Atrial fibrillation in patients undergoing surgical revascularization: an update on pharmacologic prophylaxis.
Authors: Rostagno C Abstract Atrial fibrillation occurs in 20-50% of patients after surgical revascularization (40% have more than 1 episode), with a peak between 2nd and 3rd postoperative days. Postoperative atrial fibrillation (POAF) has been associated with an increase in adverse events, length of hospital stay and, therefore, cost of care, and late mortality. A higher risk profile in patients who develop POAF may contribute to the higher late mortality rate. The pathogenesis of PAOF is multi factorial: transient ischemia during surgical procedure, neurohormonal activation, electrolyte imbalance, fluid overload ...

Does ongoing general practitioner care in elderly patients help reduce the risk of unplanned hospitalization related to Beers potentially inappropriate medications?
ConclusionsIncreased requirement for ongoing GP contact in less healthy elderly people appears to help minimize their risk of unplanned hospitalization due to PIM‐related harm. GPs should continue to avoid Beers medications in older patients where possible, given their greater predisposition to medication exposure (including PIM) and adverse drug events. Nevertheless, close monitoring of elderly patients who need to use PIM should prove beneficial. Geriatr Gerontol Int 2014; ●●: ●●–●●. (Source: Geriatrics and Gerontology International)

Cardiovascular Risk with Non-steroidal Anti-inflammatory Drugs: Clinical Implications
Abstract In February 2014, the US Food and Drug Administration (FDA) convened an advisory committee meeting to discuss the accumulated data relating to the cardiovascular risk of non-steroidal anti-inflammatory drugs (NSAIDs) and the potential implications on the class prescription labeling. The committee recommended, though not unanimously, that (1) the current data does not support the conclusion that naproxen has a lower risk of thrombotic events than other NSAIDs; (2) there is no latency period for the risk of cardiovascular thrombotic events; (3) there are some patient populations at increased risk for event...

Prophylaxis for acute gout flares after initiation of urate-lowering therapy
This review summarizes evidence relating to prophylaxis for gout flares after the initiation of urate-lowering therapy (ULT). We searched MEDLINE via PubMed for articles published in English from 1963 to 2013 using MEsH terms covering all aspects of prophylaxis for flares. Dispersion of monosodium urate crystals during the initial phase of deposit dissolution with ULT exposes the patient to an increased rate of acute flares that could contribute to poor treatment adherence. Slow titration of ULT might decrease the risk of flares. According to the most recent international recommendation, the two first-line options for prop...

Improvement of catalytic activity of lipase in the presence of calixarene valeric acid or hydrazine derivative.
Abstract Sol-gel encapsulation is a simple but powerful method to enhance the enantioselectivity of lipase-catalyzed transformations in an isooctane/aqueous buffer solution. Candida rugosa lipase was encapsulated according to a sol-gel procedure in the presence and absence of calixarene hydrazine or carboxylic acid derivatives with Fe3O4 magnetic nanoparticles as an additive. The activity of the encapsulated lipases was evaluated for the enantioselective hydrolysis of racemic Naproxen methyl ester and the hydrolysis of p-Nitrophenylpalmitate. The results indicate that the encapsulated lipase without calixaren...

Recurrent angioedema after naproxen use in a patient stabilized with losartan
Allergic reactions that result from concomitant drug use are understood yet potentially overlooked risk factors for angioedema. Nonsteroidal anti-inflammatory drugs (NSAIDs) in particular have been noted to trigger angioedema in patients with associated risk who are stabilized with other agents.1,2 Previous reports have described cases of angioedema after NSAID administration in patients stabilized on angiotensin-converting enzyme (ACE) inhibitors; however, detailed reports in patients receiving angiotensin receptor blockers (ARBs) are lacking.

Abstract 2126: PIK3CA mutation status is not involved in the response of nonsteroidal anti-inflammatory drugs in colorectal cancer cell lines
Nonsteroidal anti-inflammatory drugs (NSAIDs) have shown a chemopreventive effect for colorectal cancer (CRC) in many epidemiological and large scale population studies. Moreover, regular use of NSAIDs has been recently associated with a reduction in the recurrence rate of CRC in patients previously diagnosed with colorectal tumors harboring PIK3CA mutations in two different retrospective analyses of large clinical cohorts. However, the mechanism by which PIK3CA mutations interacts with the mechanism of action of NSAIDs remains elusive. Our aim was to investigate the contribution of the most common alterations detected in ...

Prevention and Treatment of NSAID Gastropathy
Opinion statement Nonsteroidal anti-inflammatory drug (NSAID) treatment will be necessary as part of our therapeutic armamentarium for many years to come. Therefore, safe prescription is mandatory in order to prevent adverse events. In the last two decades, new strategies and new drugs have been developed to reduce NSAID-associated upper gastrointestinal (GI) adverse events. Although the implementation of guidelines into clinical practice takes time, several studies have shown a recent and profound decrease in hospitalizations due to upper GI complications, which has been linked to widespread use of proton pump in...

Molecular interactions between some non-steroidal anti-inflammatory drugs (NSAID׳s) and bovine (BSA) or human (HSA) serum albumin estimated by means of isothermal titration calorimetry (ITC) and frontal analysis capillary electrophoresis (FA/CE).
Abstract The interactions between some non-steroidal anti-inflammatory drugs, NSAIDs, (naproxen, ibuprofen and flurbiprofen) and bovine (BSA) or human (HSA) serum albumin have been examined by means of two complementary techniques, isothermal titration calorimetry (ITC) and frontal analysis/capillary electrophoresis (FA/CE). It can be concluded that ITC is able to measure with high precision the strongest drug-albumin interactions but the higher order interactions can be better determined by means of FA/CE. Then, the combination of both techniques leads to a complete evaluation of the binding profiles between the s...

Cardiovascular Pharmacogenetics of Anti-Thrombotic Agents and Non-Steroidal Anti-Inflammatory Drugs.
Abstract The use of antithrombotic agents, particularly antiplatelet drugs like aspirin and clopidogrel, has been instrumental in decreasing the risk for adverse cardiovascular events across a wide range of patients. However, despite the established benefits, the use of these medications remains suboptimal. There is a high degree of inter-individual variation in response to these treatments, whereby patients experience occlusive thromboembolic events, in spite of maintaining an appropriate treatment regimen. This has lead to the notion of antithrombotic "resistance" or "poor responders", which has been a growing co...

A novel naproxen derivative capable of displaying anti-cancer and anti-migratory properties against human breast cancer cells
Conclusion: In this study we report that a naproxen-derivative (4) has powerful anti-inflammatory and anti-tumor properties as it induces appreciable amount of apoptosis in breast cancer cell line, and can also delay migration of cancer cells (MDA-MB-231) which would in turn delay cancer cell invasion and formation of secondary tumours in primary breast cancer patients. Thus, we propose that 4 is worthy of further investigation due to its potential as a therapeutic agent in anti-tumor treatment regimen. (Source: BMC Cancer)

Oral administration of whole dihomo-γ-linolenic acid-producing Saccharomyces cerevisiae suppresses cutaneous inflammatory responses induced by croton oil application in mice.
In this study, we investigated the efficacy of oral intake of heat-killed whole DGLA-producing yeast cells in the absence of lipid purification on cutaneous inflammation. Topical application of croton oil to mouse ears induces ear swelling in parallel with the increased production of chemokines and accumulation of infiltrating cells into the skin sites. These inflammatory reactions were significantly suppressed in a dose-dependent manner by oral intake of the DGLA-producing yeast cells for only 7 days. This suppression was not observed by the intake of the γ-linolenic acid-producing (C18:3n-6, an immediate precursor of D...

Druggists and pharmacists as gatekeepers: Sales routines and compliance with sales protocols for over-the-counter naproxen 275mg medicines in the Netherlands
Over the last decades, the sales of medicines has largely been shifted from prescription drugs to over-the-counter (OTC), non-prescription medicines. In 2008, for the first time ever, the growth in the sales OTC medicines exceeded the sales of prescription medicines . Instead of going to the doctor for a specific medicine, more and more medicines are available without a prescription in a pharmacy or drugstore. On the one hand this eases the pressure on doctors and the health care system, but on the other hand people may abuse medicines more easily. (Source: Health Policy)

Combination of tocolytic agents for inhibiting preterm labour.
CONCLUSIONS: It is unclear whether a combination of tocolytic drugs for preterm labour is more advantageous for women and/or newborns due to a lack of large, well-designed trials including the outcomes of interest. There are no trials of combination regimens using widely used tocolytic agents, such as calcium channel blockers (nifedipine) and/or oxytocin receptor antagonists (atosiban). Further trials are needed before specific conclusions on use of combination tocolytic therapy for preterm labour can be made.

Cholestatic hepatic injury associated with vismodegib, aspirin, and naproxen use: a case study and review of vismodegib safety
ConclusionsHerein, we describe a potential serious adverse effect associated with vismodegib use. Whether the illness is directly attributable to the medication or the result of drug‐drug interactions between vismodegib and NSAIDs, practitioners should be aware of the possibility of hepatic injury in patients on vismodegib. Furthermore, patients need to be informed of the potential risks of vismodegib and should be monitored closely to ensure that life‐threatening complications of treatment are avoided.
