1.	Dietrich, M., et al. (author) Monitoring of active galactic nuclei. IV. The Seyfert 1 galaxy NGC 4593 1994 In: Astronomy and Astrophysics. - 0004-6361 .- 1432-0746. ; 284:1, s. 33-4343 Journal article (peer-reviewed)abstract Results of a five-month campaign of optical monitoring the Seyfert 1 galaxy NGC 4593 are presented. High resolution Halpha and Hbeta spectra and direct images in the Johnson U, B, V, R and I bands were obtained between January and June 1990. The emission lines and the continuum showed strong variations on time scales of weeks to days. The Halpha line varied by more than 30% within only 5 days. Cross-correlating the light curves of the Balmer lines with that of the optical continuum gives a lag of around 4 days. Therefore, this low luminosity Seyfert galaxy may have one of the smallest broad line regions known so far

5.	Ljungman, S., et al. (author) Factors associated with time to first dialysis-associated peritonitis episode: Data from the Peritonitis Prevention Study (PEPS) 2023 In: Peritoneal Dialysis International. - 0896-8608. ; 43:3, s. 241-251 Journal article (peer-reviewed)abstract Introduction: Peritonitis remains a potentially serious complication of peritoneal dialysis (PD) treatment. It is therefore important to identify risk factors in order to reduce the incidence of peritonitis. The aim of the present analysis was to identify factors associated with time to first peritonitis episode. Methods: Incident PD patients from 57 centres in Europe participated in the prospective randomised controlled Peritonitis Prevention Study (PEPS) from 2010 to 2015. Peritonitis-free, self-care PD patients >= 18 years were randomised to a retraining or a control group and followed for 1-36 months after PD initiation. The association of biochemical, clinical and prescription data with time to first peritonitis episode was studied. Results: A first peritonitis episode was experienced by 33% (223/671) of participants. Univariable Cox proportional hazard regression showed a strong association between the time-updated number of PD bags connected per 24 h (PD bags/24 h) and time to first peritonitis episode (HR 1.35; 95% confidence interval (CI) 1.17-1.57), even after inclusion of PD modalities in the same model. Multivariable Cox regression revealed that the factors independently associated with time to first peritonitis episode included age (HR 1.16 per 10 years; 95% CI 1.05-1.28), PD bags/24 h (HR 1.32; 95% CI 1.13-1.54), serum albumin >35 g/L (HR 1.39; 95% CI 1.06-1.82) and body weight per 10 kg (HR 1.10; 95% CI 1.01-1.19). Conclusion: This study of incident PD patients indicates that older age, greater number of PD bags connected/24 h, higher body weight and hypoalbuminaemia are independently associated with a shorter time to first peritonitis episode.
