- OBJECTIVE: To investigate whether change in objective signs during up-titration of angiotensin-converting enzyme (ACE)-inhibitors in patients with chronic heart failure affect perception of information about medicines and subjective activities such as self-care. METHODS: Consecutive patients referred for up-titration of ACE-inhibitors were included. Patients were given the Satisfaction with Information about Medicines Scale and the European Heart Failure Self-Care Behaviour Scale at their first visit and when the target dose was reached. Blood pressure, pulse and s-creatinine were measured at each visit. RESULTS: Relationships were found between change in systolic (r = 0.224, p = 0.044) and diastolic (r = 0.361, p = 0.001) blood pressure and change in self-care scores and were also observed at baseline (r = 0.324, 0.398, p = 0.001, 0.000) and follow-up (r = 0.317, 0.253, p = 0.004, 0.022). Diastolic blood pressure correlated with the "potential problem of medication" score (r= -0.263, p = 0.007). CONCLUSION: Patients with a more advanced disease usually have a lower blood pressure. Hence, the relationship between blood pressure and self-care scores might indicate that patients are more motivated to adhere to prescriptions the more advanced the stage of their disease.

- Aims: Diuretics are recommended for treating congestive symptoms in heart failure (HF). The short- and long-term prognostic effects of diuretic treatment at hospital discharge have not been studied in randomized clinical trials or in a Western world population. We aimed to determine the association of diuretic treatment at discharge with the risk of short-and long-term all-cause mortality in real-life patients in Sweden with HF irrespective of EF. Methods and results: From a Swedish nationwide HF register 26,218 patients discharged from hospital were included in the present study. A total of 87% of patients were treated with and 13% were not treated with diuretics at hospital discharge. In a 1:1 propensity score-matched cohort of 6564 patients, the association of diuretic treatment at hospital discharge with the risk of 90-day all-cause mortality was neutral (HR 0.89, 95% CI 0.74–1.07, p = 0.21) whereas the risk of long-term all-cause mortality (median follow-up: 2.85 years) was increased (HR 1.15, 95% CI 1.06–1.24, p < 0.001). Conclusion: Diuretic treatment at hospital discharge was not associated with short-term mortality whereas it was associated with increased long-term mortality. Although we accounted for a wide range of clinical features, measured or unmeasured factors could still explain this increase in risk. However, our results suggest that diuretic treatment at hospital discharge may be regarded as a marker of increased long-term mortality.

- We sought to describe the clinical presentation, management, and 6-month outcomes in women with peripartum cardiomyopathy (PPCM) globally.In 2011, >100 national and affiliated member cardiac societies of the European Society of Cardiology (ESC) were contacted to contribute to a global registry on PPCM, under the auspices of the ESC EURObservational Research Programme. These societies were tasked with identifying centres who could participate in this registry. In low-income countries, e.g. Mozambique or Burkina Faso, where there are no national societies due to a shortage of cardiologists, we identified potential participants through abstracts and publications and encouraged participation into the study. Seven hundred and thirty-nine women were enrolled in 49 countries in Europe (33%), Africa (29%), Asia-Pacific (15%), and the Middle East (22%). Mean age was 31 ± 6 years, mean left ventricular ejection fraction (LVEF) was 31 ± 10%, and 10% had a previous pregnancy complicated by PPCM. Symptom-onset occurred most often within 1 month of delivery (44%). At diagnosis, 67% of patients had severe (NYHA III/IV) symptoms and 67% had a LVEF ≤35%. Fifteen percent received bromocriptine with significant regional variation (Europe 15%, Africa 26%, Asia-Pacific 8%, the Middle East 4%, P < 0.001). Follow-up was available for 598 (81%) women. Six-month mortality was 6% overall, lowest in Europe (4%), and highest in the Middle East (10%). Most deaths were due to heart failure (42%) or sudden (30%). Re-admission for any reason occurred in 10% (with just over half of these for heart failure) and thromboembolic events in 7%. Myocardial recovery (LVEF > 50%) occurred only in 46%, most commonly in Asia-Pacific (62%), and least commonly in the Middle East (25%). Neonatal death occurred in 5% with marked regional variation (Europe 2%, the Middle East 9%).Peripartum cardiomyopathy is a global disease, but clinical presentation and outcomes vary by region. Just under half of women experience myocardial recovery. Peripartum cardiomyopathy is a disease with substantial maternal and neonatal morbidity and mortality.

- The effective use of modern control theory requires suitable mathematical models of the objects to be controlled and of the disturbances. Paper machines have been controlled digitally for a long time. Digital control of basis weight and moisture content is in fact one of the few examples where a digital computer and sensors form a standard package. In spite of this there are still significant gaps in our knowledge of paper machine dynamics. This paper attempts to fill a few of these. The paper is based on measurements on full scale paper machines and on a pilot plant at the Swedish Forest Products Research Laboratory (STFI). The experiments on the industrial plants were performed using control computers with appropriate instrumentation both on craft paper and newsprint machines. The experiments on the pilot plant were carried out with different fibre, clay and water mixtures. These experiments gave insight into the effect of the pulp characteristics on paper machine dynamics. Optical gauges capable of measuring low fibre concentrations were used in the experiments. This made detailed analysis of the mixing dynamics possible. The possibility of obtaining better control through the incorporation of such gauges could also be evaluated.
