Atrial Fibrillation: a Patient's Guide to Understanding Drug Therapy
Ragini S. Bhakta
Journal of Atrial Fibrillation , 2008, DOI: doi: 10.4022/jafib.v1i4.515
Abstract: Atrial Fibrillation (AF) as defined by the American Heart Association is an irregular heart beat (rhythm) where the small upper chambers of the heart (atria) beat ineffectively. The atria cannot pump all of the blood out of the chambers, resulting in pooling of the blood or clot formation. Unfortunately, if a part of the clot leaves the atria, it can become lodged in an artery in the brain resulting in an ischemic stroke.

Abstract: Nanotechnology has the potential to offer solutions to these current obstacles in cancer therapies, because of its unique size and large surface-to-volume ratios. Nanoparticles may have properties of self-assembly, stability, specificity, drug encapsulation and biocompatibility as a result of their material composition. Nanoscale devices have impacted cancer biology at three levels: early detection, tumour imaging using radiocontrast nanoparticles or quantum dots; and drug delivery using nanovectors and hybrid nanoparticles. Other role of nanotechnology, in management of various diseases and also in drug resistance in leukemia by blocking drug efflux from cancer cells and induce efficient delivery of siRNA into lymphocytes to block apoptosis in sepsis and targeting tumors also. Nanocrystals labeling with immune cells can act as a platform technology for nanoimmunotherapy. This review addresses the advancement of nanoparticles in drug delivery and in cancer therapy.

Rika Shimada, Yasuaki Dohi, Kazunori Kimura, Satoshi Fujii
Pharmacology & Pharmacy (PP) , 2015, DOI: 10.4236/pp.2015.63014
Abstract: A 32-Item Japanese Medication Adherence Scale had been developed as a tool for evaluating the medication-taking behavior of hypertensive patients and predicting therapeutic efficacy, and an Internet survey of 990 hypertensive patients throughout Japan was performed. As a result, factor 1 “Expectation of pharmacological efficacy” (9 items), factor 2 “Motivation to be self-controlled in taking medication” (6 items), and factor 3 “Negative feelings about taking medication” (4 items) were identified, comprising a total of 19 items. The scale was highly reliable. Because it proved capable of discriminating between the 2 groups with different medication-taking status and blood pressure, its validity had also been confirmed.

Abstract: Hypertension, elevated blood pressure, is a noteworthy public health concern worldwide due to its significant contribution to the global health burden and its role as a prominent risk factor for the development of a number of disease processes. The control of blood pressure is required in patients with hypertension to produce the maximum reduction in clinical cardiovascular end points, especially in patients with co-morbidities like diabetes mellitus where more aggressive blood pressure lowering might be beneficial. Recent clinical trials suggest that the approach of using monotherapy for the control of hypertension is not likely to be successful in most patients. Combination therapy may be theoretically favoured by the fact that multiple factors contribute to hypertension, and achieving control of blood pressure with single agent acting through one particular mechanism may not be possible. Combining the drugs makes them available in a convenient dosing format, lower the dose of individual component, thus, reducing the side effects and improving compliance.

Abstract: polypharmacy, the state of being prescribed or taking more medications than clinically appropriate, can result in a variety of negative outcomes for both patients and healthcare facilities. these include negative outcomes such as adverse drug effects, hospitalizations, and poor patient health, as well as economic outcomes such as increased drug cost and costs associated with increased utilization of health services. available data suggests pharmacists have the potential to have a large effect in combating this problem through a variety of interventions such as reducing the number of medications taken, reducing the number of doses taken, increasing patient adherence, preventing adverse drug reactions (adrs), improving patient quality of life and decreasing facility and drug costs. a small number of studies have been performed on the pharmacists? role in addressing the problem of polypharmacy; however, they include various populations, settings, and measured outcomes. furthermore, some of the results are conflicting. nonetheless, this review of the available literature concludes that pharmacist interventions can improve patient outcomes. with the ever-increasing costs of healthcare, the substantial cost savings for patients as well as institutions provided by these interventions are further justification for widespread implementation of pharmacist interventions at healthcare institutions.
