REVIEW
Oscar J Cordero, Rubén Varela-Calviño
Many evidences support that species from the Human Oral Microbiome Database such as Fusobacterium nucleatum or Bacteroides, linked previously to periodontitis and appendicitis, play a role in colorectal cancer (CRC), including metastasis. These typically oral species are invasive anaerobes that form biofilms in their virulent state. Aspirin (a NSAID) has been recently included into routine CRC prevention rationale. NSAIDs can prevent the growth of neoplastic lesions by inhibiting COX enzymes and another set of recently identified COX-independent targets, which include the WNT, AMPK and MTOR signaling pathways, the crosstalk between nucleoli and NF-κB transcriptional activity in apoptosis, and the biochemistry of platelets...

The concomitant use of low-dose aspirin for cardioprotection and non-steroidal anti-inflammatory agents for pain relief is prevalent, particularly in the elderly for whom cardiovascular disease and pain are common co-morbidities. Non-selective non-steroidal anti-inflammatory drugs (NSAIDs) are known to interfere with the antiplatelet effect of aspirin through competitive binding with COX-1. While the clinical significance of this interference is still unclear, this review sought to assess the body of literature which has evaluated the potential attenuation of the anti-platelet effect of aspirin when dosed concomitantly with an NSAID...

Background Clopidogrel was thought to be superior to aspirin for secondary prevention of vascular diseases in clinical trials. In this study we assessed the safety and efficacy of clopidogrel versus aspirin in real-world practice by using the Taiwan Stroke Registry. Methods and Results Patients with ischemic stroke (2006-2016) on aspirin or clopidogrel for secondary stroke prevention were identified in the Taiwan Stroke Registry. Stroke recurrence and mortality rates in patients receiving aspirin (N=34 679) were compared with those receiving clopidogrel (N=7611) during a 12-month follow-up period...

Importance: Ovarian cancer is a highly fatal malignant neoplasm with few modifiable risk factors. Case-control studies have reported a modest reduced risk of ovarian cancer among women who frequently use aspirin or regularly use low-dose aspirin. Objective: To evaluate whether regular aspirin or nonaspirin nonsteroidal anti-inflammatory drug (NSAID) use and patterns of use are associated with lower ovarian cancer risk. Design, Setting, and Participants: This cohort study analyzed NSAID use and ovarian cancer diagnosis data from 2 prospective cohorts, 93 664 women in the Nurses' Health Study (NHS), who were followed up from 1980 to 2014, and 111 834 in the Nurses' Health Study II (NHSII), who were followed up from 1989 to 2015...

Non-steroidal anti-inflammatories (NSAIDs) are among the most commonly used drugs in clinical practice. They block cyclooxygenases (COX) enzymes, but the degree of inhibition of COX-1 and COX-2 varies between them. In general, NSAIDs are classified in selective COX-2 or coxibs and non-selective or traditional NSAIDs. Both the analgesic and antiinflammatory effects, as well as the cardiovascular adverse effects, depend on the COX-2 inhibition. This paper reviews the available evidence of the increased risk of thrombotic events for both coxibs and traditional NSAID...

Platelet activation plays a key role in atherogenesis and atherothrombosis. Biochemical evidence of increased platelet activation in vivo can be reliably obtained through non-invasive measurement of thromboxane metabolite (TXM) excretion. Persistent biosynthesis of TXA2 has been associated with several ageing-related diseases, including acute and chronic cardio-cerebrovascular diseases and cardiovascular risk factors, such as cigarette smoking, type 1 and type 2 diabetes mellitus, obesity, hypercholesterolemia, hyperhomocysteinemia, hypertension, chronic kidney disease, chronic inflammatory diseases...

OBJECTIVE/BACKGROUND: The development of an abdominal aortic aneurysm (AAA) involves extensive extracellular matrix remodelling, leading to aortic wall weakening. This process is mediated by proteases, including cysteinyl cathepsins. Cystatins are their endogenous inhibitors. This study tested whether plasma cystatin B levels in patients with AAA differed from those of healthy controls. METHODS: Plasma samples from patients with AAA and age matched controls were selected from the Viborg Vascular (VIVA) screening trial for AAA...

Observational studies of aspirin use and breast cancer risk have provided inconsistent results. The occurrence of contralateral breast cancer (CBC) among breast cancer survivors may serve as a useful high-risk model to identify preventive drug effects. Using this model, we examined the association between post-diagnosis use of low-dose aspirin and risk of CBC. We identified all women recorded with a first primary breast cancer in the Danish Breast Cancer Cooperative Group Database between 1996 and 2012. Information on drug use, tumor and patient characteristics, treatment, and CBC was obtained from nationwide registries...

Diabetes is a major risk factor for cardiovascular diseases. Although aspirin is considered a cornerstone of the prevention and treatment of atherothrombotic-related ischemic events, this antiplatelet drug appears to be less effective in patients with poorly controlled diabetes. It has been suggested that the glycation of platelet proteins plays a pivotal role in poor responsiveness to aspirin. However, a direct effect on the critical residue (serine 529, or Ser 529) of the catalytic pocket of cyclooxygenase 1 (COX-1) has never been demonstrated...

INTRODUCTION: According to the present knowledge, the effect of non-steroidal anti-inflammatory drugs (NSAIDs) depends on the inhibitory ratio of cyclooxigenase (COX)-1 to COX-2 in the plasma membranes. In addition to cardiovascular and gastrointestinal side effects, there are adverse symptoms which can be divided into cross-intolerance (non-immune mediated) and single or multiple hypersensitive (immune mediated) reactions. Due to clinical phenotypes and to in vivo aspirin reactivity, adverse effects could be further classified...

Cancer stem-like cells (CSCs) have been proposed as a key driving force of tumor growth and relapse in colorectal cancer (CRC), and therefore, they are promising targets for cancer therapy. Epidemiological evidence has suggested that the daily use of aspirin reduces overall mortality of CRC and the risk of distant metastasis. We investigated the effect and mechanism of aspirin on CSCs in CRC. Methods: The ratio of CSCs was analyzed after aspirin treatment both in a cell model and patient samples. Chemically modified aspirin and immunoprecipitation were adopted to detect the target proteins of aspirin...
