Aspirin: The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. (From Martindale, The Extra Pharmacopoeia, 30th ed, p5)Platelet Aggregation Inhibitors: Drugs or agents which antagonize or impair any mechanism leading to blood platelet aggregation, whether during the phases of activation and shape change or following the dense-granule release reaction and stimulation of the prostaglandin-thromboxane system.Anti-Inflammatory Agents, Non-Steroidal: Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions.They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.Ticlopidine: An effective inhibitor of platelet aggregation commonly used in the placement of STENTS in CORONARY ARTERIES.Thromboxane B2: A stable, physiologically active compound formed in vivo from the prostaglandin endoperoxides. It is important in the platelet-release reaction (release of ADP and serotonin).Cyclooxygenase Inhibitors: Compounds or agents that combine with cyclooxygenase (PROSTAGLANDIN-ENDOPEROXIDE SYNTHASES) and thereby prevent its substrate-enzyme combination with arachidonic acid and the formation of eicosanoids, prostaglandins, and thromboxanes.Platelet Aggregation: The attachment of PLATELETS to one another. This clumping together can be induced by a number of agents (e.g., THROMBIN; COLLAGEN) and is part of the mechanism leading to the formation of a THROMBUS.Salicylates: The salts or esters of salicylic acids, or salicylate esters of an organic acid. Some of these have analgesic, antipyretic, and anti-inflammatory activities by inhibiting prostaglandin synthesis.Platelet Function Tests: Laboratory examination used to monitor and evaluate platelet function in a patient's blood.Drug Therapy, Combination: Therapy with two or more separate preparations given for a combined effect.Blood Platelets: Non-nucleated disk-shaped cells formed in the megakaryocyte and found in the blood of all mammals. They are mainly involved in blood coagulation.Sodium Salicylate: A non-steroidal anti-inflammatory agent that is less effective than equal doses of ASPIRIN in relieving pain and reducing fever. However, individuals who are hypersensitive to ASPIRIN may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as ASPIRIN, but there is less occult gastrointestinal bleeding. (From AMA Drug Evaluations Annual, 1992, p120)Fibrinolytic Agents: Fibrinolysin or agents that convert plasminogen to FIBRINOLYSIN.Hemorrhage: Bleeding or escape of blood from a vessel.Asthma, Aspirin-Induced: Asthmatic adverse reaction (e.g., BRONCHOCONSTRICTION) to conventional NSAIDS including aspirin use.Anticoagulants: Agents that prevent clotting.Warfarin: An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.Tablets, Enteric-Coated: Tablets coated with material that delays release of the medication until after they leave the stomach. (Dorland, 28th ed)Cyclooxygenase 1: A constitutively-expressed subtype of prostaglandin-endoperoxide synthase. It plays an important role in many cellular processes.Bleeding Time: Duration of blood flow after skin puncture. This test is used as a measure of capillary and platelet function.Gastrointestinal Hemorrhage: Bleeding in any segment of the GASTROINTESTINAL TRACT from ESOPHAGUS to RECTUM.Prostaglandin-Endoperoxide Synthases: Enzyme complexes that catalyze the formation of PROSTAGLANDINS from the appropriate unsaturated FATTY ACIDS, molecular OXYGEN, and a reduced acceptor.Platelet Activation: A series of progressive, overlapping events, triggered by exposure of the PLATELETS to subendothelial tissue. These events include shape change, adhesiveness, aggregation, and release reactions. When carried through to completion, these events lead to the formation of a stable hemostatic plug.Thromboxanes: Physiologically active compounds found in many organs of the body. They are formed in vivo from the prostaglandin endoperoxides and cause platelet aggregation, contraction of arteries, and other biological effects. Thromboxanes are important mediators of the actions of polyunsaturated fatty acids transformed by cyclooxygenase.Ibuprofen: A nonsteroidal anti-inflammatory agent with analgesic properties used in the therapy of rheumatism and arthritis.Thromboxane A2: An unstable intermediate between the prostaglandin endoperoxides and thromboxane B2. The compound has a bicyclic oxaneoxetane structure. It is a potent inducer of platelet aggregation and causes vasoconstriction. It is the principal component of rabbit aorta contracting substance (RCS).Dose-Response Relationship, Drug: The relationship between the dose of an administered drug and the response of the organism to the drug.Thrombosis: Formation and development of a thrombus or blood clot in the blood vessel.Cyclooxygenase 2 Inhibitors: A subclass of cyclooxygenase inhibitors with specificity for CYCLOOXYGENASE-2.Double-Blind Method: A method of studying a drug or procedure in which both the subjects and investigators are kept unaware of who is actually getting which specific treatment.Dipyridamole: A phosphodiesterase inhibitor that blocks uptake and metabolism of adenosine by erythrocytes and vascular endothelial cells. Dipyridamole also potentiates the antiaggregating action of prostacyclin. (From AMA Drug Evaluations Annual, 1994, p752)Lipoxins: Trihydroxy derivatives of eicosanoic acids. They are primarily derived from arachidonic acid, however eicosapentaenoic acid derivatives also exist. Many of them are naturally occurring mediators of immune regulation.Acetaminophen: Analgesic antipyretic derivative of acetanilide. It has weak anti-inflammatory properties and is used as a common analgesic, but may cause liver, blood cell, and kidney damage.Drug Resistance: Diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. It should be differentiated from DRUG TOLERANCE which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration.Indomethacin: A non-steroidal anti-inflammatory agent (NSAID) that inhibits the enzyme cyclooxygenase necessary for the formation of prostaglandins and other autacoids. It also inhibits the motility of polymorphonuclear leukocytes.Risk Factors: An aspect of personal behavior or lifestyle, environmental exposure, or inborn or inherited characteristic, which, on the basis of epidemiologic evidence, is known to be associated with a health-related condition considered important to prevent.Myocardial Infarction: NECROSIS of the MYOCARDIUM caused by an obstruction of the blood supply to the heart (CORONARY CIRCULATION).Sulfinpyrazone: A uricosuric drug that is used to reduce the serum urate levels in gout therapy. It lacks anti-inflammatory, analgesic, and diuretic properties.Gastric Mucosa: Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.Cyclooxygenase 2: An inducibly-expressed subtype of prostaglandin-endoperoxide synthase. It plays an important role in many cellular processes and INFLAMMATION. It is the target of COX2 INHIBITORS.Reye Syndrome: A form of encephalopathy with fatty infiltration of the LIVER, characterized by brain EDEMA and VOMITING that may rapidly progress to SEIZURES; COMA; and DEATH. It is caused by a generalized loss of mitochondrial function leading to disturbances in fatty acid and CARNITINE metabolism.Stroke: A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature. (From Adams et al., Principles of Neurology, 6th ed, pp777-810)Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.Stomach Ulcer: Ulceration of the GASTRIC MUCOSA due to contact with GASTRIC JUICE.

Effect of paracetamol (acetaminophen) on gastric ionic fluxes and potential difference in man. (1/4641)Paracetamol has replaced aspirin as the analgesic of choice in many situations. The major reason is the damaging effect of aspirin on gastric mucosa. Alterations in gastric ionic fluxes and potential difference provide measures of aspirin-induced structural damage. We studied the effect of large doses of paracetamol (acetaminophen 2-0 g) on gastric ionic fluxes in man. In addition, the effect of 2-0 g paracetamol on gastric potential difference was compared with that of 600 mg aspirin. In contrast with salicylates, paracetamol caused no significant alteration in movement of H+ and Na+ ions over control periods. Aspirin causes a significant fall in transmucosal potential difference (PD) across gastric mucosa of 15 mv, while paracetamol cuased no significant change. Paracetamol in a dose four times that recommended does not alter gastric ionic fluxes or potential difference. These studies support choice of paracetamol as analgesic over aspirin where damage to gastric mucosa may be critical. (+info)
Non-steroidal anti-inflammatory drug-induced apoptosis in gastric cancer cells is blocked by protein kinase C activation through inhibition of c-myc. (2/4641)Apoptosis plays a major role in gastrointestinal epithelial cell turnover, ulcerogenesis and tumorigenesis. We have examined apoptosis induction by non-steroidal anti-inflammatory drugs (NSAIDs) in human gastric (AGS) cancer cells and the role of protein kinase C (PKC) and apoptosis-related oncogenes. After treatment with aspirin or indomethacin, cell growth was quantified by MTT assay, and apoptosis was determined by acridine orange staining, DNA fragmentation and flow cytometry. The mRNA and protein of p53, p21waf1/cip1 and c-myc was detected by Northern and Western blotting respectively. The influence of PKC on indomethacin-induced apoptosis was determined by co-incubation of 12-O-tetradecanoylphorbol 13-acetate (TPA). The role of c-myc was determined using its antisense oligonucleotides. The results showed that both aspirin and indomethacin inhibited cell growth and induced apoptosis of AGS cells in a dose- and time-dependent manner, without altering the cell cycle. Indomethacin increased c-myc mRNA and protein, whereas p53 and p21wafl/cip1 were unchanged. Down-regulation of c-myc by its antisense oligonucleotides reduced apoptosis induction by indomethacin. TPA could inhibit indomethacin-induced apoptosis and accumulate cells in G2/M. Overexpression of c-myc was inhibited by TPA and p21waf1/cip1 mRNA increased. In conclusion, NSAIDs induce apoptosis in gastric cancer cells which may be mediated by up-regulation of c-myc proto-oncogene. PKC activation can abrogate the effects of NSAIDs by decreasing c-myc expression. (+info)
Influence of a new antiulcer agent, ammonium 7-oxobicyclo (2, 2, 1) hept-5-ene-3-carbamoyl-2-carboxylate (KF-392) on gastric lesions and gastric mucosal barrier in rats. (3/4641)Antiulcer effects of KF-392 were studied in several experimental gastric ulcer models in rats. It was found that KF-392 given orally at 1.0 to 5.0 mg/kg had a marked suppression on the developments of Shay ulcer as well as the aspirin-, stress-, and reserpine-induced gastric lesions. The influence of KF-392 on gastric mucosal barrier was also studied. A back diffusion of H+ into the gastric mucosa and a fall of transmucosal potential difference were induced with KF-392 given orally at the above mentioned doses. KF-392 given s.c. at 5.0 mg/kg showed no inhibition of Shay ulcer and no induction of back diffusion of H+ into the gastric mucosa. (+info)
Anti-ulcer effects of 4'-(2-carboxyetyl) phenyl trans-4-aminomethyl cyclohexanecarboxylate hydrochloride (cetraxate) on various experimental gastric ulcers in rats. (4/4641)Anti-ulcer effects of cetraxate, a new compound possessing anti-plasmin, anti-casein and anti-trypsin actions were investigated by using experimental gastric ulcer models in rats. Cetraxate, 300 mg/kg p.o. showed significant inhibitory effects of 65.3%, 70.0%, 30.2%, and 67.1% against aucte types of ulcers producing by aspirin, phenylbutazone, indomethacin, and pyloric ligature (Shay's ulcer), respectively. These effects were greater than those obtained by gefarnate and aluminum sucrose sulfate may be mainly attributed to the protecting action of this drug on gastric mucosa. Ctraxate further revealed remarkable inhibitory effects on chronic types of ulcers produced by acetic acid, clamping, and clamping-cortisone. In acetic acid ulcer in particular, cetraxate was found to have a dose-dependent inhibitory effect at doses over 50 mg/kg. Of test drugs including L-glutamine and methylmethionine sulfonium chloride, cetraxate showed the most remarkable inhibitory effect on beta-glucuronidase activity in ulcer tissue of these three types of ulcers. These findings suggest that cetraxate may prevent the connective tissue in the ulcer location from decomposition due to lysosomal enzymes such as beta-glucuronidase, thereby accelerating the recovery from ulcer.

Inhibitory effects of copper-aspirin complex on platelet aggregation. (5/4641)AIM: To study the inhibitory effects of copper-aspirin complex (CuAsp) on platelet aggregation. METHODS: With adenosine diphosphate the effects of CuAsp on platelet aggregation in vitro or in vivo were investigated. Radioimmunoassay and fluorophotometry were used to measure thromboxane B2 (TXB2) generation from platelets, the levels of TXB2 and of 6-keto-PGF1 alpha in plasma and the platelet serotonin release reaction. RESULTS: In vitro, CuAsp inhibited arachidonic acid (AA)-induced aggregation (IC50 = 17 mumol.L-1, 95% confidence limits: 9-33 mumol.L-1), the release of 5-HT (IC50 = 19 mumol.L-1, 95% confidence limits: 10-30 mumol.L-1), and TXB2 generation from platelets (P < 0.05). CuAsp 10 mg.kg-1 i.g. selectively inhibited AA-induced aggregation, and increased the 6-keto-PGF1 alpha concentration in plasma while decreased that of TXB2. CONCLUSION: CuAsp, in vitro or in vivo, shows more potent inhibitory effects on AA-induced aggregation than aspirin (Asp), related to the inhibition of platelet cyclooxygenase and the release of active substances from platelets.

Effects of nicorandil on experimentally induced gastric ulcers in rats: a possible role of K(ATP) channels. (6/4641)The anti-ulcer effects of nicorandil [N-(2-hydroxyethyl)nicotinamide nitrate ester] were examined on water-immersion plus restraint stress-induced and aspirin-induced gastric ulcers in rats, compared with those of cimetidine. Nicorandil (3 and 10 mg/kg) given orally to rats dose-dependently inhibited the development of acid-related damage (water-immersion- and aspirin-induced gastric lesions) in the models. Cimetidine (50 mg/kg, p.o.) also had anti-ulcer effects in the same models. However, in the presence of glibenclamide (20 mg/kg, i.v.), an antagonist of K(ATP) channels, nicorandil did not inhibit the formation of gastric lesions. Nicorandil (10 mg/kg) given intraduodenally (i.d.), like cimetidine (50 mg/kg), significantly reduced the volume of the gastric content, total acidity and total acid output in the pylorus ligation model. Glibenclamide reversed the changes caused by i.d. nicorandil. I.v. infusion of nicorandil (20 microg/kg per min) significantly increased gastric mucosal blood flow, without affecting blood pressure and heart rate, but the increase in the blood flow was not observed after i.v. treatment with glibenclamide (20 mg/kg). These results indicate that nicorandil administered orally to rats produces the anti-ulcer effect by reducing the aggressive factors and by enhancing the defensive process in the mucosa through its K(ATP)-channel-opening property.

Risk of primary intracerebral haemorrhage associated with aspirin and non-steroidal anti-inflammatory drugs: case-control study. (7/4641)OBJECTIVE: To examine the association between use of aspirin or other non-steroidal anti-inflammatory drugs and intracerebral haemorrhage. DESIGN: Case-control study. SETTING: 13 major city hospitals in the Melbourne and metropolitan area. SUBJECTS: 331 consecutive cases of stroke verified by computed tomography or postmortem examination, and 331 age (+/- 5 years) and sex matched controls who were community based neighbours. INTERVENTIONS: Questionnaire administered to all subjects either directly or by proxy with the next of kin. Drug use was validated by reviewing prescribing records held by the participants' doctors. MAIN OUTCOME MEASURES: Previous use of aspirin or other non-steroidal anti-inflammatory drugs. RESULTS: Univariate analysis showed no increased risk of intracerebral haemorrhage with low dose aspirin use in the preceding 2 weeks. Using multiple logistic regression to control for possible confounding factors, the odds ratio associated with the use of aspirin was 1.00 (95% confidence interval 0.60 to 1. 66, P=0.998) and the odds ratio associated with the use of other non-steroidal anti-inflammatory drugs was 0.85 (0.45 to 1.61, P=0. 611) compared with respective non-users in the preceding fortnight. Moderate to high doses of aspirin (>1225 mg/week spread over at least three doses) yielded an odds ratio of 3.05 (1.02 to 9.14, P=0. 047). There was no evidence of an increased risk among subgroups defined by age, sex, blood pressure status, alcohol intake, smoking, and the presence or absence of previous cardiovascular disease. CONCLUSIONS: No increase in risk of intracerebral haemorrhage was found among aspirin users overall or among those who took low doses of the drug or other non-steroidal anti-inflammatory drugs. These data provide evidence that doses of aspirin usually used for prophylaxis against vascular disease produce no substantial increase in risk of intracerebral haemorrhage. (+info)
Prevention of persistent cerebral smooth muscle contraction in response to whole blood. (8/4641)Using an in vitro system designed to measure arterial constriction, we have demonstrated the importance of platelet function in maintaining cerebral smooth muscle contraction after whole blood injection. We tested two agents, acetyl salicylic acid (ASA) and phthalazinol, both known to interfere with platelet function. In control tests normal rabbit and monkey blood produced a reliable and persistent arterial constriction. In experimental tests blood drawn from animals premedicated with ASA and phthalazinol failed to produce a persistent contraction. These results support the hypothesis that chemicals released during platelet aggregation may be important in persistent vasospasm. (+info)

A new study found that regular aspirin use is significantly associated with an increased incidence of neovascular AMD, a leading cause of blindness in older people.. Researchers at the Center for Vision Research from the Westmead Millennium Institute for Medical Research (WMI), a close affiliate of the University of Sydney, have found that regular aspirin consumption is associated with an increased risk of neovascular age-related macular degeneration (AMD) - a leading cause of blindness in older people.. The research shows that the risk appears to be independent of a history of smoking, which is also a known preventable risk factor for AMD.. Aspirin is one of the most widely used medications in the world with more than 100 billion tablets consumed each year. Aspirin is commonly used in the prevention of cardiovascular disease, such as myocardial infarction (heart attack) and ischemic stroke.. While a five-year European study published last year suggested that regular aspirin use (defined as once ...

Discontinuation of low dose aspirin and risk of myocardial infarction: case-control study in UK primary care | The BMJ
A major strength of this study is that use of The Health Improvement Network enabled analysis of an extensive sample that was representative of the UK primary care population and had age and sex distributions similar to those in the national population. Also, the network includes all patients in participating practices who have been diagnosed as having a primary cardiovascular event and prescribed low dose aspirin to prevent a secondary event in primary care, supporting the broad external validity of these findings. Moreover, we observed the increased risk of non-fatal myocardial infarction in patients who were truly non-adherent but not in those who were found to be taking over the counter aspirin, which reinforces the internal validity of this study.. A potential limitation of the study is that use of aspirin might have been misclassified in some cases. For example, the recording of a prescription for low dose aspirin in The Health Improvement Network does not necessarily mean that the patient ...

3BL Media) Atlanta, GA - August 31, 2012 - A large new observational study finds more evidence of an association between daily aspirin use and modestly lower cancer mortality, but suggests any reduction may be smaller than that observed in a recent analysis. The study, appearing early online in the Journal of the National Cancer Institute (JNCI), provides additional support for a potential benefit of daily aspirin use for cancer mortality, but the authors say important questions remain about the size of the potential benefit.. A recent analysis pooling results from existing randomized trials of daily aspirin for prevention of vascular events found an estimated 37% reduction in cancer mortality among those using aspirin for five years or more. But uncertainty remains about how much daily aspirin use may lower cancer mortality, as the size of this pooled analysis was limited and two very large randomized trials of aspirin taken every other day found no effect on overall cancer mortality.. For the ...

Estrogen receptor negative (ER(−)) breast cancer is aggressive, responds poorly to current treatments and has a poor prognosis. The NF-κB signaling pathway is implicated in ER(−) tumorigenesis. Aspirin (ASA) is chemopreventive against ER(+) but not for ER(−) breast cancers. Nitric oxide-releasing aspirin (NO-ASA) is a safer ASA where ASA is linked to an NO-releasing moiety through a spacer. In vitro, we investigated anti-proliferation effects of NO-ASA (para- and meta-isomers) against ER(−) breast cancer cells MDA-MB-231 and SK-BR-23, effects on NF-κB signaling, and reactive oxygen species by standard techniques. In vivo, effects of NO-ASA were evaluated in a mouse xenograft model using MDA-MB-231 cells. p-NO-ASA inhibited the growth of MDA-MB-231 and SK-BR-3 cells at 24 h, the respective IC50s were 13 ± 2 and 17 ± 2 μM; ASA had an IC50 of |3000 μM in both cell lines. The IC50s for m-NO-ASA in MDA-MB-231 and SK-BR-3 were 173 ± 15 and 185 ± 12 μM, respectively, therefore, implying p-NO

The U.S. Preventive Services Task Force recently recommended daily aspirin therapy if youre age 50 to 59 years, youre not at increased bleeding risk, and you have an increased risk of heart attack or stroke of 10 percent or greater over the next 10 years. If youre age 60 to 69, you arent at increased bleeding risk, and you have a high risk of heart attack or stroke of 10 percent or greater over the next 10 years, talk to your doctor about daily aspirin therapy. More research is needed to determine the benefits and risks of daily aspirin use in adults younger than age 50 and older than age 70 before a recommendation can be made for or against aspirin use to prevent cardiovascular disease and colorectal cancer for these age groups.. Although aspirin has been recommended in the past for certain groups of people without a history of heart attack, theres some disagreement among experts about whether the benefits of aspirin outweigh its potential risks. The Food and Drug Administration doesnt ...
Quitting daily aspirin therapy may increase second heart attack, stroke risk - A Woman's Health - Women Magazine
Low-dose aspirin therapy is a simple and inexpensive treatment," said Johan Sundstrom, M.D., Ph.D., lead author and professor of epidemiology at Uppsala University in Sweden. "As long as theres no bleeding or any major surgery scheduled, our research shows the significant public health benefits that can be gained when patients stay on aspirin therapy.". Studies have suggested patients experience a "rebound effect" after stopping aspirin treatment, this is possibly due to increased clotting levels from the loss of aspirins blood-thinning effects. Because of the large number of patients on aspirin and the high number who stop treatment, the importance of a rebound effect may be significant, Sundstrom said.. "We hope our research may help physicians, healthcare providers and patients make informed decisions on whether or not to stop aspirin use," Sundstrom said.. The American Heart Association recommends that people at high risk of heart attack should take a daily low-dose of aspirin (if told to ...

Among study participants who reported whether or not they used aspirin regularly: 18 percent used aspirin, 24 percent used non-aspirin NSAIDs, and 16 percent used acetaminophen. The researchers determined that participants who reported daily aspirin use had a 20 percent lower risk of ovarian cancer than those who used aspirin less than once per week. For non-aspirin NSAIDs, which include a wide variety of drugs, the picture was less clear: the scientists observed a 10 percent lower ovarian cancer risk among women who used NSAIDs at least once per week compared with those who used NSAIDs less frequently. However, this finding did not fall in a range that was significant statistically. In contrast to the findings for aspirin and NSAIDs, use of acetaminophen, which is not an anti-inflammatory agent, was not associated with reduced ovarian cancer risk ...

Daily, low-dose aspirin (75-100 mg) was associated with reduced risk for cardiovascular events among those weighting less than 70 kg (odds ratio, 0.77), but there was no significant effect for heavier patients - roughly 80% of men in the study and nearly half of women weighted 70 kg or more. In the heavier group, low-dose aspirin may be even less effective in smokers and in those who take enteric-coated aspirin ...
Numerous studies document the multiple health benefits of daily low dose aspirin. Aspirin helps to maintain normal platelet aggregation in blood vessels and the production of prostaglandin E2 and possibly C-reactive protein.
Too much use of Aspirin can cause severe affect on your health and can be the reason of Cancer and Heart Attack. In- Details:. According the health research laboratories daily aspirin therapy is reason behind the increasing number of cases for heart attack and cancer diseases.. NHS Researcher found the risk more than its benefits; they told that It can bleed your brain and stomach.. Doctors advice you aspirin therapy after first stroke or first heart attack, which can make your blood in flow steadily in your veins, this therapy is not good for all patients. Mostly more 50 years old patients are recommended for low dose Aspirin.. Daily dose recommended to those patient who have heart disease because the aspirin remove the blood clots by diluting it into the smooth blood .. If you dont have any heart diseases then and you are regularly taking this dose can affective for your health and you may be get strokes or heart attack. These drugs are healthy to remove the chance of building blood clots but ...
Experts go head to head in this weeks BMJ over whether everyone over 50 should take a daily aspirin to reduce their risk of heart attacks and strokes. Peter Elwood and colleagues at Cardiff University believe that the evidence now supports more widespread use of aspirin, and there needs to be a strategy to inform the public and enable older people to make their own decision. As a general rule, daily aspirin is given only to people whose five year risk of a vascular event, such as a heart attack or stroke, is 3% or more. The authors show that, by age 50, 80% of men and 50% of women reach this level of risk and they suggest that 90-95% of the population could take low dose aspirin without problems. Evidence is also growing that regular aspirin may reduce cancer and dementia. "The possibility that a simple, daily, inexpensive low dose pill would achieve a reduction in vascular events, and might achieve reductions in cancer and dementia without the need for screening, deserves serious ...

Objectives To investigate the benefits and risks associated with aspirin treatment in patients with type 2 diabetes and no previous cardiovascular disease (CVD) in clinical practice. Design Population-based cohort study between 2005 and 2009, mean follow-up 3.9years. Setting Hospital outpatient clinics and primary care in Sweden. Participants Men and women with type 2 diabetes, free from CVD, including atrial fibrillation and congestive heart failure, at baseline, registered in the Swedish National Diabetes Register, with continuous low-dose aspirin treatment (n=4608) or no aspirin treatment (n=14038). Main outcome measures Risks of CVD, coronary heart disease (CHD), stroke, mortality and bleedings, associated with aspirin compared with no aspirin, were analysed in all patients and in subgroups by gender and estimated cardiovascular risk. Propensity scores were used to adjust for several baseline risk factors and characteristics at Cox regression, and the effect of unknown covariates was ...

1994 - Aspirin did not prevent pre-eclampsia or intrauterine growth retardation | 1994 Sep-Oct : Volume 121, Number 2, Page 47 ...
In recent years, the prevention of pre-eclampsia has focused on low-dose aspirin therapy. In 1991, a meta-analysis of 6 trials of women taking low-dose aspirin who were judged to be at high risk for pregnancy-induced hypertension, a subset of which is pre-eclampsia, suggested a 65% reduction in this incidence and a 44% reduction in the incidence of low-birth-weight infants (1). A new meta-analysis, which includes the CLASP report plus 16 published trials of women taking low-dose aspirin who had pre-eclampsia or who were at risk for pre-eclampsia, indicated a 25% reduction in the incidence. In absolute terms, this means that to prevent pre-eclampsia in 1 woman, 56 must be treated. Important inconsistencies, however, exist among these trials. Why was the benefit of aspirin less apparent in CLASP? In some of the previous trials of women at high risk, the incidence of pre-eclampsia was 17% to 52% in the placebo group (1). This far exceeds the risk of 6% to 8% noted in CLASP, a study which more ...
A brand new study held in Spain has shown that healthy people who are taking a daily aspirin dose to prevent heart attacks may actually be useless. Daily supplementation also led to high rates of internal bleeding - a serious condition that, if left unattended, can lead to major health risks.. Scottish scientists told a meeting of heart specialists in Spain that a their large scale study of more than 3000 men showed that daily aspirin use did not significantly reduce the risk of heart attack or stroke. The scientists also found that it almost doubled the risk of being admitted to hospital because of internal bleeding.. Professor Gerry Fowkes, of Edinburghs Wolfson Unit for Prevention of Peripheral Vascular Disease, said the research showed the blood-thinning drug should not be prescribed to the general population.. "Aspirin probably leads to a minor reduction in future events, but the problem is that has to be weighed against an increase in bleeding," he said. "Some of that bleeding can be ...

MONDAY, May 1, 2017 (HealthDay News) -- Score yet another point for low-dose aspirin: Regularly taking "baby" aspirin appears to protect women from the most common type of breast cancer, new research suggests.. Use of low-dose aspirin at least three times a week was linked to a 20 percent risk reduction for cancers known as hormone-receptor positive, HER2 negative -- the most common breast cancer subtype, said study senior author Leslie Bernstein.. Thats a "moderate" reduction in risk, said Bernstein, a professor at the City of Hope Cancer Center in Duarte, Calif. Its "maybe not as good as exercise," she said, but she added that more people might adhere to an aspirin regimen than an exercise routine.. However, the study doesnt establish a direct cause-and-effect relationship, and Bernstein said its too early to recommend taking daily aspirin for breast-cancer risk reduction.. Many adults already take low-dose aspirin (81 milligrams) daily to lower their risk of heart attack. This study -- ...

Though research into using aspirin to prevent cancer and heart disease has been ongoing for many years, a recently published study found that daily aspirin use may help to reduce the overall chances of mortality in colon cancer patients. The ten-year study, conducted in Holland, showed that colon cancer patients could reduce their chances of dying by as much as 33 percent by taking 80mg of aspirin every day for at least 9 months.. Life-saving Potential. Though aspirin should not be used in lieu of other treatments for colon cancer, this is the first time the over-the-counter medicine has come into discussion as a potentially useful drug for complementing other cancer treatment procedures. Aspirin is by no means a treatment of cancer in and of itself.. A Few Caveats. More research is needed before experts can definitively recommend daily aspirin use to all older patients of colon cancer. The studys results do not conclusively prove that aspirin use has any direct impact on the reduction of ...
Prevention of Recurrent Ulcer Bleeding in High-risk Users of Low-dose Aspirin - Full Text View - ClinicalTrials.gov
Low-dose aspirin is increasingly used for the prophylaxis against coronary heart disease and stroke. However, it is also an important cause of peptic ulcer bleeding worldwide. In England and Wales, low-dose aspirin is estimated to account for about 10% of ulcer bleeding in people aged 60 and over [Weil 1995]. The problem of aspirin-related ulcer disease is expanding with the increasing use of aspirin for cardiovascular prophylaxis.. No dose of aspirin is entirely free of risk. Using a daily dose of aspirin as low as 75 mg, the risk of ulcer bleeding doubles that of non-users [Weil 1995]. Previous ulcer disease and concurrent major medical illnesses are important risk factors for ulcer bleeding with low-dose aspirin. Among aspirin users, those with previous ulcer disease have a 5-fold increased risk of ulcer bleeding [Lanas 2000]. Recently the investigators have shown that among aspirin users who are infected with H. pylori, the eradication of H. pylori is comparable to omeprazole in preventing ...
Sonia Hernández-Díaz and Luis García Rodríguez analysed two anonymous databases of patient information, the General Practice Research Database in the UK and the Base de Datos para la Investigación Farmacoepidemiológica en Atención Primaria in Spain, to characterise patients taking low-dose aspirin as a preventive measure against heart attack, in terms of major gastrointestinal risk factors. Risk factors for upper gastrointestinal tract complications include advanced age, male sex, prior ulcer history and use of other non-steroidal anti-inflammatory drugs (NSAIDs). The researchers then estimated the excess gastrointestinal risk caused by aspirin use in patients with and without these risk factors. Hernández-Díaz and García Rodríguez find that 88% of aspirin users are over 60 and that 52-54% of them are male. From 3.8% to 5.9% of them have a history of gastrointestinal ulcer. Across all risk groups, aspirin use is responsible for an extra 5-6 cases of upper gastrointestinal tract ...
A prospective, blinded determination of the natural history of aspirin resistance among stable patients with cardiovascular...
In this blinded, prospective study, we demonstrated aspirin resistance as documented by optical platelet aggregation testing to be negatively associated with long-term outcomes in a population of stable cardiovascular patients. Previous studies have demonstrated aspirin resistance by both clinical evidence of unresponsiveness to aspirin (8)and ex vivo platelet function testing (5,9-13). To date only three studies have evaluated the clinical consequence of aspirin resistance in select populations (14-16). Grotemeyer et al. (14)evaluated 180 acute stroke patients for evidence of aspirins effect on platelet reactivity. Patients with elevated platelet reactivity despite aspirin were more likely to experience vascular death, MI, or CVA. Mueller et al. (15)reported an association between failed inhibition of platelet reactivity by aspirin and risk of reocclusion after peripheral vascular angioplasty in patients with claudication. Most recently, Eikelboom et al. (16)reported an increased risk for MI, ...
Effects of regular aspirin on long-term cancer incidence and metastasis: A systematic comparison of evidence from observational...
Background: Long-term follow-up of randomised trials of aspirin in prevention of vascular events showed that daily aspirin reduced the incidence of colorectal cancer and several other cancers and reduced metastasis. However, statistical power was inadequate to establish effects on less common cancers and on cancers in women. Observational studies could provide this information if results can be shown to be reliable. We therefore compared effects of aspirin on risk and outcome of cancer in observational studies versus randomised trials. Methods: For this systematic review, we searched for case-control and cohort studies published from 1950 to 2011 that reported associations between aspirin use and risk or outcome of cancer. Associations were pooled across studies by meta-analysis and stratified by duration, dose, and frequency of aspirin use and by stage of cancer. We compared associations from observational studies with the effect of aspirin on 20-year risk of cancer death and on metastasis in the

Cardiologist Ezra Amsterdam specializes in helping patients manage acute ischemic syndromes, chest pain, post-myocardial infarction risk and coronary artery disease. He is frequently called upon to help establish and update national standards for treating and preventing cardiac disease.. The greater the risk for a heart attack or stroke, the more likely the benefits of aspirin will outweigh the risks. Risk is highest in those who have had a heart attack, ischemic stroke (caused by a clot) or TIA (so-called "mini" or "warning" stroke), and doctors usually advise daily aspirin for these individuals to help prevent a second event. Aspirin is also standard therapy in patients who have had a stent placed in a coronary artery.. Those who cannot tolerate aspirins side effects may be asked to try enteric-coated aspirin instead, add a proton pump inhibitor (PPI) to reduce GI symptoms or substitute clopidogrel (Plavix), which also reduces blood clots. Some who have not had a stroke or heart attack may ...
2006 - Clopidogrel plus aspirin did not differ from aspirin alone for reducing MI, stroke, and CV death in high-risk...
Aspirin, which blocks the platelet cyclooxygenase pathway, is effective for preventing vascular events (1). Recent short-term studies combining aspirin with clopidogrel, another antiplatelet drug that blocks the adenosine diphosphate P2Y12 receptor, have shown significant benefit in patients with acute coronary syndromes and those undergoing percutaneous revascularization (2). The CHARISMA trial by Bhatt and colleagues was designed to determine if long-term therapy with aspirin plus clopidogrel was better than aspirin alone in patients at high risk for atherothrombosis. Overall, there was no benefit in using dual therapy over aspirin alone for the primary outcome and only a small benefit for the secondary outcome. However, it is logical that if dual therapy is effective for short-term therapy in acute coronary syndromes, there may be some patients for whom long-term therapy might also be beneficial. To address this possibility, the authors did a prespecified subgroup analysis, including patients ...
New research has shown that taking a daily aspirin - long a standard practice - wont necessarily keep a heart attack away for generally healthy adults who have low to moderate risk for a heart attack or stroke.. And in older adults with no cardiovascular risk factors, aspirin could actually cause more harm than good.. "Were shying away from giving everyone, including senior adults, a daily low-dose aspirin, said Carlos R. Zamora, MD, a cardiologist with Baptist Heart Specialists. "We are now taking a more individualized approach in deciding who really needs it.". Despite being a common practice for decades, prescribing a daily dose of so-called "baby aspirin" is no longer recommended by the American Heart Association or the American College of Cardiology. The two organizations recently released new low-dose aspirin guidelines after clinical trials showed the benefits dont always outweigh the risks, which include an increase in internal bleeding, particularly in the gastrointestinal ...
Limit alcohol. Drinking 3 or more alcoholic drinks every day while taking daily aspirin increases your risk for liver damage and stomach bleeding. If your doctor recommends aspirin, limit or stop alcohol usage.. Talk to doctor before a surgery or procedure.

Low-Dose Acetylsalicylic Acid in Treating Patients With Stage I-III Non-Small Cell Lung Cancer - Full Text View -...
PRIMARY OBJECTIVES:. I. To determine whether ASA (acetylsalicylic acid) 325 mg inhibits prostaglandin E2 (PGE2) biosynthesis in patients with early stage non-small cell lung cancer (NSCLC). Cyclooxygenase (COX) catalytic activity will be determined by measuring the metabolite of PGE2, 11alpha-hydroxy-9,12-dioxo-2,3,4,5-tetranor-prostane-1,20 dioic acid (PGE-M) in urine pre- and post-ASA 325 mg as a surrogate of systemic PGE2 biosynthesis.. SECONDARY OBJECTIVES:. I. To determine whether COX-2 protein has a slow turnover in adenocarcinoma of the lung. COX turnover will be determined by measuring urinary PGE-M levels daily for 7 days after discontinuing ASA 325 mg. COX-2 and Prostaglandin expression will also be measured in tumor samples of patients taken at the time of surgery.. OUTLINE:. Patients receive acetylsalicylic acid orally (PO) for 7 days and urine is collected for 7 days post therapy. ...
Despite fresh evidence suggesting that a daily aspirin may lower risk of cancer death, researchers say its still soon to recommend taking the painkiller just for cancer prevention
Women who take aspirin regularly may have a reduced risk of breast cancer. However, previous studies have reported mixed results-some suggest risk is lowered with aspirin while others do not see a protective effect. Few of these studies have looked at whether this potential benefit of aspirin is linked to specific types of breast cancer. This study found a modest reduction in breast cancer risk for women who took a low-dose aspirin at least three times per week, but only for one subtype of breast cancer. Women who took aspirin were less likely to develop ER/PR-positive/Her2- negative breast cancer, the most common type of breast cancer. This study found no breast cancer risk reduction for women who used regular-dose aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDS). (8/29/17)
After five years of follow-up, a large Japanese study was cut short after finding no association between once-daily, low-dose aspirin and risk for heart attack, stroke or death. Published in the Journal of the American Medical Association, this study was designed to assess the impact of 100mg of aspirin a day on cardiovascular risk in the aging Japanese population. Almost 14,500 patients between the ages of 60 and 85 years old participated in the study, each of which had cardiovascular risk factors like high blood pressure, high cholesterol or diabetes but had not been diagnosed with heart disease. Half of patients were randomly assigned to take daily aspirin while the other half took an inactive pill called a placebo, in addition to any ongoing medications. After following patients for just longer than five years, the study was cut short when aspirin showed no significant benefit over the inactive placebo. Risk of heart attack, stroke and death was similar in the aspirin and placebo group and ...

AIMS: To examine the proportion of UK Prospective Diabetes Study (UKPDS) patients with Type 2 diabetes taking aspirin regularly for the primary and secondary prevention of cardiovascular disease (CVD) before and after publication of the 1997 American Diabetes Association (ADA) Clinical Practice Recommendations and the 1998 Joint British Recommendations on the Prevention of Coronary Disease in Clinical Practice. METHODS: UKPDS annual review data from 1996/7 (n = 3190) and 2000/1 (n = 2467) were used to determine the prevalence of patients taking aspirin regularly in relation to known CVD risk factors and pre-existing CVD. RESULTS: Patients taking aspirin regularly were more often male than female (24 vs. 20%, P = 0.0033), older (66 +/- 8 vs. 62 +/- 9 years, P < 0.0001) and less often Afro-Caribbean than White Caucasian or Indian Asian (11 vs. 23 vs. 22%, respectively, P < 0.0001). Between 1996/7 and 2000/1 aspirin use in patients without pre-existing CVD increased from 17 to 31% (P < 0.0001) and ...
Aspirin in patients undergoing noncardiac surgery. - Nuffield Department of Obstetrics and Gynaecology
BACKGROUND: There is substantial variability in the perioperative administration of aspirin in patients undergoing noncardiac surgery, both among patients who are already on an aspirin regimen and among those who are not. METHODS: Using a 2-by-2 factorial trial design, we randomly assigned 10,010 patients who were preparing to undergo noncardiac surgery and were at risk for vascular complications to receive aspirin or placebo and clonidine or placebo. The results of the aspirin trial are reported here. The patients were stratified according to whether they had not been taking aspirin before the study (initiation stratum, with 5628 patients) or they were already on an aspirin regimen (continuation stratum, with 4382 patients). Patients started taking aspirin (at a dose of 200 mg) or placebo just before surgery and continued it daily (at a dose of 100 mg) for 30 days in the initiation stratum and for 7 days in the continuation stratum, after which patients resumed their regular aspirin regimen.

It has been posited that aspirin treatment may reduce risk for colorectal cancer through inhibition of WNT/cadherin-associated protein β1 (CTNNB1, or β-catenin) signaling. In a study reported recently in the Journal of the National Cancer Institute, Nan et al investigated the potential role of the single nucleotide polymorphism rs6983267 (chromosome 8q24) in the protective effect of aspirin.1 This colorectal cancer susceptibility locus affects binding activity of transcription factor 7 like-2 (TCF7L2) to CTNNB1 and alters expression of target oncogenes, including MYC. The study showed that the T allele of rs6983267 was associated with a protective effect in regular aspirin users and was associated with reduced MYC expression.. The study involved investigation of regular aspirin use and colorectal cancer risk according to genotypes of rs6983267 and CTNNB1 expression in two prospective case-control studies within the Nurses Health Study (women) and the Health Professionals Follow-up Study ...

The researchers found that deaths related to cardiovascular disease occurred at essentially the same rate for people who did and did not take aspirin. There was a modest decrease in non-fatal heart attacks, but that benefit was almost entirely offset by a 30 percent increase in life-threatening or debilitating internal bleeding. This means that one stroke or heart attack was averted for every 120 people treated with aspirin, while one in 73 people taking aspirin suffered significant internal bleeding.. The lead author of the study emphasized that people with a history of heart conditions should not stop taking aspirin.. "The beneficial effect of aspirin on preventing future cardiovascular disease events in people with established heart attacks or strokes is indisputable," said Dr. Rao Seshasai of also from St Georges University of London. "However, the benefits of aspirin in those individuals not known to have these conditions are far more modest than previously believed and, in fact, aspirin ...
The new case-control study from Scotland is one of the largest to date to have specifically examined low dose aspirin, and provides some evidence that using low-dose aspirin for five or more years may also reduce colorectal cancer risk," said Jacobs, who was not involved in the research. "However, previous studies of low-dose aspirin and colorectal cancer have had mixed results, and results of this study need to be confirmed." The study also found that taking any NSAID regularly was associated with a reduced risk of colorectal cancer, compared to those who didnt use the painkillers. The subjects and controls had been matched for age, gender and locale as well as smoking, alcohol and fiber intake, and the findings held true even after results were adjusted for weight, body-mass index and other factors, according to the study, which was published in the current issue of the journal Gut ...
Effect of increased aspirin dose after stenting in association with ClOpidogrel: the FIASCO randomized study. - Semantic Scholar
BACKGROUND Increased doses of antiplatelet therapy have been proposed to overcome the variability of response. However, the chronic dose of aspirin after DES remains controversial. METHODS AND RESULTS We assessed in a prospective and randomized study the benefit of higher dose of aspirin, in association with clopidogrel, on aspirin response and non COX-specific platelet testing in patients receiving Drug Eluting Stent (DES) for stable angina pectoris. 50 consecutive patients receiving DES for stable angina pectoris were prospectively included. They received loading dose of 250 mg aspirin and 600 mg clopidogrel and antiplatelet response was assessed with Arachidonic Acid-induced aggregation (AA-Ag) and ADP-induced aggregation (ADP-Ag) for aspirin and clopidogrel response respectively. Patients were randomized to either 75 or 160 mg of aspirin with 150 mg clopidogrel and platelet testing were repeated one month after hospital discharge. The two groups (aspirin 75 mg or 160 mg) had no difference for
Rothwell and his colleagues followed over 3,100 patients for 10 years who were prescribed a daily aspirin after a heart attack or stroke. For the patients under 65, the annual rate of bleeding severe enough to require hospitalization was about 1.5 percent. For patients aged 75-84, the annual rate rose to 3.5 percent and for patients over 85 it was 5 percent.. The researchers are not recommending that seniors stop taking aspirin. But they suggest that a proton-pump inhibitor - heartburn drugs - be prescribed along with aspirin to reduce the risk of bleeding. They estimate that proton-pump inhibitors (PPIs) could reduce upper gastrointestinal bleeding by as much as 90% in patients receiving long-term aspirin treatment.. "While there is some evidence that PPIs might have some small long-term risks, this study shows that the risk of bleeding without them at older ages is high, and the consequences significant," said Rothwell.. About half of adults aged 75 or older in the U.S. and Europe take aspirin ...
Is it true? A baby Aspirin daily helps prevent vascular events (MI/Stroke) in all patients.. Bottom Line: Aspirin decreases the incidence of coronary heart disease in adults who are at increased risk for heart disease. There is also good evidence that aspirin increases the incidence of gastrointestinal bleeding and fair evidence that aspirin increases the incidence of hemorrhagic strokes. There is no evidence of MI prevention with low dose aspirin in general population with no risk factors. Low-dose aspirin prevents stoke events in women >45 years of age.. Review. Patients at increased risk for cardiovascular (CV) events benefit from low-dose aspirin, provided that the patient does not have major risk factors for gastrointestinal (GI) or cerebral bleed.1 The risk of aspirin-induced bleeding usually outweighs the benefit of reducing cardiovascular events in patient with minimal to no risk factors for CV events.2,3, The results of Womenâ€™s Health Study (WHS) demonstrated that in women >45 ...
According to a report by the U.S. Preventive Services Task Force, although daily aspirin intake can reduce the risk of coronary heart disease by up to 28% in patients who have never had a heart attack but who are at increased risk of coronary heart disease, the vast majority of healthy people may not derive such benefit. The increase in incidence of gastrointestinal bleeding and hemorrhagic stroke associated with daily aspirin intake may actually pose a greater risk for patients with low or even average risk of developing coronary heart disease. The Task Force, therefore, recommends that clinicians carefully evaluate cardiovascular risk factors for each patient and counsel on whether or not aspirin?s benefits outweigh its risks. ?For most people, daily aspirin does more harm than good ...
Seniors who take aspirin daily are twice as likely to have late stage macular degeneration, an age-related loss of vision, than people who never take the pain reliever, according to a European study. The data do not show that aspirin causes vision loss. But the findings, published in Opthalmology, are of concern if aspirin somehow exacerbates the eye disorder, given how many seniors take it daily for heart disease. "For people who have age-related macular degeneration, it probably isnt wise to recommend taking aspirin," said William Christen of Brigham and Womens Hospital in Boston, who was not involved in the study. Researchers led by Paulus de Jong at the Netherlands Institute for Neuroscience and Academic Medical Center collected health and lifestyle information from nearly 4700 people over age 65. The study included Norwegian, Estonian, British, French, Italian, Greek and Spanish seniors. Of the 839 people who took aspirin each day, 36 had an advanced form of the disease called wet macular ...
U.S., Feb. 10 -- According to a new study by a team of researchers from U.S. National Institute of Child Health and Human Development (NICHD), taking daily low dose of aspirin may lower the chances of miscarriage which can be very stressful for a couple. For the study, the researchers selected more than 1,200 women in the age group of 18-40 who had a miscarriage in the past. All the women were trying to conceive and 55 percent of the women had a live birth. All the women underwent a test to test blood level of C-reactive protein (CRP), a substance present in the blood that denotes systemwide inflammation. The researchers divided the women into two groups. One group received daily dose of aspirin (81 milligrams), while the other group received a placebo. The findings of the study revealed that aspirin may increase the chances of women with high levels of inflammation who have had a miscarriage in the past to give birth to a child again. The findings of the study were published in the Journal of ...
An international scientific meeting on aspirin is needed | Journal of Epidemiology & Community Health
Aspirin (acetylsalicylic acid) is inexpensive and widely used to treat numerous common conditions. Perhaps its most important use now is the reduction of the risk of cardiovascular disease morbidity and mortality. As with all medicines, there are undesirable effects to its use, most notably gastrointestinal irritation and bleeding. Low dose aspirin is comparatively safe, however, and in the reduction of cardiovascular disease risk the potential benefit must be balanced against potential risk.. Observational epidemiological studies suggest that the regular use of aspirin may lead to a reduced risk of several other diseases. This includes certain cancers, particularly those in the gastrointestinal tract, and the most persuasive evidence relates to colorectal cancer. At least seven randomised controlled trials to test the aspirin and colorectal cancer hypothesis have been set up and preliminary data from one of these trials are promising. Results from other trials are expected in the near ...

The findings provided in this report indicate that prevalence of prescribing aspirin or other antiplatelet medications at outpatient health-care visits is low for patients who have been recommended to receive these medications based on the presence of ischemic vascular disease or certain risk factors. Despite the low prevalence of aspirin prescribing identified in this analysis, other studies using the same data sources have demonstrated that aspirin and other antiplatelet medication prescribing among patients with ischemic vascular disease was only 32.8% in 2003 (16). Previous reports have estimated that for every 10% increase in the use of antiplatelet medication among eligible adults aged 18-79 years, an estimated 8,000 deaths per year would be prevented (21). A 2006 study that ranked clinical preventive services based on cost effectiveness and the clinically preventable burden of disease demonstrated that aspirin prevention counseling was one of three prevention services that received the ...

Should healthy people take aspirin to ward off heart disease? The notion has been controversial, and the medical advice mixed.. But a review of scientific data on the topic showed that any benefits are slight, and are counterbalanced by a matching rise in bleeding risks.. Aspirin is a blood thinner and can help prevent clots that may lead to heart attack or stroke. But aspirin also boosts the risk of hemorrhage in the brain, stomach and intestines.. "When considering the totality of evidence, cardiovascular benefits associated with aspirin were modest and equally balanced by major bleeding events," said the report in the Journal of the American Medical Association.. The meta-analysis examined 10 prior studies involving a total of more than 164,000 people with an average age of 62.. Comparing aspirin users to those who dont take aspirin, researchers found "significant reductions" in strokes, heart attacks and deaths from cardiovascular disease among those who took aspirin.. Aspirin use was also ...
Aspirin. This Patent Artwork collage captures the manufacture or production of Acetyl Salicylic Acid - aspirin. Aspirin can trace its roots back to the days of Hippocrates. In the 1800s researchers tried to strip down the pain relieving properties of the herbal remedy and had some success but with bad stomach side effects. Felix Hoffman had great success in refining a formulation that Charles Frederic Gerhardt tried but gave up on and was able to patent his formulation in the late 1800s. He worked for Bayer at the time, they gave it a brand name and thus Aspirin was born.. The word "Aspirin" (uppercase A), was originally a trademark of Bayer. The trademark and all IP was stripped from them as part of the Treaty of Versailles at the end of World War 1 because of their participation in the war and the name was "genericized" as aspirin (lower case A).. The contextual background used for this print mimics paper from a chemistry lab book.. This print appeals to MDs, pharmacists and chemists ...
The use of low dose aspirin may actually help an individual reduce his risk of developing pancreatic cancer, a new study has found
Getty Images. I was sitting down to watch the bowl games on New Years Day when the phone rang. It was my dad. A year ago, hed called to tell me he was being admitted to a hospital in Florida with a heart attack. Thankfully, this time it wasnt his heart. But once again, he was in the hospital. Hed noticed his bowel movements were black and he felt a little lightheaded: two hallmarks of a gastrointestinal bleed.. Why would my father, who is in his 80s but in very good health, have a GI bleed? Well, in a way it was related to his heart. After his heart attack, he had stents placed in two of his coronary arteries to improve blood flow. To prevent the stents from becoming blocked, his doctors prescribed daily aspirin.. Aspirin works in part by inhibiting the clotting effects of platelets - cells that make your blood sticky. When theres a nick in a blood vessel, or an irritation in your intestinal lining, platelets work with proteins in your blood to stop the bleeding.. Aspirin in your blood ...
Findings from two large prospective cohort studies indicated that long-term aspirin use was tied to a modest but significantly reduced risk for overall cancer, especially GI tract tumors.
In a recent study published in Health Technology Assessment, the risks and benefits of daily aspirin were assessed, showing that healthy people without risk of cardiovascular events should not take aspirin daily.
UNTHSC Scholarly Repository - Texas Health Disparities Conference: Low-dose aspirin during pregnancy does not prevent maternal...
Background: Daily low-dose aspirin after 12 weeks of gestation is recommended as a preventive intervention for women at high risk for preeclampsia. Treatment of pregnant rats with a specific ligand of the innate immune receptor Toll-like receptor 9 (TLR9) induces maternal hypertension and vascular dysfunction. Hypothesis: We hypothesized that maternal treatment with low-dose aspirin during gestation would ameliorate TLR9-induced hypertension and vascular dysfunction in pregnant rats. Methods: Pregnant rats were treated with a synthetic ligand of TLR9 (ODN2395) or saline (vehicle) during the third trimester. Aspirin treatment started on GD10 and continued throughout gestation. Experimental groups include: control (no treatment), ODN2395 (300 μg), aspirin (1.5 mg/kgBW), aspirin+ODN2395. Blood pressure was measured on GD19 and mesenteric artery function was assessed on GD21 using wire myography. Results: ODN2395-treated rats had higher blood pressure on GD19 compared to vehicle-treated dams and aspirin
A study has found that taking an aspirin a day could significantly reduce the risk of developing and dying from bowel, stomach and oesophageal cancer.. A team led by Professor Jack Cuzick, head of the centre for cancer prevention at Queen Mary University of London, conducted the research, which involved analysing evidence from studies and clinical trials to assess both the benefits and risks associated with taking aspirin to prevent cancer.. Currently there are two theories regarding how aspirin prevents cancer:. 1. Aspirin reduces inflammation, which lowers the risk of cancerous cells developing in the body (inflammation causes cells to divide which increases the risk of mutation). 2. 2. Cancer cells can attach to blood platelets, which help the blood to clot. As aspirin thins blood by making platelets less sticky, it may also make it harder for them to carry cancer cells and spread the disease.. The study concluded that taking aspirin for 10 years could cut bowel cancer cases by approximately ...
Preparation of aspirin - The chemical background This is the overall reaction that is going to be done to synthesise aspirin -...
Introduction. The Commercial Importance of Aspirin Introduction In 1899 Aspirin was first synthesised, and also known as acetylsalicylic acid which is the salicylate ester of ethnic acid. Salicylate origins lie in the naturally occurring compound salicin. It was discovered by the Greeks, around the fifth century B.C, that a substance in the bark of the willow tree, (we now know as salicin) could relieve pain. How does Aspirin work in the body? Aspirin is able to block the production of a substance called prostaglandins. These prostaglandins are produced by the body whenever a cell in the body is injured. Production and release of these prostaglandins leads to swelling, pain and fever which are commonly associated with injuries or disease. Medical uses of Aspirin There are so many medical uses of Aspirin, like: * It is known that aspirin reduces the risk of strokes in patients with early warning signs of Transient Ichaemic attacks. * It is now accepted as an important weapon in the prevention of ...

Inflammation has a role in heart disease and may also be implicated in aging brain. Daily low dose aspirin could slow the decline in brain power among elderly women at high risk of heart disease, indicates observational research published in the online journal BMJ Open.. The researchers base their findings on 681 women between the ages of 70 and 92, 601 of whom were at high risk of heart disease and stroke, defined as a 10% or greater risk on a validated risk scale (Framingham).. All the women were subjected to a battery of tests to measure their physical health and intellectual capacity, including verbal fluency and memory speed, and dementia (mini mental state exam, or MMSE for short) in 2000-1.. Their health was tracked over a period of five years, at the end of which the intellectual capacity of 489 women was assessed again.. Some 129 women were taking low dose aspirin (75 to 160 mg) every day to ward off a heart attack or stroke when the monitoring period started. A further 94 were taking ...
Aspirin is used to treat mild to moderate pain, and also to reduce fever or inflammation. It is sometimes used to treat or prevent heart attacks, strokes, and angina. Aspirin should be used for cardiovascular conditions only under the supervision of a doctor.
Abstract 12357: Enzyme Kinetic Model Reveals Novel Characteristics of Pharmacodynamic Interaction of NSAIDs and Aspirin at COX...
Introduction: Non-aspirin NSAIDs attenuate the antiplatelet action of aspirin leading to High on Aspirin Platelet Reactivity (HAPR). However, detailed features of this interaction are still unresolved. Both competitive as well as non-competitive interaction at the cyclooxygenase-1 (COX-1) enzyme have been proposed.. Hypothesis: We examined whether competitive enzyme kinetics describe COX-1 inhibition by aspirin and HAPR and if they are compatible with results obtained experimentally.. Methods: We have developed an enzyme kinetic model of the aspirin/NSAID interaction at COX-1 using mathematical modelling and have varied enzyme kinetic parameters to predict the occurrence and the extent of HAPR. Subsequently, the predictions obtained were experimentally verified with selected NSAIDs using light transmission aggregometry and immunoassay for platelet thromboxane (TX) synthesis.. Results: Enzyme kinetic modelling predicted that only low- and medium-affinity NSAIDs (Ki ≥1 μM), but not ...
Two reports this week have suggested that Aspirin may not be such a wonder drug after all.. One report published in the Jan 2012 issue of Ophthalmology indicated that regular Aspirin use may double the risk of Age Related Macular Degeneration (ARMD), and that there is an indication that the more frequent the use, the more severe the ARMD. More investigation needs to be done on this, but for the moment, there is a suggestion that Aspirin use should be reconsidered in people who already have ARMD.. Another study published in Jan 2010, in The Archives of Internal Medicine suggests that Aspirin is not so effective in preventing CardioVascular events as perhaps initially thought, likewise it may not have the preventative cancer protection suspected, but definitely increased the risks of "non trivial bleeding".. It may be worth asking your General Practitioner if this is of concern…. ...
... , A new report from British scientists suggests that long-term, daily aspirin use may modestly lower the risk of dying of certain cancers, though experts warn the study isnt strong enough to recommend healthy people start taking a pill that can cause bleeding and other problems.

New York, NY (PRWEB) September 26, 2019 -- High-risk patients undergoing coronary stent procedures may not require long-term aspirin use after stent
An aspirin a day keeps the ambulance at bay? Only if you swallow the right kind. Coated aspirin may not be as effective as plain aspirin at preventing coronary heart disease, according to a new study published in the journal Stroke. Researchers gave 71 healthy people different forms of aspirin to take for 2 weeks at a time, then tested their blood for thromboxane, a substance that contributes to blood clots. Levels were 87 percent lower among those taking plain aspirin than in those swallowing coated pills. "Doctors normally prescribe coated aspirin to protect the stomach lining," says lead study author Dermot Cox, Ph.D., "but the coating may impede absorption." Consider swallowing a 75- milligram uncoated pill. "It will provide all the benefits with the lowest chance of side effects," he says ...
DEAR MAYO CLINIC: Should I be taking a daily aspirin even if Ive never had heart issues? Im a 62-year-old woman with no health problems, and I exercise daily. My husband takes an aspirin every day
LONDON - Daily aspirin use may curb cancer-related deaths, according to a new study published in The Lancet. The study, led by Peter Rothwell of the University of Oxford and colleagues, analyzed data from eight eligible trials - which typically lasted about four years - and included more than 25,000 subjects. Among them, 674 died from cancer.
Dr. Philip Majerus, Among the First to Discern Aspirin's Heart Benefits, Dies at 79 | Flash News Updates
Photo Dr. Philip W. Majerus was one of the first to recommend that all adults take aspirin daily. Credit Washington University School of Medicine Philip W. Majerus, a biochemist who was credited as being the first to theorize that taking small doses of aspirin regularly can prevent heart attacks and strokes in vulnerable patients, died on June 8 at his home in St. Louis. He was 79.The cause was prostate cancer, his wife, Dr. Elaine Majerus, said. He had taught at the Washington University School of Medicine in St. Louis for almost 50 years.Even before his findings were confirmed in a study by other researchers a decade later, Dr. Majerus was taking aspirin daily.I was already convinced that aspirin prevented heart attacks, he recalled in the journal Advances in Biological Regulation in 2014. I was unwilling to be randomized into a trial where I might end up with the placebo. I refused to participate.Dr. Majerus recommended that all adults should take an aspirin daily unless they are among the few
The United Kingdom transient ischaemic attack (UK-TIA) aspirin trial: final results. | Journal of Neurology, Neurosurgery &...
From 1979-85, 2435 patients with a transient ischaemic attack or minor ischaemic stroke were randomly allocated to receive long term "blind" treatment with aspirin 600 mg twice daily (n = 815), aspirin 300 mg once daily (n = 806) or placebo (n = 814). No patient was lost to follow up. The "intention to treat" comparison included all the serious vascular events and deaths which occurred before the end of the follow up period on 30 September 1986. There was no difference in efficacy between the 300 mg and 1200 mg daily doses of aspirin, but the lower dose was undoubtedly less gastrotoxic. Also, there was no definite difference in the response of males and females to aspirin. The odds of suffering a major stroke, myocardial infarction or vascular death were 15% less in the combined aspirin groups compared with the placebo group (95% confidence interval 29% reduction to 3% increase in odds) which is compatible with the continuing overview of all the similar trials of antiplatelet drugs where the ...
Note* as with any item pertaining to your health, please seek the guidance of your doctor for dosages and any drug interactivity prior to taking any form of aspirin. Not just the same, old bitter pill anymore - aspirin again steals the limelight with its new found activity. It has been studied that bitter pill aspirin can decrease the risks of heart attacks and heart failures if taken at the bedtime. The American Health Association has declared that people who are diagnosed with heart disease can take small amounts of aspirin, regularly before going to bed. Aspirin, a drug of anti-pyretic and the analgesic genre had passed the taste of time since its innovation. It has served mankind over 100-years. The prevention of attacks has made aspirin surface and exposed the benefits of how they can help.. According to the researchers of a new study, aspirin lowers the chance of heart attack by 30 percent if taken regularly before going to bed. Even people suffering from normal health concerns can get ...
Background and Purpose-Long-term daily aspirin is of benefit in the years after ischemic stroke, and 2 large randomized trials (the Chinese Acute Stroke Trial [CAST] and the International Stroke Trial [IST]), with 20 000 patients in each, have shown that starting daily aspirin promptly in patients with suspected acute ischemic stroke also reduces the immediate risk of further stroke or death in hospital and the overall risk of death or dependency. However, some uncertainty remains about the effects of early aspirin in particular categories of patient with acute stroke.. Methods-To assess the balance of benefits and risks of aspirin in particular categories of patient with acute stroke (eg, the elderly, those without a CT scan, or those with atrial fibrillation), a prospectively planned meta-analysis is presented of the data from 40 000 individual patients from both trials on events that occurred in the hospital during the scheduled treatment period (4 weeks in CAST, 2 weeks in IST), with 10 ...
Taking a low-dose aspirin every day can help prevent heart attacks in people whove already had one. But if youve never had a heart attack (or stroke), the risks of taking a daily low-dose aspirin outweigh the benefits, according to a U.K. report published in Drug and Therapeutics Bulletin.
Aspirin and Colorectal Cancer Incidence and Mortality by CTNNB1 Expression: A Molecular Pathological Epidemiology (MPE) Study |...
Purpose: Experimental studies showed that aspirin down-regulates the WNT/CTNNB1 (β-catenin) signaling pathway in colon cancer cells. We investigated whether aspirin use was associated with lower incidence and superior survival in nuclear CTNNB1-positive colorectal cancer. Methods: In two large prospective studies (the Nurses Health Study and the Health Professionals Follow-up Study), we collected the information on aspirin use every 2 years from 1980 through 2008. We used Cox proportional hazards regression to compute the multivariate hazard ratio for incidence and mortality according to tumor CTNNB1 expression patterns. Results: During 28 years and 3,166,091 person-years of follow-up, we documented 931 incident cases of colorectal cancer with available CTNNB1 expression data. Regular aspirin use was associated with a significantly lower risk of CTNNB1-positive cancer (multivariate HR = 0.65; 95% CI, 0.53-0.80), but not with the risk of CTNNB1-negative cancer (multivariate HR = 0.84; 95% CI, ...
A daily dose of aspirin has long been touted as a means of preventing heart attacks and strokes. While aspirin is a proven methodology for some heart patients, there can be issues with aspiring for others. In fact, new research shows that many Americans are inappropriately downing a daily dose.. An estimated 69,000 American adults have been prescribed a long-term daily aspirin regime to preclude cardiovascular problems. However, the research team determined that 12 percent of them should not be taking the aspirin.. The researchers, led by Dr. Ravi Hira, a cardiologist from Baylor College of Medicine in Houston, found that the aspirin use was creating risks of other problems that overshadowed the risks of heart issues. Overuse of aspirin is known to cause serious gastrointestinal bleeding or hemorrhagic stroke (bleeding in the brain) as side effects.. Published online in the Journal of the American College of Cardiology, the study is based on medical records from over 68,800 patients at 119 U.S. ...
Doctors should be encouraging their patients to use aspirin on a regular basis in an effort to save lives, according to a national organization.
Aspirin use is down among women with diabetes, according to a study reported in the Archives of Internal Medicine (December 13, 2004). The study found that in adult patients with diabetes who do not have cardiovascular disease, 42% of men and 34% of women take aspirin regularly. Researchers at Northwestern University offered several explanations for low aspirin use among women. For example, physicians may not counsel women with diabetes to take aspirin if the physicians underestimate the womens risk for cardiovascular disease events. One of the investigators said, "However, even though women are at lower risk of new-onset cardiovascular disease than men, diabetes greatly reduces this female advantage." ...

By Shereen Lehman(Reuters Health) - Stopping low-dose aspirin therapy without good reason raises the likelihood of heart attack or stroke by nearly 40 percent, a large Swedish study suggests.Doctors commonly prescribe daily low-dose aspirin after a heart attack to reduce the risk of having a second cardiovascular event. But about one in six patients stop taking their aspirin within three years, the study authors note in Circulation.
US researchers examined diet, lifestyle and medication history from 59,806 women aged 50-79 for an average of 12 years and recorded any cases of cancer. Data revealed the women, who were part of the Womens Health Initiative, showed those who took more aspirin were less likely to develop melanoma. ASPIRIN may offer protection from melanoma in women, a study has found, adding to the body of evidence supporting the potential role of aspirin in cancer prevention.

Two cases of wheat-dependent anaphylaxis induced by aspirin administration but not by exercise. - Semantic Scholar
BACKGROUND Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) have been reported to enhance the symptoms of wheat-dependent exercise-induced anaphylaxis (WDEIA). In contrast to many reports on WDEIA, there have been only a few reports of wheat-dependent aspirin-induced anaphylaxis not induced by the combination of wheat and exercise. METHODS Two patients with wheat-dependent anaphylaxis underwent provocation tests to clarify the cause of their symptoms. Skin-prick testing (SPT) was also performed with and without administration of aspirin. Specific IgE antibody to wheat, gluten, and omega-5 gliadin were examined. RESULTS In the provocation tests, anaphylactic reactions were not induced by wheat or aspirin alone or by the combination of wheat and exercise, but were induced by the combination of wheat and aspirin. An increase in the blood histamine level was detected after provocation in both patients. Pretreatment with aspirin enhanced the SPT reactions to wheat and gluten in both

Background: Chronic kidney disease (CKD) is a strong risk factor for cardiovascular events, and there are consistence evidences about worse short- and long-term outcomes in CKD patients with acute myocardial infarction. The aim of this study was to evaluate the effects and safety of triple antiplatelet therapy (aspirin plus clopidogrel plus cilostazol) in CKD patients with ST-elevation myocardial infarction (STEMI) compared with dual antiplatelet therapy (aspirin plus clopidogrel).. Methods and results: Among over 21,000 patients in Korean Acute Myocardial Infarction Registry (KAMIR) data, 5,138 STEMI patients who underwent successful primary percutaneous coronary intervention with drug-eluting stents were enrolled in this study. They were divided by estimated creatinine clearance (eCrCl); ≥ 60 ml/min (n=3,445; dual = 2169, triple = 1276) and , 60 ml/min (n=1693; dual = 1120, triple = 573). Various major adverse cardiac events including major bleeding at 12 months were evaluated. The triple ...

TY - JOUR. T1 - Aspirin Idiosyncrasy in Systemic Mast Cell Disease. T2 - A New Look at Mediator Release During Aspirin Desensitization. AU - Butterfield, Joseph H.. AU - Kao, Pai C.. AU - Klee, George G.. AU - Yocum, Michael W.. PY - 1995/1/1. Y1 - 1995/1/1. N2 - To report the clinical responses and mediator-release profiles of an aspirin-sensitive man with systemic mast cell disease during aspirin desensitization. We quantified the release of six mediators during aspirin desensitization. Although aspirin was administered cautiously with an initial dose of 20 mg, successful aspirin desensitization necessitated complete monitoring and resuscitation capabilities of a medical intensive-care unit for 4.5 days because of frequent, severe anaphylactoid responses. To our knowledge, this is the first report of a pronounced increase in plasma levels of the vasodilator peptide calcitonin gene-related peptide during episodes of aspirin-induced hypotension. Increases in plasma levels of calcitonin and serum ...
Published on: March 2, 2012. by Dr Ananya Mandal, MD for News Medical:. A new study finds that older women who take in substantial amount of trans fats are more likely than their counterparts to suffer an ischemic stroke.. However, the risk of stroke associated with trans fat intake was lower among women taking aspirin, according to the findings from University of North Carolina at Chapel Hill researchers. The report, "Trans Fat Intake, Aspirin and Ischemic Stroke Among Postmenopausal Women," was published today online in the journal Annals of Neurology.. Researchers from the UNC Gillings School of Global Public Health studied women who were enrolled in the Womens Health Initiative Observational Study. From 1994 to 2005, 1,049 new cases of ischemic stroke were documented.. The researchers looked at 87,025 generally healthy postmenopausal women aged 50 to 79 found that those whose diets contained the largest amounts of trans fats were 39 percent more likely to have an ischemic stroke (clots in ...
... Cochrane Database Syst Rev. 2008;(3):CD000029. Authors: Sandercock PA, Counsell C, Gubitz GJ, Tseng MC. BACKGROUND: In patients with acute ischaemic stroke, platelets become activated. Antiplatelet therapy might reduce the volume of brain damaged by ischaemia and reduce the risk of early recurrent ischaemic stroke. This might reduce the risk of early death and improve long-term outcome in survivors. However, antiplatelet therapy might also increase the risk of fatal or disabling intracranial haemorrhage. OBJECTIVES: To assess the efficacy and safety of antiplatelet therapy in acute ischaemic stroke. SEARCH STRATEGY: We searched the Cochrane Stroke Group Trials Register (last searched June 2007), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2007), MEDLINE (June 1998 to May 2007), and EMBASE (June 1998 to May 2007). In 1998, for a previous version of this review, we searched the register of the ...

Objectives The PLATO (PLATelet inhibition and patient Outcomes) PLATELET substudy aimed to compare the antiplatelet effects of clopidogrel and ticagrelor in patients with acute coronary syndromes. Background The PLATO study demonstrated superiority of ticagrelor over clopidogrel in the prevention of ischemic events in patients with acute coronary syndromes. Methods Patients were randomized to receive either clopidogrel (300- to 600-mg loading dose [LD], 75 mg/day) or ticagrelor (180-mg LD, 90 mg twice daily). The effects of maintenance therapy were studied in 69 patients pre- and 2 to 4 h post-dose after at least 28 days. The LD effect was studied in 24 clopidogrel-naive patients. Light transmittance aggregometry (adenosine diphosphate 5 to 20 mu M), VerifyNow P2Y12, and VASP phosphorylation assays were performed. Results During maintenance therapy, ticagrelor achieved greater suppression of platelet reactivity compared with clopidogrel. The mean maximum light transmittance aggregometry ...
Use of a haemostatic matrix (Floseal(®)) does not reduce blood loss in minimally invasive total knee arthroplasty performed...
BACKGROUND: Aspirin is being used for primary and secondary cardiovascular prevention. It has been proposed that aspirin should be discontinued 5 to 7 days before surgery. However, discontinuation might increase the risk of cardiac and thrombo-embolic co-morbidity. Aspirin also increases the risk of bleeding during and after total knee arthroplasty. This study evaluated if the intra-articular use of a haemostatic matrix (Floseal®) might decrease blood loss in total knee arthroplasty performed under continued aspirin use. MATERIALS AND METHODS: We retrospectively compared matched pairs in two groups (80 patients in each group). Patients in both groups were taking aspirin: one group was managed with conventional haemostasis (with bovie electrocoagulation), while the other group was treated with an intra-articular haemostatic matrix as an adjunct to electrocoagulation. The outcomes compared were haemoglobin and haematocrit levels at days 2 and 4 after surgery as surrogates for blood loss, ...

Benzene, C6H6, is the simplest aromatic hydrocarbon, and it was the first one named as such. The nature of its bonding was first recognized by August Kekulé in the 19th century. Each carbon atom in the hexagonal cycle has four electrons to share. One goes to the hydrogen atom, and one to each of the two neighbouring carbons. This leaves one electron to share with one of the two neighbouring carbon atoms, thus creating a double bond with one carbon and leaving a single bond with the other, which is why the benzene molecule is drawn with alternating single and double bonds around the hexagon. The structure is alternatively illustrated as a circle around the inside of the ring to show six electrons floating around in delocalized molecular orbitals the size of the ring itself. This depiction represents the equivalent nature of the six carbon-carbon bonds all of bond order 1.5; the equivalency is explained by resonance forms. The electrons are visualized as floating above and below the ring with the ...
