To characterize the changes in bone mass with age in women and men, explain the physiology and pathophysiology of the bone remodeling process, identify the targets for prescription osteoporosis drugs in this process, and provide details about the uses, efficacy, safety, and economics of prescription drug therapies for osteoporosis prevention and treatment. Preventing accelerated bone loss and decreasing age-related decreases in bone density are the primary goals of prescription drug therapy for osteoporosis. Bisphosphonates are the drugs of choice for preventing and treating postmenopausal osteoporosis. Alternatives for patients who cannot take bisphosphonates include raloxifene and calcitonin salmon. Menopause is accompanied by a rapid loss in bone mass that is followed by annual losses due to aging in women, which are similar to age-related bone mass decreases in men. Most prescription drug therapies for osteoporosis prevention or treatment reduce bone resorption by inhibiting osteoclast activation and activity, with only one medication class able to increase bone formation by stimulating osteoblasts. Denosumab, an investigational monoclonal antibody that inhibits nuclear factor kB ligand, would be a new class of anti-resorptive medications. Bisphosphonates currently are the drugs of choice for preventing and treating osteoporosis, with 7- and 10-year safety data available for risedronate and alendronate, respectively. Weekly and monthly regimens of bisphosphonates improve patient acceptance. Recently, an injectable form of ibandronate received U.S. Food and Drug Administration approval for once every 3 months administration. Raloxifene and calcitonin salmon are alternatives for patients who cannot take bisphosphonates because of contraindications or adverse effects. Teriparatide, a recombinant parathyroid hormone fragment, not only increases bone mineral density but also increases bone connectivity. Osteoporosis medications are usually safe, especially if used

A recent meta-analysis suggested that opioid substitution therapy (OST) increased uptake of antiretroviral treatment (ART) and HIV viral suppression. We modelled whether OST could improve the HIV prevention benefit achieved by ART among people who inject drugs (PWID). We modelled how introducing OST could improve the coverage of ART across a PWID population for different baseline ART coverage levels. Using existing data on how yearly HIV-transmission risk is related to HIV plasma viral load, changes in the level of viral suppression across the population were used to project the relative reduction in yearly HIV-transmission risk achieved by ART, with or without OST, compared with if there was no ART - defined here as the prevention effectiveness of ART. Owing to OST use increasing the chance of being on ART and achieving viral suppression if on ART, the prevention effectiveness of ART for PWID on OST (compared with PWID not on OST) increases by 44, 31, or 20% for a low (20%), moderate (40%), or high (60%) baseline ART coverage, respectively. Improvements in the population-level prevention effectiveness of ART are also achieved across all PWID, compared with if OST was not introduced. For instance, if OST is introduced at 40% coverage, the population-level prevention effectiveness of ART could increase by 27, 20, or 13% for a low (20%), moderate (40%), or high (60%) baseline ART coverage, respectively. OST could improve the HIV prevention benefit of ART; supporting strategies that aim to concurrently scale-up OST with ART.

Interest in the use of antiretroviral therapy (ART) for prevention stems from mounting evidence from research studies demonstrating that ART is associated with a decrease in sexual HIV transmission among serodiscordant couples and, perhaps, in other populations at risk. There is paucity of data on the efficacy of ART for prevention in key populations, including persons who inject drugs (PWID). In this paper, we examine the current status of HIV services for PWID in Central Asia, the use of ART by this population and explore ART for prevention for PWID in this context. We also discuss research and implementation questions with relevance to such a strategy in the region. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Atrial fibrillation (AF), the most common and rising disorder of cardiac rhythm, is quite difficult to control and/or to treat. Non pharmacological therapies for AF may involve the use of dedicated pacing algorithms to detect and prevent atrial arrhythmia that could be a trigger for AF onset. Selection 900E/AF2.0 Vitatron DDDRP pacemaker (1) keeps an atrial arrhythmia diary thus providing detailed onset reports of arrhythmias of interest, (2) provides us data about the number of premature atrial contractions (PACs) and (3) plots heart rate in the 5 minutes preceding the detection of an atrial arrhythmia. Moreover, this device applies four dedicated pacing therapies to reduce the incidence of atrial arrhythmia and AF events. To analyze the reliability to record atrial arrhythmias and evaluate effectiveness of its AF preventive pacing therapies. We enrolled 15 patients (9 males and 6 females, mean age of 71+/-5 years, NYHA class I-II), with a DDDRP pacemaker implanted for a "bradycardia-tachycardia" syndrome, with advanced atrioventricular conduction disturbances. We compared the number and duration of AF episodes' stored in the device with a contemporaneous 24h Holter monitoring. After that, we switched on the atrial arrhythmias detecting algorithms, starting from an atrial rate over 180 beats per minute for at least 6 ventricular cycles, and ending with at least 10 ventricular cycles in sinus rhythm. Thereafter, in order to evaluate the possible reduction in PACs number and in number and duration of AF episodes, we tailored all the four pacing preventive algorithms. Patients were followed for 24+/-8 months (from 20 to 32 months). All 59 atrial arrhythmia episodes occurred in the first part of this trial, were correctly recorded by both systems, with a correlation coefficient (r) of 0.96. During the follow-up, we observed a significant reduction not only in PACs number (from 83+/-12/day to 2.3+/-0.8/day) but also in AF episodes (from 46+/-7/day to 0.12+/-0.03/day

Full Text Available Leprosy (Hansen’s disease is a chronic granulomatous bacterial infection mainly affecting the skin and peripheral nervous system yet also involving other organs and systems as a result of a pathological process. The causative agent of leprosy - Mycobacterium leprae - is an obligate intracellular microorganism. Despite the removal of a threat of a leprosy epidemic, European countries still record outbreaks of the disease mainly among migrants coming from endemic areas. A golden standard of the treatment of leprosy is a WHO-recommended combined drug therapy comprising drugs such as dapsone, clofazimine and rifampicin. The article provides current data on the mechanisms of action, efficacy and safety of these drugs and their combined scheme of treatment obtained as a result of clinical trials. Moreover, it also reviews new regimens of the drug therapy of leprosy including those with the use of drugs from the group of fluoroquinols as well as immunotherapy of the disease.
Full Text Available Abstract Background Drugs to protect the liver are frequently prescribed in some countries as part of treatment for tuberculosis. The biological rationale is not clear, they are expensive and may do harm. We conducted a systematic review to a describe the ingredients of "liver protection drugs"; and b compare the evidence base for the policy against international standards. Methods We searched international medical databases (MEDLINE, EMBASE, LILACS, CINAHL, Cochrane Central Register of Controlled Trials, and the specialised register of the Cochrane Infectious Diseases Group and Chinese language databases (CNKI, VIP and WanFang to April 2007. Our inclusion criteria were research papers that reported evaluating any liver protection drug or drugs for preventing liver damage in people taking anti-tuberculosis treatment. Two authors independently categorised and extracted data, and appraised the stated methods of evaluating their effectiveness. Results Eighty five research articles met our inclusion criteria, carried out in China (77, India (2, Russia (4, Ukraine (2. These articles evaluated 30 distinct types of liver protection compounds categorised as herbal preparations, manufactured herbal products, combinations of vitamins and other non-herbal substances and manufactured pharmaceutical preparations. Critical appraisal of these articles showed that all were small, poorly conducted studies, measuring intermediate outcomes. Four trials that were described as randomised controlled trials were small, had short follow up, and did not meet international standards. Conclusion There is no reliable evidence to support prescription of drugs or herbs to prevent liver damage in people on tuberculosis treatment.

interesting strategies, including >65 new patents issued during the past 2 years for approaches to local drug delivery focused on preventing restenosis. Restenosis after intraluminal or open vascular reconstruction remains an important clinical problem. Success in the coronary circulation has not translated into solutions for the peripheral arteries. However, our literature review reveals a number of promising approaches, including drug-eluting balloons, periadventitial drug delivery, and targeted systemic therapies. These and other innovations suggest that the future is bright and that a solution for preventing restenosis in peripheral vessels will soon be at hand. Copyright © 2013 Society for Vascular Surgery.

New drugs aiming at the development of targeted therapies have been assayed in combination with ionizing radiation over the past few years. The rationale of this concept comes from the fact that the cytotoxic potential of targeted drugs is limited, thus requiring concomitant association with a cytotoxic agent for the eradication of tumor cells. Conversely a low level of cumulative toxicity is expected from targeted drugs. Most targeted drugs act through inhibition of post-translational modifications of proteins, such as dimerization of growth factor receptors, prenylation reactions, or phosphorylation of tyrosine or serine-threonine residues. Many systems involving the proteasome, neo-angiogenesis promoters, TGF-β, cyclooxygenase or the transcription factor NF-κB, are currently under investigation in hopes they will allow a control of cell proliferation, apoptosis, cell cycle progression, tumor angiogenesis and inflammation. A few drugs have demonstrated an antitumor potential in particular phenotypes. In most instances, however, radiation-drug interactions proved to be strictly additive in terms of cell growth inhibition or induced cell death. Strong potentiation of the response to radiotherapy is expected to require interaction with DNA repair mechanisms. (authors)

To estimate the effects of needle and syringe programmes (NSP) and opioid substitution therapy (OST), alone or in combination, for preventing acquisition of hepatitis C virus (HCV) in people who inject drugs (PWID). Systematic review and meta-analysis. Bibliographic databases were searched for studies measuring concurrent exposure to current OST (within the last 6 months) and/or NSP and HCV incidence among PWID. High NSP coverage was defined as regular NSP attendance or ≥ 100% coverage (receiving sufficient or greater number of needles and syringes per reported injecting frequency). Studies were assessed using the Cochrane risk of bias in non-randomized studies tool. Random-effects models were used in meta-analysis. We identified 28 studies (n = 6279) in North America (13), United Kingdom (five), Europe (four), Australia (five) and China (one). Studies were at moderate (two), serious (17) critical (seven) and non-assessable risk of bias (two). Current OST is associated with 50% [risk ratio (RR) =0.50, 95% confidence interval (CI) = 0.40-0.63] reduction in HCV acquisition risk, consistent across region and with low heterogeneity (I 2 = 0, P = 0.889). Weaker evidence was found for high NSP coverage (RR = 0.79, 95% CI = 0.39-1.61) with high heterogeneity (I 2 = 77%, P = 0.002). After stratifying by region, high NSP coverage in Europe was associated with a 56% reduction in HCV acquisition risk (RR = 0.44, 95% CI = 0.24-0.80) with low heterogeneity (I 2 = 12.3%, P = 0.337), but not in North America (RR = 1.58, I 2 = 89.5%, P = Grades of Recommendation Assessment, Development and Evaluation (GRADE) criteria, the evidence on OST and combined OST/NSP is low quality, while NSP is very low. Opioid substitution therapy reduces risk of hepatitis C acquisition and is strengthened in combination with needle and syringe programmes (NSP).

In Japan, methamphetamine (MAP) abuse has been a serious problem for 60 years, and many of MAP abusers have been incarcerated in prisons as a violator of the Stimulant Control Law in Japan. The purpose of the present study is to evaluate effectiveness of the relapse prevention guidance for drug-dependent inmates using a self-teaching workbook for drug-abusing adolescents and group therapy, conducted in the Harima Rehabilitation Program Center, one of the new prisons which the Ministry of Justice founded cooperating private enterprises as a "Private Finance Initiative" project. We provided for 89 male drug-dependent inmates, incarcerated in the Harima Rehabilitation Program Center, with the relapse prevention guidance consisting of a self-teaching workbook and group therapy, and implement pre-and post-evaluations by the Self-efficacy Scale for Drug Dependence (SES) and the Stages of Change Readiness and Treatment Eagerness Scale, 8th version for Drug Dependence (SOCRATES-8D). After a waiting term, the participants were provided with a self-teaching program, subsequently with a group program. At the point of completing the waiting term, no significant changes were observed in the SES and SOCRATES-8D scores. However, at the point of completing the self-teaching program, the SES scores significantly fell, while the total SOCRATES-8D score and the scores of the two subscales, the "Recognition" and "Ambivalence," significantly rose. Further, at the point of completing the group program, the total scores of the SES and SOCRATES-8D, and the score of the two SOCRATES-8D subscales, the "Recognition" and "Taking Steps," significantly rose. The relapse prevention guidance consisting of a self-teaching workbook and group therapy, conducted in the Harima Rehabilitation Program Center, were supposed to bring same internal changes as the "Stage of Changes" model, proposed by Prochaska and DiClemente, to drug-dependent inmates.

: Antithrombotic therapy is a key component of any strategy for the secondary prevention of ischemic stroke. A better understanding of the various therapeutic options will lead to improved stroke prevention, better medication adherence, and fewer complications. : Antiplatelet agents and anticoagulants are the two major classes of antithrombotic therapy used for stroke prevention. The etiology and mechanism of the stroke must be considered in order to make the best decision regarding which agent(s) to use for secondary stroke prevention. The recent Prevention Regimen for Effectively Avoiding Second Strokes (PRoFESS) study showed that clopidogrel and aspirin plus extended-release dipyridamole had similar event rates in terms of recurrent stroke, but clopidogrel was better tolerated, with fewer bleeding events. Several new anticoagulants are poised to replace warfarin for stroke prevention in the setting of atrial fibrillation. These include dabigatran (a new oral direct thrombin inhibitor) and possibly apixaban (a new oral factor Xa inhibitor). These new medications are much easier to use than warfarin and may be more effective and safer, with fewer drug and food interactions and no need for routine blood monitoring. Thus, these new medications may improve adherence as well as clinicians' inclination to treat with anticoagulation. : Because each antiplatelet agent or anticoagulant has certain advantages and disadvantages, clinicians must choose an agent that the patient can afford and tolerate in terms of side effects and adherence. The hope and expectation is that the proper use of these medications in accordance with current guidelines will reduce the risk of a recurrent stroke.
The most important adverse drug-drug interactions occur with drugs that have seri- ous toxicity and a low therapeutic index, where relatively small changes in drug level can have significant adverse consequences. Additionally, drug-drug interac- tions can be clinically important if the disease being controlled with the drug is.

In India, parent to child transmission is the most important source of HIV infection in children below fifteen years of age. Transmission of HIV from mother to child can occur even at low or undetectable HIV virus levels. CD4 count or HIV RNA levels should not be the determining factor when deciding whether to use antiretroviral drugs for prevention of perinatal transmission of HIV. Use of single dose nevirapine during labour, in prevention of parent to child transmission (PPTCT) programme for pregnant females with CD4 count > 250 cells/cumm has less efficacy in reducing perinatal transmission. And there are high chances of development of nevirapine resistance to both mother and baby after single dose nevirapine exposure. Short course Protease inhibitor(PI) based triple drug combination ART from 28 weeks till delivery for perinatal prophylaxis is effective in reducing perinatal HIV transmission. PI's are safe in pregnancy and also have less chances of development of resistance when used for perinatal prophylaxis and stopped post delivery.Hence, it is opined that PI based combination ART should be offered to pregnant females in PPTCT programme, thereby preventing occurrence of paediatric HIV infection in India. This can have significant impact on the society at large.

The objective of this paper is to review the current status of drug use and HIV/AIDS prevention for drug users in China and provide scientific evidence for HIV/AIDS prevention and control in drug users. Literature and articles related to drug abuse in China, as well as the results of prevention efforts and successful cases regarding HIV/AIDS prevention in drug users, are reviewed. Lessons learned are drawn out for the future improvement of work and the sustainable development of treatment programs. The number of drug users in China is increasing. Even though the number of opioid-type drug users is growing more slowly than in the past, the number of amphetamine-type stimulant users has increased sharply. It has been proven that methadone maintenance treatment and syringe exchange programs gradually and successfully control HIV/AIDS transmission in drug users. However, it is necessary to enhance these prevention methods and expand their coverage. In addition, the strengthening of antiretroviral therapy (ART) treatment for HIV-infected drug users is crucial for HIV/AIDS prevention and control. The rapidly growing number of amphetamine-type stimulant users, along with their high-risk behavior, poses a hidden danger of greater HIV/AIDS transmission through sexual intercourse in the near future.

The prevention of drug use is one of the primary goals of the War on Drugs. However, despite investment in high-profile interventions such as social marketing campaigns and enforcement-based deterrence, these efforts have generally failed. With the emergence of novel policy frameworks to control and regulate drug use, a window of opportunity exists to test approaches to drug prevention that take into account existing evidence and the rights of individuals who use drugs. Specifically, there is a growing consensus that entry into drug use is a socially-defined event that individuals experience within particular socio-structural contexts. This understanding, coupled with a distinction between the value of preventing problematic drug use rather than all drug use, provides a useful framework within which to develop effective and rights-based approaches to drug prevention.

An optimal drug input may be defined as producing an ideal therapeutic effect as closely as possible without exceeding predetermined safety limits on any adverse drug effects. The intensity and time patterns of the drug-elicited response are functions of the pharmacodynamic properties of the drug in the patient. Drug input optimisation can be considered as a control problem and the different control engineering techniques may serve to assist in planning/implementing drug dosage regimens. This paper reviews some problems associated with planning optimal drug therapy in different clinical context and illustrates the solution of such problems by clinical examples.

There has been no relapse prevention program for drug dependent inmates in Japanese prisons. Recently, "Relapse Prevention Guidance" program is provided to the adult male inmates in Harima Rehabilitation Program Center (HRPC), one of the newly founded "Private Finance Initiative" prisons. To evaluate the effectiveness of the program by comparing the outcomes between groups of inmates with different severity level of dependence. The program was provided to 89 subjects in HRPC. Inmates were classified into 4 groups according to the severity measured by the Drug Abuse Screening Test (DAST). After a month of waiting period, self-teaching workbook was provided to each inmate for 4 weeks. The educational program consisting of 8 weekly psychoeducational group therapies was then provided to each group of 10 inmates. The evaluation was conducted both at the beginning and at the end of the workbook and the educational program intervention by administering 2 self-reporting questionnaires; the Self-efficacy Scale for drug dependence (SES), and the 8th version of the Stages of Change Readiness and Treatment Eagerness Scale for drug dependence (SOCRATES-8D). Only the "mild" group showed significant increase in SES during waiting period. After the workbook intervention, "moderate" group showed significant decrease in SES, and increase in the recognition and the ambivalence subscale of the SOCRATES-8D. The same increase in the subscales of SOCRATES-8D was noted in "Severe" group. Educational program produced increase in the recognition and the taking steps subscales of SOCRATES-8D in "mild" group, increase in SES score and the taking steps subscale in "moderate", increase in SES score and total score of SOCRATES-8D in "severe" group. No significant change was noted in "very severe" group in any of the interventions. The "Relapse Prevention Guidance" is sufficiently effective, improving self-efficacy and motivation for change in drug dependent adult male inmates.

Children suffer a huge burden of disease in tuberculosis (TB) endemic countries. This disease burden was largely invisible when TB control programmes focused exclusively on adults with sputum smear-positive disease. High-level advocacy and better data have improved visibility, but the establishment of functional paediatric TB programmes remains challenging. The key issues that limit children's access to TB preventive therapy and treatment in endemic areas are briefly discussed. Barriers to preventive therapy include (1) the perceived inability to rule out active disease, (2) fear of creating drug resistance, (3) non-implementation of existing guidelines in the absence of adequate monitoring, and (4) poor adherence with long preventive therapy courses. Barriers to TB treatment include (1) perceived diagnostic difficulties, (2) non-availability of chest radiography, (3) young children presenting to unprepared maternal and child health (MCH) services, and (4) the absence of child-friendly formulations. With drug-resistant disease there is currently no guidance on the use of preventive therapy and treatment is usually restricted to cases with bacteriologically confirmed disease, which excludes most young children from care, even if their likely source case has documented drug-resistant TB.

A peer counseling program was developed as a method for preventing drug and alcohol abuse among high school juniors and seniors. The program was implemented and the results were monitored to evaluate the impact of the program on the students. An analysis of the data showed that the students were able to learn and utilize peer counseling skills but that the prevention of drug abuse could not be documented in this study. Subjective reports, however, were found to support the effects of the program.

Nanotechnological innovations over the last 16 years have brought about the potential to revolutionize specific therapeutic drug delivery to cancer tissue without affecting normal tissues. In addition, there are new nanotechnology-based platforms for diagnosis of cancers and for theranostics, i.e., integrating diagnosis with therapy and follow-up of effectiveness of therapy. This chapter presents an overview of these nanotechnology-based advancements in the areas of prevention, diagnosis, therapy, and theranostics for cancer. In addition, we stress the need to educate bio- and medical students in the field of nanotechnology.

Pain is one of the most common reasons for consulting a physician. Chronic pain patients often suffer from a variety of comorbidities, such as depression and anxiety and they are therefore often simultaneously treated with more than one drug. The probability of drug interactions increases with every additional drug. A systematic internet and literature search up to February 2015 was carried out. Systematic lists were included. In addition, the drug prescription information sheets were used and an internet search via Pubmed and google.com was carried out for drugs alone and in combination in order to find substance-specific interactions. A differentiation is made between pharmaceutical, pharmacodynamic and pharmacokinetic drug interactions. Pharmaceutical interactions are caused by chemical, physical or physicochemical incompatibility of drugs or adjuvants used. These can even occur outside the body and during concomitant administration via the same route. A pharmacodynamic interaction in pain management is for example the additive sedative effect of opioids and benzodiazepines when taken together. Pharmacokinetic interactions occur during the absorption, distribution, metabolism and in the elimination phases. Many drug interactions can be avoided by careful and continuous evaluation of pharmacotherapy and if necessary its adaptation; however, a sound knowledge of the underlying pharmacological mechanisms and the properties of currently used analgesics is necessary.

Therapeutic options for many infections are extremely limited and at crisis point. We run the risk of entering a second pre-antibiotic era. There had been no miracle drug for the patients infected by resistant microbial pathogens. Most of the very few new drugs under development have problems with their toxicity, or pharmacokinetics and pharmacodynamics. We are already decades behind in the discovery, characterization and development of new antimicrobials. In that scenario, we could not imagine surviving without newer and effective antimicrobial agents. Bacteria have been the champions of evolution and are still evolving continuously, where they pose serious challenges for humans. Along with the crisis of evolving resistance, the condition is made worst by the meager drug pipeline for new antimicrobials. Despite ongoing efforts only 2 new antibiotics (Telavancin in 2009 and Ceftaroline fosamil in 2010) have been approved since 2009 pipeline status report of Infectious Disease Society of America (IDSA). Recent approval of new combination based antiviral drugs such as Stribild (combination of four drugs for HIV treatment) and Menhibrix (combination vaccine to prevent meningococcal disease and Haemophilus influenzae type b in children) proves that combination therapy is still the most promising approach to combat the ever evolving pathogens. Combination therapy involves the drug repurposing and regrouping of the existing antimicrobial agents to provide a synergistic approach for management of infectious diseases. This review article is an effort to highlight the challenges in new drug development and potential of combination drug therapy to deal with them.
This paper describes the review of radiation therapy, neutron capture therapy (NCT) and drug delivery system for the latter. In cancer radiation therapy, there are problems of body movement like breathing, needless irradiation of normal tissues, difficulty to decide the correct irradiation position and tumor morphology. NCT has advantages to overcome these, and since boron has a big cross section for thermal neutron, NPT uses the reaction 10 B(n, α) 7 Li in the target cancer which previously incorporated the boron-containing drug. During the period 1966-1996, 246 patients were treated with this in Japan and the treatment has been continued thereafter. The tasks for NCT are developments of drug delivery system efficient to deliver the drug into the tumor and of convenient neutron source like the accelerator. (S.I.)
Prevention of adverse drug events that may result from medication errors is challenging. The safety of medication treatment is mostly determined on an average population and medication errors may be prevented when pharmacotherapy is better tailored to the individualized needs of the hospitalized

Obesity is a worldwide health problem whose prevalence is on the increase. Many obesity-associated diseases require intensive medical treatment and are the cause of a large proportion of health-related expenditures in Germany. Treatment of obesity includes nutritional, exercise and behaviour therapy, usually in combination. The goal of behaviour therapy for obesity is to bring about a long-term alteration in the eating and exercise habits of overweight and obese individuals. Under certain circumstances, drug treatment may be indicated. What is the effectiveness of behaviour therapy for obesity considering approved drugs reduce weight under medical, economic, ethical-social and legal aspects? A systematic review was conducted using relevant electronic literature databases. Publications chosen according to predefined criteria are evaluated by approved methodical standards of the evidence-based medicine systematically and qualitatively. In total 18 studies, included one HTA and one meta-analysis could be identified according to the predefined inclusion criteria. Three studies compare behaviour therapy to other therapy forms (advice or instruction on nutritional changes, physical activity or a combination of the two), six studies evaluate different forms of behaviour therapy, four studies and four studies compare behaviour therapies mediated by Internet or telephone. Three studies could be identified examining the effect of the combination of behaviour and drug therapy. Furthermore one HTA and one meta-analysis could be included in the evaluation. The behaviour therapy in comparison with other therapy forms reveals a higher effectiveness. In comparison of the different therapeutic approaches of the behaviour therapy intensive behaviour therapy forms and group therapy show a higher effectiveness.

Development of resistance to antiretroviral drugs (ARVs) is a major impediment to optimum treatment of HIV-1 infection. Although resistance testing can help to select subsequent regimens when virologic failure occurs, cross-resistance, which affects all classes of ARVs, may make it more difficult to achieve optimum control of HIV. We have known for some time that our first choice of antiretroviral therapy offers the best chance to control HIV replication and that initial therapy should be selected with an eye on future options. Potency is the first line of defense against the development of resistance. Other factors that affect resistance development include: tolerability, potential for optimum adherence, and genetic and pharmacologic barriers to development of resistance. If resistance emerges, only a single drug may be affected initially, and a rapid change in ARVs may preserve the efficacy of other components. One cautionary note is that we can no longer assume that a patient's HIV is fully susceptible to all ARVs even in the initial regimen. Transmission of drug-resistant HIV means that the genetic composition may be that of an "experienced" virus with reduced susceptibility to ARVs. Resistance testing at the time of transmission is most likely to reveal this resistance, but over time the dominant genetic pattern may revert to wild-type, and be missed by resistance testing. Because "archived" resistant HIV may emerge quickly once treatment is initiated, we need to keep this in mind when selecting initial therapy.

Currently, the development of medicines for complex diseases requires the development of combination drug therapies. It is necessary because in many cases, one drug cannot target all necessary points of intervention. For example, in cancer therapy, a physician often meets a patient having a genomic profile including more than five molecular aberrations. Drug combination therapy has been an area of interest for a while, for example the classical work of Loewe devoted to the synergism of drugs was published in 1928-and it is still used in calculations for optimal drug combinations. More recently, over the past several years, there has been an explosion in the available information related to the properties of drugs and the biomedical parameters of patients. For the drugs, hundreds of 2D and 3D molecular descriptors for medicines are now available, while for patients, large data sets related to genetic/proteomic and metabolomics profiles of the patients are now available, as well as the more traditional data relating to the histology, history of treatments, pretreatment state of the organism, etc. Moreover, during disease progression, the genetic profile can change. Thus, the ability to optimize drug combinations for each patient is rapidly moving beyond the comprehension and capabilities of an individual physician. This is the reason, that biomedical informatics methods have been developed and one of the more promising directions in this field is the application of artificial intelligence (AI). In this review, we discuss several AI methods that have been successfully implemented in several instances of combination drug therapy from HIV, hypertension, infectious diseases to cancer. The data clearly show that the combination of rule-based expert systems with machine learning algorithms may be promising direction in this field. © The Author(s) 2018.

Magnesium is the fourth most abundant mineral in the body. It has been recognized as a cofactor for more than 300 enzymatic reactions, where it is crucial for adenosine triphosphate (ATP) metabolism. Magnesium is required for DNA and RNA synthesis, reproduction, and protein synthesis. Moreover, magnesium is essential for the regulation of muscular contraction, blood pressure, insulin metabolism, cardiac excitability, vasomotor tone, nerve transmission and neuromuscular conduction. Imbalances in magnesium status—primarily hypomagnesemia as it is seen more common than hypermagnesemia—might result in unwanted neuromuscular, cardiac or nervous disorders. Based on magnesium’s many functions within the human body, it plays an important role in prevention and treatment of many diseases. Low levels of magnesium have been associated with a number of chronic diseases, such as Alzheimer’s disease, insulin resistance and type-2 diabetes mellitus, hypertension, cardiovascular disease (e.g., stroke), migraine headaches, and attention deficit hyperactivity disorder (ADHD).

In 2014, Oregon, Alaska, and the District of Columbia joined Colorado and Washington as voters approved initiatives to legally regulate and tax marijuana for adults. Other states, including California, are likely to follow in 2016. While none of these new laws allow sales to minors, there is widespread concern about the potential impact of these reforms on teenagers. Many worry that legalization will "send the wrong message," and increase access and availability, leading to an escalation in teenage use. This new social, political and cultural context presents a new challenge, as marijuana gradually becomes a normal part of the adult world, akin to alcohol. The movement toward legalization provides an opportunity to re-think our approach to teen drug education/prevention. This is the moment to examine current approaches, and devise innovative, pragmatic strategies for dealing with teens and marijuana (and other drug use). As we examine the issue of drug education/prevention in the context of legalization, we detail efforts that have been tried, and what is realistically possible to accomplish, with the health and safety of teenagers our highest priority. A reality-based approach advocates honest, science-based information; encourages moderation, if experimentation persists; promotes an understanding of the legal consequences and social context of drug use; emphasizes safety through personal responsibility and knowledge; and encourages the delay of experimentation with all intoxicating substances until adulthood.

Low-dose lansoprazole has not been intensively evaluated for its efficacy in the prevention of recurrent gastric or duodenal ulcers in patients receiving long-term non-steroidal anti-inflammatory drug (NSAID) therapy for pain relief in such diseases as rheumatoid arthritis, osteoarthritis, and low back pain. This multi-center, prospective, double-blind, randomized, active-controlled study involving 99 sites in Japan was designed to compare the efficacy of lansoprazole (15 mg daily) with gefarnate (50 mg twice daily). Patients with a history of gastric or duodenal ulcers who required long-term NSAID therapy were randomized to receive lansoprazole 15 mg daily (n = 185) or gefarnate 50 mg twice daily (n = 181) and followed up for 12 months or longer prospectively. The cumulative incidence of gastric or duodenal ulcer at days 91, 181, and 361 from the start of the study was calculated by the Kaplan-Meier method as 3.3, 5.9, and 12.7%, respectively, in the lansoprazole group versus 18.7, 28.5, and 36.9%, respectively, in the gefarnate group. The risk for ulcer development was significantly (log-rank test, P lansoprazole group than in the gefarnate group, with the hazard ratio being 0.2510 (95% CI 0.1400-0.4499). A long-term follow-up study showed an acceptable safety profile for low-dose lansoprazole therapy, with diarrhea as the most frequent adverse event. Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term NSAID therapy.
Full Text Available Background: The behavior and dietary treatments are not so successful for extremely obese adolescents. Therefore, using drugs to treat extremely obese children and adolescents are among the modern approaches. This research aims to study the pharmaceutical interventions performed for treatment of obese children. Materials and Methods: The strategy of research was using of key words ‘obesity’, ‘adolescence’, ‘treatment’ and ‘anti-obesity drugs’ were searched in websites of PubMed, Iranian Medical Digital Library, SID, Iran Medex, Magiran. This study reviewed all the available published papers in English and Farsi languages during 2000-2010. The Criteria for exclusion was The papers that had been published on interventions and treatment of eating disorders, type II diabetes or the obesity caused by the secondary syndromes. Results: Twelve papers were found as short-term clinical trials and/or long-term follow-ups. In these studies, the positive effects of ‘sibutramine’ in some studies are shown; although some other side effects are reported as well. A significant weight-loss had been reported on ‘orlistat’ medicine, but digestive complications had been observed as well. None of the studies had followed up patients for more than one year. Apparently, ‘Metformin’ requires further studies.Conclusion: The FDA has only approved ‘sibutramine’ and ‘orlistat’ drugs. But side effects of long-term these drugs have already been unknown. However, it seems that ‘orlistat’ is applied for ≥12-year-old children and ‘sibutramine’ for ≥ 16-year-old children.

Even though the field of medicine has developed tremendously, the wide variety of cancer is still among chronic and life threatening disease today. Therefore, the specialists constantly research and try every possible way to find cure or preventive ways to stop its further development. For this reason, studies concerning the chronic disease such as cancer have been spread to many different fields. In this regard, many other alternative ways besides medicine, are used in prevention of cancer. Nutritional therapy, herbal therapy, sportive activities, art therapy, music therapy, dance therapy, imagery, yoga and acupuncture can be given as examples. Among these, dance/movement therapy which deals with individuals physical, emotional, cognitive as well as social integration is widely used as a popular form of physical activity. The physical benefits of dance therapy as exercise are well documented. Studies have shown that physical activity is known to increase special neurotransmitter substances in the brain (endorphins), which create a state of well-being. And total body movement such as dance enhances the functions of other body systems, such as circulatory, respiratory, skeletal, and muscular systems. Regarding its unique connection to the field of medicine, many researches have been undertaken on the effects of dance/movement therapy in special settings with physical problems such as amputations, traumatic brain injury, and stroke, chronic illnesses such as anorexia, bulimia, cancer, Alzheimer's disease, cystic fibrosis, heart disease, diabetes, asthma, AIDS, and arthritis. Today dance/movement therapy is a well recognized form of complementary therapy used in hospitals as well as at the comprehensive clinical cancer centres.

Medication nonadherence is a major public health problem, especially for patients with coronary artery disease. The cost of prescription drugs is a central reason for nonadherence, even for patients with drug insurance. Removing patient out-of-pocket drug costs may increase adherence, improve clinical outcomes, and even reduce overall health costs for high-risk patients. The existing data are inadequate to assess whether this strategy is effective. The Post-Myocardial Infarction Free Rx and Economic Evaluation (Post-MI FREEE) trial aims to evaluate the effect of providing full prescription drug coverage (ie, no copays, coinsurance, or deductibles) for statins, beta-blockers, angiotensin-converting enzyme inhibitors, and angiotensin II receptor blockers to patients after being recently discharged from the hospital. Potentially eligible patients will be those individuals who receive their health and pharmacy benefits through Aetna, Inc. Patients enrolled in a Health Savings Account plan, who are > or =65 years of age, whose plan sponsor (ie, the employer, union, government, or association that sponsors the particular benefits package) has opted out of participating in the study, and who do not receive both medical services and pharmacy coverage through Aetna will be excluded. The plan sponsor of each eligible patient will be block randomized to either full drug coverage or current levels of pharmacy benefit, and all subsequently eligible patients of that same plan sponsor will be assigned to the same benefits group. The primary outcome of the trial is a composite clinical outcome of readmission for acute MI, unstable angina, stroke, congestive heart failure, revascularization, or inhospital cardiovascular death. Secondary outcomes include medication adherence and health care costs. All patients will be followed up for a minimum of 1 year. The Post-MI FREEE trial will be the first randomized study to evaluate the impact of reducing cost-sharing for essential cardiac

Smart nanocarriers have been designed for tissue-specific targeted drug delivery, sustained or triggered drug release and co-delivery of synergistic drug combinations to develop safer and more efficient therapeutics. Advances in drug delivery systems provide reduced side effects, longer circulation half-life and improved pharmacokinetics. Smart drug delivery systems have been achieved successfully in the case of cancer. These nanocarriers can serve as an intelligent system by considering the differences of tumor microenvironment from healthy tissue, such as low pH, low oxygen level, or high enzymatic activity of matrix metalloproteinases. The performance of anti-cancer agents used in cancer diagnosis and therapy is improved by enhanced cellular internalization of smart nanocarriers and controlled drug release. Here, we review targeting, cellular internalization; controlled drug release and toxicity of smart drug delivery systems. We are also emphasizing the stimulus responsive controlled drug release from smart nanocarriers. Copyright© Bentham Science Publishers; For any queries, please email at email@example.com.

Since publication of the initial ACCP position statement on CDTM by pharmacists in 1997, the public, government, and much of the health care community at large have come to better appreciate the growing complexity of providing effective and safe drug therapy in today's health care environment. Increased interest in the issues of cost and quality of drug use is evident in the increasing coverage of the issue in the lay press and professional literature. This represents real progress, as well as real opportunity, for pharmacists. It also heightens the potential for a better understanding of the vital role that pharmacists can play in addressing these concerns. The percentage of patients who take several drugs for chronic diseases will continue to increase. Based on current trends, the number of patients who lack adequate access to care, or who receive either suboptimal, inappropriate, or unnecessarily expensive drug therapy for their acute and chronic diseases, will increase. Even as financial and human resources are increasingly strained within the current health care system, costs will continue to rise unless changes are made. Fortunately, qualified pharmacists are prepared, capable, and willing to help address a significant portion of these challenges. The public, many health care providers, some legislators, and a few insurers now recognize that pharmacists, because of their education and training in drug therapy, are well positioned both to accept additional responsibility for patient care and to provide services that make a real difference in health care quality and outcomes. The health care programs administered by the U.S. Public Health Service, the armed forces, and the Veterans Health Administration, as well as 38 states, now support pharmacist participation in CDTM. Pharmacists, working in an interdisciplinary structure with physicians and other health care providers, have demonstrated that they can improve the effectiveness, efficiency, and safety of drug

Endothelial-to-mesenchymal transition (EndMT) contributes to the emergence of fibroblasts and plays a significant role in renal interstitial fibrosis. Protein phosphatase 2A (PP2A) is a major serine/threonine protein phosphatase in eukaryotic cells and regulates many signaling pathways. However, the significance of PP2A in EndMT is poorly understood. In present study, the role of PP2A in EndMT was evaluated. We demonstrated that PP2A activated in endothelial cells (EC) during their EndMT phenotype acquisition and in the mouse model of obstructive nephropathy (i.e., UUO). Inhibition of PP2A activity by its specific inhibitor prevented EC undergoing EndMT. Importantly, PP2A activation was dependent on tyrosine nitration at 127 in the catalytic subunit of PP2A (PP2Ac). Our renal-protective strategy was to block tyrosine127 nitration to inhibit PP2A activation by using a mimic peptide derived from PP2Ac conjugating a cell penetrating peptide (CPP: TAT), termed TAT-Y127WT. Pretreatment withTAT-Y127WT was able to prevent TGF-β1-induced EndMT. Administration of the peptide to UUO mice significantly ameliorated renal EndMT level, with preserved density of peritubular capillaries and reduction in extracellular matrix deposition. Taken together, these results suggest that inhibiting PP2Ac nitration using a mimic peptide is a potential preventive strategy for EndMT in renal fibrosis.
WHO reports 36.7 million people are living with Human Immunodeficiency Virus (HIV) worldwide by 2016 with about 1.8 million new infections each year. It will be a specific health problem for the world in both developed and developing countries so it is necessary strategies to reduce HIV transmission to the community. HIV transmission in people with risk factors is largely determined by the amount of virus in the blood of people who are the source of infection. Antiretroviral (ARV) therapy has long been used in HIV patients, which serves to suppress viral replication so that the patient’s immunity increases; opportunistic infections are resolved and prolong the lifespan and lower transmission rates. In the HIV Prevention Trials Network (HPTN) study 052 there was a 96% reduction in transmission in earlier antiretroviral. ARV is also used in the prevention of transmission in people exposed to HIV virus that is Postexposure Prophylaxis as well as in people at risk before exposure (Pre-exposure Prophylaxis). Three prevention strategies with the provision of ARV is expected to be guided as a means of prevention of transmission in addition to behavioral changes has long been declared since the beginning of the HIV epidemic.
Full Text Available ABSTRACT Pharmacodynamical studies showed that most drugs elicit their effects by acting on 3 kinds of protein molecules known as receptors, enzymes or transporters. Although their detail properties had not been explained for decades the roles of transporters in drug kinetics and dynamics has been well understood, even have been applied in the therapy. Transporters are classified into 2 major classes, the solute carriers (SLC and ATP-binding cassette (ABC families. SLC transporters do not possess ATP binding site property as those of ABC transporters. SLC transporters consist of 3 SLC subfamilies i.e. organic cation transporters (OCTs, organic anion transporters (OATs and organic anion transporting polypeptides (OATPs. In contrast, ABC transporters require ATP hydrolysis to transport substrate across cell membrane. Human ABC-transporters consist of ABCA1- 13, ABCB1-11, ABCC1-12, ABCD1-4, ABCE1, ABCF1-3 and ABCG1-8 subfamily. Although the originally funtion of transporter is to transport specific physiological substrate such as nutrient, hormone, cytokines, neurotransmitters and other physiological subtances across cell membrane the specificity is not restricted to each substrate. Drugs and other xenobiotics which have structural similarity to the physiological substrates are recognized and transported by the related transporters. The competition of them on transporters therefore may lead to the occurence of drug-drug interactions (DDI or drugphysiological substrate interaction in the drug-kinetics phase. Many transporters located in the liver, intestinal and renal epithelial cell membranes involve in the transport of endogenous substance or xenobiotics including drugs play important roles as protective barrier. Since transporters also serve as the targets of drug action it is understood that transporters play important role in the pathogenesis of diseases as well as in the drug therapy of diseases.

The delivery of mechanical signals to the skeleton using vibration is being considered as a non-drug treatment of osteoporosis. Delivered over a range of magnitudes and frequencies, vibration has been shown to be both anabolic and anti-catabolic to the musculoskeletal tissues, yet caution must be emphasized as these mechanical signals, particularly chronic exposure to higher intensities, is a known pathogen to many physiological systems. In contrast, accumulating preclinical and clinical evidence indicates that low intensity vibration (LIV) improves bone quality through regulating the activity of cells responsible for bone remodeling, as well as biasing the differentiation fate of their mesenchymal and hematopoietic stem cell progenitors. In vitro studies provide insights into the biologic mechanisms of LIV, and indicate that cells respond to these low magnitude signals through a distinct mechanism driven not by matrix strain but acceleration. These cell, animal, and human studies may represent the foundation of a safe, non-drug means to protect and improve the musculoskeletal system of the elderly, injured, and infirmed.

Pro AED: The central issue in medical decision-making is risk-benefit assessment. Surgery of any type is still considered to be a major undertaking. To warrant these risks, the patient has a right to expect that they have a greater chance of a good outcome with an invasive therapy than with a non-invasive one. The main question is when, if ever, this becomes the case when comparing implantation of a VNS Therapy System versus adding an antiepileptic drug (AED)? After the first drug? The second? After all AEDs have failed? To date, no randomized trial comparing the addition of an AED against vagus nerve stimulation (VNS Therapy) has been undertaken, although several are currently being contemplated. Without this information, it is more difficult to make a case for early implementation of VNS Therapy. Unfortunately, few data are available regarding the potential for patients to become seizure-free after implantation of a VNS Therapy System. Another issue is side effects. It is important to remember that VNS Therapy also produces adverse events, albeit very different in character than those associated with AEDs, to which physicians have become accustomed. These include cough, dyspnea, pharyngitis, voice alteration and sleep apnea. A less frequently discussed, potentially negative consequence of VNS Therapy relates to the ability to obtain imaging of the patient. Patients who have undergone VNS Therapy System implantation are not candidates for imaging of the chest, breast, or abdomen. A second issue is that imaging of the brain can only be performed with MRI scanners that meet certain requirements, and as MRI technology develops, scanners meeting these requirements may become harder to find. However, to summarize, VNS Therapy is an excellent and useful treatment choice. Fortunately, the choice between AEDs and VNS Therapy is not an "either/or" decision. Each has a role in the treatment of patients with epilepsy, and the advantages and disadvantages of each should be
Prevention of cardiovascular disease guided by total risk estimations - challenges and opportunities for practical implementation: highlights of a CardioVascular Clinical Trialists (CVCT) Workshop of the ESC Working Group on CardioVascular Pharmacology and Drug Therapy.
This paper presents a summary of the potential practical and economic barriers to implementation of primary prevention of cardiovascular disease guided by total cardiovascular risk estimations in the general population. It also reviews various possible solutions to overcome these barriers. The report is based on discussion among experts in the area at a special CardioVascular Clinical Trialists workshop organized by the European Society of Cardiology Working Group on Cardiovascular Pharmacology and Drug Therapy that took place in September 2009. It includes a review of the evidence in favour of the \\'treat-to-target\\' paradigm, as well as potential difficulties with this approach, including the multiple pathological processes present in high-risk patients that may not be adequately addressed by this strategy. The risk-guided therapy approach requires careful definitions of cardiovascular risk and consideration of clinical endpoints as well as the differences between trial and \\'real-world\\' populations. Cost-effectiveness presents another issue in scenarios of finite healthcare resources, as does the difficulty of documenting guideline uptake and effectiveness in the primary care setting, where early modification of risk factors may be more beneficial than later attempts to manage established disease. The key to guideline implementation is to improve the quality of risk assessment and demonstrate the association between risk factors, intervention, and reduced event rates. In the future, this may be made possible by means of automated data entry and various other measures. In conclusion, opportunities exist to increase guideline implementation in the primary care setting, with potential benefits for both the general population and healthcare resources.

Leishmania is an obligate intracellular pathogen that invades phagocytic host cells. Approximately 30 different species of Phlebotomine sand flies can transmit this parasite either anthroponotically or zoonotically through their bites. Leishmaniasis affects poor people living around the Mediterranean Basin, East Africa, the Americas, and Southeast Asia. Affected regions are often remote and unstable, with limited resources for treating this disease. Leishmaniasis has been reported as one of the most dangerous neglected tropical diseases, second only to malaria in parasitic causes of death. People can carry some species of Leishmania for long periods without becoming ill, and symptoms depend on the form of the disease. There are many drugs and candidate vaccines available to treat leishmaniasis. For instance, antiparasitic drugs, such as amphotericin B (AmBisome), are a treatment of choice for leishmaniasis depending on the type of the disease. Despite the availability of different treatment approaches to treat leishmaniasis, therapeutic tools are not adequate to eradicate this infection. In the meantime, drug therapy has been limited because of adverse side effects and unsuccessful vaccine preparation. However, it can immediately make infections inactive. According to other studies, vaccination cannot eradicate leishmaniasis. There is no perfect vaccine or suitable drug to eradicate leishmaniasis completely. So far, no vaccine or drug has been provided to induce long-term protection and ensure effective immunity against leishmaniasis. Therefore, it is necessary that intensive research should be performed in drug and vaccine fields to achieve certain results. PMID:29317800

Pressure ulcers affect approximately 10% of patients in hospitals and the elderly are at highest risk. Several studies have suggested that massage therapy may help to prevent the development of pressure ulcers, but these results are inconsistent. To assess the evidence for the effects of massage compared with placebo, standard care or other interventions for prevention of pressure ulcers in at-risk populations.The review sought to answer the following questions:Does massage reduce the incidence of pressure ulcers of any grade?Is massage safe in the short- and long-term? If not, what are the adverse events associated with massage? We searched the Cochrane Wounds Group Specialised Register (8 January 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 1), Ovid MEDLINE (1946 to 8 January 2015), Ovid MEDLINE (In-Process Other Non-Indexed Citations 8 January 2015), Ovid EMBASE (1974 to 8 January 2015), and EBSCO CINAHL (1982 to 8 January 2015). We did not apply date or language restrictions. We planned to include all randomised controlled trials (RCTs) and quasi-randomised controlled trials (Q-RCTs) that evaluated the effects of massage therapy for the prevention of pressure ulcers. Our primary outcome was the proportion of people developing a new pressure ulcer of any grade. Two review authors independently carried out trial selection. Disagreements were resolved by discussion. No studies (RCTs or Q-RCTs) met the inclusion criteria. Therefore, neither a meta-analysis nor a narrative description of studies was possible. There are currently no studies eligible for inclusion in this review. It is, therefore, unclear whether massage therapy can prevent pressure ulcers.

Increasing interest in diverticular disease by the scientific community in the last 10-15 years has resulted in an increased number of publications. Among other things, nonevidence-based therapeutic paradigms were tested in randomized, controlled therapy studies. The importance of surgery in the therapy of diverticulitis has diminished in recent years; in particular, it has no role in the treatment of diverticulitis types 1a, 1b, and 2a according to the Classification of Diverticular Disease (CDD) treated successfully by conservative means. Surgery has only a subordinate role in recurrent type 3b diverticulitis according to the CDD. Diverticulitis is therefore increasingly treated using conservative or drug therapy. However, only the classic, established antibiotics are currently available as effective drugs for the treatment of diverticular disease. However, these are also decreasing in significance. Over 90% of patients with type 1a/1b diverticulitis can be safely treated according to current data without the use of antibiotics. It is possible that type 2a diverticulitis will also be successfully treated without antibiotics in the future. Substances such as rifaximin, mesalazine, or probiotics, which were tested above all in patients with chronic recurrent forms (CDD type 3a/3b), have not yet been established.
Canada has a long tradition of undertaking research and training in pediatric clinical pharmacology, and has one of the longest continuous enterprises in this field in the world. Training in pediatric clinical pharmacology in Canada is nationally accredited and rigorous. Canada has the largest number of pediatric clinical pharmacologists per capita of any country on earth, but to date there have been no federally supported initiatives for child-focused drug research. The recent development of a unique national network focused on drug safety - the Genotypic Approaches to Therapy in Children - has provided a framework that it hopes will facilitate networking as well as the development of coordinated national and hopefully international initiatives in pediatric therapeutics.
Full Text Available Masoud Ghorbani, Ramin Farhoudi Department of Viral Vaccine Production, Pasteur Institute of Iran, Research and Production Complex, Karaj, Iran Abstract: Leishmania is an obligate intracellular pathogen that invades phagocytic host cells. Approximately 30 different species of Phlebotomine sand flies can transmit this parasite either anthroponotically or zoonotically through their bites. Leishmaniasis affects poor people living around the Mediterranean Basin, East Africa, the Americas, and Southeast Asia. Affected regions are often remote and unstable, with limited resources for treating this disease. Leishmaniasis has been reported as one of the most dangerous neglected tropical diseases, second only to malaria in parasitic causes of death. People can carry some species of Leishmania for long periods without becoming ill, and symptoms depend on the form of the disease. There are many drugs and candidate vaccines available to treat leishmaniasis. For instance, antiparasitic drugs, such as amphotericin B (AmBisome, are a treatment of choice for leishmaniasis depending on the type of the disease. Despite the availability of different treatment approaches to treat leishmaniasis, therapeutic tools are not adequate to eradicate this infection. In the meantime, drug therapy has been limited because of adverse side effects and unsuccessful vaccine preparation. However, it can immediately make infections inactive. According to other studies, vaccination cannot eradicate leishmaniasis. There is no perfect vaccine or suitable drug to eradicate leishmaniasis completely. So far, no vaccine or drug has been provided to induce long-term protection and ensure effective immunity against leishmaniasis. Therefore, it is necessary that intensive research should be performed in drug and vaccine fields to achieve certain results. Keywords: leishmania, leishmania treatment, vaccine, recombinant antigens

The problem of drug eluting stents (DES) safety has been actively discussed throughout 2006 because of increase of frequency of development of late stent thromboses which were noted during almost 2 years after stenting. In December 2006 US Food and Drug Administration (FDA) advisory panel acknowledged increase of development of late stent thrombosis. At the same time FDA accepted new definition of stent-thrombosis suggested by the Academic Research Consortium. According to this definition thrombosis can be definite, probable and possible. Any unexplained death before end of follow-up in a trial should be considered thrombosis related. Recalculation of thrombosis rate using this definition caused pronounced increase of this parameter in previously conducted trials. Thrombosis rate rose from 0,6 to 3,3% for bare metal stents, from 0,8 to 3,6% for sirolimus eluting stents and from 1,3 to 3,5% for paclitaxel eluting stents. Professional cardiological and angiographical societies (ACC, AHA, SCAI) responding to FDA advisory panel published their proofs and vision of the problem of stent thrombosis. In February 2007 ACC, AHA, SCAI, American College of Surgeons and Association of Dentists published scientific bulletin in which described preventive measures aimed at lowering of risk of thrombosis development. This document contains strict recommendation to continue double antithrombotic therapy with aspirin and clopidogrel for 12 months after implantation of DES or abandonment of the use of this type of stents when long term double antithrombotic therapy is not possible.

In the current era of antiviral drug therapy, combining multiple drugs is a primary approach for improving antiviral effects, reducing the doses of individual drugs, relieving the side effects of strong antiviral drugs, and preventing the emergence of drug-resistant viruses. Although a variety of new drugs have been developed for HIV, HCV and influenza virus, the optimal combinations of multiple drugs are incompletely understood. To optimize the benefits of multi-drugs combinations, we must investigate the interactions between the combined drugs and their target viruses. Mathematical models of viral infection dynamics provide an ideal tool for this purpose. Additionally, whether drug combinations computed by these models are synergistic can be assessed by two prominent drug combination theories, Loewe additivity and Bliss independence. By combining the mathematical modeling of virus dynamics with drug combination theories, we could show the principles by which drug combinations yield a synergistic effect. Here, we describe the theoretical aspects of multi-drugs therapy and discuss their application to antiviral research.

There is an emerging paradigm shift in oncology that seeks to emphasize molecularly targeted approaches for cancer prevention and therapy. Chalcones (1,3-diphenyl-2-propen-1-ones), naturally-occurring compounds with widespread distribution in spices, tea, beer, fruits and vegetables, consist of open-chain flavonoids in which the two aromatic rings are joined by a three-carbon α, β-unsaturated carbonyl system. Due to their structural diversity, relative ease of chemical manipulation and reaction of α, β-unsaturated carbonyl moiety with cysteine residues in proteins, some lead chalcones from both natural products and synthesis have been identified in a variety of screening assays for modulating important pathways or molecular targets in cancers. These pathways and targets that are affected by chalcones include MDM2/p53, tubulin, proteasome, NF-kappa B, TRIAL/death receptors and mitochondria mediated apoptotic pathways, cell cycle, STAT3, AP-1, NRF2, AR, ER, PPAR-γ and β-catenin/Wnt. Compared to current cancer targeted therapeutic drugs, chalcones have the advantages of being inexpensive, easily available and less toxic; the ease of synthesis of chalcones from substituted benzaldehydes and acetophenones also makes them an attractive drug scaffold. Therefore, this review is focused on molecular targets of chalcones and their potential implications in cancer prevention and therapy. PMID:24467530

Full Text Available Irrational drug use is one of the main health problems all over the world, especially in developing countries. Limited studies about irrational drug use examples showed that main defects. These are polypharmacy, use of drug drug incompatible with diagnosis, inappropriate use of antibiotics, unnecessary use of expensive drug and people's self-treatment with over the counter and prescribing drugs. There are many reasons for irrational drug use. The main reasons are lack of education, socio-cultural, economic and resulting from regulatory mechanism factors. These reasons affect each other, so problems become more complicated. Reasons resulting from pharmacist and doctors occurs basic of irrational drug use. So attitude of doctors and pharmacist toward rational drug use should be evaluated for resolve defects, formal and non-formal education should be continually used and improved. Rational drug use policies should be developed involving drug companies, doctors, pharmacists and patients. [Archives Medical Review Journal 2015; 24(4.000: 452-462

Nanotechnology has rapidly expanded into all areas of science; it offers significant alternative ways to solve scientific and medical questions and problems. In dentistry, nanotechnology has been exploited in the development of restorative materials with some significant success. This review discusses nanointerfaces that could compromise the longevity of dental restorations, and how nanotechnolgy has been employed to modify them for providing long-term successful restorations. It also focuses on some challenging areas in dentistry, eg, oral biofilm and cancers, and how nanotechnology overcomes these challenges. The recent advances in nanodentistry and innovations in oral health-related diagnostic, preventive, and therapeutic methods required to maintain and obtain perfect oral health, have been discussed. The recent advances in nanotechnology could hold promise in bringing a paradigm shift in dental field. Although there are numerous complex therapies being developed to treat many diseases, their clinical use requires careful consideration of the expense of synthesis and implementation.

Substance abuse is a common problem among HIV-infected individuals. Importantly, addictions as well as moderate use of alcohol, smoking, or other illicit drugs have been identified as major reasons for non-adherence to antiretroviral therapy (ART) among HIV patients. The literature also suggests a decrease in the response to ART among HIV patients who use these substances, leading to failure to achieve optimal virological response and increased disease progression. This review discusses the challenges with adherence to ART as well as observed drug interactions and known toxicities with major drugs of abuse, such as alcohol, smoking, methamphetamine, cocaine, marijuana, and opioids. The lack of adherence and drug interactions potentially lead to decreased efficacy of ART drugs and increased ART, and drugs of abuse-mediated toxicity. As CYP is the common pathway in metabolizing both ART and drugs of abuse, we discuss the possible involvement of CYP pathways in such drug interactions. We acknowledge that further studies focusing on common metabolic pathways involving CYP and advance research in this area would help to potentially develop novel/alternate interventions and drug dose/regimen adjustments to improve medication outcomes in HIV patients who consume drugs of abuse.

Severe, long-lasting influenza infections are often caused by new strains of influenza. The long duration of these infections leads to an increased opportunity for the emergence of drug resistant mutants. This is particularly problematic for new strains of influenza since there is often no vaccine, so drug treatment is the first line of defense. One strategy for trying to minimize drug resistance is to apply periodic treatment. During treatment the wild-type virus decreases, but resistant virus might increase; when there is no treatment, wild-type virus will hopefully out-compete the resistant virus, driving down the number of resistant virus. We combine a mathematical model of severe influenza with a model of drug resistance to study emergence of drug resistance during a long-lasting infection. We apply periodic treatment with two types of antivirals: neuraminidase inhibitors, which block release of virions; and adamantanes, which block replication of virions. We compare the efficacy of the two drugs in reducing emergence of drug resistant mutants and examine the effect of treatment frequency on the emergence of drug resistant mutants.

Adverse drug events (ADEs) have been highlighted as a national patient safety and public health challenge by the National Action Plan for Adverse Drug Event Prevention (ADE Action Plan), which was released by the Office of Disease Prevention and Health Promotion in August 2014. The following October, the ADE Prevention: 2014 Action Plan Conference provided an opportunity for federal agencies, national experts, and stakeholders to coordinate and collaborate in the initiative to reduce preventable ADEs. The single-day conference included morning plenary sessions focused on the surveillance, evidence-based prevention, incentives and oversights, and additional research needs of the drug classes highlighted in the ADE Action Plan: anticoagulants, diabetes agents, and opioids. Afternoon breakout sessions allowed for facilitated discussions on measures for tracking national progress in ADE prevention and the identification of opportunities to ensure safe and high-quality health care and medication use. © The Author(s) 2015.

Mitosis is a complex process resulting in division of a cell into two daughter cells, and its failure often results in the death of the daughter cells (via apoptotic, necrotic, or proliferative/senescent death). Many chemicals that inhibit the mitotic process (anti-mitotic drugs) have proven effective for killing cancer cells in vitro and in clinical settings. Among the most studied anti-mitotic drugs are plant-origin natural products including taxanes (e.g. paclitaxel, docetaxel) and vinca alkaloids (e.g. vincristine, vinblastine), whose validated target is the spindle microtubules. With the success of these agents, efforts have been made to develop other spindle poisons as well as to improve efficacy of existing spindle poisons with structural modifications. Novel drugs and natural products that inhibit other proteins involved in mitosis (nonmicrotubule targets) have been sought in hopes of expanding available cancer-directed therapies. Recently, significant advances have been made in the understanding of mitotic mechanisms in tumor cells as well as in normal epithelial cells. These advances help us to identify and develop potential natural agents for the prevention and treatment of cancer. This review will focus on natural products that target mitotic process and/or proteins involved in mitotic progression.

Recent advances in cancer molecular biology have resulted in parallel and unprecedented progress in the development of targeted cancer therapy. Targeted therapy can provide higher efficacy and lower toxicity than conventional chemotherapy for cancer. However, like traditional chemotherapy, molecularly targeted cancer therapy also faces the challenge of drug resistance. Multiple mechanisms are responsible for chemotherapy resistance in tumors, including over-expression of efflux transporters, somatic alterations of drug targets, deregulation of apoptosis, and numerous pharmacokinetic issues. Nanotechnology based approaches are proving to be efficacious in overcoming drug resistance in cancer. Combination of targeted therapies with nanotechnology approaches is a promising strategy to overcome targeted therapy drug resistance in cancer treatment. This review discusses the mechanisms of targeted drug resistance in cancer and discusses nanotechnology approaches to circumvent this resistance.
Prescrire's analyses showed that the quality of drug packaging in 2010 still left much to be desired. Potentially dangerous packaging remains a significant problem: unclear labelling is source of medication errors; dosing devices for some psychotropic drugs create a risk of overdose; child-proof caps are often lacking; and too many patient information leaflets are misleading or difficult to understand. Everything that is needed for safe drug packaging is available; it is now up to regulatory agencies and drug companies to act responsibly. In the meantime, health professionals can help their patients by learning to identify the pitfalls of drug packaging and providing safe information to help prevent medication errors.

Cognitive-behavioral therapies have been successfully used to treat addiction. This article is in part a review on addiction models such as relapse prevention by Marlatt & Gordon, stages of change by Prochaska, DiClemente & Norcross, deriving from motivational interview, developed by Miller & Rollnick, as well as the cognitive models by Beck et al. Based on literature evidence for the development of effective treatment programs, we report on a group treatment model used in a group of alcoholics referred by the Department of Worker's Health Surveillance at Universidade Federal do Rio de Janeiro to the Alcoholism Rehabilitation and Research Center. Results are presented indicating that this type of treatment could be one alternative to others treatments in use. New research is needed to better validate cognitive-behavioral approach to alcohol and drug problems.

This article introduces the scope of the Special Issue. A variety of scientific disciplines are brought together to establish theoretical integration of the arenas of drug use, misuse, "abuse," and drug misuse prevention. Transdisciplinary scientific collaboration (TDSC) is utilized as a process of integration. Introductory comments regarding the strengths and limitations of TDSC are presented. Then, the relevance of genetics to substance misuse and substance misuse prevention is presented. Next, the relevance of cognition for prevention is discussed. Specifically, neurologically plausible distinctions in cognition and implicit cognition and their relevance for prevention are discussed. At a relatively molar social-level of analysis, social network theory, systems dynamic models, geographic information systems models, cultural psychology, and political science approaches to drug misuse and its prevention are introduced. The uses of both quantitative and qualitative statistical approaches to prevention are mentioned next. Finally, targeted prevention, bridging the efficacy-effectiveness gap, and a statement on overcoming disbalance round out the Special Issue. The bridges created will serve to propel drug misuse "prevention science" forward in the years to come. Advances in understanding etiological issues, translation to programs, and ecological fit of programming are desired results.
Nonpharmacologic Interventions to Prevent Pressure Ulcers in Older Patients: An Overview of Systematic Reviews (The Software ENgine for the Assessment and optimization of drug and non-drug Therapy in Older peRsons [SENATOR] Definition of Optimal Evidence-Based Non-drug Therapies in Older People [ONTOP] Series).

Pressure ulcers (PUs) are frequent in older patients, and the healing process is usually challenging, therefore, prevention should be the first strategic line in PU management. Nonpharmacologic interventions may play a role in the prevention of PUs in older people, but most systematic reviews (SRs) have not addressed this specific population using convincing outcome measures. To summarize and critically appraise the evidence from SRs of the primary studies on nonpharmacologic interventions to prevent PUs in older patients. SR and meta-analysis of comparative studies. PubMed, Cochrane Database of Systematic Reviews, EMBASE, and CINHAL (from inception to October 2013) were searched. A new search for updates in the Cochrane Database was launched in July 2014. SRs that included at least 1 comparative study evaluating any nonpharmacologic intervention to prevent PUs in older patients, in any healthcare setting, were selected. Any primary study with experimental design was then identified and included. From each primary study, quality assessment was undertaken as specified by the Cochrane Collaboration and the Grading of Recommendations Assessment, Development and Evaluation working group. Interventions were identified and compared among different studies to explore the possibility of performing a meta-analysis, using the incidence of new pressure ulcers as the main outcome measure. One hundred ten SRs with 65 primary studies satisfied the inclusion criteria. The most frequent interventions explored in these trials were support surfaces (41 studies), repositioning (8), and nutrition interventions (5). High quality of evidence was not found for any intervention, mainly because of a high risk of bias and imprecision. There is moderate quality evidence to support the use of alternating pressure support mattresses over usual hospital mattresses in medical and surgical inpatients, low quality evidence to support constant low pressure devices and Australian medical sheepskin

A multicenter retrospective study of the risk factors associated with medication-related osteonecrosis of the jaw after tooth extraction in patients receiving oral bisphosphonate therapy: can primary wound closure and a drug holiday really prevent MRONJ?
Hasegawa, T; Kawakita, A; Ueda, N; Funahara, R; Tachibana, A; Kobayashi, M; Kondou, E; Takeda, D; Kojima, Y; Sato, S; Yanamoto, S; Komatsubara, H; Umeda, M; Kirita, T; Kurita, H; Shibuya, Y; Komori, T
Root amputation, extraction of a single tooth, bone loss or severe tooth mobility, and an unclosed wound were significantly associated with increased risk of developing medication-related osteonecrosis of the jaw (MRONJ). We recommend a minimally traumatic extraction technique, removal of any bone edges, and mucosal wound closure as standard procedures in patients receiving bisphosphonates. Osteonecrosis of the jaws can occur following tooth extraction in patients receiving bisphosphonate drugs. Various strategies for minimizing the risk of MRONJ have been advanced, but no studies have comprehensively analyzed the efficacy of factors such as primary wound closure, demographics, and drug holidays in reducing its incidence. The purpose of this study was to retrospectively investigate the relationships between these various risk factors after tooth extraction in patients receiving oral bisphosphonate therapy. Risk factors for MRONJ after tooth extraction were evaluated using univariate and multivariate analysis. All patients were investigated with regard to demographics; type and duration of oral bisphosphonate use; whether they underwent a discontinuation of oral bisphosphonates before tooth extraction (drug holiday), and the duration of such discontinuation; and whether any additional surgical procedures (e.g., incision, removal of bone edges, root amputation) were performed. We found that root amputation (OR = 6.64), extraction of a single tooth (OR = 3.70), bone loss or severe tooth mobility (OR = 3.60), and an unclosed wound (OR = 2.51) were significantly associated with increased risk of developing MRONJ. We recommend a minimally traumatic extraction technique, removal of any bone edges, and mucosal wound closure as standard procedures in patients receiving bisphosphonates. We find no evidence supporting the efficacy of a pre-extraction short-term drug holiday from oral bisphosphonates in reducing the risk of MRONJ.
Idiosyncratic drug toxicity has led to the market withdrawal of many drugs in the past. Since animal experiments are not predictive of such toxicity, the pharmaceutical industry continues to seek new methodologies for the prevention of such effects. Although the mechanism of idiosyncratic drug toxicity remains unclear, immune reactions are likely involved. Although drugs with low molecular weights are typically not themselves immunogenic, these drugs may become haptens after being converted to chemically reactive metabolites and becoming covalently cross-linked to proteins. Therefore, screening tests to detect chemically reactive metabolites, most typically by trapping with glutathione, are carried out at early stages of drug development. More quantitative methods are used in later stages of drug development; radioassays for covalent binding (using (14)Cor (3)H-labeled compounds) are most frequently employed. A zone classification system created by combining previous assessment criteria for the chemically reactive metabolites in vitro (assessment of drug candidates. A mechanism for idiosyncratic, drug-induced hepatotoxicity is proposed by analogy to virus-induced hepatitis, where cytotoxic T lymphocytes play an important role; we suggest that idiosyncrasy reflects the involvement of polymorphisms in the human leucocyte antigen-encoding loci. In fact, a strong correlation has been found between of idiosyncratic drug toxicity and specific human leucocyte antigen genotypes. Therefore, screening of patients for gene biomarkers is expected to reduce the clinical risk of idiosyncratic drug toxicity, thereby prolonging the life cycle of otherwise useful drugs.
Preventing pressure ulcers is complex and involves skin care, the provision of therapy mattresses, repositioning, the management of incontinence and adequate nutritional support. This article describes a model of therapy mattress provision that is based on non-powered products. Evaluating the efficiency of this model is challenging, due to the complexities of care, but Safety Thermometer data and incidents reports offer reassurance that non-powered therapy mattresses can provide adequate pressure ulcer prevention. Therapy mattress provision is only one of the five interventions and these are described in details to give readers a fuller picture of the model used at the author's trust.

One of today's controversies remains the prevention of recurrent diverticulitis. Current guidelines advise a conservative approach, based on studies showing low recurrence rates and a high operative morbidity and mortality. Conservative measures in prevention recurrence are dietary advises and medical therapies, including probiotics and 5-aminosalicylic acid. The aim of this systematic review is to assess whether medical or dietary therapies can prevent recurrent diverticulitis after a primary episode of acute diverticulitis. METHOD AND SEARCH STRATEGY: We searched different databases for papers published between January 1966 and January 2011. Clinical studies were eligible for inclusion if they assessed the prevention of recurrent diverticulitis with a medical or dietary therapy. Exclusion criteria were studies without a control group. Three randomized controlled trials (RCT), all with a Jadad quality score of 2 out of 5, were included in this systematic review. Mesalazine results in significantly less disease recurrence and fewer symptoms after an acute episode. The use of probiotics decreases symptoms but does not reduce recurrence. No difference in effect is seen when Balsalazide is added to probiotics compared to probiotics only. No relevant studies on dietary therapy/advices or antibiotics for prevention of recurrent diverticulitis were found. The evidence that supports medical therapy to prevent recurrent diverticulitis is of poor quality. Treatment with 5-aminosalicylic acid seems promising. Based on current data, no recommendation of any non-operative relapse prevention therapy for diverticular disease can be made.

Pulmonary diseases and infections are among the top contributors to human morbidity and mortality worldwide, and despite the successful history of vaccines and antimicrobial therapeutics, infectious disease still presents a significant threat to human health. Effective vaccines are frequently unavailable in developing countries, and successful vaccines have yet to be developed for major global maladies, such as tuberculosis. Furthermore, antibiotic resistance poses a growing threat to human health. The “Challenges and Future in Vaccines, Drug Development, and Immunomodulatory Therapy” session of the 2013 Pittsburgh International Lung Conference highlighted several recent and current studies related to treatment and prevention of antibiotic-resistant bacterial infections, highly pathogenic influenza, respiratory syncytial virus, and tuberculosis. Research presented here focused on novel antimicrobial therapies, new vaccines that are either in development or currently in clinical trials, and the potential for immunomodulatory therapies. These studies are making important contributions to the areas of microbiology, virology, and immunology related to pulmonary diseases and infections and are paving the way for improvements in the efficacy of vaccines and antimicrobials.

Various clinical and epidemiologic studies show that nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin and cyclooxygenase inhibitors (COXIBs) help prevent cancer. Since eicosanoid metabolism is the main inhibitory targets of these drugs the resulting molecular and biological impact is generally accepted. As our knowledge base and technology progress we are learning that additional targets may be involved. This review attempts to summarize these new developments in the field.

In addition to their therapeutic effects on malignant cells, cytotoxic agents have the potential of causing destruction of healthy, normal cells. Extravasation of the drug can produce extensive necrosis of the skin and subcutaneous tissue. Management of these extravasational effects differs from one centre to another and prevention is usually strongly emphasized. We analyzed our management of 12 patients referred to us over five years with extravasation of cytotoxic drugs and reviewed the lit...

About one in every three adults are affected by lower limb muscle cramps. For some people, these cramps reduce quality of life, quality of sleep and participation in activities of daily living. Many interventions are available for lower limb cramps, but some are controversial, no treatment guidelines exist, and often people experience no benefit from the interventions prescribed. To assess the effects of non-drug, non-invasive treatments for lower limb cramp. We searched the Cochrane Neuromuscular Disease Group Specialized Register (13 September 2011) using the terms: cramp, spasm, contracture, charley horse and lower limb, lower extremity, foot, calf, leg, thigh, gastrocnemius, hamstring, quadriceps. We also searched CENTRAL (2011, Issue 3), MEDLINE (January 1966 to August 2011) and EMBASE (January 1980 to August 2011) and the reference lists of included studies. There were no language or publication restrictions. All randomised controlled trials of non-drug, non-invasive interventions trialled over at least four weeks for the prevention of lower limb muscle cramps in any group of people. We excluded, for example, surgery, acupuncture and dry-needling, as invasive interventions. We selected only trials that included at least one of the following outcomes: cramp frequency, cramp severity, health-related quality of life, quality of sleep, participation in activities of daily living and adverse outcomes. Two authors independently selected trials, assessed risk of bias and cross checked data extraction and analysis. A third author was to arbitrate in the event of disagreement. We asked the authors of five trials for information to assist with screening studies for eligibility and received four responses. One trial was eligible for inclusion. All participants were age 60 years or over and had received a repeat prescription from their general practitioner of quinine for nighttime cramps in the preceding three months. This review includes data from only those

The biomedical intervention that has had a major impact on the natural history of HIV and on the global HIV epidemic is antiretroviral therapy (ART). However, the emergence of drug-resistant HIV, an inevitable consequence of increasing use of antiretroviral drugs, poses a major threat to ART success. At the turn of this century, access to life-saving ART was accelerated in low and middle-income countries with the Millennium Development Goal of 15 million individuals receiving ART by 2015 expected to be achieved. However, ART access needs to continue to expand to help bring HIV under control by 2030. The standard of care for people living with HIV in resource- limited settings differs dramatically compared to high-income countries, and not unexpectedly, ART rollout in these settings has resulted in an increase in acquired and transmitted drug resistance. Also of concern, the same drug classes used for ART have been approved or are being progressed for HIV prevention and drug resistance could mitigate their effectiveness for treatment and prevention. In the absence of an effective HIV vaccine and cure, it is imperative that the antiretroviral drug pipeline contains new classes of HIV inhibitors that are active against circulating drug-resistant strains. Studies to advance our fundamental understanding of HIV replication needs to continue, including the interplay between virus and host cell factors, to identify and characterize new drug targets for chemotherapeutic intervention.

Adverse drug events (ADE) and medication errors (ME) are common causes of morbidity in patients presenting at emergency departments (ED). Recognition of ADE as being drug related and prevention of ME are key to enhancing pharmacotherapy safety in ED. We assessed the applicability of the Pareto principle (~80 % of effects result from 20 % of causes) to address locally relevant problems of drug therapy. In 752 cases consecutively admitted to the nontraumatic ED of a major regional hospital, ADE, ME, contributing drugs, preventability, and detection rates of ADE by ED staff were investigated. Symptoms, errors, and drugs were sorted by frequency in order to apply the Pareto principle. In total, 242 ADE were observed, and 148 (61.2 %) were assessed as preventable. ADE contributed to 110 inpatient hospitalizations. The ten most frequent symptoms were causally involved in 88 (80.0 %) inpatient hospitalizations. Only 45 (18.6 %) ADE were recognized as drug-related problems until discharge from the ED. A limited set of 33 drugs accounted for 184 (76.0 %) ADE; ME contributed to 57 ADE. Frequency-based listing of ADE, ME, and drugs involved allowed identification of the most relevant problems and development of easily to implement safety measures, such as wall and pocket charts. The Pareto principle provides a method for identifying the locally most relevant ADE, ME, and involved drugs. This permits subsequent development of interventions to increase patient safety in the ED admission process that best suit local needs.

Drug combination therapy, which is considered as an alternative to single drug therapy, can potentially reduce resistance and toxicity, and have synergistic efficacy. As drug combination therapies are widely used in the clinic for hypertension, asthma, and AIDS, they have also been proposed for the treatment of cancer. However, it is difficult to select and experimentally evaluate effective combinations because not only is the number of cancer drug combinations extremely large but also the effectiveness of drug combinations varies depending on the genetic variation of cancer patients. A computational approach that prioritizes the best drug combinations considering the genetic information of a cancer patient is necessary to reduce the search space. We propose an in-silico method for personalized drug combination therapy discovery. We predict the synergy between two drugs and a cell line using genomic information, targets of drugs, and pharmacological information. We calculate and predict the synergy scores of 583 drug combinations for 31 cancer cell lines. For feature dimension reduction, we select the mutations or expression levels of the genes in cancer-related pathways. We also used various machine learning models. Extremely Randomized Trees (ERT), a tree-based ensemble model, achieved the best performance in the synergy score prediction regression task. The correlation coefficient between the synergy scores predicted by ERT and the actual observations is 0.738. To compare with an existing drug combination synergy classification model, we reformulate the problem as a binary classification problem by thresholding the synergy scores. ERT achieved an F1 score of 0.954 when synergy scores of 20 and -20 were used as the threshold, which is 8.7% higher than that obtained by the state-of-the-art baseline model. Moreover, the model correctly predicts the most synergistic combination, from approximately 100 candidate drug combinations, as the top choice for 15 out of the

Diverticular disease is a common problem. Prevention and treatment of complications depend on the stage of the disease. Lifestyle modifications are suitable preventive measures, aiming to reduce obesity and to balance the diet with a high amount of fiber and a low amount of meat. However, evidence to guide the pharmacological treatment of diverticular disease and diverticulitis is limited. Literature review. Antibiotics are not proven to be effective in patients with uncomplicated diverticulitis and without further risk factors; neither do they improve treatment nor prevent complications. Mesalazine might have an effect on pain relief in diverticular disease even though it has no significant effect on the outcome of diverticulitis. In complicated diverticulitis, inpatient treatment including antibiotics is mandatory. Evidence for the treatment of diverticular disease is limited. Further research is needed.

The current study aims to assess the preventability of the contrast media adverse drug reactions reported through the Campania spontaneous reporting system, identifying the possible limitations emerged in this type of evaluation. All the individual case safety reports validated by the Campania Pharmacovigilance Regional Centre from July 2012 to September 2015 were screened to select those that reported contrast media as suspected drug. Campania Preventability Assessment Committee, in collaboration with clinicians specialized in Radiology, assessed the preventability according to the P-Method, through a case-by-case approach. From July 2012 to September 2015, 13798 cases were inserted by pharmacovigilance managers in the Italian Pharmacovigilance Network database (in the geographical contest of the Campania Region), of which 67 reported contrast media as suspected drug. Five preventable cases were found. The most reported causes for preventability were the inappropriate drug use for the case clinical conditions and the absence of the preventive measure administrated prior to the contrast media administration. Several limitations were found in the evaluation of the critical criteria for the preventability assessment. Educational initiatives will be organized directly to the healthcare professionals involved in the contrast media administration, to promote an appropriate use of the contrast media.
Full Text Available Around one third of the world's population may harbour latent tuberculosis infection (LTBI, an asymptomatic immunological state that confers a heightened risk of subsequently developing tuberculosis (TB. Effectively treating LTBI will be essential if the End TB Strategy is to be realized. This review evaluates the evidence in relation to the effectiveness of preventive antibiotic therapy to treat LTBI due to both drug-susceptible and drug-resistant bacteria. Current national and international preventive therapy guidelines are summarized, as well as ongoing randomized trials evaluating regimens to prevent drug-resistant TB. Populations that may benefit most from screening and treatment for LTBI include close contacts of patients with TB (particularly children under 5 years of age and individuals with substantial immunological impairment. The risks and benefits of treatment must be carefully balanced for each individual. Electronic decision support tools offer one way in which clinicians can help patients to make informed decisions. Modelling studies indicate that the expanded use of preventive therapy will be essential to achieving substantial reductions in the global TB burden. However, the widespread scale-up of screening and treatment will require careful consideration of cost-effectiveness, while ensuring the drivers of ongoing disease transmission are also addressed.

Photodynamic therapy (PDT), an established clinical modality for a variety of malignant and non-malignant diseases, inflicts photoreactive drug-mediated oxidative stress that prompts the engagement of host inflammatory and immune responses which contribute to the therapy outcome. Recently, it has become evident that in vitro PDT-treated tumor cells or their lysates can be utilized as an effective vaccine against established tumors of the same origin. The mechanism underlying the vaccine action appears to be based on eliciting immune recognition of the tumor and developing an efficient immune response even against poorly immunogenic tumors. This study examined whether PDT-generated vaccines can be effectively combined with radiotherapy. Subcutaneous SCCVII tumors (squamous cell carcinomas) growing in syngeneic C3H/HeN mice were treated by radiotherapy (60 Gy x-ray dose). PDT-vaccine treatment, done by peritumoral injection of in vitro PDT-treated SCCVII cells (20 million/mouse), was performed either immediately after radiotherapy or ten days later. The mice were then observed for tumor regression/recurrence. The tumors treated with radiotherapy alone shrunk and became impalpable for a brief period after which they all recurred. In contrast, vaccination performed at 10 days post radiotherapy delayed tumor recurrence and prevented it in one of six mice. Even better results were obtained with mice vaccinated immediately after radiotherapy, with mice showing not only a delayed tumor recurrence but also no sign of tumor in 50% of mice. The PDT-vaccine treatment without radiotherapy produced in this trial a significant tumor growth retardation but no complete regressions. These results indicate that PDT-generated vaccines can ensure immune rejection of cancer once the lesion size is reduced by radiotherapy. Even without obtaining a systemic immunity for the elimination of disseminated malignant deposits, these findings suggest that PDT-vaccines can improve local control

The motive behind present work was to formulate and evaluate gel containing microsponges of diclofenac diethylamine to provide prolonged release for proficient arthritis therapy. Quasi-emulsion solvent diffusion method was implied using Eudragit RS-100 and microsponges with varied drug-polymer ratios were prepared. For the sake of optimization, diverse factors affecting microparticles physical properties were too investigated. Microsponges were characterized by SEM, DSC, FT-IR, XRPD and particle size analysis, and evaluated for morphology, drug loading, in vitro drug release and ex vivo diffusion as well. There were no chemical interactions between drug and polymers used as revealed by compatibility studies outcomes. The drug polymer ratio reflected notable effect on drug content, encapsulation efficiency and particle size. SEM results revealed spherical microsponges with porous surface, and had 7.21 μm mean particle size. The microsponges were then incorporated in gel; which exhibited viscous modulus along with pseudoplastic behavior. In vitro drug release results depicted that microsponges with 1:2 drug-polymer ratio were more efficient to give extended drug release of 75.88% at the end of 8 h; while conventional formulation get exhausted incredibly earlier by releasing 81.11% drug at the end of 4 h only. Thus the formulated microsponge-based gel of diclofenac diethylamine would be a promising alternative to conventional therapy for safer and efficient treatment of arthritis and musculoskeletal disorders.

Magnetic nanoparticles have been investigated for biomedical applications for more than 30 years. In medicine they are used for several approaches such as magnetic cell separation or magnetic resonance imaging (MRI). The development of biocompatible nanosized drug delivery systems for specific targeting of therapeutics is the focus of medical research, especially for the treatment of cancer and diseases of the vascular system. In an experimental cancer model, we performed targeted drug delivery and used magnetic iron oxide nanoparticles, bound to a chemotherapeutic agent, which were attracted to an experimental tumour in rabbits by an external magnetic field (magnetic drug targeting). Complete tumour remission could be achieved. An important advantage of these carriers is the possibility for detecting these nanoparticles after treatment with common imaging techniques (i.e. x-ray-tomography, magnetorelaxometry, magnetic resonance imaging), which can be correlated to histology

Acute diverticulitis of the colon represents a significant burden for national health systems, in terms of direct and indirect costs. Past guidelines claimed that recurrent episodes (two or more) of diverticulitis need surgery, but revised guidelines recommend an individualized approach to patients after an attack of acute diverticulitis. For these reasons, conservative treatment has become the preferred choice after an episode of diverticulitis. Thus, significant efforts are now being focused to identify the correct therapeutic approach to prevent diverticulitis relapses. Nonabsorbable antibiotics, 5-aminosalicylic acid and probiotics are currently being investigated in this way. The effectiveness and the future perspectives of these treatments are discussed herein.

Full Text Available Prevention of gastrointestinal tract (GIT complications is the most important element for the rational use of nonsteroidal anti-inflammatory drugs (NSAIDs and low-dose aspirin (LDA. Proton pump inhibitors (PPIs have long been the only medication to prevent these complications. However, PPIs are only effective in preventing and treating upper GIT diseases (NSAID gastropathy rather than small intestinal injury (NSAID enteropathy. Rebamipide has emerged as a novel agent to protect the gastrointestinal mucosa today. The effect of the drug differs from that of PPIs: it is a typical gastroand enteroprotector that enhances the synthesis of endogenous prostaglandins and possesses a significant anti-inflammatory potential. Rebamipide has long been widely used by doctors inJapan,South Korea, andChinaas an effective and safe agent for the treatment of many diseases of the digestive system. There is a strong evidence base for the efficacy of rebamipide in preventing and treating NSAID gastropathy and NSAID enteropathy (including LDA-induced injuries. Controlled studies have found that the drug is not inferior to the classic gastroprotective agent misoprostol, significantly outperforming the latter in its tolerability. This review describes the mechanism of action of rebamipide and main clinical trials of its therapeutic effect in NSAID gastropathy and NSAID enteropathy.

Travellers' diarrhoea remains a major public health problem, contributing to significant morbidity and disability. Because bacterial enteropathogens cause a majority of this form of diarrhoea, antibacterial drugs are effective when used in chemoprophylaxis or for empirical treatment.A review of the MEDLINE listings for travellers' diarrhoea for the past 4 years was conducted; a library of >1,000 scientific articles on the topic was also considered in developing this review. Persons who travel from industrialised countries to developing countries of the tropical and semi-tropical world are the individuals who experience travellers' diarrhoea. While diarrhoea occurs with reduced frequency among persons travelling to low-risk areas from other low- or other high-risk areas, and there remain areas of intermediate risk, this review looks primarily at the illness occurring in persons from industrialised regions visiting high-risk regions of Latin America, Africa and Southern Asia. The material reviewed deals with the high frequency of acquiring diarrhoea during international travel to high-risk areas, seen in approximately 40%, and the expected bacterial causes of illness, of which diarrhoeagenic Escherichia coli is the most important. The host risk factors associated with increased susceptibility to diarrhoea include young age, lack of previous travel to high-risk regions in the past 6 months, indiscriminate food and beverage selection patterns, and host genetics. It appears feasible to decrease the rate of illness among the travelling public by careful food and beverage selection or through chemoprophylaxis with nonabsorbed rifaximin. Chemoprophylaxis with rifaximin should help to reduce the occurrence of travellers' diarrhoea and hopefully prevent post-diarrhoea complications, including irritable bowel syndrome. Early empirical therapy with antibacterial drugs, including rifaximin, a fluoroquinolone or azithromycin, will decrease the duration of illness and return

Objective: Framed in the patients’ engagement perspective, the current study aims to determine the effects of group music therapy in addition to drug care in comparison with drug care in addition to other non-expressive group activities in the treatment of psychiatric outpatients. Method: Participants (n = 27) with ICD-10 diagnoses of F20 (schizophrenia), F25 (schizoaffective disorders), F31 (bipolar affective disorder), F32 (depressive episode), and F60 (specific personality disorders) were randomized to receive group music therapy plus standard care (48 weekly sessions of 2 h) or standard care only. The clinical measures included dosages of neuroleptics, benzodiazepines, mood stabilizers, and antidepressants. Results: The participants who received group music therapy demonstrated greater improvement in drug dosage with respect to neuroleptics than those who did not receive group music therapy. Antidepressants had an increment for both groups that was significant only for the control group. Benzodiazepines and mood stabilizers did not show any significant change in either group. Conclusion: Group music therapy combined with standard drug care was effective for controlling neuroleptic drug dosages in adult psychiatric outpatients who received group music therapy. We discussed the likely applications of group music therapy in psychiatry and the possible contribution of music therapy in improving the psychopathological condition of adult outpatients. In addition, the implications for the patient-centered perspective were also discussed. PMID:27774073

Conclusions: Group music therapy combined with standard drug care is effective for controlling neuroleptic drug dosages in adult psychiatric outpatients who received group music therapy. We discuss the likely applications of group music therapy in psychiatry and the possible contribution of music therapy in improving the psychopathological condition of adult outpatients. In addition, the implications for the patient-centred perspective were also discussed.

Falls are a leading cause of morbidity, healthcare use and mortality. Dance is a popular form of physical activity among older people and previous research has suggested that it may improve various health outcomes in this population, including balance, gait and muscle performance. A systematic review of the potential benefits of dance on falls and fear of falling is lacking. Thus, we conducted a systematic review considering all randomized controls trials (RCTs) investigating if dance can reduce falls and improve fear of falling in older adults. Major databases were searched from inception until 1 March 2017 and a total of 10 RCTs were identified, which included a total of 680 people (n=356 dance, n=324 control). Overall, the mean age of the samples was 69.4 years, and 75.2% were female. Across four RCTs, dance therapy reduced falls versus usual care in only one study. Dance therapy improved fear of falling in two out of three included RCTs. There were no serious adverse events reported in the RCTs. In summary, we found a paucity of studies investigating the effect of dance on falls and fear of falling and the evidence base is preliminary and equivocal. Given the heterogeneity of the included samples and interventions, in addition to the short-term follow-up, no firm conclusions can be drawn. However, dance appears to be safe and, given its popularity and demonstrated benefits on other health/wellbeing outcomes in older adults, it is important that future research considers its potential benefits on falls/fear of falling in older age.

Diabetes Insipidus (DI) is either due to deficient secretion of arginine vasopressin (central) or to tubular unresponsiveness (nephrogenic). Drug induced DI is a well-known entity with an extensive list of medications. Polyuria is generally defined as urine output exceeding 3 liters per day in adults. It is crucial to identify the cause of diabetes insipidus and to implement therapy as early as possible to prevent the electrolyte disturbances and the associated mortality and morbidity. It is very rare to have an idiosyncratic effect after a short use of a medication, and physicians should be aware of such a complication to avoid volume depletion. The diagnosis of diabetes insipidus is very challenging because it relies on laboratory values, urine output, and the physical examination of the patient. A high clinical suspicion of diabetes insipidus should be enough to initiate treatment. The complications related to DI are mostly related to the electrolyte imbalance that can affect the normal physiology of different organ systems. PMID:24977135

Elderly patients (age ≥ 65 years old) use up to 30% of all commonly prescribed medication, and they suffer more their adverse effects than the general population. In order to minimize this risk, physicians should avoid polypharmacy, dangerous pharmacological interactions and take into account pharmacodynamic and senile pharmacokinetic changes before prescribing any medication to the elderly. The present review article originally describes how renal physiology changes secondary to aging such as dysautonomia, glomerular filtration rate reduction, tubular back-filtration, sodium, calcium and magnesium loss, potassium retention, altered dilution-concentration capability, tubular frailty, genetics, internal milieu and body composition are senile changes that when combined predispose elderly people to suffer from pharmacological adverse effects. Knowledge of these physiological modifications associated with aging and their impact on the pharmacology of particular drugs may help to optimize drug use and to avoid complications in this age group.

This case report describes the use of Spiritual Self-Schema (3-S) therapy in the treatment of an HIV-positive inner-city drug user maintained on methadone and referred for additional treatment due to unremitting cocaine use. 3-S therapy is a manual-guided intervention based on cognitive self-schema theory. Its goal is to help the patient create, elaborate, and make accessible a cognitive schema--the "spiritual" self-schema-that is incompatible with drug use and other HIV risk behaviors. 3-S therapy facilitates a cognitive shift from the habitual activation of the "addict" self-schema, with its drug-related cognitions, scripts and action plans, to the "spiritual" self-schema, with its associated repertoire of harm reduction beliefs and behaviors.

To prevent medication errors in drug handling in a paediatric ward. One in five preventable adverse drug events in hospitalised children is caused by medication errors. Errors in drug prescription have been studied frequently, but data regarding drug handling, including drug preparation and administration, are scarce. A three-step intervention study including monitoring procedure was used to detect and prevent medication errors in drug handling. After approval by the ethics committee, pharmacists monitored drug handling by nurses on an 18-bed paediatric ward in a university hospital prior to and following each intervention step. They also conducted a questionnaire survey aimed at identifying knowledge deficits. Each intervention step targeted different causes of errors. The handout mainly addressed knowledge deficits, the training course addressed errors caused by rule violations and slips, and the reference book addressed knowledge-, memory- and rule-based errors. The number of patients who were subjected to at least one medication error in drug handling decreased from 38/43 (88%) to 25/51 (49%) following the third intervention, and the overall frequency of errors decreased from 527 errors in 581 processes (91%) to 116/441 (26%). The issue of the handout reduced medication errors caused by knowledge deficits regarding, for instance, the correct 'volume of solvent for IV drugs' from 49-25%. Paediatric drug handling is prone to errors. A three-step intervention effectively decreased the high frequency of medication errors by addressing the diversity of their causes. Worldwide, nurses are in charge of drug handling, which constitutes an error-prone but often-neglected step in drug therapy. Detection and prevention of errors in daily routine is necessary for a safe and effective drug therapy. Our three-step intervention reduced errors and is suitable to be tested in other wards and settings. © 2014 John Wiley & Sons Ltd.
Full Text Available Background and Design: Striae gravidarum (SG has been reported to be associated with various factors, but the role of complementary therapies in the prevention of SG is still not well understood. The aim of this study was to determine complementary therapies for prevention of SG. Materials and Methods: This descriptive research was conducted on 120 pregnant women in a maternity clinic at a university hospital. Of 120 women, 49 were going through the last trimester and 71 were going through their first postpartum 24 hours. Data were collected using a 25-item-questionnaire through face-to-face interviews between June and July in 2016. Obtained data were evaluated by using descriptive statistics, chi-square test and the Kruskal-Wallis test. Results: 90.8% of women had SG. For the prevention of SG, 46.7% of women used massage, a manipulative body-based complementary therapy, 55.2% used oils, 28.6% used creams and 8.0% used a mixture of creams and oils for massaging. 42.9% of women started to use complementary therapies in their first trimester. Half of the women stated that they had received information about complementary therapies. A significantly lower rate of women using massage had SG compared to those not using massage (p=0.023. Conclusion: It was concluded that nearly half of the women used massage for the prevention of SG. In addition, massage application was found to reduce the occurrence of SG.

Background Numerous observational studies suggest that preventable adverse drug reactions are a significant burden in healthcare, but no meta-analysis using a standardised definition for adverse drug reactions exists. The aim of the study was to estimate the percentage of patients with preventable adverse drug reactions and the preventability of adverse drug reactions in adult outpatients and inpatients. Methods Studies were identified through searching Cochrane, CINAHL, EMBASE, IPA, Medline, PsycINFO and Web of Science in September 2010, and by hand searching the reference lists of identified papers. Original peer-reviewed research articles in English that defined adverse drug reactions according to WHO’s or similar definition and assessed preventability were included. Disease or treatment specific studies were excluded. Meta-analysis on the percentage of patients with preventable adverse drug reactions and the preventability of adverse drug reactions was conducted. Results Data were analysed from 16 original studies on outpatients with 48797 emergency visits or hospital admissions and from 8 studies involving 24128 inpatients. No studies in primary care were identified. Among adult outpatients, 2.0% (95% confidence interval (CI): 1.2–3.2%) had preventable adverse drug reactions and 52% (95% CI: 42–62%) of adverse drug reactions were preventable. Among inpatients, 1.6% (95% CI: 0.1–51%) had preventable adverse drug reactions and 45% (95% CI: 33–58%) of adverse drug reactions were preventable. Conclusions This meta-analysis corroborates that preventable adverse drug reactions are a significant burden to healthcare among adult outpatients. Among both outpatients and inpatients, approximately half of adverse drug reactions are preventable, demonstrating that further evidence on prevention strategies is required. The percentage of patients with preventable adverse drug reactions among inpatients and in primary care is largely unknown and should be

Drug counterfeiting has serious public health and safety implications. The objective of this study was to systematically review the evidence on the effectiveness of interventions to combat or prevent drug counterfeiting. We searched multiple electronic databases and the grey literature up to March 2014. Two reviewers completed, in duplicate and independently, the study selection, data abstraction and risk of bias assessment. We included randomised trials, non-randomised studies, and case studies examining any intervention at the health system-level to combat or prevent drug counterfeiting. Outcomes of interest included changes in failure rates of tested drugs and changes in prevalence of counterfeit medicines. We excluded studies that focused exclusively on substandard, degraded or expired drugs, or that focused on medication errors. We assessed the risk of bias in each included study. We reported the results narratively and, where applicable, we conducted meta-analyses. We included 21 studies representing 25 units of analysis. Overall, we found low quality evidence suggesting positive effects of drug registration (OR=0.23; 95% CI 0.08 to 0.67), and WHO-prequalification of drugs (OR=0.06; 95% CI 0.01 to 0.35) in reducing the prevalence of counterfeit and substandard drugs. Low quality evidence suggests that licensing of drug outlets is probably ineffective (OR=0.66; 95% CI 0.41 to 1.05). For multifaceted interventions (including a mix of regulations, training of inspectors, public-private collaborations and legal actions), low quality evidence suggest they may be effective. The single RCT provided moderate quality evidence of no effect of 'two extra inspections' in improving drug quality. Policymakers and stakeholders would benefit from registration and WHO-prequalification of drugs and may also consider multifaceted interventions. Future effectiveness studies should address the methodological limitations of the available evidence. PROSPERO CRD42014009269

Delirium is a relevant condition in critically ill patients with long-term impacts on mortality, cognitive and functional status and quality of life. Despite the progress in its diagnosis, prevention and management during the last years, its impact persists being relevant, so new preventive and therapeutic strategies need to be explored. Among non-pharmacologic preventive strategies, recent reports suggest a role for occupational therapy through a series of interventions that may impact the development of delirium. The aim of this review is to evaluate the studies evaluating the role of occupational therapy in the prevention of delirium in critically ill patient populations, and suggests perspectives to future research in this area.

Full Text Available Tuberculosis appears to be a disease as old as human history. Tuberculosis is of great public health importance in the developing countries. Its clinical profile is different in developing countries in comparison to countries of Europe and North America. The recent epidemic of HIV has slowed down the declining trend in the incidence of tuberculosis. Bacilli are transmitted from one infected person to the others as an aerosol. In some cases contaminated milk may also be responsible. However despite effective regimens and addition of new drugs and improved pharmacokinetic knowledge the chemotherapy of tuberculosis still remains a challenge. Poor drug-compliance by patients being one of the foremost reason for frequent relapses and bacterial resistance. Some important and concrete steps to meet these challenges have been judicious use of two or more bactericidal drugs and introduction of short courses regiment. Multiple drugs therapy may shorten the duration of treatment and prevent emergence of drug resistance.

The story began on 11th May 1857 when Charles Locock commented in the Lancet on his use of potassium bromide in 15 cases of "hysterical" epilepsy in young women. The next development was the serendipitous discovery of the anticonvulsant properties of phenobarbital by Alfred Hauptmann in 1912. This predated by more than 20 years the screening of potential therapeutic agents against "electrical seizures" in cats by Houston Merritt and Tracy Putnam. The result was the launching of phenytoin in 1938. Next came primidone, ethosuximide, carbamazepine and valproic acid, all of which can be regarded as first generation antiepileptic drugs (AEDs). Shortly after their synthesis, the benzodiazepines were rapidly recognised as having anticonvulsant activity. The modern era focused on the systematic screening of many thousands of compounds against rodent seizure models under the Anticonvulsant Drug Development Program in the US. This resulted in the global licensing, in chronological order, of vigabatrin, zonisamide, oxcarbazepine, lamotrigine, felbamate, gabapentin, topiramate, tiagabine, levetiracetam, pregabalin and lacosamide. Rufinamide is available in the US and Europe for Lennox-Gastaut syndrome and stiripentol has been made available for Dravet syndrome under the European orphan drug scheme. Eslicarbazepine can be prescribed in Europe for partial seizures, but not in the US. Has all this activity improved the lives of people with epilepsy? The short answer is-probably yes, but not by very much! This paper will conclude with a précis of the views of a selected group of paediatric and adult epileptologists on the advances in pharmacological management achieved over the last 20 years.

Full Text Available Photodynamic therapy (PDT is a non-invasive combinatorial therapeutic modality using light, photosensitizer (PS, and oxygen used for the treatment of cancer and other diseases. When PSs in cells are exposed to specific wavelengths of light, they are transformed from the singlet ground state (S0 to an excited singlet state (S1–Sn, followed by intersystem crossing to an excited triplet state (T1. The energy transferred from T1 to biological substrates and molecular oxygen, via type I and II reactions, generates reactive oxygen species, (1O2, H2O2, O2*, HO*, which causes cellular damage that leads to tumor cell death through necrosis or apoptosis. The solubility, selectivity, and targeting of photosensitizers are important factors that must be considered in PDT. Nano-formulating PSs with organic and inorganic nanoparticles poses as potential strategy to satisfy the requirements of an ideal PDT system. In this review, we summarize several organic and inorganic PS carriers that have been studied to enhance the efficacy of photodynamic therapy against cancer.

Full Text Available A recently published paper addressed the interesting topic of prevention of erectile dysfunction (ED with tadalafil, a phosphodiesterase-type 5 inhibitor (PDE5i in patients undergoing radiation therapy for localized prostate cancer.  Tadalafil 5 mg or placebo was administered once-daily for 24 weeks in patients undergoing external-beam radiotherapy (EBRT or brachytherapy (BT for prostate cancer. This randomized trial did not show superior efficacy of the active drug compared with placebo 4-6 weeks after stopping the study drug. Furthermore, patients younger than 65 years did not respond significantly better than older patients.
Full Text Available Lumbar disc degeneration is a disorder whose clinical manifestations are represented by episodic pain in the lumbar spine, without lumbar blockage and minor muscle contraction. Because lumbalgia caused by lumbar disc degeneration is not always very high intensity pain, the easiest to apply treatment is drug therapy. The aim of this study was to analyze the potential role of rehabilitation treatment in the recovery of patients and the prevention of complications compared to drug therapy alone. The study included 28 patients (17 women and 11 men aged between 23-60 years, assigned to two groups: 20 patients who received rehabilitation treatment (consisting of massage, kinesiotherapy, hydrokinesiotherapy, electrotherapy and medication and 8 patients who received drug treatment consisting of anti-inflammatory and analgesic drugs. The treatment duration was 10 days. For the evaluation of pain, the visual analogue scale was used, for the degree of disability, the Oswestry questionnaire, and for joint mobility and muscle strength, articular and muscular testing. At the end of treatment, the study group compared to the control group had a statistically significant result for pain (p=0.001, as well as for the Oswestry score (p=0.030. The mean age of the patients was 35.51±3.026, which shows an increased incidence among young adults. A possible connection between the development of the disease in women and age less than 45 years was also investigated, but the result was not statistically significant, p=0.22. Our data suggest the fact that rehabilitation treatment plays an important role in the reduction of pain and the improvement of the quality of life of patients with lumbar disc degeneration by decreasing the degree of disability. In the future, it can be proposed to monitor patients with lumbar disc degeneration over a longer time period in order to see the effects of kinetic rehabilitation programs in relation to the delay of chronicization.

Full Text Available Introduction. The formation of responsibility for one’s health in the youth environment is one of the tasks of the institution of education that determines the process of socialization. The future of sustainable development of country is determined, among other things, by the formation of negative social attitudes towards drug use.The aim of the publication is to study the specifics of the social orientation among young people on drug use and to justify the need for prevention in the educational environment.Methodology and research methods. Methodological basis of work involves classical theories of social installation; anomies; cultural conflict; subcultures; stigmatizations; social control; social space. The analysis and synthesis of scientific publications and data of the government statistics, including results of a number of social researches of 2010–2015 conducted in the Tyumen region are used. Sociological methods, including poll, questioning and the formalized interviews are applied at an experimental investigation phase. Data processing is carried out in technique of the factorial and classification analysis.Results and scientific novelty. Drug abuse among young people is a result of the contradiction between youth attitudes and social norms. It is shown that the prevention of drug abuse in Russia is institutionally ineffective. The social attitudes and motives connected with drug abuse among young people aged 18–30 years are revealed. It is established that acceptance of drug abuse experience is not defined by a gender, social and/or material status. The main types of the attitude to drug abuse experience are designated: 1 complete negation of a possibility of drug abuse; 2 refusal of drug abuse, but indifference or loyal attitude to drug abuse by others; 3 readiness for periodic drug usage; 4 steady stereotype of regular use of narcotic substances.The necessity of flexible forms of influence on youth for formation of sustainable

Stroke is an important cause of death and disability. However, about two thirds of cerebrovascular events are initially minor. They carry a high risk of potentially severe recurrent events, but they also offer an opportunity for secondary prevention to avoid such recurrences. As most recurrent events occur within a short time after the initial presentation, secondary prevention has to be started as soon as possible. Dramatic risk reduction can be achieved with well-established drugs if used in a timely manner. A standard secondary preventive regimen will address multiple vascular risk factors and will usually consist of an antiplatelet agent, a lipid lowering drug, and an antihypertensive agent. Depending on the risk factor profile of each patient, this will have to be adjusted individually, for example, taking into account the presence of cardioembolism or of stenotic disease of the brain-supplying arteries. In recent years, the approach to treating these risk factors has evolved. In addition to absolute blood pressure, blood pressure variability has emerged as an important contributing factor to stroke risk, which is affected differently by different antihypertensive agents. New oral anticoagulants reduce the risk of cerebral haemorrhage and the need for regular blood checks. The best antiplatelet regimen for stroke prevention is still uncertain, and treatment of dyslipidaemia may change if trials with cholesteryl ester transfer protein (CETP) inhibitors, which increase levels of HDL-cholesterol, are successful. This article reviews the current evidence for drug treatments in the secondary prevention of ischaemic stroke. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Social marketing involves applying marketing principles to promote social goods. In the context of health behavior, it has been used successfully to reduce alcohol-related car crashes, smoking among youths, and malaria transmission, among other goals. Features of social marketing, such as audience segmentation and repeated exposure to prevention messages, distinguish it from traditional health promotion programs. A recent review found 8 of 10 rigorously evaluated social marketing interventions responsible for changes in HIV-related behavior or behavioral intentions. We studied 479 injection drug users to evaluate a community-based social marketing campaign to reduce injection risk behavior among drug users in Sacramento, California. Injecting drugs is associated with HIV infection in more than 130 countries worldwide.
Sexual offenders are a heterogeneous group of offenders with different personality structures and different patterns of crime. As a consequence, difficulties arise with the definition of sexually deviant or offending behaviour, which depends on period of time and culture. After presenting the actual definition of sexual offences, their frequency is shown by means of German epidemiological data. The problem of the assumed relationship between paraphilia and sexual offending behaviour is called into question. After the description of the central neurobiological and endocrinological mechanisms, the established pharmacological treatment strategies (Selective Serotonine Reuptake Inhibitors, Antiadrogenes, LHRH (Luteotropic Hormone Releasing Hormone)-Agonists) are presented. Finally, the step-wise algorithm for the therapy of sexual according to Bradford is presented.
Full Text Available Available information suggests that nonadherence with medication is a common problem in pregnant women. Not taking prescribed drugs may have potentially negative consequences as patients may not achieve their therapeutic goal. In addition to the many factors that may influence medication-taking behaviour in the general population, unique challenges are encountered in pregnant women as both maternal health and fetal well-being must be considered. On the one hand, pregnant women may be motivated to keep their underlying disease under control, while, on the other hand, fear and anxiety regarding the potential harmful effects of their medication on their unborn child may result in poor adherence with needed medication. Providing evidence-based information, ideally preconceptually, regarding the effects of their medication during pregnancy may be important in avoiding misperceptions that lead to nonadherence.

Deregulation of angiogenesis--the growth of new blood vessels from an existing vasculature--is a main driving force in many severe human diseases including cancer. As such, tumor angiogenesis is important for delivering oxygen and nutrients to growing tumors, and therefore considered an essential pathologic feature of cancer, while also playing a key role in enabling other aspects of tumor pathology such as metabolic deregulation and tumor dissemination/metastasis. Recently, inhibition of tumor angiogenesis has become a clinical anti-cancer strategy in line with chemotherapy, radiotherapy and surgery, which underscore the critical importance of the angiogenic switch during early tumor development. Unfortunately the clinically approved anti-angiogenic drugs in use today are only effective in a subset of the patients, and many who initially respond develop resistance over time. Also, some of the anti-angiogenic drugs are toxic and it would be of great importance to identify alternative compounds, which could overcome these drawbacks and limitations of the currently available therapy. Finding "the most important target" may, however, prove a very challenging approach as the tumor environment is highly diverse, consisting of many different cell types, all of which may contribute to tumor angiogenesis. Furthermore, the tumor cells themselves are genetically unstable, leading to a progressive increase in the number of different angiogenic factors produced as the cancer progresses to advanced stages. As an alternative approach to targeted therapy, options to broadly interfere with angiogenic signals by a mixture of non-toxic natural compound with pleiotropic actions were viewed by this team as an opportunity to develop a complementary anti-angiogenesis treatment option. As a part of the "Halifax Project" within the "Getting to know cancer" framework, we have here, based on a thorough review of the literature, identified 10 important aspects of tumor angiogenesis and the

One of the mechanisms of external signal transduction (ionizing radiation, toxicants, stress) to the target cell is the existence of membrane and intracellular proteins with intrinsic tyrosine kinase activity. No wonder that etiology of malignant growth links to abnormalities in signal transduction through tyrosine kinases. The epidermal growth factor receptor (EGFR) tyrosine kinases play fundamental roles in development, proliferation and differentiation of tissues of epithelial, mesenchymal and neuronal origin. There are four types of EGFR: EGF receptor (ErbB1/HER1), ErbB2/Neu/HER2, ErbB3/HER3 and ErbB4/HER4. Abnormal expression of EGFR, appearance of receptor mutants with changed ability to protein-protein interactions or increased tyrosine kinase activity have been implicated in the malignancy of different types of human tumors. Bioinformatics is currently using in investigation on design and selection of drugs that can make alterations in structure or competitively bind with receptors and so display antagonistic characteristics.

Study Objectives: REM sleep behavior disorder (RBD) is characterized by loss of the normal muscle atonia during REM sleep associated with disruptive motor activity related to the acting out of dreams. There is frequently injury to the patient or bed partner, and treatment is usually required. Clonazepam has been the first-line therapy for many years, with 2 large case series reporting efficacy with few side effects in the majority of patients. However, long-acting hypnotics in the elderly or those with cognitive impairment can be associated with adverse events especially unacceptable daytime sedation, confusion, and exacerbation of existing sleep apnea. Methods: We reviewed 39 patients with confirmed RBD who were treated within our regional sleep center, assessing both efficacy and side effects of drug therapies. Results: Adverse effects were reported by 58% of the patients using clonazepam, with 50% either discontinuing the drug or reducing the dose. This prompted us review the side effects of clonazepam in detail and to look for alternative therapies. We report several novel and effective therapies, in particular zopiclone, in a series of patients under long-term follow-up for RBD. Conclusions: There are alternatives to clonazepam therapy for RBD which can be as effective and may be better tolerated. Citation: Anderson KN; Shneerson JM.

Full Text Available Abstract Parkinson`s disease (PD is a progressive, disabling neurodegenerative disorder with onset of motor and non-motor features. Both reduce quality of life of PD patients and cause caregiver burden. This review aims to provide a survey of possible therapeutic options for treatment of motor and non motor symptoms of PD and to discuss their relation to each other. MAO-B-Inhibitors, NMDA antagonists, dopamine agonists and levodopa with its various application modes mainly improve the dopamine associated motor symptoms in PD. This armentarium of PD drugs only partially influences the onset and occurrence of non motor symptoms. These PD features predominantly result from non dopaminergic neurodegeneration. Autonomic features, such as seborrhea, hyperhidrosis, orthostatic syndrome, salivation, bladder dysfunction, gastrointestinal disturbances, and neuropsychiatric symptoms, such as depression, sleep disorders, psychosis, cognitive dysfunction with impaired execution and impulse control may appear. Drug therapy of these non motor symptoms complicates long-term PD drug therapy due to possible occurrence of drug interactions, - side effects, and altered pharmacokinetic behaviour of applied compounds. Dopamine substituting compounds themselves may contribute to onset of these non motor symptoms. This complicates the differentiation from the disease process itself and influences therapeutic options, which are often limited because of additional morbidity with necessary concomitant drug therapy.

The emergent interest in cancer epigenetics stems from the fact that epigenetic modifications are implicated in virtually every step of tumorigenesis. More interestingly, epigenetic changes are reversible heritable changes that are not due to the alteration in DNA sequence but have potential to alter gene expression. Dietary agents consist of many bioactive ingredients which actively regulate various molecular targets involved in tumorigenesis. We present evidence that numerous bioactive dietary components can interfere with various epigenetic targets in cancer prevention and therapy. These agents include curcumin (turmeric), genistein (soybean), tea polyphenols (green tea), resveratrol (grapes), and sulforaphane (cruciferous vegetables). These bioactive components alter the DNA methylation and histone modifications required for gene activation or silencing in cancer prevention and therapy. Bioactive components mediate epigenetic modifications associated with the induction of tumor suppressor genes such as p21(WAF1/CIP1) and inhibition of tumor promoting genes such as the human telomerase reverse transcriptase during tumorigenesis processes. Here, we present considerable evidence that bioactive components and their epigenetic targets are associated with cancer prevention and therapy which should facilitate novel drug discovery and development. In addition, remarkable advances in our understanding of basic epigenetic mechanisms as well as the rapid progress that is being made in developing powerful new technologies, such as those for sensitive and quantitative detection of epigenetic and epigenomic changes in cancer biology, hold great promise for novel epigenetic approaches to cancer prevention and therapy.

Cardioembolic strokes account for one-sixth of all strokes and are an important potentially preventable cause of morbidity and mortality. Vitamin K antagonists (e.g., warfarin) are effective for the prevention of cardioembolic stroke in patients with atrial fibrillation (AF) and in those with mechanical heart valves but because of their inherent limitations are underutilized and often suboptimally managed. Antiplatelet therapies have been the only alternatives to warfarin for stroke prevention in AF but although they are safer and more convenient they are much less efficacious. The advent of new oral anticoagulant drugs offers the potential to reduce the burden of cardioembolic stroke by providing access to effective, safe, and more convenient therapies. New oral anticoagulants have begun to replace warfarin for stroke prevention in some patients with AF, based on the favorable results of recently completed phase III randomized controlled trials, and provide for the first time an alternative to antiplatelet therapy for patients deemed unsuitable for warfarin. The promise of the new oral anticoagulants in patients with mechanical heart valves is currently being tested in a phase II trial. If efficacy and safety are demonstrated, the new oral anticoagulants will provide an alternative to warfarin for patients with mechanical heart valves and may also lead to increased use of mechanical valves for patients who would not have received them in the past because of the requirement for long term warfarin therapy.

Spontaneous hemorrhage in the kidney, also known as Wunderlich Syndrome, is a rare clinical problem. The most common cause of spontaneous renal hemorrhage is tumor. Other causes are rupture of a renal cyst, vasculitis, hydronephrosis, preeclampsia, and kidney infections. A 67-year-old man was admitted complaining left flank colic pain. A contrast CT scan showed the presence of a subcapsular hematoma of the left kidney extending from the upper to the lower pole. He had no history of trauma and immunological screening tests for vasculitis were normal. His current therapy included acetylsalicylic acid (100 mg/daily) and lisinopril (20 mg/ daily). The patient was hospitalized for 4 days and his circulatory state remained stable. Nine months later an ultrasound examination showed complete resolution of the hematoma. One year later the patient was admitted again because of a spontaneous right calf hematoma and a thoroughly investigation of his coagulation pattern was carried out. Laboratory finding revealed a platelet defect, as the number of adenine nucleotides and other marker related to platelet activation were increased: ADP 1 mcM lack 2 masculine wave, ADP 2 mcM lack 2 masculine wave, Adrenalina 5 mcM lack 2 masculine wave, Adrenalina 10 mcM lack 2 masculine wave. Platelet activation markers: Gp53 in lysosomal membrane 0.48 Dpar (0 - 0.26). Our case describes the recurrence of spontaneous hemorrhages (perirenal and intramuscular hematoma) as a result of an underlying platelet aggregation defect worsened by administration of acetylsalicylic acid. In patients on antiplatelet treatment with a history of excessive bleeding a thorough investigation of coagulation status appears beneficial.

This paper describes the goals and current practice of school-based random student drug testing (RSDT) as part of an overall drug prevention strategy, briefly explores the available literature evaluating its effectiveness and discusses the controversies related to RSDT. The authors describe the rationale for RSDT programs and the prevalence of RSDT and other drug testing programs in schools. Eight major criticisms and controversies in RSDT are discussed, including those related to acceptance of RSDT, program effectiveness, costs, legality and effects of drug testing on students. The limitations of the current literature are explored. Although there is limited empirical evidence to support or refute the efficacy of RSDT in schools, there remains substantial opposition to such programs, which may contribute to the paucity of empirical studies of RSDT. Rigorous long-term evaluations are needed to evaluate the effectiveness of various versions of RSDT programs to prevent drug use and identify students in need of assistance to become and stay drug-free. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

Polypathological patients are usually elderly and take numerous drugs. Polypharmacy affects 85% of these individuals and is not associated with greater survival. On the contrary, polypharmacy exposes these individuals to more adverse effects, such as weight loss, falls, functional and cognitive impairment and hospitalisations. The complexity of a drug regimen covers more aspects than the simple number of drugs consumed. The galenic form, the dosage and the method for preparing the drug can impede the understanding of and compliance with prescriptions. Both polypharmacy and therapeutic complexity are associated with poorer adherence by patients. To prevent polypharmacy, reduce complexity and improve adherence, the appropriate use of drugs is needed. Proper prescribing consists of selecting drugs that have clear evidence for their use in the indication, which are appropriate for the patient's circumstances, are well tolerated and cost-effective and whose benefits outweigh the risks. To improve the drug prescription, periodic reviews of the drugs need to be conducted, especially when the patient changes doctor and during healthcare transitions. The Beers and STOPP/START (Screening Tool of Older Person's potentially inappropriate Prescriptions/Screening Tool to Alert doctors to the Right Treatment) criteria are effective tools for this improvement. Deprescription for polymedicated polypathological patients that considers their clinical circumstances, prognosis and preferences can contribute to a more appropriate use of drugs.

Full Text Available Oxidative stress has been implicated in pathophysiology of aging and age-associated disease. Antioxidative medicine has become a practice for prevention of atherosclerosis. However, limited success in preventing cardiovascular disease (CVD in individuals with atherosclerosis using general antioxidants has prompted us to develop a novel antioxidative strategy to prevent atherosclerosis. Reducing visceral adipose tissue by calorie restriction (CR and regular endurance exercise represents a causative therapy for ameliorating oxidative stress. Some of the recently emerging drugs used for the treatment of CVD may be assigned as site-specific antioxidants. CR and exercise mimetic agents are the choice for individuals who are difficult to continue CR and exercise. Better understanding of molecular and cellular biology of redox signaling will pave the way for more effective antioxidative medicine for prevention of CVD and prolongation of healthy life span.

Pulmonary arterial hypertension (PAH) is a primary pulmonary arteriolar disease, characterized by a progressive increase in pulmonary vascular resistance and pressure in the pulmonary circulation. It progressively leads to hypertrophy of the right ventricle and with no treatment to its failure and patient´s death. Etiology of pulmonary hypertension (PH) has been reclassified repeatedly, most recently during the 4th World Symposium on Pulmonary Hypertension held in 2008 . Currently, the first group contains PAH with either unknown or known cause (systemic connective tissue disease, liver disease, congenital heart disease, HIV infection, abuse of anorexic agents). Current drug therapy of PAH is divided into conventional (anticoagulant therapy, calcium channel blockers, therapy of chronic heart failure) and specific (prostanoids, endothelium receptor antagonists, phosphodiesterase 5 inhibitors). Patients with positive vasodilator test are indicated for the high doses treatment of calcium channel blockers. Patients with negative vasodilator test are indicated for chronic anticoagulant therapy and specific drug therapy either as mono-therapy, or as combined therapy. Recent years have brought a wide range of new treatments modalities, especially in the field of pharmacotherapy. In addition, other treatment modalities have been tested, for example application of stem cells. Drugs in research include several groups: 1. vasodilators: fasudil, adrenonedullin, activators and stimulators of guanylate cyclase, vasoactive intestinal peptide (VIP); 2. Anti-inflammatory agents: inhibitor of elastase, antagonist of B cells, immunosuppressive agents, inhibitor of HDAC1; 3. agents affecting metabolism: nitrites, PPAR antagonists, antioxidants, serotonin receptor antagonist and serotonin transporter blockers, statins, inhibitors of Rho-kinase; 4. apoptosis inductors of smooth muscle cells: tyrosine-kinase inhibitors, elastase inhibitors; 5. agents influencing vascular regeneration

Full Text Available In addition to their therapeutic effects on malignant cells, cytotoxic agents have the potential of causing destruction of healthy, normal cells. Extravasation of the drug can produce extensive necrosis of the skin and subcutaneous tissue. Management of these extravasational effects differs from one centre to another and prevention is usually strongly emphasized. We analyzed our management of 12 patients referred to us over five years with extravasation of cytotoxic drugs and reviewed the literature for different approaches with regard to prophylaxis and management of extravasational effects. Materials and Methods: This study was done in the department of plastic surgery of a medical college. Five years of retrospective data were studied of patients referred to our department with extravasation of cytotoxic drugs. Results: We managed 12 cases referred to our department with extravasation of cytotoxic drugs. Mitomycin C was used in seven cases (58.33%, vincristine in two cases (16.66%, 5-Florouracil in another two cases while doxorubicin was responsible for extravasational side effects in one case (8.33%. The size of necrosis ranged from 3.75 cm 2 to 25 cm 2 with average size of 9.6 cm 2 . In terms of the area involved, the dorsum of the hand was involved in five cases (41.66%, the wrist in another five cases (41.66%, and the cubital fossa in the remaining two cases (16.66%. All cases were treated with daily debridement of necrotic tissue, saline dressing, and split skin grafting. Conclusion: Extravasation of cytotoxic drugs further increases the suffering of cancer patients. This catastrophe can only be avoided by vigilance and immediate application of antidotes. Once the local toxicity of the drugs takes effect, morbidity is unavoidable

Full Text Available During the past decade, overall results of treatment of multiple myeloma (MM have been improved and survival curves are now significantly better with respect to those obtained with historical treatment. These improvements are linked to a deeper knowledge of the biology of disease and to the introduction in clinical practice of drugs with different mechanism of action such as proteasome inhibitors and immunomodulatory drugs (IMiDs. However, MM remains in most cases an incurable disease. For patients who relapse after treatment with novel agents, the prognosis is dismal and new drugs and therapeutic strategies are required for continued disease control. In this review, we summarize new insights in salvage therapy for relapsed/refractory MM as emerging from recent clinical trials exploring the activity of bendamustine, new generation proteasome inhibitors, novel IMiDs, monoclonal antibodies, and drugs interfering with growth pathways.

The prevalence of dental caries in the school children population in Rieti is very high, according to low levels of fluoride content in drinkable water, similar to those detected in other areas of Italy and Europe. The aim of our research is to propose a combined prevention protocol, utilizing fluoride tablets and dental therapy through structures already existing in the public health national organization. The application of this combined (profilaxis-therapy) protocol is expected to decrease the prevalence of dental caries to 50% in a five years period, at a very accettable cost. This protocol should find early application, possibly starting from maternal schools.

A variety of human cancers, including nonsmall cell lung (NSCLC), breast, and colon cancers, are driven by the human epidermal growth factor receptor (HER) family of receptor tyrosine kinases. Having shown that bisphosphonates, a class of drugs used widely for the therapy of osteoporosis and metastatic bone disease, reduce cancer cell viability by targeting HER1, we explored their potential utility in the prevention and therapy of HER-driven cancers. We show that bisphosphonates inhibit colony formation by HER1(ΔE746-A750)-driven HCC827 NSCLCs and HER1(wt)-expressing MB231 triple negative breast cancers, but not by HER(low)-SW620 colon cancers. In parallel, oral gavage with bisphosphonates of mice xenografted with HCC827 or MB231 cells led to a significant reduction in tumor volume in both treatment and prevention protocols. This result was not seen with mice harboring HER(low) SW620 xenografts. We next explored whether bisphosphonates can serve as adjunctive therapies to tyrosine kinase inhibitors (TKIs), namely gefitinib and erlotinib, and whether the drugs can target TKI-resistant NSCLCs. In silico docking, together with molecular dynamics and anisotropic network modeling, showed that bisphosphonates bind to TKIs within the HER1 kinase domain. As predicted from this combinatorial binding, bisphosphonates enhanced the effects of TKIs in reducing cell viability and driving tumor regression in mice. Impressively, the drugs also overcame erlotinib resistance acquired through the gatekeeper mutation T790M, thus offering an option for TKI-resistant NSCLCs. We suggest that bisphosphonates can potentially be repurposed for the prevention and adjunctive therapy of HER1-driven cancers.

Background and purpose: We previously demonstrated that radiation may arrest tumor cells at G2 phase, which in turn prevents the cytotoxicity of antimicrotubule drugs and results in antagonistic interaction between these two modalities. Herein we tested whether G2 abrogators would attenuate the above antagonistic interaction and improve the therapeutic efficacy of combination therapy between radiation and antimicrotubule drugs. Materials and methods: Breast cancer BCap37 and epidermoid carcinoma KB cell lines were administered with radiation, UCN-01 (a model drug of G2 abrogator), paclitaxel or vincristine, alone or in combinations. The antitumor activities of single and combined treatments were analyzed by a series of cytotoxic, apoptotic, cell cycle, morphological and biochemical assays. Results: UCN-01 significantly enhanced the cytotoxicity of radiation, antimitotic drugs, and their combined treatments in vitro. Further investigations demonstrated that UCN-01 attenuated radiation-induced G2 arrest, and subsequently repressed the inhibitory effect of radiation on drug-induced mitotic arrest and apoptosis. Conclusions: This is the first report demonstrating that G2 checkpoint abrogation represses the inhibitory effect of radiation on antimicrotubule drugs, which may be implicated in cancer combination therapy. Considering that G2 abrogators are under extensive evaluation for cancer treatment, our findings provide valuable information for this class of promising compounds.

Early initiation of antiretroviral therapy (ART) reduces the risk of drug-sensitive HIV transmission but may increase the transmission of drug-resistant HIV. We used a mathematical model to estimate the long-term population-level benefits of ART and determine the scenarios under which earlier ART (treatment at 1 year post-infection, on average) could decrease simultaneously both total and drug-resistant HIV incidence (new infections). We constructed an infection-age-structured mathematical model that tracked the transmission rates over the course of infection and modelled the patients' life expectancy as a function of ART initiation timing. We fitted this model to the annual AIDS incidence and death data directly, and to resistance data and demographic data indirectly among men who have sex with men (MSM) in San Francisco. Using counterfactual scenarios, we assessed the impact on total and drug-resistant HIV incidence of ART initiation timing, frequency of acquired drug resistance, and second-line drug effectiveness (defined as the combination of resistance monitoring, biomedical drug efficacy and adherence). Earlier ART initiation could decrease the number of both total and drug-resistant HIV incidence when second-line drug effectiveness is sufficiently high (greater than 80%), but increase the proportion of new infections that are drug resistant. Thus, resistance may paradoxically appear to be increasing while actually decreasing. © 2017 The Author(s).

Drug interactions are an on-going concern in the treatment of cancer, especially when targeted therapies, such as tyrosine kinase inhibitors (TKI) or mammalian target of rapamycin (mTOR) inhibitors, are being used. The emergence of elderly patients and/or patients with both cancer and other chronic co-morbidities leads to polypharmacy. Therefore, the risk of drug-drug interactions (DDI) becomes a clinically relevant issue, all the more so as TKIs and mTOR inhibitors are essentially metabolised by cytochrome P450 enzymes. These DDIs can result in variability in anticancer drug exposure, thus favouring the selection of resistant cellular clones or the occurrence of toxicity. This review provides a comprehensive overview of DDIs that involve targeted therapies approved by the FDA for the treatment of solid tumours for more than 3 years (sorafenib, sunitinib, erlotinib, gefitinib, imatinib, lapatinib, everolimus, temsirolimus) and medicinal herb or drugs. This review also provides some guidelines to help oncologists and pharmacists in their clinical practice. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

IMPORTANCE New data and therapeutic options warrant updated recommendations for the use of antiretroviral drugs (ARVs) to treat or to prevent HIV infection in adults. OBJECTIVE To provide updated recommendations for the use of antiretroviral therapy in adults (aged ≥18 years) with established HIV infection, including when to start treatment, initial regimens, and changing regimens, along with recommendations for using ARVs for preventing HIV among those at risk, including preexposure and postexposure prophylaxis. EVIDENCE REVIEW A panel of experts in HIV research and patient care convened by the International Antiviral Society-USA reviewed data published in peer-reviewed journals, presented by regulatory agencies, or presented as conference abstracts at peer-reviewed scientific conferences since the 2014 report, for new data or evidence that would change previous recommendations or their ratings. Comprehensive literature searches were conducted in the PubMed and EMBASE databases through April 2016. Recommendations were by consensus, and each recommendation was rated by strength and quality of the evidence. FINDINGS Newer data support the widely accepted recommendation that antiretroviral therapy should be started in all individuals with HIV infection with detectable viremia regardless of CD4 cell count. Recommended optimal initial regimens for most patients are 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (InSTI). Other effective regimens include nonnucleoside reverse transcriptase inhibitors or boosted protease inhibitors with 2 NRTIs. Recommendations for special populations and in the settings of opportunistic infections and concomitant conditions are provided. Reasons for switching therapy include convenience, tolerability, simplification, anticipation of potential new drug interactions, pregnancy or plans for pregnancy, elimination of food restrictions, virologic failure, or drug toxicities.

There is great interest in drugs that are capable of modulating multiple aging pathways, thereby delaying the onset and progression of aging. Effective strategies for drug development include the repurposing of existing drugs already approved by the FDA for human therapy. FDA approved drugs have known mechanisms of action and have been thoroughly screened for safety. Although there has been extensive scientific activity in repurposing drugs for disease therapy, there has been little testing of these drugs for their effects on aging. The pool of FDA approved drugs therefore represents a large reservoir of drug candidates with substantial potential for anti-aging therapy. In this paper we employ FINDSITE comb , a powerful ligand homology modeling program, to identify binding partners for proteins produced by temperature sensing genes that have been implicated in aging. This list of drugs with potential to modulate aging rates was then tested experimentally for lifespan and healthspan extension using a small invertebrate model. Three protein targets of the rotifer Brachionus manjavacas corresponding to products of the transient receptor potential gene 7, ribosomal protein S6 polypeptide 2 gene, or forkhead box C gene, were screened against a compound library consisting of DrugBank drugs including 1347 FDA approved, non-nutraceutical molecules. Twenty nine drugs ranked in the top 1 % for binding to each target were subsequently included in our experimental analysis. Continuous exposure of rotifers to 1 µM naproxen significantly extended rotifer mean lifespan by 14 %. We used three endpoints to estimate rotifer health: swimming speed (mobility proxy), reproduction (overall vitality), and mitochondria activity (cellular senescence proxy). The natural decline in swimming speed with aging was more gradual when rotifers were exposed to three drugs, so that on day 6, mean swimming speed of females was 1.19 mm/s for naproxen (P = 0.038), 1.20 for fludarabine (P = 0

Cost-effectivness analyses focused on benign thyroid diseases are under-represented in the literature. The calculation of costs per additionally gained life year is difficult: The benefit of prevention is shifted into the distant future. The influence of an untreated subclinical thyroid disease on life expectancy can only be demonstrated by a long-term follow-up and by epidemiological databases. Iodine supplementation and programs for the prevention of tobacco smoking (primary prevention) are very cost-effective. Smoking increases the risk both of multinodular goiter and of Graves' disease. Screening programs (secondary prevention) are discussed for the laboratory parameters thyrotropin (TSH), calcium and calcitonin. TSH testing seems to be very cost-effective for epidemiological considerations in a certain lifespan (newborn, pregnancy, postpartal), older persons, hospitalisation due to acute diseases and in persons with previously elevated TPO-antibodies for TSH-values >2 mU/l, but dedicated cost-effectiveness analyses are lacking. On the other hand, the cost-effectiveness of a routine TSH testing beyond the age of 35 years has been shown by a high-quality decision analysis. Therapeutic strategies (tertiary prevention) aim at the avoidance of complications (atrial fibrillation, myocardial infarction, death for cardiac reasons) and of iatrogenic complications. Examples of a tertiary prevention are: firstly the definitive therapy of Graves' disease in patients who have on increased risk of relapse after antithyroid drugs (ATD), secondly the radioiodine therapy for subclinical hyperthyroidism and the radioiodine therapy of large goiters in older patients or in patients suffering from a relevant comorbidity. Cost-effectiveness analyses for different therapeutic strategies of Graves' disease were published using a lifelong time-horizon. The ablative radioiodine dose-regime is cost-effective as a fist line therapy if the risk of relapse after ATD exceeds 60%. (orig

To determine adherence patterns for thiazide diuretics, alkali citrate therapy, and allopurinol, collectively referred to as preventive pharmacological therapy (PPT), among patients with kidney stones. Using medical claims data, we identified adults diagnosed with kidney stones between 2002 and 2006. Through National Drug Codes, we determined those with one or more prescription fills for a PPT agent. We measured adherence to PPT (as determined by the proportion of days covered formula) within the first 6 months of starting therapy and performed multivariate analysis to evaluate patient factors associated with PPT adherence. Among 7980 adults with kidney stones who were prescribed PPT, less than one third (30.2%) were adherent to their regimen (indicated by proportion of days covered ≥ 80%). Among those on monotherapy, rates of adherence differed by the type of PPT agent prescribed: 42.5% for thiazides, 40.0% for allopurinol, and 13.4% for citrate therapy. Factors that were independently associated with lower odds of PPT adherence included combination therapy receipt, female gender, less generous health insurance, and residence in the South or Northeast. In contrast, older patients and those with salaried employment had a higher probability of PPT adherence. Adherence to PPT is low. These findings help providers identify patients where PPT adherence will be problematic. Moreover, they suggest possible targets for quality improvement efforts in the secondary prevention of kidney stones. Copyright © 2016 Elsevier Inc. All rights reserved.

Many modalities of cancer therapy induce mechanisms of treatment resistance and escape pathways during chronic treatments, including photodynamic therapy (PDT). It is conceivable that resistance induced by one treatment might be overcome by another treatment. Emerging evidence suggests that the unique mechanisms of tumor cell and microenvironment damage produced by PDT could be utilized to overcome cancer drug resistance, to mitigate the compensatory induction of survival pathways and even to re-sensitize resistant cells to standard therapies. Approaches that capture the unique features of PDT, therefore, offer promising factors for increasing the efficacy of a broad range of therapeutic modalities. Here, we highlight key preclinical findings utilizing PDT to overcome classical drug resistance or escape pathways and thus enhance the efficacy of many pharmaceuticals, possibly explaining the clinical observations of the PDT response to otherwise treatment-resistant diseases. With the development of nanotechnology, it is possible that light activation may be used not only to damage and sensitize tumors but also to enable controlled drug release to inhibit escape pathways that may lead to resistance or cell proliferation.

The present study compares the efficacy of 915- and 2450-MHz contrast-enhanced ultrasound (CEUS)-guided percutaneous microwave coagulation with that of CEUS-guided thrombin injection for the treatment of trauma-induced spleen hemorrhage. In a canine splenic artery hemorrhage model with two levels of arterial diameter (A, microwaves and drug injection. Therapy efficacy was measured by comparing bleeding rate, hemostatic time, bleeding index, bleeding volume, and pathology. The most efficient technique was CEUS-guided 915-MHz percutaneous microwave coagulation therapy in terms of action time and total blood loss. The success rate of the 915-MHz microwave group was higher than that of the 2450-MHz microwave and the drug injection groups (except A level, P microwave group than those in the 2450-MHz microwave and drug injection groups (P microwave group, but pathologic changes of light injury could be seen in the other groups. The present study provides evidence that microwave coagulation therapy is more efficient than thrombin injection for the treatment of splenic hemorrhage. Furthermore, treatment with 915-MHz microwaves stops bleeding more rapidly and generates a wider cauterization zone than does treatment with 2450-MHz microwaves. Copyright © 2014 Elsevier Inc.

Formulation scientists are recognizing nanoengineered drug delivery systems as an effective strategy to overcome limitations associated with antibiotic drug therapy. Antibiotics encapsulated into nanodelivery systems will contribute to improved management of patients with various infectious diseases and to overcoming the serious global burden of antibiotic resistance. An extensive review of several antibiotic-loaded nanocarriers that have been formulated to target drugs to infectious sites, achieve controlled drug release profiles, and address formulation challenges, such as low-drug entrapment efficiencies, poor solubility and stability is presented in this paper. The physicochemical properties and the in vitro/in vivo performances of various antibiotic-loaded delivery systems, such as polymeric nanoparticles, micelles, dendrimers, liposomes, solid lipid nanoparticles, lipid-polymer hybrid nanoparticles, nanohybirds, nanofibers/scaffolds, nanosheets, nanoplexes, and nanotubes/horn/rods and nanoemulsions, are highlighted and evaluated. Future studies that will be essential to optimize formulation and commercialization of these antibiotic-loaded nanosystems are also identified. The review presented emphasizes the significant formulation progress achieved and potential that novel nanoengineered antibiotic drug delivery systems have for enhancing the treatment of patients with a range of infections. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.
Full Text Available Nanoparticles have increasingly been used for a variety of applications, most notably for the delivery of therapeutic and diagnostic agents. A large number of nanoparticle drug delivery systems have been developed for cancer treatment and various materials have been explored as drug delivery agents to improve the therapeutic efficacy and safety of anticancer drugs. Natural biomolecules such as proteins are an attractive alternative to synthetic polymers which are commonly used in drug formulations because of their safety. In general, protein nanoparticles offer a number of advantages including biocompatibility and biodegradability. They can be prepared under mild conditions without the use of toxic chemicals or organic solvents. Moreover, due to their defined primary structure, protein-based nanoparticles offer various possibilities for surface modifications including covalent attachment of drugs and targeting ligands. In this paper, we review the most significant advancements in protein nanoparticle technology and their use in drug delivery arena. We then examine the various sources of protein materials that have been used successfully for the construction of protein nanoparticles as well as their methods of preparation. Finally, we discuss the applications of protein nanoparticles in cancer therapy.

Spondyloarthritis represents a heterogeneous group of articular inflammatory diseases that share common genetic, clinical and radiological features. The therapy target of spondyloarthritis relies mainly in improving patients' quality of life, controlling articular inflammation, preventing the structural joints damage and preserving the functional abilities, autonomy and social participation of patients. Among these, traditional disease-modifying antirheumatic drugs have been demonstrated to be effective in the management of peripheral arthritis; moreover, in the last decade, biological therapies have improved the approach to spondyloarthritis. In patients with axial spondyloarthritis, tumor necrosis factor α inhibitors are currently the only effective therapy in patients for whom conventional therapy with nonsteroidal anti-inflammatory drugs has failed. The aim of this review is to summarize the current experience and evidence about the pharmacological approach in spondyloarthritis patients.

Factors predisposing hormone-dependent tissues to the development of tumors coincide, at least partly, with hormonal-metabolic promoters (like insulin resistance, glucose intolerance, visceral obesity, etc.) of other main non-communicable diseases. This important knowledge poses the question of whether the same approach which is applied for prevention/treatment of a metabolic syndrome and the associated endocrine disorders might also be used in preventive and therapeutic oncology. Whereas an answer to this question remains controversial and is based mainly on experimental evidence, there is accumulating clinical data suggesting a practical significance of such a strategy, even though it is not to be considered as directly cytostatic. Among the many drugs under discussion, three groups of medicines (statins, antidiabetic biguanides, and thiazolidinediones) are the most attractive. The concept of metabolic rehabilitation is proposed and used practically in an adjuvant setting for the correction of the above-mentioned endocrine-metabolic disorders commonly found in cancer patients. The current use and aim of this approach is to improve the survival of patients and limit cancer progression. Nonetheless, it also appears potentially useful as a neoadjuvant therapy as well as a prophylactic treatment earlier in life for specific groups of people with hormone-associated enhanced oncological risk. It seems possible that certain hypolipidemic and antidiabetic medicines with pleiotropic effects might be combined with traditional antisteroid prevention/therapeutic approaches in routine clinical situations as well as for overcoming resistance to standard cancer hormonal therapies including receptor-negative cases. Characteristic at the end of the 20th and at the beginning of the 21st century is an epidemic of diabetes and obesity, which might further increase the incidence of certain cancers. This makes it timely to apply hypolipidemic and antidiabetic drugs (in combination

Urinary tract infections (UTI) are among the most common bacterial infections in humans, affecting millions of people every year. UTI cause significant morbidity in women throughout their lifespan, in infant boys, in older men, in individuals with underlying urinary tract abnormalities, and in those that require long-term urethral catheterization, such as patients with spinal cord injuries or incapacitated individuals living in nursing homes. Serious sequelae include frequent recurrences, pyelonephritis with sepsis, renal damage in young children, pre-term birth, and complications of frequent antimicrobial use including high-level antibiotic resistance and Clostridium difficile colitis. Uropathogenic E. coli (UPEC) cause the vast majority of UTI, but less common pathogens such as Enterococcus faecalis and other enterococci frequently take advantage of an abnormal or catheterized urinary tract to cause opportunistic infections. While antibiotic therapy has historically been very successful in controlling UTI, the high rate of recurrence remains a major problem, and many individuals suffer from chronically recurring UTI, requiring long-term prophylactic antibiotic regimens to prevent recurrent UTI. Furthermore, the global emergence of multi-drug resistant UPEC in the past ten years spotlights the need for alternative therapeutic and preventative strategies to combat UTI, including anti-infective drug therapies and vaccines. In this chapter, we review recent advances in the field of UTI pathogenesis, with an emphasis on the identification of promising drug and vaccine targets. We then discuss the development of new UTI drugs and vaccines, highlighting the challenges these approaches face and the need for a greater understanding of urinary tract mucosal immunity.

Full Text Available Background: Long-acting therapy in laboratory animals offers advantages over the current practice of 2-3 daily drug injections. Yet little is known about the disintegration of biodegradable drug implants in rodents. Objective: Compare bioavailability of buprenorphine with the biodegradation of lipid-encapsulated subcutaneous drug pellets. Methods: Pharmacokinetic and histopathology studies were conducted in BALB/c female mice implanted with cholesterol-buprenorphine drug pellets. Results: Drug levels are below the level of detection (0.5 ng/mL plasma within 4-5 days of implant. However, necroscopy revealed that interstitial tissues begin to seal implants within a week. Visual inspection of the implant site revealed no evidence of inflammation or edema associated with the cholesterol-drug residue. Chemical analyses demonstrated that the residues contained 10-13% of the initial opiate dose for at least two weeks post implant. Discussion: The results demonstrate that biodegradable scaffolds can become sequestered in the subcutaneous space. Conclusion: Drug implants can retain significant and unintended reservoirs of drugs.

This article reviews the latest developments in understanding the pathogenesis, detection and treatment of small intestinal damage and bleeding caused by nonsteroidal anti-inflammatory drugs (NSAIDs). With improvements in the detection of NSAID-induced damage in the small intestine, it is now clear that this injury and the associated bleeding occurs more frequently than that occurring in the stomach and duodenum, and can also be regarded as more dangerous. However, there are no proven-effective therapies for NSAID-enteropathy, and detection remains a challenge, particularly because of the poor correlation between tissue injury and symptoms. Moreover, recent studies suggest that commonly used drugs for protecting the upper gastrointestinal tract (i.e., proton pump inhibitors) can significantly worsen NSAID-induced damage in the small intestine. The pathogenesis of NSAID-enteropathy is complex, but studies in animal models are shedding light on the key factors that contribute to ulceration and bleeding, and are providing clues to the development of effective therapies and prevention strategies. Novel NSAIDs that do not cause small intestinal damage in animal models offer hope for a solution to this serious adverse effect of one of the most widely used classes of drugs. PMID:23569332

Injection drug use remains a primary driver of HIV and HCV-related harms globally. However, there is a gap in efforts to prevent individuals from transitioning into injecting. People who inject drugs (PWID) play a key role in the transition of others into injecting, and while behavioral interventions have been developed to address this phenomenon, socio-structural approaches remain unexplored. To that end, we hypothesize that certain interventions designed to reduce injecting-related risk behaviors may also reduce the risk that PWID expose and introduce others into injecting. Identifying the preventive potential of existing interventions will inform broader efforts to prevent injecting and related harms. The Preventing Injecting by Modifying Existing Responses (PRIMER) study is a multi-country mixed methods study with an aim to investigate whether specific interventions (e.g., opioid substitution therapy, supervised injection facilities, stable housing, incarceration environments) and related factors (e.g., public injecting and gender) influence the likelihood that PWID initiate others into injecting. This study will (1) investigate the PWID participation in injection initiation; (2) identify factors influencing the risk that PWID expose others to or facilitate injection initiation; (3) describe drug scene roles that increase the risk of PWID facilitating injection initiation; and (4) evaluate the impact of structural, social, or biomedical interventions on the risk that PWID facilitate injection initiation. It does so by pooling observational data from cohort studies of PWID in six cities: Vancouver, Canada; San Diego, USA; Tijuana, Mexico; Paris, Marseille, and Bordeaux, France. Team members are conducting a prospective, multi-site study of PWID (n = 3050) in North America and France that includes quantitative and qualitative data collection through four separate cohort studies of PWID (San Diego, STAHR II; Tijuana, El Cuete IV; Vancouver, V-DUS; Bordeaux

Tardive dyskinesia (TD) is a movement disorder of tongue, jawbone, trunk and/or limbs that may appear after a prolonged use of dopamine receptor blocking agents (after 3 months of treatment or after 1 month for patients over 60), and that are present during at least four consecutive weeks. TD is a frequent side effect of both classical neuroleptics and new generation antipsychotic drugs. The prevalence of iatrogenic TD is between 24 and 32 % after treatment with classical neuroleptics and about 13 % after treatment with a new generation antipsychotic. This paper presents an updated literature review of data on diagnosis, prevention and treatment of TD. We conducted a review of literature using the Medline Browser tool, screening studies from 1950 to 2013 in English or French with keywords « tardive dyskinesia », « tardive dystonia », and « abnormal movements caused by antipsychotic drugs ». We first describe and define semeiological features of TD: dystonia, tremor, myoclonus, acathisie, chorea, ballism and athetosia. Secondarily, we resume the main differential diagnoses to exclude when confronted with this kind of movement disorders. Differential diagnoses for dyskinesia can be classified between primary (Parkinson and Huntington diseases) and secondary (Wilson disease, intoxication, metabolic abnormality, cerebrovascular accident) abnormal movements. Psychogenic TD can be evocated if previous pathologies are excluded in case of atypical clinical presentation. We detail the risk factors for TD. Endogenous risk factors are related to the patient's age, underlying psychiatric disease (bipolar disorder or Alzheimer dementia), addiction to alcohol or cocaine, female gender, or neurodevelopmental vulnerability. Iatrogenic risk factors are high doses of antipsychotics, long or intermittent administration, and particular pharmaceutical classes or associations of antipsychotics. As a comprehensive tool, we review the main physiopathological hypotheses to

Full Text Available The purpose of this article was to assess the effectiveness of ozone therapy in the management and prevention of caries, reviewing clinical and in vitro studies. Ozone has proven to be effective against gram-negative and gram-positive bacteria, viruses, and fungi. In dentistry, most of the published articles are based on ozone's antimicrobial effects and the treatment of caries. Most of the clinical studies reported ozone to be a promising alternative to conventional methods for caries management. However, a few studies have shown ozone to be insufficient for preventing caries and reducing microorganisms in open occlusal carious lesions. Ozone might be a useful tool to reduce and control oral infectious microorganisms in dental plaque and dental cavity. However, the results of in vitro studies are controversial; while some researchers reported that ozone therapy had a minimal or no effect on the viability of microorganisms, others suggested ozone to be highly effective in killing both gram-positive and gram-negative oral microorganisms. Therefore, more evidence is required before ozone can be accepted as an alternative to present methods for the management and prevention of caries.

Good medication adherence is the cornerstone of therapeutic success. Alzheimer's disease (AD) is the most common type of dementia and most patients are old and on multiple drugs, and good compliance therefore is even more important in this population. Dementia of Alzheimer's type (DAT) at present is yet to find a cure. Anticholinesterases and N-methyl-D-aspartate blockers are specific anti-AD therapies available. Hypertension, diabetes, and dyslipidemia can contribute to cognitive worsening. Keeping hypertension, diabetes, and dyslipidemia in control can therefore possibly prevent further cognitive decline. Patients with subjective memory complaints (n = 75) were chosen randomly. Upon thorough neurological diagnostic work up for dementia, those with mild cognitive impairment/questionable dementia (Clinical Dementia Rating = 0.5) or those with AD were recruited in this study (n = 67). Those with hypertension, diabetes, and deranged lipid profile were further interviewed if they were able to take medicines regularly or not. An attempt was made to know causes of non-compliance. Forty-one percent of patients were not taking the drugs that have potential to prevent cardiovascular complications or ability to slow down cognitive decline in AD on regular basis. The lack of awareness, ignorance, medicines being "too expensive," and the pressure of taking medicines regularly were cited as the reasons for non-compliance. Being illiterate and having low education contributed majorly to poor compliance in this study. Compliance to drugs that have potential or real ability to slow down cognitive decline is low in elderly people with DAT.

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed for the treatment of pain, inflamation and fever. They are usually well tolerated in healthy persons, but in patients with risk factors (advanced age, renal impairment, heart failure, liver disease, concurrent medications with antihypertensive drugs), NSAIDs can induce serious renal adverse effects. They include sodium and water retention with edema, worsening of heart failure, hypertension, hyponatremia, hyperkalemia, acute kidney injury, chronic kidney disease, renal papillary necrosis and acute interstitial nephritis. The majority of these adverse effects are due to the inhibition of prostaglandins synthesis and they are dose and duration-dependent. Acute forms of kidney injuries are transient and often reversible upon drug withdrawal. Chronic use of NSAIDs in some patients may result in chronic kidney disease. It is recommended that patients at risk should have preventative strategies in place, including the use of the "lowest effective dose" of NSAID for the "shortest possible time" and monitoring renal function, fluid retention and electrolyte abnormalities. Patients who are taking antihypertensive medications should be monitored for high blood pressure and the doses of antihypertensive medications should be adjusted if needed. In general, the combination of NSAIDs and angiotensin inhibitors should be avoided. Some other preventive measures are dietary salt restriction, use of topical NSAIDs/non-pharmacological therapies and use of calcium channel blockers for treating hypertension.

Hepatocellular carcinoma (HCC) is one of the deadliest cancers in the world and is associated with a high risk of recurrence. The development of a wide range of new therapies is therefore essential. In this study, from the perspective of supportive therapy for the prevention of HCC recurrence and preservation of liver function in HCC patients, we surveyed a variety of different therapeutic agents. We show that branched chain amino acids (BCAA) supplementation and late evening snack with BCAA, strategies that address issues of protein-energy malnutrition, are important for liver cirrhotic patients with HCC. For chemoprevention of HCC recurrence, we show that viral control after radical treatment is important. We also reviewed the therapeutic potential of antiviral drugs, sorafenib, peretinoin, iron chelators. Sorafenib is a kinase inhibitor and a standard therapy in the treatment of advanced HCC. Peretinoin is a vitamin A-like molecule that targets the retinoid nuclear receptor to induce apoptosis and inhibit tumor growth in HCC cells. Iron chelators, such as deferoxamine and deferasirox, act to prevent cancer cell growth. These chelators may have potential as combination therapies in conjunction with peretinoin. Finally, we review the potential inhibitory effect of bone marrow cells on hepatocarcinogenesis. PMID:27621572

Full Text Available Introduction: Mast cells are among the first cells to get in-volved in periodontal inflammation. Their numbers have been shown to be in-creased in cases of gingivitis and periodontal disease. The hypothesis: Since mast cell stabilizers like sodium cromogly-cate (SCG and nedocromil sodium (NS have been used in the prophylaxis of bronchial asthma without any significant adverse effects and also the fact that drugs like SCG show significant anti-inflammatory activities, it would be logical to use mast cell stabilizers as host modulating drugs for the treatment and prevention of peri-odontal disease. Evaluation of the hypothesis: Safety and efficacy of both SCG and NS are well documented. So, it will be systemically safe to use in humans. However, oral administration SCG or delivery of the drug by means local irrigation will not be very useful because SCG may not be secreted in the gingival crevicular fluid (GCF(as in the case of oral administraion or the drug may get washed out from periodontal pocket due to the constant flow of GCF(as in the case of irrigation. A local or targeted drug delivery of mast cell stabilizers can be used in patients with periodontal disease. Role of mast cells in periodontal disease has been dealt in-depth in many studies and articles. However, limited amount of research has been done on using mast cell stabilizers in the prevention and control of periodontal diseases. More studies are needed to study the efficacy and effective-ness of mast cell stabilizers as an adjunct to phase I therapy in the control of periodontal disease.
Many peri- and postmenopausal women suffer from a reduced quality of life due to menopausal symptoms and preventable diseases. The importance of cardiovascular disease in women must be emphasized, as it is the leading cause of mortality and morbidity in women. It is well known that female hormones...... contribute to the later onset of cardiovascular disease in women. The effect of estrogens has for decades been understood from observational studies of postmenopausal women treated with hormone replacement therapy (HRT). Later, treatment with HRT was disregarded due to the fear of side...

Stroke is the main cause of disability in high-income countries and ranks second as a cause of death worldwide. Infections occur frequently after stroke and may adversely affect outcome. Preventive antibiotic therapy in the acute phase of stroke may reduce the incidence of infections and improve outcome. In the previous version of this Cochrane Review, published in 2012, we found that antibiotics did reduce the risk of infection but did not reduce the number of dependent or deceased patients. However, included studies were small and heterogeneous. In 2015, two large clinical trials were published, warranting an update of this Review. To assess the effectiveness and safety of preventive antibiotic therapy in people with ischaemic or haemorrhagic stroke. We wished to determine whether preventive antibiotic therapy in people with acute stroke:• reduces the risk of a poor functional outcome (dependency and/or death) at follow-up;• reduces the occurrence of infections in the acute phase of stroke;• reduces the occurrence of elevated body temperature (temperature ≥ 38° C) in the acute phase of stroke;• reduces length of hospital stay; or• leads to an increased rate of serious adverse events, such as anaphylactic shock, skin rash, or colonisation with antibiotic-resistant micro-organisms. We searched the Cochrane Stroke Group Trials Register (25 June 2017); the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 5; 25 June 2017) in the Cochrane Library; MEDLINE Ovid (1950 to 11 May 2017), and Embase Ovid (1980 to 11 May 2017). In an effort to identify further published, unpublished, and ongoing trials, we searched trials and research registers, scanned reference lists, and contacted trial authors, colleagues, and researchers in the field. Randomised controlled trials (RCTs) of preventive antibiotic therapy versus control (placebo or open control) in people with acute ischaemic or haemorrhagic stroke.

Fracture prevention is one of the public health priorities worldwide. Estrogen deficiency is the major factor in the pathogenesis of postmenopausal osteoporosis, the most common metabolic bone disease. Different effective treatments for osteoporosis are available. Hormone replacement therapy (HRT) at different doses rapidly normalizes turnover, preserves bone mineral density (BMD) at all skeletal sites, leading to a significant, reduction in vertebral and non-vertebral fractures. Tibolone, a selective tissue estrogenic activity regulator (STEAR), is effective in the treatment of vasomotor symptoms, vaginal atrophy and prevention/treatment of osteoporosis with a clinical efficacy similar to that of conventional HRT. Selective estrogen receptor modulators (SERMs) such as raloxifene and bazedoxifene reduce turnover and maintain or increase vertebral and femoral BMD and reduce the risk of osteoporotic fractures. The combination of bazedoxifene and conjugated estrogens, defined as tissue selective estrogen complex (TSEC), is able to reduce climacteric symptoms, reduce bone turnover and preserve BMD. In conclusion, osteoporosis prevention can actually be considered as a major additional benefit in climacteric women who use HRT for treatment of climacteric symptoms. The use of a standard dose of HRT for osteoporosis prevention is based on biology, epidemiology, animal and preclinical data, observational studies and randomized, clinical trials. The antifracture effect of a lower dose HRT or TSEC is supported by the data on BMD and turnover, with compelling scientific evidence. PMID:26327857

Vibrio cholerae is the causative agent of the diarrheal disease cholera. Although antibiotic therapy shortens the duration of diarrhea, excessive use has contributed to the emergence of antibiotic resistance in V. cholerae. Mobile genetic elements have been shown to be largely responsible for the shift of drug resistance genes in bacteria, including some V. cholerae strains. Quorum sensing communication systems are used for interaction among bacteria and for sensing environmental signals. Sequence analysis of the ctxB gene of toxigenic V. cholerae strains demonstrated its presence in multiple cholera toxin genotypes. Moreover, bacteriophage that lyse the bacterium have been reported to modulate epidemics by decreasing the required infectious dose of the bacterium. In this article, we will briefly discuss the disease, its clinical manifestation, antimicrobial resistance and the novel approaches to locate drug targets to treat cholera.

Duchenne muscular dystrophy (DMD) is a genetic, lethal, muscle disorder caused by the loss of the muscle protein, dystrophin, leading to progressive loss of muscle fibers and muscle weakness. Drug discovery efforts targeting DMD have used two main approaches: (1) the restoration of dystrophin expression or the expression of a compensatory protein, and (2) the mitigation of downstream pathological mechanisms, including dysregulated calcium homeostasis, oxidative stress, inflammation, fibrosis, and muscle ischemia. The aim of this review is to introduce the disease, its pathophysiology, and the available research tools to a drug discovery audience. This review will also detail the most promising therapies that are currently being tested in clinical trials or in advanced preclinical models. © 2015 Society for Laboratory Automation and Screening.

Systemic corticosteroids are the mainstay of therapy for noninfectious posterior uveitis; however, various systemic side effects can occur. Intravitreal medication achieves a therapeutic level in the vitreous while minimizing systemic complications and is thus used as an exciting alternative. Corticosteroids, antivascular endothelial growth factors, immunomodulators such as methotrexate and sirolimus, and nonsteroidal anti-inflammatory drugs are currently available for intravitreal therapy. This article reviews the existing literature for efficacy and safety of these various options for intravitreal drug therapy for the management of noninfectious uveitis (mainly intermediate, posterior, and panuveitis.

Conclusion: Our findings suggest that pharmacists-initiated interventions can ameliorate DTPs in patients receiving ART given the high intervention acceptance rate recorded. The implication of this finding is that pharmacists with requisite training in HIV pharmacotherapy are an excellent resource in detecting and minimizing the effect of antiretroviral drug-related errors.

Full Text Available Cutaneous adverse drug reactions are commonly seen in patients with anticancer drug treatment. Anticancer drugs, including chemotherapy, target therapy, and recent immunotherapy causing skin reactions ranging from mild skin rash to life-threatening severe cutaneous adverse reactions (SCARs, such as Stevens-Johnson syndrome (SJS and toxic epidermal necrosis (TEN with increase morbidity and mortality while they are receiving cancer treatments, have been proposed to be a result of direct skin toxicity or drug hypersensitivity reactions (these are proposed mechanism, not definite. Differentiating SCARs from other more commonly seen reactions with a better outcome help prevent discontinuation of therapy and inappropriate use of systemic immunosuppressants for presumable allergic reactions, of which will affect the clinical outcome. In this article, we have reviewed published articles from 1950 to August 2017 for SJS/TEN associated with anticancer drugs, including chemotherapy, targeted therapy, and immunotherapy. We aimed to provide an overview of SJS/TEN associated with anticancer drugs to increase clinician recognition and accelerate future studies on the pathomechanism and managements.

This study was designed to explore Category 3 and 4 controlled drug users' perceptions of participating in health-prevention lectures. A phenomenological approach was used. Twelve participants were interviewed after completing the lectures. Findings revealed five themes (1) mixed emotions; (2) self-development; (3) finding the lectures lacked practicality and relevance; (4) highlighting three stages for discontinuing drug-usage; and, (5) suggesting tips for the advancement of lectures. These findings could be used as a map to help health professionals understand drug users' perceptions of attending health prevention lectures and provide insight into how young people might stop using drugs.

Due diligence in the process of provision of healthcare services refers, among other elements, to the application of pharmacological therapy at a time which offers the greatest chance for a successful outcome of treatment, i.e. for achieving the optimum expected effect understood as an improvement in the patient's health, reduction of health risks or elimination of the disease. However, due diligence may also refer to actions aimed at ensuring that neither the patient nor the healthcare payer is required to incur unreasonable costs in the process of treatment. The validity of that statement stems not only from normative acts but also from ethical standards laid down in the Medical Code of Ethics (Article 57 section 2). It often happens that the provision of optimal treatment calls for deviations from the formal provisions included in Summary Product Characteristics (SPCs), and the application of drugs that are bioequivalent to reference drugs, which translates into a significant reduction of costs. The present study addresses the problem of acceptability of a specific form of drug substitution consisting in the replacement of a reference drug with a generic drug. Also explored are legal aspects associated with the possibility of therapy based on "off-label use". The study reviews normative acts existing in the Polish and EU legislation. It also provides a clear definition of orphan drug, which has made it possible to make a distinction and investigate mutual relations between the concepts of brand-name (reference) drug, orphan drug and generic drug.

Hyperhidrosis affects 4.8% of the U.S. population and has been underestimated by physicians for long time despite considerable interference with quality of life. Many patients suffer from primary (idiopathic) hyperhidrosis which results from over-activity of sympathetic nerves and is restricted to specific body areas, mostly the axillae, palms, soles, or head. Secondary hyperhidrosis is caused by an underlying disease or the intake of medications and often involves large parts of the body. Numerous effective therapies with topical or systemic drugs and surgical options are available. Areas covered: Efficacy and safety data on aluminum salts, anticholinergic drugs for topical or systemic application, and on intradermal botulinum toxin injections used to treat hyperhidrosis are critically evaluated, including data from clinical trials with focus on possible side effects and long-term complications in dispute. Expert opinion: Hyperhidrosis often responds well to available therapies. Depending on the type of hyperhidrosis treatment should be topical/local or systemic. Most of the side effects are mild, transient and easily manageable. In case of systemic treatment with anticholinergics low dosing and up-titration of medication is necessary to avoid severe adverse effects. Concerns about the promotion of breast cancer and Alzheimer disease by topical aluminum salts are unsolved.

Migraine is a painful condition in which patients suffer from recurrent episodes of disabling pain, which could be very severe and can lead to grave psychological disturbances. There is no curative treatment for migraine, but there are various treatment modalities, though, with conflicting reports on their efficacy. This study was conducted to compare the effectiveness of electro acupuncture therapy and the conventional drug therapy on the psychological profile of migraneurs based on the assessment of quality of life and disability parameters. Migraneurs (n = 60) were recruited from the Psychiatry and Neurology OPD, Guru Tegh Bahadur Hospital, Delhi. Following a written consent, migraneurs were randomly allocated into 2 study groups--Group A received 10 sittings of electro acupuncture on selected acupuncture points over a period of 30 days, while for the same duration the Group D received a conventional drug therapy in the form of oral flunarizine 20 mg OD along with paracetamol 500 mg SOS. The patients were assessed twice, before and after completion of the treatment programme (30 days). The quality of life was assessed with WHOQOL BREF (WHO Quality of Life Biomedical Research and Education Foundation) questionnaire and the disability was assessed with MIDAS (Migraine Disability Assessment) questionnaire. Statistical analysis was performed using repeated measure's ANOVA with Tukey's test. Migraneurs were found to have lower quality of life and higher disability scores but following the treatment regimes, the 2 study groups showed a significant improvement in both the parameters studied. It was however observed, that the acupuncture group showed a better response and was thus found to be more effective as compared to the drug group (P = 0.005 to 0.000). We thus conclude that acupuncture is a better treatment option than the conventional drug therapy in not only relieving the pain of migraine but in also improving the psychological profile in migraneurs. Hence its

reduces placental parasitaemia by around 46% (RR 0.54, 95% CI 0.43 to 0.69; seven trials, 2830 participants, high quality evidence). Fewer trials evaluated spontaneous abortions, still births, perinatal deaths, or neonatal deaths, and these analyses were underpowered to detect clinically important differences. In multigravid women, chemoprevention has similar effects on antenatal parasitaemia (RR 0.38, 95% CI 0.28 to 0.50; three trials, 977 participants, high quality evidence)but there are too few trials to evaluate effects on other outcomes. In trials giving chemoprevention to all pregnant women irrespective of parity, the average effects of chemoprevention measured in all women indicated it may prevent severe anaemia (defined by authors, but at least < 8 g/L: RR 0.19, 95% CI 0.05 to 0.75; two trials, 1327 participants, low quality evidence), but consistent benefits have not been shown for other outcomes. In an analysis confined only to intermittent preventive therapy with SP, the estimates of effect and the quality of the evidence were similar. A summary of a single trial in Thailand of prophylaxis against P. vivax showed chloroquine prevented vivax infection (RR 0.01, 95% CI 0.00 to 0.20; one trial, 942 participants). Authors' conclusions Routine chemoprevention to prevent malaria and its consequences has been extensively tested in RCTs, with clinically important benefits on anaemia and parasitaemia in the mother, and on birthweight in infants. PLAIN LANGUAGE SUMMARY The effect of taking antimalarial drugs routinely to prevent malaria in pregnancy Pregnancy increases the risk of malaria and this is associated with poor health outcomes for both the mother and the infant, especially during the first or second pregnancy. For this reason, women are encouraged to try and prevent malaria infection during pregnancy by sleeping under mosquito bed-nets, and by taking drugs effective against malaria throughout pregnancy as chemoprevention. This Cochrane Review looked at all drug

Evidence clearly shows a chemopreventive effect for aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) on colorectal cancer and probably other cancer types; however, data on the risk-benefit profile for cancer prevention are insufficient and no definitive recommendations can be made. Aspirin has emerged as the most likely NSAID for use in chemoprevention because of its known cardiovascular benefit and available safety and efficacy data. Other traditional NSAIDs, particularly sulindac, and selective COX-2 inhibitors are now given to patients at high risk of colorectal cancer, although these drugs do not provide cardioprotection. More studies of aspirin and cancer prevention are needed to define the lowest effective dose, the age at which to initiate therapy, the optimum treatment duration, and the subpopulations for which the benefits of chemoprevention outweigh the risks of adverse side-effects. Although it might be possible to answer some of these questions with longer follow-up of existing clinical trials, randomised controlled trials with new study designs will be needed. Future projects should investigate the effects of aspirin treatment on multiple organ systems. Cancers of interest are colorectal, breast, prostate, lung, stomach, and oesophageal. The main side-effect of aspirin is peptic ulcers; therefore coadministration of aspirin with a proton-pump inhibitor is an attractive option and is under investigation in the AspECT trial.

Psychotherapy for sex offenders has only very recently started to develop in France. The French law on compulsory treatment for sex offenders was voted in 1998, and many mental health practitioners are not trained to treat such patients yet. In our ambulatory forensic consultation, sex offenders have been treated since 1992 and group psychotherapy has been offered to them since 1994. Our first therapeutic models were the North-American behavioural-cognitive therapy and Pithers' relapse prevention model. Behavioural-cognitive theory describes paedophilia as an acquired sexual preference maintained by positive reinforcement. Pithers (1990) considered that relapse only occurs in high-risk situations, and that high-risk situations always come after offence precursors. In North America, relapse prevention consists in helping paedophiles spot their high-risk situations and offence precursors, and enhance their skills to cope with such situations or to prevent them. Therapy programs were developed according to these models, aiming to help offenders develop such skills, ie empathy, social skills, cognitive restructuring, self-esteem, etc. Trying to apply these therapy programs in France, our team quickly realised that we would have to adapt them to French culture. On the one hand, behavioural-cognitive theory did not seem satisfactory enough in explaining paedophilic behaviour and paedophilic preference. On the other hand, behavioural-cognitive therapy made patients into children too much and increased resistance. Therapy based on programs seemed too rigid for French patients and therapists, and we often felt we were working on an issue that would have been much more accurate to work on a few sessions earlier, when this issue was spontaneously brought up by a patient. We believe change occurs all the more as issues are worked on at the right moment for the patient. Moreover, on a cultural point of view, we also realised the use of programs in psychotherapy was difficult to

Antiretroviral (ARV) drug use during pregnancy significantly reduces mother-to-child HIV transmission, delays disease progression in the women and reduces the risk of HIV transmission to HIV-serodiscordant partners. Pregnant women are susceptible to the same adverse reactions to ARVs as nonpregnant adults as well as to specific pregnancy-related reactions. In addition, we should consider adverse pregnancy outcomes and adverse reactions in children exposed to ARVs during intrauterine life. However, studies designed to assess the safety of ARV in pregnant women are rare, usually with few participants and short follow-up periods. In this review, we discuss studies reporting adverse reactions to ARV drugs, including maternal toxicity, adverse pregnancy outcomes and the consequences of exposure to ARV in infants. We included results of observational studies, both prospective and retrospective, as well as randomized clinical trials, systematic reviews and meta-analyses. The benefits of ARV use during pregnancy outweigh the risks of adverse reactions identified to date. More studies are needed to assess the adverse effects in the medium- and long term in children exposed to ARVs during pregnancy, as well as pregnant women using lifelong antiretroviral therapy and more recently available drugs.

We report the case of an HIV-positive Nigerian man on antiretroviral therapy (ART) with an undetectable viral load who presented with rigors, fever and back pain after returning to the UK from a three-week trip to Nigeria. Infection with Plasmodium falciparum malaria was confirmed and treatment with quinine commenced together with amoxicillin/clavulanic acid and clarithromycin for possible respiratory infection. At the time of admission the patient could not remember the names of his ART medications. After 24 hours his parasitaemia had increased from 1% to 2.5% and his clinical condition had deteriorated. At this point, his ART was identified as abacavir, lamivudine and nevirapine. The Liverpool HIV-drug interactions website was checked for drug interactions. It recommends caution in the co-administration of both clarithromycin and quinine with nevirapine. Quinine is metabolized by CYP34A and exposure is likely to be decreased by induction of these enzymes in patients taking nevirapine. Given the clinical deterioration the patient was switched to Malarone® (atovoquone/ proguanil) which has no clinically significant interactions with nevirapine. He responded to treatment and was discharged home after 48 hours. This case highlights the importance of knowing the potential drug interactions with ART and the importance of checking for such interactions when prescribing new medications.

To investigate the current status of studies on drug therapy for apnea of prematurity (AOP) in the past decade in China and abroad, and to describe the research trends in the field. CNKI and MEDLINE were searched with the key words "apnea of prematurity" and "treatment" for articles published in the past decade (January 2006 to December 2015). The articles were screened and the key words were extracted to establish the co-occurrence matrix. Ucinet 6.2 was used to plot the knowledge map. A total of 26 Chinese key words and 20 English key words were included. Those in the center of the co-existent knowledge map of Chinses keywords were "preterm infants", "apnea", "primary apnea", "naloxone" and "aminophylline"; while "apnea", "preterm infants" and "caffeine" located in the central place of the co-existent knowledge map of English keywords. Methylxanthines are still the major drugs for AOP; however, aminophylline is mainly used in China, while caffeine is mainly used in foreign countries. Other drugs such as naltrexone are also used in the clinical treatment of AOP.

The stimulation phase of electroconvulsive therapy (ECT) induces bradycardia. We evaluated the effect of this bradycardia on cerebral perfusion and oxygenation by administration of the anticholinergic drug glycopyrrolate (Glp). Cerebral perfusion was estimated by transcranial ultrasound...... in the middle cerebral artery reporting the mean flow velocity (middle cerebral artery [MCA] V(mean)), and cerebral oxygenation was determined by near-infrared spectroscopy of the frontal lobe. Before ECT, heart rate (HR) was 84 beats min(-1) (66-113; median and range) and decreased to 17 (7-85) beats min(-1...... and oxygenation normalized over approximately 3 minutes, whereas the electroencephalogram was unaffected by Glp. The results demonstrate that ECT is associated with hemodynamic effects severe enough to affect cerebral oxygenation and perfusion, and that these effects can be attenuated by Glp treatment....

A review of published data on the safety and efficacy of colchicine therapy for primary and secondary prevention of pericarditis is presented. Colchicine has been used effectively as an antiinflammatory agent for gout and has shown promise as a treatment for acute and recurrent pericarditis. Several small studies have indicated that colchicine can decrease pericarditis symptom persistence at 72 hours and pericarditis recurrence rates at 18 months compared with conventional therapy (corticosteroids and aspirin or ibuprofen). A review of pooled data from four prospective randomized trials concluded that colchicine is safe and efficacious for the management of acute and recurrent pericarditis, with the results indicating lower rates of the respective primary and secondary endpoints of recurrent disease and symptom persistence in colchicine-treated patients. A separate meta-analysis of five studies found a reduced risk of pericarditis with colchicine use, suggesting that the drug may have clinical utility in both primary and secondary prevention. The accumulated evidence suggests that treatment with colchicine in the context of pericarditis is safe and well tolerated, with gastrointestinal intolerance being the most common adverse event documented in the clinical trials to date. Based on a review of the literature, prevention of recurrent pericarditis with colchicine can be considered a safe and effective option, though some patients have experienced gastrointestinal intolerance. Due to evidence that corticosteroids may potentially exacerbate the risk of relapse, colchicine may be a safer and preferable option.

Children treated with chronic medications are at risk of drug-drug interactions (DDIs) when hospitalized with an acute illness and prescribed new medications. We aimed to measure the prevalence of potential DDIs (pDDIs) among hospitalized children treated with antiepileptic drugs (AEDs) and to evaluate the impact of computerized physician order entry (CPOE) on pDDIs. We analyzed a national sample of pediatric hospitalizations from 2005 to 2012 associated with administration of an AED and identified those prescribed a second medication with risk of a DDI. The prevalence of hospitalizations associated with a pDDI was calculated for each AED. We identified the drugs most commonly implicated in pDDIs and factors associated with pDDIs. Rates of pDDIs were measured in pre- and post-CPOE implementation periods. A pDDI was identified in 181 380 (41.7%) hospitalizations associated with the use of an AED, with 117 880 (27.1%) classified as severe pDDIs. AEDs most often implicated with a pDDI were phenobarbital, valproic acid, and phenytoin. Hospitalizations with pDDIs were associated with increased length of stay and a greater number of medications, ICU admissions, and operating room procedures. The implementation of CPOE did not result in a change in the rate of pDDIs (42.7% before versus 40.8% after; P = .48). Children treated with AEDs are at risk of pDDIs while hospitalized. The use of CPOE has not been associated with a significant decrease in the rate of pDDIs. Additional investigation to better define the impact of pDDIs and to advance development of clinical decision support within CPOE systems is warranted.

Guidelines recommend that patients with peripheral arterial disease should be medically treated to reduce the occurrence of serious cardiovascular events. Despite these recommendations, studies conducted in the early 2000s reported that medical therapies for secondary cardiovascular prevention are not given systematically to patients with peripheral arterial disease (PAD). We identified factors associated with the prescription of preventive therapies in patients with symptomatic PAD. Consecutive patients with symptomatic peripheral arterial disease (n = 362) treated between 2008 and 2010 in one tertiary care center (CHU de Quebec, Canada) were considered. Data were collected from the medical charts. The main outcome was the combined prescription of three therapies: 1) statins, 2) antiplatelets, 3) angiotensin-converting-enzyme inhibitors or angiotensin receptor blockers. The mean age was 70 years and 43% had a pre-existing coronary artery disease. Antiplatelet therapy was the most prescribed drug (83%). A total of 52% of the patients received the three combined therapies. Less than 10% of patients had a known contraindication to one class of medication. Having at least three cardiovascular risk factors (Odds Ratio (OR) = 4.51; 95% CI: 2.76-7.37) was the factor most strongly associated with the prescription of the combined therapies. Pre-existing coronary artery disease (OR = 2.28; 95% CI: 1.43-3.65) and history of peripheral vascular surgery (OR = 2.30; 95% CI: 1.37-3.86) were two factors independently associated with the prescription of the combined therapies. However, peripheral arterial disease patients with chronic critical limb ischemia were less likely to receive the combined therapies (OR = 0.53; 95% CI: 0.32-0.87) than those with claudication. The retrospective nature of this study, not allowing for an exhaustive report of the contraindication to medication prescription, is the main limitation. About half of the patients with peripheral arterial disease

Concomitant administration of multiple drugs can lead to unanticipated drug interactions and resultant adverse drug events with their associated costs. A more thorough understanding of the different cytochrome P450 isoenzymes and drug transporters has led to new methods to try to predict and prevent clinically relevant drug interactions. There is also an increased recognition of the need to identify the impact of pharmacogenetic polymorphisms on drug interactions. More stringent regulatory requirements have evolved for industry to classify cytochrome inhibitors and inducers, test the effect of drug interactions in the presence of polymorphic enzymes, and evaluate multiple potentially interacting drugs simultaneously. In clinical practice, drug alert software programs have been developed. This review discusses drug interaction mechanisms and strategies for screening and minimizing exposure to drug interactions. We also provide future perspectives for reducing the risk of clinically significant drug interactions. PMID:24745854

Platelet aggregation plays a key role in the development of major cardiovascular events (MACE) related to atherothrombosis. Since the appearance of coronary stenting, the importance of measuring and modulating platelet activity has considerably increased in the scientific literature during the last decade. Double antiplatelet therapy with aspirin and clopidogrel administrated to stent carriers has widely demonstrated its efficacy in the prevention of MACE compared with aspirin alone. These benefits are also present when a conservatory approach is chosen for acute coronary syndrome management. However, there are an important number of patients who develop MACE despite optimal dual antiplatelet therapy, most likely related to an incomplete platelet activity inhibition. Many studies suggest an important inter-individual variability in the response to the drugs, maybe related, at least in part, to the use of different assessment techniques of platelet aggregation. Other authors suggest an incomplete platelet inhibition as a possible explanation for the presence of MACE in patients under optimal antiplatelet therapy. Resistance to usual drugs has become a clinically relevant issue that requires an individual approach where new antiplatelet agents, such as prasugrel or ticagrelor, could play an important role as stated in current consensus documents.

Look-alike, sound-alike (LASA) drug names are a cause of medication errors with resulting patient harm and healthcare costs. This study assessed to which extent the use of the generic drug name, therapeutic class, health problem, and the U.S. Food and Drug Administration (FDA)-approved indications might be used to differentiate LASA drug pairs. We collected information about LASA drug pairs reported by the FDA to have look-alike sound-alike similarities. To assess potential for differentiating LASA drug pairs, we compared the following drug characteristics: generic name, therapeutic class, health problem, and FDA-approved indication. For the 33 FDA reported LASA drug pairs we identified a total of 432 FDA-approved indications. Using the generic name, therapeutic class, health problem and drug indication we were able to differentiate 8 (24.2%), 24 (72.7%), 25 (75.8%) and 26 (78.8%), respectively of the 33 LASA drug pairs. Using the generic name, therapeutic class, and health problem we were able to distinguish 31 (7.2%), 212 (49.1%), and 269 (62.3%), respectively of the 432 FDA-approved indications for the LASA drug pairs. Including the FDA-approved indication in the drug prescription may be used to differentiate LASA drug pairs and thus, prevent wrong drug medication errors.

Antimicrobial resistance of infectious agents is a growing problem worldwide. To prevent the continuing selection and spread of drug resistance, rational design of antibiotic treatment is needed, and the question of aggressive vs. moderate therapies is currently heatedly debated. Host immunity is an important, but often-overlooked factor in the clearance of drug-resistant infections. In this work, we compare aggressive and moderate antibiotic treatment, accounting for host immunity effects. We use mathematical modelling of within-host infection dynamics to study the interplay between pathogen-dependent host immune responses and antibiotic treatment. We compare classical (fixed dose and duration) and adaptive (coupled to pathogen load) treatment regimes, exploring systematically infection outcomes such as time to clearance, immunopathology, host immunization, and selection of resistant bacteria. Our analysis and simulations uncover effective treatment strategies that promote synergy between the host immune system and the antimicrobial drug in clearing infection. Both in classical and adaptive treatment, we quantify how treatment timing and the strength of the immune response determine the success of moderate therapies. We explain key parameters and dimensions, where an adaptive regime differs from classical treatment, bringing new insight into the ongoing debate of resistance management. Emphasizing the sensitivity of treatment outcomes to the balance between external antibiotic intervention and endogenous natural defenses, our study calls for more empirical attention to host immunity processes.

Full Text Available Alzheimer’s disease (AD is the most common cause of dementia associated with a progressive neurodegenerative disorder, with a prevalence of 44 million people throughout the world in 2015, and this figure is estimated to double by 2050. This disease is characterized by blood-brain barrier disruption, oxidative stress, mitochondrial impairment, neuroinflammation, and hypometabolism; it is related to amyloid-β peptide accumulation and tau hyperphosphorylation as well as a decrease in acetylcholine levels and a reduction of cerebral blood flow. Obesity is a major risk factor for AD, because it induces adipokine dysregulation, which consists of the release of the proinflammatory adipokines and decreased anti-inflammatory adipokines, among other processes. The pharmacological treatments for AD can be divided into two categories: symptomatic treatments such as acetylcholinesterase inhibitors and N-methyl-D-aspartate (NMDA receptor antagonists and etiology-based treatments such as secretase inhibitors, amyloid binders, and tau therapies. Strategies for prevention of AD through nonpharmacological treatments are associated with lifestyle interventions such as exercise, mental challenges, and socialization as well as caloric restriction and a healthy diet. AD is an important health issue on which all people should be informed so that prevention strategies that minimize the risk of its development may be implemented.

As a contact allergen causing type I and type IV hypersensitivity, mediated by reagins and allergen-specific T lymphocytes, expressed in a wide range of cutaneous eruptions following dermal or systemic exposure, nickel has acquired the distinction of being among the most frequent causes of hypersensitivity, occupationally as well as among the general population. In synoptic form the many effects that nickel has on the organism are presented, to provide a comprehensive picture of the aspects of that metal with many biologically noxious, but metallurgically indispensable characteristics. This paper reviews the epidemiology, the prognosis for occupational and non-occupational nickel allergic hypersensitivity (NAH), the many types of exposure and the resulting immune responses, immunotoxicity and rate of diffusion through the skin. Alternatives towards prevention and remediation, topical and systemic, for this pervasive and increasing form of morbidity resulting from multiple types of exposure are discussed. Merits and limitations of preventive measures in industry and private life are considered, as well as the effectiveness of topical and systemic therapy in treating NAH.

SYNOPSIS Cytomegalovirus (CMV) is the most common congenital viral infection in the developed world, with an overall birth prevalence of approximately 0.6%. Approximately 10% of congenitally infected infants have signs and symptoms of disease at birth, and these symptomatic infants have a high risk for demonstration of subsequent neurologic sequelae, including sensorineural hearing loss (SNHL), mental retardation, microcephaly, development delay, seizure disorders, and cerebral palsy. Antiviral therapy of children with symptomatic central nervous system (CNS) congenital CMV infection is effective at reducing the risk of long-term disabilities and should be offered to families with affected newborns. An effective pre-conceptual vaccine against CMV could, by preventing congenital infection, protect against long-term neurological sequelae and other disabilities. A variety of active and passive immunization strategies are in clinical trials and are likely to be licensed in the next few years. Until a vaccine is licensed, preventive strategies aimed at reducing transmission should be emphasized and public awareness increased, particularly among women of child-bearing age. PMID:23481104

Aim To assess prevention and reduction of trismus after surgically extracted impacted mandibular third molars with individual and combined therapy with corticosteroids and anti-inflammatory analgesics. Methods The research included 60 randomly selected patients (3 groups) attended to the Dental Oral Surgery of the Public Institution Healthcare Center Zenica during the period January-December 2008. Patients of both genders, 18-45 years of age, were presented without pain and other inflammatory symptoms at the time of surgery. According to a scheme established in the research protocol, two medications were administered orally: methylprednisolone(corticosteroid) 32 mg and meloxicam (non-steroidal anti-inflammatory analgesic, NSAID) 15 mg as a single drug, or a combination of both drugs. The level of trismus is assessed on the basis of differences of preoperative and postoperative values of interincisal spaces when fully opening the mouth on the second and the seventh post-operative day. The differences between groups of patients were evaluated by means of Tukey's HSD test. Results On the second and on the seventh post-operative day significantly better results were registered in the group that received only corticosteroids and in the group that received both, corticosteroids and NSAIDs compared to the group that received only NSAIDs. A tendency of trismus reduction was present in all patient groups for the second and seventh day after surgery. Conclusion Prevention and control of postoperative trismus after surgical extraction of impacted mandibular third molars with combined therapy is effective and superior comparing to individual therapy with meloxicam-or methylprednisolone alone.

Toll-like receptors (TLRs) are sentinel receptors of the host innate immune system that recognize conserved 'pathogen-associated molecular patterns' of invading microbes, including viruses. The activation of TLRs establishes antiviral innate immune responses and coordinates the development of long-lasting adaptive immunity in order to control viral pathogenesis. However, microbe-induced damage to host tissues may release 'danger-associated molecular patterns' that also activate TLRs, leading to an overexuberant inflammatory response and, ultimately, to tissue damage. Thus, TLRs have proven to be promising targets as therapeutics for the treatment of viral infections that result in inflammatory damage or as adjuvants in order to enhance the efficacy of vaccines. Here, we explore recent advances in TLR biology with a focus on novel drugs that target TLRs (agonists and antagonists) for antiviral therapy.

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease associated with significant morbidity and mortality. Current diagnostic criteria based on the presence of fixed airflow obstruction and symptoms do not integrate the complex pathological changes occurring within the lung and they do not define different airway inflammatory patterns. The current management of COPD is based on 'one size fits all' approach and does not take the importance of heterogeneity in COPD population into account. The available treatments aim to alleviate symptoms and reduce exacerbation frequency but do not alter the course of the disease. Recent advances in molecular biology have furthered our understanding of inflammatory pathways in pathogenesis of COPD and have led to development of targeted therapies (biologics and small molecules) based on predefined biomarkers. Herein we shall review the trials of biologics in COPD and potential future drug developments in the field.

This paper reviews recent results and work in progress from a longitudinal study of drug use etiologies and consequences. Early- and mid-adolescent drug use patterns, personality, and behavioral correlates were studied in a large sample of normal youth beginning in the mid-1970's. To determine the correlates and consequences of adolescent drug use, controlling for related tendencies such as lack of social conformity and deviant friendship networks, 654 youngsters were followed into young adulthood and their behaviors and lifestyles evaluated. Teenage drug use was found to disrupt many critical developmental tasks of adolescence and young adulthood. Tendencies to use many different drugs as an adolescent led in young adulthood to increased drug crime involvement, decreased college involvement, increased job instability, income, psychoticism, and stealing episodes. Intervention efforts should be directed not only towards decreasing drug use, but also towards improving personal maturity, social skills, and economic opportunities.
Full Text Available Injection drug users (IDUs continue to comprise a major risk group for HIV infection throughout the world and represent the focal population for HIV epidemics in Asia and Eastern Europe/Russia. HIV prevention programs have ranged from HIV testing and counseling, education, behavioral and network interventions, drug abuse treatment, bleach disinfection of needles, needle exchange and expanded syringe access, as well as reducing transition to injection and primary substance abuse prevention. With the advent of highly active antiretroviral therapy (HAART in 1996, dramatic clinical improvements have been seen. In addition, the treatment's impact on reducing HIV viral load (and therefore transmission by all routes provides a stronger rationale for an expansion of the focus on prevention to emphasize early identification and treatment of HIV infected individuals. However, treatment of IDUs has many challenges including adherence, resistance and relapse to high risk behaviors, all of which impact issues of access and ultimately effectiveness of potent antiretroviral treatment. A major current challenge in addressing the HIV epidemic revolves around an appropriate approach to HIV treatment for IDUs.

Under physiological conditions, a well-coordinated and balanced redox system exists to ensure that reactive oxygen species (ROS) are appropriately utilized to accomplish specific functions, such as signaling and protein regulation. The influence of ROS within malignant cells, whether for good or bad may depend on several factors, such as tumor and tissue type, disease stage, treatment strategy, as well as duration, specificity and levels of ROS. What then are the known roles of ROS in cancer? Firstly, ROS significantly impacts cancer phenotypes. Secondly, the oxidative ROS property responsible for killing cancer cells, also impact secondary signaling networks. Thirdly, a strong correlation exist between ROS and genetic instability which may promote mutations. Finally, emerging observations suggest a role for mitochondrial ROS in cancer drug resistance, with implications for therapy. The mitochondria is a key regulator of metabolic-redox (meta-redox) alterations within cancer cells. Like a double-edged sword, mitochondrial ROS perturbations in cancer therapy may be beneficial or detrimental. However, harnessing ROS-specific cancer-targeting benefits remain a major challenge.

Objective Examined the effects of Structural Ecosystems Therapy (SET), a family intervention for women living with HIV or AIDS, compared to a psycho-educational health group (HG) intervention, and reciprocal relationships between women and family members. Method Women (n = 126) and their family members (n = 269) were randomized to one of two conditions and assessed every 4 months for 12 months. Family functioning, drug use, and psychological distress was reported by multiple family members. Results Multilevel growth curve modeling showed a different family functioning trajectory between SET and HG, B = −0.05, SE = 0.02, p < .01. There was no intervention effect on the trajectory of family-level drug abstinence or psychological distress, but there was a significant difference in the trajectory of psychological distress after controlling for change in family functioning, B = −0.28, SE = 0.13, p < .05. There was an indirect effect from treatment through change in family functioning to change in psychological distress, B = 0.29, SE = 0.12, p < .05. With respect to reciprocal effects, family drug abstinence significantly predicted women’s abstinence 4 months later, B = 0.22, SE = 0.06, p < .001. Conclusion Findings demonstrated the interdependence of family members and the impact of family in relapse prevention and partially supported SET’s potential for maintaining family functioning and well-being for women living with HIV or AIDS in drug recovery.

Full Text Available A crucial part of the treatment of depression is the prevention of relapse and recurrence. Psychological interventions, especially cognitive behavior therapy (CBT are helpful in preventing relapse and recurrence in depression. The effectivity of four types of relapse prevention cognitive behavior therapy strategies will be addressed, i.e. acute prophylactic cognitive behavior therapy, continuation cognitive behavior therapy, sequential cognitive behavior therapy and cognitive behavior therapy in partial remission.Specific ingredients of three sequential cognitive behavior therapy programs (well-being cognitive therapy, preventive cognitive therapy, and mindfulness-based cognitive therapy will be discussed as applied after remission in patients that experienced previous depressive episodes. Sequential preventive cognitive behavior therapy after acute treatment may be an attractive alternative treatment for many patients who currently use antidepressants for years and years to prevent relapse and recurrence. This is an extremely challenging issue to research thoroughly. Future studies must rule out what intervention for whom is the best protection against relapse and recurrence in depression.

The aim of magnetic drug targeting (MDT) in cancer therapy is to concentrate chemotherapeutics to a tumor region while simultaneously the overall dose is reduced. This can be achieved with coated superparamagnetic nanoparticles bound to a chemotherapeutic agent. These particles are applied intra arterially close to the tumor region and focused to the tumor by a strong external magnetic field. The interaction of the particles with the field gradient leads to an accumulation in the region of interest (i.e. tumor). The particle enrichment and thereby the drug-load in the tumor during MDT has been proven by several analytical and imaging methods. Moreover, in pilot studies we investigated in an experimental in vivo tumor model the effectiveness of this approach. Complete tumor regressions without any negative side effects could be observed. - Research Highlights: →Iron oxide nanoparticles can be enriched in tumors by external magnetic fields. → Histology evidences the intravasation of particles enter the intracellular space. → Non-invasive imaging techniques can display the spatial arrangement of particles. → HPLC-analysis show outstanding drug enrichment in tumors after MDT.

The purpose of this study was to adapt and validate narrative scripts to be used for the video components of a culturally grounded drug prevention program for rural Native Hawaiian youth. Scripts to be used to film short video vignettes of drug-related problem situations were developed based on a foundation of pre-prevention research funded by the National Institute on Drug Abuse. Seventy-four middle- and high-school-aged youth in 15 focus groups adapted and validated the details of the scripts to make them more realistic. Specifically, youth participants affirmed the situations described in the scripts and suggested changes to details of the scripts to make them more culturally specific. Suggested changes to the scripts also reflected preferred drug resistance strategies described in prior research, and varied based on the type of drug offerer described in each script (i.e., peer/friend, parent, or cousin/sibling). Implications for culturally grounded drug prevention are discussed.

Young children living with a tuberculosis patient are at high risk of Mycobacterium tuberculosis infection and disease. WHO guidelines promote active screening and isoniazid (INH) preventive therapy (PT) for such children under 5 years, yet this well-established intervention is seldom used in endemic countries. We review the literature regarding barriers to implementation of PT and find that they are multifactorial, including difficulties in screening, poor adherence, fear of increasing INH resistance and poor acceptability among primary caregivers and healthcare workers. These barriers are largely resolvable, and proposed solutions such as the adoption of symptom-based screening and shorter drug regimens are discussed. Integrated multicomponent and site-specific solutions need to be developed and evaluated within a public health framework to overcome the policy-practice gap and provide functional PT programmes for children in endemic settings. © 2012 Blackwell Publishing Ltd.
Full Text Available Post-operative nausea and vomiting (PONV is a complication affecting between 20% and 40% of all surgery patients, with high-risk patients experiencing rates of up to 80%. Recent studies and publications have shed light on the uses of alternative treatment for PONV, through their modulation of endogenous opioid neuropeptides and neurokinin ligands. In addition to reducing PONV, hypnosis was reported to be useful in attenuating postoperative pain, anxiety, and contributing to hemodynamic stability. Music therapy has been utilized to deepen the sedation level and decrease patient anxiety, antiemetic and analgesic requirements, hospital length of stay, and fatigue. Isopropyl alcohol and peppermint oil aromatherapy have both been used to reduce postoperative nausea. With correct training in traditional Chinese healing techniques, acupuncture (APu at the P6 acupoint has also been shown to be useful in preventing early PONV, post-discharge nausea and vomiting, and alleviating of pain. Electro-acupuncture (EAPu, as with APu, provided analgesic and antiemetic effects through release of opioid neuropeptides and modulation. These non-pharmacological modalities of treatment contribute to an overall patient wellbeing, assisting in physical and emotional healing.

Prospective epidemiologic studies performed in large cohorts of men (total: 374,003 subjects) agree in which the risk of suffering Parkinson's disease diminishes progressively as the consumption of coffee and other caffeinated beverages increases. In the case of women (total: 345,184 subjects) the protective effect of caffeine is only observed in menopausal women which do not receive estrogen replacement therapy. Studies with models of acute parkinsonism in rodents have shown that caffeine reduces the loss of nigrostriatal dopaminergic neurons induced with the neurotoxins 6-hidroxidopamine and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, effect that seems to be mediated through blockade of A(2A) adenosine receptors. Recently, it was shown that male rats treated with moderate doses of caffeine (5 mg/kg/day) during six months, followed by a withdrawal period of at least two weeks, developed a greater resistance to the catalepsy induced with the dopaminergic antagonist haloperidol, which was possibly mediated by an increase of dopaminergic transmission in the corpus striatum. More studies are needed to demonstrate unequivocally that caffeine prevents the degeneration of dopaminergic neurons in animal models of moderate, chronic, and progressive parkinsonism, since it could lead to the discovery of more effective drugs for the prevention of aging-related degenerative diseases of the central nervous system.
Primary prevention in drug abuse has been, most of the time, reduced to its informational aspect. This paper points out some of the errors made in this field, both by contributing to the 'inflation' of the drug problem and by using scare tactics as preventive arguments. It invites consideration of drug addiction not as an isolated problem, but as one of the multiple results of an existential crisis, the author tries to show that in this field the emphasis of primary prevention should be on education.

This article explores the Advertising Council's first national drug abuse prevention campaign in the 1970s. Scholarship thus far has demonstrated the ways in which the issue of drug abuse represented a chief political strategy for President Nixon. Evidence from major trade press publications, congressional hearings, and an array of archival sources suggest that this campaign was also part of a public relations crusade on behalf of the advertising industry in response to public criticism of its role in abetting a culture of drug dependence. These institutional and political pressures helped shape drug abuse prevention in the 1970 s and for the decades that followed. Copyright © 2011 Informa Healthcare USA, Inc.

Single drug therapy that leads to the multidrug resistance of cancer cells and severe side-effect is a thing of the past. Combination therapies that affect multiple signaling pathways have been the focus of recent active research. Due to the successful development of prodrug-based nano-drug delivery systems (P-N-DDSs), their use has been extended to combination therapy as drug delivery platforms. In this review, we focus specifically on the P-N-DDSs in the field of combination therapy including the combinations of prodrugs with different chemotherapeutic agents, other therapeutic agents, nucleic acid or the combination of different types of therapy (e.g. chemotherapy and phototherapy). The relevant examples of prodrug-based nanoparticulate drug delivery strategy in combination cancer therapy from the recent literature are discussed to demonstrate the feasibilities of relevant technology.

In Germany there are currently approx. 200,000 homeless single people, and the trend is rising. As a result of the situation in which they find themselves, many of these persons are ill and in need of medical treatment. A study was performed in Munich/Germany, focussing on a medical practice providing care for the homeless, to investigate their illnesses and pharmacological therapy. The medical practice was located in a municipal shelter. Each year about 350 different destitute homeless men--about 15 per cent of all single homeless people in Munich--were cared for. The men, whose ages ranged from about 17 to 74 years were single and the majority lived in shelters, bed and breakfast accommodations, or shared apartments. About ten per cent lived on the street. For the study, 171 randomly selected medical records were analysed for the period of July 1994 to June 1995. The homeless men suffered principally from the following illnesses: psychiatric illnesses (36%), infectious and parasitic diseases (31%), skin diseases (30%), injuries (29%), diseases of the skeleton, of the muscles and of the connective tissues (28%), diseases of the respiratory organs (27%), cardiovascular diseases (24%), and diseases of the digestive organs (17%). Seventy-five per cent of the patients received drug treatment. In the case of 37% of the patients, wounds were treated and dressed in the medical practice itself. The most frequently prescribed drugs were: analgesics (12%), antibiotics (10%), antihypertensives (10%), gastrointestinal treatments (9%), treatments for colds (9%), and dermatopharmacological preparations (6%). It was surprising that only 16% of the psychic ill patients were treated with drugs, while over 60% of the other illnesses were mostly treated pharmacologically. The interaction with alcohol was the reason for that. The study showed that the practice did not sufficiently reach women and homeless people living on the street. The homeless situation, the personal and social

Environmental prevention strategies in club settings where music and dance events are featured could provide an important new arena for the prevention of drug use and other risky behaviors (e.g., sexual risk taking, intoxication and drug use, aggression, and driving under the influence). Electronic music dance events (EMDEs) occur in clubs that attract young, emerging adults (18-25 years of age) and attract individuals who engage in various types of drug use. Borrowing from the environmental prevention studies that focus on reducing alcohol use and related problems, a model for drug prevention in the club setting is proposed. Initially, an overview of the relationships between EMDEs and drug use and other risky behaviors are presented. Next, rationales for environmental strategies are provided. Finally, an environmental approach to prevention of drug use and risky behaviors in clubs is described. This comprehensive set of environmental strategies, is designed to be mutually supportive and interactive. Environmental strategies are believed to provide potential for developing an efficacious prevention strategy. The environmental prevention approach presented here is composed of three intervention domains: (1) Mobilization, (2) Strategies for the Exterior Environment, and (3) Strategies for the Interior Environment.

This study examined the likelihood that drug users would receive HIV/ AIDS prevention information and supplies (e.g., condoms and bleach) in the rural state of Kentucky. Despite evidence of high HIV risk among criminal justice and substance-using populations, incarceration and substance-user treatment were only minimally associated with prior HIV prevention exposure or HIV testing. These data strongly support the use of criminal justice and treatment settings to provide AIDS prevention interventions for the high-risk drug-using populations they serve, and to target HIV prevention services in rural as well as urban areas.

Objective: To compare the efficacy and the risk of adverse effect of drug susceptibility test guided therapy and novel empirical quadruple therapy for Helicobacter ( H .) pylori infection. Methods: Literature retrieval was conducted by using major databases. Related papers published up to June 2015 were considered eligible if they were randomized control trials comparing different pharmacological formulations for H. pylori infection and used in a network Meta-analysis and a single rate Meta-analysis to evaluate the relative and absolute rates of H. pylori eradication and the risk of adverse effect. The Jadad score was used to evaluate the methodological quality. Funnel plot was constructed to evaluate the risk of publication bias. Begg's rank correlation test or Egger's regression intercept test was done for the asymmetry of funnel plot. Results: Twenty randomized control trials for the treatment of 6 753 initial treated patients with H. pylori infection were included. Drug susceptibility test guided therapy was significantly superior to concomitant therapy, hybrid therapy, sequential therapy and bismuth quadruple therapy. The culture-based therapy had the highest likelihood of improving clinical efficacy, with lowest risk of adverse effect. Concomitant therapy had the highest probability of causing adverse effect despite its effectiveness. Hybrid therapy and bismuth quadruple therapy were associated with lower risk of adverse effect and higher effectiveness. Conclusion: Drug susceptibility test guided therapy showed superiority to other 4 interventions for H. pylori eradication mentioned above. Hybrid therapy and bismuth quadruple therapy might be applied in the settings where the culture-based strategy is not available.

Post-thrombotic syndrome (PTS) is a long-term complication of deep vein thrombosis (DVT) that is characterised by chronic pain, swelling, and skin changes in the affected limb. One of every three people with DVT will develop post-thrombotic complications within five years. Several non-pharmaceutical measures are used for prevention of post-thrombotic syndrome during the acute phase of DVT. These include elevation of the legs and compression therapy. Clinicians and guidelines differ in their assessment of the utility of compression therapy for treatment of DVT. This is an update of a review first published in 2003. To determine relative effectiveness and rate of complications when compression therapy is used in people with deep vein thrombosis (DVT) for prevention of post-thrombotic syndrome (PTS). For this update, the Cochrane Vascular Information Specialist (CIS) searched the Cochrane Vascular Specialised Register (20 March 2017) and CENTRAL (2017, Issue 2). The CIS also searched trial registries for details of ongoing or unpublished studies. We included randomised controlled trials (RCTs) and controlled clinical trials (CCTs) of compression therapy, such as bandaging and elastic stockings, in people with clinically confirmed DVT. The primary outcome was the occurrence of PTS. Two review authors (DK and EvL) identified and assessed titles and abstracts for relevance, and a third review author (DA) verified this assessment independently. Review authors imposed no restrictions on date or language of publications. Three review authors (DA, DK, EvL) used data extraction sheets to independently extract study data. We resolved disagreements by discussion. We identified 10 RCTs with a total of 2361 participants that evaluated compression therapy. The overall methodological quality of these trials was low. We used only five studies in meta-analysis owing to differences in intervention types and lack of data. Three studies compared elastic compression stockings (pressure

Antineoplastic drugs are one of the pharmacological classes more frequently involved in occurrence of "serious" adverse drug reactions. However, few epidemiological data are available regarding the preventability of adverse drug reactions with ambulatory cancer chemotherapy. We assessed the rate and characteristics of "preventable" or "potentially preventable" "serious" adverse drug reactions induced by oral protein kinase inhibitors (PKIs). We performed a retrospective study with all "serious" adverse drug reactions (ADRs) recorded from 1 January 2008 to 31 December 2009 in the French Pharmacovigilance Database with the eight oral protein kinase inhibitors marketed in France: sorafenib, imatinib, erlotinib, sunitinib, dasatinib, lapatinib, nilotinib and everolimus (Afinitor®) using the French adverse drug reactions preventability scale. This study was carried out on 265 spontaneous notifications. Most of adverse drug reactions were "unpreventable" (63.8 %). Around one third were "unevaluable" due to notifications poorly documented (medical history, dosage, use of drugs as first or second intention, concomitant drugs). One (0.4 %) adverse drug reaction was "preventable" with dasatinib (subdural hematoma) and three (1.1 %) were "potentially preventable" (hepatic adverse drug reactions): two with imatinib and one with sorafenib. For these four cases, we identified some characteristics: incorrect dosages, drug interactions and off-label uses. An appropriate prescription could avoid the occurrence of 1.5 % "serious" adverse drug reactions with oral PKIs. This rate is low and further studies are needed to compare our results by using other preventability instruments and to improve the French ADRs Preventability Scale.

Implantable cardioverter defibrillators (ICDs) used to prevent sudden cardiac arrest in children not only provide appropriate therapy in 25% of patients but also result in a significant incidence of inappropriate shocks and other device complications. ICDs placed for secondary prevention have higher rates of appropriate therapy than those placed for primary prevention. Pediatric patients with primary prevention ICDs were studied to determine time-dependent incidence of appropriate use and adverse events. A total of 140 patients aged prevention were retrospectively identified. Demographics and times to first appropriate shock; adverse events (including inappropriate shock, lead failure, reintervention, and complication); generator replacement and follow-up were noted. During mean follow-up of 4 years, appropriate shock occurred in 19% patients and first adverse event (excluding death/transplant) occurred in 36%. Risk of death or transplant was ≈1% per year and was not related to receiving appropriate therapy. Conditional survival analysis showed rates of appropriate therapy and adverse events decrease soon after implantation, but adverse events are more frequent than appropriate therapy throughout follow-up. Primary prevention ICDs were associated with appropriate therapy in 19% and adverse event in 36% in this cohort. The incidence of both first appropriate therapy and device-related adverse events decreased during longer periods of follow-up after implantation. This suggests that indications for continued device therapy in pediatric primary prevention ICD patients might be reconsidered after a period of nonuse. © 2014 American Heart Association, Inc.

Potent cholinesterase inhibitors (e.g., soman, sarin), induce a wide range of deleterious effects including convulsions, behavioral impairments and ultimately, death. Due to the likelihood of various scenarios of military or terrorist attacks by these and other chemical weapons, research has to be aimed at finding optimal therapies. Early accumulation of acetylcholine in synaptic clefts was suggested to trigger an array of toxic events including an excessive release of glutamate, culminating in the activation of its receptors. Stimulation of the N-Methyl-D-Aspartate (NMDA) subtype of these receptors was associated with the neuronal injury that initiates organophosphate-induced brain damage. The notion of a stepwise mechanism yielded treatments based on a combination of an immediate administration of enzyme reactivators and anticholinergic drugs. This strategy dramatically increased survival rates but did not abolish convulsions and failed to prevent the ensuing cognitive dysfunction. Efforts to improve this paradigm by adding anticonvulsants or antiglutamatergic drugs with anti-epileptic characteristics produced dubious results. Under these conditions, benactyzine and caramiphen, agents with anticholinergic and antiglutamatergic properties, provided improved protection when introduced as adjunct agents to oximes, reversible cholinesterase inhibitors and/or specific antimuscarinic drugs such as atropine. In contrast, the specific antimuscarinic drug scopolamine failed to block soman-induced changes in glutamatergic and behavioral parameters even when given prophylactically. These findings along with a large number of additional reports led towards the conclusion that the therapeutic advantage of drugs such as benactyzine and caramiphen could derive from their ability to modulate central cholinergic and glutamate neurotransmission

Lack of robust program evaluation has hindered the effectiveness of school-based drug abuse prevention curricula overall. Independently evaluated randomized controlled trials (RCTs) of universal, middle school-based drug abuse prevention curricula are the most useful indicators of whether such programs are effective or ineffective. To conduct a systematic review identifying independently evaluated RCTs of universal, middle school-based drug abuse prevention curricula; extract data on study quality and substance use outcomes; and assess evidence of program effectiveness. PsycInfo, Educational Resources Information Center, Science Citation Index, Social Science Citation Index, Cumulative Index to Nursing and Allied Health Literature, MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews were searched between January 1, 1984, and March 15, 2015. Search terms included variations of drug, alcohol, tobacco, and marijuana use, as well as school, prevention, and effectiveness. Studies included in the review were RCTs carried out by independent evaluators of universal school-based drug prevention curricula available for dissemination in the United States that reported alcohol, tobacco, marijuana, or other drug use outcomes. Two researchers extracted data on study quality and outcomes independently using a data extraction form and met to resolve disagreements. A total of 5071 publications were reviewed, with 13 articles meeting final inclusion criteria. Of the 13 articles, 6 RCTs of 4 distinct school-based curricula were identified for inclusion. Outcomes were reported for 42 single-drug measures in the independent RCTs, with just 3 presenting statistically significant (P drug prevention curricula. Independent evaluations show little evidence of effectiveness for widely used programs. New methods may be necessary to approach school-based adolescent drug prevention.
Full Text Available Drug use is one of the major challenges that todays society faces; its effects are felt at the level of various social, professional and age categories. Over 50 non-profit organizations are involved in the development of anti-drug social programs in Romania. Their role is to improve the degree of awareness of the target population concerning the risks associated with drug use, but also to steer consumers towards healthy areas, beneficial to their future. This paper aims to detail the issue of drug use in Romania, by making predictions based on the evolution of this phenomenon during the next five years. The obtained results have revealed the necessity to increase the number of programs preventing drug use, aswell as the need to continue social programs that have proved effective in previous years.
Full Text Available Abstract Background New HIV diagnoses related to injection drug use (IDU have declined in the United States. Access to clean syringes and decreasing HIV transmission among injection drug users have been HIV prevention priorities of the Rhode Island (RI HIV community. To examine trends in IDU-related new HIV diagnoses in RI, we performed a retrospective analysis of new HIV diagnoses according to HIV risk factor from 1990–2003. Results There has been an 80% absolute reduction in IDU-related new HIV diagnoses in RI coincident with IDU-specific prevention efforts. Conclusion There has been a greater decline in IDU-related new HIV diagnoses in Rhode Island compared to national data reported by the Centers for Disease Control and Prevention. We hypothesize that this dramatic decline in Rhode Island is related to extensive HIV prevention efforts targeting IDUs. Further research is needed to examine the impact of specific HIV prevention interventions for injection drug users.

Osteoporosis has become an increasing concern for older people as it may potentially lead to osteoporotic fractures. This study is designed to assess the efficacy and safety of ten therapies for post-menopausal women using network meta-analysis. We conducted a systematic search in several databases, including PubMed and Embase. A random-effects model was employed and results were assessed by the odds ratio (OR) and corresponding 95% confidence intervals (CI). Furthermore, with respect to each outcome, each intervention was ranked according to the surface under the cumulative ranking curve (SUCRA) value. With respect to preventing new vertebral fractures (NVF), all ten drugs outperformed placebo, and etidronate proved to be the most effective treatment (OR 0.24, 95% CI 0.14 to 0.39). In addition, zoledronic acid and parathyroid hormone ranked higher compared with the other drugs. With respect to preventing clinical vertebral fractures (CVF), zoledronic acid proved to be the most effective drug (OR = 0.25, 95% CI 0.08 to 0.92), with denosumab as a desirable second option (OR = 0.48, 95% CI 0.22 to 0.96), when both were compared with placebo. As for adverse events (AE) and severe adverse events (SAE), no significant difference was observed. According to SUCRA, etidronate ranked first in preventing CVF; parathyroid hormone and zoledronic acid ranked highly in preventing NVF and CVF. Raloxifene was safe with a high rank in preventing AEs and SAEs though performed unsatisfactorily in efficacy. This study suggests that, taking efficacy and safety into account, parathyroid hormone and zoledronic acid had the highest probability of satisfactory performance in preventing osteoporotic fractures.

Full Text Available Capsule endoscopy and balloon endoscopy, advanced modalities that allow full investigation of the entire small intestine, have revealed that nonsteroidal anti-inflammatory drugs (NSAIDs can cause a variety of abnormalities in the small intestine. Recently, several reports show that traditional NSAIDs (tNSAIDs and acetylsalicylic acid (ASA can induce small intestinal injuries. These reports have shown that the preventive effect of proton pump inhibitors (PPIs does not extend to the small intestine, suggesting that concomitant therapy may be required to prevent small intestinal side effects associated with tNSAID/ASA use. Recently, several randomized controlled trials used capsule endoscopy to evaluate the preventive effect of mucoprotective drugs against tNSAID/ASA-induced small intestinal injury. These studies show that misoprostol and rebamipide reduce the number and types of tNSAID-induced small intestinal mucosal injuries. However, those studies were limited to a small number of subjects and tested short-term tNSAID/ ASA treatment. Therefore, further extensive studies are clearly required to ascertain the beneficial effect of these drugs.

The purpose of this study was twofold. First, pretreatment correlations are presented among impulsivity, intoxicant use, HIV risk behavior, spirituality, and motivation in a sample of 38 HIV-positive drug users. Second, treatment outcomes are presented from a preliminary study of spiritual self-schema (3-S(+)) therapy - a manual-guided psychotherapy integrating cognitive and Buddhist psychologies - for increasing motivation for abstinence, HIV prevention, and medication adherence. Impulsivity was negatively correlated with spiritual practices and motivation for recovery, and was positively related to intoxicant use and HIV risk behavior. Relative to a standard care comparison condition, patients completing 3-S(+) therapy reported greater decreases in impulsivity and intoxicant use, and greater increases in spiritual practices and motivation for abstinence, HIV prevention, and medication adherence.

Background: The study was done to compare the early pregnancy loss rate in women with polycystic ovarian syndrome who received or did not receive metformin in pregnancy. Study type, settings and duration: A case control interventional study carried out at Civil Hospital Karachi, Hamdard University Hospital and Private Gynaecology clinics from January 2005 to July 2008. Subjects and Methods Eighty two non diabetic patients with polycystic ovarian syndrome who became pregnant were included in the study. A questionnaire was filled for all patients that included information on basic demography and mean age, parity, weight. Fasting blood sugar and serum insulin levels were done for all these women. Only patients with raised insulin levels (more than 10 mu/l) were included in the study and all were offered to use oral metformin throughout pregnancy as 500 mg three times a day with folic acid supplements 5 mg once daily. Those who agreed to take the drug throughout pregnancy and to comply with the therapy were taken as cases, while those who did not agree to take the medicine acted as controls. Patients with other causes of recurrent pregnancy loss were excluded from the study. All pregnancies were followed using serial ultrasound examination to see any pregnancy loss in the two groups. Eighty two cases of polycystic ovaries with pregnancy were seen during the study period. All cases had raised serum insulin levels. Fifty patients agreed to take metformin through out pregnancy while, 32 cases did not agree to take metformin during pregnancy and thus acted as controls. The two groups did not differ in mean age, parity, weight and mean fasting blood sugar levels. Fasting insulin levels were high in metformin group (18.40 mu/l ) than in controls (12.53 mu/l). Missed abortion rate was significantly lower (12%) in metformin group than in controls (28%) (p<0.028). No congenital anomalies were found in both the groups on ultrasound at 16-19 weeks.

The new drug, AHR 5645B, together with other drugs was evaluated in tests, conducted with eight male subjects, concerning its ability to prevent motion sickness. It was found that AHR 5645B, used in doses of 20, 50, and 100 mg, was not efficacious in preventing experimental motion sickness. A combination of 50 mg meclizine and 25 mg ephedrine sulfate produced the best results. Favorable results were also obtained with a combination of 12.5 mg promethazine hydrochloride and 12.5 mg ephedrine sulfate. The findings in the reported experiment point to the difficulty of identifying a highly efficacious antimotion sickness drug for everyone.

TEMPRANO was a multicentre, open-label trial in which human immunodeficiency virus (HIV) infected adults with high CD4 counts were randomised into early or deferred antiretroviral therapy (ART) arms with or without 6-month isoniazid preventive therapy (IPT) in a setting where the World Health Organization (WHO) recommends IPT in HIV-infected patients. Despite the WHO recommendation, IPT coverage remains low due to fear of the presence of undiagnosed active TB before prescribing IPT, and the related risk of drug resistance. To report the frequency of undiagnosed TB in patients enrolled for IPT and describe the results of a 1-month buffer period to avoid prescribing IPT for active TB cases. Patients were screened using a clinical algorithm and chest X-ray at Day 0 and started on isoniazid at Month 1 if no sign/symptom suggestive of TB appeared between Day 0 and Month 1. Of 1030 patients randomised into IPT arms. 10% never started IPT at Month 1. Of these, 23 had active TB, including 16 with prevalent TB. Among the 927 patients who started IPT, 6 had active TB, including 1 with prevalent TB. Only 1 patient with active TB received IPT due to the 1-month buffer period between Day 0 and IPT initiation. In this study, 1.6% of adults considered free of active TB based on clinical screening at pre-inclusion actually had active TB.
Full Text Available A promising strategy for drug abuse treatment is to accelerate the drug metabolism by administration of a drug-metabolizing enzyme. The question is how effectively an enzyme can actually prevent the drug from entering brain and producing physiological effects. In the present study, we have developed a pharmacokinetic model through a combined use of in vitro kinetic parameters and positron emission tomography data in human to examine the effects of a cocaine-metabolizing enzyme in plasma on the time course of cocaine in plasma and brain of human. Without an exogenous enzyme, cocaine half-lives in both brain and plasma are almost linearly dependent on the initial cocaine concentration in plasma. The threshold concentration of cocaine in brain required to produce physiological effects has been estimated to be 0.22±0.07 µM, and the threshold area under the cocaine concentration versus time curve (AUC value in brain (denoted by AUC2(∞ required to produce physiological effects has been estimated to be 7.9±2.7 µM·min. It has been demonstrated that administration of a cocaine hydrolase/esterase (CocH/CocE can considerably decrease the cocaine half-lives in both brain and plasma, the peak cocaine concentration in brain, and the AUC2(∞. The estimated maximum cocaine plasma concentration which a given concentration of drug-metabolizing enzyme can effectively prevent from entering brain and producing physiological effects can be used to guide future preclinical/clinical studies on cocaine-metabolizing enzymes. Understanding of drug-metabolizing enzymes is key to the science of pharmacokinetics. The general insights into the effects of a drug-metabolizing enzyme on drug kinetics in human should be valuable also in future development of enzyme therapies for other drugs of abuse.

The article deals with analysis of the laws "On prevention of alcoholism, drug addiction and toxicomania" introduced in some subjects of the Russian Federation (Permskaya, Tomskaya, Murmanskaya oblast, the Republics of Bashkortostan, Mordovia, Buryatia, Mari El, etc.). The laws stipulate the participation of the authorities of public and municipal administration, public health, social protection, home affairs and others in the prevention activities. The integral part of this activity is the approval of corresponding regional programs with adequate financing and coordination. The laws on prevention of alcoholism, drug addiction and toxicomania, adopted in the subjects of the Russian Federation are of advance character and testify the necessity of adoption of relevant Federal law.

This research was conducted to compare the effects of drug therapy, physical therapy, and exercise on pain, disability, and depression in patients with chronic low back pain. The research design of this study was a nonequivalent control group pretest-posttest design. The subjects of this study were 28 patients for the drug therapy & physical therapy, 24 patients for the drug therapy & exercise, and 22 patients for the physical therapy & exercise. Data was collected by MVAS, Oswestry disability questionnaires, and questionnaires of depression. It was analyzed by paired t-test for effectiveness, ANOVA, and Scheffe for comparison of the effects of the 3 experimental treatments, using SPSS/WIN 12.0. There were no effects of drug therapy & physical therapy on pain, disability, and depression. However, there were effects of drug therapy & exercise and the physical therapy & exercise on pain, disability, and depression. The effects of physical therapy & exercise on pain, disability, and depression were the greatest, but there was no statistically significant differences between the drug therapy & exercise and the physical therapy & exercise. Exercise is regarded as a more effective and easily accessible nursing intervention to apply alone than drug therapy or physical therapy simultaneously in reducing pain, disability and depression.
Full Text Available Over the past few years there have been several randomized controlled trials that examine the effect of lifestyle modification and pharmacological interventions on the likelihood of developing diabetes mellitus (DM type 2 in people at high risk. These studies demonstrated that the number of people newly diagnosed with diabetes within 3–6-year period may be considerably reduced. Therefore focus of discussing the tactics to control DM type 2 is shifted from the relatively narrow topic of treatment of the disease at a wide range of issues of its prophylaxis: prevention of development and early treatment of DM, aimed to stabilization or reverse progression of the disease and prevention of its progression. This review discusses the general concept and the evidence base on preventing DM type 2 in the context of the pathogenesis of the disease. In addition, the attention is paid to the possibilities of the use of the discussed approaches to clinical practice, taking into account pathogenetic features of the disease and and clinical findings.

Epigenetics is independent of the sequence events that physically affect the condensing of chromatin and genes expression. The unique epigenetic memories of various cells trigger exclusive gene expression profiling. According to different studies, the aberrant epigenetic signatures and impaired gene expression profiles are master occurrences in cancer cells in which oncogene and tumor suppressor genes are affected. Owing to the facts that epigenetic modifications are performed earlier than expression and are reversible, the epigenetic reprogramming of cancer cells could be applied potentially for their prevention, control, and therapy. The disruption of the acetylation signature, as a master epigenetic change in cancers, is related to the expression and the activity of HDACs. In this context, class I HDACs play a significant role in the regulation of cell proliferation and cancer. More recently, cancer stem cell (CSC) has been introduced as a minority population of tumor that is responsible for invasiveness, drug resistance, and relapse of cancers. It is now believed that controlling CSC via epigenetic reprogramming such as targeting HDACs could be helpful in regulating the acetylation pattern of chromatin. Recently, a number of reports have introduced some phytochemicals as HDAC inhibitors. The use of phytochemicals with the HDAC inhibition property could be potentially efficient in overcoming the mentioned problems of CSCs. This review presents a perspective concerning HDAC-targeted phytochemicals to control CSC in tumors. Hopefully, this new route would have more advantages in therapeutic applications and prevention against cancer. Copyright © 2017. Published by Elsevier Masson SAS.

Apnea of prematurity (AOP) is a common complication of preterm birth, which affects more than 80 % of neonates with a birth weight less than 1,000 g. Methylxanthine therapies, including caffeine and theophylline, are a mainstay in the treatment and prevention of AOP. Despite their frequent use, little is known about the long-term safety and efficacy of these medications. In this review, we systematically evaluated the literature on neonatal methylxanthine therapies and found that caffeine is associated with fewer adverse effects and a wider therapeutic window when compared with theophylline. When used as a therapeutic agent, larger doses of caffeine citrate have been shown to improve acute neonatal outcomes when administered promptly, although further studies are needed to assess the long-term neurological consequences associated with the use of large loading doses. In a secondary analysis of data obtained from a randomized controlled trial, the prophylactic use of caffeine was associated with substantial cost savings and improved clinical outcomes. However, there remains a paucity of well-controlled, randomized clinical trials that have examined the use of caffeine as a prophylactic agent, and further prospective trials are needed to determine if caffeine is a safe and effective prophylactic agent. Additionally, measuring plasma concentrations longitudinally as a marker of therapeutic efficacy and/or toxicity has not been shown to be clinically useful in neonates who are responsive to treatment and exhibit no signs or symptoms of toxicity. However, in cases where toxicity is of concern or for neonates with congenital or pathophysiologic process that may alter the pharmacokinetics of these drugs, therapeutic drug monitoring may be warranted to monitor for methylxanthine toxicity.

Apnea of prematurity (AOP) is a common complication of preterm birth, which affects more than 80 % of neonates with a birth weight less than 1,000 g. Methylxanthine therapies, including caffeine and theophylline, are a mainstay in the treatment and prevention of AOP. Despite their frequent use, little is known about the long-term safety and efficacy of these medications. In this review, we systematically evaluated the literature on neonatal methylxanthine therapies and found that caffeine is associated with fewer adverse effects and a wider therapeutic window when compared with theophylline. When used as a therapeutic agent, larger doses of caffeine citrate have been shown to improve acute neonatal outcomes when administered promptly, although further studies are needed to assess the long-term neurological consequences associated with the use of large loading doses. In a secondary analysis of data obtained from a randomized controlled trial, the prophylactic use of caffeine was associated with substantial cost savings and improved clinical outcomes. However, there remains a paucity of well-controlled, randomized clinical trials that have examined the use of caffeine as a prophylactic agent, and further prospective trials are needed to determine if caffeine is a safe and effective prophylactic agent. Additionally, measuring plasma concentrations longitudinally as a marker of therapeutic efficacy and/or toxicity has not been shown to be clinically useful in neonates who are responsive to treatment and exhibit no signs or symptoms of toxicity. However, in cases where toxicity is of concern or for neonates with congenital or pathophysiologic process that may alter the pharmacokinetics of these drugs, therapeutic drug monitoring may be warranted to monitor for methylxanthine toxicity.

People who inject drugs are more likely to be HIV positive and to have a mental disorder than the general population. We explore how the detection and treatment of mental illness among people who are injecting drugs are essential to primary and secondary prevention of HIV infection in this population. Aside from opioid addiction, few studies have been conducted on the links between mental disorders and injection-drug use. However, independent of the injection-drug use literature, a growing number of studies demonstrate that untreated mental illness, especially depression and alcohol/substance use disorders, is associated with HIV-related risk behaviors, acquiring HIV infection, failure to access HIV care and treatment, failure to adhere to HIV care and treatment, and increased morbidity and mortality from HIV-related diseases and comorbidities. In our review of both the published literature and gray literature we found a dearth of information on models for providing care for both opioid addiction and other mental illnesses regardless of HIV status, particularly in low- and middle-income countries. We therefore make recommendations on how to address the mental health needs of HIV-positive people who inject drugs, which include the provision of opioid substitution therapy and integrated mental health, substance abuse, and HIV services.

This special issue exemplifies one of the major goals of the current editor of Experimental and Clinical Psychopharmacology (Dr. Suzette Evans): to increase the number of manuscripts that emphasize females and address sex differences. Taken together, these articles represent a broad range of drug classes and approaches spanning preclinical research to treatment to better understand the role of sex differences in drug abuse. While not all studies found sex differences, we want to emphasize that finding no sex difference is just as important as confirming one, and should be reported in peer-reviewed journals. It is our intention and hope that this special issue will further advance scientific awareness about the importance of accounting for sex differences in the study of substance abuse. Participant sex is an essential variable to consider in developing a more comprehensive understanding of substance abuse. Rather than viewing investigating sex differences as burdensome, investigators should seize this opportune area ripe for innovative research that is long overdue. (c) 2015 APA, all rights reserved).

Full Text Available Fostering excitement in pharmacy student learning can be achieved through reinforcing drug therapies in curricular and extracurricular endeavors. This paper described an extracurricular initiative that elevated awareness of drug therapy in its current, future, and past members. This process occurred on an annual basis. Upon invitation, participants were expected to attend meetings with current and graduate organizational members. These settings provided opportunities for recognition and remembrance of organizational history and drug therapies. Checkpoints were inserted to verify progression towards full membership. The primary role of graduate members in this process was the yielding of their professional insights. A student – led, peer – facilitated model of drug therapy exposure along these lines resonates with calls for increased innovative learning strategies.

Full Text Available The aim of the study is a comparative analysis of the effect of melatonin (Melaxen and 3-hydroxypyridine (Mexidol on antitumor and antimetastatic influence of chemoradiotherapy and oxidative status at mice with Lewis lung carcinoma. Material — Experiments have been organized on 95 mice of C57Bl/6 line and of 20–22 g in weight. Cyclophosphan has been abdominally administered two times in a dosage of 60 mg/kg within the interval of 120 hours — 20-30 min before radiotherapy. It has been located on the area of initial tumor in a dosage of 2 g at the same time as cyclophosphan injection. Melaxen and Mexidol have been intramuscularly injecting in the dosage of 45 and 50 mg/ kg for 14 days. Antitumor and antimetastatic effect of the applied therapy and changes in the oxidative status of the animals have been estimated. Results — Melaxen and Mexidol do not decrease antitumour and antimetastatic effects of radiotherapy and prevent the activation of free radical processes at animals with tumors. Mexidol was more effective than Melaxen in correction of superoxide dismutase activity in liver. The drugs under the study do not decrease radiotherapy-induced lipid peroxidation in the initial tumor. Conclusion — Melaxen and Mexidol do not decrease the radio therapy efficiency and oxidative status at mice with tumor (on the background of antitumor treatment.

The purpose of this study was to assess the value of sucralfate suspension in prevention of oral mucositis and for reduction of oral pain in patients who develop mucositis during radiation therapy. The study was a double-blind, placebo-controlled, randomized prospective trial of a sucralfate suspension in the prevention and management of oral mucositis during radiation therapy. Oral mucositis was assessed using a quantitative scale and symptoms were assessed using visual analogue scales. The statistical model was developed to detect a 40% reduction in mucositis. No statistically significant reduction in mucositis was seen. Early during radiation therapy less oral pain was reported in the sucralfate group, but as treatment progressed all patients experienced pain. Patients in the sucralfate group were prescribed topical and systemic analgesics later in the course of radiation therapy. Prophylactic oral rinsing with sucralfate did not prevent oral ulcerative mucositis. Sucralfate may reduce the experience of pain during radiation therapy. 32 refs., 3 tabs

Concern about the drug lag, the delay in marketing approval between one country and another, for anticancer drugs has increased in Japan. Although a number of studies have investigated the drug lag, none has investigated it in relation to the transition of anticancer therapy from traditional cytotoxic drugs to molecularly targeted agents. Our aim was to investigate current trend in oncology drug lag between the US and Japan and identify oncology drugs approved in only one of the two countries. Publicly and commercially available data sources were used to identify drugs approved in the US and Japan as of 31 December 2010 and the data used to calculate the drug lag for individual drugs. Fifty-one drugs were approved in both the US and Japan, whereas 34 and 19 drugs were approved only in the US or Japan, respectively. Of the 19 drugs approved only in Japan, 12 had not been subject to development for a cancer indication in the US, and all were approved before 1996 in Japan. Of the 34 drugs approved only in the US, 20 had not been subject to development in Japan, and none was in the top 25 by annual US anticancer drug-class sales. For drugs approved in both countries, the mean approval lag of the molecularly targeted drugs (MTDs) was significantly shorter than that of the non-molecularly targeted drugs (non-MTDs) (3·3 vs. 5·4 years). Further, mean R&D time of the MTDs was significantly shorter than that of non-MTDs (10·0 vs. 13·7 years). The price of MTDs had increased on average by 6·6% annually in the US, whereas it had decreased on average by 4·3% biyearly in Japan. The emergence of new molecularly targeted agents has contributed to reducing the approval lag, most likely due to improvements in R&D strategy. © 2012 Blackwell Publishing Ltd.

Randomized-trial data on the risks and benefits of antiretroviral therapy (ART) as compared with zidovudine and single-dose nevirapine to prevent transmission of the human immunodeficiency virus (HIV) in HIV-infected pregnant women with high CD4 counts are lacking. We randomly assigned HIV-infected women at 14 or more weeks of gestation with CD4 counts of at least 350 cells per cubic millimeter to zidovudine and single-dose nevirapine plus a 1-to-2-week postpartum "tail" of tenofovir and emtricitabine (zidovudine alone); zidovudine, lamivudine, and lopinavir-ritonavir (zidovudine-based ART); or tenofovir, emtricitabine, and lopinavir-ritonavir (tenofovir-based ART). The primary outcomes were HIV transmission at 1 week of age in the infant and maternal and infant safety. The median CD4 count was 530 cells per cubic millimeter among 3490 primarily black African HIV-infected women enrolled at a median of 26 weeks of gestation (interquartile range, 21 to 30). The rate of transmission was significantly lower with ART than with zidovudine alone (0.5% in the combined ART groups vs. 1.8%; difference, -1.3 percentage points; repeated confidence interval, -2.1 to -0.4). However, the rate of maternal grade 2 to 4 adverse events was significantly higher with zidovudine-based ART than with zidovudine alone (21.1% vs. 17.3%, P=0.008), and the rate of grade 2 to 4 abnormal blood chemical values was higher with tenofovir-based ART than with zidovudine alone (2.9% vs. 0.8%, P=0.03). Adverse events did not differ significantly between the ART groups (P>0.99). A birth weight of less than 2500 g was more frequent with zidovudine-based ART than with zidovudine alone (23.0% vs. 12.0%, P<0.001) and was more frequent with tenofovir-based ART than with zidovudine alone (16.9% vs. 8.9%, P=0.004); preterm delivery before 37 weeks was more frequent with zidovudine-based ART than with zidovudine alone (20.5% vs. 13.1%, P<0.001). Tenofovir-based ART was associated with higher rates than

Full Text Available Aim. Development and implementation of novel organizational management technologies of medical care aimed at formation of adherence to drug therapy in patients from rural areas and calculation of medical and economic efficiency of implementation of this project. Methods. The study subject was the population of Rybnaya Sloboda district of the Republic of Tatarstan. Patient recruitment into the groups was conducted in the polyclinic of Rybnaya Sloboda central regional hospital. The duration of the study was 6 months for each of two groups with further follow-up and evaluation of adherence to therapy for 2 months. Results. Annually stroke affects 5.6 to 6.6 million of people around the world, 35% of whom die in the acute period. Recently, serious rejuvenation of cardiovascular disorders has been observed. The main reason for such trend is low patients’ compliance to drug therapy. And patients’ compliance itself allows significantly decreasing the risk of cardiovascular complications. The article discussed the issues of low compliance to drug therapy, presents the methods of its formation in patients from rural area. The examples of foreign and Russian experience of increasing patients’ compliance to drug therapy are described and the key intervention points for patients are determined. On the basis of conducted analysis, implementation was developed and suggested for patient-oriented program aimed at formation of adherence to drug therapy of rural population. Also, the authors performed evaluation of medical and economic efficiency of implementation of a patient-oriented program aimed at formation of adherence to drug therapy of rural population (assessment of expenditures for medications, hospital stay, incapacity related to the main disease; evaluation of expenditures for prevention of complications and disability. Conclusion. Effective organization of prophylactic activity is of great importance for prevention of cardiovascular disease

In this article, the test implementation of a school-oriented drug prevention program "Study without Drugs" is discussed. The aims of this study were to determine the results of the process evaluation and to determine whether the proposed school-oriented drug prevention program during a pilot project was effective for the participating pupils. Sixty second-grade pupils at a junior high school in Paramaribo, Suriname participated in the test implementation. They were divided into two classes. For the process evaluation the students completed a structured questionnaire focusing on content and teaching method after every lesson. Lessons were qualified with a score from 0-10. The process was also evaluated by the teachers through structured interviews. Attention was paid to reach, dose delivered, dose received, fidelity, connection, achieved effects/observed behaviors, areas for improvement, and lesson strengths. The effect evaluation was conducted by using the General Liniair Model (repeated measure). The research (-design) was a pre-experimental design with pre-and post-test. No class or sex differences were detected among the pupils with regard to the assessment of content, methodology, and qualification of the lessons. Post-testing showed that participating pupils obtained an increased knowledge of drugs, their drug-resisting skills were enhanced, and behavior determinants (attitude, subjective norm, self-efficacy, and intention) became more negative towards drugs. From the results of the test implementation can be cautiously concluded that the program "Study without Drugs" may yield positive results when applied in schools). Thus, this pilot program can be considered a step towards the development and implementation of an evidence-based school-oriented program for pupils in Suriname.

At present, only a few studies have assessed the efficacy of intervention programmes that focus on drug prevention at the workplace, and there is only little information available with respect to the development and evaluation of suitable instruments for the evaluation of such prevention programs. Questionnaire procedures, nevertheless, seem to be basically suitable. We developed and evaluated the questionnaire for the evaluation of drug preventive intervention programs at the workplace (FEBSI) to provide a suitable instrument to assess the effectiveness of programmes that focus on drug prevention at the workplace. We assessed and analysed data for the evaluation of this questionnaire in the context of a prevention programme in two large industrial companies. We found a three-factor solution with satisfying reliability scores for each factor. The extracted factors of the questionnaire reflect the following areas: consequences of substance use at work, compliance with employment agreements, and knowledge and behaviour. Programme participants could be reliably distinguished from non-participants by using the FEBSI. So far, the questionnaire seems to be a suitable and reliable instrument for the evaluation of drug prevention programmes.

Male mixed-breed dogs were used to evaluate the effectiveness of cimetidine (Cim), promethazine (Pro), and thiethylperazine (Thi), singly and in combination, to raise the threshold for radiation-induced emesis. Cim was chosen as an H/sub 2/ antihistamine, Pro as an H/sub 1/ antihistamine, and Thi as a phenothiazine derivative dopamine blocker. Doses were calculated to approximate doses for an average human. Exposure was to /sup 60/Co at 60 rad (midline) per min. The dogs were fed 0.4 kg canned dog food 1 hour before exposure, and injected with the appropriate drugs 30 minutes prior to exposure. Emesis onset times, number of episodes, and time to last episode were recorded. The radiation dose (midline tissue rad) to cause a 50% incidence of emesis (ED/sub 50/) was calculated using an up-and-down procedure. The ED/sub 50/ were: 258 (212-315) for controls; 240 (151-380) for Cim; 313 (256-384) for Pro; 405 (319-514) for Thi; 334 (284-394) for Cim + Pro; 446 (365-546) for Cim + Thi; 347 (306-399) for Pro + Thi; and 478 (428-539) for Cim + Pro + Thi.
Full Text Available L-dopa is the most effective, currently available treatment for Parkinson’s disease (PD, but it leads to the development of involuntary movements known as L-dopa-induced dyskinesia (LID in the majority of patients after long-term use. Both gene and cell therapy approaches are the subject of multiple ongoing studies as potential ways of relieving symptoms of PD without the complication of dyskinesia. However, the spectre of dyskinesia in the absence of L-dopa, the so-called “off-phase” or graft-induced dyskinesia (GID, remains a major obstacle particularly in the further development of cell therapy in PD, but it is also a concern for proponents of gene therapy approaches. LID results from nonphysiological dopamine release, supersensitivity of dopamine receptors, and consequent abnormal signalling through mechanisms of synaptic plasticity. Restoration of physiological circuitry within the basal ganglia loops is ultimately the aim of all cell and gene therapy approaches but each using distinctive strategies and accompanied by risks of exacerbation of LID or development of “off-phase”/GID. In this paper we discuss the details of what is understood regarding the development of dyskinesias with relevance to cell and gene therapy and potential strategies to minimize their occurrence.

Limited data are available regarding the evolution over time of the rate of sudden unexpected death in epilepsy patients (SUDEP) in drug-resistant epilepsy. The objective is to analyze a database of 40 443 patients with epilepsy implanted with vagus nerve stimulation (VNS) therapy in the United States (from 1988 to 2012) and assess whether SUDEP rates decrease during the postimplantation follow-up period. Patient vital status was ascertained using the Centers for Disease Control and Prevention's National Death Index (NDI). An expert panel adjudicated classification of cause of deaths as SUDEP based on NDI data and available narrative descriptions of deaths. We tested the hypothesis that SUDEP rates decrease with time using the Mann-Kendall nonparametric trend test and by comparing SUDEP rates of the first 2 years of follow-up (years 1-2) to longer follow-up (years 3-10). Our cohort included 277 661 person-years of follow-up and 3689 deaths, including 632 SUDEP. Primary analysis demonstrated a significant decrease in age-adjusted SUDEP rate during follow-up (S = -27 P = .008), with rates of 2.47/1000 for years 1-2 and 1.68/1000 for years 3-10 (rate ratio 0.68; 95% confidence interval [CI] 0.53-0.87; P = .002). Sensitivity analyses confirm these findings. Our data suggest that SUDEP risk significantly decreases during long-term follow-up of patients with refractory epilepsy receiving VNS Therapy. This finding might reflect several factors, including the natural long-term dynamic of SUDEP rate, attrition, and the impact of VNS Therapy. The role of each of these factors cannot be confirmed due to the limitations of the study. © 2018 The Authors.

In the world, bone tuberculosis is still very difficult to treat and presents a challenge to clinicians. In this study, we utilized 3D printing technology to fabricate a programmed release multi-drug implant for bone tuberculosis therapy. The construction of the drug implant was a multi-layered concentric cylinder divided into four layers from the center to the periphery. Isoniazid and rifampicin were distributed individually into the different layers in a specific sequence of isoniazid-rifampicin-isoniazid-rifampicin. The drug release assays in vitro and in vivo showed that isoniazid and rifampicin were released orderly from the outside to the center to form the multi-drug therapeutic alliance, and the peak concentrations of drugs were detected in sequence at 8 to 12 day intervals. In addition, no negative effect on the proliferation of rabbit bone marrow mesenchymal stem cells was detected during the cytocompatibility assay. Due to its ideal pharmacologic action and cytocompatibility, the programmed release multi-drug implant with a complex construction fabricated by 3D printing technology could be of interest in prevention and treatment of bone tuberculosis.

To examine the significant differences in smoking, drug and alcohol use between adolescent boys and girls, and to raise the possible need to design and implement prevention programs from a gender perspective. A qualitative study using eight discussion groups of adolescents aged 14-18 years (n=56) and 6 semi-structured interviews with experts and professionals in drug prevention in the Community of Madrid. Categorical interpretive analysis was performed. The adolescents and prevention professional indicated differences between boys and girls in drug and alcohol use. The significances, reasons associated with the consumption and the patterns of consumption were perceived differently by each sex. To lose weight, calm down or an image of rebelliousness was related to girls who smoked, while boys smoked less because they did more sports. The perception of certain precocity of drug consumption was associated with the step from school to Higher Education Institutions. They found smoking associated with a good social image among their groups. Adolescents showed the ineffectiveness of the campaigns and prevention messages they received, incoherence of adults between messages and actions, and the attraction of all behaviours that are banned. Professionals observed the need to include a gender perspective in prevention programs, but did not know how to achieve it, mainly because it has been translated into different activities for each sex until now. The significant differences associated with smoking, drug and alcohol use observed in the adolescents should lead us to design and implement prevention programs that incorporate a gender perspective. It is perhaps from this strategy where drug and alcohol use among girls can be reduced. Copyright © 2012 SEP y SEPB. Published by Elsevier España. All rights reserved.

Drug therapies against persistent human infections such as hepatitis C virus, hepatitis B virus, and HIV fail to consistently eradicate the infection from the host. Hence, recent emphasis has shifted to the study of antiviral therapy aimed at boosting specific immune responses. It was argued that structured therapy interruptions were required to achieve this, because such regimes have shown promising results in early HIV infection. Using mathematical models, we show that, contrary to this notion, a single phase of drug therapy can result in the establishment of sustained immunity. We present a simple relationship between timing of therapy and efficacy of the drugs required for success. In the presence of strong viral suppression, we show that therapy should be stopped relatively early, and that a longer duration of treatment leads to failure. On the other hand, in the presence of weaker viral suppression, stopping treatment too early is detrimental, and therapy has to be continued beyond a time threshold. We discuss our modeling results primarily in the context of HCV therapy during chronic infection. Although the therapy regimes explored here also have implications for HIV, virus-mediated destruction of specific immune cells renders success unlikely during the chronic phase of the infection.

In recent years drug prevention at the place of work has became increasingly important for programmes focussing on health promotion at the place of work. Drug prevention programmes aim at reducing cost and protecting the employees from physical harm. There are virtually no reliable figures from surveys in companies. To date intervention programme in companies have hardly been verified. In this feasibility study we intended to examine the practicability of an evaluation of an intervention programme in a large chemical company by means of questionnaires and we present preliminary intervention effects. In the context of a pilot study we conducted and evaluated a drug prevention programme at the place of work. Focus was on illegal designer drugs. The programme was conducted as a one-day workshop for trainers in superior management positions. We used a feedback form and a detailed questionnaire on drug prevention in the working place. 41 trainers who participated in the seminar were compared with a control group of 12 trainers who did not participate. The intervention programme was well accepted by the participants. Follow-up data demonstrated, that participants in the seminar had far better knowledge of the employment agreement on addiction and drugs and of the possible ways to get help and they were far more active in realising the employment agreement. To achieve a long-term improvement of drug abuse in companies it is not enough to include and implement a passage on drug abuse and addiction in the employment agreement. Well-instructed trainers talk far often with colleagues displaying abnormal or addictive behaviour, resulting in more rapid therapeutic interventions.

Early adolescent girls' rates of drug use have matched, and in some instances, surpassed boys' rates. Though girls and boys share risk factors for drug use, girls also have gender-specific risks. Tailored interventions to prevent girls' drug use are warranted. This study developed and tested a web-based, drug abuse prevention program for adolescent girls. The nationwide sample of 13- and 14-year-old girls (N = 788) was recruited via Facebook ads. Enrolled girls were randomly assigned to the intervention or control condition. All girls completed pretest measures online. Following pretest, intervention girls interacted with the 9-session, gender-specific prevention program online. The program aimed to reduce girls' drug use and associated risk factors by improving their cognitive and behavioral skills around such areas as coping with stress, managing mood, maintaining a healthy body image, and refusing drug use offers. Girls in both conditions again completed measures at posttest and 1-year follow-up. At posttest, and compared to girls in the control condition, girls who received the intervention smoked fewer cigarettes and reported higher self-esteem, goal setting, media literacy, and self-efficacy. At 1-year follow-up, and compared to girls in the control condition, girls who received the intervention reported engaging in less binge drinking and cigarette smoking; girls assigned to the intervention condition also had higher alcohol, cigarette, and marijuana refusal skills, coping skills, and media literacy and lower rates of peer drug use. This study's findings support the use of tailored, online drug abuse prevention programming for early adolescent girls.

Full Text Available Drug abuse is a problem that the population is highly sensitive. On the other hand, is clear that in the field of education, together with the family, the ideal roomto articulate prevention programmes. One the aspects which many educational programmes have not had the expec ted results has been for not taking into account the family environment and not control his influence. with this research we have found that there are significant differences in the 2nd ESO students attitude, regarding the rejection of tobacco, alcohol and other drugs, depending on which the prevention programme is aplied or not to students. Research has been done with quasi experimental pretest postest to not equivalent control group. The analysis of results, shows that the implementation of the programme has been effective as far as the students attitude has highly improved with regard to the prevention of drugs, mainly tobacco which is the most widely abused drug at these ages. Regarding the expected differences in students attitude by the implementation of a prevention programme with parents, we have not seen significant differences in the results possibly because the initial attitudes are very positive and is very short period of time. As a result of the study we believe it is important to recover the educator family role since its influence is decisive in prevention.

Rates of drug use among sexual-minority youths are disproportionately high. Yet, expressly designed prevention programs targeting this population are absent. This study developed and tested a web-based drug abuse prevention program for sexual-minority youths. A sample (N = 236) of sexual-minority youths was recruited via Facebook. Online, all youths completed pretests; youths randomly assigned to the intervention received a 3-session prevention program; and all youths completed posttest and 3-month follow-up measurements. At 3-month follow-up and compared to youths in the control arm, intervention-arm youths reported less stress, reduced peer drug use, lower rates of past 30-day other drug use, and higher coping, problem solving, and drug-use refusal skills. Outcome data suggest the potential of tailored intervention content to address sexual-minority youths' drug use rates and related risk factors. Moreover, study procedures lend support to the feasibility of using the Internet to recruit sexual-minority youths, collect data, and deliver intervention.

Full Text Available This review-type paper presents the latest knowledge on pheromone therapy. Pheromone therapy does not imply merely the use of structural analogues of pheromones in therapy, but also in the prevention of behavioral disorders in domestic animals. Their application is induced in all cases in which the effects of stressors are expected and their negative effect on the health condition, welfare and production results of domestic animals. Structural analogues of pheromones can successfully be applied in the prevention and therapy of behavioral disorders in horses, swine, dogs, and cats. Recent investigations have confirmed that structural analogues of semiochemicals exert a positive effect also on the production results and meat quality of broilers. They realize their therapeutic and preventive effect on the behavior of domestic animals through the stabilization of the emotional state, relaxation, and calming the animals that are disturbed, or could become disturbed due to the effect of stressors.
Full Text Available Five to ten million individuals are infected by Human T-cell Leukemia Virus type 1 (HTLV-1. HTLV-1 is transmitted through prolonged breast-feeding, by sexual contacts and by transmission of infected T lymphocytes through blood transfusion. One to ten percent of infected carriers will develop a severe HTLV-1-associated disease: Adult-T-cell leukemia/lymphoma (ATLL, or a neurological disorder named Tropical Spastic Paraparesis/HTLV-1 Associated Myelopathy (TSP/HAM. In vivo, HTLV-1 is mostly detected in CD4+ T-cells, and to a lesser extent in CD8+ T cells and dendritic cells. There is a strong correlation between HTLV-1 proviral load (PVL and clinical status of infected individuals. Thus, reducing PVL could be part of a strategy to prevent or treat HTLV-1-associated diseases among carriers. Treatment of ATLL patients using conventional chemotherapy has very limited benefit. Some chronic and acute ATLL patients are, however, efficiently treated with a combination of interferon α and zidovudine (IFN-α/AZT, to which arsenic trioxide is added in some cases. On the other hand, no efficient treatment for TSP/HAM patients has been described yet. It is therefore crucial to develop therapies that could either prevent the occurrence of HTLV-1-associated diseases or at least block the evolution of the disease in the early stages. In vivo, reverse transcriptase (RT activity is low in infected cells, which is correlated with a clonal mode of viral replication. This renders infected cells resistant to nucleoside RT inhibitors such as AZT. However, histone deacetylase inhibitors (HDACi associated to AZT efficiently induces viral expression and prevent de novo cellular infection. In asymptomatic STLV-1 infected non-human primates, HDACi/AZT combination allows a strong decrease in the PVL. Unfortunately, rebound in the PVL occurs when the treatment is stopped, highlighting the need for better antiviral compounds. Here, we review previously used strategies

To determine whether the presence of Clinical Pharmacist affects the cost of drug therapy for patients admitted to the Intensive Care Unit (ICU) at Al-Hussein hospital at Royal Medical Services in Amman, Jordan. This study compares the consumed quantities of drugs over two periods of time. Each period was ten months long. In the second period there was a Clinical Pharmacist. The decrease in consumption rate of drugs is considered to be an indicator of the success of Clinical Pharmacist in the ICU, as any decrease in consumption rate reflects the correct application of Clinical Pharmacy practices. The cost of this decrease in consumption rate represents the total reduction of drug therapy cost. The total reduction of drug therapy cost after applying Clinical Pharmacy practices in the ICU over a period of ten months was 149946.80 JD (211574.90 USD), which represents an average saving of 35.8% when compared to the first period in this study. The results of this study showed a significant reduction in the consumed quantities of drugs and therefore a reduction in cost of drug therapy. Such findings highlight the importance of the presence of Clinical Pharmacist in all Jordanian hospitals wards and units.

However, the rationale for formulating drugs at high drug loading in the same or separate fibers is unknown but has important implications for product development and clinical applications.Methods: Using a production-scale free-surface electrospinning instrument, we produced electrospun nanofibers with different microscale geometries for the co-delivery of tenofovir (TFV and levonorgestrel (LNG – two lead drug candidates for multipurpose prevention of HIV acquisition and unintended pregnancy. We investigated the in vitro drug release of TFV and LNG combinations from composites that deliver the two drugs from the same fiber (combined fibers or from separate fibers in a stacked or interwoven architecture. For stacked composites, we also examined the role that fabric thickness has on drug-release kinetics. We also measured the cytotoxicity and antiviral activity of the drugs delivered alone and in combination.Results: Herein, we report on the solution and processing parameters for the free-surface electrospinning of medical fabrics with controlled microarchitecture and high drug loading (up to 20 wt%. We observed that in vitro release of the highly water-soluble TFV, but not the water-insoluble LNG, was affected by composite microarchitecture, fabric thickness, and drug content. Finally, we showed that the drug-loaded nanofibers are noncytotoxic and that the antiviral activity of TFV is preserved through the electrospinning process and when combined with LNG.Conclusion: Electrospun fabrics with high drug loading create multicomponent systems that benefit from the independent control of the

The majority of opioid dependent patients suffer from various psychiatric and somatic comorbid diseases like mood and anxiety disorders, psychotic diseases, personality disorders, HIV infection, Hepatitis B and C. If medical treatment is needed, grouping active substances to FDA Pregnancy Categories (A, B, C, D or X) may be helpful. The majority of substances reported here only fulfill the FDA-categories C or D, which means that they could have teratogenic effects, but with probably different rank order. First of all, referring to mood, personality and anxiety disorders, the focus should be laid on non-pharmacological treatment by offering psychotherapeutic and supporting psychosocial interventions to the patients. However, opioid dependent pregnant patients who suffer from severe diseases such as psychosis, bipolar affective disorder or severe depression, may need psychoactive medication like antipsychotics, antidepressants or mood stabilizers to prevent them from harm caused by psychotic ideas and actions and/or suicidality. However these medications may comprise fetal risks, especially when taken together, and therefore should only be used when benefit and risks are considered together with patients and their relatives. It is important to avoid acute or renewed psychiatric decompensation. We present the current differentiated knowledge for therapy of opioid dependent patients with antipsychotics, antidepressants (e.g. higher fetal risk in case of treatment with fluoxetine and paroxetine) or mood stabilizers. All of them should only be used after considering benefit and risks. During pregnancy, there should not be switched between different antidepressant drugs. Referring mood stabilizers, the intake of valproic acid should be avoided in pregnancy or at least, dosage should be kept as low as possible since severe teratogenetic effects are known. In addition the specific drug treatment of HIV and hepatitis B during pregnancy is described. During childbirth HIV

Adverse drug events (ADEs) have been highlighted as a major patient safety and public health challenge by the National Action Plan for Adverse Drug Event Prevention (ADE Action Plan), which was released by the Office of Disease Prevention and Health Promotion (ODPHP) in August 2014. The ADE Action Plan focuses on surveillance, evidence-based prevention, incentives, and oversights, additional research needs as well as possible measures and metrics to track progress of ADE prevention within three drug classes: anticoagulants, diabetes agents, and opioids.Objectives and Recommendations. With outpatient opioid prescriptions being a great concern among many healthcare providers, this article focuses on recommendations from the ADE Action Plan to help guide safer opioid use in healthcare delivery settings. Its aim is to discuss current federal methods in place to prevent opioid ADEs while also providing evidence to encourage providers and hospitals to innovate new systems and practices to increase prevention.

Cardiovascular primary prevention and regeneration programs are the contemporary frontiers in functional metabolic vascular medicine. This novel science perspective harnesses our inherent ability to modulate the interface between specialized gene receptors and bioavailable nutrients in what is labeled as the nutrient-gene interaction. By mimicking a natural process through the conveyance of highly absorbable receptor specific nutrients, it is feasible to accelerate cell repair and optimize mitochondrial function, thereby achieving cardiovascular cure. We performed a comprehensive review of PubMed, EMBASE and Cochrane Review databases for articles relating to cardiovascular regenerative medicine, nutrigenomics and primary prevention, with the aim of harmonizing their roles within contemporary clinical practice. We searched in particular for large-scale randomized controlled trials on contemporary cardiovascular pharmacotherapies and their specific adverse effects on metabolic pathways which feature prominently in cardiovascular regenerative programs, such as nitric oxide and glucose metabolism. Scientific research on \\'cardiovascular-free\\' centenarians delineated that low sugar and low insulin are consistent findings. As we age, our insulin level increases. Those who can decelerate the rapidity of this process are prompting their cardiovascular rejuvenation. It is beginning to dawn on some clinicians that contemporary treatments are not only failing to impact on our most prevalent diseases, but they may be causing more damage than good. Primary prevention programs are crucial elements for a better outcome. Cardiovascular primary prevention and regeneration programs have enhanced clinical efficacy and quality of life and complement our conventional endovascular practice.

Hypercholesterolemia and hypertension are among the most important risk factors for cardiovascular (CV) disease. They are also important contributors to metabolic diseases including diabetes that further increase CV risk. Updated guidelines emphasize targeted reduction of overall CV risks but do not explicitly incorporate potential adverse metabolic outcomes that also influence CV health. Hypercholesterolemia and hypertension have synergistic deleterious effects on interrelated insulin resistance and endothelial dysfunction. Dysregulation of the renin-angiotensin system is an important pathophysiological mechanism linking insulin resistance and endothelial dysfunction to atherogenesis. Statins are the reference standard treatment to prevent CV disease in patients with hypercholesterolemia. Statins work best for secondary CV prevention. Unfortunately, most statin therapies dose-dependently cause insulin resistance, increase new onset diabetes risk and exacerbate existing type 2 diabetes mellitus. Pravastatin is often too weak to achieve target low-density lipoprotein cholesterol levels despite having beneficial metabolic actions. Renin-angiotensin system inhibitors improve both endothelial dysfunction and insulin resistance in addition to controlling blood pressure. In this regard, combined statin-based and renin-angiotensin system (RAS) inhibitor therapies demonstrate additive/synergistic beneficial effects on endothelial dysfunction, insulin resistance, and other metabolic parameters in addition to lowering both cholesterol levels and blood pressure. This combined therapy simultaneously reduces CV events when compared to either drug type used as monotherapy. This is mediated by both separate and interrelated mechanisms. Therefore, statin-based therapy combined with RAS inhibitors is important for developing optimal management strategies in patients with hypertension, hypercholesterolemia, diabetes, metabolic syndrome, or obesity. This combined therapy can help
Full Text Available Objective: The present study was designed to investigate the effectiveness of mindfulness in the prevention of relapse in drug abusers. Method: Using a quasi experimental design, 90 male drug abusers who had undergone detoxification were selected from among all detoxified individuals referred to drug rehabilitation centers in the City of Tehran. Patients were placed randomly in three groups: Mindfulness training intervention, behavioral drug reduction counseling and a control group in which no intervention was applied. Diagnosis of drug abuse was made using structured clinical interview for diagnosing axis I disorders on DSMIV (SCID-I as well as tests to measure morphine levels in the blood. Fisher test was used to compare groups. Patients were assessed two weeks and two months after the intervention as follow up measure. Findings: Results show that both intervention groups were effective in preventing relapse as compared to the control group. Furthermore, the effectiveness of mindfulness training and BDRC was about the same. There were no significant differences between patients with and without experience of drug abuse and married and single patients. Conclusion: Both mindfulness training and BDRC may be considered effective practical methods in reducing the risk of relapse in male drug abusers.

This research employed the theory of reasoned action to investigate the role of authoritative parenting in 3 drug-prevention behaviors: (a) parental monitoring, (b) parent-child discussions, and (c) awareness of the child's environment. A phone survey of 158 parents of adolescents in 7th, 9th, and 11th grades revealed that authoritative parenting was correlated with parenting practices that reduce the likelihood of adolescent drug use, including discussing family rules about drugs, discussing strategies to avoid drugs, discussing those in trouble with drugs, parental monitoring, knowing the child's plans for the coming day, and personally knowing the child's friends well. Additionally, authoritative parenting moderated the attitude-behavioral intention relation for parental monitoring and awareness of the child's environment, with the weakest relation detected for low-authoritative parents. The utility of these findings in helping design and target antidrug messages for parents more effectively is discussed.

Full Text Available ABSTRACT OBJECTIVE To analyze if characteristics of managers, schools, and curriculum are associated with the implementation of programs for drug abuse prevention in elementary and high schools. METHODS Cross-sectional study, with random sample of 263 school managers. Data were collected between 2012 and 2013 by a program that sends forms via internet. A closed self-filling questionnaire was applied online. Statistical analysis included Chi-square tests and logistic regression models. The outcome variable was the presence of program for drug abuse prevention inserted in the daily life and educational program of the school. The explanatory variables were divided into: demographic data of the manager; characteristics of the school and of the curriculum; health education; and drug use in the school. RESULTS We found that 42.5% (95%CI 36.1–49.1 of the evaluated schools had programs for drug abuse prevention. With the multiple logistic regression model, we observed that the more time the manager has worked with education, the chance of the school having a program increased at about 4.0%. Experimenting with innovative teaching techniques also increased at about six times the chance of the school developing a program for drug abuse prevention. The difficulties in the implementation of the programs were more present in state and municipal schools, when compared with private schools, due to, for instance: lack of teaching materials, lack of money, and competing demands for teaching other subjects. CONCLUSIONS The implementation of programs for drug abuse prevention in the city of Sao Paulo is associated with the experience of the manager in education and with the teaching strategies of the school.

An estimated 13 million youths aged 12 to 17 become involved with alcohol, tobacco and other drugs annually. The number of 12- to 17-year olds abusing controlled prescription drugs increased an alarming 212 percent between 1992 and 2003. For many youths, substance abuse precedes academic and health problems including lower grades, higher truancy, drop out decisions, delayed or damaged physical, cognitive, and emotional development, or a variety of other costly consequences. For thirty years the Narconon program has worked with schools and community groups providing single educational modules aimed at supplementing existing classroom-based prevention activities. In 2004, Narconon International developed a multi-module, universal prevention curriculum for high school ages based on drug abuse etiology, program quality management data, prevention theory and best practices. We review the curriculum and its rationale and test its ability to change drug use behavior, perceptions of risk/benefits, and general knowledge. After informed parental consent, approximately 1000 Oklahoma and Hawai'i high school students completed a modified Center for Substance Abuse Prevention (CSAP) Participant Outcome Measures for Discretionary Programs survey at three testing points: baseline, one month later, and six month follow-up. Schools assigned to experimental conditions scheduled the Narconon curriculum between the baseline and one-month follow-up test; schools in control conditions received drug education after the six-month follow-up. Student responses were analyzed controlling for baseline differences using analysis of covariance. At six month follow-up, youths who received the Narconon drug education curriculum showed reduced drug use compared with controls across all drug categories tested. The strongest effects were seen in all tobacco products and cigarette frequency followed by marijuana. There were also significant reductions measured for alcohol and amphetamines. The program

Anticancer therapy has always been a vital challenge for the development of nanomedicine. Repeated single therapeutic agent may lead to undesirable and severe side effects, unbearable toxicity and multidrug resistance due to complex nature of tumor. Nanomedicine-based combination anticancer therapy can synergistically improve antitumor outcomes through multiple-target therapy, decreasing the dose of each therapeutic agent and reducing side effects. There are versatile combinational anticancer strategies such as chemotherapeutic combination, nucleic acid-based co-delivery, intrinsic sensitive and extrinsic stimulus combinational patterns. Based on these combination strategies, various nanocarriers and drug delivery systems were engineered to carry out the efficient co-delivery of combined therapeutic agents for combination anticancer therapy. This review focused on illustrating nanomedicine-based combination anticancer therapy between nucleic acids and small-molecular drugs for synergistically improving anticancer efficacy.

Objective To describe access to antiepileptic drug therapy and estimate the prevalence of epilepsy in children in Camagüey Province, Cuba. Methods All the community pharmacies in the province were visited and information collected about the number of children receiving antiepileptic drugs in 2009. Availability and cost of each antiepileptic drug were determined. The prevalence of epilepsy was estimated by determining the number of children receiving antiepileptic drugs. Results There were 923 children who received a total of 977 antiepileptic drugs in Camagüey Province. The estimated prevalence of epilepsy was 5.18 per thousand children which is lower than previously reported rates in other low and lower-middle income countries. Most of the children (871, 94%) received a single antiepileptic drug. Carbamazepine and valproate were the two most frequently prescribed antiepileptic drugs. Antiepileptic drugs were available from the local pharmacy on 76% of occasions. If the antiepileptic drug was not available from the local pharmacy, the parent had to travel to another pharmacy to obtain the medicine. Conclusions The estimated prevalence of epilepsy in children in Cuba is lower than that estimated in other lower-middle income countries. Access to drug therapy in children with epilepsy can be achieved in lower-middle income countries. PMID:23134098
Full Text Available Abstract Background Preventive drugs require long-term trials to show their effectiveness or harms and often a lot of changes occur during post-marketing studies. The purpose of this article is to describe the research process in a long-term randomized controlled trial and discuss the impact and consequences of changes in the research environment. Methods The Estonian Postmenopausal Hormone Therapy trial (EPHT, originally planned to continue for five years, was planned in co-operation with the Women's International Study of Long-Duration Oestrogen after Menopause (WISDOM in the UK. In addition to health outcomes, EPHT was specifically designed to study the impact of postmenopausal hormone therapy (HT on health services utilization. Results After EPHT recruited in 1999–2001 the Women's Health Initiative (WHI in the USA decided to stop the estrogen-progestin trial after a mean of 5.2 years in July 2002 because of increased risk of breast cancer and later in 2004 the estrogen-only trial because HT increased the risk of stroke, decreased the risk of hip fracture, and did not affect coronary heart disease incidence. WISDOM was halted in autumn 2002. These decisions had a major influence on EPHT. Conclusion Changes in Estonian society challenged EPHT to find a balance between the needs of achieving responses to the trial aims with a limited budget and simultaneously maintaining the safety of trial participants. Flexibility was the main key for success. Rapid changes are not limited only to transiting societies but are true also in developed countries and the risk must be included in planning all long-term trials. The role of ethical and data monitoring committees in situations with emerging new data from other studies needs specification. Longer funding for preventive trials and more flexibility in budgeting are mandatory. Who should prove the effectiveness of an (old drug for a new preventive indication? In preventive drug trials companies may
A recent report from the Tuberculosis Chemotherapy Centre, Madras, showed that a vitamin-B-complex preparation containing a small amount of pyridoxine (as well as aneurine hydrochloride, riboflavine, nicotinamide, panthenol and cyanocobalamin) was effective in the treatment of peripheral neuropathy caused by daily high-dosage (12.5-15.2 mg/kg body-weight) isoniazid therapy of pulmonary tuberculosis. The present report gives results which show that the B-complex preparation is fully effective in preventing peripheral neuropathy in patients receiving the same high dosage of isoniazid, and that this is due to the small pyridoxine content of only 6 mg daily, and not to any of its other constituents. The low cost of this small dose of pyridoxine makes high-dosage isoniazid therapy, given in combination with other drugs or alone, a possible proposition in developing countries. Studies in the Centre have produced clear evidence that there is an increase in the frequency of peripheral neuropathy when the dosage of isoniazid is increased from 7.8-9.6 mg/kg body-weight to 12.5-15.6 mg/kg daily, and that its incidence is higher among slow than among rapid inactivators of isoniazid. The studies also show that increasing the dosage of isoniazid when given alone from a moderate daily dosage of 7.8-9.6 mg/kg to the high daily dosage of 12.5-15.6 mg/kg has not materially altered the radiographic or the bacteriological response to treatment.

Combination therapy for the treatment of cancer is becoming more popular because it generates synergistic anticancer effects, reduces individual drug-related toxicity and suppresses multi-drug resistance through different mechanisms of action. In recent years, nanotechnology-based combination drug delivery to tumor tissues has emerged as an effective strategy by overcoming many biological, biophysical and biomedical barriers that the body stages against successful delivery of anticancer drugs. The sustained, controlled and targeted delivery of chemotherapeutic drugs in a combination approach enhanced therapeutic anticancer effects with reduced drug-associated side effects. In this article, we have reviewed the scope of various nanotechnology-based combination drug delivery approaches and also summarized the current perspective and challenges facing the successful treatment of cancer.

Drug overdose is the most frequent cause of death among people who misuse illegal drugs. People who inject these drugs are 14-17 times more likely to die than their non-drug using peers. Various strategies to reduce drug-related deaths have failed to meet target reductions. Research into community-based interventions for preventing drug overdose deaths is promising. This review seeks to identify published studies describing community-based interventions and to evaluate their effectiveness at reducing drug overdose deaths. We will systematically search key electronic databases using a search strategy which groups terms into four facets: (1) Overdose event, (2) Drug classification, (3) Intervention and (4) Setting. Searches will be limited where possible to international literature published in English between 1998 and 2014. Data will be extracted by two independent reviewers using a predefined table adapted from the Cochrane Collaboration handbook. The quality of included studies will be evaluated using the Cochrane Collaboration's tool for assessing risk of bias. We will conduct a meta-analysis for variables which can be compared across studies, using statistical methods to control for heterogeneity where appropriate. Where clinical or statistical heterogeneity prevents a valid numerical synthesis, we will employ a narrative synthesis to describe community-based interventions, their delivery and use and how effectively they prevent fatal overdoses. We will publish findings from this systematic review in a peer-reviewed scientific journal and present results at national and international conferences. It will be disseminated electronically and in print. PROSPERO CRD42015017833. Published by the BMJ Publishing Group Limited.

Microtubule-targeting agents (MTAs), anticancer drugs widely used in the clinic, often induce peripheral neuropathy, a main dose-limiting side effect. The mechanism for this neurotoxicity remains poorly understood and there are still no approved therapies for neuropathies triggered by MTAs. Olesoxime (cholest-4-en-3-one, oxime; TRO19622) has shown marked neuroprotective properties in animals treated with paclitaxel and vincristine. The purpose of this study was to investigate its mechanism of neuroprotection against MTA neurotoxicity by using rat and human differentiated neuronal cells. We first showed that olesoxime prevented neurite shrinkage induced by MTAs in differentiated PC-12 and SK-N-SH neuroblastoma cell lines by up to 90%. This neuroprotective effect was correlated with enhanced EB1 accumulation at microtubule plus-ends, increased growth cone microtubule growing rate (20%) and decreased microtubule attenuation duration (54%). The effects of olesoxime on EB comets were specific for differentiated neuronal cells and were not seen either in proliferating neuroblastoma cells, glioblastoma cells or primary endothelial cells. Importantly, olesoxime did not alter MTA cytotoxic properties in a wide range of MTA-sensitive tumor cells, a prerequisite for future clinical application. Finally, olesoxime also counteracted MTA inhibition of microtubule-dependent mitochondria trafficking. These results provide additional insight into the neuroprotective properties of olesoxime, highlighting a role for microtubule dynamics in preservation of neurite architecture and axoplasmic transport, which are both disturbed by MTAs. The neuron-specific protective properties of olesoxime support its further development to treat MTA-induced neuropathy. Copyright 2010 Elsevier Inc. All rights reserved.

Implementation of therapeutic cancer prevention strategies has enormous potential for reducing cancer incidence and related mortality. Trials of drugs including tamoxifen and aspirin have led the way in demonstrating proof-of-principle that prevention of breast and colorectal cancer is feasible. Many other compounds ranging from drugs in widespread use for various indications, including metformin, bisphosphonates, and vitamin D, to dietary agents such as the phytochemicals resveratrol and curcumin, show preventive activity against several cancers in preclinical models. Notwithstanding the wealth of opportunities, major challenges have hindered the development process and only a handful of therapies are currently approved for cancer risk reduction. One of the major obstacles to successful clinical translation of promising preventive agents is a lack of pharmacodynamic biomarkers to provide an early read out of biological activity in humans and for optimising doses to take into large scale randomised clinical trials. A further confounding factor is a lack of consideration of clinical pharmacokinetics in the design of preclinical experiments, meaning results are frequently reported from studies that use irrelevant or unachievable concentrations. This article focuses on recent findings from investigations with dietary-derived agents to illustrate how a thorough understanding of the mechanisms of action, using models that mimic the clinical scenario, together with the development of compound-specific accompanying pharmacodynamic biomarkers could accelerate the developmental pipeline for preventive agents and maximise the chances of success in future clinical trials. Moreover, the concept of a bell-shaped dose-response curve for therapeutic cancer prevention is discussed, along with the need to rethink the traditional 'more is better' approach for dose selection.

β-Endorphin (BEP)-producing neuron in the hypothalamus plays a key role in bringing the stress axis to a state of homeostasis and maintaining body immune defense system. Long-term delivery of BEP to obtain beneficial effect on chemoprevention is challenging, as the peptides rapidly develop tolerance. Using rats as animal models, we show here that transplantation of BEP neurons into the hypothalamus suppressed carcinogens- and hormone-induced cancers in various tissues and prevented growth and metastasis of established tumors via activation of innate immune functions. In addition, we show that intracerebroventricular administration of nanosphere-attached dibutyryl cyclic adenosine monophosphate (dbcAMP) increased the number of BEP neurons in the hypothalamus, reduced the stress response, enhanced the innate immune function, and prevented tumor cell growth, progression, and metastasis. BEP neuronal supplementation did not produce any deleterious effects on general health but was beneficial in suppressing age-induced alterations in physical activity, metabolic, and immune functions. We conclude that the neuroimmune system has significant control over cancer growth and progression, and that activation of the neuroimmune system via BEP neuronal supplementation/induction may have therapeutic value for cancer prevention and improvement of general health. ©2014 American Association for Cancer Research.
Full Text Available Objective: We compared a three-drug combination therapy (control group consisting of tacrolimus, mycophenolate mofetil, and corticosteroids in living donor renal transplantation with a four-drug combination therapy (study group, in which the doses of tacrolimus and mycophenolate mofetil were halved and the immunosuppressive drug mizoribine was added, in order to determine whether the incidence rates of acute rejection after transplantation between the study group and the control group are similar, whether the study group regimen prevents the occurrence of calcineurin inhibitor–induced renal damage, and whether the study group regimen prevents adverse effects such as diarrhea caused by mycophenolate mofetil. Methods: We investigated the incidence of acute rejection, serum creatinine levels, and estimated glomerular filtration rate and the incidence of adverse effects such as diarrhea. Results: There was no significant difference between the two groups in the incidence of acute rejection. Renal function (estimated glomerular filtration rate and serum creatinine was maintained in the control group whereas in the study group renal function gradually improved, with a statistical difference observed at 12 months. The incidence of gastrointestinal symptoms including diarrhea was significantly higher in the control group than in the study group. There was no significant difference in the incidence of cytomegalovirus infection and other adverse effects. Conclusion: These results suggest the study group therapy is an effective regimen in preventing acute rejection and the deterioration of renal function. These results also show this therapy can reduce the incidence of adverse effects such as gastrointestinal symptoms.

Injection drug use has been identified as a key source of morbidity and mortality, primarily from overdose and the transmission of blood-borne diseases such as HIV. Experts have therefore called for the prioritization of resources toward the prevention of injection drug use. However, these strategies have not been systematically assessed. PRISMA guidelines were used to systematically review and extract findings from the peer-reviewed literature evaluating the effectiveness of interventions to prevent injecting initiation. We searched 10 English language electronic databases (PubMed, PsycINFO, EMBASE, Cochrane CENTRAL, CINAHL, Web of Science, TOXNET, AIDSLINE, AMED and ERIC), the Internet (Google, Google Scholar), and article reference lists, from database inception to June 1st, 2012. Overall, out of 384 studies identified in the initial search, eight met the inclusion criteria. Studies evaluated four different types of interventions: social marketing, peer-based behavior modification, treatment, and drug law enforcement. Four studies observed a significant effect of the intervention on reducing rates of injecting initiation. Peer-based behavior modification and addiction treatment interventions were found to be most effective. Two of three studies assessing the impact of drug law enforcement on patterns of injecting initiation found no impact on injecting initiation, while one study reported inconclusive results. There exists a limited scientific literature on strategies to prevent injecting initiation. Resources should be allocated toward increased research and development of effective interventions to prevent this phenomenon. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Local communities are increasingly targeted for alcohol and drug prevention campaigns. This study describes some of the key findings from the Swedish six-community alcohol and drug prevention trial (2003-2007) and lessons learned following an evaluation of the trial's effectiveness. The paper focuses mainly on changes in youth drinking and related harms. This was a pre- to post-intervention effect study comparing six trial communities that received added training and technical support with six control communities where regular prevention efforts were supported by national alcohol and drug action plans. A repeated, cross-sectional survey of 8092 youths aged 15-19 years assessed changes in alcohol consumption, binge drinking, perceived alcohol availability, access to alcohol via parents and adult attitudes towards the supply of alcohol to youths. National registry data were used to assess changes in hospital admissions due to alcohol intoxication. Overall, there were few significant improvements in the six trial communities compared with the control communities. The absence of program effects was largely attributable to the selection of strategies (in particular, school and parental programs) lacking evidence of effectiveness in reducing alcohol consumption at the aggregate level. Prevention programs based on efficacy studies need to be tested in community-based effectiveness trials before being disseminated. © 2013 Australasian Professional Society on Alcohol and other Drugs.

To determine compliance and factors affecting compliance to antiresorptive drugs in osteoporosis, and to compare compliant and non compliant groups in a tertiary care setting. A total of 800 patients with postmenopausal osteoporosis were included in the study. The demographic and reproductive characteristics of all the patients were recorded. Type of antiresorptive drugs prescribed, degree of compliance, time and reasons for discontinuation were studied and analyzed. The mean age of the patients was 64 (+-9) years and their mean duration of follow-up 18 (+-5) months. The prevalence of risk factors for osteoporosis were evenly distributed among treatment groups; 73% patients had a co-morbidity besides osteoporosis while 27% were osteoporotic alone. One or more previous vertebral fractures due to osteoporosis was reported by 14.5% of patients, whereas 35.5% had at least one non-vertebral fracture in their medical history. Out of the total patients 21.5% discontinued the prescribed drug before attending the bone mass re-evaluations, more than half of these within first six months of starting the drugs. The medication that was most frequently discontinued within one year was calcium and vitamin-D (33.7%, p<0.01) while the least discontinued medication was Alendronate (5.9%, p < 0.01) which is taken once a week. In this study the most important determinant of compliance was the type of drug prescribed and its dose frequency, with a definite preference for Alendronate once a week. Treatment compliance was particularly poor for calcium and vitamin-D regimen, thereby emphasizing the need to find new ways of administering supplements, particularly for vitamin-D. (author)

Drug errors are quite common. Many of them become harmful only if they remain undetected, ultimately resulting in injury to the patient. Errors with cytotoxic drugs are especially dangerous because of the highly toxic potential of the drugs involved. For medico-legal reasons, only 1 case of accidental iatrogenic intoxication by cytotoxic drugs tends to be investigated at a time, because the focus is placed on individual responsibility rather than on system errors. The aim of our study was to investigate whether accidental iatrogenic intoxications by cytotoxic drugs are faults of either the individual or the system. The statistical analysis of distribution and quality of such errors, and the in-depth analysis of contributing factors delivered a rational basis for the development of practical preventive strategies. A total of 134 cases of accidental iatrogenic intoxication by a cytotoxic drug (from literature reports since 1966 identified by an electronic literature survey, as well as our own unpublished cases) underwent a systematic error analysis based on a 2-dimensional model of error generation. Incidents were classified by error characteristics and point in time of occurrence, and their distribution was statistically evaluated. The theories of error research, informatics, sensory physiology, cognitive psychology, occupational medicine and management have helped to classify and depict potential sources of error as well as reveal clues for error prevention. Monocausal errors were the exception. In the majority of cases, a confluence of unfavourable circumstances either brought about the error, or prevented its timely interception. Most cases with a fatal outcome involved erroneous drug administration. Object-inherent factors were the predominant causes. A lack of expert as well as general knowledge was a contributing element. In error detection and prevention of error sequelae, supervision and back-checking are essential. Improvement of both the individual

We review the historical regulation of drug compounding, concerns about widespread use of non-Food and Drug Admiistration (FDA)-approved compounded bioidentical hormone therapies (CBHTs), which do not have proper labeling and warnings, and anticipated impact of the 2013 Drug Quality and Security Act (DQSA) on compounding. US government websites were searched for documents concerning drug compounding regulation and oversight from 1938 (passage of Federal Food, Drug, and Cosmetic Act [FDCA]) through 2014, including chronologies, Congressional testimony, FDA guidelines and enforcements, and reports. The FDCA and DQSA were reviewed. PubMed and Google were searched for articles on compounded drugs, including CBHT. Congress explicitly granted the FDA limited oversight of compounded drugs in a 1997 amendment to the FDCA, but the FDA has encountered obstacles in exercising that authority. After 64 patient deaths and 750 adversely affected patients from the 2012 meningitis outbreak due to contaminated compounded steroid injections, Congress passed the DQSA, authorizing the FDA to create a voluntary registration for facilities that manufacture and distribute sterile compounded drugs in bulk and reinforcing FDCA regulations for traditional compounding. Given history and current environment, concerns remain about CBHT product regulation and their lack of safety and efficacy data. The DQSA and its reinforcement of §503A of the FDCA solidifies FDA authority to enforce FDCA provisions against compounders of CBHT. The new law may improve compliance and accreditation by the compounding industry; support state and FDA oversight; and prevent the distribution of misbranded, adulterated, or inconsistently compounded medications, and false and misleading claims, thus reducing public health risk.

HIV infection still has a serious health and socio-economical impact and is one of the primary causes of morbidity and mortality all over the world. HIV infection and the AIDS pandemic are still matters of great concern, especially in less developed countries where the access to highly active antiretroviral therapy (HAART) is limited. Patient compliance is another serious drawback. Nowadays, HAART is the treatment of choice although it is not the panacea. Despite the fact that it suppresses viral replication at undetectable viral loads and prevents progression of HIV infection into AIDS HAART has several pitfalls, namely, long-term side-effects, drug resistance development, emergence of drug-resistant viruses, low compliance and the intolerance of some patients to these drugs. Moreover, another serious health concern is the event of co-infection with more than one pathogen at the same time (e.g. HIV and HCV, HBV, herpes viruses, etc). Currently, the multi-target drug approach has become an exciting strategy to address complex diseases and overcome drug resistance development. Such multifunctional molecules combine in their structure pharmacophores that may simultaneously interfere with multiple targets and their use may eventually be more safe and efficacious than that involving a mixture of separate molecules because of avoidance or delay of drug resistance, lower incidence of unwanted drug-drug interactions and improved compliance. In this review we focus on multifunctional molecules with dual activity against different targets of the HIV life cycle or able to block replication, not only of HIV but also of other viruses that are often co-pathogens of HIV. The different approaches are documented by selected examples. Copyright © 2018 The Authors. Published by Elsevier Masson SAS.. All rights reserved.
Full Text Available Nicolás E Quintana,* Alejandro R Allocco,* Julia A Ponce,* Mauricio GB Magurno Instituto Santa Lucía, Paraná, Argentina *These authors contributed equally to this work Background: Cystoid macular edema (CME remains an important complication after cataract surgery. There is no consensus about how to prevent this frequent complication. The purpose of this study was to conceive an effective anti-inflammatory strategy using nonsteroidal anti-inflammatory drugs (NSAIDs together with regular treatment with corticosteroids to prevent CME and improve visual acuity after cataract surgery in patients without risk factors. Materials and methods: We searched the PubMed, Cochrane, and Google Scholar databases focused on prospective, controlled, randomized, double-blind clinical trials published in the last 10 years, with a minimum follow-up of 4 weeks. Results: A total of nine clinical trials, one systematic review, and two reviews satisfied our search criteria. Most studies highlighted that NSAIDs are as powerful as corticosteroids to diminish postoperative inflammation, and demonstrated an additional benefit when used in combination with standard corticosteroid postsurgical therapy. In addition, the use of NSAIDs in the perioperative period seems to significantly improve the outcome after surgery and helps prevent CME in low-risk patients. Conclusion: The prophylactic use of NSAIDs in combination with the standard postoperative steroid scheme appears to be a positive course of action for preventing CME after cataract surgery. We suggest a therapeutic scheme based on the administration of one drop four times a day, beginning the day before surgery and for 4 weeks after the procedure. It is also advisable to administer one drop every 15 minutes in the hour prior to surgery in order to obtain better anti-inflammatory efficacy.

BACKGROUND: Owing to increasing sulfadoxine-pyrimethamine (SP) resistance in sub-Saharan Africa, monitoring the effectiveness of intermittent preventive therapy in pregnancy (IPTp) with SP is crucial. METHODS: Between 2009 and 2013, both the efficacy of IPTp-SP at clearing existing peripheral...... malaria infections and the effectiveness of IPTp-SP at reducing low birth weight (LBW) were assessed among human immunodeficiency virus-uninfected participants in 8 sites in 6 countries. Sites were classified as high, medium, or low resistance after measuring parasite mutations conferring SP resistance......, in these high-resistance areas, IPTp-SP use remains associated with increases in birth weight and maternal hemoglobin. The effectiveness of IPTp in eastern and southern Africa is threatened by further increases in SP resistance and reinforces the need to evaluate alternative drugs and strategies for the control...

Previous attempts to review the literature on magnetic nanomaterials for hyperthermia-based therapy focused primarily on magnetic fluid hyperthermia (MFH) using mono metallic/metal oxide nanoparticles. The term "hyperthermia" in the literature was also confined only to include use of heat for therapeutic applications. Recently, there have been a number of publications demonstrating magnetic nanoparticle-based hyperthermia to generate local heat resulting in the release of drugs either bound to the magnetic nanoparticle or encapsulated within polymeric matrices. In this review article, we present a case for broadening the meaning of the term "hyperthermia" by including thermotherapy as well as magnetically modulated controlled drug delivery. We provide a classification for controlled drug delivery using hyperthermia: Hyperthermia-based controlled drug delivery through bond breaking (DBB) and hyperthermia-based controlled drug delivery through enhanced permeability (DEP). The review also covers, for the first time, core-shell type magnetic nanomaterials, especially nanoshells prepared using layer-by-layer self-assembly, for the application of hyperthermia-based therapy and controlled drug delivery. The highlight of the review article is to portray potential opportunities for the combination of hyperthermia-based therapy and controlled drug release paradigms--towards successful application in personalized medicine.

The maladaptive drug memory developed between the drug-rewarding effect and environmental cues contributes to difficulty in preventing drug relapse. Established reward memories can be disrupted by pharmacologic interventions following their reactivation. Rapamycin, an inhibitor of mammalian target of rapamycin (mTOR) kinase, has been proved to be involved in various memory consolidation. However, it is less well characterized in drug memory reconsolidation. Using a conditioned place preference (CPP) procedure, we examined the effects of systemically administered rapamycin on reconsolidation of drug memory in rats. We found that systemically administered rapamycin (0.1 or 10 mg/kg, i.p.) after re-exposure to drug-paired environment, dose dependently decreased the expression of CPP 1 d later, and the effect lasted for up to 14 d and could not be reversed by a priming injection of morphine. The effect of rapamycin on morphine-associated memory was specific to drug-paired context, and rapamycin had no effect on subsequent CPP expression when rats were exposed to saline-paired context or homecage. These results indicated that systemic administration of rapamycin after memory reactivation can persistently inhibit the drug seeking behaviour via disruption of morphine memory reconsolidation in rats. Additionally, the effect of rapamycin on memory reconsolidation was reproduced in cocaine CPP and alcohol CPP. Furthermore, rapamycin did not induce conditioned place aversion and had no effect on locomotor activity and anxiety behaviour. These findings suggest that rapamycin could erase the acquired drug CPP in rats, and that mTOR activity plays an important role in drug reconsolidation and is required for drug relapse.

Oxidant stress in the cardiovascular system may occur when antioxidant capacity is insufficient to reduce reactive oxygen species and other free radicals. Oxidant stress has been linked to the pathogenesis of atherosclerosis and incident coronary artery disease. As a result of this connection, early observational studies focused on dietary antioxidants, such as β-carotene, α-tocopherol, and ascorbic acid, and demonstrated an inverse relationship between intake of these antioxidants and major adverse cardiovascular events. These findings supported a number of randomized trials of selected antioxidants as primary and secondary prevention to decrease cardiac risk; however, many of these studies reported disappointing results with little or no observed risk reduction in antioxidant treated patients. Several plausible explanations for these findings have been suggested, including incorrect antioxidant choice or dose, synthetic versus dietary antioxidant as the intervention, and patient selection, all of which will be important to consider when designing future clinical trials. This review will focus on the contemporary evidence that is the basis for our current understanding of the role of antioxidants in cardiovascular disease prevention. PMID:25369999

The population of the world is aging. A greater proportion of older people are retaining increasing numbers of natural teeth. Aging is associated with changes in oral architecture and muscle weakness, making personal oral hygiene more difficult, particularly for the oldest and most frail individuals. Furthermore, there is exposure of root dentin with its higher pH for demineralization in addition to enamel as a substrate for caries. Aging is also associated, for many in the developed world, with taking multiple medications, with the associated risk of dry mouth. These variables combine to increase caries risk in older vulnerable populations. Caries occurs on both the crowns of teeth (predominantly around existing restorations) and the exposed roots. Prevention needs to be aggressive to control disease in this combination of circumstances, with multiple strategies for limiting the damage associated with caries in this population. This paper explores the evidence that is available supporting preventive strategies, including fluorides in various forms, chlorhexidine, and calcium phosphate supplementation.

Chlorine (Cl 2 ) gas exposure and toxicity remains a concern in military and industrial sectors. While post-Cl 2 exposure damage to the lungs and other tissues has been documented and major underlying mechanisms elucidated, no targeted therapeutics that are effective when administered post-exposure, and which are amenable to mass-casualty scenarios have been developed. Our recent studies show nitrite administered by intramuscular (IM) injection post-Cl 2 exposure is effective in preventing acute lung injury and improving survival in rodent models. Our goal in this study was to develop a rabbit model of Cl 2 toxicity and test whether nitrite affords protection in a non-rodent model. Exposure of New Zealand White rabbits to Cl 2 gas (600ppm, 45min) caused significant increases in protein and neutrophil accumulation in the airways and ∼35% mortality over 18h. Nitrite administered 30min post Cl 2 exposure by a single IM injection, at 1mg/kg or 10mg/kg, prevented indices of acute lung injury at 6h by up to 50%. Moreover, all rabbits that received nitrite survived over the study period. These data provide further rationale for developing nitrite as post-exposure therapeutic to mitigate against Cl 2 gas exposure injury. Copyright © 2017 Elsevier B.V. All rights reserved.

Carbon nanotubes (CNTs) were discovered in 1991 and shown to have certain unique physicochemical properties, attracting considerable interest in their application in various fields including drug delivery. The unique properties of CNTs such as ease of cellular uptake, high drug loading, thermal ablation, among others, render them useful for cancer therapy. Cancer is one of the most challenging diseases of modern times because its therapy involves distinguishing normal healthy cells from affected cells. Here, CNTs play a major role because phenomena such as EPR, allow CNTs to distinguish normal cells from affected ones, the Holy Grail in cancer therapy. Considerable work has been done on CNTs as drug delivery systems over the last two decades. However, concerns over certain issues such as biocompatibility and toxicity have been raised and warrant extensive research in this field. (author)

In this paper we analyse some ethical and philosophical questions related to the development of memory enhancing drugs (MEDs) and anti-dementia drugs. The world of memory enhancement is coloured by utopian thinking and by the desire for quicker, sharper, and more reliable memories. Dementia is characterized by decline, fragility, vulnerability, a loss of the most important cognitive functions and even a loss of self. While MEDs are being developed for self-improvement, in Alzheimer's Disease (AD) the self is being lost. Despite this it is precisely those patients with AD and other forms of dementia that provide the subjects for scientific research on memory improvement. Biomedical research in the field of MEDs and anti-dementia drugs appears to provide a strong impetus for rethinking what we mean by 'memory', 'enhancement', 'therapy', and 'self'. We conclude (1) that the enhancement of memory is still in its infancy, (2) that current MEDs and anti-dementia drugs are at best partially and minimally effective under specific conditions, (3) that 'memory' and 'enhancement' are ambiguous terms, (4) that there is no clear-cut distinction between enhancement and therapy, and (5) that the research into MEDs and anti-dementia drugs encourages a reductionistic view of the human mind and of the self.

Purpose: In proton therapy, collisions between the patient and nozzle potentially occur because of the large nozzle structure and efforts to minimize the air gap. Thus, software was developed to predict such collisions between the nozzle and patient using treatment virtual simulation. Methods: Three-dimensional (3D) modeling of a gantry inner-floor, nozzle, and robotic-couch was performed using SolidWorks based on the manufacturer’s machine data. To obtain patient body information, a 3D-scanner was utilized right before CT scanning. Using the acquired images, a 3D-image of the patient’s body contour was reconstructed. The accuracy of the image was confirmed against the CT image of a humanoid phantom. The machine components and the virtual patient were combined on the treatment-room coordinate system, resulting in a virtual simulator. The simulator simulated the motion of its components such as rotation and translation of the gantry, nozzle, and couch in real scale. A collision, if any, was examined both in static and dynamic modes. The static mode assessed collisions only at fixed positions of the machine’s components, while the dynamic mode operated any time a component was in motion. A collision was identified if any voxels of two components, e.g., the nozzle and the patient or couch, overlapped when calculating volume locations. The event and collision point were visualized, and collision volumes were reported. Results: All components were successfully assembled, and the motions were accurately controlled. The 3D-shape of the phantom agreed with CT images within a deviation of 2 mm. Collision situations were simulated within minutes, and the results were displayed and reported. Conclusions: The developed software will be useful in improving patient safety and clinical efficiency of proton therapy.

Alzheimer's disease, cerebrovascular disease and aging-related cognitive impairment and dementia (ARCID) increase in prevalence in women with advancing age. The development of Alzheimer's disease, cerebrovascular disease and ARCID may be postponed or prevented by protective measures including the active treatment of vascular risk factors and continuing exercise and healthy lifestyle from early- and mid-life onward. Bilateral oophorectomy before the natural menopause is associated with an increased incidence of ARCID and the increased risk is significantly reduced by estrogen therapy. Recent advances in menopause hormone therapy including transdermal estrogen therapy have favorably influenced the balance of benefits and risks. A case can be made for menopause hormone therapy in healthy postmenopausal women for 5-10 years starting during the menopausal transition (the 'window of opportunity'), together with all other protective measures, to delay or prevent the development of ARCID in later life.

This paper studies the dynamics of the hepatitis B virus (HBV) model and the therapy regimens of HBV disease. First, we propose a new mathematical model of HBV with drug resistance, and then analyze its qualitative and dynamical properties. Combining the clinical data and theoretical analysis, we demonstrate that our model is biologically plausible and also computationally viable. Second, we demonstrate that the intermittent antiviral therapy regimen is one of the possible strategies to treat this kind of complex disease. There are two main advantages of this regimen, i.e. it not only may delay the development of drug resistance, but also may reduce the duration of on-treatment time compared with the long-term continuous medication. Moreover, such an intermittent antiviral therapy can reduce the adverse side effects. Our theoretical model and computational results provide qualitative insight into the progression of HBV, and also a possible new therapy for HBV disease.

Opioid substitution therapy (OST) is an evidence-based HIV prevention strategy for people who inject drugs (PWIDs). Yet, only 2.7% of Ukraine's estimated 310,000 PWIDs receive it despite free treatment since 2004. The multi-level barriers to entering OST among opioid dependent PWIDs have not been examined in Ukraine. A multi-year mixed methods implementation science project included focus group discussions with 199 PWIDs in 5 major Ukrainian cities in 2013 covering drug treatment attitudes and beliefs and knowledge of and experiences with OST. Data were transcribed, translated into English and coded. Coded segments related to OST access, entry, knowledge, beliefs and attitudes were analyzed among 41 PWIDs who were eligible for but had never received OST. A number of programmatic and structural barriers were mentioned by participants as barriers to entry to OST, including compulsory drug user registration, waiting lists, and limited number of treatment slots. Participants also voiced strong negative attitudes and beliefs about OST, especially methadone. Their perceptions about methadone's side effects as well as the stigma of being a methadone client were expressed as obstacles to treatment. Despite expressed interest in treatment, Ukrainian OST-naïve PWIDs evade OST for reasons that can be addressed through changes in program-level and governmental policies and social-marketing campaigns. Voiced OST barriers can effectively inform public health and policy directives related to HIV prevention and treatment in Ukraine to improve evidence-based treatment access and availability.

Background There are different treatment options for ocular toxoplasmosis (OT). "Classic" therapy consists of pyrimethamine, sulfadiazine and folinic acid combined with systemic steroids and is still widely used. However, potentially severe side effects of this therapy have been reported. The aim of this retrospective study was to evaluate the incidence and types of adverse drug reactions in patients treated for OT. Clinical management of each adverse drug reaction was assessed. Patients and Methods In this retrospective analysis, we reviewed data of patients with OT, who were consecutively examined between December 2011 and December 2015 at the Department of Ophthalmology, University Hospital Zurich. Results In total, 49 patients had at least one episode of active OT. In 54 (83.0 %) of 65 treated episodes, the classic regimen was used. Of the 37 patients who received classic treatment, 9 (24.3 %) developed at least one adverse drug reaction which led to drug discontinuation, including elevated creatinine (5.4 %), elevated liver enzymes (5.4 %), vomiting (5.4 %), rash (5.4 %) and facial swelling (2.7 %). In 5 patients, treatment was switched to another drug, while in the other 4 patients, therapy was stopped. In these 9 patients, inflammation was well controlled 8 weeks after onset of therapy. No patient suffered from severe side effects, such as potentially life-threatening allergic reactions or pancytopenia. Conclusions In OT patients who were treated with classic therapy, adverse drug reactions are common. Therefore, clinical and laboratory monitoring is mandatory. Adverse drug reactions may require interdisciplinary management. Georg Thieme Verlag KG Stuttgart · New York.
Full Text Available Nanoparticles combined with cells, drugs, and specially designed genes provide improved therapeutic efficacy in studies and clinical setting, demonstrating a new era of treatment strategy, especially in retinal diseases. Nanotechnology-based drugs can provide an essential platform for sustaining, releasing and a specific targeting design to treat retinal diseases. Poly-lactic-co-glycolic acid is the most widely used biocompatible and biodegradable polymer approved by the Food and Drug Administration. Many studies have attempted to develop special devices for delivering small-molecule drugs, proteins, and other macromolecules consistently and slowly. In this article, we first review current progress in the treatment of age-related macular degeneration. Then, we discuss the function of vascular endothelial growth factor (VEGF and the pharmacological effects of anti-VEGF-A antibodies and soluble or modified VEGF receptors. Lastly, we summarize the combination of antiangiogenic therapy and nanomedicines, and review current potential targeting therapy in age-related macular degeneration.

Use of alcohol and other illicit drugs by adolescent male athletes is a significant problem. Participation in sports may encourage use of drugs that enhance athletic performance, especially anabolic steroids (AS). Because, to our knowledge, no other intervention has successfully altered substance abuse by athletes, we developed and assessed the efficacy of a team-centered, sex-specific education program designed to reduce adolescent athletes' intentions to use and use of AS and alcohol and other illicit drugs. We studied 31 high school football teams that comprised 3207 athletes in 3 successive annual cohorts (1994-1996). The intervention included interactive classroom and exercise training sessions given by peer educators and facilitated by coaches and strength trainers. Program content included discussion of sports nutrition, exercise alternatives to AS and sport supplements, and the effects of substance abuse in sports, drug refusal role-playing, and the creation of health promotion messages. Questionnaires assessing AS, the use of sport supplements and alcohol and other illicit drugs, and potential risk and protective factors were administered before and after the intervention (before and after the football season) and up to 1 year after the program. At season's end, intentions to use (PIllicit drug use (marijuana, amphetamines, and narcotics) was reduced at 1 year, whether alcohol was included (P = .04) or excluded (P = .02) from the index. Other long-term effects included fewer students reporting drinking and driving (P = .004), less sport supplement use (P = .009), and improved nutrition behaviors (Pillicit drugs and associated harmful activities can be prevented with a sex-specific, team-centered education. School athletic teams provide an optimal environment in which to provide drug prevention and health promotion education.

Recent advances in biotechnology have led to discoveries resulting in major improvements in the therapy of refractory malignancies, although most advanced cancers remain incurable. Thus, there is global consensus around the need to streamline the drug approval process for effective agents. Accelerated Approval and Breakthrough Therapy Designation hold the promise of making new treatments available sooner through the use of smaller studies using intermediate endpoints. Here, we consider the inherent limitations of smaller studies and discuss the strategies for hastening oncology drug development while maintaining high-efficacy standards. ©2013 AACR.

Lanthanide-doped upconverting luminescent nanoparticles (UCNPs) are promising materials for optical imaging-guided drug delivery and therapy due to their unique optical and chemical properties. UCNPs absorb low energy near-infrared (NIR) light and emit high-energy shorter wavelength photons. Their special features allow them to overcome various problems associated with conventional imaging probes and to provide versatility for creating nanoplatforms with both imaging and therapeutic modalities. Here, we discuss several approaches to fabricate and utilize UCNPs for traceable drug delivery and therapy. Published by Elsevier B.V.
Full Text Available Photodynamic therapy (PDT has already been a multifunctional modality for various tumors and nontumorous diseases. However, the development of photosensitizers is relatively delayed, compared with the tremendous progress in laser technology. Elsinochrome A (EA, a perylenequinonoid pigment from China, has all the typical advantages of perylenequinones. Moreover, singlet oxygen quantum yield of EA is superior to other kinds of photosensitizers and EA could be artificially biosynthesized at present, which make it an alternative candidate for PDT. In this review, the photophysics, photochemistry, photobiology and chemical or biological syntheses of EA photosensitizers are briefly presented. Besides, the future prospects of EA photosensitizers are also proposed.
Full Text Available Multiple myeloma (MM remains incurable despite important recent advances in treatment. Over the last 2 years, an anti-CD38 monoclonal antibody daratumumab (DARA has emerged as a breakthrough targeted therapy for patients with MM. Early-stage clinical trials have found DARA to be safe and to have encouraging clinical activity as a single agent and in combination with lenalidomide in heavily pretreated, relapsed patients in whom other novel agents (such as bortezomib, thalidomide and lenalidomide as well as stem cell transplant has already failed. This review discusses the preclinical and clinical development of DARA, its pathophysiological basis, and its prospects for future use in MM.

One of the most significant health problems in the American continent in terms of human health, and socioeconomic impact is Chagas disease, caused by the protozoan parasite Trypanosoma cruzi. Infection was originally transmitted by reduviid insects, congenitally from mother to fetus, and by oral ingestion in sylvatic/rural environments, but blood transfusions, organ transplants, laboratory accidents, and sharing of contaminated syringes also contribute to modern day transmission. Likewise, Chagas disease used to be endemic from Northern Mexico to Argentina, but migrations have earned it global. The parasite has a complex life cycle, infecting different species, and invading a variety of cells - including muscle and nerve cells of the heart and gastrointestinal tract - in the mammalian host. Human infection outcome is a potentially fatal cardiomyopathy, and gastrointestinal tract lesions. In absence of a vaccine, vector control and treatment of patients are the only tools to control the disease. Unfortunately, the only drugs now available for Chagas' disease, Nifurtimox and Benznidazole, are relatively toxic for adult patients, and require prolonged administration. Benznidazole is the first choice for Chagas disease treatment due to its lower side effects than Nifurtimox. However, different strategies are being sought to overcome Benznidazole's toxicity including shorter or intermittent administration schedules-either alone or in combination with other drugs. In addition, a long list of compounds has shown trypanocidal activity, ranging from natural products to specially designed molecules, re-purposing drugs commercialized to treat other maladies, and homeopathy. In the present review, we will briefly summarize the upturns of current treatment of Chagas disease, discuss the increment on research and scientific publications about this topic, and give an overview of the state-of-the-art research aiming to produce an alternative medication to treat T. cruzi infection

Immobility is associated with complications involving many body systems. To review the effect of rotational therapy (use of therapeutic surfaces that turn on their longitudinal axes) on prevention and/or treatment of respiratory complications in critically ill patients. Published articles evaluating prophylaxis and/or treatment were reviewed. Prospective randomized controlled trials were assessed for quality and included in meta-analyses. A literature search yielded 15 nonrandomized, uncontrolled, or retrospective studies. Twenty prospective randomized controlled trials on rotational therapy were published between 1987 and 2004. Various types of beds were studied, but few details on the rotational parameters were reported. The usual control was manual turning of patients by nurses every 2 hours. One animal investigation and 12 clinical trials addressed the effectiveness of rotational therapy in preventing respiratory complications. Significant benefits were reported in the animal study and 4 of the trials. Significant benefits to patients were reported in 2 of another 4 studies focused on treatment of established complications. Researchers have examined the effects of rotational therapy on mucus transport, intrapulmonary shunt, hemodynamic effects, urine output, and intracranial pressure. Little convincing evidence is available, however, on the most effective rotation parameters (eg, degree, pause time, and amount of time per day). Meta-analysis suggests that rotational therapy decreases the incidence of pneumonia but has no effect on duration of mechanical ventilation, number of days in intensive care, or hospital mortality. Rotational therapy may be useful for preventing and treating respiratory complications in selected critically ill patients receiving mechanical ventilation.
Full Text Available Dolutegravir (DTG is a second-generation integrase strand transfer inhibitor (INSTI and INSTIs are the latest class of potent anti-HIV drugs. Compared to the first generation INSTIs, raltegravir (RAL and elvitegravir (EVG, DTG shows a limited cross-resistance profile. More interestingly, clinical resistance mutations to DTG in treatment-naive patents have not been observed to this date. This review summarizes recent studies on resistance mutations to DTG and on our understanding of the mechanisms of resistance to DTG as well as future directions for research.
The prognosis and treatment outcome for primary brain tumors have remained unchanged despite advances in anticancer drug discovery and development.

Full Text Available Introduction & Objective: Drug abuse is one of the complicated phenomenons in the human communities that it produces health problems. The effect of applying fear appeal message on attitudes and intention against drug abuse, drug resistance skills, knowledge about side effect of drugs and drug abuse related behaviors among male high school students was studied based on applying extended parallel process model as a theoretical framework. Materials & Methods: Two high schools were chosen from six state high schools as an intervention (n=86 and control (n=97 groups. Educational curriculum, that was designed, based on students’ educational needs, appealed students’ fear and recommended messages developed students' ability for resisting against drugs. Before intervention 5-6 students who were known as a favourite and leader of students, were selected by student’s opinion in each class as students' leaders. The each leader of the group had a coordinator and mediate role between his group and health educators. Henceforth a favourite teacher was chosen by students’ vote for helping health educators and participated in the educational intervention program.Results: The result showed that educational manipulation had significant effect on intervention group’s average response for intention (t= -4.03, p<0.000 and attitude against drug abuse (t= -6.19, p<0.000, peer resistance skills (t=-0.82, p<0.000, and knowledge (t= -10.88, p<0.000. In addition, it was not found positive urinary rapid immune-chromatography test for opium and marijuana in the intervention group whereas 6.3% in the control groups.Conclusion: This findings suggest that applying fear appeals theories and effective health risk message would be an efficient tool for preventing drug abuse education programs but further studies are needed to define function of EPPM as a effective model for creating social inoculation against drug abuse among non- drug expose adolescents.

Most Brazilian schools do not have a continuous program for drug use prevention and do not conduct culturally adapted activities for that purpose. This study evaluated the impact of the Unplugged program on drug use prevention among children and adolescents in public middle schools of Brazil. A non-randomized controlled trial was conducted in 2013 with 2185 students in 16 public schools from 3 Brazilian cities. The intervention group attended 12 weekly classes of the Unplugged program for drug use prevention, and the control group did not attend to any school prevention programs in the same year. Multilevel analyses were used to evaluate temporal and between group changes in the consumption of each drug. The study suggested that there was no evidence that Unplugged effected 11- to 12-year-old students. However, the program seemed to stimulate a decrease in recent marijuana use (transition from use to non-use in 85.7% of intervention cases and 28.6% of control cases, OR = 17.5, p = 0.039) among 13- to 15-year-old students. In addition, students in this age range who received the Unplugged program had similar drug consumption levels to those observed before the program began. However, students in the control group presented a significant tendency to increase marijuana use and binge drinking. This study adds to the evidence of program efficacy among Brazilian middle school students by presenting marginal effects on binge drinking and marijuana use. An 18-month randomized controlled trial is recommended for a future study.

An overview will be presented of music therapy, art therapy, movement therapy and reminiscence therapy, memory training, reality orientation, validation therapy, self-maintenance therapy, behaviour therapy, milieu therapy and staff training. The overview will examine the aims of each, the principles on which procedures are based and the proof of their effectiveness. The principal aim of non-drug therapies is to influence symptomatic dementia beneficially and to improve the abilities remaining to the patient. The potential benefits are usually deduced from studies made without control groups. At the present time, proof of the effectiveness of these therapies is still lacking as controlled, randomized studies have yet to be conducted, and so a fundamental evaluation of the therapeutic benefits of non-drug therapies in the treatment of dementia cannot yet be made.

Full Text Available It is generally accepted that development of novel therapies to treat pregnancy-relates disorders, such as preeclampsia, is hampered to the paucity of research funding. Hence, it is with great interest to become aware of at least three novel therapeutic approaches for the treatment of this disorder, exploiting either the anticoagulant activity of antithrombin, the free radical scavenging activity of alpha-1-microglobulin, or the regenerative capacity of placenta-derived mesenchymal stem cells. As these projects are being carried out by small biotech enterprises, the question arises of how they are able to fund such undertakings. A novel strategy adopted by two of these companies is that they successfully petitioned US and EU agencies in order that preeclampsia be accepted in the register of rare or orphan diseases. This provides a number of benefits including market exclusivity, assistance with clinical trials and dedicated funding schemes. Other strategies to supplement meager research funds, especially to test novel approaches, could be crowdfunding, a venture which relies on intimate interaction with advocacy groups. In other words, preeclampsia meets Facebook. Perhaps similar strategies can be adopted to examine novel therapies targeting either the imbalance in angiogenic growth factors, complement activation, reduced levels of placenta protein 13 or excessive neutrophil activation evident in preeclampsia.

Antibacterial chemotherapy against Helicobacter pylori is currently being assessed by open or randomized controlled clinical studies for its efficacy in eradicating this bacterium from the stomach of patients with gastritis or gastroduodenal ulcer. Whereas there is presently no "optimal" agent and treatment scheme, the combination of some antibiotics (metronidazole, tinidazole, amoxicillin) with bismuth salts proves definitely superior in vivo to either of these agents administered alone. Several reasons have been proposed, to explain the clinical failure after treatment: insufficient concentration of active drugs in gastric mucus, instability of some agents at an acidic pH, inappropriate formulation of drug, insufficient duration of treatment, and variable compliance of patients. Recently, it has appeared from several clinical trials that H. pylori may rapidly acquire resistance to some antibiotics, and that this event might also account for clinical failure. A critical review of the literature on H. pylori treatment indicates that association of bismuth and antibiotics or of antibiotics alone both may efficiently reduce the risk of emergence of resistance and improve the therapeutic outcome. Guidelines of treatment are suggested in order to avoid the future misuse of antibiotics that would increase selection of antibiotic-resistant H. pylori and negatively affect the ecology of the gastric microflora. Likewise, an accurate definition of a subset of patients with H. pylori who really will require treatment needs to be rapidly established.

This study aimed to demonstrate that curcumin (Cur)-containing graphene composites have high anticancer activity. Specifically, graphene-derivatives were used as nanovectors for the delivery of the hydrophobic anticancer drug Cur based on pH dependence. Different Cur-graphene composites were prepared based on polar interactions between Cur and the number of oxygen-containing functional groups of respective starting materials. The degree of drug-loading was found to be increased by increasing the number of oxygen-containing functional groups in graphene-derivatives. We demonstrated a synergistic effect of Cur-graphene composites on cancer cell death (HCT 116) both in vitro and in vivo. As-prepared graphene quantum dot (GQD)-Cur composites contained the highest amount of Cur nano-particles and exhibited the best anticancer activity compared to the other composites including Cur alone at the same dose. This is the first example of synergistic chemotherapy using GQD-Cur composites simultaneous with superficial bioprobes for tumor imaging. PMID:25204358
Full Text Available Abstract Introduction: This case study investigated the impact of preventive physical therapy on shoulder problems and the prevention of pressure ulcers (PU in a bedridden, home care, post-neurological surgery patient. Objective: To highlight the importance of physical therapy in the prevention of comorbidities, chronic neurological sequelae, and PU. Materials and Methods: In the immediate post-surgical phase, the patient was treated with preventive measures against PU, according to the Pressure Ulcer Prevention Protocol of the University of São Paulo, the National Pressure Ulcer Advisory Panel, and the Braden Scale. In addition, we used the modified Ashworth scale to assess spasticity. A kinesiotherapy program based on the Bobath's concept was used to prevent subluxation of the plegic arm and help in the recovery of functional movements. Results: The use of preventive measures and delivery of humanized care during a six-month period helped prevent the development of stage 3 and 4 PU and physical, functional, and respiratory complications. By the end of six months, the patient was found to be at low risk of developing PU. Conclusion: Notwithstanding the difficulties experienced during treatment, especially for the positioning of the arm and performance of transferring and positioning techniques, the results of this study are in agreement with aspects considered important for treatment outcomes.

Background: Isoniazid preventive therapy (IPT) is a recommended strategy for prevention of tuberculosis (TB) in persons with Human Immunodeficiency Virus (HIV) although the benefits have not been unequivocally demonstrated in routine clinical practice with widespread ART adoption. Therefore, we
Full Text Available Diabetic vascular complications are the most common cause of mortality and morbidity worldwide, with numbers of affected individuals steadily increasing. Diabetic vascular complications can be divided into two categories: macrovascular and microvascular complications. Macrovascular complications include coronary artery disease and cerebrovascular disease, while microvascular complications include retinopathy and chronic kidney disease. These complications result from metabolic abnormalities, including hyperglycemia, elevated levels of free fatty acids, and insulin resistance. Multiple mechanisms have been proposed to mediate the adverse effects of these metabolic disorders on vascular tissues, including stimulation of protein kinase C signaling and activation of the polyol pathway by oxidative stress and inflammation. Additionally, the loss of tissue-specific insulin signaling induced by hyperglycemia and toxic metabolites can induce cellular dysfunction and both macro- and microvascular complications characteristic of diabetes. Despite these insights, few therapeutic methods are available for the management of diabetic complications. Recently, incretin-based therapeutic agents, such as glucagon-like peptide-1 and dipeptidyl peptidase-4 inhibitors, have been reported to elicit vasotropic actions, suggesting a potential for effecting an actual reduction in diabetic vascular complications. The present review will summarize the relationship between multiple adverse biological mechanisms in diabetes and putative incretin-based therapeutic interventions intended to prevent diabetic vascular complications.
