- OBJECTIVES: The Swedish Pulmonary Arterial Hypertension Register (SPAHR) is an open continuous register, including pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) patients from 2000 and onwards. We hereby launch the first data from SPAHR, defining baseline characteristics and survival of Swedish PAH and CTEPH patients.DESIGN: Incident PAH and CTEPH patients 2008-2014 from all seven Swedish PAH-centres were specifically reviewed.RESULTS: There were 457 PAH (median age: 67 years, 64% female) and 183 CTEPH (median age: 70 years, 50% female) patients, whereof 77 and 81%, respectively, were in functional class III-IV at diagnosis. Systemic hypertension, diabetes, ischaemic heart disease and atrial fibrillation were common comorbidities, particularly in those >65 years. One-, 3- and 5-year survival was 85%, 71% and 59% for PAH patients. Corresponding numbers for CTEPH patients with versus without pulmonary endarterectomy were 96%, 89% and 86% versus 91%, 75% and 69%, respectively. In 2014, the incidence of IPAH/HPAH, associated PAH and CTEPH was 5, 3 and 2 per million inhabitants and year, and the prevalence was 25, 24 and 19 per million inhabitants.CONCLUSION: The majority of the PAH and CTEPH patients were diagnosed at age >65 years, in functional class III-IV, and exhibiting several comorbidities. PAH survival in SPAHR was similar to other registers.

- An open, noncomparative, Nordic multicenter study was carried out during 1991-1992 to evaluate the 5-HT3 receptor antagonist tropisetron (Navoban) as an antiemetic agent for various types of cancer chemotherapy. A total of 630 patients were recruited from 15 centers in Sweden, Denmark, and Finland. Gynecological cancers (60%), breast cancer (15%), and lung cancer (10%) were the main diagnoses. Prior experience of chemotherapy was documented in 338 patients (54%). In 260 patients (41%), cisplatin was part of the cytostatic regimen. Carboplatin (23%), doxorubicin (27%), and epidoxorubicin (24%) were also frequently included. In all, 23 cytostatic agents were used in various combinations. The mean number of courses studied was 4.6 (range 1-19). Altogether, 394 of 619 evaluable patients (64%) were completely protected from acute nausea and vomiting during the first course of chemotherapy. Delayed nausea and vomiting were completely prevented in 45%-73% (days 2-6) in the complete series. Treatment efficacy remained stable (60%-79%) during ten consecutive courses of chemotherapy. With noncisplatin regimens, complete protection from acute nausea and vomiting was achieved in 72% compared with 52% for cisplatin regimens (P < 0.0001). Patients without prior experience of chemotherapy had higher control rates of acute nausea and vomiting (72%) compared to patients treated before (57%) during the first course, but not later on. There were no differences in delayed nausea and vomiting.

Wavelet analysis of in-cylinder LDV velocity measurements
- 1996

- The Discrete Wavelet Transform (DWT) is a new way to analyze gas flow measurements in engine cylinders. The DWT technique differs significantly from the Fast Fourier Transform (FFT) in that with the former, the analysis of information can be done in both the time domain and frequency domain. The basic theory of wavelets is presented and the use of DWT is demonstrated on information derived from laser Doppler velocity (LDV) measurements for different geometrical configurations of combustion chambers in a natural gas converted truck engine.

Small things and wide horizons from a Birka perspective

- The excavations of one of the plots in the Black Earth at Birka revealed an unusually large number of objects associated with long-distance eastern contacts. Among the objects was a Volga Bulgarian pot and a hoard containing Volga Bulgarian imitations of dirhams. The surprisingly high proportion of Volga Bulgarian coins in the hoard indicates that the person(s) who lived on the plot in the mid tenth century may actually have spent time in Volga Bulgaria. It is no coincidence that the finds point to this region. In the tenth century several important trade routes converged in this area, where Rus’, Khazarian and Muslim merchants came to trade.

Acute Pulmonary Embolism : not just an acute condition after all
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Acute pulmonary embolism (PE) is the third most common cardiovascular disease following myocardial infarction and stroke. Despite diagnostic improvements, the diagnosis of PE is still associated with many difficulties, as the symptoms of an acute PE are nonspecific. Even though an acute PE is associated with a high short-term mortality, less attention has been given to long-term mortality. In addition, the clinical course following an acute PE may be accompanied by substantial morbidity, and one feared complication is chronic thromboembolic pulmonary hypertension (CTEPH), a progressive pulmonary vasculopathy. In addition to CTEPH, increasing evidence suggests that a large proportion of patients report persistent functional impairment several years after an acute PE. Recently, the term chronic thromboembolic pulmonary disease (CTEPD) has been proposed for those with remaining symptoms and signs of residual thrombotic material in the pulmonary arteries. Methods and Results: A nation-wide Swedish cohort of all patients (n= 5793) diagnosed with an acute PE in 2005 was identified. The incidence of PE was 0.6/1000 person-years, and during a 4-year follow-up, the mortality was more than doubled compared with an age- and sex-matched control group. We found that the acute PE associated with multiple comorbidities, and with cardiovascular diseases in particular. All surviving patients in 2007 (n=3510) were invited to answer a questionnaire regarding dyspnea and related comorbidities. We demonstrated a substantially higher prevalence of both exertional dyspnea (53.0% vs. 17.3%) and wake-up dyspnea (12% vs. 1.7%) in patients compared to controls from the Northern Sweden MONICA study. Furthermore, PE associated independently with dyspnea in a multivariable analysis. Through a manual review of approximately 10 % of the patient’s medical records, a positive predictive value of 79% was found for the PE diagnosis. Post-PE patients with remaining dyspnea and/or previously known risk factors for CTEPH development were referred for blood sampling and levels of N-terminal (NT)-prohormone (pro) brain-type natriuretic peptide (BNP) were determined. Thereafter, they were referred to their local hospital for a pulmonary ventilation/perfusion (V/Q) scintigraphy and echocardiography. Approximately 45% of the V/Q-scans showed perfusion defects and 27 % of echocardiographies showed signs of pulmonary hypertension. In total, 24 cases of CTEPH were identified, resulting in a prevalence of 0.4 % (95 % confidence interval 0.2 %–0.6 %). Conclusion: An acute PE is a serious event, associated with decreased survival, multiple comorbidities, frequent dyspnea, and pathological investigational findings. The term CTEPD seems reasonable as it captures that this is a disease of the pulmonary vasculature, and that pharmacological and surgical interventions used for CTEPH may be useful. Regardless, proper follow-up after acute PE is essential for timely identification of patients in need of appropriate investigations and care.
