- OBJECTIVE: Most reports on the declining incidence of myocardial infarction (MI) during the COVID-19 have either been anecdotal, survey results or geographically limited to areas with lockdowns. We examined the incidence of MI during the COVID-19 pandemic in Sweden, which has remained an open society with a different public health approach fighting COVID-19.METHODS: We assessed the incidence rate (IR) as well as the incidence rate ratios (IRRs) of all MI referred for coronary angiography in Sweden using the nationwide Swedish Coronary Angiography and Angioplasty Registry (SCAAR), during the COVID-19 pandemic in Sweden (1 March 2020-7 May 2020) in relation to the same days 2015-2019.RESULTS: A total of 2443 MIs were referred for coronary angiography during the COVID-19 pandemic resulting in an IR 36 MIs/day (204 MIs/100 000 per year) compared with 15 213 MIs during the reference period with an IR of 45 MIs/day (254 MIs/100 000 per year) resulting in IRR of 0.80, 95% CI (0.74 to 0.86), p<0.001. Results were consistent in all investigated patient subgroups, indicating no change in patient category seeking cardiac care. Kaplan-Meier event rates for 7-day case fatality were 439 (2.3%) compared with 37 (2.9%) (HR: 0.81, 95% CI (0.58 to 1.13), p=0.21). Time to percutaneous coronary intervention (PCI) was shorter during the pandemic and PCI was equally performed, indicating no change in quality of care during the pandemic.CONCLUSION: The COVID-19 pandemic has significantly reduced the incidence of MI referred for invasive treatment strategy. No differences in overall short-term case fatality or quality of care indicators were observed.

- INTRODUCTION: A substantial number of patients with coronary artery disease undergo cardiac surgery within five days of discontinuing anti-platelet treatment with aspirin and clopidogrel. The aims of this study were to describe the degree of platelet inhibition in patients with dual anti-platelet treatment scheduled for coronary artery bypass graft (CABG) surgery and to investigate whether the measured platelet inhibition correlated to intra- and postoperative risk for bleeding and transfusion requirements. MATERIAL AND METHODS: Sixty patients were included. Platelet inhibition was analysed with flow cytometry including phosphorylation status of the vasodilator-stimulated phosphoprotein (VASP-assay) and two bed-side analyzers, VerifyNow-System and PlateletMapping, a modified thrombelastograph. All 60 patients were analysed with VerifyNow and PlateletMapping, and 48 were analysed with flow cytometry and VASP-assay. RESULTS: There was a correlation between the ADP-receptor inhibition as measured by VASP-assay and VerifyNowP2Y(12) (r = -0.29, p<0.05), and between VASP-assay and the expression of P-selectin (r = 0.29, p<0.05) as measured by flow cytometry when platelets were stimulated with 5 microM ADP. VerifyNowP2Y(12) was the only measurement of platelet inhibition correlated to total blood loss (Spearman r = 0.29, p=0.03) and red blood cell transfusion (Spearman r = 0.43, p<0.01) requirements, although this might be confounded by aprotinin treatment. CONCLUSION: We found a modest agreement between the methods for preoperative platelet inhibition, though not for PlateletMapping-MA(ADP). There was a correlation between preoperative platelet inhibition measured by VerifyNowP2Y(12) and surgical blood loss or transfusion requirements. However, for the individual patient, preoperative use of VerifyNowP2Y(12) as an instrument to decide bleeding and transfusion risk does not seem helpful.

Journal article (peer-reviewed)abstract
- INTRODUCTION: Addition of clopidogrel to patients treated with ASA has been shown to decrease the incidence of in-stent thrombosis after percutaneous coronary interventions. However, it has also been reported that up to 30% of patients do not achieve adequate platelet inhibition from standard dosages of ASA and clopidogrel. There is a demand for reliable methods to measure the individual platelet inhibiting effect of this combination therapy. MATERIALS AND METHODS: The primary aim of the present investigation was to compare three methods for evaluation of the platelet inhibiting effect of a clopidogrel bolus dose in patients on long-term acetylsalicylic acid treatment. Thirty patients presenting for coronary angiography/PCI were included. Two patients were excluded due to technical problems. All patients were on 75-100 mg ASA/day for at least 8 days. Blood samples were analysed before and 16 h after a 300 mg clopidogrel bolus dose. The platelet inhibiting effect was measured with (1) Whole blood flow cytometry (17 patients); (2) a bed-side test, Platelet Mapping assay for the thrombelastograph (28 patients); and (3) PFA (Platelet function analyser) -100 (26 patients). RESULTS: With flow cytometry, the percentage of platelets expressing P-selectin (p=0.03) on their surface decreased significantly after the bolus dose of clopidogrel. There was also a reduction of platelets binding fibrinogen when stimulated with ADP. A significantly (p=0.002) increased platelet inhibition could also be demonstrated with Platelet Mapping. PFA-100 could not measure any significant platelet inhibiting effect of clopidogrel. CONCLUSION: A significant platelet inhibition could be demonstrated with flow cytometry and the Platelet Mapping assay, but not with PFA-100. However, levels of response for the individual patient with these three methods were inconsistent. Further studies are needed to evaluate how the results correlate to the clinical risk of thrombosis and bleeding.

The separation and identification of parasite eggs from horse feces

Conference paper (peer-reviewed)abstract
- Freely grazing horses are at risk of infection by parasites such as Parascaris equorum (roundworm), Strongylus spp. (large bloodworms), Cyathostomes (small bloodworms), and Anoplochephala perfoliata (tapeworms). Mixed infections are common and diagnosis is based on demonstrations of eggs in feces followed by identification of larvae after fecal culture. Drug resistance is a growing problem, not least because treatments tend to be cheaper than diagnosis and “just in case” treatments common. There is a need for improved methods that are easy to use, rapid and cheap. Furthermore, a successful approach may find use with other livestock such as ruminants and pigs.

TNFR1, TNFR2, neutrophil gelatinase-associated lipocalin and heparin binding protein in identifying sepsis and predicting outcome in an intensive care cohort
- 2020

Journal article (peer-reviewed)abstract
- To date no biomarkers can aid diagnosing sepsis with adequate accuracy. We set out to assess the ability of Tumor necrosis factor receptor (TNFR) 1 and 2, Neutrophil gelatinase-associated lipocalin (NGAL) and Heparin binding protein (HBP) to discriminate sepsis from non-infected critically ill patients in a large ICU cohort, and to evaluate their value to predict mortality at 30 days. Adult patients admitted to the ICU with an arterial catheter were included. Clinical data and blood samples were prospectively recorded daily. Diagnoses were set retrospectively. Descriptive statistics and logistic regression models were used. NGAL, TNFR1 and TNFR2 were higher in sepsis patients compared to other diagnoses, as well as in non-survivors compared to survivors. In addition, these biomarkers increased with increasing stages of acute kidney injury. TNFR1 and TNFR2 performed similarly to NGAL and CRP in identifying sepsis patients, but they performed better than CRP in predicting 30-day mortality in this ICU cohort. Thus, TNFR1 and TNFR2 may be particularly useful in identifying high risk sepsis patients and facilitate relevant health care actions in this group of sepsis patients.

Journal article (peer-reviewed)abstract
- Pornography is one of the most sought-after topics on the Internet, and is easily available for anyone, including children and adolescents. At youth centres, nurse-midwives have noticed that young people have different kinds of questions about sexual practices compared with a few years ago. The aim of this study was to gain an understanding of thoughts and reflections about pornography consumption, and its possible influence on sexual practices, among young women and men. The staff at a youth centre in a city in central Sweden asked the visitors if they had seen pornography and if they wanted to be interviewed about their experiences. Ten young women and eight men, aged 16-23 years, participated. In-depth interviews were performed and open-ended questions about pornography and sexuality were posed. The interviews were tape-recorded and transcribed verbatim. Data were analysed according to grounded theory. The core category 'Living with the current sexual norm' depicted how pornography created sexual expectations and demands, for instance, to perform certain sexual acts. The informants expressed contradictory feelings towards pornography and felt that sexuality was separated from intimacy. A moral attitude was described and examples of stereotypic gender roles were given. To deal with the current sexual norm, informants had different individual handling strategies and attitudes to pornography, namely liberal, normalization, distance, feminist or conservative. Limitations of this study were the small sample size and that results from a qualitative research study cannot be generalized. The results contribute to an understanding of how pornographic material can influence young peoples' thoughts, reflections and sexual behaviour. This indicates the importance, for personnel at youth centres and schools, to discuss sexual behaviour and how sexuality is portrayed in pornographic material with young people.

Journal article (peer-reviewed)abstract
- Sepsis is the most frequent cause of death in the intensive care unit (ICU). A rapid and correct diagnosis and initiation of therapy is crucial for improving patient outcomes. The aim of this study was to compare the performance of calprotectin with the more widely used sepsis biomarker procalcitonin (PCT) in ICU patients. The performance of calprotectin and PCT as sepsis and prognostic markers for 30-d mortality was compared in a prospective, observational study in an eight-bed ICU. We investigated concentrations of the biomarkers in plasma collected at admission from all ICU patients admitted during a year (2012-2013, n = 271) together with simplified acute physiology 3 scores (SAPS3) and sequential organ failure assessment (SOFA) scores. The receiver operating characteristic (ROC) analysis showed a higher area under the curve (AUC) value for calprotectin (0.79) than for PCT (0.49) when used as a sepsis marker. The calprotectin concentrations at admission were higher in non-survivors than in survivors at day 30. In our study, calprotectin was superior to PCT for distinguishing between ICU patients with sepsis and non-sepsis patients. Calprotectin also had higher predictive ability regarding 30-d mortality.
