- BackgroundPatient-reported symptoms of acute myocardial infarction (MI) may be affected by recall bias depending on when and where symptoms are assessed.AimThe aim of this study was to gain an understanding of patients symptom description in more detail before and within 24 hours after a confirmed MI diagnosis.MethodsA convergent parallel mixed-methods design was used to examine symptoms described in calls between the tele-nurse and the patient compared with symptoms selected by the patient from a questionnaire less than 24 hours after hospital admission. Quantitative and qualitative data were analyzed separately and then merged into a final interpretation.ResultsThirty patients (median age, 67.5 years; 20 men) were included. Chest pain was the most commonly reported symptom in questionnaires (24/30). Likewise, in 19 of 30 calls, chest pain was the first complaint mentioned, usually described together with the symptom onset. Expressions used to describe symptom quality were pain, pressure, discomfort, ache, cramp, tension, and soreness. Associated symptoms commonly described were pain or numbness in the arms, cold sweat, dyspnea, weakness, and nausea. Bodily sensations, such as feeling unwell or weak, were also described. Fear and tiredness were described in calls significantly less often than reported in questionnaires (P = .01 and P = .02), whereas "other" symptoms were more often mentioned in calls compared with answers given in the questionnaire (P = .02). Some symptoms expressed in the calls were not listed in the questionnaire, which expands the understanding of acute MI symptoms. The results showed no major inconsistencies between datasets.ConclusionPatients MI symptom descriptions in tele-calls and those reported in questionnaires after diagnosis are comparable and convergent.

- The aim of the study was to investigate long-term patient consequences of cranial nerve injury (CNI) caused by carotid endarterectomy (CEA) in patients with identified CNI at the 30-day follow-up.Consecutive patients operated for symptomatic carotid artery stenosis 2015-2019 with a documented CNI at the 30-day follow-up after CEA were recruited to this cross-sectional survey. Telephone interviews were conducted >1 year after CEA utilizing survey instruments developed to uncover CNI symptoms. Patients graded their symptoms on a 4-point scale: 1) no symptoms; 2) mild symptoms; 3) moderate symptoms; and 4) severe symptoms.Altogether, 477 patients underwent CEA, of which 82 were diagnosed with CNI; 70/82 patients remained alive at the time for the survey and 68 patients completed the interview. The mean follow-up time was 3.7 years. Severe persistent CNI symptoms were reported in 2/68 (2.9%), moderate symptoms in 1/68 (1.5%) and mild symptoms in 14/68 (21%) whereas 51/68 patients (75%) reported no residual symptoms. When extrapolating these findings to all patients, approximately 4.4% reported persistent symptoms at the long-term follow-up and only 0.8% reported moderate or severe symptoms.The long-term consequences of CNI following CEA are benign in most patients, with a high rate of symptom resolution and a very low rate of persistent clinically significant symptoms.

- ObjectiveTo evaluate microvascular function in women with previous hypertensive disorders of pregnancy (HDP).DesignRetrospective population-based cohort study.SettingLinkoping, Sweden.PopulationWomen aged 50-65 years, participating in the Swedish CArdioPulmonary bioImage Study (SCAPIS) at one site (Linkoping) 2016-18, who underwent microcirculatory assessment (N = 1222).MethodsForearm skin comprehensive microcirculatory assessment was performed with a PeriFlux PF6000 EPOS (Enhanced Perfusion and Oxygen Saturation) system measuring oxygen saturation and total speed resolved perfusion. Obstetric records were reviewed to identify women with previous HDP. Data on cardiovascular risk factors, comorbidities, medication, lifestyle, anthropometric data, and biochemical analyses were obtained from SCAPIS. The microcirculatory data were compared between women with and without previous HDP.Main outcome measuresSkin microcirculatory oxygen saturation and total speed resolved perfusion at baseline and post-ischaemic peak.ResultsWomen with previous pre-eclampsia displayed impaired post-ischaemic peak oxygen saturation compared with women with normotensive pregnancies (88%, interquartile range [IQR] 84-89% vs 91%, IQR 87-94%, p = 0.001) 6-30 years after pregnancy. The difference remained after multivariable adjustment (& beta; -2.69, 95% CI -4.93 to -0.45).ConclusionsThe findings reveal microvascular dysfunction at long-term follow up in women with previous pre-eclampsia and strengthen the possible role of endothelial dysfunction as a link to the increased risk of cardiovascular disease in women with HDP.

- AIMS: A short time span from symptom onset to reperfusion is imperative in ST-segment elevation myocardial infarction (STEMI). The aim of this study was to determine factors associated with patient decision time for seeking care in STEMI, particularly how symptoms were experienced and affected patient response.METHODS AND RESULTS: A multicentre cross-sectional self-report survey study was completed at five Swedish hospitals representing geographic diversity. The 521 patients were divided into three groups based on their time to respond to symptoms: early (<20 min), intermediate (20-90 min), and late responders (>90 min). Only one out of five patients both responded early and called an ambulance within 20 min. Believing symptoms were cardiac in origin [odds ratio (OR) 2.60], male sex (OR 2.40), left anterior descending artery as culprit artery (OR 1.77), and bystanders calling an ambulance (OR 4.32) were factors associated with early response and correct action. Associated symptoms such as dyspnoea (OR 1.67) and weakness (OR 1.65) were associated with an early action (<20 min), while chest pain was not independently associated with response time. Cold sweat (OR 0.61) prevented late care-seeking behaviour as did a high symptom burden (OR 0.86).CONCLUSION: Misinterpretation of symptoms delays correct care-seeking behaviour because patient expectations may not be aligned with the experience when stricken by Myocardial infarction. Therefore, it is imperative to continuously enhance public awareness in correct symptom recognition and appropriate care-seeking behaviour and to make efforts to educate individuals at risk for STEMI as well as their next of kin.

No time to waste : Pre-hospital actions and time delays in patients with ST elevation myocardial infarction – temporal trends and prognostic impact on short- and long-term survival
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: In ST-elevation myocardial infarction (STEMI) patients, a rapid diagnosis is imperative to reduce total ischaemic time minimizing risk for heart failure, serious arrhythmias, or death. Prehospital context is complex, and the patient delay constitute major part of the pre-hospital phase. Patient delay has been prone hard to impact but the system delay has had major transformation during the years. Aim: The overall aim was to explore pre-hospital actions and time delays in STEMI patients, investigating temporal trends and estimate prognostic impact on short- and long-term survival. Methods: Study I, was a multicentre survey study, exploring decisions, and actions in relation to the choice of first medical contact (FMC). Study II was a sub-study to the multicentre survey, exploring the interaction between tele nurses and callers in authentic calls when the caller with an evolving myocardial infarction (MI) chose to call Swedish health care direct (SHD) as FMC. Study III, was based on the same database as study I, exploring early (< 20 minutes) and late (> 90 minutes) response from symptom onset in STEMI patients. Study IV, was based on SWEDEHEART-registry, investigating temporal trends in pre-specified risk groups for pro-longed pre-hospital delay times (PHDT), estimating cumulative survival in short and long term stratified in six different PHDT groups. Results: Study I, only half of the patients’ contacted emergency medical services (EMS) as their FMC. Choice of FMC prolonged time to diagnosis in relation of calling EMS. Choosing SHD pro-longed delay to diagnosis with 38 minutes. Study II, four interactions were found between tele-nurses and callers, reasoning, distinct, irrational, and indecisive, and type of interaction could lead or mislead the call moving progressively forward or not. Study III, bystanders calling EMS, men, intensive and alarming symptoms such as dyspnoea and weakness and to interpret symptoms attributed from the heart was associated with a rapid action calling an ambulance within 20 minutes, which was performed by one of five patients. Study IV, trend curves for median PHDT was hump shaped for the 20 years studied. Women, older age, and patients with diabetes had consistent pro-longed PHDT, except for the oldest patients (> 80 years). PHDT was an independent risk for short- and long-term survival. Patients with the shortest PHDT 0-1 hour had the highest mortality up to five days. In five-year follow up this group accompanied with the group within 1-2 hours had highest estimated survival. Conclusion: Pre-hospital delay is an independent predictor of short- and long-term survival. To interpret symptom correctly and knowledge in how to act, calling an ambulance rapidly, impact time to diagnosis and diminish time delays. Pre-hospital delay merits further attention regarding future interventions.

Tidskriftsartikel (refereegranskat)abstract
- Immunological control of residual leukemia cells is thought to occur in patients with chronic myeloid leukemia (CML) that maintain treatment-free remission (TFR) following tyrosine kinase inhibitor (TKI) discontinuation. To study this, we analyzed 55 single-cell RNA and T cell receptor (TCR) sequenced samples (scRNA+TCRαβ-seq) from patients with CML (n = 13, N = 25), other cancers (n = 28), and healthy (n = 7). The high number and active phenotype of natural killer (NK) cells in CML separated them from healthy and other cancers. Most NK cells in CML belonged to the active CD56dim cluster with high expression of GZMA/B, PRF1, CCL3/4, and IFNG, with interactions with leukemic cells via inhibitory LGALS9-TIM3 and PVR-TIGIT interactions. Accordingly, upregulation of LGALS9 was observed in CML target cells and TIM3 in NK cells when co-cultured together. Additionally, we created a classifier to identify TCRs targeting leukemia-associated antigen PR1 and quantified anti-PR1 T cells in 90 CML and 786 healthy TCRβ-sequenced samples. Anti-PR1 T cells were more prevalent in CML, enriched in bone marrow samples, and enriched in the mature, cytotoxic CD8+TEMRA cluster, especially in a patient maintaining TFR. Our results highlight the role of NK cells and anti-PR1 T cells in anti-leukemic immune responses in CML.

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- There is limited knowledge about PhD students’ backgrounds and how these backgrounds affect their research, particularly in sport sciences. Therefore, this study aims to contribute with knowledge about the backgrounds of sport sciences PhD students by investigating whether their backgrounds affect both becoming PhD students and how they conduct their research. Importantly, the study descriptively presents PhD students’ stories about their backgrounds and explores whether there are general themes in these stories. Guided by an auto-monographic approach, we asked PhD students at the Department of Sport sciences at Malmö University to “describe whether my background influenced me to become a doctoral student in sport sciences and whether my background affects my research.” Although the PhD students’ narratives include many perspectives and experiences, they also raise questions about the diversity of the group—they reveal a lack of cultural and socioeconomic diversity in the group. As a result, this article raises questions about whether “enough” is being done, by Malmö University and Department of Sport Sciences, to attract PhD students with different backgrounds.

Two or more ischaemic events within seven days before carotid endarterectomy increases the risk of peri-operative stroke or death
- 2024

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of this study was to determine how many pre-operative ischaemic events occurring within a specific timeframe before carotid endarterectomy (CEA) are needed to increase the peri-operative 30 day risk of stroke or death.Methods: This was a secondary exploratory analysis based on pooled data from three observational studies sourced from a single centre. Patients with recently symptomatic conventional ≥ 50% carotid stenosis were included. The principal analysis was limited to patients presenting with stroke or transient ischaemic attack (TIA). The primary outcome was 30 day risk of peri-operative stroke or death. Whether one, two, three, or four or more ipsilateral pre-operative ischaemic events within three, seven, 14, or 30 days before CEA were associated with the primary outcome was assessed.Results: The study included 382 patients who underwent CEA with symptomatic conventional ≥ 50% carotid stenosis with stroke or TIA as the presenting event. Mean patient age ± standard deviation was 72 ± 7 years, 117 (30.6%) were female, and 5% were treated with dual antiplatelet therapy. The primary outcome occurred in 21 patients (5.5%). Two or more events within 7 days before CEA was the most discriminative definition of repeated events, with a 14.3% (8/56) risk of the primary outcome. Those who fell outside this definition of two or more events within seven days before CEA had a 4.0% (13/326; p = .006) risk of experiencing the primary outcome (adjusted odds ratio 4.1, 95% confidence interval 1.6 – 10.5). Several alternative definitions were assessed, but patients with two or more events within seven days before CEA and negative for these alternatives still had a > 10% risk of the primary outcome.Conclusion: Two or more ipsilateral ischaemic events within seven days before CEA is associated with an increased risk of peri-operative stroke or death in cases with symptomatic conventional ≥ 50% carotid stenosis and TIA or stroke as the presenting event. Studies assessing whether delayed or immediate CEA is preferable for this patient group are warranted.
