Frontiers in Cardiovascular Medicine 2024Atrial fibrillation (AF) is a prevalent issue among critically ill patients, and the availability of effective treatment strategies for AF is limited.
BACKGROUND
Atrial fibrillation (AF) is a prevalent issue among critically ill patients, and the availability of effective treatment strategies for AF is limited.
AIM
The objective of this study was to evaluate the mortality rate associated with AF in critically ill patients who were either aspirin or non-aspirin users.
METHODS
This cohort study incorporated critically ill patients with AF from the Medical Information Mart for Intensive Care database. The study compared incidences of 28-day mortality, 90-day mortality, and 1-year mortality between patients with and without aspirin prescriptions. To assess the association between aspirin and the endpoints, Kaplan-Meier analysis and Cox proportional hazards regression analyses were conducted.
RESULTS
In this study, a total of 13,330 critically ill patients with atrial fibrillation (AF) were included, of which 4,421 and 8,909 patients were categorized as aspirin and non-aspirin users, respectively. The 28-day, 90-day, and 1-year mortality rates were found to be 17.5% (2,330/13,330), 23.9% (3,180/13,330), and 32.9% (4,379/13,330), respectively. The results of a fully-adjusted Cox proportional hazard model indicated that aspirin use was negatively associated with the risk of death after adjusting for confounding factors (28-day mortality, HR 0.64, 95% CI 0.55-0.74; 90-day mortality, HR 0.65, 95% CI 0.58-0.74; 1-year mortality, HR 0.67, 95%CI 0.6∼0.74). The results of the subgroup analysis indicate a more robust correlation, specifically among patients under the age of 65 and those without a history of congestive heart failure or myocardial infarction.
CONCLUSIONS
The utilization of aspirin may exhibit a correlation with a reduction in risk-adjusted mortality from all causes in critically ill patients diagnosed with atrial fibrillation. However, additional randomized controlled trials are necessary to elucidate and confirm this potential association.

UNLABELLED
Coronavirus disease 2019 (COVID-19) is associated with an increased risk of thromboembolic events. However, there are few reports on multiple thromboembolic events in young patients with COVID-19. Herein, we report a case of multiple visceral arterial embolisms secondary to acute myocardial infarction in a young patient with COVID-19. A 36-year-old male developed sudden chest pain after being diagnosed with COVID-19. Emergency coronary angiography revealed total occlusion of the right coronary artery, and the patient underwent a subsequent emergency percutaneous coronary intervention (PCI) which achieved successful recanalization. The patient was administered a loading dose and a subsequent maintenance dose of aspirin and prasugrel and a continuous intravenous infusion of unfractionated heparin at 10,000 units per day. Echocardiography detected a left ventricular apical thrombus 3 days after PCI; a loading dose of warfarin was administered and promptly reached the therapeutic range. However, the patient developed superior mesenteric artery embolism and renal infarction on the 12th day after PCI. COVID-19 was considered to play a role in the thromboembolic events observed in this patient. This case highlights the need for individualized antithrombotic regimens when managing patients with COVID-19 who develop acute myocardial infarction.
LEARNING OBJECTIVE
Reportedly, coronavirus disease 2019 (COVID-19) is associated with an increased risk of venous and arterial thromboembolic events. However, few reports have described multiple thromboembolic events in younger patients with COVID-19. This case report describes arterial thromboembolism secondary to acute myocardial infection (AMI) in a patient with COVID-19. It highlights the need for individualized antithrombotic regimens when managing patients with COVID-19 who develop AMI.

This study aimed to investigate the molecular mechanisms underlying the protective effects of cyclooxygenase (cox) inhibitors against myocardial hypertrophy.Rat H9c2 cardiomyocytes were induced by mechanical stretching. SD rats underwent transverse aortic constriction to induce pressure overload myocardial hypertrophy. Rats were subjected to echocardiography and tail arterial pressure in 12W. qPCR and western blot were used to detect the expression of Notch-related signaling. The inflammatory factors were tested by ELISA in serum, heart tissue, and cell culture supernatant.Compared with control, levels of pro-inflammatory cytokines IL-6, TNF-α, and IL-1β were increased and anti-inflammatory cytokine IL-10 was reduced in myocardial tissues and serum of rat models. Levels of Notch1 and Hes1 were reduced in myocardial tissues. However, cox inhibitor treatment (aspirin and celecoxib), the improvement of exacerbated myocardial hypertrophy, fibrosis, dysfunction, and inflammation was parallel to the activation of Notch1/Hes1 pathway. Moreover, in vitro experiments showed that, in cardiomyocyte H9c2 cells, application of ~20% mechanical stretching activated inflammatory mediators (IL-6, TNF-α, and IL-1β) and hypertrophic markers (ANP and BNP). Moreover, expression levels of Notch1 and Hes1 were decreased. These changes were effectively alleviated by aspirin and celecoxib.Cox inhibitors may protect heart from hypertrophy and inflammation possibly via the Notch1/Hes1 signaling pathway.

Aspirin is widely used for both primary and secondary prevention of panvascular diseases, such as stroke and coronary heart disease (CHD). The optimal balance between reducing panvascular disease events and the potential increase in bleeding risk remains unclear. This study aimed to develop a predictive model specifically designed to assess bleeding risk in individuals using aspirin. A total of 58,415 individuals treated with aspirin were included in this study. Detailed data regarding patient demographics, clinical characteristics, comorbidities, medical history, and laboratory test results were collected from the Affiliated Dongyang Hospital of Wenzhou Medical University. The patients were randomly divided into two groups at a ratio of 7:3. The larger group was used for model development, while the smaller group was used for internal validation. To develop the prediction model, we employed least absolute shrinkage and selection operator (LASSO) regression followed by multivariate logistic regression. The performance of the model was assessed through metrics such as the area under the receiver operating characteristic (ROC) curve (AUC), calibration curves, and decision curve analysis (DCA). The LASSO-derived model employed in this study incorporated six variables, namely, sex, operation, previous bleeding, hemoglobin, platelet count, and cerebral infarction. It demonstrated excellent performance at predicting bleeding risk among aspirin users, with a high AUC of 0.866 (95% CI 0.857-0.874) in the training dataset and 0.861 (95% CI 0.848-0.875) in the test dataset. At a cutoff value of 0.047, the model achieved moderate sensitivity (83.0%) and specificity (73.9%). The calibration curve analysis revealed that the nomogram closely approximated the ideal curve, indicating good calibration. The DCA curve demonstrated a favorable clinical net benefit associated with the nomogram model. Our developed LASSO-derived predictive model has potential as an alternative tool for predicting bleeding in clinical settings.

INTRODUCTION
Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterised by thrombosis and pregnancy morbidity in the presence of antiphospholipid antibodies (aPL). Our study aims to study the clinical and laboratory characteristics, treatment strategies and outcomes of APS patients retrospectively.
MATERIALS AND METHODS
A retrospective review of all APS patients treated in Rheumatology Unit, Hospital Pulau Pinang between October 2021 and October 2022 was conducted.
RESULTS
A total of 53 APS patients (age 42.4±13.9 years) including 22 (41.5%) primary and 31 (58.5%) secondary APS patients were identified. Thrombosis was the most common clinical manifestation (51/53; 96.2%) followed by pregnancy morbidity (15/45; 33.3%). For other clinical manifestations, aPL-associated thrombocytopenia was the most frequently observed manifestation (26.4%) followed by autoimmune haemolytic anaemia (18.9%). Lupus anticoagulant (LA) (88.7%) was the most commonly found aPL followed by anticardiolipin antibody (aCL) (50.9%) and anti-beta 2 glycoprotein 1 antibody (B2GP1) (30.2%). 10 (18.9%) patients tested positive for all three aPL. The majority of our patients (86.8%) receive warfarin as anticoagulation therapy while the remaining receive aspirin or direct oral anticoagulants.
CONCLUSION
Our population cohort demonstrated a high incidence of pregnancy morbidities and a similar incidence of thrombotic events compared to other population cohorts in both Asian and the European countries.

Meta-Analysis
OBJECTIVE
Tension-type headache is the most common type of primary headache and results in a huge socioeconomic burden. This network meta-analysis (NMA) aimed to compare the efficacy and safety of simple analgesics for the treatment of episodic tension-type headache (ETTH) in adults.
METHODS
We searched the Cochrane Library, PubMed, Web of Science, Embase, Chinese BioMedical Literature database and International Clinical Trials Registry Platform databases for eligible randomized clinical trials reporting the efficacy and/or safety of simple analgesics. A Bayesian NMA was performed to compare relative efficacy and safety. The surface under the cumulative ranking curve (SUCRA) was calculated to rank interventions. PROSPERO registration number: CRD42018090554.
RESULTS
We highlighted six studies including 3507 patients. For the 2 h pain-free rate, the SUCRA ranking was ibuprofen > diclofenac-K > ketoprofen > acetaminophen > naproxen > placebo. All drugs except naproxen reported a higher 2 h pain-free rate than placebo, with a risk ratio (RR) of 2.86 (95% credible interval, CrI: 1.62-5.42) for ibuprofen and 2.61 (1.53-4.88) for diclofenac-K. For adverse events rate, the SUCRA ranking was: metamizol > diclofenac-K > ibuprofen > lumiracoxib > placebo > aspirin > acetaminophen > naproxen > ketoprofen. The adverse event rates of all analgesics were no higher than those of placebo, except for ketoprofen. Moreover, all drugs were superior to placebo in the global assessment of efficacy. In particular, the RR of lumiracoxib was 2.47 (1.57-4.57). Global heterogeneity between the studies was low.
CONCLUSIONS
Simple analgesics are considered more effective and safe as a placebo for ETTH in adults. Our results suggest that ibuprofen and diclofenac-K may be the two best treatment options for patients with ETTH from a comprehensive point of view (both high-quality evidence).

Turkish Journal of Medical Sciences 2023To investigate the effects of acetylsalicylic acid (ASA) and the use of ultrasound elastography on testicular torsion.
BACKGROUND/AIM
To investigate the effects of acetylsalicylic acid (ASA) and the use of ultrasound elastography on testicular torsion.
MATERIALS AND METHODS
Herein, 6 equal groups of rats were formed (n: 48): control group, sham group, torsion/detorsion (T/D)-1 h group, T/D-1 h + ASA group, T/D-8 h group, and T/D-8 h + ASA group. Testicular torsion was created by rotating the left testis 720° clockwise. At 30 min before torsion, 100 mg/kg of ASA was injected intraperitoneally. Elastography was performed at 8 and 24 h. After orchiectomy, specimens were collected for histopathological evaluation.
RESULTS
When comparing the left testicular volume (LV) parameters obtained from the elastography applied at 8 h, significant differences were observed between the following group pairs: the sham and T/D-8 h groups, T/D-1 h and T/D-8 h groups, and T/D-1 h + ASA and T/D-8 h groups (p = 0.004, p = 0.023, and p = 0.026, respectively). The mean LVS (velocity) (stiffness assessment) of the groups was similar at 8 h. When comparing the LV parameters at 24 h, significant differences were found between the T/D-1 h and T/D-8 h groups and between the T/D-8 h and T/D-8 h + ASA groups (p = 0.008 and p = 0.004, respectively). For the LVS mean values at 24 h, significant differences were found between the control and sham groups, sham and T/D-1 h groups, sham and T/D-8 h groups, and sham and T/D-8 h + ASA groups (p = 0.009, p = 0.021, p = 0.027, and p = 0.009, respectively).Histopathological evaluation showed a decrease in the morphological grades and an increase in the mean testicular injury scores in the T/D-1 h + ASA group compared to the T/D-1 h group. The T/D-8 h + ASA group had a higher morphological grade than the T/D-8 h group, whereas their mean testicular injury scores were similar.
CONCLUSION
ASA treatment for testicular torsion was shown to be ineffective. Elastography can be a complementary method to Doppler ultrasonography in the diagnosis of testicular torsion and can guide surgeons in their approach to surgery.

BACKGROUND
Assessment of platelet function is key in diagnosing bleeding disorders and evaluating antiplatelet drug efficacy. However, there is a prevailing "one-size-fits-all" approach in the interpretation of measures of platelet reactivity, with arbitrary cutoffs often derived from healthy volunteer responses.
OBJECTIVES
Our aim was to compare well-used platelet reactivity assays.
METHODS
Blood and platelet-rich plasma obtained from the Framingham Heart Study ( = 3429) were assayed using a range of agonists in 5 platelet assays: light transmission aggregometry, Optimul aggregometry, Multiplate impedance aggregometry (Roche Diagnostics), Total Thrombus-Formation Analysis System, and flow cytometry. Using linear mixed-effect models, we determined the contribution of preanalytical and technical factors that modulated platelet reactivity traits.
RESULTS
A strong intra-assay correlation of platelet traits was seen in all assays, particularly Multiplate velocity ( = 0.740; ristocetin vs arachidonic acid). In contrast, only moderate interassay correlations were observed ( = 0.375; adenosine diphosphate Optimul E vs light transmission aggregometry large area under the curve). As expected, antiplatelet drugs strongly reduced platelet responses, with aspirin use primarily targeting arachidonic acid-induced aggregation, and explained substantial variance (β = -1.735; = 4.59 × 10; variance proportion = 46.2%) and P2Y antagonists blocking adenosine diphosphate responses (β = -1.612; = 6.75 × 10; variance proportion = 2.1%). Notably, female sex and older age were associated with enhanced platelet reactivity. Fasting status and deviations from standard venipuncture practices did not alter platelet reactivity significantly. Finally, the agonist batch, phlebotomist, and assay technician (more so for assays that require additional sample manipulation) had a moderate to large effect on measured platelet reactivity.
CONCLUSION
Caution must be exercised when extrapolating findings between assays, and the use of standard ranges must be medication-specific and sex-specific at a minimum. Researchers should also consider preanalytical and technical variables when designing experiments and interpreting platelet reactivity measures.

In the 21st century, cancer remains a serious threat to people's health and has become a prominent public health problem. NFKBIA is involved in the pathological process of many diseases including cancer, but its specific role in pan-cancer has not yet been fully elucidated. This study aims to deepen the understanding of cancer pathology by analyzing the potential functions of NFKBIA in pan-cancer. We used TCGA data to analyze differences of expression of NFKBIA in pan-cancer. We explored the prognostic value, clinical relevance, immune relevance, potential biological function, and diagnosis and treatment value of NFKBIA in pan-cancer through bioinformatics analysis. This study found that in pan-cancer, NFKBIA exhibits differences in expression, which correlate with the prognosis, diagnosis, treatment value and clinical and immune parameters. We have identified that Aspirin, Astaxanthin and Bardoxolone methyl are expected to play a potential therapeutic role in pan-cancer. The results of this study will help to improve our understanding of the role and potential mechanism of NFKBIA in cancer pathology, which may provide guidance for cancer-related research and clinical diagnosis and treatment.

Review
BACKGROUND
Acute coronary syndrome due to coronary artery embolism in the setting of ascending aortic thrombus is an uncommon condition, even rarer when there is no aortic pathology such as aneurysm, severe atherosclerosis, aortic dissection, or thrombophilia (whether inherited or acquired).
CASE PRESENTATION
We report a case of a 58-year-old male presented with acute chest pain, electrocardiogram showing non-ST-elevation acute coronary syndrome. The computed tomography angiography of coronary artery revealed a mural thrombus in the proximal part of ascending aorta, located above the left coronary artery ostium, without any aortic pathologies. With the exception of hypertension and cigarette smoking, no other risk factors were identified in this patient that may increase the risk of thrombosis. Given the life-threatening risk of interventional therapy and surgery, the patient determinedly opted for anticoagulant and dual antiplatelet therapy. Then he experienced the reoccurrence of chest pain after 6-day treatment, progressed to anterior and inferior ST-segment elevation myocardial infarction. Coronary artery embolism originating from the ascending aortic thrombus was suspected. Considering the hemodynamic instability of the patient, the medical treatment was continued and bridged to warfarin and aspirin after discharge. Follow-up computed tomography angiography at 6 months showed no obstruction in coronary artery and complete resolution of the thrombus. No thromboembolic events occurred henceforward.
CONCLUSIONS
Acute coronary syndrome could be a manifestation of secondary coronary embolism due to ascending aortic thrombus. Currently, there is no standardized guideline for the treatment of aortic mural thrombus, individualized treatment is recommended. When surgical therapy is not applicable for the patient, anticoagulation and dual antiplatelet treatment are alternative treatments that may successfully lead to the resolution of the aortic thrombus.
