computed tomography, 93% with spirometry, 49% with measurement of diffusion capacity, 48% with bronchoalveolar lavage, and 23% with lung biopsy. Prednisolone had been prescribed to 74% while N-acetylcysteine (NAC) and omeprazole were prescribed to 54%, respectively. Five-year survival was 46%. Mortality was associated with high age, low diffusion capacity, and the use of NAC.CONCLUSION:High age and a low diffusion capacity are related to shorter survival in idiopathic fibrosing interstitial pneumonia. We also unexpectedly found that the use of NAC was related to shorter survival. A relatively low proportion of the patients were examined with diffusion capacity measurement. Thus, there is a possibility to improve diagnostic procedures and thereby improve estimation of prognosis in fibrotic lung disease.
