- AIM: To describe health status and psychological distress among in-hospital cardiac arrest (IHCA) survivors in relation to gender.METHODS: This national register study consists of data from follow-up registration of IHCA survivors 3-6 months post cardiac arrest (CA) in Sweden. A questionnaire was sent to the survivors, including measurements of health status (EQ-5D-5L) and psychological distress (HADS).RESULTS: Between 2013 and 2015, 594 IHCA survivors were included in the study. The median values for EQ-5D-5L index and EQ VAS among survivors were 0.78 (q1-q3=0.67-0.86) and 70 (q1-q3=50-80) respectively. The values were significantly lower (p<0.001) in women compared to men. In addition, women reported more problems than men in all dimensions of EQ-5D-5L, except self-care. A majority of the respondents reported no problems with anxiety (85.4%) and/or symptoms of depression (87.0%). Women reported significantly more problems with anxiety (p<0.001) and symptoms of depression (p<0.001) compared to men. Gender was significantly associated with poorer health status and more psychological distress. No interaction effects for gender and age were found.CONCLUSIONS: Although the majority of survivors reported acceptable health status and no psychological distress, a substantial proportion reported severe problems. Women reported worse health status and more psychological distress compared to men. Therefore, a higher proportion of women may be in need of support. Health care professionals should make efforts to identify health problems among survivors and offer individualised support when needed.

- The aim of this study was to examine platelet function after coronary artery bypass grafting (CABG) with and without the use of extracorporeal circulation (ECC). Sixteen male patients scheduled for CABG with (n = 8) and without (n = 8) ECC were included in the study. Platelet retention, as measured with a glass-bead retention test, was examined daily during the first postoperative week. Von Willebrand factor (vWF), ristocetin co-factor (Rcof) and prothrombin fragment (PF 1 + 2) were analyzed the day after the operation. We found a significant increase (p < 0.0001) in platelet retention during the first postoperative week after CABG. There was a tendency (not statistically significant) towards a more pronounced increase in the group operated on without ECC. This increase occurred despite the fact that all patients were treated with aspirin (75 mg daily) from the first postoperative day. The median time to maximal postoperative platelet retention was 2 days. In 3 patients platelet retention increased to more than 6 times the basal level.

Prehospital Diagnosis and Oxygen Treatment in ST Elevation Myocardial Infarction
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- IntroductionPaper I: An Artificial Neural Network (ANN) was constructed to identify ST Elevation Myocardial Infarction (STEMI) and predict the need for Percutaneous Coronary Intervention (PCI). Paper II, III and IV: Studies suggest that O2 therapy may be harmful in STEMI patients. We therefore conducted the SOCCER study to evaluate the effects of O2 therapy in STEMI patients.MethodsPaper I: 560 ambulance ECGs sent to the Cardiac Care Unit (CCU), was together with the CCU physicians interpretation and decision of conducting an acute PCI or not collected, and compared with the interpretation and PCI decision of the ANN. Paper II, III, IV: Normoxic (≥94%) STEMI patients accepted for acute PCI were in the ambulance randomized to standard care with 10 L/min O2 or room air. A subset of the patients underwent echocardiography for determination of the Left Ventricular Ejection Fraction (LVEF) and the Wall Motion Score Index (WMSI). All patients had a Cardiac Magnetic Resonance Imaging (CMRI) to evaluate Myocardial area at Risk (MaR), Infarct Size (IS) and Myocardial Salvage Index (MSI).ResultsPaper I: The area under the ANN’s receiver operating characteristics curve for STEMI detection as well as predicting the need of acute PCI were very good.Paper II, III, IV: No significant differences could be shown in discussing MaR, MSI or IS between the O2 group (n=46) and the air group (n=49). Neither could any differences be shown for LVEF and WMSI at the index visit as well after six months between the O2 group (n=46) and the air group (n=41)ConclusionsPaper I: The results indicate that the number of ECGs sent to the CCU could be reduced with 2/3 as the ANN would safely identify ECGs not being STEMI.Paper II, III, IV: The results suggest that it is safe to withhold O2 therapy in normoxic, stable STEMI patients.

Controversial significance of early S100B levels after cardiac surgery

Tidskriftsartikel (refereegranskat)abstract
- BackgroundThe brain-derived protein S100B has been shown to be a useful marker of brain injury of different etiologies. Cognitive dysfunction after cardiac surgery using cardiopulmonary bypass has been reported to occur in up to 70% of patients. In this study we tried to evaluate S100B as a marker for cognitive dysfunction after coronary bypass surgery with cardiopulmonary bypass in a model where the inflow of S100B from shed mediastinal blood was corrected for.Methods56 patients scheduled for coronary artery bypass grafting underwent prospective neuropsychological testing. The test scores were standardized and an impairment index was constructed. S100B was sampled at the end of surgery, hourly for the first 6 hours, and then 8, 10, 15, 24 and 48 hours after surgery. None of the patients received autotransfusion.ResultsIn simple linear analysis, no significant relation was found between S100B levels and neuropsychological outcome. In a backwards stepwise regression analysis the three variables, S100B levels at the end of cardiopulmonary bypass, S100B levels 1 hour later and the age of the patients were found to explain part of the neuropsychological deterioration (r = 0.49, p < 0.005).ConclusionsIn this study we found that S100B levels 1 hour after surgery seem to be the most informative. Our attempt to control the increased levels of S100B caused by contamination from the surgical field did not yield different results. We conclude that the clinical value of S100B as a predictive measurement of postoperative cognitive dysfunction after cardiac surgery is limited.

- Aim Our aim was to evaluate the risk of bacterial meningitis, bacteremia, and urinary tract infection (UTI) in infants <= 60 days who presented to paediatric emergency departments (PEDs) after having fever at home. We also investigated any differences between infants who were afebrile or febrile on presentation. Methods This was a multicenter retrospective study of infants <= 60 days presented to four Swedish PEDs during 2014-2020 with reported fever at home. We used relative risks (RR) to compare the prevalence of UTI, bacteremia, and bacterial meningitis between the infants who were afebrile and the infants who were still febrile when they presented to the PED. Results The cohort comprised 1926 infants, and 702 (36%) were afebrile on presentation. The prevalence of UTI in the afebrile and febrile infants was 6.1% [95% confidence interval (CI) 4.5-8.2] versus 14.2% (95% CI 12.3-16.2), corresponding to an RR of 0.43 (95% CI 0.31-0.59). In infants <= 28 days, the RR for meningitis was 1.05 (95% CI 0.18-6.23) for afebrile versus febrile infants. Five times more febrile infants underwent a lumbar puncture. Conclusion Infants who were afebrile on presentation underwent fewer lumbar punctures, but they had similar rates of bacterial meningitis to febrile infants. Different management approaches are not justified.

- Objective. To study the kinetics of lipid micro-emboli during cardiac surgery. Design. Eleven pigs were studied. Seven of these were put on extracorporeal circulation. A shed blood phantom consisted of blood, saline and radioactive triolein was added to the circuit. Both venous and arterial blood samples were taken at short intervals. Four animals were used to study renal kinetics without extracorporeal circulation. The same kind of shed blood phantom was infused into the ascending aorta. Samples were taken from the renal artery and vein. All samples were analyzed for radioactivity by scintillation counting. Results. A median 130-fold increase in radioactivity was seen in the blood and was quickly eliminated. Systemic first-pass wedging was found to be 62%. The first-pass elimination in the kidney was 77%. No radioactivity was found in urine. Conclusions. This study shows that the turnover of lipid micro-emboli is fast, and that the majority of the emboli are trapped on their first passage through the capillary system. No evidence was found of a renal excretion of these lipid emboli.

- We describe a 23-year-old male patient who presented with spontaneous intermittent and increasing attacks of severe, left-sided thunderclap headache combined with rapidly progressive muscle weakness and dysphasia, including gradual loss of consciousness. Subsequent CT, MRI and DSA showed progressive brain ischaemia and oedema within the left cerebral hemisphere with strict ipsilateral segmental arterial vasoconstriction. Despite extensive medical care, including steroids, the patient deteriorated rapidly. However, the clinical course changed dramatically within 15 h after the start of an intravenous infusion of prostacyclin at a dose of 0.9 ng/kg/min, with an almost complete recovery of consciousness and speech. In addition the pathophysiological alterations seen on magnetic resonance (imaging and digital) subtraction angiography including diffusion-weighted imaging and apparent diffusion coefficient maps shortly before prostacyclin treatment were clearly reduced when the patient was examined 3-4 days later and he continued to recover thereafter. Although not fully compatible, our case had several clinical characteristics and radiological findings reminiscent of those of the 'segmental reversible vasoconstriction syndrome', sometimes called the Call-Fleming syndrome.
