    Objective: Relapse is a major problem in drug addiction treatment. Both drug craving and drug-related cognitions (e.g., attentional bias and implicit attitudes to drugs) may contribute to relapse. Using ecological momentary assessments, we examined whether craving and cognitions assessed during drug detoxification treatment were associated with…

    Men and women entering drug treatment programs are known to differ in demographic characteristics and psychosocial behavioral patterns. To be effective, any such program that caters to individuals from both sexes should identify and address these gender-based variations. Studies have also reported clinical differences in the effect of drugs on men and women addicts. Here, we examine whether the treatment is equally effective on men and women, when several demographic covariates are controlled. We construct a "problem severity index" to categorize individuals based on how acute their problems were at the start of the program. We also examine how the choice of treatment modality affects treatment success. Cumulative logit models were used in our analysis. The choice of treatment modality is sex specific, although sex did not appear to be a significant factor for treatment effectiveness when we controlled for other explanatory variables.

    Full Text Available Research on assessing craving in laboratory settings often involves inducing and then measuring craving in subjects. Cue-induced craving is studied in laboratory settings using the cue reactivity paradigm, in which drug-related photos, videos, evocative scripts, olfactory cues, and paraphernalia may induce craving. Cue-induced craving evoked by drug-related stimuli could be associated with relapse and recurrence of drug addiction. In this article, the authors review different methods of assessing craving in laboratory settings and explain how human laboratory settings can bridge the gap between randomized clinical trials (RCTs and animal models on pharmacological treatments for drug dependence. The brief reviewed literature provides strong evidence that laboratory-based studies of craving may improve our understanding of how subjective reports of drug craving are related to objective measures of drug abuse and laboratory settings provide an opportunity to measure the degree to which they co-vary during pharmacological interventions. This issue has important implications inclinical studies.

    Full Text Available  ABSTRACTDescribing drug treatment given by general practitioners, and quantifying changes in their prescribingbehaviour due to educational intervention, were important parts of the method developed and appliedby the European Drug Education Project. Based on the physicians’ prescription data, individual patientswere defined as having either asthma or urinary tract infections. Prescribing indicators were establishedfor assessing the quality (acceptable or unacceptable of the drug treatment. The diagnose definitionsand prescribing indicators are discussed in more detail in relation to feeding back individual prescribingdata to educational groups of physicians to improve the quality of their drug therapy.

    France is one of the European countries that spend the most on oncology drugs. To keep pharmaceutical expenditure under control, Health Authorities highly scrutinize market access of costly medicines. To assess current and future trends in French health technology assessment (HTA) of antineoplastic drugs indicated in the treatment of solid tumours. A review of the SMR and ASMR drivers of the Transparency Committee (CT) opinions issued for antineoplastic drugs indicated in the treatment of solid tumours and approved between 2009 and 2014 was performed to assess current trends in French health technology assessment (HTA), complemented by an expert board consultation to capture the critical issues on the future of antineoplastic drugs HTA. Thirty-one drugs indicated for the treatment of solid tumours were identified (77 % targeted therapies). Initial CT assessments were available for 26 drugs. Four key items in the CT assessment were identified: 1) Clinical trial methodology; 2) Acceptance of progression-free survival (PFS) as a valuable endpoint; 3) Transferability of clinical trials in clinical practice; 4) Unpredictability of CT decisions. Experts raised the important development of personalised medicines in oncology and key challenges for oncology products to generate information expected from HTA perspective. The French system remains committed to its values and philosophy (access of all innovations for everybody) which are threatened by the increasing launch of innovative therapies and budget constraint. Both HTA decision framework evolution and revision of the current pricing process should be considered in France to cope with these new challenges.

  7. Research on a 'drug-centred' approach to psychiatric drug treatment: assessing the impact of mental and behavioural alterations produced by psychiatric drugs.

    Moncrieff, J

    2017-10-12

    This article explores an alternative understanding of how psychiatric drugs work that is referred to as the drug-centred model of drug action. Unlike the current disease-centred model, which suggests that psychiatric drugs work by correcting an underlying brain abnormality, the drug-centred model emphasises how psychiatric drugs affect mental states and behaviour by modifying normal brain processes. The alterations produced may impact on the emotional and behavioural problems that constitute the symptoms of mental disorders. Arguments are put forward that justify the consideration of the drug-centred model. The research necessary to support the prescription of drugs according to such a model is explored. Evidence from neurochemistry and comparative drug trials do not confirm the disease-centred model of drug action. Since psychiatric drugs are recognised to have mind- and behaviour-altering properties, the drug-centred model constitutes a plausible alternative. The drug-centred model suggests that research is needed to identify all the alterations produced by various sorts of drugs, both acute and long term, and how these might interact with the symptoms and problems associated with different mental disorders. This requires detailed animal and volunteer studies and data from patients prescribed drug treatment long term, along with placebo-controlled and comparative trials that look at the overall impact of drug-induced alterations on well-being and functioning as well as symptoms. Research is also needed on alternative ways of fulfilling the function of drug treatment. The moral aspect of using drugs to modify behaviour rather than treat disease needs honest and transparent consideration. It is hoped this discussion will encourage the psychiatric and pharmaceutical research community to provide more of the information that is required to use psychiatric drugs safely and effectively.

    Drug testing is an important clinical tool that is available to physicians who are assessing the effectiveness of drug treatment as well as patient compliance to the administered program. While urine has traditionally been the matrix of choice for drug monitoring, oral fluid, a filtrate of the blood, has shown great promise as an alternative matrix for such applications. Oral fluid collection can be accomplished without the need for highly trained medical staff through the use of a simple, noninvasive oral fluid collection device, which obtains an adequate sample in only a few minutes. There has been a significant amount of research performed on the use of oral fluid for forensic toxicology application; however, more studies assessing the use of oral fluid drug testing are required to validate its ability to achieve clinical drug monitoring goals. Testing for various drugs in oral fluid may yield a different result when compared to the same drugs in urine, requiring an assessment of the utility of oral fluid for such practices. The purpose of this study was to examine the application of oral fluid drug testing in patients undergoing buprenorphine treatment for opioid dependence. A retrospective analysis of drug testing results obtained from 6,928 patients (4,560 unobserved urine collections and 2,368 observed oral fluid collections) monitored for heroin metabolite, amphetamine, benzodiazepines, buprenorphine, tetrahydrocannabinol, cocaine, codeine, hydrocodone, hydromorphone, methadone, morphine, oxycodone, and oxymorphone was completed. Results of this statistical exercise indicated that patients undergoing observed oral fluid collection tested positive more frequently than those unobserved urine collections for several illicit drugs and prescription medications targeted. Oral fluid was shown to detect illicit drug use as well as noncompliance in this patient population under the studied conditions more often than the urine specimens.

    Anticholinergic drugs reduce the efficacy of acetylcholinesterase inhibitors (AChEI) and are inappropriate in elderly patients. The aim of this study is to determine the prevalence rate of prescription AChEI drugs and anticholinergics in a Healthcare Area, to identify the affected patients, and to inform the attending physicians, in order to evaluate the suitability of treatments. A descriptive cross-sectional observational study of prevalence. Patients on treatment with AChEI and any anticholinergic drug in the first quarter of 2015 were selected. The review of Duran et al. was used as reference to identify anticholinergics, assigning a score to each drug according to its anticholinergic potency. Physicians were provided with a report about the interaction, the list of affected patients, and recommendations. A total of 486 patients were included in the study, representing 59.0% of total patients with Alzheimer's disease in the Area. There were 66.0% women, and 86.8% of the patients were older than 75 years, and with a mean of 9.2 drugs per patient. The mean number of anticholinergic drugs was 1.6, and 38.3% of patients were prescribed various anticholinergic drugs, with 23.9% on high potency anticholinergic drugs. A statistically significant association was found between taking an anticholinergic and AChEI concomitantly (P=.000; OR: 3.9). The prevalence of interactions between AChEI and anticholinergic drugs is relevant, considering that it affects vulnerable members of the population. Providing physicians with information about the interaction could help them make clinical decisions, and could improve patient safety, as well as health outcomes. Copyright © 2015 SEGG.

    This paper reports preliminary data derived from a standardized interview scoring procedure for detecting and characterizing coercive and noncoercive pressures to enter substance abuse treatment. Coercive and noncoercive pressures stemming from multiple psychosocial domains are operationalized through recourse to established behavioral principles. Inter-rater reliability for the scoring procedure was exceptional over numerous rater trials. Substantive analyses indicate that, among clients in outpatient cocaine treatment, 'coercion' is operative in multiple psychosocial domains, and that subjects perceive legal pressures as exerting substantially less influence over their decisions to enter treatment than informal psychosocial pressures. Implications for drug treatment planning, legal and ethical issues, and directions for future research are proposed.

    Professionals who provide drug treatment to young people regularly encounter what they conceive to be inauthentic client claims, that is, claims not in accordance with reality. Earlier research demonstrates how authenticity remains a key concern within drug treatment, but it has not sufficiently...... of ulterior motives, clients are interpreted as making inauthentic claims because they want to obtain something externally from drug treatment (e.g., avoid prison or work training programs), and (3) the story of disorders explains inauthenticity as a result of pathology.

    Among people who inject drugs (PWID) with chronic HCV, the association between HCV treatment willingness and intent, and HCV specialist assessment and treatment were evaluated. The Enhancing Treatment for Hepatitis C in Opioid Substitution Settings (ETHOS) is a prospective observational cohort. Recruitment was through six opioid substitution treatment clinics, two community health centres and one Aboriginal community controlled health organisation in Australia. Analyses were performed using logistic regression. Among 415 participants (mean age 41 years, 71% male), 67% were 'definitely willing' to receive HCV treatment and 70% reported plans to initiate therapy 12 months postenrolment. Those definitely willing to receive HCV treatment were more likely to undergo specialist assessment (64% vs 32%, P < 0.001) and initiate therapy (36% vs 9%, P < 0.001), compared to those with lower treatment willingness. Those with early HCV treatment plans were more likely to undergo specialist assessment (65% vs 27%, P < 0.001) and initiate therapy (36% vs 5%, P < 0.001), compared to those without early plans. In adjusted analyses, HCV treatment willingness independently predicted specialist assessment (aOR 3.06, 95% CI 1.90, 4.94) and treatment uptake (aOR 4.33, 95% CI 2.14, 8.76). In adjusted analysis, having early HCV treatment plans independently predicted specialist assessment (aOR 4.38, 95% CI 2.63, 7.29) and treatment uptake (aOR 9.79, 95% CI 3.70, 25.93). HCV treatment willingness was high and predicted specialist assessment and treatment. Strategies for enhanced HCV care should be developed with an initial focus on people willing to receive treatment and to increase treatment willingness among those less willing. © 2015 John Wiley & Sons Ltd.

    Access to hepatitis C virus (HCV) treatment remains extremely limited among people who inject drugs (PWID). HCV assessment and treatment was evaluated through an innovative model for the provision of HCV care among PWID with chronic HCV infection. Enhancing Treatment for Hepatitis C in Opioid Substitution Settings (ETHOS) was a prospective observational cohort. Recruitment was through 5 opioid substitution treatment (OST) clinics, 2 community health centers, and 1 Aboriginal community controlled health organization in New South Wales, Australia. Among 387 enrolled participants, mean age was 41 years, 71% were male, and 15% were of Aboriginal ethnicity. Specialist assessment was undertaken in 191 (49%) participants, and 84 (22%) commenced interferon-based treatment. In adjusted analysis, HCV specialist assessment was associated with non-Aboriginal ethnicity (adjusted odds ratio [AOR], 4.02; 95% confidence interval [CI], 2.05-7.90), no recent benzodiazepine use (AOR, 2.06; 95% CI, 1.31-3.24), and non-1 HCV genotype (AOR, 2.13; 95% CI, 1.32-3.43). In adjusted analysis, HCV treatment was associated with non-Aboriginal ethnicity (AOR, 4.59; 95% CI, 1.49-14.12), living with the support of family and/or friends (AOR, 2.15; 95% CI, 1.25-3.71), never receiving OST (AOR, 4.40; 95% CI, 2.27-8.54), no recent methamphetamine use (AOR, 2.26; 95% CI, 1.12-4.57), and non-1 HCV genotype (AOR, 3.07; 95% CI, 1.67-5.64). HCV treatment uptake was relatively high among this highly marginalized population of PWID. Potentially modifiable factors associated with treatment include drug use and social support.

    Although the basic paradigm of the U.S. federal drug policy targeting the supply and demand reduction has not changed since its enactment in 1970, there have been seriously undesirable disparate treatments and impacts among various population groups. Although U.S. Congress could not define what is discrimination, it did provide two major criteria for the assessment of discriminatory practices as follows: (a) disparate treatment-basing a key decision on association with any of the five prohibited individual's demographic classifications (race, color, religion, sex, or national origin); and (b) disparate impact-correlation between any of the five prohibited demographic classifications and the key outcomes. In reference to those criteria, this article describes evidence-based indicators of national failure of the Comprehensive Drug Abuse Prevention and Control Act.

    The Food and Drug Administration issued guidance for evaluating the cardiovascular risk of new diabetes mellitus drugs in 2008. Accumulating evidence from several completed trials conducted within this framework raises questions as to whether requiring safety outcome studies for all new diabetes mellitus therapies remains justified. Given the burden of cardiovascular disease in patients with diabetes, the focus should shift towards cardiovascular outcome studies designed to evaluate efficacy (i.e. to determine the efficacy of a drug over placebo or standard care) rather than demonstrating that risk is not increased by a pre-specified safety margin. All stakeholders are responsible for ensuring that new drug approvals occur under conditions of appropriate safety and effectiveness. It is also a shared responsibility to avoid unnecessary hurdles that may compromise access to useful drugs and threaten the sustainability of health systems. It is critical to renew this debate so that stakeholders can collectively determine the optimal approach for developing new drugs to treat type 2 diabetes mellitus. PMID:27418973

    Our aim was to determine the efficiency of the Medication Compliance Self-Report Inventory (MASRI) in self-reporting antimuscarinic drug treatment compliance among women with urinary incontinence (UI). The study assessed 347 women aged 18-65 (averaging 49.7) years with more than one urinary incontinence (UI) episode per day. Treatment compliance was tested at the beginning and at weeks 4, 8, and 12 using the MASRI, the Brief Medication Questionnaire (BMQ), and visual pill counts. The MASRI's constructive, concurrent, and discriminate validity was studied in comparison with an external standard that uses the chi-square and Spearman coefficient. Receiver operating characteristic (ROC) analysis was performed to identify optimum MASRI cutoffs that would predict noncompliance. Furthermore, the functional condition of the lower urinary tract was tested using voiding diaries, uroflowmetry, and cystometry. The correlation between the percentage of noncompliant women according to the MASRI, and individuals with a belief barrier with respect to the BMQ screen was r = 0.81 (p ≤0.05), r = 0.84 (p ≤0.05), and r = 0.79 (p ≤0.05). The correlation between the percentage of noncompliant women according to the MASRI and of women who missed >20% of their doses according to the Regimen Screen of the BMQ was r = 0.79, p ≤0.05, r = 0.82, p ≤0.01, r = 0.77, and p ≤0.05 at the control points. Finally, the percentage of noncompliant patients who self-reported correctly according to the MASRI data compared with the BMQ was 95.6%, 95.7%, and 96.6% at the control points. The MASRI entails acceptable validity for accurately predicting treatment compliance with antimuscarinic drugs among women who have had UI for >3 months.

    Full Text Available Ignacio Garcia-Valladares, Raquel Cuchacovich, Luis R EspinozaSection of Rheumatology, Department of Internal Medicine, LSU Health Sciences Center, New Orleans, LA, USAAbstract: The development of psoriasis and psoriatic arthritis is a multistep process that leads to chronic or recurrent inflammation. Recent studies have suggested the importance of T helper (TH1 and TH17 cells, accessory cells, and proinflammatory cytokines in the pathogenesis of the enthesis, synovium, and skin involvement in psoriasis in the presence of susceptibility genes that remain quiescent until triggered. Biologics, such as soluble CTLA-4 immunoglobulin, tumor necrosis factor (TNF inhibitors, and ustekinumab, inhibit T cell activation which eventually leads to further stimulation of the interleukin 12, 17, and 23 axis, TNF-α, and lymphotoxin-α. Treatment with TNF-α blockers has been effective in refractory psoriasis and psoriatic arthritis, but there is still a subgroup of patients who do not respond to TNF inhibitors and, paradoxically, when treated, may develop TNF-induced psoriasis. Ustekinumab, because of its different mechanism of action at the level of the interleukin 12, 17, and 23 pathways, is an alternative treatment for this group of patients.Keywords: psoriasis, psoriatic arthritis, biologics, ustekinumab, tumor necrosis factor inhibitors

    In Malaysia, compulsory drug detention centres (CDDCs) hold suspected drug users for two years without adjudication. Acute detoxification without healthcare access has been documented. CDDCs are criticized globally due to ineffectiveness in treating addiction and human rights violations. In response, the Malaysian government began transitioning these facilities into voluntary drug treatment centres known as "Cure and Care" (C&C) centres that embrace a holistic treatment-based approach to drug addiction rehabilitation. An explorative qualitative study was undertaken to explore patient perspectives and satisfaction regarding treatment and services at the new Cure and Care centre in Kota Bharu, Malaysia. A convenience sample of 20 patients was recruited to participate in semi-structured in-depth interviews. Content analysis was used to identify the salient themes. Patients identified methadone treatment, psychosocial programs, religious instruction, and recreational activities as important factors contributing to treatment success for addressing both health and addiction needs. Though many had previously been in a CDDC, adherence to treatment in the C&C centre was perceived to be facilitated by the degree of social support, the voluntary nature and the array of new programs available for selection. C&Cs represents a dramatic shift in the Malaysian government's approach to drug addiction. Our findings demonstrate positive patient experiences associated with the holistic treatment-based approach of these centres. This exploratory study provides additional evidence to document this ongoing policy transition and may guide continued expansion of new holistic drug treatment programs across the country.

    2015-10-01

    Alopecia is the term used to describe hairless areas of the scalp. They can follow a specific pattern, be diffuse or circumscript. Androgenetic alopecia (AGA) follows a pattern: in men thinning of temples and vertex up to total baldness; in women thinning of the midline or parietal area. Lack of iron or cytostatic drugs cause diffuse alopecia, while in autoimmune diseases such as alopecia areata or lichen planus bizarre shapes of hairless areas are observed. For therapy, the following medications are used: topical minoxidil solution for AGA of men and women; systemic finasteride 1 mg for men with AGA; topical diphencyprone immunotherapy for alopecia areata; systemic antimycotic agents for tinea capitis; antibiotics such as clindamycin and rifampicin for folliculitis decalvans; systemic corticosteroids and isotretinoin for folliculitis et perifolliculitis capitis abscedens et suffodiens; topical corticosteroids for lichen planus and Kossard's frontal fibrosing alopecia.

    The objective was to assess social functioning and its association with treatment intent, specialist assessment and treatment uptake for hepatitis C virus (HCV) infection among people with a history of injecting drug use. ETHOS is a prospective observational cohort evaluating the provision of HCV assessment and treatment among people with chronic HCV and a history of injecting drug use, recruited from nine community health centres and opioid substitution treatment clinics (NSW, Australia). Social functioning was assessed using a short form of the Opioid Treatment Index social functioning scale. Those classified in the highest quartile (score >6) were considered having lower social functioning. Analyses were performed using logistic regression. Among 415 participants (mean age 41 years, 71% male), 24% were considered having lower social functioning, 70% had early HCV treatment intent (intention to be treated in the next 12 months), 53% were assessed by a specialist and 27% initiated treatment. Lower social functioning was independently associated with unemployment, unstable housing, recent injecting drug use and moderate to extremely severe symptoms of depression, anxiety and stress. Lower social functioning was independently associated with reduced early HCV treatment intent (aOR 0.51, 95% CI 0.30-0.84) and lower specialist assessment (aOR 0.48, 95% CI 0.29-0.79), but not HCV treatment uptake (aOR 0.76, 95% CI 0.40-1.43). Living with someone was independently associated with HCV treatment uptake (with someone and children: aOR 2.28, 95% CI 1.01-5.14; with someone and no children: aOR 2.36, 95% CI 1.30-4.31), but not early HCV treatment intent or specialist assessment. This study highlights the need for the development and implementation of strategies targeting people who inject drugs with lower social functioning to enhance HCV treatment intent and specialist assessment. Further, strategies to enhance social support may play a role in increasing HCV treatment

    Most economic evaluations in the literature on the subject of biologic therapy for the treatment of psoriasis do not reflect normal clinical practice or consider the cost of patient management. The objective of the present study is to establish a model for assessing the efficiency of biologic therapies in the treatment of psoriasis taking into account the cost of managing treatment which, in routine clinical practice, depends on patient response. We developed a model based on a decision tree that incorporates the probability of treatment response or failure with adalimumab, etanercept, infliximab, and ustekinumab after 24 weeks of therapy (end of the induction phase). The probability in each case was calculated using data from a meta-analysis. The following direct health costs were taken into account: the cost of drugs and their administration in euro (2015). Our analysis was based on the cost of 12 months of treatment administered in a hospital setting. According to the proposed model, the mean cost per year by initial treatment strategy was lowest for patients who started treatment with ustekinumab, although the percentage cost difference between ustekinumab and infliximab or adalimumab was less than 3%. With a fixed budget of €1,000,000, the initial treatment option that would achieve success in the largest number of patients for one year would, according to this model, be ustekinumab (66 patients), followed by infliximab (n = 62), adalimumab (n = 59), and etanercept (n = 50). Sensitivity analysis confirmed the reliability of these results. However, considering the confidence intervals of the incremental efficacy observed in the meta-analysis, the differences found are probably not significant in all the possible binary comparisons. Likewise, possible differences in actual price structures, populations, and the strategies and therapeutic objectives of each hospital could all give rise to considerable variations in real life. The cost of managing treatment in

    To investigate the heterogeneous factors affecting the stability of patients older than 60 years in the UI treatment with Antimuscarinics. The prevalence of Urge Incontinence (UI) in older persons reaches 29.3%. The symptoms of urinary incontinence in older people reduce the health related life quality. In 1257 patients over 60 years (857 (68.2%) women - average age 67.8, 400 (31.8%) men - 71.4), who received AM for one year, demographic, socio-economic and health parameters were studied. OABq-SF questionnaires, MOS SF-36, urination diaries, uroflowmetry, income information from the tax offices and outpatient records were used. The compliance to AM treatment within 6 months was retained in 44.2%, and within the year - 26.8% of older patients. At least 40% of the total number of patients refused to continue the treatment for medical reasons. The persons taking Solifenacin (p≤ 0.01), Trospium (p≤ 0.05), or Darifenacin (p≤ 0.05), suffering from severe UI symptoms (p≤ 0.01), and experiencing minor side effects (p≤ 0.01), well-informed about UI treatment methods (p≤ 0.01) prevailed among the treatment compliant patients. At least 20.4% of the patients discontinued their treatment due to economic reasons. The persons with significantly larger annual income (p≤ 0.05) and annual medical cost (p≤ 0.01) prevailed among the treatment compliant patients. About 12.2% of the patients stopped their treatment for reasons related to the social background and psychological status. In this experiment, we found that AM treatment compliance in older patients, in addition to medical parameters and health conditions, is largely affected by the economic as well as social, demographic and psychological factors. The study results can be claimed by practitioners involved in correcting UI symptoms in older people. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.

    2015-01-08

    Tuberculosis is an airborne infectious disease treated with combination therapeutic regimens. Adherence to long-term antituberculosis therapy is crucial for maintaining adequate blood drug level. The emergence and spread of drug-resistant Mycobacterium tuberculosis strains are mainly favored by the inadequate medical management of the patients. The therapeutic approach for drug-resistant tuberculosis is cumbersome, because of the poor, expensive, less-effective, and toxic alternatives to the first-line drugs. New antituberculosis drugs (bedaquiline and delamanid) have been recently approved by the health authorities, but they cannot represent the definitive solution to the clinical management of drug-resistant tuberculosis forms, particularly in intermediate economy settings where the prevalence of drug resistance is high (China, India, and former Soviet Union countries). New research and development activities are urgently needed. Public health policies are required to preserve the new and old therapeutic options.

    To illustrate the current situation and problems of drug addiction in treatment China and propose suggestions. A descriptive study based on literature searched from Medline and the China National Knowledge Infrastructure database (1996-2007) and hand-picked references. Since the re-emergence of drug addiction in China in the early 1990s, there has been tremendous progress in drug addiction treatments in China, especially treatments for opiate addiction. However, many problems and challenges remain for improvement, including widespread negative attitudes towards drug abuse and drug-dependent individuals, the lack of evidence-based data on the efficacy of Chinese traditional medicine and the lack of a comprehensive and integrated system to organize all treatment resources and monitor treatment progress. The authors discuss the challenges that impede effective treatments of drug addiction and some suggestions are proposed. Implementing these suggestions can improve the outcome of treatment of drug-dependent individuals and benefit the whole society. China faces substantial drug addiction problems that appear to be worsening with time. Although much progress in drug addiction treatment has been made, improvement in many aspects is needed urgently.

    This pilot study compared the pharmacologic treatment history and clinical outcomes observed in pediatric outpatients with psychiatric disorders exposed to drugs of abuse in utero to those of an age-matched, sex-matched and psychiatric disorder-matched, non-drug-exposed group. In this matched cohort study, medical records of children treated at an academic, child and adolescent psychiatry outpatient clinic were reviewed. Children with caregiver-reported history of prenatal drug exposure were compared with a non-drug-exposed control group being cared for by the same providers. Patients were rated with the Clinical Global Impressions-Severity scale (CGI-S) throughout treatment. The changes in pre-treatment and post-treatment CGI-S scores and the total number of medication trials were determined between groups. The drug-exposed group (n = 30) had a higher total number of lifetime medication trials compared with the non-drug-exposed group (n = 28) and were taking significantly more total medications, at their final assessment. Unlike the non-drug-exposed group, the drug-exposed group demonstrated a lack of clinical improvement. These results suggest that in utero drug-exposed children may be more treatment-refractory to or experience greater side effects from the pharmacologic treatment of psychiatric disorders than controls, although we cannot determine if early environment or drugs exposure drives these findings.

    In the first phase of a two-part treatment development study, families with a treatment-resistant, drug-abusing adolescent (n=42) were offered 12 sessions of Community Reinforcement and Family Training (CRAFT). This parent-focused intervention was designed to help parents facilitate their adolescents' entry in treatment and support adolescents' subsequent behavior change and to improve parent and family functioning. In the second phase, successfully engaged adolescents (n=30) were offered 12 sessions of a multicomponent individual cognitive behavioral therapy (CBT) targeting substance use and related problem behaviors. Measures were collected at pre- and post-treatment for parents and adolescents, with an additional follow-up assessment for parents at 3-months post-treatment. Parents in the CRAFT intervention experienced a significant reduction in negative symptoms and 71% of parents were successful in engaging their resistant youth in treatment. The CBT intervention for the engaged youth was associated with a statistically significant, but not clinically significant, reduction in marijuana use. PMID:17306722

This cross-sectional study describes the characteristics of female drug offenders that use stimulants and clarifies the factors related to the awareness of treatment for drug dependencies. We included 80 females imprisoned due to stimulant control law violations from 2012 to 2015. The characteristics of the female prisoners were stratified according to various treatment awareness levels, and associations between each characteristic and treatment awareness were evaluated using logistic regression models. The average period of stimulant drug use was 17.7 years. Participants imprisoned for the second time were significantly more likely to consider treatment compared to those imprisoned only once: odds ratio (OR = 3.2 (95% confidence interval (CI: 1.0–10.7. This elevated OR was diluted in repeat offenders. Participants who had experienced multiple aftereffects (≥7 or serious depressive symptoms were also more likely to consider treatment: OR = 6.1 (95% CI: 1.8–20.8 and OR = 2.5 (95% CI: 1.0–6.2, respectively. Second-time stimulant offenders or offenders who had experienced health problems were more likely to consider it important to receive drug dependence treatment. To overcome relapses of stimulant use, it is recommended that stimulant use offenders are encouraged to accept adequate treatment.

Many markets produce nonproprietary medicines; assessing their efficacy and safety is difficult as regulators may approve nonproprietary drugs without bioequivalence data, genotoxic evaluation, or risk management plans (RMPs. This assessment is especially important for fingolimod given its solubility/bioavailability profile, genotoxicity risk, and low-dose final product (0.5 mg. This paper presents an evaluation of the quality of proprietary and nonproprietary fingolimod variants.Methods: Proprietary fingolimod was used as a reference substance against which eleven nonproprietary fingolimod copies were assessed. The microparticle size distribution of each compound was assessed by laser light diffraction, and inorganic impurity content by sulfated ash testing. Heavy metals content was quantified using inductively coupled plasma optical emission spectrometry, and levels of unspecified impurities by high-performance liquid chromatography. Solubility was assessed in a range of solvents at different pH values. Key information from the fingolimod RMP is also presented.Results: Nonproprietary fingolimod variants exhibited properties out of proprietary or internationally accepted specifications, including differences in particle size distribution and levels of impurities such as heavy metals.

  5. Drug treatment of functional dyspepsia.

    2006-05-07

    Symptomatic improvement of patients with functional dyspepsia after drug therapy is often incomplete and obtained in not more than 60% of patients. This is likely because functional dyspepsia is a heterogeneous disease. Although great advance has been achieved with the consensus definitions of the Rome I and II criteria, there are still some aspects about the definition of functional dyspepsia that require clarification. The Rome criteria explicitly recognise that epigastric pain or discomfort must be the predominant complaint in patients labelled as suffering from functional dyspepsia. However, this strict definition can create problems in the daily primary care clinical practice, where the patient with functional dyspepsia presents with multiple symptoms. Before starting drug therapy it is recommended to provide the patient with an explanation of the disease process and reassurance. A thorough physical examination and judicious use of laboratory data and endoscopy are also indicated. In general, the approach to treat patients with functional dyspepsia based on their main symptom is practical and effective. Generally, patients should be treated with acid suppressive therapy using proton-pump inhibitors if the predominant symptoms are epigastric pain or gastroesophageal reflux symptoms. Although the role of Helicobacter pylori (H pylori) in functional dyspepsia continues to be a matter of debate, recent data indicate that there is modest but clear benefit of eradication of H pylori in patients with functional dyspepsia. In addition, H pylori is a gastric carcinogen and if found it should be eliminated. Although there are no specific diets for patients with FD, it may be helpful to guide the patients on healthy exercise and eating habits.

    The Ministry of Public Health (MOPH) in Lebanon provides cancer drugs free of charge for uninsured patients who account for more than half the total caseload. Other categories of cancer care are subsidized under more stringent eligibility criteria. MOPH's large database offers an excellent opportunity to analyze the cost of cancer treatment in Lebanon. Using utilization and spending data accumulated at MOPH during 20082013, the cost to the public budget of cancer drugs was assessed per case and per drug type. The average annual cost of cancer drugs was 6,475$ per patient. Total cancer drug costs were highest for breast cancer, followed by chronic myeloid leukemia (CML), colorectal cancer, lung cancer, and NonHodgkin's lymphoma (NHL), which together represented 74% of total MOPH cancer drug expenditure. The annual average cancer drug cost per case was highest for CML ($31,037), followed by NHL ($11,566). Trastuzumab represented 26% and Imatinib 15% of total MOPH cancer drug expenditure over six years. Sustained increase in cancer drug cost threatens the sustainability of MOPH coverage, so crucial for socially vulnerable citizens. To enhance the bargaining position with pharmaceutical firms for drug cost containment in a small market like Lebanon, drug price comparisons with neighboring countries which have already obtained lower prices may succeed in lowering drug costs.

    Janković Slobodan

    2015-01-01

    Full Text Available Headache frequently occurs after spinal anesthesia or after craniotomy, especially after removal of acoustic neuroma. Headache after spinal anesthesia is caused by leakage of liquor through dural puncture and decrease of intracranial pressure, while pain after craniotomy is consequence of operative injury of peri-cranial muscles and soft tissues. Epidural administration of morphine and intravenous administration of cosyntropine or aminophylline at the end of a surgical intervention may prevent postoperative headache, while caffeine, gabapentin, pregabalin, theophylline, hydrocortisone or cosyntropine are efficient in the treatment. Drugs are not efficient for prevention of headache after craniotomy, while parenteral codeine and/or acetaminophen can terminate this type of pain. Non-steroid antiinflammatory drugs should be avoided for treatment of post-craniotomy headache, due to their extraand intra-cranial adverse effects. Timely administration of appropriate drugs for prevention or treatment of postoperative headache significantly decreases suffering, hastens recovery and prevent chronic headache.

    The increasing prevalence of obesity represents a huge threat to public health and the current pharmacological treatment options are limited. Bariatric surgery is by far the most effective treatment for severe obesity, highlighting the urgent need for new and improved drug therapies. Areas covered: Based on the physiological regulation of energy homeostasis, pharmacological strategies to treat obesity are evaluated with focus on drugs in phase 2 and 3 clinical development. The potential impact of these drugs on current treatment standards and the barriers for development are discussed and set in a historical perspective of previous antiobesity medications. Expert opinion: The radical effects of bariatric surgery have extended our understanding of the mechanisms controlling appetite and boosted the search for new drug targets in obesity treatment. Accordingly, several compounds targeting the central nervous system and/or periphery are in pipeline for obesity. These drugs should be evaluated over a wide array of end-points; in particular, long-term safety monitoring is necessary as serious adverse events may appear. Combination therapy targeting more than one pathway controlling energy balance might be necessary to achieve substantial weight loss while minimising side effects.

    2017-10-16

    Drug-Drug Interactions (DDI) by modulation of drug transporters or drug metabolizing enzymes are common in multi-drug therapy. DDI potential of any new drug is assessed by conducting separate clinical studies using relevant probe substrates, which involves additional resource and cost. Recently, several endogenous compounds have been evaluated as substrates of transporters and enzymes that could be assessed as part of early clinical trials along with the assessment of drug pharmacokinetics, pharmacodynamics and safety studies. This enables an early readout on potential DDIs avoiding or minimally delaying the conduct of definitive DDI studies until later in clinical development. This review describes various endogenous biomarkers reported for drug transporters and metabolizing enzymes with their advantages and limitations. Furthermore, the authors describe strategies to adopt while exploring a new endogenous biomarker, and factors to be considered in selection of biomarkers with the current challenges and opportunities.

Children aged 6-7 years were screened for Wuchereria bancofti antigen using the immunochromatographic card (ICT) method. A cluster sampling method was used to select eligible children in schools as the net primary-school enrolment ratio is greater than or equal to 75% in each of the four EUs. The number of children and schools to be selected in each EU, the randomization list for the selection of these children and the critical cut-off number of positive cases not to exceed were automatically generated using the Survey Sample Builder (SSB) tool, (NTD Support Center, Atlanta, Ga, USA). For confirmation, positive cases were subsequently tested for microfilaremia using nocturnal thick blood smear and for filarial antigen using Og4C3 antigen ELISA (TropBio ELISA Kit®, Townsville, Queensland, Australia). An EU is considered to have passed the test successfully (it is assumed that transmission can no longer be sustained), when the number of positive cases is below the critical cut-off number set by the SSB, which is roughly equivalent to 2% prevalence. Of the 1 706 children surveyed in Kpendjal-Tone's EU, 1 549 in Binah-Doufelgou's EU, 1 550 in Kozah's EU and the 1 575 in Amou-Haho's EU, 8 (0.46%), 1 (0.08%), 0 (0.00%) and 4 (0.25%) ICT positive cases respectively were detected. The number of positive ICT tests was well below 18, the critical cut number for each of the 4 EUs. All 13 ICT positive cases tested negative for nocturnal microfilaremia and Og4C3 ELISA. We conclude that all four EU passed the TAS with success, and the transmission of Wuchereria bancrofti is no longer likely to be sustained in the 7 endemic districts in Togo

    The prevalence of injection drug use (IDU) and incidence of human immunodeficiency virus (HIV) remain high in Baltimore, where IDU is a primary HIV risk factor. Substance use disorders and HIV are related syndemically--their causes and consequences interact synergistically. Baltimore is increasingly considering the syndemic relationship of substance use disorders, IDU, and HIV in making decisions about drug treatment funding and location. Our goal was to empirically identify the optimal location of new drug treatment programs through the development and application of a novel, practical tool. Syndemic triangles were constructed to measure and visualize unmet need for drug treatment services. These data were used to determine priority zones for new treatment centers. The application of this tool helped inform strategies for locating drug treatment services in Baltimore, and its successful use suggests its potential value in other metropolitan areas.

    Thus, the present research was carried out aimed at determining the relationship between self-esteem and locus of control and quality of life during treatment stages in the patients referring to drug addiction rehabilitation centers of Borujen city, Iran. The current study was a sectional research of descriptive correlation type. The research sample was 150 individuals of patients referring to addiction rehabilitation centers of Borujen city. For data gathering, Rosenberg Self-esteem Scale, Rotter's Locus of Control Scale, and SF36 Quality of Life Questionnaire were used. Following collection of questionnaires, the data were analyzed using SPSS/16 software. According to the results, in the 12(th) day of treatment, 96 patients exhibited moderate self-esteem, 102 patients had internal locus of control, and the score of their overall quality of life was 40.43±12.71. Furthermore, Pearson's correlation coefficient indicated that a significant and positive relationship was observed between locus of control and quality of life during different treatment stages. It seems that quality of life improves during addiction treatment stages due to improvement of personality traits including locus of control and self-esteem. Therefore, consultation methods as a very crucial priority in addiction rehabilitation centers shall be taken into account by the health sector authorities and managers and can play an essential role in enhancing quality of life.

  18. Designer drugs 2015: assessment and management.

    Science.gov (United States)

    Weaver, Michael F; Hopper, John A; Gunderson, Erik W

    2015-03-25

    Recent designer drugs, also known as "legal highs," include substituted cathinones (e.g., mephedrone, methylone, and methylenedioxypyrovalerone, often referred to as "bath salts"); synthetic cannabinoids (SCs; e.g., Spice); and synthetic hallucinogens (25I-NBOMe, or N-bomb). Compound availability has evolved rapidly to evade legal regulation and detection by routine drug testing. Young adults are the primary users, but trends are changing rapidly; use has become popular among members of the military. Acute toxicity is common and often manifests with a constellation of psychiatric and medical effects, which may be severe (e.g., anxiety, agitation, psychosis, and tachycardia), and multiple deaths have been reported with each of these types of designer drugs. Clinicians should keep designer drugs in mind when evaluating substance use in young adults or in anyone presenting with acute neuropsychiatric complaints. Treatment of acute intoxication involves supportive care targeting manifesting signs and symptoms. Long-term treatment of designer drug use disorder can be challenging and is complicated by a lack of evidence to guide treatment.

    2007-01-06

    Antiobesity treatment is recommended for selected patients in whom lifestyle modification is unsuccessful. Two antiobesity drugs are currently licensed for long-term use. Orlistat, a gastrointestinal lipase inhibitor, reduces weight by around 3 kg on average and decreases progression to diabetes in high-risk patients; adverse gastrointestinal effects are common. Sibutramine, a monoamine-reuptake inhibitor, results in mean weight losses of 4-5 kg, but is associated with increases in blood pressure and pulse rate. Rimonabant, the first of the endocannabinoid receptor antagonists, reduces weight by 4-5 kg on average and improves waist circumference and concentrations of HDL cholesterol and triglyceride; however, an increased incidence of mood-related disorders has been reported. To date, all antiobesity drug trials have been limited by their high attrition rates and lack of long-term morbidity and mortality data. Other promising antiobesity drugs, including those acting within the central melanocortin pathway, are in development, but are years away from clinical use. In light of the lack of successful weight-loss treatments and the public-health implications of the obesity pandemic, the development of safe and effective drugs should be a priority. However, as new drugs are developed we suggest that the assessment processes should include both surrogate endpoints (ie, weight loss) and clinical outcomes (ie, major obesity-related morbidity and mortality). Only then can patients and their physicians be confident that the putative benefits of such drugs outweigh their risks and costs.

    We assessed prevalence of suicidal ideation and plans among illicit drug users and their association with contextual factors, by gender. Cross-sectional study. In a sample of 511 illicit drug users recruited during spring 2012 in drug treatment and prevention facilities in Catalonia (Spain), the prevalence of suicidal ideation/plans in the last 12 months was assessed. Poisson regression was used to examine associations between suicidal ideation/plans and various factors (socio-demographic, psychological, illegal drug market activities and marginal income generation activities, which included any reported sex work, stealing, peddling, begging or borrowing on credit from a dealer). The average age was 37.9 years (standard deviation: 8.62); 76.3% were men. Suicidal ideation/plans were reported by 30.8% of men and 38.8% of women, with no significant differences by age or gender. Recent aggression (male prevalence ratio [PR]=2.2; female PR=1.4), psychological treatment (male PR=1.2; female PR=1.3) and illegal/marginal income generation activities (male PR=1.5; female PR=1.1) were associated with suicidal ideation/plans. Men who trafficked were more likely to have suicidal ideation/plans (PR=1.3), while prison history was positive for women (PR=1.8) and negative for men (PR=0.7). Prevalence of suicidal ideation/plans was high among illicit drug users recruited from healthcare facilities. Besides psychological variables, participation in illegal market activities and crime ought to be considered in drug users' suicidal prevention. Suicide risk needs to be evaluated in drug treatment facilities and psychological status and context contemplated. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

    The purpose of this study was to assess the compliance with tuberculostatic drugs treatment in a public hospital from Córdoba City and to establish the causes of noncompliance. All the patients to which treatment with tuberculostatic drugs was indicated from January 1991 up to December 1994 were included. 45 patients were included: 18 females (40%) and 29 males. Sixteen (35.6%) did not complete the time of treatment indicated. Nine (56.3%) abandoned the treatment 2 months after having initiated it. In the group that did not complete the treatment there was a higher percentage of female patients (62.5%) than in the group that did complete it (27.6%), p = 0.02. There were not statistically significant differences in age, percentages of pulmonar and extrapulmonar tuberculosis and months of treatment indicated between both groups. Thirty-six percent of the patients who abandoned the treatment referred having interrupted it due to their own negligency, knowing the risk of such behavior; 36% suffered side effects and did not come back to hospital; 21% referred having consulted another physician who indicated to interrupt the treatment without performing other tests; and 7% misunderstood the indications. It is concluded that in a general hospital from Córdoba City, the percentage of patients who abandoned tuberculostatic treatment is high. In most cases the cause was related to failures in the conduct of patients, physicians or both.

    Regional health bodies in British Columbia (BC) issue drug alerts to the public when health risks associated with drug quality are identified, such as increased illicit drug deaths, overdoses or other harms. There is a lack of evidence-based guidelines for producing timely, effective public health alerts to mitigate these harms. This study sought to understand (1) the practices used by people who use drugs (PWUD) to assess the quality of street drugs and reduce harms from adulterants and (2) how drug alerts could be better communicated to PWUD. Guided by interpretive and descriptive methodology, this study consisted of brief questionnaires and in-depth focus groups with 32 PWUD. Findings suggest the most effective and trusted information about drug quality was primarily from: (a) trusted, reputable dealers or (b) peer-based social networks. Most PWUD thought information received through health service providers was not timely and did not discuss drug quality with them. A number of concrete guidelines were suggested by participants to improve the effectiveness of drug alert modes and methods of communication in the community, including the use of language on drug alert postings that implies harm, indicates what drug effects to look for, and suggests appropriate responses to overdose, such as the use of naloxone. Participants also emphasized the need to date posters and remove them in a timely manner so as to not desensitize the community to such alerts. Since it is difficult to control adulteration practices in an unregulated drug market, this study suggests methods of effectively producing and communicating drug alerts among PWUD to mitigate harms associated with drug use.

    Full Text Available Cryptosporidiosis emergence triggered the screening of many compounds for potential anti-cryptosporidial activity in which the majority were ineffective. The outbreak of cryptosporidiosis which occurred in Milwaukee in 1993 was not only the first significant emergence of Cryptosporidium spp. as a major human pathogen but also a huge waterborne outbreak thickening thousands of people from a major city in North America. Since then, outbreaks of cryptosporidiosis are regularly occurring throughout the world. New drugs against this parasite became consequently urgently needed. Among the most commonly used treatments against cryptosporidiosis are paromomycin, and azithromycin, which are partially effective. Nitazoxanide (NTZ’s effectiveness was demonstrated in vitro, and in vivo using several animal models and finally in clinical trials. It significantly shortened the duration of diarrhea and decreased mortality in adults and in malnourished children. NTZ is not effective without an appropriate immune response. In AIDS patients, combination therapy restoring immunity along with antimicrobial treatment of Cryptosporidium infection is necessary. Recent investigations focused on the potential of molecular-based immunotherapy against this parasite. Others tested the effects of probiotic bacteria, but were unable to demonstrate eradication of C. parvum. New synthetic isoflavone derivatives demonstrated excellent activity against C. parvum in vitro and in a gerbil model of infection. Newly synthesized nitroor non nitro- thiazolide compounds, derived from NTZ, have been recently shown to be at least as effective as NTZ against C. parvum in vitro development and are promising new therapeutic agents.

    Torsades de pointes (TdP) is a potentially lethal cardiac arrhythmia that can occur as an unwanted adverse effect of various pharmacological therapies. Before a drug is approved for marketing, its effects on cardiac repolarisation are examined clinically and experimentally. This paper expresses...... the opinion that effects on repolarisation duration cannot directly be translated to risk of proarrhythmia. Current safety assessments of drugs only involve repolarisation assays, however the proarrhythmic profile can only be determined in the predisposed model. The availability of these proarrhythmic animal...... surrogate parameters possessing predictive power of TdP arrhythmia are reviewed. As these parameters are not developed to finalisation, any meaningful study of the proarrhythmic potential of a new drug will include evaluation in an integrated model of TdP arrhythmia....

    2016-01-01

    Introduction Anxiety disorders are among the most prevalent and disabling psychiatric disorders in the United States and worldwide. Basic research has provided critical insights into the mechanism regulating fear behavior in animals and a host of animal models have been developed in order to screen compounds for anxiolytic properties. Despite this progress, no mechanistically novel agents for the treatment of anxiety have come to market in more than two decades. Areas covered The current review will provide a critical summary of current pharmacological approaches to the treatment of anxiety and will examine the pharmacotherapeutic pipeline for treatments in development. Anxiety and related disorders considered herein include panic disorder, social anxiety disorder, generalized anxiety disorder and posttraumatic stress disorder. The glutamate, neuropeptide and endocannabinoid systems show particular promise as future targets for novel drug development. Expert opinion In the face of an ever-growing understanding of fear related behavior, the field awaits the translation of this research into mechanistically novel treatments. Obstacles will be overcome through close collaboration between basic and clinical researchers with the goal of aligning valid endophenotypes of human anxiety disorders with improved animal models. Novel approaches are needed to move basic discoveries into new, more effective treatments for our patients. PMID:26012843

    Full Text Available Background. The aim of the study was to explore the epidemiology of drug abuse treatment in South Africa. Methods. Treatment demand statistics were analysed from South African National Council on Alcoholism and Drug Dependence and the South African Community Epidemiology Network on Drug Use records, and a rapid situation assessment was conducted. Twenty-one key informant interviews were conducted in all 9 provinces among provincial substance abuse co-ordinators, and one manager per treatment centre from a sample of treatment centres. Three focus groups were conducted and 46 self-administered questionnaires were distributed among inpatients at 2 selected treatment centres in Free State and North West provinces. Qualitative data were analysed using grounded theory, and quantitative data analysed using SPSS. Results. Treatment records show that the most frequent substance of abuse was alcohol (51%, followed by cannabis (21%, crack/cocaine (9.6%, heroin/opiates (7.9%, methamphetamine (Tik (4.5%, prescription/over-the-counter drugs (2.0%, and cannabis/mandrax (1.7%. More substance abusers were male, of lower education, white or black, than were female, more highly educated, coloured and Indian/Asian. Key informant interviews showed that females are the ‘hidden’ substance abusers and tend not to be identified in research statistics and at treatment centres. Poverty, unemployment, lack of recreational facilities, being surrounded by substance abusers, and long work shifts were also mentioned as factors contributing to substance abuse. The age of initiation of substance abuse using non-drugs such as glue was 9 years old, alcohol 10 - 12 years old, dagga 11 - 12 years old, poly-drug use (alcohol, tobacco and dagga 14 years old, and harder drugs such as cocaine and heroin at 16 - 17 years old, as reported by key informants. Family care and support, improved socio-economic conditions and increased law enforcement would help to discourage substance

    We developed a homogeneous bridging anti-drug antibody (ADA) assay on an electro chemiluminescent immunoassay (ECLIA) platform to support the immunogenicity evaluation of a dimeric domain antibody (dAb) therapeutic in clinical studies. During method development we evaluated the impact of different types of acid at various pH levels on polyclonal and monoclonal ADA controls of differing affinities and on/off rates. The data shows for the first time that acids of different pH can have a differential effect on ADA of various affinities and this in turn impacts assay sensitivity and drug tolerance as defined by these surrogate controls. Acid treatment led to a reduction in signal of intermediate and low affinity ADA, but not high affinity or polyclonal ADA. We also found that acid pretreatment is a requisite for dissociation of drug bound high affinity ADA, but not for low affinity ADA-drug complexes. Although we were unable to identify an acid that would allow a 100% retrieval of ADA signal post-treatment, use of glycine pH3.0 enabled the detection of low, intermediate and high affinity antibodies (Abs) to various extents. Following optimization, the ADA assay method was validated for clinical sample analysis. Consistencies within various parameters of the clinical data such as dose dependent increases in ADA rates and titers were observed, indicating a reliable ADA method. Pre- and post-treatment ADA negative or positive clinical samples without detectable drug were reanalyzed in the absence of acid treatment or presence of added exogenous drug respectively to further assess the effectiveness of the final acid treatment procedure. The overall ADA results indicate that assay conditions developed and validated based on surrogate controls sufficed to provide a reliable clinical data set. The effect of low pH acid treatment on possible pre-existing ADA or soluble multimeric target in normal human serum was also evaluated, and preliminary data indicate that acid type and

    1985-09-16

    This paper sets out the arguments for drug treatment of chronic glomerulonephritides (GN). Although the pathogenesis and mechanism of progression of chronic GN remained to be clarified, on the basis of controlled studies performed to date, there is a strong case to be made for an aggressive treatment approach to this disease spectrum. For instance, in patients with idiopathic membranous glomerulonephritis a six months treatment with chlorambucil (0.2 mg/KG/day) or prednisone (0.6 mg/KG/day) each given once a day over a period of three months has recently been shown to improve the outcome of the renal functional parameters after three years follow up. In another controlled trial a daily dose of 225 mg dipyridamole and 975 mg aspirin given over 12 months in patients with membrano-proliferative GN type I has been reported to normalize the increased platelet consumption rate and to stabilize the glomerular filtration rate. A third trial has demonstrated that the combined use of cyclophosphamide (100 mg/day) and prednisone (30 mg/day) over several months was superior to the use of prednisone alone (40 mg/day) in improving the long-term prognosis of diffuse-proliferative lupus nephritis (type IV, WHO). In some entities, however, as in IgA-nephritis there is still no evidence for a specific treatment improving the course of the chronic glomerular disease. Other therapeutic problems have to be solved: thus, in patients with minimal change nephropathy with a steroid dependent nephrotic syndrome the benefit of cyclophosphamide (given over three months) or of cyclosporin A is still being investigated. Furthermore, there is some evidence that progression of chronic GN, particularly that of glomerular sclerosing, can be prevented by a low protein diet. The role of eicosanoides and their inhibitors in this context has not yet been fully investigated. The different drug trials and new therapeutic concepts indicate a rapid development of chronic GN treatment. Therefore, a failure

    Many women will likely experience a sexual problem in their lifetime. Female sexual dysfunction is a broad term used to describe 3 categories of disorders of a multifactorial nature. Effective, but limited pharmacotherapeutic options exist to address female sexual dysfunction. The FDA recently approved the first agent for treatment of hypoactive sexual desire disorder in pre-menopausal women. Off-label use of hormonal therapies, particularly oestrogen and testosterone, are the most widely employed for female sexual dysfunction, particularly in post-menopausal women. Other drugs currently under investigation include phosphodiesterase inhibitors and agents that modulate dopamine or melanocortin receptors.

    In a number of developing countries there is reportedly a high incidence of the availability of substandard drugs. The majority of these reports do not contain quantitative data to support these claims, nor do they describe the methodology employed for the quality assessment. Many assume counterfeiting as the reason for the poor quality and in some cases this is not justified. We collected 96 samples of chloroquine and selected antibacterials from Nigeria and Thailand in a controlled and methodical manner and analysed them using appropriately validated methods based on high-performance liquid chromatography capable of detecting drug-related impurities and quantifying active drug(s). The results indicate that 36.5% of the samples were substandard with respect to pharmacopoeial limits. Decomposition was the cause of poor quality in a number of the samples but overall, poor manufacturing appeared to be prevalent. The analyses generated little evidence to indicate fraudulent manufacturing. Treatment failure and drug-resistance are possible consequences of the use of substandard drugs.

    Full Text Available In the 1960s, discovery of pleasure system (defined as reward system in the brain that may underlie drug reward and addiction encouraged many scientists to investigate the mechanisms by which drug abuse affects central nervous system function. In this regard, investigators developed several drugs targeting the brain reward system for drug dependence therapy. However, no positive results obtained in drug addiction treatment. It seems that more brain systems other than brain reward system must be considered in this regard.

    Dan Carter carefully layered the sheets of tracing paper on the light box. On each sheet were renderings of the atomic components of an essential human protein, one whose structure had long been a mystery. With each layer Carter laid down, a never-before-seen image became clearer. Carter joined NASA s Marshall Space Flight Center in 1985 and began exploring processes of protein crystal growth in space. By bouncing intense X-rays off the crystals, researchers can determine the electron densities around the thousands of atoms forming the protein molecules, unveiling their atomic structures. Cultivating crystals of sufficient quality on Earth was problematic; the microgravity conditions of space were far more accommodating. At the time, only a few hundred protein structures had been mapped, and the methods were time consuming and tedious. Carter hoped his work would help reveal the structure of human serum albumin, a major protein in the human circulatory system responsible for ferrying numerous small molecules in the blood. More was at stake than scientific curiosity. Albumin has a high affinity for most of the world s pharmaceuticals, Carter explains, and its interaction with drugs can change their safety and efficacy. When a medication enters the bloodstream a cancer chemotherapy drug, for example a majority of it can bind with albumin, leaving only a small percentage active for treatment. How a drug interacts with albumin can influence considerations like the necessary effective dosage, playing a significant role in the design and application of therapeutic measures. In spite of numerous difficulties, including having no access to microgravity following the 1986 Space Shuttle Challenger disaster, the image Carter had hoped to see was finally clarifying. In 1988, his lab had acquired specialized X-ray and detection equipment a tipping point. Carter and his colleagues began to piece together albumin s portrait, the formation of its electron densities coalescing on

  3. Drug treatment strategies for epilepsy revisited: starting early or late? One drug or several drugs?

    Science.gov (United States)

    Schmidt, Dieter

    2016-12-01

    There are two popular strategies for current drug treatment of epilepsy; starting early may be better and polytherapy conveys advantages over monotherapy. This review briefly examines if the historical record is much of a guide to determine the clinical value of these two strategies. Great clinical scientists of the 19th and early 20th century, such as Sir William Gowers, and William Aldren Turner, offered vivid single case studies and showed early results of seizure remission in groups of subjects. The historical record offered, however, no evidence of clear clinical benefits for early treatment and polytherapy. Combination treatment was thought to be useful in only some cases. In agreement, current evidence shows no clear clinical benefit of starting treatment early, except perhaps in severe epilepsy. Polytherapy is clinically useful in a subgroup of subjects, but despite being a standard treatment strategy for over one hundred years, it has been poorly studied. In fact, there is no compelling experimental or clinical evidence for a difference in seizure outcome between monotherapy and polytherapy. This surprising finding should prompt a re-appraisal regarding the need to test both strategies separately for the licensing of new antiepileptic drugs.

  6. Recommendations for Optimizing Tuberculosis Treatment: Therapeutic Drug Monitoring, Pharmacogenetics, and Nutritional Status Considerations.

    2017-03-01

    Although tuberculosis is largely a curable disease, it remains a major cause of morbidity and mortality worldwide. Although the standard 6-month treatment regimen is highly effective for drug-susceptible tuberculosis, the use of multiple drugs over long periods of time can cause frequent adverse drug reactions. In addition, some patients with drug-susceptible tuberculosis do not respond adequately to treatment and develop treatment failure and drug resistance. Response to tuberculosis treatment could be affected by multiple factors associated with the host-pathogen interaction including genetic factors and the nutritional status of the host. These factors should be considered for effective tuberculosis control. Therefore, therapeutic drug monitoring (TDM), which is individualized drug dosing guided by serum drug concentrations during treatment, and pharmacogenetics-based personalized dosing guidelines of anti-tuberculosis drugs could reduce the incidence of adverse drug reactions and increase the likelihood of successful treatment outcomes. Moreover, assessment and management of comorbid conditions including nutritional status could improve anti-tuberculosis treatment response.

    2010-12-01

    Drug use continues to be a major factor fueling the global epidemic of HIV infection. This article reviews the current literature on the ability of drug treatment programs to reduce HIV transmission among injection and noninjection drug users. Most data come from research on the treatment of opiate dependence and provide strong evidence on the effectiveness of medication-assisted treatment for reducing the frequency of drug use, risk behaviors, and HIV infections. This has been a consistent finding since the epidemic began among diverse populations and cultural settings. Use of medications other than methadone (such as buprenorphine/naloxone and naltrexone) has increased in recent years with promising data on their effectiveness as HIV prevention and as new treatment options for communities heavily affected by opiate use and HIV infection. However, few treatment interventions for stimulant abuse and dependence have shown efficacy in reducing HIV risk. The cumulative literature provides strong support of drug treatment programs for improving access and adherence to antiretroviral treatment. Drug users in substance abuse treatment are significantly more likely to achieve sustained viral suppression, making viral transmission less likely. Although there are challenges to implementing drug treatment programs for maximum impact, the scientific literature leaves no doubt about the effectiveness of drug treatment as an HIV prevention strategy.

  11. Assessing multiparametric drug response in tissue engineered tumor microenvironment models.

    2017-12-16

    The tumor microenvironment is important in promoting treatment resistance of tumor cells via multiple mechanisms. However, studying this interaction often proves difficult. In vivo animal models are costly, time-consuming, and often fail to adequately predict human response to treatment. Conversely, testing drug response on human tumor cells in vitro in 2D cell culture excludes the important contribution of stromal cells and biophysical forces seen in the in vivo tumor microenvironment. Here, we present tissue-engineered models of both human brain and breast tumor microenvironments incorporating key stromal cell populations for assessing multiple mechanisms of therapeutic response using flow cytometry. We show our physiologically-relevant systems used to interrogate a variety of parameters associated with chemotherapeutic efficacy, including cell death, proliferation, drug uptake, and invasion of cancer and stromal cell populations. The use of flow cytometry allows for single cell, quantitative, and fast assessments of multiple outcomes affecting anti-tumor therapy failure. Our system can be modified to add and remove cellular components with ease, thereby enabling the study of individual cellular contributions in the tumor microenvironment. Together, our models and analysis methods illustrate the importance of developing fast, cost-effective, and reproducible methods to model complex human systems in a physiologically-relevant manner that may prove useful for drug screening efforts in the future.

    Although evidence exists for distinct barriers to drug abuse treatment (BDATs), investigations of their inter-relationships and the effect of individual characteristics on the barrier factors have been sparse, especially in China. A Multiple Indicators Multiple Causes (MIMIC) model is applied for this target. A sample of 262 drug users were recruited from three drug rehabilitation centers in Hunan Province, China. We applied a MIMIC approach to investigate the effect of gender, age, marital status, education, primary substance use, duration of primary drug use, and drug treatment experience on the internal barrier factors: absence of problem (AP), negative social support (NSS), fear of treatment (FT), and privacy concerns (PC). Drug users of various characteristics were found to report different internal barrier factors. Younger participants were more likely to report NSS (-0.19, p=0.038) and PC (-0.31, pdrug users, ice users were more likely to report AP (0.44, pDrug treatment experiences related to AP (0.20, p=0.012). In addition, differential item functioning (DIF) occurred in three items when participant from groups with different duration of drug use, ice use, or marital status. Individual characteristics had significant effects on internal barriers to drug treatment. On this basis, BDAT perceived by different individuals could be assessed before tactics were utilized to successfully remove perceived barriers to drug treatment.

    Full Text Available Background and the purpose of the study: Tuberculosis is curable if patients take sufficient uninterrupted therapy. Most experts acknowledge importance of patient adherence in efforts to control of the disease. This cross-sectional study was designed to evaluate the rate of compliance to anti-tuberculosis regimens by means of urine tests in newly diagnosed tuberculosis patients.Method: Investigation was carried out in Tehran University of Medical Sciences Teaching Hospitals, Tehran, IRAN. Fifty patients completed the study. The patients' urine samples were obtained at 0, 1, 2, 4 and 6 months of the study. Simple chemical methods were used to detect Isoniazid, Rifampin, and pyrazinamide, the three main drugs in tuberculosis treatment regimens. Urine tests at months of 0 and l of the study were considered as control tests.Results: After the first month, the patients' compliance was about 96%. At months of second, fourth and sixth, the whole adherence rates were 56 %, 76% and 81% respectively. Conclusion: About 30% of patients were non-compliant with treatment regimen which was more frequent than presumed; therefore detection of non-adherent patients is an essential subject in developing countries.

    2013-01-01

    A web-based survey was used to consult the opinions of experienced drug users on matters related to drug harms. We identified a rare sample of 93 drug users with personal experience with 11 different illicit drugs that are widely used in the UK. Asked to assess the relative harms of these drugs, they ranked alcohol and tobacco as the most harmful, and three "Class A" drugs (MDMA, LSD, and psilocybin) and one class B (cannabis) were ranked as the four least harmful drugs. When asked to assess the relative potential for benefit of the 11 drugs, MDMA, LSD, psilocybin, and cannabis were ranked in the top four; and when asked why these drugs are beneficial, rather than simply report hedonic properties, they referred to potential therapeutic applications (e.g., as tools to assist psychotherapy). These results provide a useful insight into the opinions of experienced drug users on a subject about which they have a rare and intimate knowledge.

    2013-06-01

    Adolescence is an exciting and challenging period of maturation, rapid brain development, and developmental changes in neurobiological, neurocognitive, and neurobehavioral processes. Although behavioral therapies available for adolescent substance abuse have increased, effectiveness research in this area lags considerably behind that of clinical research on treatment for drug-abusing adults. Behavioral treatment approaches show significant promise for treating drug-abusing adolescents, but many have not incorporated innovations in neuroscience on brain development, cognitive processes, and neuroimaging. Linking developmental neuroscience with behavioral treatments can create novel drug abuse interventions and increase the effectiveness of existing interventions for substance-abusing adolescents. Contemporary research on brain development, cognition, and neuroscience is ripe for translation to inform developmentally sensitive drug abuse treatments for adolescents. Neuroscientists and interventionists are challenged to build mutual collaborations for integration of neuroscience and drug abuse treatment for adolescents. 2013 APA, all rights reserved

    BACKGROUND Extensively drug-resistant tuberculosis has been reported in 45 countries, including countries with limited resources and a high burden of tuberculosis. We describe the management of extensively drug-resistant tuberculosis and treatment outcomes among patients who were referred for individualized outpatient therapy in Peru. METHODS A total of 810 patients were referred for free individualized therapy, including drug treatment, resective surgery, adverse-event management, and nutritional and psychosocial support. We tested isolates from 651 patients for extensively drug-resistant tuberculosis and developed regimens that included five or more drugs to which the infecting isolate was not resistant. RESULTS Of the 651 patients tested, 48 (7.4%) had extensively drug-resistant tuberculosis; the remaining 603 patients had multidrug-resistant tuberculosis. The patients with extensively drug-resistant tuberculosis had undergone more treatment than the other patients (mean [±SD] number of regimens, 4.2±1.9 vs. 3.2±1.6; P<0.001) and had isolates that were resistant to more drugs (number of drugs, 8.4±1.1 vs. 5.3±1.5; P<0.001). None of the patients with extensively drug-resistant tuberculosis were coinfected with the human immunodeficiency virus (HIV). Patients with extensively drug-resistant tuberculosis received daily, supervised therapy with an average of 5.3±1.3 drugs, including cycloserine, an injectable drug, and a fluoroquinolone. Twenty-nine of these patients (60.4%) completed treatment or were cured, as compared with 400 patients (66.3%) with multidrug-resistant tuberculosis (P=0.36). CONCLUSIONS Extensively drug-resistant tuberculosis can be cured in HIV-negative patients through outpatient treatment, even in those who have received multiple prior courses of therapy for tuberculosis.

    Full Text Available The increase in the prescription of opioid analgesics is related to increased rates of opioid abuse and the negative consequences of medication misuse. Several international health organisations recommend comprehensive and multidisciplinary patient assessment for the duration of the opioid treatment in order to identify and prevent medication abuse. Due to the lack of specific clinical guidelines in the Spanish National Health System, the aim of this paper is to present a proposal for psychological assessment based on the main psychological tools currently available for assessing opioid abuse. The assessment guidelines have been established based on the psychological variables that can predict and prolong the abuse, classifying all of the variables depending on the current stage of the therapeutic process for each patient. Although there are instruments with good psychometric properties, further research is necessary to adapt, translate and validate these instruments for use in the Spanish population. Future studies are also needed to investigate intervention and prevention strategies in depth in order to reduce the likelihood of abuse in patients treated with opioids.

In all the studies presented here, relevant changes in weight of -5% to -10% are only partially achieved. High weight losses of less than -10% were found among the intervention group in two of the studies. One study reported a weight loss of -11.4% with the "group therapy" intervention method, while another study reported a weight loss of -11.2% with the "behaviour therapy plus drug treatment" intervention method. Studies with a subsequent follow-up period indicate a clear weight loss at the end of the intervention followed by a renewed weight gain towards the end of the follow-up period. For the evaluation of economic, social-ethical or legal aspects we could not identify any studies. A comparative assessment among the studies proved difficult due to their heterogeneous nature. Little conformity can be detected in either the contents of the behaviour therapy or in the treatment plans. The length of the follow-up periods also varies from study to study. Many studies only analyze weight changes within one group or for the entire study population. However, the results of these analyses all indicate a significant weight loss at the end of the intervention. Some effects of behaviour therapy on a reduction in weight can be shown. However, relevant weight changes of -5% to -10% are only achieved to a certain extent. The extremely heterogeneous nature of the interventions makes a comparison of the study results very difficult.

    Iyengar, Anjali; Davis, Jonathan M.

    2015-01-01

    Introduction: As more infants are surviving at younger gestational ages, bronchopulmonary dysplasia (BPD) remains as a frequent neonatal complication occurring after preterm birth. The multifactorial nature of the disease process makes BPD a challenging condition to treat. While multiple pharmacologic therapies have been investigated over the past two decades, there have been limited advances in the field. Often multiple therapies are used concurrently without clear evidence of efficacy, with potential for significant side effects from drug-drug interactions. Methods: Systematic literature review. Conclusion: Although there is physiologic rationale for the use of many of these therapies, none of them has single-handedly altered the incidence, severity, or progression of BPD. Future research should focus on developing clinically significant end-points (short and long term respiratory assessments), investigating biomarkers that accurately predict risk and progression of disease, and creating appropriate stratification models of BPD severity. Applying a multi-modal approach to the study of new and existing drugs should be the most effective way of establishing the optimal prevention and treatment regimens for BPD. PMID:25762933

    Many drug abusers have repeated exposure to treatment, yet little is known about the reasons some individuals re-enter treatment following relapse to drug use. This paper examines the predictors of treatment re-entry among cocaine abusers who relapsed to cocaine use (N = 347) within 5 years following their index treatment episode. In-depth assessments were conducted at treatment intake in 1991-93 and at 1 and 5 years following treatment discharge. About 44% of the sample returned to treatment, at an average of 2.6 years following discharge. A logistic regression analysis demonstrated that individuals who were African American, were previously married, used cocaine at least weekly after treatment discharge, and had more service needs at the time of index treatment were more likely to re-enter treatment. The findings suggest that a longer-term perspective on treatment utilization is needed to more fully address chronic substance abuse and the problems typically associated with it.

    Phycocyanin isolated from marine organisms has the characteristics of high efficiency and low toxicity, and it can be used as a functional food. It has been reported that phycocyanin has anti-oxidative function, anti-inflammatory activity, anti-cancer function, immune enhancement function, liver and kidney protection pharmacological effects. Thus, phycocyanin has an important development and utilization as a potential drug, and phycocyanin has become a new hot spot in the field of drug research. So far, there are more and more studies have shown that phycocyanin has the anti-cancer effect, which can block the proliferation of cancer cells and kill cancer cells. Phycocyanin exerts anti-cancer activity by blocking tumor cell cell cycle, inducing tumor cell apoptosis and autophagy, thereby phycocyanin can serve as a promising anti-cancer agent. This review discusses the therapeutic use of phycocyanin and focuses on the latest advances of phycocyanin as a promising anti-cancer drug.

    The method of treatment and the results obtained from the treatment of 50 Canadian patients addicted to narcotic drugs who went to England are recorded. These patients were first stabilized on the minimal dose of narcotic drug which permitted them to work, and to acquire security and self-respect. Then, after psychiatric treatment dealing with the basic problem of their personality disorder, complete withdrawal treatment of the narcotic drug was undertaken.Nine of 10 patients aged between 20 and 30, of good social and cultural background, have been relieved of dependence on drugs for over two years.The other 40 patients came from a different background. Nearly all had been imprisoned for drug offences and they had come to England to obtain treatment and to avoid further prison sentences in Canada.The 31 patients whose prison sentences had been directly connected with drug offences are working steadily and leading an apparently normal life.The remaining nine patients had been convicted of criminal acts before becoming addicted to narcotic drugs and, with two exceptions, the results of their treatment compare unfavourably with the other patients, seven having been convicted and imprisoned in London.

The total annual cost (ie, treatment and lost productivity due to symptoms to the US economy of dry eye can be more than $55 billion. Thus, the development of new drug treatments for dry eye is important for both the dry eye patient and the ophthalmic industry. There are many drugs in development for the treatment of dry eye. This manuscript reviews the drugs listed on the ClinicalTrials.gov website (FDA list of clinical trials being investigated for the treatment of dry eye. A large number of these drugs are designed to target a specific cause of dry eye and some of these drugs will be approved for clinical use in the next 10 years. This will result in a significant increase in the clinician’s choice of treatment and potentially better control of the dry eye patient's condition.

Analysis of primary outcomes had indicated that RBT participants spent significantly longer time in treatment and recovery housing than UC participants. The present study examined the ability of 9 risk markers—age, race, estimated gestational age at treatment entry, lifetime substance abuse treatment episodes, history of prostitution charges, history of serious depression, current heroin injection status, current housing status, and current partner substance use—to predict changes in HIV risks. Sexual risk declined for participant subgroups with prostitution-charge histories and unstable housing. Drug-use risk declined for heroin injectors and nondepressed participants. A relationship was found between number of lifetime drug treatment episodes and sexual and drug-use risk. The role of risk markers in the response of drug-dependent pregnant women to drug treatment require attention.

  5. Assessing website pharmacy drug quality: safer than you think?

    Directory of Open Access Journals (Sweden)

    Roger Bate

    Full Text Available BACKGROUND: Internet-sourced drugs are often considered suspect. The World Health Organization reports that drugs from websites that conceal their physical address are counterfeit in over 50 percent of cases; the U.S. Food and Drug Administration (FDA works with the National Association of Boards of Pharmacy (NABP to regularly update a list of websites likely to sell drugs that are illegal or of questionable quality. METHODS AND FINDINGS: This study examines drug purchasing over the Internet, by comparing the sales of five popular drugs from a selection of websites stratified by NABP or other ratings. The drugs were assessed for price, conditions of purchase, and basic quality. Prices and conditions of purchase varied widely. Some websites advertised single pills while others only permitted the purchase of large quantities. Not all websites delivered the exact drugs ordered, some delivered no drugs at all; many websites shipped from multiple international locations, and from locations that were different from those advertised on the websites. All drug samples were tested against approved U.S. brand formulations using Raman spectrometry. Many (17 websites substituted drugs, often in different formulations from the brands requested. These drugs, some of which were probably generics or perhaps non-bioequivalent copy versions, could not be assessed accurately. Of those drugs that could be assessed, none failed from "approved", "legally compliant" or "not recommended" websites (0 out of 86, whereas 8.6% (3 out of 35 failed from "highly not recommended" and unidentifiable websites. CONCLUSIONS: Of those drugs that could be assessed, all except Viagra(R passed spectrometry testing. Of those that failed, few could be identified either by a country of manufacture listed on the packaging, or by the physical location of the website pharmacy. If confirmed by future studies on other drug samples, then U.S. consumers should be able to reduce their risk by

    Lucioni, C

    Two reasons provide historical justification for controlling drug prices: safeguarding the consumer and safeguarding public demand. Due to the increased presence of the "third payer" in public health systems this second reason has become more important. Nevertheless, over the last decade, a third purpose has attached to public control of prices: promotion of drug manufacturers economic development. The justification offered for this is that development of pharmaceutical companies contributes to the economic growth of the host country by creating employment, exports and research activity. The situations in Germany, Great Britain and United States are often cited in support of this thesis. As a model for price policy in Italy, however, it has not been successful. The rapid growth of prices in fact has not created greater employment and the foreign exchange deficit has risen rapidly. In other words the growing cost of drugs to the National Health Service has not produced hoped-for economic benefits. It would therefore be opportune to modify the mechanisms of price control by seeking a better balance in the interests involved (safeguarding public demand versus manufacturers economic growth). Methodologies available point to the evaluation of the therapeutic utility of a drug as a useful tool for this purpose. By this method the price of a new drug may only be higher than that of a drug already on the market if its therapeutic utility (which does not coincide only with clinical effectiveness) is greater. Appropriate evaluation techniques of benefits deriving from a new drug (cost-effectiveness and cost-utility) do exist and can be taken into consideration in a new method of calculating drug price.

    Full Text Available Systematic outcome assessment is central to ascertaining the impact of treatment services and to informing future treatment initiatives. This project was designed to be conducted within the clinical operations of 4 private addictions treatment centers. A structured interview was used to assess patients’ alcohol and other drug use and related variables (on treatment entry and at 1, 3, and 6 months following treatment discharge. The primary outcomes were percentage of days abstinent (PDA from alcohol and drugs, PDA from alcohol, and PDA from other drugs. Collateral reports during follow-up also were gathered. A total of 280 patients (56% men across the 4 programs participated. Percentage of days abstinent for each outcome increased significantly from baseline to the 1-month follow-up assessment, and this change was maintained at the 3- and 6-month follow-up assessments. Collateral reports mirrored the patient follow-up reports. Secondary outcomes of patient ratings of urges/cravings, depression, anxiety, and general life functioning all indicated significant improvement from baseline over the course of the follow-up. The results suggest the feasibility of conducting systematic outcome assessment in freestanding private addictions treatment environments.

    Full Text Available Introduction: Pre-treatment HIV drug resistance (PDR is an increasing problem in sub-Saharan Africa. Children are an especially vulnerable population to develop PDR given that paediatric second-line treatment options are limited. Although monitoring of PDR is important, data on the paediatric prevalence in sub-Saharan Africa and its consequences for treatment outcomes are scarce. We designed a prospective paediatric cohort study to document the prevalence of PDR and its effect on subsequent treatment failure in Nigeria, the country with the second highest number of HIV-infected children in the world. Methods: HIV-1-infected children ≤12 years, who had not been exposed to drugs for the prevention of mother-to-child transmission (PMTCT, were enrolled between 2012 and 2013, and followed up for 24 months in Lagos, Nigeria. Pre-antiretroviral treatment (ART population-based pol genotypic testing and six-monthly viral load (VL testing were performed. Logistic regression analysis was used to assess the effect of PDR (World Health Organization (WHO list for transmitted drug resistance on subsequent treatment failure (two consecutive VL measurements >1000 cps/ml or death. Results: Of the total 82 PMTCT-naïve children, 13 (15.9% had PDR. All 13 children harboured non-nucleoside reverse transcriptase inhibitor (NNRTI mutations, of whom seven also had nucleoside reverse transcriptase inhibitor resistance. After 24 months, 33% had experienced treatment failure. Treatment failure was associated with PDR and a higher log VL before treatment initiation (adjusted odds ratio (aOR 7.53 (95%CI 1.61–35.15 and 2.85 (95%CI 1.04–7.78, respectively. Discussion: PDR was present in one out of six Nigerian children. These high numbers corroborate with recent findings in other African countries. The presence of PDR was relevant as it was the strongest predictor of first-line treatment failure. Conclusions: Our findings stress the importance of implementing fully

    This article is exploring different forms of constraint that are exerted in the field of drug addiction treatment. The objective of this article is to establish benchmarks and to stimulate reflection about the ethical and clinical implications of those constraints in the field of drug addiction treatment. This article is presenting a critical review of different forms of constraint that can be exerted in Canada in regard to the treatment of drug addiction. In the first section of the article, a definition of therapeutic intervention is proposed, that includes the dimension of power, which justifies the importance of considering the coercive aspects of treatment. The second section, which represents the core section of the paper, is devoted to the presentation of different levels of constraint that can be distinguished in regard to drug addicts who are under treatment. Three levels of constraint are exposed: judicial constraint, institutional constraint and relational constraint. The coercive aspect of treatment can then be recognized as a combination of all tree levels of constraint. Judicial constraint refers to any form of constraint in which the court or the judge is imposing or recommending treatment. This particular level of constraint can take different forms, such as therapeutic remands, conditions of a probation order, conditions of a conditional sentence of imprisonment, and coercive treatment such as the ones provided through drug courts. Institutional constraint refers to any form of constraint exerted within any institutional setting, such as correctional facilities and programs offered in community. Correctional facilities being limited by their own specific mission, it might have a major impact on the way the objectives of treatment are defined. Those limitations can then be considered as a form of constraint, in which drug users don't have much space to express their personal needs. Finally, relational constraint refers to any form of constraint in

    2012-04-01

    Obesity is a significant health problem worldwide and is associated with a number of co-morbidities including type 2 diabetes mellitus, hypertension, dyslipidemia, obstructive sleep apnea, and cardiovascular disease. A number of different pathophysiologic mechanisms including increased inflammation, oxidative stress, and insulin resistance have been associated with initiation and progression of atherosclerotic disease in obese individuals. Lifestyle modifications have provided modest results in weight reduction and the focus of interest has now shifted towards drug development to treat severely obese individuals with a body mass index (BMI) >30 kg/m(2) or those with a BMI >27 kg/m(2) who have additional co-morbidities. Different regimens focusing on dietary absorption or acting centrally to control hunger and food intake have been developed. However, their weight loss effect is, in most cases, modest and this effect is lost once the medication is discontinued. In addition, long-term use of these drugs is limited by significant side effects and lack of long-term safety and efficacy data. Orlistat is the only US FDA-approved medication for long-term use. A number of new medications are currently under investigation in phase III trials with promising preliminary results. This review comments on available anti-obesity pharmacologic regimens, their weight-loss benefit, and their impact on cardiovascular risk factors.

    Full Text Available In this article we describe the key role of tuberculosis (TB treatment, the challenges (mainly the emergence of drug resistance, and the opportunities represented by the correct approach to drug dosage, based on the existing control and elimination strategies. In this context, the role and contribution of therapeutic drug monitoring (TDM is discussed in detail. Treatment success in multidrug-resistant (MDR TB cases is low (62%, with 7% failing or relapsing and 9% dying and in extensively drug-resistant (XDR TB cases is even lower (40%, with 22% failing or relapsing and 15% dying. The treatment of drug-resistant TB is also more expensive (exceeding €50 000 for MDR-TB and €160 000 for XDR-TB and more toxic if compared to that prescribed for drug-susceptible TB. Appropriate dosing of first- and second-line anti-TB drugs can improve the patient's prognosis and lower treatment costs. TDM is based on the measurement of drug concentrations in blood samples collected at appropriate times and subsequent dose adjustment according to the target concentration. The ‘dried blood spot’ technique offers additional advantages, providing the rationale for discussions regarding a possible future network of selected, quality-controlled reference laboratories for the processing of dried blood spots of difficult-to-treat patients from reference TB clinics around the world.

    Helicobacter pylori (H. pylori) is one of the most common pathogenic bacterial infections and is found in the stomachs of approximately half of the world's population. It is the primary known cause of gastritis, gastroduodenal ulcer disease and gastric cancer. However, combined drug therapy as the general treatment in the clinic, the rise of antibiotic-resistant bacteria, adverse reactions and poor patient compliance are major obstacles to the eradication of H. pylori. Oral site-specific drug delivery systems that could increase the longevity of the treatment agent at the target site might improve the therapeutic effect and avoid side effects. Gastroretentive drug delivery systems potentially prolong the gastric retention time and controlled/sustained release of a drug, thereby increasing the concentration of the drug at the application site, potentially improving its bioavailability and reducing the necessary dosage. Recommended gastroretentive drug delivery systems for enhancing local drug delivery include floating systems, bioadhesive systems and expandable systems. In this review, we summarize the important physiological parameters of the gastrointestinal tract that affect the gastric residence time. We then focus on various aspects useful in the development of gastroretentive drug delivery systems, including current trends and the progress of novel forms, especially with respect to their application for the treatment of H. pylori infections.

    In the last 2 decades, drug-resistant tuberculosis has become a threat and a challenge to worldwide public health. The diagnosis and treatment of these forms of tuberculosis are much more complex and prognosis clearly worsens as the resistance pattern intensifies. Nevertheless, it is important to remember that with the appropriatesystematic clinical management, most of these patients can be cured. These guidelines itemize the basis for the diagnosis and treatment of all tuberculosis patients, from those infected by strains that are sensitive to all drugs, to those who are extensively drug-resistant. Specific recommendations are given forall cases. The current and future role of new molecular methods for detecting resistance, shorter multi-drug-resistant tuberculosis regimens, and new drugs with activity against Mycobacterium tuberculosis are also addressed.

    Full Text Available The causes of drug abuse and criminal behavior are closely linked. Not surprisingly, there is a high percentage of prisoners who during sentence execution abuse or are dependent on drugs. Antisocial personality disorder can be considered a common predictor of committing criminal offenses and drug abuse. A review of studies has revealed a high prevalence of inmates who use drugs while serving a sentence. Also, prison environment represents only a new context of the continuum of drug abuse by inmates. There are different theoretical approaches in explaining this phenomenon. Treatment programs based on empirically validated principles that guarantee the effectiveness, may be one strategy for solving the problem of drug abuse in prisons, with multiple positive effects.

    Antiepileptic drug (AED) treatments produce inconsistent outcomes, often necessitating patients to go through several drug trials until a successful treatment can be found. This study proposes the use of machine learning techniques to predict epilepsy treatment outcomes of commonly used AEDs. Machine learning algorithms were trained and evaluated using features obtained from intracranial electroencephalogram (iEEG) recordings of the epileptiform discharges observed in Mecp2-deficient mouse model of the Rett Syndrome. Previous work have linked the presence of cross-frequency coupling (I CFC) of the delta (2-5 Hz) rhythm with the fast ripple (400-600 Hz) rhythm in epileptiform discharges. Using the I CFC to label post-treatment outcomes we compared support vector machines (SVMs) and random forest (RF) machine learning classifiers for providing likelihood scores of successful treatment outcomes. (a) There was heterogeneity in AED treatment outcomes, (b) machine learning techniques could be used to rank the efficacy of AEDs by estimating likelihood scores for successful treatment outcome, (c) I CFC features yielded the most effective a priori identification of appropriate AED treatment, and (d) both classifiers performed comparably. Machine learning approaches yielded predictions of successful drug treatment outcomes which in turn could reduce the burdens of drug trials and lead to substantial improvements in patient quality of life.

    Despite the increasing prevalence of drug-resistant tuberculosis, most low- and middle-income countries use standardized regimens, without assessment of drug susceptibility. To perform a systematic review and meta-analysis of the effect of initial drug resistance and treatment regimen on tuberculosis treatment outcomes. PubMed, the Cochrane Central Database of Clinical Trials, and EMBASE were searched for studies published in English from 1965 to June 2007. Additional studies were identified from cited references. Randomized, controlled trials and cohort studies of standardized treatment of previously untreated patients with culture-confirmed pulmonary tuberculosis. Drug-susceptibility testing was done on pretreatment isolates from all patients and from patients with treatment failure or relapse. Two authors reviewed the studies for methods, initial drug resistance, treatment regimens, and outcomes. Pooled cumulative incidences were computed with random-effects meta-analyses. Association between risk factors and outcomes were determined by using stratified analyses. The cumulative incidence of acquired drug resistance with initially pan-sensitive strains was 0.8% (95% CI, 0.5% to 1.0%) compared with 6% (CI, 4% to 8%) with initially single drug-resistant strains and 14% (CI, 9% to 20%) with initially polydrug-resistant strains. Failure and relapse were most strongly associated with initial drug resistance. Failure was also associated with shorter duration of rifampin therapy and nonuse of streptomycin, whereas the rate of relapse was higher with shorter duration of rifampin therapy and nonuse of pyrazinamide. Few studies included HIV-infected persons, and treatment outcomes were pooled despite considerable heterogeneity. Treatment outcomes were substantially worse in the presence of initial drug resistance, which has important implications in resource-limited settings in which drug resistance is prevalent.

    The aim of our study was to determine the effectiveness of using ultrasound (US) to increase the permeability of the nail, with the goal of improving outcomes in the treatment of onychomycosis. Porcine nails were used because of their similarity to human nails. A hydrophilic blue dye was used as a drug-mimicking compound. Two sets of experiments were performed: luminosity experiments to assess the dye levels inside the nail after US and sham treatments and diffusion cell experiments for determination of changes in nail permeability due to US application. In both sets of experiments, planar US transducers were used to sonicate the nails at frequencies of 400, 600, and 800 kHz and 1 MHz, an intensity of 1 W/cm 2 , and a duration of 5 min in a continuous mode. Modeling studies were also performed to assess the safety of US application to the human toe for later clinical studies. In the luminosity experiments, application of US at frequencies of 600 and 800 kHz led to statistically significant results (P nail of up to 95% compared to control values. The diffusion cell results found statistical significance (P nail permeability compared to the control. Safety modeling studies found a maximal temperature increase of 4.4 °C in the bone. Our proposed US method may offer an alternative for improved treatment of onychomycosis. The current maximal temperature increase was found to be at the safety limit, and so pulsing and other alternatives will be investigated to minimize this temperature increase. © 2017 by the American Institute of Ultrasound in Medicine.

    Thomas, Christopher A

    2011-10-01

    Hypertensive crisis is a relatively rare event and is associated with significant morbidity and mortality in adults and pediatric patients alike. Rapid, safe, and effective treatment is imperative to alleviate immediate presenting clinical symptoms, prevent devastating morbidity, preserve long-term quality of life, and prevent mortality. Many medications in the hypertensive crisis arsenal have been used for nearly half a century. Nearly all treatment options have been utilized in children for decades, yet reliable data and sound clinical literature remain elusive. Every agent considered to be a first-line, second-line, or adjunctive option has yet to be evaluated in a randomized controlled trial in pediatric patients. With a paucity of clinical data to form evidence-based decisions, the clinician must rely entirely on the extrapolation from adult data and small retrospective studies, case series, and case reports of medication use in pediatric patients. Although more research in the treatment of pediatric hypertensive crisis is desperately needed, current practice demands a sharp knowledge of the pediatric clinical literature and pharmacology in this area as an essential tool to consistently improve patient outcomes with respect to morbidity and mortality.

    To evaluate the role of herbal medicine in drug-induced parkinsonism (DIP) and identify an optimal treatment approach. Retrospective review of DIP cases treated with herbal medicine. The Parkinson's clinic at Kyung Hee Traditional Korean Medicine Hospital, Korea. Twenty-one patients whose clinical outcome and offending drug could be identified. Clinical features, treatments, and outcomes and summarized the clinical course and treatment in each case. Twelve patients had levosulpiride-induced parkinsonism and 9 had parkinsonism induced by another drug. The offending drugs were discontinued in all patients, and all patients received herbal medications during treatment. Nine of 12 patients with parkinsonism from levosulpiride and 4 of 9 patients with parkinsonism from other drugs had complete reversal of symptoms. The most frequently used herbal formula was Ukgansan (Yigansan). DIP in the levosulpiride group tended to improve faster with herbal medicine, and the percentage of improvement was higher. Optimal herbal medicine treatments chosen after a careful history and evaluation for risk factors may be helpful in reversing DIP.

  9. [Threshold of Application of Antidepressant Drugs for Treatment of Depressive Disorder].

    Kuroki, Toshihide; Tanaka, Teppei

    2015-01-01

    In recent years, along with the expansion of medical care for depressive disorder, there has been much controversy regarding the application of antidepressant drugs for its treatment. The aim of this paper is to consider critical issues concerning the threshold of application of antidepressant drugs for the treatment of depression. It was formerly important to diagnose the 'quality' of depression (melancholia or non-melancholia) in order to choose antidepressant treatment, whereas an assessment of the 'quantity' of depression (severity of symptoms) is crucial today to decide on the threshold. Recent guidelines for the treatment of major depressive disorder do not positively recommend the use of medication for the treatment of mild depression. The guidelines published by the Japanese Society of Mood Disorders also state that doctors have to give priority to treatments avoiding medication, although the effectiveness of antidepressant drugs for mild depression is controversial. Actually, in a clinical setting, doctors have to understand the conditions of individual cases and cope with many issues, such as a risk of suicide, comorbidity of other psychiatric disorders, target symptoms of pharmacotherapy, and choices of classes and doses of antidepressant drugs. The threshold of application of antidepressant drugs for the treatment of depression may vary according to the doctor-patient relationship and surrounding conditions. Doctors are required to provide treatment options other than pharmacotherapy.

    Advanced drug delivery systems (DDS) present indubitable benefits for drug administration. Over the past three decades, new approaches have been suggested for the development of novel carriers for drug delivery. In this review, we describe general concepts and emerging research in this field based on multidisciplinary approaches aimed at creating personalized treatment for a broad range of highly prevalent diseases (e.g., cancer and diabetes). This review is composed of two parts. The first part provides an overview on currently available drug delivery technologies including a brief history on the development of these systems and some of the research strategies applied. The second part provides information about the most advanced drug delivery devices using stimuli-responsive polymers. Their synthesis using controlled-living radical polymerization strategy is described. In a near future it is predictable the appearance of new effective tailor-made DDS, resulting from knowledge of different interdisciplinary sciences, in a perspective of creating personalized medical solutions.

    Amblyopia is a unilateral or bilateral reduction of visual acuity secondary to abnormal visual experience during early childhood. It is one of the most common causes of vision loss and monocular blindness and is commonly associated with strabismus, anisometropia, and visual deprivation (in particular congenital cataract and ptosis). It is clinically defined as a two-line difference of best-corrected visual acuity between the eyes. The purpose of this study was to understand the neural mechanisms of amblyopia and summarize the current therapeutic strategies. In particular, the authors focused on the concept of brain plasticity and its implication for new treatment strategies for children and adults with amblyopia. Copyright 2014, SLACK Incorporated.

    Full Text Available Backgrounds: Drug related problems can be defined as any event (or circumstance involving the drug treatment, which interferes or potentially interferes with the patient in achieving an optimum outcome of medical care. The aim of the study was to identify drug therapy problems and to assess the pharmacist interventions in patients with cardiovascular diseases.Methods: The inpatient case records including drug history and other relevant details of the admitted patients under the cardiology department were collected and reviewed by the clinical pharmacist for drug related problems. In case if any drug related problem was identified, was discussed with the concerned physician and suitable interventions was provided and documented.Results: A total of 112 patient case sheets were reviewed during the study period, out of which 53 drug related problems were identified from 44 patients. The most common drug related problem was found to be drug Interactions (49.05% followed by Adverse Drug Reaction (18.86%, and failure to receive drugs (9.43%. The most frequent suggestions provided by the intervening pharmacist were cessation of drug (24.52%, followed by Change in frequency of administration (22.64%, change in drug dose (20.75%. The majority of level of significance of drug related problems was seen to have moderate significance in grade. The acceptance rate of recommendations and change in drug therapy was found to be high (96.21%.Conclusion: The current study highlights the importance of a pharmacist in a multidisciplinary team of routinely reviewing the drug therapy for identification and resolution of drug related problems which helps in achieving better therapeutic outcomes and improved patient care.

    WHO estimates that 9 million people developed active tuberculosis in 2013 and 1·5 million people died from it. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis continue to spread worldwide with an estimated 480,000 new cases in 2013. Treatment success rates of MDR and XDR tuberculosis are still low and development of new, more effective tuberculosis drugs and adjunct therapies to improve treatment outcomes are urgently needed. Although standard therapy for drug-sensitive tuberculosis is highly effective, shorter, more effective treatment regimens are needed to reduce the burden of infectious cases. We review the latest WHO guidelines and global recommendations for treatment and management of drug-sensitive and drug-resistant tuberculosis, and provide an update on new drug development, results of several phase 2 and phase 3 tuberculosis treatment trials, and other emerging adjunct therapeutic options for MDR and XDR tuberculosis. The use of fluoroquinolone-containing (moxifloxacin and gatifloxacin) regimens have failed to shorten duration of therapy, and the new tuberculosis drug pipeline is sparse. Scale-up of existing interventions with increased investments into tuberculosis health services, development of new antituberculosis drugs, adjunct therapies and vaccines, coupled with visionary political leadership, are still our best chance to change the unacceptable status quo of the tuberculosis situation worldwide and the growing problem of drug-resistant tuberculosis.

  17. Combinations of drugs in the Treatment of Obesity

    Directory of Open Access Journals (Sweden)

    2010-07-01

    Full Text Available Obesity is a chronic disease associated with excess morbidity and mortality. Clinical treatment, however, currently offers disappointing results, with very high rates of weight loss failure or weight regain cycles, and only two drugs (orlistat and sibutramine approved for long-term use. Drugs combinations can be an option for its treatment but, although widely used in clinical practice, very few data are available in literature for its validation. Our review focuses on the rationale for their use, with advantages and disadvantages; on combinations often used, with or without studies; and on new perspectives of combinations being studied mainly by the pharmaceutical industry.

    Very high blood pressure during pregnancy poses a serious threat to women and their babies. The aim of antihypertensive therapy is to lower blood pressure quickly but safety, to avoid complications. Antihypertensive drugs lower blood pressure but their comparative effectiveness and safety, and impact on other substantive outcomes is uncertain. To compare different antihypertensive drugs for very high blood pressure during pregnancy. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (9 January 2013). Studies were randomised trials. Participants were women with severe hypertension during pregnancy. Interventions were comparisons of one antihypertensive drug with another. Two review authors independently assessed trials for inclusion and assessed trial quality. Two review authors extracted data and checked them for accuracy. Thirty-five trials (3573 women) with 15 comparisons were included. Women allocated calcium channel blockers were less likely to have persistent high blood pressure compared to those allocated hydralazine (six trials, 313 women; 8% versus 22%; risk ratio (RR) 0.37, 95% confidence interval (CI) 0.21 to 0.66). Ketanserin was associated with more persistent high blood pressure than hydralazine (three trials, 180 women; 27% versus 6%; RR 4.79, 95% CI 1.95 to 11.73), but fewer side-effects (three trials, 120 women; RR 0.32, 95% CI 0.19 to 0.53) and a lower risk of HELLP (haemolysis, elevated liver enzymes and lowered platelets) syndrome (one trial, 44 women; RR 0.20, 95% CI 0.05 to 0.81).Labetalol was associated with a lower risk of hypotension compared to diazoxide (one trial 90 women; RR 0.06, 95% CI 0.00 to 0.99) and a lower risk of caesarean section (RR 0.43, 95% CI 0.18 to 1.02), although both were borderline for statistical significance.Both nimodipine and magnesium sulphate were associated with a high incidence of persistent high blood pressure, but this risk was lower for nimodipine compared to magnesium sulphate (one trial

  19. From club drug to orphan drug: sodium oxybate (Xyrem) for the treatment of cataplexy.

    2003-09-01

    Narcolepsy, a rare disease with a prevalence of 0.05% in the general population, affects an estimated 140,000 patients in the United States. Patients have been able to lead fuller personal and professional lives since the Food and Drug Administration approved sodium oxybate (Xyrem) in 2002 for treatment of cataplexy in patients with narcolepsy. Previously, gamma-hydroxybutyrate (GHB), the active ingredient of sodium oxybate, had been a substance of abuse, most notoriously as a date-rape drug. Public Law 106-172, the date-rape prohibition act enacted in 2000, was modified to allow the drug to be legally administered for medical purposes. Because of the apprehension regarding the risk of possible drug diversion after the approval of sodium oxybate and concerns about safety, the Xyrem Risk Management Program was created. This program has been successful in satisfying the needs of patients and physicians while ensuring responsible distribution of the drug.

    The paper presents a recent Danish programme using exercise to alter the behaviour and body image of drug addicts. 38 participants (23 male and 15 female) took part in groups three times per week for a minimum of two to a maximum of six months. Self-reported data combined with the European Addiction Severity Index (EuropASI) collected at initial admission and in follow-up interviews included information on drug use, body image, self-confidence and motivation to change behaviour. The completion rate of the participants during the training period was on average 52%, which is considered as a success in treatments with drug abusers, usually characterized by a low compliance and commitment. The results of the participants who completed the programme (n = 20) showed an increased oxygen uptake of an average of 10%, improved self-reported quality of life and a higher energy level for the majority of the participants. The addicts obtained a better body image, became more sensitive to physical pain and disorders and reduced their drug intake during the training period. The long-term effect showed that five of the 20 abusers interviewed reported that they still had not taken drugs, 10 had downgraded their intake, four experienced no change at all and one died through an overdose. The results show that physical exercise can provide important support in the treatment of drug abuse and that the main problem is maintaining change in behaviour and peer group influence to ensure long-term change.

    2017-01-01

    This chapter summarizes recent developments in preclinical and clinical research on Chinese herbal medicines and their neurochemical mechanism of action for the treatment of drug addiction. We searched Chinese and English scientific literature and selected several kinds of Chinese herbal medicines that have beneficial effects on drug addiction. Ginseng (Renshen) may be clinically useful for the prevention of opioid abuse and dependence. Rhizoma Corydalis (Yanhusuo) may be used to prevent relapse to chronic drug dependence. Alkaloids of Uncaria rhynchophylla (Gouteng) appear to have positive effects on methamphetamine and ketamine addiction. Both Salvia miltiorrhiza (Danshen) and Radix Pueraiae (Gegen) have beneficial inhibitory effects on alcohol intake. Sinomenine has been shown to have preventive and curative effects on opioid dependence. l-Stepholidine, an alkaloid extract of the Chinese herb Stephania intermedia (Rulan), attenuated the acquisition, maintenance, and reacquisition of morphine-induced conditioned place preference and antagonized the heroin-induced reinstatement of heroin seeking. Traditional Chinese herbal medicines may be used to complement current treatments for drug addiction, including withdrawal and relapse. As the molecular mechanisms of action of traditional Chinese herbal medicines are elucidated, further advances in their use for the treatment of drug addiction are promising. © 2017 Elsevier Inc.

    Drug-resistant epilepsy affects 25% of all epileptic patients, and quality of life decreases in these patients due to their seizures. Early detection is crucial in order to establish potential treatment alternatives and determine if the patient is a surgical candidate. PubMed search for articles, recommendations published by major medical societies, and clinical practice guidelines for drug-resistant epilepsy and its medical and surgical treatment options. Evidence and recommendations are classified according to the criteria of the Oxford Centre for Evidence-Based Medicine (2001) and the European Federation of Neurological Societies (2004) for therapeutic actions. Identifying patients with drug-resistant epilepsy is important for optimising drug therapy. Experts recommend rational polytherapy with antiepileptic drugs to find more effective combinations with fewer adverse effects. When adequate seizure control is not achieved, a presurgical evaluation in an epilepsy referral centre is recommended. These evaluations explore how to resect the epileptogenic zone without causing functional deficits in cases in which this is feasible. If resective surgery is not achievable, palliative surgery or neurostimulation systems (including vagus nerve, trigeminal nerve, or deep brain stimulation) may be an option. Other treatment alternatives such as ketogenic diet may also be considered in selected patients. Copyright © 2014 Sociedad Española de Neurología. Published by Elsevier España, S.L.U.

    This review synthesizes available epidemiological data on current drug use and substance abuse treatment admissions in south africa since 1994, and how changes in the political, economic and social structures within south africa both before and after apartheid make the country more vulnerable to drug use. based on national surveys current use of cannabis ranged among adolescents from 2% to 9% and among adults 2%, cocaine/crack (0.3%), mandrax/sedatives (0.3%), club drugs/amphetamine-type stimulants (0.2%), opiates (0.1%) and hallucinogens (0.1%). The primary illicit substance at admission to South African drug treatment centers was cannabis 16.9%, methamphetamine (Tik) 12.8%, crack/cocaine 9.6%, cannabis and mandrax 3.4%, heroin/opiates 9.2%, and prescription and OTC 2.6%. An increase in substance abuse treatment admissions has occurred. While the prevalence of illicit drug use in South Africa is relatively low compared to the USA and Australia, prevention and intervention policies need to be designed to reduce these levels by targeting the more risky subpopulations identified from this review.

    Summers, Pamela; Alemu, Brook; Quidgley-Nevares, Antonio

    2015-01-01

    To determine reasons and describe characteristics of patients who violate their opioid treatment agreement. Cross-sectional retrospective study. New patients aged 18 years or above attending a multidisciplinary comprehensive pain management clinic from January 2012 to June 2012. Reason for discharge from the clinic. Of the 234 subjects in the study, 38.5 percent were discharged due to treatment agreement violation. A majority had a self-reported history of tobacco use, followed by alcohol and marijuana. The mean age of discharge was 45.1 years (SD 11.6) and they were discharged on average in 7.4 months after their first clinic visit. The primary reason for discharge was for an inappropriate urine drug screen (UDS) with illicit drug use being the most common at 40 percent and marijuana being the most common illicit drug. Subjects reporting a history of any drug use were nearly seven times more likely to be discharged. Hydrocodone was the most common nonprescribed opioid found in the UDS for those discharged for using nonprescribed opioids. Inappropriate UDS is a main factor for discharge due to violation of the opioid treatment agreement. Those with self-reported current or prior drug use were more likely to be discharged from the clinic.

  8. Drug rechallenge and treatment beyond progression—implications for drug resistance

    The established dogma in oncology for managing recurrent or refractory disease dictates that therapy is changed at disease progression, because the cancer is assumed to have become drug-resistant. Drug resistance, whether pre-existing or acquired, is largely thought to be a stable and heritable process; thus, reuse of therapeutic agents that have failed is generally contraindicated. Over the past few decades, clinical evidence has suggested a role for unstable, non-heritable mechanisms of acquired drug resistance pertaining to chemotherapy and targeted agents. There are many examples of circumstances where patients respond to reintroduction of the same therapy (drug rechallenge) after a drug holiday following disease relapse or progression during therapy. Additional, albeit limited, evidence suggests that, in certain circumstances, continuing a therapy beyond disease progression can also have antitumour activity. In this Review, we describe the anticancer agents used in these treatment strategies and discuss the potential mechanisms explaining the apparent tumour re-sensitization with reintroduced or continued therapy. The extensive number of malignancies and drugs that challenge the custom of permanently switching to different drugs at each line of therapy warrants a more in-depth examination of the definitions of disease progression and drug resistance and the resulting implications for patient care.

  9. Treatment Approaches for Interoceptive Dysfunctions in Drug Addiction

    Directory of Open Access Journals (Sweden)

    Martin P Paulus

    2013-10-01

    Full Text Available There is emerging evidence that individuals with drug addiction have dysfunctions in brain systems that are important for interoceptive processing, which include, among others, the insular and the anterior cingulate cortices. These individuals may not be expending sufficient neural resources to process perturbations of the interoceptive state but may exert over-activation of these systems when processing drug-related stimuli. As a consequence, insufficient detection and processing of interoceptive state changes may result in inadequate anticipation and preparation to adapt to environmental challenges, e.g. adapt to abstinence in the presence of withdrawal symptoms. Here, we integrate interoceptive dysfunction in drug-addicted individuals, with the neural basis for meditation and exercise to develop a heuristic to target the interoceptive system as potential treatments for drug addiction. First, it is suggested that mindfulness-based approaches can modulate both interoceptive function and insular activation patterns. Second, there is an emerging literature that the regulation of physical exercise in the brain involves the insula and anterior cingulate cortex and that intense physical exercise is associated with a state-dependent activation difference in the insula that may provide a window to attenuate the increased interoceptive response drug related stimuli. It is concluded that the conceptual framework of interoceptive dysfunctions in drug addiction and the experimental findings in meditation and exercise provide a useful approach to develop new interventions for drug addiction.

    There is emerging evidence that individuals with drug addiction have dysfunctions in brain systems that are important for interoceptive processing, which include, among others, the insular and the anterior cingulate cortices. These individuals may not be expending sufficient neural resources to process perturbations of the interoceptive state but may exert over-activation of these systems when processing drug-related stimuli. As a consequence, insufficient detection and processing of interoceptive state changes may result in inadequate anticipation and preparation to adapt to environmental challenges, e.g., adapt to abstinence in the presence of withdrawal symptoms. Here, we integrate interoceptive dysfunction in drug-addicted individuals, with the neural basis for meditation and exercise to develop a heuristic to target the interoceptive system as potential treatments for drug addiction. First, it is suggested that mindfulness-based approaches can modulate both interoceptive function and insular activation patterns. Second, there is an emerging literature showing that the regulation of physical exercise in the brain involves the insula and anterior cingulate cortex and that intense physical exercise is associated with a insula changes that may provide a window to attenuate the increased interoceptive response to drug-related stimuli. It is concluded that the conceptual framework of interoceptive dysfunctions in drug addiction and the experimental findings in meditation and exercise provide a useful approach to develop new interventions for drug addiction.

    Fibromyalgia (FM) is a chronic disorder whose symptoms of pain, fatigue, sleep disturbances and depression have a devastating effect on patients' lives as it limits their ability to engage in everyday working and social activities, and make it difficult to maintain normal relationships with family, friends and employers. None of the currently available drugs are fully effective against the whole spectrum of symptoms. The aim of this narrative review is to summarise the data relating to the new therapeutic options that have become available over the last few years. Areas covered: Increasing efforts by the pharmaceutical industry have led to the introduction of new investigational drugs and new formulations of older drugs, and studies have been carried out in order to investigate the possibility of using drugs that are currently used for other diseases. Expert opinion: Slight improvements in the health of FM patients treated with drugs targeting a range of molecular mechanisms have been observed, but there is still no single drug that is capable of offering substantial efficacy against all of the characteristic symptoms of FM. The identification of new and improved therapies for FM requires consideration of the heterogeneity of the condition, which suggests the existence of different patient subgroups, a relationship between central and peripheral aspects of the pathophysiology, and the need for combined treatment with drugs targeting multiple molecular mechanisms.

  13. Significance and challenges of stereoselectivity assessing methods in drug metabolism

    2016-02-01

    Full Text Available Stereoselectivity in drug metabolism can not only influence the pharmacological activities, tolerability, safety, and bioavailability of drugs directly, but also cause different kinds of drug–drug interactions. Thus, assessing stereoselectivity in drug metabolism is of great significance for pharmaceutical research and development (R&D and rational use in clinic. Although there are various methods available for assessing stereoselectivity in drug metabolism, many of them have shortcomings. The indirect method of chromatographic methods can only be applicable to specific samples with functional groups to be derivatized or form complex with a chiral selector, while the direct method achieved by chiral stationary phases (CSPs is expensive. As a detector of chromatographic methods, mass spectrometry (MS is highly sensitive and specific, whereas the matrix interference is still a challenge to overcome. In addition, the use of nuclear magnetic resonance (NMR and immunoassay in chiral analysis are worth noting. This review presents several typical examples of drug stereoselective metabolism and provides a literature-based evaluation on current chiral analytical techniques to show the significance and challenges of stereoselectivity assessing methods in drug metabolism.

  14. Chemical dependency treatment: the integration of the alcoholism and drug addiction/use treatment systems.

    Science.gov (United States)

    Rawson, R A

    The development of the alcoholism and drug addiction/use treatment systems was completely separate. By 1980, the drug addiction/use field had a solid scientific base but was losing momentum as a public priority. The alcoholism treatment system was gaining acceptance and the 28-day hospital was becoming the treatment standard. During the 1980s the cocaine epidemic, the AIDS crisis, and major health care financing shifts brought new currents of change into the system. By the end of the decade, the alcoholism system and drug addiction/use system were extremely out of sync. To maximize the information that each field has to offer the other and to coordinate the treatment effort, a single chemical dependency treatment system is proposed. This development would require the integration of the NIAAA and NIDA. The result would promote the establishment of coordinated treatment standards and subsequent improvement of treatment based upon empirical decision making.

    Available anti-obesity pharmacotherapy options remain very limited. The development of more effective drugs has become a priority. The potential strategies to achieve weight loss are to reduce energy intake, by stimulating anorexigenic signals or by blocking orexigenic signals, and to increase energy expenditure. This review will focus on approved obesity medications, as well as potential new pharmacological treatment options.

    Purgato, M; Gastaldon, C; Papola, D; Magni, L R; Rossi, G; Barbui, C

    2015-06-01

    This study aimed at investigating whether dose is a mediator of treatment effect in fluoxetine-randomized trials. Specifically, we investigated whether dose was higher in trials in which the aim was to demonstrate fluoxetine efficacy in comparison with older antidepressants and lower in trials in which the aim was to demonstrate a new drug's efficacy against fluoxetine. We applied the model developed by Baron and Kenny to investigate the mediational role of drug dose on treatment effect. We included all randomized controlled trials comparing fluoxetine with other antidepressants as monotherapy in the acute-phase treatment of unipolar major depression. A total of 173 studies were included. In 76 comparisons (44%), fluoxetine was the experimental antidepressant. A metaregression analysis indicated that after adjusting for possible confounders, studies where fluoxetine was the experimental agent were associated with a significant advantage for fluoxetine. However, the Baron and Kenny model revealed no mediational role of drug dose in influencing treatment effect. The outcome of fluoxetine-randomized trials changed according to whether this drug was used as a new compound or as a reference. This finding cannot be attributed to antidepressants dose, as dose failed to emerge as mediator of treatment effect in the Baron and Kenny approach. © 2014 John Wiley & Sons A/S.

    To assess the incidence of postoperative complications, blood transfusions and survival at one month, in the old patients operated for hip fracture undergoing chronic treatment with antiplatelet drugs. Two hundred twenty three patients operated for hip fracture were studied retrospectively, separated into 3 groups: patients who received acetylsalicylic acid (group I), patients who were given 100mg/day of acetylsalicylic acid or 300mg/day of triflusal (group II) and patients receiving>100mg/day of acetylsalicylic acid, or>300mg/day of triflusal or thienopyridines (group III). Surgery was delayed for 4 days in patients in group III. Demographic, biological, clinical and treatment characteristics, postoperative complications and survival at one month were recorded. Patients in group III were older and sustain worse general health status. Patients with a higher transfusion requirement were those of group II (73.8%) (P=0.192), who also showed a higher percentage of anaemia on admission. Severe cardiovascular complications were experienced by 5.4% of group III patients, 4.8% of group II patients and 2.1% of group I patients. Patients from group III presented a significant amount of respiratory complications (P=0.007). Our results suggest that delaying surgery for 4 days in patients treated with clopidogrel can be associated to an increase in postoperative respiratory complications and severe adverse cardiovascular events, without increasing the tranfusional index, hospital stay, mortality, and without complications related to neuraxial anaesthesia.

    The majority of patients enrolled in treatment for substance use disorders (SUDs) also use tobacco. Many will continue to use tobacco even during abstinence from other drugs and alcohol, often leading to smoking-related illnesses. Despite this, little research has been conducted to assess the influence of being a smoker on SUD treatment outcomes and changes in smoking during a treatment episode. In this secondary analysis, cigarette smoking was evaluated in participants completing outpatient SUD treatment as part of a multi-site study conducted by the National Drug Abuse Treatment Clinical Trials Network. Analyses included the assessment of changes in smoking and nicotine dependence via the Fagerström Test for Nicotine Dependence during the 12-week study among all smokers (aim #1), specifically among those in the experimental treatment group (aim #2), and the moderating effect of being a smoker on treatment outcomes (aim #3). Participants generally did not reduce or quit smoking throughout the course of the study. Among a sub-set of participants with higher baseline nicotine dependence scores randomized to the control arm, scores at the end of treatment were lower compared to the experimental arm, though measures of smoking quantity did not appear to decrease. Further, being a smoker was associated with poorer treatment outcomes compared to non-smokers enrolled in the trial. This study provides evidence that patients enrolled in community-based SUD treatment continue to smoke, even when abstaining from drugs and alcohol. These results add to the growing literature encouraging the implementation of targeted, evidence-based interventions to promote abstinence from tobacco among SUD treatment patients.

    2009-06-01

    This study examined the predictors of treatment completion among 380 state parole violators consecutively admitted to a comprehensive 12-month drug treatment program in lieu of reincarceration. Offenders were placed on intensive parole supervision throughout the 12-month treatment protocol and received three months of residential substance abuse treatment followed by nine months of outpatient counseling. Overall 123 (32.4%) of the offenders completed the 12-month treatment protocol. The primary reason for noncompletion was a positive drug screen. Bivariate analyses were performed to determine independent predictors of program completion. Four variables (age, past 30-day heroin use, total months incarcerated, and significant problems with mother) from the baseline Addiction Severity Index were found to be correlated with treatment completion (p <.10). These factors and other demographics (race, marital status, education) and variables found predictive of program completion in previous studies were entered into a multiple logistic regression model. Overall the final model found that only two factors--older age (p < .03) and no heroin use in the past 30 days (p < .02) significantly predicted treatment completion. These findings suggest that among parolees with moderate to extensive criminal justice histories younger individuals and those with recent heroin use respond less favorably to comprehensive substance abuse treatment services and intensive parole supervision.

  6. Bisphosphonate Treatment in Osteoporosis: Optimal Duration of Therapy and the Incorporation of a Drug Holiday.

    Bisphosphonates are the most widely used treatment for osteoporosis. They accumulate in the bone for years, and therefore, their inhibitory effects on osteoclasts may persist after drug discontinuation. The ideal duration of therapy remains controversial. The purpose of this study is to review the literature to determine the (1) indications for drug holiday, (2) the duration of drug holiday, (3) the evaluation during drug holiday, and (4) the proper treatment and maintenance after drug holiday. A review of two electronic databases (PubMed/MEDLINE and EMBASE) was conducted using the term "(Drug holiday)," in January 29, 2015. Inclusion criteria were as follows: (1) clinical trials and case control, (2) human studies, (3) published in a peer-review journal, and (4) written in English. Exclusion criteria were as follows: (1) case reports, (2) case series, and (3) in vitro studies. The literature supports a therapeutic pause after 3-5 years of bisphosphonate treatment in patients with minor bone deficiencies and no recent fragility fracture (low risk) and in patients with moderate bone deficiencies and/or recent fragility fracture (moderate risk). In these patients, a bone health reevaluation is recommended every 1-3 years. Patients with high fracture risk should be maintained on bisphosphonate therapy without drug holiday. The duration and length of drug holiday should be individualized for each patient. Evaluation should be based on serial bone mass measurements, bone turnover rates, and fracture history evaluation. If after drug therapy, assessments show an increased risk of fracture, the patient may benefit from initiating another treatment. Raloxifene, teriparatide, or denosumab are available options.

  7. Costs of drug delivery for CHOP, COP/CVP, and fludarabine: an international assessment.

    Herold, Michael; Hieke, Klaus

    2003-01-01

    The purpose of this analysis was to assess the real-life direct costs of drug delivery for frequently used chemotherapeutic regimens in patients with relapsed low-grade non-Hodgkin's lymphoma (NHL). This was a retrospective analysis of direct costs of drug delivery (acquisition plus administration) of relapsed low-grade NHL in 424 patients in Canada, Germany, and Italy. Results were expressed as an average treatment cost per patient for six cycles of chemotherapy. Exchange rates used were $1 (Canada)= currency 0.672, 1 DM (Germany)= currency 0.511, and 1 Lit (Italy)= currency 0.000517. Direct costs of drug delivery were greater for inpatients receiving fludarabine (Canada currency 12,669; Italy currency 13,027) than for CHOP (Canada currency 7856; Germany currency 7218; Italy currency 4251) or COP/CVP (Canada currency 7360; Germany currency 8449). Treatment administration setting was a major cost driver with inpatient treatment up to 9-fold more expensive than the same regimen given to outpatients. Drug administration costs comprised the largest proportion of the total for each regimen in the inpatient setting (69-98%). Costs of drug delivery in the outpatient setting were 10% to 65% of those in the inpatient setting. Again, fludarabine was more expensive (Italy currency 8493; Canada currency 7269) than CHOP (Canada currency 4403; Germany currency 2150; Italy currency 1264) and COP/CVP (Canada currency 3009; Germany currency 867). Administration costs were 2.5- to 15-fold higher for inpatients compared to outpatients. Costs of drug administration are a major driver for total direct treatment costs in the treatment of relapsed low-grade NHL and are at least as important as drug acquisition costs. Drug administration practices, in terms of inpatient or outpatient treatment, are a major factor in determining overall direct costs. Therapeutic strategies, which offer shortened treatment duration and/or a simple mode of administration, are likely to be economically

  9. Evaluation of the Drug Treatment and Persistence of Onychomycosis

    Full Text Available Onychomycosis is a common nail disease responsible for approximately 50% of diseases of the nail. It occurs more in the elderly, though several cases have been reported among children. Several factors influence, such as climate, geography, and migration. The two dermatophytes most commonly implicated in onychomycosis are Trichophyton rubrum and T. mentagrophytes, accounting for more than 90% of onychomycoses. Nonetheless, several other toxigenic molds have been implicated. For convenience, onychomycosis is divided into four major clinical presentations: distal subungal, which is the most common form of the disease; proximal subungal, which is the most common form found in patients with human immunodeficiency virus infection; superficial; and total dystrophic onychomycosis. Epidemiology of onychomycosis in adults and children is evaluated and the most common clinical symptoms addressed. Although the risk factors are discussed, the multifactorial nature of onychomycosis makes this inexhaustible. The diagnosis and treatments are difficult and the choice of appropriate antifungal drugs complex and require the knowledge of the chemical structures of the metabolites of the molds that cause onychomycosis and their interaction with the antifungal drugs. This is true because most of the antifungal drugs are derived from mold/fungal metabolism. Treatment with griseofulvin and amphotericin is displaced by the use of newer drugs from azole compounds, pyrimidines, and allylamines derivatives. Amorolfine, itraconazole, and ciclopirox nail lacquer solution 8 have gained support globally, but the side effects, drug resistance, and persistence of the disease are still a serious concern to the patients, just as economics and quality of life. Hence, the search for safer and more efficacious drug treatments are continuing.

    Full Text Available Schistosomiasis is a parasitic disease that, according to the World Health Organization, constitutes a major public health problem associated with severe morbidity, mostly children in preschool age. The administration of drugs in children always constitutes a difficult task, especially when formulations are not developed specifically for pediatric use, when high doses of drug are required and the drug has a bitter taste, as in the case of praziquantel. Polymer nanoparticles are promising systems for development of encapsulated drugs with low water solubility and bitter taste, due to the good physical and chemical stability, adequate biocompatibility and simple manufacturing processes. Moreover, they can enhance the bioavailabili-ty and reduce variability of treatment among patients. Poly (methyl methacrylate doped with praziquantel was produced through a miniemulsion polymerization pro-cess to compose a pediatric pharmaceutical suspension. Nanoparticles were cha-racterized in terms of physico-chemical properties, toxicological properties and biological activity in mice, being concluded that obtained results were satisfactory. The results were encapsulation rate around 90%, absence of chemical interaction drug - polymer and the presence of biological activity. A collaborative approach was used for this development, involving national partnerships and independent funding mechanisms, a powerful pathway for development of drugs for neglected diseases.

  11. Drug Discovery of Host CLK1 Inhibitors for Influenza Treatment

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available The rapid evolution of influenza virus makes antiviral drugs less effective, which is considered to be a major bottleneck in antiviral therapy. The key proteins in the host cells, which are related with the replication cycle of influenza virus, are regarded as potential drug targets due to their distinct advantage of lack of evolution and drug resistance. Cdc2-like kinase 1 (CLK1 in the host cells is responsible for alternative splicing of the M2 gene of influenza virus during influenza infection and replication. In this study, we carried out baculovirus-mediated expression and purification of CLK1 and established a reliable screening assay for CLK1 inhibitors. After a virtual screening of CLK1 inhibitors was performed, the activities of the selected compounds were evaluated. Finally, several compounds with strong inhibitory activity against CLK1 were discovered and their in vitro anti-influenza virus activities were validated using a cytopathic effect (CPE reduction assay. The assay results showed that clypearin, corilagin, and pinosylvine were the most potential anti-influenza virus compounds as CLK1 inhibitors among the compounds tested. These findings will provide important information for new drug design and development in influenza treatment, and CLK1 may be a potent drug target for anti-influenza drug screening and discovery.

    The use of cardiovascular drugs is related to the development of adverse drug reactions (ADRs) in about 24% of the patients in the Cardiovascular Care Unit. Here, we evaluated the ADRs in patients treated with antihypertensive drugs. The study was conducted in two phases: In the first phase, we performed a retrospective study on clinical records of Clinical Divisions (i.e., Internal Medicine Operative Unit and Geriatric Operative Unit) from January 1, 2012 to December 31, 2012. Moreover from January 1, 2013 to March 30, 2013 we performed a prospective study on the outpatients attending the Emergency Department (ED) of the Pugliese-Ciaccio Hospital of Catanzaro, by conducting patient interviews after their informed consent was obtained. The association between a drug and ADR was evaluated using the Naranjo scale. We recorded 72 ADRs in the Clinical Divisions and six in the ED, and these were more frequent in women. Using the Naranjo score, we showed a probable association in 92% of these reactions and a possible association in 8%. The most vulnerable age group involved in ADRs was that of the elderly patients. In conclusion, our results indicate that antihypertensive drugs may be able to induce the development of ADRs, particularly in elderly women receiving multiple drug treatment. Therefore, it is important to motivate the healthcare providers to understand their role and responsibility in the detection, management, documentation, and reporting of ADRs, as also all the essential activities for optimizing patient safety.

  14. Eating disorders: assessment and treatment.

    Johnson, W G; Schlundt, D G

    1985-09-01

    Anorexia and bulimia are eating disorders affecting a significant number of adolescent and young adult women. The core symptoms of both disorders are similar and include a fear of obesity, body image disturbance, erratic eating patterns, and purging. These symptoms produce significant physical and psychologic complications. Both anorexia and bulimia appear to have a common origin in a fear of obesity and dieting. Anorectics, being "successful" dieters, lose a significant amount of weight; whereas bulimics alternate between binges and purges. Treatment for the eating disorders is gradually evolving as clinical research experience accumulates. For anorexia, hospitalization is indicated when weight falls below 15% of ideal, and most investigators agree that therapy for the core symptoms cannot be undertaken until weight is restored. During the impatient stay, a behavior modification program can effectively organize medical, nutritional, and psychologic support, and offers the quickest and most direct route to weight restoration. The nasogastric tube and total parenteral nutrition are used primarily for those who are severely emaciated or who actively resist standard modes of therapy. Inpatient treatment is most effectively and efficiently rendered in a specialized eating disorder unit. Once weight restoration is progressing, behavior therapy for core symptoms is commenced and continued on an outpatient basis. A variety of behavioral techniques are employed, and they are designed primarily to influence anorectic assumptions and beliefs. Although there may be a brief inpatient stay for initiation of treatment, the bulk of therapy for bulimia occurs on an outpatient basis. The available literature indicates that behavioral techniques and antidepressant medication are effective for the symptoms of bulimia. Early identification of core symptoms of both disorders can lead to an initiation of treatment before the core symptoms become ingrained. A potentially more effective

    Full Text Available Abstract Background Previous studies have assessed the validity of the observational study design by comparing results of studies using this design to results from randomized controlled trials. The present study examined design features of observational studies that could have influenced these comparisons. Methods To find at least 4 observational studies that evaluated the same treatment, we reviewed meta-analyses comparing observational studies and randomized controlled trials for the assessment of medical treatments. Details critical for interpretation of these studies were abstracted and analyzed qualitatively. Results Individual articles reviewed included 61 observational studies that assessed 10 treatment comparisons evaluated in two studies comparing randomized controlled trials and observational studies. The majority of studies did not report the following information: details of primary and ancillary treatments, outcome definitions, length of follow-up, inclusion/exclusion criteria, patient characteristics relevant to prognosis or treatment response, or assessment of possible confounding. When information was reported, variations in treatment specifics, outcome definition or confounding were identified as possible causes of differences between observational studies and randomized controlled trials, and of heterogeneity in observational studies. Conclusion Reporting of observational studies of medical treatments was often inadequate to compare study designs or allow other meaningful interpretation of results. All observational studies should report details of treatment, outcome assessment, patient characteristics, and confounding assessment.

  18. Enhanced transmission of drug-resistant parasites to mosquitoes following drug treatment in rodent malaria.

    Directory of Open Access Journals (Sweden)

    Andrew S Bell

    Full Text Available The evolution of drug resistant Plasmodium parasites is a major challenge to effective malaria control. In theory, competitive interactions between sensitive parasites and resistant parasites within infections are a major determinant of the rate at which parasite evolution undermines drug efficacy. Competitive suppression of resistant parasites in untreated hosts slows the spread of resistance; competitive release following treatment enhances it. Here we report that for the murine model Plasmodium chabaudi, co-infection with drug-sensitive parasites can prevent the transmission of initially rare resistant parasites to mosquitoes. Removal of drug-sensitive parasites following chemotherapy enabled resistant parasites to transmit to mosquitoes as successfully as sensitive parasites in the absence of treatment. We also show that the genetic composition of gametocyte populations in host venous blood accurately reflects the genetic composition of gametocytes taken up by mosquitoes. Our data demonstrate that, at least for this mouse model, aggressive chemotherapy leads to very effective transmission of highly resistant parasites that are present in an infection, the very parasites which undermine the long term efficacy of front-line drugs.

    Mirabegron is the first drug in a new class of oral therapy for overactive bladder (OAB). It is a beta-3 adrenergic agonist, a class of drugs for the first time used for the treatment of urination disorders. Recently, following many years of rigorous multicenter randomized trials mirabegron has been approved for use in Europe and North America. The clinical indication for mirabegron is overactive bladder with symptoms of urge urinary incontinence, urgency, and urinary frequency and other storage symptoms in both men and women. Mirabegron is used in primary patients, or in patients who previously were unsuccessfully treated with anticholinergics. The drug has a good safety profile and causes no side effects typical of anticholinergics.

    Wound healing can be characterized as underhealing, as in the setting of chronic wounds, or overhealing, occurring with hypertrophic scar formation after burn injury. Topical therapies targeting specific biochemical and molecular pathways represent a promising avenue for improving and, in some cases normalizing, the healing process. A brief overview of both normal and pathological wound healing has been provided, along with a review of the current clinical guidelines and treatment modalities for chronic wounds, burn wounds and scar formation. Next, the major avenues for wound healing drugs, along with drugs currently in development, are discussed. Finally, potential challenges to further drug development, and future research directions are discussed. The large body of research concerning wound healing pathophysiology has provided multiple targets for topical therapies. Growth factor therapies with the ability to be targeted for localized release in the wound microenvironment are most promising, particularly when they modulate processes in the proliferative phase of wound healing.

  1. Drug Delivery Implants in the Treatment of Vitreous Inflammation

    Full Text Available The eye is a model organ for the local delivery of therapeutics. This proves beneficial when treating vitreous inflammation and other ophthalmic pathologies. The chronicity of certain diseases, however, limits the effectiveness of locally administered drugs. To maintain such treatments often requires frequent office visits and can result in increased risk of infection and toxicity to the patient. This paper focuses on the implantable devices and particulate drug delivery systems that are currently being implemented and investigated to overcome these challenges. Implants currently on the market or undergoing clinical trials include those made of nonbiodegradable polymers, containing ganciclovir, fluocinolone acetonide, triamcinolone acetonide, and ranibizumab, and biodegradable polymers, containing dexamethasone, triamcinolone acetonide, and ranibizumab. Investigational intravitreal implants and particulate drug delivery systems, such as nanoparticles, microparticles, and liposomes, are also explored in this review article.

    Although imaging studies in and of themselves have significant contributions to the study of human behavior, imaging in drug abuse has a much broader agenda. Drugs of abuse bind to molecules in specific parts of the brain in order to produce their effects. Positron emission tomography (PET) provides a unique opportunity to track this process, capturing the kinetics with which an abused compound is transported to its site of action. The specific examples discussed here were chosen to illustrate how PET can be used to map the regional distribution and kinetics of compounds that may or may not have abuse liability. We also discussed some morphological and functional changes associated with drug abuse and different stages of recovery following abstinence. PET measurements of functional changes in the brain have also led to the development of several treatment strategies, one of which is discussed in detail here. Information such as this becomes more than a matter of academic interest. Such knowledge can provide the bases for anticipating which compounds may be abused and which may not. It can also be used to identify biological markers or changes in brain function that are associated with progression from drug use to drug abuse and also to stage the recovery process. This new knowledge can guide legislative initiatives on the optimal duration of mandatory treatment stays, promoting long-lasting abstinence and greatly reducing the societal burden of drug abuse. Imaging can also give some insights into potential pharmacotherapeutic targets to manage the reinforcing effects of addictive compounds, as well as into protective strategies to minimize their toxic consequences.

    The relationship to treatment outcome, as measured by reduction in drug use, of specific characteristics and elements of 30 drug-free outpatient programs for adolescents is reported. Admission and discharge data were obtained from National Institute on Drug Abuse-Client Oriented Data Acquisition Process on 5789 adolescents in the 30 programs. A partial cross-validation study was conducted by analyzing separately for two annual client subsamples. The program, not the individual clients, was the unit of analysis. While controlling for differences between programs on their client populations, multiple regression analysis indicated that the following characteristics of programs were found to predict the outcome criterion variable, to a statistically significant degree: treat a large number of adolescent clients; have a special school for school dropouts; have a relatively large budget; employ counselors or therapists who have at least 2 years' experience in working with adolescent drug abusers; provide special services such as vocational counseling, recreational services, and birth control services; use such therapy methods as crisis intervention, gestalt therapy, music/art therapy, and group confrontation; and be perceived by the clients as allowing and encouraging free expression and spontaneous action by clients. There was a high degree of replication of these findings across the two annual subsamples of clients; and the amount of variance in the treatment outcome criterion variable accounted for by the above-listed program characteristics was quite impressive.

    Glutamate plays a pivotal role in drug addiction, and the N-methyl-D-aspartate (NMDA) glutamate receptor subtype serves as a molecular target for several drugs of abuse. In this review, we will provide an overview of NMDA receptor structure and function, followed by a review of the mechanism of action, clinical efficacy, and side effect profile of NMDA receptor ligands that are currently in use or being explored for the treatment of drug addiction. These ligands include the NMDA receptor modulators memantine and acamprosate, as well as the partial NMDA agonist D-cycloserine. Data collected to date suggest that direct NMDA receptor modulators have relatively limited efficacy in the treatment of drug addiction, and that partial agonism of NMDA receptors may have some efficacy with regards to extinction learning during cue exposure therapy. However, the lack of consistency in results to date clearly indicates that additional studies are needed, as are studies examining novel ligands with indirect mechanisms for altering NMDA receptor function.

    Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice and a difficult-to-treat arrhythmia. Conventional antiarrhythmic drugs, including flecainide, propafenone, sotalol and amiodarone, have several limitations in terms of efficacy and tolerability, and have made new drug development crucial. In the last decade, intensive research was undertaken to find new pharmacological options for the treatment of AF, and two new drugs are now available. Vernakalant is an atrial-selective drug specifically designed to block sodium channels at the atrial level, and its intravenous formulation has recently been recommended for approval by the Food and Drug Administration for pharmacological conversion of AF. Dronedarone is a chemical derivative of amiodarone (though having a significantly different clinical profile) with effects on multiple ion channels that proved effective in reducing the rate of the combined endpoint of death from any cause and cardiovascular hospitalization in patients with non-permanent AF enrolled in the ATHENA study. The available evidence on the efficacy of dronedarone has led to approval for recommendation in many clinical situations in which rhythm control is desirable. The complexity of the mechanisms underlying AF and the large variability of associated comorbidities render the AF patient a unique entity, making the identification of patients who may benefit from these novel approaches challenging.

    To assess the impact of physician awareness to promote the prescription and the dispensing of generic drugs at hospital discharge. The study consisted in a Before/After Study design including the analysis of medical prescriptions at hospital discharge, after a pharmaceutical intervention to physicians in a geriatric ward. Each drug was classified according to its terms of prescribing (International Nonproprietary Name (INN), Generic or Trade Name). The primary endpoint defined is the rate of medication prescribed by INN or generic. Statistical analysis was performed on all medicines and according to the prescribers' status (junior/senior). Three hundred and fifty one drugs were prescribed in the group "before intervention" versus 301 in the group "after". The average number of drugs prescribed per patient was similar between the two groups (9.5 drugs/patient). A generic prescription has been improved by 5% between the two periods (19.7% "before" vs 24.3% "after", p=0.27). Analysis on prescriber status indicates that the pharmaceutical intervention had a significant impact on junior physicians, which resulted in improved prescribing of drug (INN or generic) from 17.6% to 31.4% between the two periods (p=0.006). The pharmaceutical intervention to physicians has led to an improvement of drug prescription (INN or generic) at hospital discharge. This awareness has affected mainly junior prescribers hence the need to extend this type of intervention to all prescribers of our establishment.

    Men who are violent toward their partners tend to have a dual problem with alcohol and drug use, yet little is known about differences between men with single rather than dual problems. This study was one of the first to evaluate differences between alcohol dependent men who were arrested for Intimate Partner Violence (IPV) with and without concurrent illicit drug use. Seventy-eight participants were randomly assigned to manual-guided group behavioral therapies (Cognitive Behavioral Therapy or Twelve Step Facilitation) and assessed across 12 weeks of treatment. Despite denying drug use at baseline, thirty-two clients (43%) tested positive for illicit drug use (cocaine and marijuana) during the 12 weeks of treatment. The study specifically addressed whether there were differences between clients using alcohol only versus individuals using both alcohol + drugs in terms of 1) baseline characteristics; 2) treatment compliance (e.g., attendance and substance use during treatment; and 3) treatment outcomes (alcohol, drug use, anger management, and aggression at the completion of treatment). The results showed that there were comparatively few differences between the alcohol versus the alcohol + drug using groups at baseline. Regarding treatment compliance and retention, alcohol + drug using participants attended significantly fewer sessions, had significantly fewer percent days abstinence from alcohol use, significantly more total days of positive breathalyzer results. Regarding treatment outcomes across anger management and aggression scores, the alcohol + drug using participants had significantly more impairments in anger management styles from pre- to post-treatment. However, there were no differences between the groups across verbal or physical aggression. Both groups improved in their verbal aggression from pre- to post-treatment. The findings suggest that alcohol dependent men who continue to use illicit drugs may require additional interventions to effectively

    Pradigastat, a novel diacylglycerol acyltransferase-1 inhibitor, has activity in common metabolic diseases associated with abnormal accumulation of triglycerides. In vitro studies suggest that glucuronidation is the predominant metabolism pathway for elimination of pradigastat in humans and confirmed the role of uridine 5'-diphosphoglucuronosyltransferase (UGT) enzymes, UGT1A1, -1A3, and -2B7. The in vitro studies using atazanavir as a selective inhibitor of UGT1A1 and -1A3 indicated that these enzymes contribute ∼55% toward the overall glucuronidation pathway. Therefore, a clinical study was conducted to assess the potential for drug interaction between pradigastat and probenecid (purported general UGT inhibitor) or atazanavir (selective UGT1A1, -1A3 inhibitor). The study included 2 parallel cohorts, each with 3 sequential treatment periods and 22 healthy subjects per cohort. The 90%CI of the geometric mean ratios for Cmax,ss and AUCτ,ss of pradigastat were within 0.80-1.25 when administered in combination with probenecid. However, the Cmax,ss and AUCτ,ss of pradigastat decreased by 31% (90%CI: 0.62-0.78) and 26% (0.67-0.82), respectively, when administered in combination with atazanavir. This magnitude of decrease in pradigastat steady-state exposure is not considered clinically relevant. Pradigastat was well tolerated by all subjects, either alone or in combination with atazanavir or probenecid. © 2015, The American College of Clinical Pharmacology.

    Approximately 95% of the population suffers at some point in their lifetime from acne vulgaris. Acne is a multifactorial disease of the pilosebaceous unit. This inflammatory skin disorder is most common in adolescents but also affects neonates, prepubescent children, and adults. Topical conventional systems are associated with various side effects. Novel drug delivery systems have been used to reduce the side effect of drugs commonly used in the topical treatment of acne. Topical treatment of acne with active pharmaceutical ingredients (API) makes direct contact with the target site before entering the systemic circulation which reduces the systemic side effect of the parenteral or oral administration of drug. The objective of the present review is to discuss the conventional delivery systems available for acne, their drawbacks, and limitations. The advantages, disadvantages, and outcome of using various carrier-based delivery systems like liposomes, niosomes, solid lipid nanoparticles, and so forth, are explained. This paper emphasizes approaches to overcome the drawbacks and limitations associated with the conventional system and the advances and application that are poised to further enhance the efficacy of topical acne formulations, offering the possibility of simplified dosing regimen that may improve treatment outcomes using novel delivery system.

    Testing oral fluid for drugs of abuse has been studied under many conditions but rarely has been evaluated in large population databases. We evaluated oral fluid tests in a database from a commercial laboratory in the United Kingdom composed of 8679 confirmed positive results. The results originated from 635,000 specimens collected over the period of May 2004 through September 2006. Oral fluid specimens were collected with the Intercept oral fluid collection device, screened by enzyme immunoassay, and confirmed by GC-MS or GC-MS-MS. The database was organized by collection settings (legal/treatment, N = 8198 specimens; and workplace, N = 481 specimens) and by drug groups (without consideration of collection setting). The drug groups were as follows (number of confirmed positives): amphetamines (468); benzodiazepines (892); buprenorphine (276); cannabinoids (725); cocaine (1443); methadone (998); and opiates (5739). The goal of the study was to provide drug/metabolite prevalence data, concentrations, and drugs/metabolite patterns encountered in oral fluid. Comparison of results by collection setting indicated differences in relative frequency, primarily for opiates and cannabinoids. Opiate positives were most frequently observed for specimens collected in legal/treatment settings, whereas cannabinoids were most frequently reported in the workplace. An array of information on drug and metabolite occurrences and concentration arose from evaluation of the data by drug groups. Amphetamine was the predominant drug reported for the Amphetamines Group; approximately 10% were also positive for MDA and/or MDMA; and methamphetamine was rarely reported. Multiple combinations of diazepam, nordiazepam, oxazepam, temazepam, chlordiazepoxide, and lorazepam were reported for the Benzodiazepine Group. Buprenorphine, an opioid treatment drug, was the predominant analyte reported, but low concentrations of norbuprenorphine were frequently reported. THC was the predominant analyte

    This study aims at evaluating the utility of the population pharmacokinetics approach in therapeutic protein drug-drug-interaction (DDI) assessment. Simulations were conducted for 2 representative victim drugs, methotrexate and trastuzumab, using a parallel-group design with and without the interaction drug. The effect of a perpetrator on the exposure of the victim drug is described as the ratio of clearance/apparent clearance of the victim drug given with or without the perpetrator. The power of DDI assessment was calculated as the percentage of runs with 90% confidence interval of the estimated DDI effect within 80% to 125% for the scenarios of no DDI, benchmarked with the noncompartmental approach with intensive sampling. The impact of the number of subjects, the number of sampling points per subject, sampling time error, and model misspecification on the power of DDI determination were evaluated. Results showed that with equal numbers of subjects in each arm, the population pharmacokinetics approach with sparse sampling may need about the same or a higher number of subjects compared to a noncompartmental approach in order to achieve similar power. Increasing the number of subjects, even if only in the study drug alone arm, can increase the power. Sampling or dosing time error had notable impacts on the power for methotrexate but not for trastuzumab. Model misspecification had no notable impacts on the power for trastuzumab. Overall, the population pharmacokinetics approach with sparse sampling built in phase 2/3 studies allows appropriate DDI assessment with adequate study design and analysis and can be considered as an alternative to dedicated DDI studies. © 2017, The American College of Clinical Pharmacology.

    Social media platforms are increasingly seen as a source of data on a wide range of health issues. Twitter is of particular interest for public health surveillance because of its public nature. However, the very public nature of social media platforms such as Twitter may act as a barrier to public health surveillance, as people may be reluctant to publicly disclose information about their health. This is of particular concern in the context of diseases that are associated with a certain degree of stigma, such as HIV/AIDS. The objective of the study is to assess whether adverse effects of HIV drug treatment and associated sentiments can be determined using publicly available data from social media. We describe a combined approach of machine learning and crowdsourced human assessment to identify adverse effects of HIV drug treatment solely on individual reports posted publicly on Twitter. Starting from a large dataset of 40 million tweets collected over three years, we identify a very small subset (1642; 0.004%) of individual reports describing personal experiences with HIV drug treatment. Despite the small size of the extracted final dataset, the summary representation of adverse effects attributed to specific drugs, or drug combinations, accurately captures well-recognized toxicities. In addition, the data allowed us to discriminate across specific drug compounds, to identify preferred drugs over time, and to capture novel events such as the availability of preexposure prophylaxis. The effect of limited data sharing due to the public nature of the data can be partially offset by the large number of people sharing data in the first place, an observation that may play a key role in digital epidemiology in general.

  2. CYP51 is an essential drug target for the treatment of primary amoebic meningoencephalitis (PAM.

    Anjan Debnath

    2017-12-01

    Full Text Available Primary Amoebic Meningoencephalitis (PAM is caused by Naegleria fowleri, a free-living amoeba that occasionally infects humans. While considered "rare" (but likely underreported the high mortality rate and lack of established success in treatment makes PAM a particularly devastating infection. In the absence of economic inducements to invest in development of anti-PAM drugs by the pharmaceutical industry, anti-PAM drug discovery largely relies on drug 'repurposing'-a cost effective strategy to apply known drugs for treatment of rare or neglected diseases. Similar to fungi, N. fowleri has an essential requirement for ergosterol, a building block of plasma and cell membranes. Disruption of sterol biosynthesis by small-molecule inhibitors is a validated interventional strategy against fungal pathogens of medical and agricultural importance. The N. fowleri genome encodes the sterol 14-demethylase (CYP51 target sharing ~35% sequence identity to fungal orthologues.

    Primary Amoebic Meningoencephalitis (PAM) is caused by Naegleria fowleri, a free-living amoeba that occasionally infects humans. While considered “rare” (but likely underreported) the high mortality rate and lack of established success in treatment makes PAM a particularly devastating infection. In the absence of economic inducements to invest in development of anti-PAM drugs by the pharmaceutical industry, anti-PAM drug discovery largely relies on drug ‘repurposing’—a cost effective strategy to apply known drugs for treatment of rare or neglected diseases. Similar to fungi, N. fowleri has an essential requirement for ergosterol, a building block of plasma and cell membranes. Disruption of sterol biosynthesis by small-molecule inhibitors is a validated interventional strategy against fungal pathogens of medical and agricultural importance. The N. fowleri genome encodes the sterol 14-demethylase (CYP51) target sharing ~35% sequence identity to fungal orthologues. The similarity of targets raises the possibility of repurposing anti-mycotic drugs and optimization of their usage for the treatment of PAM. In this work, we (i) systematically assessed the impact of anti-fungal azole drugs, known as conazoles, on sterol biosynthesis and viability of cultured N. fowleri trophozotes, (ii) identified the endogenous CYP51 substrate by mass spectrometry analysis of N. fowleri lipids, and (iii) analyzed the interactions between the recombinant CYP51 target and conazoles by UV-vis spectroscopy and x-ray crystallography. Collectively, the target-based and parasite-based data obtained in these studies validated CYP51 as a potentially ‘druggable’ target in N. fowleri, and conazole drugs as the candidates for assessment in the animal model of PAM.

    Low antituberculosis (TB) drug levels are common, but their clinical significance remains unclear, and methods of measurement are resource intensive. Subjects initiating treatment for sputum smear-positive pulmonary TB were enrolled from Kibong'oto National TB Hospital, Tanzania, and levels of isoniazid, rifampin, ethambutol, and pyrazinamide were measured at the time of typical peak plasma concentration (C(2 h)). To evaluate the significance of the effect of observed drug levels on Mycobacterium tuberculosis growth, a plasma TB drug activity (TDA) assay was developed using the Bactec MGIT system. Time to detection of plasma-cocultured M. tuberculosis versus time to detection of control growth was defined as a TDA ratio. TDA assays were later performed using the subject's own M. tuberculosis isolate and C(2 h) plasma from the Tanzanian cohort and compared to drug levels and clinical outcomes. Sixteen subjects with a mean age of 37.8 years ± 10.7 were enrolled. Fourteen (88%) had C(2 h) rifampin levels and 11 (69%) had isoniazid levels below 90% of the lower limit of the expected range. Plasma spiked with various concentrations of antituberculosis medications found TDA assay results to be unaffected by ethambutol or pyrazinamide. Yet with a range of isoniazid and rifampin concentrations, TDA exhibited a statistically significant correlation with drug level and drug MIC, and a TDA of ~1.0 indicated the presence of multidrug-resistant TB. In Tanzania, low (≤ 2.0) TDA was significantly associated with both lower isoniazid and rifampin C(2 h) levels, and very low (≤ 1.5) TDA corresponded to a trend toward lack of cure. Study of TDA compared to additional clinical outcomes and as a therapeutic management tool is warranted.

  6. Treatment of drug dependence with Brazilian herbal medicines

    Directory of Open Access Journals (Sweden)

    Elisaldo A. Carlini

    Full Text Available The topic "Herbal Medicines in the Treatment of Addictions" in a country must be preceded by answers to four questions: 1. Does the country in question possess a biodiversity rich enough to allow the discovery of useful medicines? 2. Do local people have tradition and culture to look for and use resources from Nature to alleviate and cure diseases, including drug dependence? 3. Is drug dependence (or addiction present in the country in question? 4. Do people of that country recognize and diagnose such problem as a serious one? Alcohol is, by far, the most serious health problem when drug abuse is considered, reaching all of Brazilian society, including the Indians. On the contrary, other drugs may be considered as minor problems and they are not the main focus of this manuscript. The people living in Brazilian hinterland don’t have access to public health systems. Consequently, these people seek assistance from "curandeiros" and "raizeiros"; the Indians are assisted by the shaman. These "folk doctors" do not know the academic medicine and therapeutics, and resort to the local plants to treat different ailments of their patients. Furthermore, alcohol abuse and dependence are not recognized by them, according to the rules and criteria of academic medicine. We have conducted a survey in many Brazilian books, Thesis concerning phytotherapy, and several databank. The results of such searches were very disappointing. No published papers from Brazilian authors concerning the use of plants for the treatment of addictions were found in the databases and there were only three very short notes in the masterly book written by Shultes and Raffauf (1990. From the Brazilian books on folk medicine employing medicinal plants, ten mentions were disclosed: most of them dealing with treatment of alcohol problems and two to counteract "Ayahuasca" dependence.

    Full Text Available Glaucoma is a group of heterogeneous disorders involving progressive optic neuropathy that can culminate into visual impairment and irreversible blindness. Effective therapeutic interventions must address underlying vulnerability of retinal ganglion cells (RGCs to degeneration in conjunction with correcting other associated risk factors (such as elevated intraocular pressure. However, realization of therapeutic outcomes is heavily dependent on suitable delivery system that can overcome myriads of anatomical and physiological barriers to intraocular drug delivery. Development of clinically viable sustained release systems in glaucoma is a widely recognized unmet need. In this regard, implantable delivery systems may relieve the burden of chronic drug administration while potentially ensuring high intraocular drug bioavailability. Presently there are no FDA-approved implantable drug delivery devices for glaucoma even though there are several ongoing clinical studies. The paper critically assessed the prospects of polymeric implantable delivery systems in glaucoma while identifying factors that can dictate (a patient tolerability and acceptance, (b drug stability and drug release profiles, (c therapeutic efficacy, and (d toxicity and biocompatibility. The information gathered could be useful in future research and development efforts on implantable delivery systems in glaucoma.

    Helicobacter pylori is one of the most common pathogenic bacterial infections, colonising an estimated half of all humans. It is associated with the development of serious gastroduodenal disease - including peptic ulcers, gastric lymphoma and acute chronic gastritis. Current recommended regimes are not wholly effective and patient compliance, side-effects and bacterial resistance can be problematic. Drug delivery to the site of residence in the gastric mucosa may improve efficacy of the current and emerging treatments. Gastric retentive delivery systems potentially allow increased penetration of the mucus layer and therefore increased drug concentration at the site of action. Proposed gastric retentive systems for the enhancement of local drug delivery include floating systems, expandable or swellable systems and bioadhesive systems. Generally, problems with these formulations are lack of specificity, limited to mucus turnover or failure to persist in the stomach. Gastric mucoadhesive systems are hailed as a promising technology to address this issue, penetrating the mucus layer and prolonging activity at the mucus-epithelial interface. This review appraises gastroretentive delivery strategies specifically with regard to their application as a delivery system to target Helicobacter. As drug-resistant strains emerge, the development of a vaccine to eradicate and prevent reinfection is an attractive proposition. Proposed prophylactic and therapeutic vaccines have been delivered using a number of mucosal routes using viral and non-viral vectors. The delivery form, inclusion of adjuvants, and delivery regime will influence the immune response generated.

    The incidence of obesity and its associated comorbidities have significantly increased over the years with adverse health and financial consequences for society. Lifestyle changes are essential for the prevention and treatment of obesity but their benefit appears limited as inadequate and nonsustained weight loss results have been reported. Pharmacotherapy is frequently advocated as part of a weight loss strategy. In this review, we will discuss the antiobesity drugs with Food and Drug Administration approval and their cardiovascular implications. Orlistat (Xenical) remains the single monotherapy that has approval in Europe. Topiramate (Topamax) and phentermine have long been approved in the United States, whereas lorcaserin and the extended release combination of phentermine with topiramate have recently gained approval. The development of single peptides targeting gut hormones or other host signals related to obesity may represent promising therapeutic options. Despite the recent failures of a number of antiobesity drugs, the pharmacotherapy of obesity is progressing rapidly. Treating the obese cardiovascular patient has proven challenging. Efficacy, safety and the sustainability of weight loss are key areas of focus in drug development strategies.

    Traditional chemotherapy used today at clinics is mainly inherited from the thinking and designs made four decades ago when the Cancer War was declared. The potency of those chemotherapy drugs on in-vitro cancer cells is clearly demonstrated at even nanomolar levels. However, due to their non-specific effects in the body on normal tissues, these drugs cause toxicity, deteriorate patient's life quality, weaken the host immunosurveillance system, and result in an irreversible damage to human's own recovery power. Owing to their unique physical and biological properties, nanotechnology-based chemotherapies seem to have an ability to specifically and safely reach tumor foci with enhanced efficacy and low toxicity. Herein, we comprehensively examine the current nanotechnology-based pharmaceutical platforms and strategies for intelligent design of new nanomedicines based on targeted drug delivery system (TDDS) for cancer metastasis treatment, analyze the pros and cons of nanomedicines versus traditional chemotherapy, and evaluate the importance that nanomaterials can bring in to significantly improve cancer metastasis treatment.

    2017-07-01

    The widespread implementation of immunosuppressants, immunomodulators, hematopoietic stem cell transplantation and solid organ transplantation in clinical practice has led to an expanding population of patients who are at risk for invasive candidiasis, which is the most common form of fungal disease among hospitalized patients in the developed world. The emergence of drug-resistant Candida spp. has added to the morbidity associated with invasive candidiasis and novel therapeutic strategies are urgently needed. Areas covered: In this paper, we explore investigational agents for the treatment of invasive candidiasis, with particular attention paid to compounds that have recently entered phase I or phase II clinical trials. Expert opinion: The antifungal drug development pipeline has been severely limited due to regulatory hurdles and a systemic lack of investment in novel compounds. However, several promising drug development strategies have recently emerged, including chemical screens involving Pathogen Box compounds, combination antifungal therapy, and repurposing of existing agents that were initially developed to treat other conditions, all of which have the potential to redefine the treatment of invasive candidiasis.

  13. Tumor burden talks in cancer treatment with PEGylated liposomal drugs.

    Full Text Available PURPOSE: PEGylated liposomes are important drug carriers that can passively target tumor by enhanced permeability and retention (EPR effect in neoplasm lesions. This study demonstrated that tumor burden determines the tumor uptake, and also the tumor response, in cancer treatment with PEGylated liposomal drugs in a C26/tk-luc colon carcinoma-bearing mouse model. METHODS: Empty PEGylated liposomes (NanoX and those encapsulated with VNB (NanoVNB were labeled with In-111 to obtain InNanoX and InVNBL in high labeling yield and radiochemical purity (all >90%. BALB/c mice bearing either small (58.4±8.0 mm(3 or large (102.4±22.0 mm(3 C26/tk-luc tumors in the right dorsal flank were intravenously administered with NanoVNB, InNanoX, InVNBL, or NanoX as a control, every 7 days for 3 times. The therapeutic efficacy was evaluated by body weight loss, tumor growth inhibition (using calipers and bioluminescence imaging and survival fraction. The scintigraphic imaging of tumor mouse was performed during and after treatment. RESULTS: The biodistribution study of InVNBL revealed a clear inverse correlation (r (2 = 0.9336 between the tumor uptake and the tumor mass ranged from 27.6 to 623.9 mg. All three liposomal drugs showed better therapeutic efficacy in small-tumor mice than in large-tumor mice. Tumor-bearing mice treated with InVNBL (a combination drug showed the highest tumor growth inhibition rate and survival fraction compared to those treated with NanoVNB (chemodrug only and InNanoX (radionuclide only. Specific tumor targeting and significantly increased tumor uptake after periodical treatment with InVNBL were evidenced by scintigraphic imaging, especially in mice bearing small tumors. CONCLUSION: The significant differences in the outcomes of cancer treatment and molecular imaging between animals bearing small and large tumors revealed that tumor burden is a critical and discriminative factor in cancer therapy using PEGylated liposomal drugs.

    Full Text Available Abstract Background Throughout Africa, the private retail sector has been recognised as an important source of antimalarial treatment, complementing formal health services. However, the quality of advice and treatment at private outlets is a widespread concern, especially with the introduction of artemisinin-based combination therapies (ACTs. As a result, ACTs are often deployed exclusively through public health facilities, potentially leading to poorer access among parts of the population. This research aimed at assessing the performance of the retail sector in rural Tanzania. Such information is urgently required to improve and broaden delivery channels for life-saving drugs. Methods During a comprehensive shop census in the districts of Kilombero and Ulanga, Tanzania, we interviewed 489 shopkeepers about their knowledge of malaria and malaria treatment. A complementary mystery shoppers study was conducted in 118 retail outlets in order to assess the vendors' drug selling practices. Both studies included drug stores as well as general shops. Results Shopkeepers in drug stores were able to name more malaria symptoms and were more knowledgeable about malaria treatment than their peers in general shops. In drug stores, 52% mentioned the correct child-dosage of sulphadoxine-pyrimethamine (SP compared to only 3% in general shops. In drug stores, mystery shoppers were more likely to receive an appropriate treatment (OR = 9.6, but at an approximately seven times higher price. Overall, adults were more often sold an antimalarial than children (OR = 11.3. On the other hand, general shopkeepers were often ready to refer especially children to a higher level if they felt unable to manage the case. Conclusion The quality of malaria case-management in the retail sector is not satisfactory. Drug stores should be supported and empowered to provide correct malaria-treatment with drugs they are allowed to dispense. At the same time, the role of general shops

    Autoimmune pancreatitis is one of the few diseases of the pancreas characterized by the possibility of curing the illness using immunosuppressant drugs. In this paper, the therapeutic approach used to treat autoimmune pancreatitis patients and the clinical outcome related to each treatment modality were reviewed. Steroids are useful in alleviating the symptoms of the acute presentation of autoimmune pancreatitis, but some questions remain open, such as a shared definition of the disease's remission as well as autoimmune pancreatitis relapse, the dosage of steroids in the symptomatic phase of the disease and the duration of steroid therapy. Finally, it should be determined if other immunosuppressive nonsteroidal drugs could become first-line therapy in patients with autoimmune pancreatitis without jaundice and without atrophic pancreas.

    This study examined the predictors of self-reported health status at follow-up in the Drug Abuse Treatment Outcomes Study (DATOS), a longitudinal study of drug abuse treatment programs and patients in 1991-1993. Baseline and follow-up interviews of 2966 patients in 75 programs were performed. The follow-up assessment was targeted to occur 12 months after treatment terminated; long-term methadone patients in treatment for the entire 12-month period were interviewed 24 months after intake. A composite measure, developed through principal component analysis, assessed health status. A multivariate hierarchical linear regression model adjusted for identified independent baseline predictors of health status at follow-up. Poor physical health status (including the composite measure, comorbid conditions and pain) and greater severity of psychiatric symptoms at baseline were the strongest predictors of poor health status at follow-up. Other predictors of worse health status included older age, public insurance coverage and unemployment. We conclude that baseline health status and psychiatric symptoms predict the subsequent health status of patients in substance abuse treatment patients as in other clinical populations. Future research should examine whether early identification and treatment of physical and mental health problems among patients in addiction treatment programs might remediate their adverse effects on long-term health status outcomes.

  17. Neuraxial drug administration: a review of treatment options for anaesthesia and analgesia.

    2006-01-01

    Neuraxial drug administration describes techniques that deliver drugs in close proximity to the spinal cord, i.e. intrathecally into the CSF or epidurally into the fatty tissues surrounding the dura, by injection or infusion. This approach was initially developed in the form of spinal anaesthesia over 100 years ago. Since then, neuraxial drug administration has evolved and now includes a wide range of techniques to administer a large number of different drugs to provide anaesthesia, but also analgesia and treatment of spasticity in a variety of acute and chronic settings. This review concentrates on the pharmacological agents used and the clinical basis behind currently utilised approaches to neuraxial drug administration. With regard to local anaesthetics, the main focus is on the development of the enantiomer-specific compounds ropivacaine and levobupivacaine, which provide similar efficacy to bupivacaine with a reduced risk of severe cardiotoxicity. Opioids are the other group of drugs widely used neuraxially, in particular to provide analgesia alone or more commonly in combination with other agents. The physicochemical properties of the various opioids explain the main differences in efficacy and safety between these drugs when used intrathecally, of which morphine, fentanyl and sufentanil are most commonly used. Another group of drugs including clonidine, dexmedetomidine and epinephrine (adrenaline) provide neuraxial analgesia via alpha-adrenergic receptors and are used mainly as adjuvants to local anaesthetics and opioids. Furthermore, intrathecal baclofen is in routine clinical use to treat spasticity in a number of neurological conditions. Beside these established approaches, a wide range of other drugs have been assessed for neuraxial administration to provide analgesia; however, most are in various early stages of investigation and are not used routinely. These drugs include neostigmine, ketamine, midazolam and adenosine, and the conotoxin ziconotide. The

    2014-08-01

    Ample evidence that nitric oxide (NO) is a causative molecule in migraine has encouraged research to develop drugs that target the NO-cGMP cascade for migraine treatment. NO synthase (NOS) inhibition is an innovative therapeutic principle. This paper reviews the rationale underlying NOS inhibition in migraine treatment. It also provides a review on the efficacy and safety data for NOS inhibitors (nonselective NOS inhibitor L-N(G)-methyl-arginine hydrochloride [L-NMMA], selective inducible NOS [iNOS] inhibitors GW273629 and GW274150, combined neuronal NOS [nNOS] inhibitor and 5-HT1B/1D receptor agonist NXN-188) in acute or preventive migraine treatment. The data highlighted herein, from four placebo-controlled trials and 1 open-labeled clinical trial using 4 different NOS inhibitors on a total of 705 patients, provide convincing efficacy data only for the nonselective NOS inhibitor L-NMMA. Unfortunately, this NOS inhibitor raises cardiovascular safety concerns and has an unfavorable pharmacokinetic profile. As experimental studies predicted, iNOS inhibitors are ineffective in migraine. Still, upcoming selective nNOS inhibitors are a hope for migraine treatment, with the nNOS isoform being most clearly involved in trigeminovascular transmission and central sensitization. Future studies should help to clarify whether NOS inhibition is equally fruitful in acute and preventive treatment. It should also clarify if nNOS inhibition holds promise as a therapeutic tool for the treatment of chronic migraine and other forms of headache.

  19. Alcohol use by drug addicts during the treatment and follow-up

    Full Text Available This study is about the use of alcohol and its influence during the recuperation of drug addict patients undergoing treatment. Levels of the use of illegal drugs and alcohol were compared before, during and after the treatment of 82 patients assessed over a one-and-a-half year follow-up study. The results show that after the intervention there is an increase of alcohol use by 50% of the addicts. The 10-13% exhibit excessive levels. The higher alcohol use coincide withthe end of the treatment. This tendency changes later (18 months into similar levels as the initialones. These results do not allow to consider the aforementioned increase as a confirmationof the substitution hypothesis, that is the alcohol use-redirection towards other more socially tolerated substances.

    This study describes the validation process for the Slovenian version of the Drug Addiction Treatment Efficacy Questionnaire (DATEQ). DATEQ was constructed from the questionnaires used at the Centre for the Treatment of Drug Addiction, Ljubljana University Psychiatric Hospital, and within the network of Centres for the Prevention and Treatment of Drug Addiction in Slovenia during the past 14 years. The Slovenian version of the DATEQ was translated to English using the 'forward-backward' procedure by its authors and their co-workers. The validation process included 100 male and female patients with established addiction to illicit drugs who had been prescribed opioid substitution therapy. The DATEQ questionnaire was used in the study, together with clinical evaluation to measure psychological state and to evaluate the efficacy of treatment in the last year. To determinate the validity of DATEQ the correlation with the clinical assessments of the outcome was calculated using one-way ANOVA. The F value was 44.4, p<0.001 (sum of squares: between groups 210.4, df=2, within groups 229.7, df=97, total 440.1, df=99). At the cut-off 4 the sensitivity is 81% and specificity 83%. The validation process for the Slovenian DATEQ version shows metric properties similar to those found in international studies of similar questionnaires, suggesting that it measures the same constructs, in the same way and as similar questionnaires. However, the relatively low sensitivity and specificity suggests caution when using DATEQ as the only measure of outcome.

    Modification of lifestyle is the main therapeutical approach in the treatment of obesity, but use to fail on long terms of time. Addition of anti-obesity drugs allows keeping the weight loss during years and improving obesity-related comorbidities. This review is an actualisation on efficacy, safety and tolerability of the approved drugs on the long-term treatment of obesity (orlistat and sibutramine). New indications and effects of their use far beyond the weight loss are as well commented. Finally, potential benefits of the administration of CB1 antagonist rimonabant on the weight loss and cardiometabolic risk factors are analysed in detail. A decade of experience on the use of orlistat and sibutramine has demonstrated their higher efficacy on the weight loss when compared to placebo either on adult or teenage population as well as safety and tolerability on long-term administration. Beneficial effects on the lipid profile, glycosilated haemoglobin on diabetic patients, blood pressure and levels of inflammatory cytokines, contribute to decrease the cardiovascular risk on obese patients. Phase III clinical trials using rimonabant show additional benefits to the expected weight loss, mainly reducing visceral fat and cardiometabolic risk factors. Pharmacological treatment of obesity must be considered as a therapeutical tool that has to be used together with long-term lifestyle changes, contributing to the body weight reduction as well as to the improvement of the cardiometabolic risk related to obesity.

    2016-06-01

    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

    2013-11-01

    Narcolepsy/hypocretin deficiency (now called type 1 narcolepsy) is a lifelong neurologic disorder with well-established diagnostic criteria and etiology. Narcolepsy is a chronic sleep disorder characterized by excessive daytime sleepiness (EDS) and symptoms of dissociated rapid eye movement sleep such as cataplexy (sudden loss of muscle tone), hypnagogic hallucinations (sensory events that occur at the transition from wakefulness to sleep), sleep paralysis (inability to perform movements upon wakening or sleep onset), and nocturnal sleep disruption. As these symptoms are often disabling, most patients need life-long treatment. The treatment of narcolepsy is well defined, and, traditionally, amphetamine-like stimulants (i.e., dopaminergic release enhancers) have been used for clinical management to improve EDS and sleep attacks, whereas tricyclic antidepressants have been used as anticataplectics. However, treatments have evolved to better-tolerated compounds such as modafinil or armodafinil (for EDS) and adrenergic/serotonergic selective reuptake inhibitors (as anticataplectics). In addition, night-time administration of a short-acting sedative, c-hydroxybutyrate (sodium oxybate), has been used for the treatment for EDS and cataplexy. These therapies are almost always needed in combination with non-pharmacologic treatments (i.e., behavioral modification). A series of new drugs is currently being tested in animal models and in humans. These include a wide variety of hypocretin agonists, melanin- concentrating hormone receptor antagonists, antigenspecific immunopharmacology, and histamine H3 receptor antagonists/inverse agonists (e.g., pitolisant), which have been proposed for specific therapeutic applications, including the treatment of Alzheimer's disease, attention-deficit hyperactivity disorder, epilepsy, and more recently, narcolepsy. Even though current treatment is strictly symptomatic, based on the present state of knowledge of the pathophysiology of

    2011-01-01

    The neurotransmitter dopamine plays important roles in modulating cognitive, affective, and motor functions. Dysregulation of dopaminergic neurotransmission is thought to be involved in the pathophysiology of several psychiatric and neurological disorders, including schizophrenia, Parkinson’s disease and drug abuse. Dopaminergic systems are regulated by cholinergic, especially muscarinic, input. Not surprisingly, increasing evidence implicates muscarinic acetylcholine receptor-mediated pathways as potential targets for the treatment of these disorders classically viewed as “dopamine based”. There are five known muscarinic receptor subtypes (M1 to M5). Due to their overlapping expression patterns and the lack of receptor subtype-specific ligands, the roles of the individual muscarinic receptors have long remained elusive. During the past decade, studies with knockout mice lacking specific muscarinic receptor subtypes have greatly advanced our knowledge of the physiological roles of the M1–M5 receptors. Recently, new ligands have been developed that can interact with allosteric sites on different muscarinic receptor subtypes, rather than the conventional (orthosteric) acetylcholine binding site. Such agents may lead to the development of novel classes of drugs useful for the treatment of psychosis, drug abuse, and Parkinson’s disease. The present review highlights recent studies carried out using muscarinic receptor knockout mice and new subtype-selective allosteric ligands to assess the roles of M1, M4, and M5 receptors in various central processes that are under strong dopaminergic control. The outcome of these studies opens new perspectives for the use of novel muscarinic drugs for several severe disorders of the central nervous system. PMID:22389751

    Gout patients receiving a combination of allopurinol and furosemide require higher allopurinol doses to achieve the target serum urate (SU) of furosemide and oxypurinol (the active metabolite of allopurinol) on xanthine oxidase (XO) activity. Immunoblot analysis quantified expression of XO and AMP-kinase (AMPK) in drug-treated human liver (HepG2) and primary kidney (HRCE) cells. In silico analysis identified miR-448 as a potential XO-regulator, whose expression level in HepG2 cells was examined by qPCR. Fluorimetric experiments revealed no direct interactions between XO and furosemide, nor did the combination of oxypurinol/furosemide alter the XO inhibition profile of oxypurinol. In HepG2 cells, we found a significant decrease in XO protein expression following oxypurinol treatment, which was abolished after co-incubation with furosemide. Probenecid alone or in combination with furosemide reduced XO protein expression significantly. qPCR analysis of miR-448 in HepG2 cells mirrored the drug-dependent changes in XO protein expression. In addition, oxypurinol and the combination of oxypurinol/furosemide significantly down-regulated AMPK protein expression in HRCE cells. In conclusion, we show for the first time that besides the established effects of allopurinol on the purine synthetic pathway the efficiency of allopurinol treatment of gout patients is based on two further complementary mechanisms, the direct inhibition of XO activity by the allopurinol metabolite oxypurinol and a down-regulation of XO protein expression. The latter is compromised by addition of furosemide and might explain why patients receiving furosemide therapy require higher allopurinol doses. miR-448 was identified as a potential drug-dependent XO regulator. Finally, down-regulation of AMPK protein expression in HRCE cells by administration of oxypurinol/furosemide reveals a possible new mechanism of renal drug-induced hyperuricemia.

    Several methodological reviews of alcohol treatment outcome studies and one review of drug studies have been published over the past 40 years. Although past reviews demonstrated methodological improvements in alcohol studies, they also found continued deficiencies. The current review allows for an updated evaluation of the methodological rigor of alcohol and drug studies and, by utilizing inclusion criteria similar to previous reviews, it allows for a comparative review over time. In addition, this is the first review that compares the methodology of alcohol and drug treatment outcome studies published during the same time period. The methodology for 25 alcohol and 11 drug treatment outcome studies published from 2005 through 2010 that met the review's inclusion criteria was evaluated. The majority of variables evaluated were used in prior reviews. The current review found that more alcohol and drug treatment outcome studies are now using continuous substance use measures and assessing problem severity. Although there have been methodological improvements over time, the current reviews differed little from their most recent past counterpart. Despite this finding, some areas, particularly the continued low reporting of demographic data, needs strengthening. Improvement in the methodological rigor of alcohol and drug treatment outcome studies has occurred over time. The current review found few differences between alcohol and drug study methodologies as well as few differences between the current review and the most recent past alcohol and drug reviews. © 2013 Elsevier Ltd.

    unnecessary bureaucracy and regulation. As a student of Tom's in the 1970s in London, working on hepatoma-specific alkylating agents at Charing Cross Hospital in collaboration with his lab on the other side of town, I can attest to the fact that the regulatory hurdles to cancer drug development just twenty years later have added immeasurably to the effort and cost of cancer drug development. However, I look with optimism to the future of cancer diagnosis, prevention and treatment. It is a future where what we are learning now about the molecular and genetic basis of cancer will find their clinical outlet just as surely as the anatomic, microbial, metabolic and endocrine basis for disease has in the past. This new knowledge will provide new techniques in molecular diagnosis, which will allow us to predict which in situ cancers are destined for malignant behavior, and which can be safely watched without the need for intervention. Individual patient risk for particular cancers will be accurately predictable, so that patients can alter lifestyle habits or begin other prevention strategies. Oncogenes and growth suppressor genes give us new targets to inhibit or replace. Tumor-specific kinases will meet their inhibitors. The oncologist will play a leading role in understanding, applying and interpreting this new information in the clinic-an exciting and challenging future!

  8. Toxicity Evaluation of Through Fish Bioassay Raw Bulk Drug Industry Wastewater After Electrochemical Treatment

    Full Text Available Considering the high pollution potential that the synthetic Bulk Drug industry Wastewater (BDW possesses due to the presence of variety of refractory organics, toxicity evaluation is of prime importance in assessing the efficiency of the applied wastewater treatment system and in establishing the discharge standards. Therefore, in this study the toxic effects of high strength bulk drug industry wastewater before and after electrochemical treatment on common fish Lebistes reticulatus-(peter were studied under laboratory conditions. Results indicated that wastewater being very strong in terms of color, COD and BOD is found to be very toxic to the studied fish. The LC50 values for raw wastewater and after electrochemical treatment with carbon and aluminium electrodes for 24, 48, 72 and 96 hours ranged between, 2.5-3.6%, 6.8-8.0%, 5.0-5.8% respectively. Carbon electrode showed marginally better removals for toxicity than aluminium electrode. It was evident from the studies that electrochemical treatment reduces toxicity in proportion to the removal efficiency shown by both the electrodes. The reduction in toxicity after treatment indicates the intermediates generated are not toxic than the parent compounds. Furthermore, as the electrochemical treatment did not result in achieving disposal standards it could be used only as a pre-treatment and the wastewater needs further secondary treatment before final disposal.

    This study examined factors associated with treatment drop-out among young people aged 13-19 years attending alcohol and other drug (AOD) treatment. Data were gathered from structured interviews (n = 79) and a clinical file search of 184 randomly selected young people who had attended youth specific AOD treatment services in Aotearoa, New Zealand during 2003 or 2004. The median length of stay was 2.7 months for those attending day/residential services (n = 42) and 4.0 sessions for those attending outpatient services (n = 37) 16.7% of participants from day/residential services dropped out of treatment early (within the first month) and 32.4% of participants from outpatient treatment services dropped out of treatment early (before the third session). Fixed client characteristics, such as age, sex, ethnicity, substance use and mental health diagnoses were not found to be associated with treatment retention. Dynamic client characteristics, such as motivation to attend treatment and expectations about treatment outcomes and program characteristics, such as positive experiences with treatment staff and feeling involved in the treatment process were found to be associated with treatment retention. The findings of this study support previous research indicating that fixed client characteristics are not sufficient to explain youth retention in AOD treatment. Of more use are dynamic client characteristics and program variables. These findings stress the potential for improving treatment retention by creating more youth appropriate services.

    This study explored the prevalence of violent and/or criminal behaviors in drug-addicted patients. A sample of 252 drug-addicted patients who sought treatment was assessed. Information was collected on violent behaviors, criminal acts, socio-demographic factors, consumption factors, psychopathological factors, and personality variables. The sample was divided into 4 groups according to the presence of violence and/or criminal behaviors. There were significant differences between the groups on some variables. In general, patients associated with both violence and criminal behaviors showed a greater severity in drug consumption and maladjustment variables, as well as a higher rate of treatment dropout and re-entry.

    A lifetime injection drug history is necessary to examine the impact of injection drug use on a physical health problem but it may cover time periods for which information and/or data reported may not be reliable. A test-retest study design was used to examine a technique of questioning persons about lifetime illicit injection drug use history (the Lifetime Injection History Questionnaire), including its reliability and relation to chronic venous disorders as an assessment of validity. Study participants included 104 persons (60 men, 44 women, M age = 49.3 years) provided services at a methadone maintenance treatment center located in a large industrial city in the Midwest. Kappa values for "ever injected" drugs ranged from 1.00 for heroin to .50 for nonprescription methadone (median = .75). High interclass correlations were found for youngest and oldest ages of injecting, years not injecting, and total injecting years (.90 to .98). Interclass correlation values for years injecting in the upper body and lower body were .79 and .70, respectively. Interrater reliability for the clinical portion of the venous disease assessment tool (the Clinical-Etiology-Anatomy-Pathophysiology - CEAP - classification) was high: .97, right leg; .94, left leg. Controlling for age, gender, comorbidities, and body mass index, a classification of injection drug use based on the Lifetime Injection History scales accounted for 32% of the variance in the clinical CEAP scores. This is the first study to examine years of injection drug use that takes periods not injecting drugs into consideration. Focused substance abuse questioning (eg, drug, route, years of use) may help clinicians evaluate health problems related to drug use.

    2013-01-01

    Mood disorders are common and debilitating, resulting in a significant public health burden. Current treatments are only partly effective and patients who have failed to respond to trials of existing antidepressant agents (eg, those who suffer from treatment-resistant depression [TRD]) require innovative therapeutics with novel mechanisms of action. Although neuroscience research has elucidated important aspects of the basic mechanisms of antidepressant action, most antidepressant drugs target monoaminergic mechanisms identified decades ago. Glutamate, the major excitatory neurotransmitter in the central nervous system, and glutamatergic dysfunction has been implicated in mood disorders. These data provide a rationale for the pursuit of glutamatergic agents as novel therapeutic agents. Here, we review preclinical and clinical investigations of glutamatergic agents in mood disorders with a focus on depression. We begin with discussion of evidence for the rapid antidepressant effects of ketamine, followed by studies of the antidepressant efficacy of the currently marketed drugs riluzole and lamotrigine. Promising novel agents currently in development, including N-methyl-D-aspartate (NMDA) receptor modulators, 2-amino-3-(3-hydroxy-5-methyl-isoxazol-4-yl) propanoic acid (AMPA) receptor modulators, and drugs with activity at the metabotropic glutamate (mGlu) receptors are then reviewed. Taken together, both preclinical and clinical evidence exists to support the pursuit of small molecule modulators of the glutamate system as novel therapeutic agents in mood disorders. It is hoped that by targeting neural systems outside of the monoamine system, more effective and perhaps faster acting therapeutics can be developed for patients suffering from these disabling disorders.

    2017-09-10

    The advancements in electronics and the progress in nanotechnology have resulted in path breaking development that will transform the way diagnosis and treatment are carried out currently. This development is Medical Capsule Robots, which has emerged from the science fiction idea of robots travelling inside the body to diagnose and cure disorders. The first marketed capsule robot was a capsule endoscope developed to capture images of the gastrointestinal tract. Today, varieties of capsule endoscopes are available in the market. They are slightly larger than regular oral capsules, made up of a biocompatible case and have electronic circuitry and mechanisms to capture and transmit images. In addition, robots with diagnostic features such as in vivo body temperature detection and pH monitoring have also been launched in the market. However, a multi-functional unit that will diagnose and cure diseases inside the body has not yet been realized. A remote controlled capsule that will undertake drug delivery and surgical treatment has not been successfully launched in the market. High cost, inadequate power supply, lack of control over drug release, limited space for drug storage on the capsule, inadequate safety and no mechanisms for active locomotion and anchoring have prevented their entry in the market. The capsule robots can revolutionize the current way of diagnosis and treatment. This paper discusses in detail the applications of medical capsule robots in diagnostics, drug delivery and surgical treatment. In diagnostics, detailed analysis has been presented on wireless capsule endoscopes, issues associated with the marketed versions and their corresponding solutions in literature. Moreover, an assessment has been made of the existing state of remote controlled capsules for targeted drug delivery and surgical treatment and their future impact is predicted. Besides the need for multi-functional capsule robots and the areas for further research have also been

    Full Text Available Drug resistance mutations archived in resting memory CD4+ cells may persist despite suppression of HIV RNA to <50 copies/ml. We sequenced pol gene from proviral DNA among viremic and suppressed patients to identify drug resistance mutations.The Peninsula AIDS Research Cohort study enrolled and followed over 2 years 120 HIV infected patients from San Mateo and San Francisco Counties. HIV-1 pol genotyping by bulk sequencing was performed on 38 DNA and RNA from viremic patients and DNA only among 82 suppressed patients at baseline. Antiretroviral susceptibility was predicted by HIVDB.stanford.edu.Among 120 subjects, 81% were on antiretroviral therapy and had been treated for a median time of 7 years. Thirty-two viremic patients showed concordant RNA and DNA genotypes (84%; the discordant profiles were mainly observed in patients with low-level viremia. Among suppressed patients, 21 had drug resistance mutations in proviral DNA (26% with potential resistance to one, two or three ARV classes in 16, 4 and 1 samples respectively.The high level of genotype concordance between DNA and RNA in viremic patients suggested that DNA genotyping might be used to assess drug resistance in resource-limited settings, and further investigation of extracted DNA from dried blood spots is needed. Drug resistance mutations in proviral DNA in 26% of subjects with less than 50 copies/ml pose a risk for the transmission of drug resistant virus with virologic failure, treatment interruption or decreased adherence.

    Hepatitis C virus (HCV) infection is common among people who inject drugs, including those managed with maintenance opioids. Pharmacokinetic interactions between opioids and emerging oral HCV antivirals merit evaluation. Daclatasvir is a potent pangenotypic inhibitor of the HCV NS5A replication complex recently approved for HCV treatment in Europe and Japan in combination with other antivirals. The effect of steady-state daclatasvir (60 mg daily) on stable plasma exposure to oral opioids was assessed in non-HCV-infected subjects receiving methadone (40 to 120 mg; n = 14) or buprenorphine plus naloxone (8 to 24 mg plus 2 to 6 mg; n = 11). No relevant interaction was inferred if the 90% confidence interval (CI) of the geometric mean ratio (GMR) of opioid area under the plasma concentration-time curve over the dosing interval (AUCτ) or maximum concentration in plasma (C max) with versus without daclatasvir was within literature-derived ranges of 0.7 to 1.43 (R- and S-methadone) or 0.5 to 2.0 (buprenorphine and norbuprenorphine). Dose-normalized AUCτ for R-methadone (GMR, 1.08; 90% CI, 0.94 to 1.24), S-methadone (1.13; 0.99 to 1.30), and buprenorphine (GMR, 1.37; 90% CI, 1.24 to 1.52) were within the no-effect range. The norbuprenorphine AUCτ was slightly elevated in the primary analysis (GMR, 1.62; 90% CI, 1.30 to 2.02) but within the no-effect range in a supplementary analysis of all evaluable subjects. Dose-normalized C max for both methadone enantiomers, buprenorphine and norbuprenorphine, were within the no-effect range. Standardized assessments of opioid pharmacodynamics were unchanged throughout daclatasvir administration with methadone or buprenorphine. Daclatasvir pharmacokinetics were similar to historical data. Coadministration of daclatasvir and opioids was generally well tolerated. In conclusion, these data suggest that daclatasvir can be administered with buprenorphine or methadone without dose adjustments. Copyright © 2015, American Society for

    Drug addiction can be a devastating and chronic relapsing disorder with social, psychological, and physical consequences, and more effective treatment options are needed. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive brain stimulation technique that has been assessed in a growing number of studies for its therapeutic potential in treating addiction. This review paper offers an overview on the current state of clinical research in treating drug addiction with rTMS. Because of the limited research in this area, all studies (including case reports) that evaluated the therapeutic use of rTMS in nicotine, alcohol, or illicit drug addiction were included in this review. Papers published prior to December 2012 were found through an NCBI PubMed search. A total of eleven studies were identified that met review criteria. There is nascent evidence that rTMS could be effective in reducing cocaine craving and nicotine and alcohol craving and consumption and might represent a potential therapeutic tool for treating addiction. Further studies are needed to identify the optimal parameters of stimulation for the most effective treatment of drug addiction, to improve our comprehension of the treatment neurophysiological effects, and to conduct rigorous, controlled efficacy studies with adequate power.

    The safety and tolerability of short-term treatment with a low dose of risperidone was evaluated in adolescents with prodromal symptoms and a family history of schizophrenia. Four prodromal high-risk adolescents and six first-episode patients with schizophrenia were treated with average doses of 1.0 and 1.8 mg/day of risperidone, respectively, in an 8- to 12-week open-label trial. No significant treatment-related adverse events were noted. Severity of thought and behavior disturbance ratings declined by about 30%; performance on a test of verbal learning improved by about 100% during treatment in both prodromal and first-episode patients, changes that achieved statistical significance despite the small group sizes. These findings are preliminary and should not be used to guide health care decisions at this time. Randomized controlled trials are needed to determine whether antipsychotic drug treatment of prodromal patients can delay or prevent onset or attenuate the clinical course of schizophrenia.

    Recovery among adolescents undergoing substance abuse treatment was modeled in terms of pre-treatment motivation, therapeutic relationships, psychological functioning, treatment retention, legal pressures, DSM diagnoses, and client demographics. To address between program differences, a within-covariance matrix, based on 547 youth, was used. Applicability of the results across treatment modalities was also examined. The data were from the NIDA-sponsored DATOS Adolescent study. Results from structural equation models (estimated using Mplus) indicated that higher pre-treatment motivation predicted stronger counselor and in-treatment peer relationships, better counselor relationships and retention predicted less illegal drug use at follow-up, and DSM diagnosis was important in the treatment process. Overall, illegal drug use at follow-up was associated with post-treatment alcohol consumption, cigarette use, condom nonuse, psychological distress, criminality, and school non-attendance. The results document the importance of motivation and therapeutic relationships on recovery, even when taking into account the relative effects of legal pressures, DSM diagnoses, and demographics.

    In August 2009, Mexico reformed its drug laws and decriminalized small quantities of drugs for personal use; offenders caught three times will be mandated to enter drug treatment. However, little is known about the quality or effectiveness of drug treatment programs in Mexico. We examined injection drug users' (IDUs) experiences in drug treatment in Tijuana, Mexico, with the goal of informing program planning and policy. We examined qualitative and quantitative data from Proyecto El Cuete, a multi-phased research study on HIV risk among IDUs in Tijuana. Phase I consisted of 20 in-depth interviews and Phase II employed respondent-driven sampling to recruit 222 IDUs for a quantitative survey. We also reviewed national drug policy documents, surveillance data, and media reports to situate drug users' experiences within the broader sociopolitical context. Participants in the qualitative study were 50% male with a mean age of 32; most injected heroin (85.0%) and methamphetamine (60.0%). The quantitative sample was 91.4% male with a mean age of 35; 98.2% injected heroin and 83.7% injected heroin and methamphetamine together. The majority of participants reported receiving treatment: residential treatment was most common, followed by methadone; other types of services were infrequently reported. Participants' perceptions of program acceptability and effectiveness were mixed. Mistreatment emerged as a theme in the qualitative interviews and was reported by 21.6% of Phase II participants, primarily physical (72.0%) and verbal (52.0%) abuse. Our results point to the need for political, economic, and social investment in the drug treatment system before offenders are sentenced to treatment under the revised national drug law. Resources are needed to strengthen program quality and ensure accountability. The public health impact of the new legislation that attempts to bring drug treatment to the forefront of national drug policy should be systematically evaluated. Copyright

    Toxicologists must ensure that clinical risk-to-benefit analysis should be made both for genders and age groups, with any treatment. Puberty concerns physiological changes leading to organism's maturation. Pubertal growth disorders are increasing in last decades: besides causing physical and psychological distress, they may signal underlying endocrine-metabolic abnormalities with serious health consequences later on. Therapeutic approaches for some health conditions in childhood and adolescence are considered. The authors discuss how some diseases and treatments can impact pubertal growth. The authors look at particular immunological disorders such as asthma and how both the disease and treatment affects pubertal growth. They also discuss how the provision of available data can help to assess the dose-response of the drug, in these cases, and minimize the chance of side effects. The authors also discuss pediatric inflammatory bowel disease and how both the disease and treatment can mitigate the growth delay. Last, but not least, the authors discuss how the effects of the drugs used in the treatment of psychiatric disorders may accentuate endocrine issues in juvenile patients. Hyperprolactinemia induction by some antipsychotics is highlighted as an example. Appropriate risk-benefit analysis of drugs prescribed during childhood and adolescence and intended to be used in the long term is required. Furthermore, future treatment strategies and safer compounds development should be supported by the knowledge of mechanisms underlying adverse side effects in pubertal growth and development.

    To document the prospective, reciprocal relationships among substance use problems, utilization of drug treatment, and predisposing beliefs thought to increase treatment utilization. Persistent Effects of Treatment Study-Adolescent (PETS-A), conducted by the Center on Substance Abuse Treatment. This was a longitudinal study of youths originally participating in one of two CSAT studies; one sample included 476 youths receiving residential drug treatment, and the other included 519 youths receiving outpatient treatment. This study uses five waves of data collected over a 12-month period to examine the temporal relationships among four variables: treatment dose, substance use problems, drug resistance self-efficacy, and perceived need for treatment (PNT). Data from this longitudinal study were analyzed using cross-lagged panel models, and structural equation modeling techniques were used to estimate the prospective, reciprocal relationships among these four variables in each of the two samples, while controlling for several covariates. Both PNT and low drug resistance self-efficacy led to higher levels of subsequent treatment. However, low self-efficacy presaged increases in drug problems while PNT predicted decreases. Understanding the role of psychological variables in the utilization of health services is complicated for psychological disorders because beliefs that affect treatment can also influence the disorder itself. Efforts to keep adolescents in drug treatment should focus on convincing youth that treatment can help them with their problems, rather than convincing them that they cannot resist drugs on their own. While both messages increase treatment utilization, the latter belief undermines the effects of treatment.

  5. Micropharmacology: An In Silico Approach for Assessing Drug Efficacy Within a Tumor Tissue.

    Karolak, Aleksandra; Rejniak, Katarzyna A

    2018-02-08

    Systemic chemotherapy is one of the main anticancer treatments used for most kinds of clinically diagnosed tumors. However, the efficacy of these drugs can be hampered by the physical attributes of the tumor tissue, such as tortuous vasculature, dense and fibrous extracellular matrix, irregular cellular architecture, tumor metabolic gradients, and non-uniform expression of the cell membrane receptors. This can impede the transport of therapeutic agents to tumor cells in sufficient quantities. In addition, tumor microenvironments undergo dynamic spatio-temporal changes during tumor progression and treatment, which can also obstruct drug efficacy. To examine ways to improve drug delivery on a cell-to-tissue scale (single-cell pharmacology), we developed the microscale pharmacokinetics/pharmacodynamics (microPKPD) modeling framework. Our model is modular and can be adjusted to include only the mathematical equations that are crucial for a biological problem under consideration. This modularity makes the model applicable to a broad range of pharmacological cases. As an illustration, we present two specific applications of the microPKPD methodology that help to identify optimal drug properties. The hypoxia-activated drugs example uses continuous drug concentrations, diffusive-advective transport through the tumor interstitium, and passive transmembrane drug uptake. The targeted therapy example represents drug molecules as discrete particles that move by diffusion and actively bind to cell receptors. The proposed modeling approach takes into account the explicit tumor tissue morphology, its metabolic landscape and/or specific receptor distribution. All these tumor attributes can be assessed from patients' diagnostic biopsies; thus, the proposed methodology can be developed into a tool suitable for personalized medicine, such as neoadjuvant chemotherapy.

    2016-01-01

    Intrathecal drug delivery systems can be used to manage refractory or persistent chronic nonmalignant (noncancer) pain. We investigated the benefits, harms, cost-effectiveness, and budget impact of these systems compared with current standards of care for adult patients with chronic pain owing to nonmalignant conditions. We searched Ovid MEDLINE, Ovid Embase, the Cochrane Library, and the National Health Service's Economic Evaluation Database and Tufts Cost-Effectiveness Analysis Registry from January 1994 to April 2014 for evidence of effectiveness, harms, and cost-effectiveness. We used existing systematic reviews that had employed reliable search and screen methods and also searched for studies published after the search date reported in the latest systematic review to identify studies. Two reviewers screened records and assessed study validity. We found comparative evidence of effectiveness and harms in one cohort study at high risk of bias (≥ 3-year follow-up, N = 130). Four economic evaluations of low to very low quality were also included. Compared with oral opioid analgesia alone or a program of analgesia plus rehabilitation, intrathecal drug delivery systems significantly reduced pain (27% additional improvement) and morphine consumption. Despite these reductions, intrathecal drug delivery systems were not superior in patient-reported well-being or quality of life. There is no evidence of superiority of intrathecal drug delivery systems over oral opioids in global pain improvement and global treatment satisfaction. Comparative evidence of harms was not found. Cost-effectiveness evidence is of insufficient quality to assess the appropriateness of funding intrathecal drug delivery systems. Evidence comparing intrathecal drug delivery systems with standard care was of very low quality. Current evidence does not establish (or rule out) superiority or cost-effectiveness of intrathecal drug delivery systems for managing chronic refractory nonmalignant pain

    Although the plasma technology has long been applied to treat contact lenses, the effect of this treatment on the performance of drug-loaded contact lenses is still unclear. The objective of this work is to study the effect of nitrogen plasma treatment on two drug-loaded polymeric formulations which previously demonstrated to be suitable for therapeutic contact lenses: a poly-hydroxyethylmethacrylate (pHEMA) based hydrogel loaded with levofloxacin and a silicone-based hydrogel loaded with chlorhexidine. Modifications of the surface and the optical properties, and alterations in the drug release profiles and possible losses of the antimicrobial activities of the drugs induced by the plasma treatment were assessed. The results showed that, depending on the system and on the processing conditions, the plasma treatment may be beneficial for increasing wettability and refractive index, without degrading the lens surface. From the point of view of drug delivery, plasma irradiation at moderate power (200 W) decreased the initial release rate and the amount of released drug, maintaining the drug activity. For lower (100 W) and higher powers (300 W), almost no effect was detected because the treatment was, respectively, too soft and too aggressive for the lens materials. © 2014 Wiley Periodicals, Inc.

    Different algorithms have been developed to standardize the causality assessment of adverse drug reactions (ADR). Although most share common characteristics, the results of the causality assessment are variable depending on the algorithm used. Therefore, using 10 different algorithms, the study aimed to compare inter-rater and multi-rater agreement for ADR causality assessment and identify the most consistent to hospitals. Using ten causality algorithms, four judges independently assessed the first 44 cases of ADRs reported during the first year of implementation of a risk management service in a medium complexity hospital in the state of Sao Paulo (Brazil). Owing to variations in the terminology used for causality, the equivalent imputation terms were grouped into four categories: definite, probable, possible and unlikely. Inter-rater and multi-rater agreement analysis was performed by calculating the Cohen´s and Light´s kappa coefficients, respectively. None of the algorithms showed 100% reproducibility in the causal imputation. Fair inter-rater and multi-rater agreement was found. Emanuele (1984) and WHO-UMC (2010) algorithms showed a fair rate of agreement between the judges (k = 0.36). Although the ADR causality assessment algorithms were poorly reproducible, our data suggest that WHO-UMC algorithm is the most consistent for imputation in hospitals, since it allows evaluating the quality of the report. However, to improve the ability of assessing the causality using algorithms, it is necessary to include criteria for the evaluation of drug-related problems, which may be related to confounding variables that underestimate the causal association.

    Diabetic ulcers are chronic nonhealing ulcerations that despite the available medical tools still result in high amputation rates. Growing evidence suggests that alteration of the biochemical milieu of the chronic wound plays a significant role in impaired diabetic wound healing. The basic pathophysiology and the conventional treatment strategy of diabetic foot ulcers have been reviewed in the first section. In the second part, the most up-to-date bench and translational research in the field are described. The third section focuses on the drugs currently under development and the ongoing clinical trials evaluating their safety and efficacy. Finally, the major drug development issues and the possible scientific approaches to overcome them are analyzed. Significant strides in understanding the chronic wound development have led to the development of topical therapies to address aberrant expression of growth factors and overexpression of inflammatory cytokines. Current research in the laboratory suggests that while decreased growth factor expression occurs at the local wound level, increased systemic serum levels of growth factors suggest growth factor resistance.

    Replacement therapy with clotting factor concentrates is the most appropriate and effective way to treat bleedings of Hemophilia A&B to prevent chronic arthropathy. Unfortunately, the short half-life (HL) of FVIII/IX concentrates obliges the patients to receive frequent infusions, a big concern for children. The development of inhibitors in about 30-45% of hemophilia A and in 3-5% of hemophilia B patient is the major adverse event of replacement therapy. In the last few years, new rFIX have been developed with HL. New rFVIII concentrates are displaying small increase of PK characteristics. The new bio-engineering methods allowed the production of molecules fused with Fc fragment of IgG or Albumin or linked to PEG. A new approach to improve hemostasis is represented by Mab against TFPI and small RNA interfering with Antithrombin synthesis. Another innovative drug seems to be the new bi-specific antibody which mimics FVIII function in linking FXa and FX to tenase production. The emerging drugs for hemophilia treatment seem to be very promising. The extended half-life will improve the adherence of patients to therapy. Accurate post-marketing surveillance studies will be necessary to check the efficacy, safety and immunogenicity of these new molecules.

    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).

    The internment process in therapeutic communities (TC) involves a multiplicity of therapeutic practices and strategies geared to abstinence from drug usage. According to the specialists' own regulations and explicit objectives, the residents must not only abandon the consumption of substances but also adopt new practices, attitudes, emotions and significances through the use of therapeutic techniques that allow them to adapt to the structure of the organization that these institutions impose. Based on the results of the ethnographic survey carried out between 2009 and 2010 in three TCs of the metropolitan area of Buenos Aires, Argentina, the scope of this article is to analyze from a sociological and anthropological standpoint the "therapeutic tools" that comprise the treatment, the subject models that underlie these tools, the consequences that they may produce and their participation in the subjectivity production processes. For this purpose, we focus on analysis of "confrontation" as a privileged and omnipresent strategy of subjectivation in these therapeutic contexts, in order to reveal the epistemological, economic, political and ethical dimensions in the de-subjectivation process of the institutionalized drug user.

    2016-01-01

    Dry eye disease (DED) is an inflammatory disorder of ocular surfaces leading to severe disability, especially in the elderly age group. The mainstay of therapy includes artificial tears, punctual plugs, topical anti-inflammatory agents, and corticosteroids. In the past few years, only cyclosporine-A emulsions have been added to the existing therapy, but it is discontinued by most patients as it causes burning sensation in the eye. Hence, progress in new research for a better therapeutic option led to the discovery of lymphocyte function-associated antigen intercellular adhesion molecule 1 antagonist, lifitegrast. It hinders the T-cell activation, release of inflammatory mediators, and consequently inhibits the inflammatory pathways in DED. It was approved by the US Food and Drug Administration in July 2016 for the treatment of DED. This review highlights the development process and approval of lifitegrast.

    Hemolytic ocular film (HOF) represents a polymer-based "puff pastry" whose external layers contain antioxidant emoxipine and the internal layer contains an immobilized thrombolytic enzyme; such a structure ensures a successive multifunctional effect on the main components of pathogenesis: lipid peroxidation, local hemostasis, fibrinolysis, and immune system of patients with vascular abnormalities of the eyes. The drug was used in the treatment of 248 patients with intraocular hemorrhages of traumatic origin. Control group (150 patients with the same condition) was treated traditionally. Application of HOF resulted in complete or almost complete lysis of the blood in 95% of patients; in 5% the effect was null. Traditional therapy helped attain complete lysis of the blood in 9% and partial in 43% of patient; in 48% of patients the effect was null.

    In Spain, hospital medicines are assessed and selected by local Pharmacy and Therapeutics committees (PTCs). Of all the drugs assessed, cancer drugs are particularly important because of their budgetary impact and the sometimes arguable added value with respect to existing alternatives. This study analyzed the PTC drug selection process and the main objective was to evaluate the degree of compliance of prescriptions for oncology drugs with their criteria for use. This was a retrospective observational study (May 2007 to April 2010) of PTC-assessed drugs. The variables measured to describe the committee's activity were number of drugs assessed per year and number of drugs included in any of these settings: without restrictions, with criteria for use, and not included in formulary. These drugs were also analyzed by therapeutic group. To assess the degree of compliance of prescriptions, a score was calculated to determine whether prescriptions for bevacizumab, cetuximab, trastuzumab, and bortezomib were issued in accordance with PTC drug use criteria. The PTC received requests for inclusion of 40 drugs, of which 32 were included in the hospital formulary (80.0%). Criteria for use were established for 28 (87.5%) of the drugs included. In total, 293 patients were treated with the four cancer drugs in eight different therapeutic indications. The average prescription compliance scores were as follows: bevacizumab, 83% for metastatic colorectal cancer, 100% for metastatic breast cancer, and 82.3% for non-small-cell lung cancer; cetuximab, 62.0% for colorectal cancer and 50% for head and neck cancer; trastuzumab, 95.1% for early breast cancer and 82.4% for metastatic breast cancer; and bortezomib, 63.7% for multiple myeloma. The degree of compliance with criteria for use of cancer drugs was reasonably high. PTC functions need to be changed so that they can carry out more innovative tasks, such as monitoring conditions for drug use.

    Stroke patients with dysphagia often depend on nutrition, hydration and medication via nasogastric (NG) feeding tubes. Securing tubes using tape is associated with repeated tube loss. In this study, the authors determined cause and effect by auditing tube placement methods, delays incurred, duration and costs. Of 202 NG tube placements in 75 patients, 67 placements occurred in 17 patients over a full course of enteral nutrition (EN) and 40 of these placements were tracked. Tubes were secured by tape in 100%, mittens 31% and special observation 5.4%. However, over an EN course, inadvertent tube loss occurred in 82% of patients and was associated with age (p=0.049) and mitten use (ptubes were lost due to patients and 9% slipped. Average 'tube life' was 2 days, less than 25% of the EN episode (ptube placement occurred within 2.55 hours of request, X-ray confirmation led to a delay in feed and drugs of 8-9 hours per tube placement and loss of 18.8% of feeding time per EN episode. Delays exceeded the 1-hour and 4-hour limits for antibiotics and other medicines in 20% and 80%, respectively. In the 17 tracked patients, it was estimated that 55% of the £5979 direct costs could be saved by nasal bridle use. In conclusion, most tubes studied were lost to inadvertent tube removal, leading to clinically significant delays to nutrition, hydration and drug treatments; this may impair recovery. Reducing tube loss is likely to reduce patient distress, treatment cost and enhance recovery.

    This study was aimed at designing a questionnaire for the assessment of addiction-related core beliefs and craving. The sample comprised 215 patients (85.8% males and 14.2% females) in treatment for dependence to alcohol (40%), cocaine (36.3%) and cannabis (23.7%). Descriptive statistics were used to characterize the sample. Variance, regression and factorial analyses were conducted to study the questionnaire structure and its relation with variables such as abstinence and craving. Items about drug-related beliefs yielded a four-factor structure: what patient think that they could not do without drug use, lack of withdrawal, conditions required to use drugs again, and use of drugs as the only way to feel good. Items related to craving yielded three factors: negative emotions as precipitants of drug use, positive emotions, and difficulties attributed to coping with craving. Furthermore, beliefs were more important to predict craving than abstinence time. The present questionnaire allows to assess a set of significant factors to design prevention relapse programs.

    Changes in blood pressure (BP) are now proactively examined throughout the drug development process as an integral aspect of safety monitoring. This is because hypertension is a very strong risk factor for cardiovascular events and drug-induced increases in BP have attracted increased regulatory attention. However, there is currently no guidance from regulatory agencies on the minimum BP data required for submissions, and there are no specific criteria for what constitutes a safety signal for increased BP in non clinical studies. Areas covered: Evaluation of BP increases through the drug discovery and development process. Expert opinion: Research into the effects of drugs should begin before clinical development is initiated and continue throughout the clinical trial program. Non clinical studies should inform a benefit-risk analysis that will aid decision-making of whether to enter the drug into Phase I development. The degree of acceptable risk will vary according to the therapy area, treatment indication and intended population for the new drug, and the approach to BP assessment and risk mitigation should be tailored accordingly. However, BP monitoring should always be included in clinical trials, and data collected from multiple studies, to convincingly prove or refute a suspicion of BP effects.

    The assessment of autism spectrum disorder (ASD) is complex and remains clinical, despite advances in basic research. In this chapter, we review new and updated clinical tools, such as screening and diagnostic tests, and discuss the DSM-5 criteria introduced in 2013. We provide an algorithm to guide clinical evaluation and referrals. We also review non-behavioral treatments and summarize recent research. Current conventional treatment of ASD in children includes intensive behavioral interventions (known as applied behavioral analysis or ABA), rehabilitative services such as speech therapy, occupational therapy, physical therapy, social skills training, and counseling. We present new validated information and provide clinical guidance for the evaluation and treatment of young children and youth with ASD.

    Opioids are the most frequently used drugs to treat pain in cancer patients. In some patients, however, opioids can cause adverse effects and drug-drug interactions. No advice concerning the combination of opioids and other drugs is given in the current European guidelines. To identify studies that report clinically significant drug-drug interactions involving opioids used for pain treatment in adult cancer patients. Systematic review with searches in Embase, MEDLINE, and Cochrane Central Register of Controlled Trials from the start of the databases (Embase from 1980) through January 2014. In addition, reference lists of relevant full-text papers were hand-searched. Of 901 retrieved papers, 112 were considered as potentially eligible. After full-text reading, 17 were included in the final analysis, together with 15 papers identified through hand-searching of reference lists. All of the 32 included publications were case reports or case series. Clinical manifestations of drug-drug interactions involving opioids were grouped as follows: 1) sedation and respiratory depression, 2) other central nervous system symptoms, 3) impairment of pain control and/or opioid withdrawal, and 4) other symptoms. The most common mechanisms eliciting drug-drug interactions were alteration of opioid metabolism by inhibiting the activity of cytochrome P450 3A4 and pharmacodynamic interactions due to the combined effect on opioid, dopaminergic, cholinergic, and serotonergic activity in the central nervous system. Evidence for drug-drug interactions associated with opioids used for pain treatment in cancer patients is very limited. Still, the cases identified in this systematic review give some important suggestions for clinical practice. Physicians prescribing opioids should recognize the risk of drug-drug interactions and if possible avoid polypharmacy.

    The advent of new immunotherapies for the treatment of metastatic melanoma has resulted in various novel combination strategies. Because of their distinct modes of action, different immunotherapies have been investigated in combination with one another, as well as combined with targeted therapies and other treatment modalities. Anti-CTLA-4 and anti-PD-1 treatments enhance antitumor immunity through complementary and non-redundant mechanisms. The combination of the anti-CTLA-4 agent ipilimumab and the anti-PD-1 agent nivolumab has been shown to improve progression-free survival and objective response rate compared with either agent alone as monotherapy in patients with advanced melanoma. However, the combination was associated with significant toxicity, with around one-third of patients discontinuing treatment as a result. The sequential use of nivolumab and ipilimumab was associated with similar outcomes and comparable toxicity to concurrent therapy. Clinical trials assessing various combinations of immunomodulating antibodies are ongoing or planned. Ipilimumab and pembrolizumab have also been investigated in combination with the oncolytic virus, talimogene laherparepvec (T-VEC), with promising results. In addition, immunotherapies have also been combined with chemotherapy, radiotherapy and electrochemotherapy. Investigation of combination approaches represents the start of a new story that begins with melanoma treatment and expands to embrace other solid and hematological cancers.

    Chronic substance abuse is recognized to affect nutritional status and is associated with nutrient deficiencies and malnutrition. This study aimed to identify the prevalence of malnutrition and nutritional risk factors using a spread of measurements in patients undergoing alcohol and drug treatment. Sixty-seven patients (48 male, 19 female) admitted to a public hospital detoxification unit participated: 49 were alcohol dependent (73%) and the remaining were opiate, benzodiazepine, and/or amphetamine dependent. Nutritional status was assessed by the Subjective Global Assessment. An appetite questionnaire (Simplified Nutritional Appetite Questionnaire), a diet-quality questionnaire (Australian Recommended Food Score), and blood biochemistry and hematologic tests were also applied. The prevalence of mild/moderate malnutrition was 24% according to the Subjective Global Assessment. Weight and body mass index were associated with nutritional status (P prevalence of malnutrition in this patient population is likely to underestimate the prevalence of nutritional risk factors and micronutrient undernutrition. Multiple tools assessing nutritional status, appetite, diet quality, and blood test results have different advantages and can further identify the specific needs and appropriateness of nutritional education in patients during treatment for drug and alcohol use.

    Soil-transmitted helminth (STH) infections (i.e., Ascaris lumbricoides, hookworm, and Trichuris trichiura) affect more than a billion people. Preventive chemotherapy (i.e., repeated administration of anthelmintic drugs to at-risk populations), is the mainstay of control. This strategy, however, does not prevent reinfection. We performed a systematic review and meta-analysis to assess patterns and dynamics of STH reinfection after drug treatment. We systematically searched PubMed, ISI Web of Science, EMBASE, Cochrane Database of Systematic Reviews, China National Knowledge Infrastructure, WanFang Database, Chinese Scientific Journal Database, and Google Scholar. Information on study year, country, sample size, age of participants, diagnostic method, drug administration strategy, prevalence and intensity of infection pre- and posttreatment, cure and egg reduction rate, evaluation period posttreatment, and adherence was extracted. Pooled risk ratios from random-effects models were used to assess the risk of STH reinfection after treatment. Our protocol is available on PROSPERO, registration number: CRD42011001678. From 154 studies identified, 51 were included and 24 provided STH infection rates pre- and posttreatment, whereas 42 reported determinants of predisposition to reinfection. At 3, 6, and 12 months posttreatment, A. lumbricoides prevalence reached 26% (95% confidence interval (CI): 16-43%), 68% (95% CI: 60-76%) and 94% (95% CI: 88-100%) of pretreatment levels, respectively. For T. trichiura, respective reinfection prevalence were 36% (95% CI: 28-47%), 67% (95% CI: 42-100%), and 82% (95% CI: 62-100%), and for hookworm, 30% (95% CI: 26-34%), 55% (95% CI: 34-87%), and 57% (95% CI: 49-67%). Prevalence and intensity of reinfection were positively correlated with pretreatment infection status. STH reinfections occur rapidly after treatment, particularly for A. lumbricoides and T. trichiura. Hence, there is a need for frequent anthelmintic drug administrations to

    Although several critiques of the methodology of alcohol treatment outcome studies have been published, similar reviews of the methodology of drug treatment outcome studies are lacking. This paper reviews the methodology of drug treatment outcome studies published from 1993 through 1997 and draws comparisons with the most recent methodological review of alcohol treatment outcome studies. Each drug study was evaluated as to whether the following types of data were reported: (1) demographic, (2) drug use, (3) study characteristics, and (4) outcome and follow-up information. Although results for drug studies showed some areas of strength compared to alcohol studies, in general, the weaknesses were similar to or worse than in the alcohol field, including inadequate reporting of demographic and drug use variables. Weaknesses in follow-up procedures were particularly notable. Suggestions for improving the reporting of methodological and outcome variables for drug treatment outcome studies are discussed.

    This survey was performed to determine the relationship between the adherence to hypertension drug treatment and the perception of stress, depression, hypertension, and myocardial infarction. 300 patients with uncomplicated hyperten- sion from Rijeka, Croatia, were included (131 women, 169 men, mean age 53.5 years). Adherence to hypertension drug treatment as criterion, and the perception of stress, depression hypertension and myocardial infarction as prediclors were determined by self-assessment. Collected data were analysed using factor analysis, regression analysis, Kolmogorov-Smirnov test, chi2-test and t-test. The statistical significance was set at a probability rate of less than 5% (p perceived potency of hypertension and the negative were perceived helplessness in stress control and negative thoughts and emotions. The positive predictors of knowledge about taking antihypertensives were perceived helplessness in stress control, perceived potency of hypertension and myocardial infarction and the negative predictors were perceived self-efficacy in stress control, physiological disturbances and evaluation of hypertension. Both the motivation as well as the knowledge about taking antihypertensives should be improved, especially in women. The perception of stress, depression, hypertension and myocardial infarction can be used to predict adherence to hypertension drug treatment.

    Denial of human rights, gender disparities, and living in a war zone can be associated with severe depression and poor social functioning, especially for female drug abusers. This study of Afghan women in drug abuse treatment (DAT) centers assesses (a) the extent to which these women have experienced human rights violations and mental health problems prior to entering the DAT centers, and (b) whether there are specific risk factors for human rights violations among this population. A total of 176 in-person interviews were conducted with female patients admitted to three drug abuse treatment centers in Afghanistan in 2010. Nearly all women (91%) reported limitations with social functioning. Further, 41% of the women indicated they had suicide ideation and 27% of the women had attempted suicide at least once 30 days prior to entering the DAT centers due to feelings of sadness or hopelessness. Half of the women (50%) experienced at least one human rights violation in the past year prior to entering the DAT centers. Risk factors for human rights violations among this population include marital status, ethnicity, literacy, employment status, entering treatment based on one's own desire, limited social functioning, and suicide attempts. Conclusions stemming from the results are discussed.

    Dopamine receptors (DR) have been extensively studied, but only in recent years they became object of investigation to elucidate the specific role of different subtypes (D1R, D2R, D3R, D4R, D5R) in neural transmission and circuitry. D1-like receptors (D1R and D5R) and D2-like receptors (D2R, D2R and D4R) differ in signal transduction, binding profile, localization in the central nervous system and physiological effects. D3R is involved in a number of pathological conditions, including schizophrenia, Parkinson's disease, addiction, anxiety, depression and glaucoma. Development of selective D3R ligands has been so far challenging, due to the high sequence identity and homology shared by D2R and D3R. As a consequence, despite a rational design of selective DR ligands has been carried out, none of currently available medicines selectively target a given D2-like receptor subtype. The availability of the D3R ligand [(11)C]-(+)-PHNO for positron emission tomography studies in animal models as well as in humans, allows researchers to estimate the expression of D3R in vivo; displacement of [(11)C]-(+)-PHNO binding by concurrent drug treatments is used to estimate the in vivo occupancy of D3R. Here we provide an overview of studies indicating D3R as a target for pharmacological therapy, and a review of market approved drugs endowed with significant affinity at D3R that are used to treat disorders where D3R plays a relevant role.

With this aim in mind a sample of 209 patients who had applied for treatment were selected and assessed inthe principal object areas of analysis over a period of ayear anda half at six monthly intervals.The results indicate that time spent in a therapeutic centre significantly reduces criminal behaviour. However, those patients with a greater past history present more difficulties and give a poorer initial response, although during the period of follow-up these differences tend to disappear.

    The objective of this study is to investigate drug treatment patterns in bipolar disorder using daily data from patients who received treatment as usual. Patients self-reported the drugs taken daily for about 6 months. Daily drug use and drug combinations were determined for each patient, both by the specific drugs and by medication class. The drug load was calculated for all drugs taken within a medication class. Four hundred fifty patients returned a total of 99,895 days of data (mean 222.0 days). The most frequently taken drugs were mood stabilizers. Of the 450 patients, 353 (78.4%) took a stable drug combination for ≥50% of days. The majority of patients were taking polypharmacy, including 75% of those with a stable combination. Only a small number of drugs were commonly taken within each medication class, but there were a large number of unique drug combinations: 52 by medication class and 231 by specific drugs. Eighty percent of patients with a stable combination were taking three or less drugs daily. Patients without a stable combination took drugs but made frequent changes. Taking more than one drug within a medication class greatly increased the drug load. To summarize, (1) patients were more likely to take a mood stabilizer than any other drug; (2) although most patients were taking polypharmacy, there were no predominant drug regimens even among those taking a stable combination; and (3) most patients with a stable combination take a relatively small number of drugs daily. The wide variation in drug regimens and numerous possible drug combinations suggest that more evidence is needed to optimize treatment of bipolar disorder.

    The aim of this study was to assess drop-out rates and associated reasons among patients at the Iranian National Center for Addiction Studies (INCAS) clinic. In a one-year period (April 2014 to March 2015), all patients with drug dependence who had been referred for treatment and attended for a first assessment were included in this study (N=242). Those who received treatment were followed until March 2016. Survival analysis showed that 70.2% had dropped out from treatment. Log rank test showed that treatment drop-out rates differed between the different approaches used (P < 0.001), with the lowest slope inbuprenorphine maintenance treatment and the highest in the detoxification programme. Drop-out rates within the first three months was 62% (SE= 0.05) and 82.4% (SE=0.03) for opioids and stimulants dependence, respectively. Analyses were performed using SPSS (Version 21.0) and STATA software, (version 13.0). From the patients' perspective, motivational inconsistencies were considered as the main reason for not starting or leaving treatment. The findings of this study could give service providers a better grasp of drop-out rates and the associated reasons.

    Until May 31, 2015 the German Institute for Quality and Efficiency in Health Care (IQWiG) conducted 108 assessments for various diseases on the basis of 103 dossiers within the scope of the early benefit assessment of drugs pursuant to the Act on the Reform of the Market for Medicinal Products (AMNOG). 29 of these assessments (28 dossiers) referred to advanced stages of oncologic (including neoplastic-hematologic) diseases. In 21 of these 29 assessments (72%), IQWiG found an added benefit for at least one subpopulation or subgroup, compared to 33% with non-oncologic diseases. For oncologic diseases, the extent of benefit was classified as "major" in six assessments (21%), compared to 5% for non-oncologic disorders. In contrast, the conclusions of the oncologic studies were less certain: only one assessment provided proof (of an added benefit); for non-oncologic diseases, this was the case in eight assessments. A distinctive methodological feature of the available oncologic studies is that, as a rule, treatment switching was planned in the event of progression (normally on the basis of imaging or laboratory findings) and that shortly afterwards the follow-up of important endpoints (adverse events and patient-reported outcomes) was normally discontinued. In particular, the pre-specified option in the study protocol allowing the control group to switch treatment to the experimental intervention after progression ("protocol-permitted treatment switches") makes it extremely difficult to interpret the results beyond the outcome "progression" (or progression-free survival). This treatment switching is mostly justified by reference to ethical necessity. This, however, alleges that the experimental intervention (i. e., the new drug) is superior to the control intervention, which means that circular reasoning is unavoidable. But despite this, oncologic studies are better than their reputation. Hence, so far the results of the early benefit assessment of new drugs (regarding

    Immunosuppressive drugs have been used in the treatment of multiple sclerosis (MS) for a long time. Today, orally available second generation immunosuppressive agents have been approved or are filed for licensing as MS therapeutics. Due to semi-selective targeting of cellular processes, these second-generation immunosuppressive compounds might rather be immunomodulatory. For example, Teriflunomide inhibits the de novo pyrimidine synthesis and thus only targets rapidly proliferating cells, including lymphocytes. It is used as first line disease modifying therapy (DMT) in relapsing-remitting MS (RRMS). Review of online content related to oral immunosuppressants in MS with an emphasis on Teriflunomide. Teriflunomide and Cladribine are second-generation immunosuppressants that are efficient in the treatment of MS patients. For Teriflunomide, a daily dose of 14 mg reduces the annualized relapse rate (ARR) by more than 30% and disability progression by 30% compared to placebo. Cladribine reduces the ARR by about 50% compared to placebo but has not yet been licensed due to unresolved safety concerns. We also discuss the significance of older immunosuppressive compounds including Azathioprine, Mycophenolate mofetile, and Cyclophosphamide in current MS therapy. Teriflunomide has shown a favorable safety and efficacy profile in RRMS and is a therapeutic option for a distinct group of adult patients with RRMS.

    The risk of interaction between dietary supplements, herbal drugs and synthetic drugs increases when patients are treated chronically, e.g. due to impairment of central nervous system (CNS)--depression, psychotic disorders, Parkinson's and Alzheimer's diseases. On the basis of scientific literature, there was shown that simultaneous intake of antidepressants, antipsychotic drugs and herbal drugs or dietary supplements containing: St. John's wort, valerian root, ginkgo biloba leaf, hops, and food ingredients: dietary fiber or folic acid, may lead to interactions. Dietary fiber supplementation should be applied carefully during treatment of Parkinson's disease and in case of Alzheimer disease treatment--supplements containing ginkgo biloba leaf can increase the risk of interaction. Knowledge of these interactions is essential in effective treatment of this illness. However this area of science should be verified constantly due to growing number of new products registered as a supplements--often with complex composition.

    Many offenders participate in drug abuse treatment programs while in prison or on probation or parole. Among other benefits, this treatment may lessen the risk of recidivism. Thus, understanding counselor treatment philosophy is important as their attitudes toward treatment can be influential in the strategies they use and ultimately affect treatment outcomes. Analyzing data from 110 drug abuse treatment counselors, this study compared counselors' perceptions of causation of drug abuse and treatment strategy between faith-based and secular treatment programs. It was found that counselors from faith-based programs were more likely to endorse religious models and less prone to support disease models as an explanation of drug use. With regard to treatment strategy, counselor's group affiliation was not predictive of a focus on either a client religious need or a medical treatment model. Nevertheless, the extent of counselor's religiosity was correlated with tackling clients' religious needs as a treatment strategy. On the other hand, certified (licensed) counselors were found to be more supportive of the medical model as a treatment approach. Limitations of the current study and policy implications are discussed.

    Life cycle assessment was conducted to estimate the environmental impact of electronic waste (e-waste) treatment. E-waste recycling with an end-life disposal scenario is environmentally beneficial because of the low environmental burden generated from human toxicity, terrestrial ecotoxicity, freshwater ecotoxicity, and marine ecotoxicity categories. Landfill and incineration technologies have a lower and higher environmental burden than the e-waste recycling with an end-life disposal scenario, respectively. The key factors in reducing the overall environmental impact of e-waste recycling are optimizing energy consumption efficiency, reducing wastewater and solid waste effluent, increasing proper e-waste treatment amount, avoiding e-waste disposal to landfill and incineration sites, and clearly defining the duties of all stakeholders (e.g., manufacturers, retailers, recycling companies, and consumers).

    Full Text Available Abstract Background Governments aim to increase treatment participation by problematic drug users. In the UK this has been achieved by fiscal investment, an expanded workforce, reduced waiting times and coercive measures (usually criminal justice (CJ led. No assessment of these measures on treatment outcomes has been made. Using established monitoring systems we assessed trends in 'dropped out' and 'discharged drug free' (DDF, since the launch of the national drug strategy, and rates of treatment re-presentation for these cohorts. Methods A longitudinal dataset of drug users (1997 to 2004/05, n = 26,415 was used to identify people who dropped out of, and were DDF from, services for years 1998 to 2001/02, and re-presentations of these people in years to 2004/05. Trends in drop out and DDF, baseline comparisons of those DDF and those who dropped out and outcome comparisons for those referred from the CJ system versus other routes of referral were examined using chi square. Logistic regression analyses identified variables predicting drop out versus DDF and subsequent re-presentation versus no re-presentation. Results The proportion of individuals dropping out has increased from 7.2% in 1998 to 9.6% in 2001/02 (P Conclusion Increasing numbers in treatment is associated with an increased proportion dropping out and an ever-smaller proportion DDF. Rates of drop out are significantly higher for those coerced into treatment via the CJ system. Rates of re-presentation are similar for those dropping out and those DDF. Encouragingly, those who need to re-engage with treatment, particularly those who drop out, are doing so more quickly. The impact of coercion on treatment outcomes and the appropriateness of aftercare provision require further consideration.

    To evaluate the effect size of type 2 diabetes mellitus (T2DM) on tuberculosis (TB) treatment outcomes and multi drug resistance (MDR). A cohort with 507 individuals with diagnosed TB included 183 with coexistence of T2DM and TB (TB-T2DM). Participants were identified at the time of TB diagnosis and followed during the course of TB treatment. Then we computed relative risks and adjustments by Cox proportional hazards for outcome variables (drug resistance, death, relapse, treatment failure), and the size of their effect as Cohen's-d. Patients with TB-T2DM were more likely to remain positive for acid-fast bacilli after two months of anti-TB treatment RR = [2.01 (95% CI: 1.3, 3.1)], to have drug resistant (DR) [OR 3.5 (95% CI: 1.8, 6.7)] and multi-drug resistant (MDR) TB [OR 3.5 (95% CI: 1.8, 7.1)]. The Cohen's-d for DR or MDR in T2DM was 0.69 when compared with non-DM subjects. The T2DM patients had higher odds of resistance to isoniazid (OR 3.9, 95% CI: 2.01, 7.9), rifampicin (OR 3.4, 95% CI: 1.6, 7.2) and pyrazinamide (OR 9.4, 95% CI: 2.8, 25.6), and their effect sizes were ≥0.67. Patients with TB-T2DM (versus no DM) were more likely to present with MDR TB (HR 3.1; 95% CI: 1.7, 5.8; p < 0.001), treatment failure (HR 2.04; 95% CI: 1.07, 3.8; p = 0.02) and relapse (HR 1.86; 95% CI: 1.09, 3.1; p = 0.02), with effect size ≥0.34. T2DM showed a substantial contribution to the presence of DR or MDR-TB and to adverse clinical outcomes during and after TB treatment. Our findings support the importance for routine screening of T2DM among newly-diagnosed TB patients in order to stratify them for immediate DR assessment, and highlight the need for clinical trials to evaluate variations to the standard TB treatment in TB-T2DM to prevent adverse treatment outcomes.

Voriconazole has been approved as first-line therapy for IA since 2003; however, nonlinear pharmacokinetics, adverse effects, and drug–drug interactions at time hinder its use. Isavuconazole is a new broad-spectrum triazole with potent activity against Aspergillus species. In animal models and clinical trials in humans, isavuconazole has shown comparable efficacy to that of voriconazole in the treatment of IA. Advantages of isavuconazole include a more favorable pharmacokinetic profile and fewer adverse events. This review summarizes the pharmacologic characteristics, in vitro activity, and clinical data supporting the use of isavuconazole as an emerging alternative therapy for IA.

    Waldenström's Macroglobulinemia (WM) is a rare, indolent, incurable, low-grade B-cell lymphoplasmacytic neoplasm. This review article provides a modern clinical perspective of the individualized management of patients with symptomatic WM, in the context of the updated treatment guidelines and the currently available trial data. Areas covered: Rituximab-based regimens (such as the dexamethasone, rituximab and cyclophosphamide combination, DRC) are the most widely used in the management of both newly diagnosed and relapsed/refractory patients with WM. Recently, the Bruton's tyrosine kinase inhibitor ibrutinib has been licensed for use in WM with exciting results. Several investigational single agent and combination regimens are being evaluated for response, efficacy and tolerability in phase II clinical trials, including new generation monoclonal antibodies (ofatumumab), immunomodulatory agents (thalidomide and lenalidomide), proteasome inhibitors (bortezomib and carfilzomib), Bruton's tyrosine kinase inhibitors (ibrutinib and acalabrutinib), phosphoinositide 3-kinase/protein kinase B (Akt)/mammalian target of rapamycin pathway inhibitors (everolimus and perifosene), and histone deacetylase inhibitors (panobinostat) both in the setting of newly diagnosed and relapsed/refractory disease. Expert opinion: WM therapeutic approach should be individualized for each patient in accordance to the intensity of the disease characteristics, age, comorbidities, efficacy, tolerability and safety profile of each drug.

    Glaucoma is the leading cause of irreversible blindness worldwide. The perspective of clinicians who treat the disease is important and may ultimately dictate the adoption of new treatment modalities, such as drug-eluting contact lenses. Recent advances have enabled contact lenses to serve as a sustained-release drug-delivery platform capable of treating glaucoma. This review covers the medical treatment of glaucoma, suboptimal adherence rates to treatment, and factors that may influence the clinical applicability of drug-eluting contact lenses. Ophthalmologists who treat glaucoma were surveyed to determine their perspective on treatment adherence, bandage contact lens use and the use of a drug-eluting contact lens to treat glaucoma. Given the challenge of treating glaucoma and the clinical need for improved drug delivery, drug-eluting contact lenses appear to be a promising treatment option.

    Little is known about attitudes toward and experiences with opioid maintenance therapy (OMT) among people who inject drugs in Malaysia, a country where people who inject drugs comprise 1.3% of the adult population. In 2010, 460 people who inject drugs in Greater Kuala Lumpur, Malaysia were surveyed to evaluate attitudes toward and experiences with OMT and treatment readiness. Attitudes towards OMT with both methadone and buprenorphine were assessed using an opinions scale. Multivariable linear regression was used to assess correlates of treatment readiness, measured with the 19-item Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES). All 460 participants used opioids and nearly all (99.1%) met criteria for opioid dependence. Few had had previous experience with methadone (9.3%) or buprenorphine (12.6%) maintenance therapy, yet many had used methadone (55.2%) or buprenorphine (51.7%) outside of treatment settings. Fifteen percent had injected buprenorphine in the past month, and of the few that were currently receiving buprenorphine maintenance therapy, almost all were injecting it. The majority of subjects exhibited a moderate level of treatment readiness and a preference for methadone over buprenorphine. Those with low treatment readiness scores were more likely to have previous experience with compulsory drug detention centers (pstress symptom severity (p<0.001), and sharing of needles or syringes (p<0.05) were associated with higher treatment readiness scores. There are suboptimal levels of OMT experience among people who inject drugs that may be improved by addressing factors that influence patient attitudes. Those individuals with moderate treatment readiness may be targeted by brief motivational and cognitive interventions in primary care, prisons or OMT clinics aimed at improving entry into and retention in treatment.

    Objective: Investigations of injecting drug users (IDUs have suggested that the social context may influence high-risk behaviours in this population. The aim of this study was to describe knowledge, attitudes and behaviours of IDUs attending public drug-treatment centres in our area.

    Study design and methods: A cross-sectional survey was conducted between July 2002 and February 2004, enrolling 607 drug users attending four public drug-treatment centres in the Palermo area. Two of them were located inside the urban area, whereas the other two were in rural districts near the city. All participants answered an anonymous questionnaire concerning social and demographic characteristic and potential high-risk behaviours.

    Results: IDUs living in urban context have a higher educational level, higher number of sexual partners, as well as a lower prevalence of exchanging sex for drugs. Conversely, IDUs living in suburban/rural context are less likely to share syringes and more likely to have used light drugs in the past. Suburban/rural IDUs drink more alcohol but smoke less cigarettes/day, although both groups are strong smokers.

    Conclusions: The results suggest that public drug-treatment centres should take in consideration the adoption of specific programs targeting specific groups, in line with the profile and needs of the subjects in each context in order to promote approaches leading to risk reduction.

    Highlights: • Life cycle assessment of electronic waste recycling is quantified. • Key factors for reducing the overall environmental impact are indentified. • End-life disposal processes provide significant environmental benefits. • Efficiently reduce the improper disposal amount of e-waste is highly needed. • E-waste incineration can generate significant environmental burden. - Abstract: Life cycle assessment was conducted to estimate the environmental impact of electronic waste (e-waste) treatment. E-waste recycling with an end-life disposal scenario is environmentally beneficial because of the low environmental burden generated from human toxicity, terrestrial ecotoxicity, freshwater ecotoxicity, and marine ecotoxicity categories. Landfill and incineration technologies have a lower and higher environmental burden than the e-waste recycling with an end-life disposal scenario, respectively. The key factors in reducing the overall environmental impact of e-waste recycling are optimizing energy consumption efficiency, reducing wastewater and solid waste effluent, increasing proper e-waste treatment amount, avoiding e-waste disposal to landfill and incineration sites, and clearly defining the duties of all stakeholders (e.g., manufacturers, retailers, recycling companies, and consumers)

  17. Embryonic Zebrafish Model - A Well-Established Method for Rapidly Assessing the Toxicity of Homeopathic Drugs - Toxicity Evaluation of Homeopathic Drugs Using Zebrafish Embryo Model -

    Full Text Available Objectives: Advancements in nanotechnology have led to nanoparticle (NP use in various fields of medicine. Although the potential of NPs is promising, the lack of documented evidence on the toxicological effects of NPs is concerning. A few studies have documented that homeopathy uses NPs. Unfortunately, very few sound scientific studies have explored the toxic effects of homeopathic drugs. Citing this lack of high-quality scientific evidence, regulatory agencies have been reluctant to endorse homeopathic treatment as an alternative or adjunct treatment. This study aimed to enhance our insight into the impact of commercially-available homeopathic drugs, to study the presence of NPs in those drugs and any deleterious effects they might have, and to determine the distribution pattern of NPs in zebrafish embryos (Danio rerio. Methods: Homeopathic dilutions were studied using high-resolution transmission electron microscopy with selected area electron diffraction (SAED. For the toxicity assessment on Zebrafish, embryos were exposed to a test solution from 4 - 6 hours post-fertilization, and embryos/larvae were assessed up to 5 days post-fertilization (dpf for viability and morphology. Toxicity was recorded in terms of mortality, hatching delay, phenotypic defects and metal accumulation. Around 5 dpf was found to be the optimum developmental stage for evaluation. Results: The present study aimed to conclusively prove the presence of NPs in all high dilutions of homeopathic drugs. Embryonic zebrafish were exposed to three homeopathic drugs with two potencies (30CH, 200CH during early embryogenesis. The resulting morphological and cellular responses were observed. Exposure to these potencies produced no visibly significant malformations, pericardial edema, and mortality and no necrotic and apoptotic cellular death. Conclusion: Our findings clearly demonstrate that no toxic effects were observed for these three homeopathic drugs at the potencies and

    Paraphilias are characterized by recurrent, intense, sexually arousing fantasies, urges, or behaviors, over a period of > or =6 months, generally involving nonhuman objects, suffering or humiliation of oneself or one's partner, or children or other nonconsenting persons. These fantasies, urges, and behaviors produce clinically significant distress or impairments in social, occupational, and other important areas of functioning. The goal of this article was to provide an in-depth review of the clinical pharmacology of the main antiandrogens (cyproterone acetate, medroxyprogesterone acetate [MPA], and the luteinizing hormone-releasing hormone [LHRH] agonists) used in the treatment of the paraphilias, as well as a discussion of the relevant clinical case reports, case series, and controlled trials. Treatment recommendations are also provided. Relevant publications were identified through a search of the English-language literature indexed on MEDLINE/PubMed (1966-September 2008) using the search terms paraphilia, sex offender, hypersexuality, sexual behaviors, fetish, transvestic fetishism, sexual addiction, sexual compulsivism, selective serotonin reuptake inhibitors, tricyclic antidepressants, antiandrogens, cyproterone acetate, medroxyprogesterone acetate, LHRH agonists, and estrogens. Additional publications were identified from the bibliographies of retrieved publications. In vitro and in vivo (animal) studies have revealed that serotonin and prolactin inhibit sexual arousal, while norepinephrine (via alpha(1)-adrenoceptor activation), dopamine, acetylcholine (via muscarinic receptor activation), enkephalins, oxytocin, gonadotropin-releasing hormone, follicle-stimulating hormone, luteinizing hormone, testosterone/dihydrotestosterone, and estrogen/progesterone stimulate it. Most of the currently used pharmacologic treatments of the paraphilias have serotonin and testosterone/dihydrotestosterone as their targets. Cognitive-behavioral psychotherapy should be

    Cetirizine is indicated for the treatment of allergic conditions such as insect bites and stings, atopic and contact dermatitis, eczema, urticaria. This investigation deals with development of a novel ethosome-based topical formulation of cetirizine dihydrochloride for effective delivery. The optimised formulation consisting of drug, phospholipon 90 G™ and ethanol was characterised for drug content, entrapment efficiency, pH, vesicular size, spreadability and rheological behaviour. The ex vivo permeation studies through mice skin showed highest permeation flux (16.300 ± 0.300 µg/h/cm(2)) and skin retention (20.686 ± 0.517 µg/cm(2)) for cetirizine-loaded ethosomal vesicles as compared to conventional formulations. The in vivo pharmacodynamic evaluation of optimised formulation was assessed against oxazolone-induced atopic dermatitis (AD) in mice. The parameters evaluated were reduction in scratching score, erythema score, skin hyperplasia and dermal eosinophil count. Our results suggest that ethosomes are effective carriers for dermal delivery of antihistaminic drug, cetirizine, for the treatment of AD.

    Benzodiazepines are frequently prescribed to patients with drug use disorders. However, it has previously been difficult to distinguish whether this frequent prescribing was due to underlying psychiatric disorders or inappropriate prescribing. In a nationwide cohort study, we investigated the prescribing of benzodiazepines to patients with drug use disorders in connection with treatment admission. Benzodiazepine prescriptions to patients (N = 33203) aged 18 to 67 years admitting for outpatient treatment for drug use disorders in Denmark, 2000 to 2010, were studied by using linked data from nationwide health registries. Factors associated with increasing amounts of benzodiazepine use within the first year after admission were assessed by multinomial logistic regression. Proportions of very long-term benzodiazepine prescription were calculated. During the first year after admission to treatment, 26.2 % of patients were prescribed benzodiazepines. Of these, 35.5 % were prescribed benzodiazepines at dose levels that might indicate inappropriate use (>365 Defined Daily Dose per year), and 34.6 % were prescribed more than one type of benzodiazepines. Diazepam was the most commonly prescribed type. Among patients with opioid use, 43.2 % were prescribed benzodiazepines which were three times higher than for patients with cannabis (12.2 %) or central stimulating drugs (13.8 %) as their primary drug use. Admitting to treatment for a drug use disorder did not increase the specialized psychiatric treatment coverage of this patient group, disregarding use of prescribed benzodiazepines. 29.5 % were new users of prescribed benzodiazepines, and of these, 27.5 % continued into very long-term use (≥4 years after admission) during the study period. Benzodiazepines were commonly prescribed to patients admitting to treatment for drug use disorders, and included prescription of multiple and non-optimal types, high doses, and very long-term prescriptions. These findings

    We reside in an era of technological innovation and advancement despite which infectious diseases like malaria remain to be one of the greatest threats to the humans. Mortality rate caused by malaria disease is a huge concern in the twenty-first century. Multiple drug resistance and nonspecific drug targeting of the most widely used drugs are the main reasons/drawbacks behind the failure in malarial therapy. Dose-related toxicity because of high doses is also a major concern. Therefore, to overcome these problems nano-based drug delivery systems are being developed to facilitate site-specific or target-based drug delivery and hence minimizing the development of resistance progress and dose-dependent toxicity issues. In this review, we discuss about the shortcomings in treating malaria and how nano-based drug delivery systems can help in curtailing the infectious disease malaria.

  7. Poststroke hypertonicity: upper limb assessment and treatment.

    Marciniak, Christina

    2011-01-01

    Hypertonicity is common in patients with upper limb dysfunction following hemiplegic stroke and is associated with greater impairment, worse function, and lower health-related quality of life. In addition to increased rest activity, abnormal patterns of muscle activation, such as spastic co-contraction, may contribute to disability. In the upper limb, flexor muscles are more commonly involved distally, and at the shoulder, spasticity of adductors, flexors, and internal rotators is most often observed. Prior to interventions, a history regarding prior interventions, comorbid diagnoses, and limitations imposed by abnormal tone should be elicited. Commonly used scales to assess hypertonicity include the Modified Ashworth, the Modified Tardieu, the Spasm Frequency, the Disability Assessment, the Fugl-Meyer, and the Motor Assessment Scales. Treatment interventions for upper limb hypertonicity include stretching, splinting, strengthening of antagonist muscles, oral medications, and focal injections (phenol or botulinum toxins). Intrathecal baclofen may also impact upper limb tone. For focal injections, correct identification of muscles contributing to problematic tone is evaluated by eliciting resistance to movement at rest and observation of patterns of tightness as the limb is used functionally. The botulinum toxins have been shown to decrease tone in stroke survivors and improve active and passive functioning. Because secondary changes such as contractures and weakness may occur with prolonged hypertonicity, therapy to improve range of motion, strengthen weakened muscles, and incorporate use of the limb should be considered following focal injections, oral medications, or intrathecal pump placement.

    This study describes early treatment drug use status and associated clinical characteristics in a diverse sample of patients entering outpatient substance abuse psychosocial counseling treatment. The goal is to more fully characterize those entering treatment with and without active use of their primary drug in order to better understand associated treatment needs and resilience factors. We examined baseline data from a NIDA Clinical Trials Network (CTN) study (Web-delivery of Treatment for Substance Use) with an all-comers sample of patients (N = 494) entering 10 outpatient treatment centers. Patients were categorized according to self-identified primary drug of abuse (alcohol, cocaine/stimulants, opioids, marijuana) and by baseline drug use status (positive/negative) based on urine testing or self-reports of recent use (alcohol). Characteristics were examined by primary drug and early use status. Classified as drug-negative were 84%, 76%, 62%, and 33% of primary opioid, stimulant, alcohol, and marijuana users; respectively. Drug-positive versus -negative patients did not differ on demographics or rates of substance abuse/dependence diagnoses. However, those negative for active use had better physical and mental health profiles, were less likely to be using a secondary drug, and were more likely to be attending 12-step self-help meetings. Early treatment drug abstinence is common among substance users entering outpatient psychosocial counseling programs, regardless of primary abused drug. Abstinence (by negative UA) is associated with better health and mental health profiles, less secondary drug use, and more days of 12-step attendance. These data highlight differential treatment needs and resiliencies associated with early treatment drug use status. NCT01104805.

    2017-02-01

    Full Text Available In recent years, glucose-sensitive drug delivery systems have attracted considerable attention in the treatment of diabetes. These systems can regulate payload release by the changes of blood glucose levels continuously and automatically with potential application in self-regulated drug delivery. Boronic acid (BA, especially phenylboronic acid (PBA, as glucose-sensitive agent has been the focus of research in the design of glucose-sensitive platforms. This article reviews the previous attempts at the developments of PBA-based glucose-sensitive drug delivery systems regarding the PBA-functionalized materials and glucose-triggered drug delivery. The obstacles and potential developments of glucose-sensitive drug delivery systems based on PBA for diabetes treatment in the future are also described. The PBA-functionalized platforms that regulate drug delivery induced by glucose are expected to contribute significantly to the design and development of advanced intelligent self-regulated drug delivery systems for treatment of diabetes.

    Recent reports indicate that a variety of light-based devices have been used for acne treatment and skin rejuvenation. A new technology combining intense pulsed light with negative pressure, photopneumatic technology, has recently attracted interest. The present study assessed acne treatment and skin rejuvenation with this novel approach Subjects and Methods: Acne, 450 nm tip. Five Japanese volunteers (1 male, 4 female; mean age 28.6 yr; skin type III) with mild to moderate/moderate active acne participated. The face was treated with 2 sessions, 2 weeks apart. Biopsies were obtained immediately after the first session and 1 week after the second session, and routinely processed for transmission electron microscopy (TEM). Rejuvenation, profusion tip with topical preparation . In 5 Japanese volunteers (3 male, 2 female; mean age 37.6 yr, skin type III), the volar aspect of both forearms was treated with the 530 nm head at P6 (around 12 J/cm(2)). The left arm was then treated with a pre-infused profusion tip and vacuum only. Four sessions were given, 14-day intervals. Biopsies were taken from both arms 2 weeks after the 2nd session and 3 weeks after the 4th session. One-half of each biopsy was assessed with histo-and immunohistochemistry, and the other with TEM. Acne trial: A combination of physical extraction of comedones, mild photothermal damage of the follicle and damage to identified bacilli was noted post-treatment, with macroscopic improvement of the skin. Rejuvenation with profusion: Significant morphological and immunohistochemical differences were seen between the control and profusion-treated arms at the first assessment. These differences became less significant at the 2nd assessment. Macroscopically and histologically, photopneumatic technology improved acne lesions, suggesting a synergistic effect between the components of the technology. In skin rejuvenation, the profusion therapy accelerated the regenerative process, and could have excellent additional

    Globally, patterns of the use of psychoactive substances have been changing. To evaluate the trend in two five year periods, 1992 to 1997 versus 2002 to 2007, of alcohol and substance use disorders and associated variables in patients admitted to a drug abuse treatment facility. This was a comparative cross-sectional study involving all patients admitted into Drug Abuse Treatment, Education, and Research (DATER), Unit of the Neuropsychiatric Hospital, Aro, Nigeria within the study period. All subjects had a structured psychiatric interview, a physical examination, laboratory investigations and DATER Questionnaire protocols that elicited socio-demographic, drug and family variables. The patients in 2002 to 2007 versus those of 1992 to 1997 were younger (chi squared 13.29; p,0.01). More last borns were using drugs by 2002 to 2007 (chi squared, 11.37; p,0.01). Cannabis was the most abused drug in 2002 to 2007 (53.5%) as compared to cocaine (44%) in 1992 to 1997 (chi squared 35.5; p,0.001). Polydrug abuse was high in the two periods but significantly the drug combination changed to cannabis in combination with alcohol in 2002 to 2007 as against cocaine in combination with opiates in 1992 to 1997 chi squared 45.3, p 0.001). More patients had co-morbid psychiatric disorders in 2000 to 2007 (67.6% as against 38.5% in 1992 to 1999 chi squared 28.32, p,0.001). In both periods, co-morbidity associated with cannabis use rather than any other drug of abuse as the odds ratio was greater than one. The findings in the trend in the two five year periods underscore the imperatives of continuous evaluation of the drug abuse patient population in treatment which may help drive changes in treatment inputs.

    Experimental research over just the past decade has raised the possibility that learning deficits connected to Down syndrome (DS) might be effectively managed by medication. In the current chapter, we touch on some of the work that paved the way for these advances and discuss the challenges associated with translating them. In particular, we highlight sources of phenotypic variability in the DS population that are likely to impact performance assessments. Throughout, suggestions are made on how to detect meaningful changes in cognitive-adaptive function in people with DS during drug treatment. The importance of within-subjects evaluation is emphasized.

  18. Does the Drug Facts Label for nonprescription drugs meet its design objectives? A new procedure for assessing label effectiveness

    Directory of Open Access Journals (Sweden)

    Michael P Ryan

    2017-07-01

    Full Text Available We demonstrate an expanded procedure for assessing drug-label comprehension. Innovations include a pretest of drug preconceptions, verbal ability and label attentiveness measures, a label-scanning task, a free-recall test, category-clustering measures, and preconception-change scores. In total, 55 female and 39 male undergraduates read a facsimile Drug Facts Label for aspirin, a Cohesive-Prose Label, or a Scrambled-Prose Label. The Drug Facts Label outperformed the Scrambled-Prose Label, but not the Cohesive-Prose Label, in scanning effectiveness. The Drug Facts Label was no better than the Cohesive-Prose Label or the Scrambled-Prose Label in promoting attentiveness, recall and organization of drug facts, or misconception refutation. Discussion focuses on the need for refutational labels based on a sequence-of-events text schema.

    In an effort to mitigate Kentucky's prescription drug misuse, legislative intervention efforts were introduced in 2012 and 2013 to better regulate pain clinics, prescribed use of opioid analgesics, and to expand the monitoring of opioid prescriptions. The focus of this paper is primarily on opioid analgesics and heroin and the relationship of use/misuse patterns of these drugs to state drug policy initiatives. A secondary data analysis of drug treatment clients (N=52,360) was conducted to project illicit drug use trends in Kentucky. This study describes temporal and geographic trends of self-reported illicit drug use among individuals in state-funded treatment in Kentucky between fiscal year 2010 and fiscal year 2013. Significant reductions in the prevalence of illicit opioid use, declined from fiscal year 2010 to fiscal year 2013 (popioids to heroin (popioid use, but heroin use has increased. One possible explanation for this relationship is that as prescription opioids became more difficult to obtain, users turned to heroin as a substitute. The finding of rising heroin use suggests a need for further policy initiatives to reduce heroin use, but the potential effectiveness of this policy remains unclear. Understanding trends may help to guide future policy efforts and pain management treatment strategies to where they might have their greatest impact. Copyright © 2017 Elsevier B.V.

  7. Developing artemisinin based drug combinations for the treatment of drug resistant falciparum malaria: A review

    2004-01-01

    Full Text Available The emergence and spread of drug resistant malaria represents a considerable challenge to controlling malaria. To date, malaria control has relied heavily on a comparatively small number of chemically related drugs, belonging to either the quinoline or the antifolate groups. Only recently have the artemisinin derivatives been used but mostly in south east Asia. Experience has shown that resistance eventually curtails the life-span of antimalarial drugs. Controlling resistance is key to ensuring that the investment put into developing new antimalarial drugs is not wasted. Current efforts focus on research into new compounds with novel mechanisms of action, and on measures to prevent or delay resistance when drugs are introduced. Drug discovery and development are long, risky and costly ventures. Antimalarial drug development has traditionally been slow but now various private and public institutions are at work to discover and develop new compounds. Today, the antimalarial development pipeline is looking reasonably healthy. Most development relies on the quinoline, antifolate and artemisinin compounds. There is a pressing need to have effective, easy to use, affordable drugs that will last a long time. Drug combinations that have independent modes of action are seen as a way of enhancing efficacy while ensuring mutual protection against resistance. Most research work has focused on the use of artesunate combined with currently used standard drugs, namely, mefloquine, amodiaquine, sulfadoxine/pyrimethamine, and chloroquine. There is clear evidence that combinations improve efficacy without increasing toxicity. However, the absolute cure rates that are achieved by combinations vary widely and depend on the level of resistance of the standard drug. From these studies, further work is underway to produce fixed dose combinations that will be packaged in blister packs. This review will summarise current antimalarial drug developments and outline recent

    The outcome of a 29-day residential addiction treatment programme for persons from Antigua and Barbuda with addiction to drugs or alcohol was assessed. All 100 patients entering the drug and alcohol treatment programme at Crossroads Centre Antigua between November 1998 and October 2002 were included. All patients were assessed with regards to drug or alcohol use or abstinence in November 2002 using telephone and mail follow-up as well as informal follow-up with families and other community contacts. Crossroads Centre Antigua is a 35 bed, 29-day residential treatment centre for drug and alcohol addiction serving patients from developed countries (85%) and from the Caribbean region (15%). Patients records were also reviewed to obtain age, gender, ethnicity, drug of choice, years of problematic use, completion of the 29 day programme, family member participation at Crossroads Centre Antigua (a four-day programme) and acceptance of halfway house placement. Of the 100 Antiguan patients admitted, 46 (46%) were abstinent (non-relapsers) at average 20.7+/-14.7 months after treatment. Abstinence did not have to be continuous. Forty-nine were known to be using drug or alcohol (49%) and five (5%) were lost to follow-up and considered to be using drugs (relapsers). Age (37.5 vs 41.1 years), gender (28% vs 22% female), ethnicity (87% vs 87% Afro-Caribbean), years of harmful use (12.7 vs 12.5 years) did not differ significantly between relapsers and non-relapsers. Crack cocaine use (67% vs 65%) and alcohol use (26% vs 31%) as primary addiction did not differ significantly between relapsers and non-relapsers. Relapsers were significantly less likely to complete the 29- day programme (81% vs 100%, p house placement (4% vs 54%, p house placement.

    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.

  13. Assessing the HIV-1 Epidemic in Brazilian Drug Users: A Molecular Epidemiology Approach.

    Directory of Open Access Journals (Sweden)

    Monick Lindenmeyer Guimarães

    Full Text Available Person who inject illicit substances have an important role in HIV-1 blood and sexual transmission and together with person who uses heavy non-injecting drugs may have less than optimal adherence to anti-retroviral treatment and eventually could transmit resistant HIV variants. Unfortunately, molecular biology data on such key population remain fragmentary in most low and middle-income countries. The aim of the present study was to assess HIV infection rates, evaluate HIV-1 genetic diversity, drug resistance, and to identify HIV transmission clusters in heavy drug users (DUs. For this purpose, DUs were recruited in the context of a Respondent-Driven Sampling (RDS study in different Brazilian cities during 2009. Overall, 2,812 individuals were tested for HIV, and 168 (6% of them were positive, of which 19 (11.3% were classified as recent seroconverters, corresponding to an estimated incidence rate of 1.58%/year (95% CI 0.92-2.43%. Neighbor joining phylogenetic trees from env and pol regions and bootscan analyses were employed to subtype the virus from132 HIV-1-infected individuals. HIV-1 subtype B was prevalent in most of the cities under analysis, followed by BF recombinants (9%-35%. HIV-1 subtype C was the most prevalent in Curitiba (46% and Itajaí (86% and was also detected in Brasília (9% and Campo Grande (20%. Pure HIV-1F infections were detected in Rio de Janeiro (9%, Recife (6%, Salvador (6% and Brasília (9%. Clusters of HIV transmission were assessed by Maximum likelihood analyses and were cross-compared with the RDS network structure. Drug resistance mutations were verified in 12.2% of DUs. Our findings reinforce the importance of the permanent HIV-1 surveillance in distinct Brazilian cities due to viral resistance and increasing subtype heterogeneity all over Brazil, with relevant implications in terms of treatment monitoring, prophylaxis and vaccine development.

  16. Tempol treatment reduces anxiety-like behaviors induced by multiple anxiogenic drugs in rats.

    Directory of Open Access Journals (Sweden)

    Gaurav Patki

    Full Text Available We have published that pharmacological induction of oxidative stress (OS causes anxiety-like behavior in rats. Using animal models, we also have established that psychological stress induces OS and leads to anxiety-like behaviors. All evidence points towards the causal role of OS in anxiety-like behaviors. To fully ascertain the role of OS in anxiety-like behaviors, it is reasonable to test whether the pro-anxiety effects of anxiogenic drugs caffeine or N-methyl-beta-carboline-3-carboxamide (FG-7142 can be mitigated using agents that minimize OS. In this study, osmotic pumps were either filled with antioxidant tempol or saline. The pumps were attached to the catheter leading to the brain cannula and inserted into the subcutaneous pocket in the back pocket of the rat. Continuous i.c.v. infusion of saline or tempol in the lateral ventricle of the brain (4.3 mmol/day was maintained for 1 week. Rats were intraperitoneally injected either with saline or an anxiogenic drug one at a time. Two hours later all groups were subjected to behavioral assessments. Anxiety-like behavior tests (open-field, light-dark and elevated plus maze suggested that tempol prevented anxiogenic drug-induced anxiety-like behavior in rats. Furthermore, anxiogenic drug-induced increase in stress examined via plasma corticosterone and increased oxidative stress levels assessed via plasma 8-isoprostane were prevented with tempol treatment. Protein carbonylation assay also suggested preventive effect of tempol in the prefrontal cortex brain region of rats. Antioxidant protein expression and pro-inflammatory cytokine levels indicate compromised antioxidant defense as well as an imbalance of inflammatory response.

    Full Text Available The paper considers issues of the assessment of the socioeconomic consequences of drug abuse in today’s conditions, which have the following features — the approaching of drug-dealers to legalize the drug market, develop the illegal drug market and their analogs and derivatives by the introduction of modern production technologies and distribution of psychoactive agents. Key tendencies observed in the contemporary world in the field of dynamics of the drug market development, which are reflected in the regions of Russia including the Ural Federal District are revealed. The procedure of assessment of socioeconomic expenses of drug abuse including assessment of drug consumers’ expenses and their surrounding people; and also; maintenance costs of the state bodies supervising drug trafficking; expenses for health care and other social expenses connected to drug use; damage to individuals of drug abuse distribution; expenses of private institutions and establishments; socioeconomic impact of drug abuse distribution. The technique uses a tool allowing to carry out a calculation (a heroin equivalent, i.e. the drugs withdrawn by law enforcement agencies and the subsequent calculation of the corresponding number of consumers of each type of drug. This method is aimed at increasing the accuracy of estimates received. On the basis of results calculated according to offered technique, the shares of socioeconomic expenses of drug abuse concerning the income of the cumulative consolidated budget and a gross regional product of the Ural Federal District are defined.

    2010-09-01

    Cardiovascular and cerebrovascular diseases share many pathophysiological traits, often impact one another and share several risk factors, though not always to the same magnitude. Therefore, it is not surprising that many classes of cardiovascular drugs have demonstrated effectiveness in the primary prevention, acute treatment and secondary prevention of stroke. Important advances have been made since 2007 in the use of antiplatelets, anticoagulants, antihypertensives, antiarrhythmics and statins for the treatment of stroke. This review summarizes selected clinical trials of cardiovascular drugs completed from 2007 to 2010 that generated important evidence supporting the efficacy of these drugs in stroke treatment. Ongoing trials and preclinical research of promising agents and treatment strategies are also discussed.

    Dobrev, Dobromir; Nattel, Stanley

    2010-04-03

    Inadequacies in current therapies for atrial fibrillation have made new drug development crucial. Conventional antiarrhythmic drugs increase the risk of ventricular proarrhythmia. In drug development, the focus has been on favourable multichannel-blocking profiles, atrial-specific ion-channels, and novel non-channel targets (upstream therapy). Molecular modification of the highly effective multichannel blocker, amiodarone, to improve safety and tolerability has produced promising analogues such as dronedarone, although this drug seems less effective than does amiodarone. Vernakalant, an atrial-selective drug with reduced proarrhythmic risk, might be useful for cardioversion in atrial fibrillation. Ranolazine, another atrial-selective agent initially developed as an antianginal, has efficacy for atrial fibrillation and is being tested in prospective clinical trials. So-called upstream therapy with angiotensin-converting enzyme and angiotensin-receptor inhibitors, statins, or omega-3 fatty acids and fish oil that target atrial remodelling could be effective, but need further clinical validation. We focus on the basic and clinical pharmacology of newly emerging antiarrhythmic drugs and non-traditional approaches such as upstream therapy for atrial fibrillation. Copyright 2010 Elsevier Ltd.

    2014-10-01

    Public attitudes about drug addiction and mental illness were compared. A Web-based national survey (N=709) was conducted to compare attitudes about stigma, discrimination, treatment effectiveness, and policy support in regard to drug addiction and mental illness. Respondents held significantly more negative views toward persons with drug addiction. More respondents were unwilling to have a person with drug addiction marry into their family or work closely with them. Respondents were more willing to accept discriminatory practices against persons with drug addiction, more skeptical about the effectiveness of treatments, and more likely to oppose policies aimed at helping them. Drug addiction is often treated as a subcategory of mental illness, and insurance plans group them together under the rubric of "behavioral health." Given starkly different public views about drug addiction and mental illness, advocates may need to adopt differing approaches to reducing stigma and advancing public policy.

    High relapse rate of drug-dependent patients is a serious problem in the current situation. The present article describes how to design and implement virtual reality technology for drug-dependent patients with psychological treatment, with the aim at the addiction withdrawal. The software was developed based on open-source game engine for 2D models. The form of a game simulates the actual style in the day-to-day living environment of drug-dependent patients and the temptation of using drugs. The software helps the patients deal with different scenarios and different event handling, cause their own thinking, and response to the temptation from high-risk environment and from other drug-dependent patients. The function of the software is close to the real life of drug-dependent patients, and has a prospect to become a new treatment to reduce the relapse rate of drug-dependence.

  4. Sex Differences in Behavioral Dyscontrol: Role in Drug Addiction and Novel Treatments.

    Carroll, Marilyn E; Smethells, John R

    2015-01-01

    The purpose of this review is to discuss recent findings related to sex differences in behavioral dyscontrol that lead to drug addiction, and clinical implications for humans are discussed. This review includes research conducted in animals and humans that reveals fundamental aspects of behavioral dyscontrol. The importance of sex differences in aspects of behavioral dyscontrol, such as impulsivity and compulsivity, is discussed as major determinants of drug addiction. Behavioral dyscontrol during adolescence is also an important consideration, as this is the time of onset for drug addiction. These vulnerability factors additively increase drug-abuse vulnerability, and they are integral aspects of addiction that covary and interact with sex differences. Sex differences in treatments for drug addiction are also reviewed in terms of their ability to modify the behavioral dyscontrol that underlies addictive behavior. Customized treatments to reduce behavioral dyscontrol are discussed, such as (1) using natural consequences such as non-drug rewards (e.g., exercise) to maintain abstinence, or using punishment as a consequence for drug use, (2) targeting factors that underlie behavioral dyscontrol, such as impulsivity or anxiety, by repurposing medications to relieve these underlying conditions, and (3) combining two or more novel behavioral or pharmacological treatments to produce additive reductions in drug seeking. Recent published work has indicated that factors contributing to behavioral dyscontrol are an important target for advancing our knowledge on the etiology of drug abuse, intervening with the drug addiction process and developing novel treatments.

    1982-01-01

    One hundred ninety-one hyperprolactinemic patients (78 women and 13 men; 54 with pituitary macroadenoma, 53 with microadenoma, and 84 with idiopathic disease) were treated for 2 to 48 months with one or two of the following prolactin (PRL)-lowering drugs: bromocriptine, metergoline, and lisuride. All of the three drugs used were highly effective in lowering PRL levels and restoring gonadal function both in females and in males in the majority of patients with either idiopathic or tumorous disease. In poorly responsive patients, increasing the drug doses resulted in further PRL lowering for all the three drugs. Mild side effects were frequently encountered with initiation of drug treatment but spontaneously subsided in most cases; severe side effects, necessitating stopping of the treatment, occurred in only 12 instances, but changing of the drug allowed PRL-lowering treatment to be continued in 11 of them.

    Järvinen, Margaretha; Ravn, Signe

    2015-01-01

    This article analyses how young people enrolled in drug addiction treatment in Copenhagen, Denmark, explain their cannabis careers and how they view their possibilities for quitting drug use again. Inspired by Mead and narrative studies of health and illness, the article identifies four different drug use ‘aetiologies’ drawn upon by the interviewees. These cover childhood experiences, self-medication, the influence of friends and cannabis use as a specific lifestyle. A central argument of the article is that these explanations not only concern the past but also point towards the future by assigning the interviewee a more or less agential position in relation to drugs. Further, the drug narratives are viewed as interactional achievements, related to the social context in which they were produced, namely, the institutional setting of the treatment centres. The article is based on 30 qualitative interviews with young people in drug addiction treatment. PMID:25688710

    Background: In 2015 the number of refugees who sought asylum in Germany has increased dramatically. Therefore, the medical care for these refugees faces huge challenges. The treatment of mental illness of refugees is a particular difficult topic. Objective of this study is the acquisition of the outpatient prescriptions of drugs for newly arrived refugees in Erlangen, focused on psychotropic drugs. Methods: Evaluation of all outpatient prescribed drugs (n=1 137), which were prescribed between 10/01/2014 and 09/30/2015 for asylum seekers living in the refugee center in Erlangen, a branch of the "Central Admission Institution" ("ZAE") Zirndorf. Funding organization of this treatment is the City of Erlangen. Settlement documents of the City of Erlangen were used for the analysis. Results: The prescribed drugs cover the spectrum of acute primary care. Big parts of the prescription rates are antiinfectives (ATC-Code: J), medication for the respiratory system (ATC: R), as well as non-steroidal anti-inflammatory drug (NSAID's: ibuprofen, paracetamol, metamizole). The prescription of psychotropic drugs is relatively underrepresented. © Georg Thieme Verlag KG Stuttgart · New York.

    2013-10-01

    The drug treatment of prostate cancer was for many years based on androgen deprivation with luteinizing hormone-releasing hormone (LHRH) analogues.This treatment still represents the standard first line treatment for advanced prostate cancer. In cases of progression to metastatic castration-resistant prostate cancer (mCRPC) further treatment options used to be limited. Only the chemotherapy drug docetaxel could demonstrate a significant overall survival benefit. Within the last few years, however, five new treatments for patients with mCRCP have achieved significant results in large phase III trials. Interestingly they have different mechanisms of action: abiraterone is a testosterone synthesis inhibitor, enzalutamide is a novel antiandrogen, cabazitaxel is a cytotoxic drug, radium-223 is a radionuclide and sipuleucel-T an immunotherapy. Further new drugs are under investigation. The integration of these new treatment options as well as an optimal sequence and combination is the main focus of current research.

    To examine drug treatment in nursing home patients at the end of life, and identify predictors of palliative drug therapy. A historical cohort study. Three urban nursing homes in Norway. All patients admitted from January 2008 and deceased before February 2013. Drug prescriptions, diagnoses, and demographic data were collected from electronic patient records. Palliative end-of-life drug treatment was defined on the basis of indication, drug, and formulation. 524 patients were included, median (range) age at death 86 (19-104) years, 59% women. On the day of death, 99.4% of the study population had active prescriptions; 74.2% had palliative drugs either alone (26.9%) or concomitantly with curative/preventive drugs (47.3%). Palliative drugs were associated with nursing home, length of stay > 16 months (AOR 2.10, 95% CI 1.12-3.94), age (1.03, 1.005-1.05), and a diagnosis of cancer (2.12, 1.19-3.76). Most initiations of palliative drugs and withdrawals of curative/preventive drugs took place on the day of death. Palliative drug therapy and drug therapy changes are common for nursing home patients on the last day of life. Improvements in end-of-life care in nursing homes imply addressing prognostication and earlier response to palliative needs.

    People who inject drugs (PWID) achieve adherence to and outcomes from hepatitis C virus (HCV) treatment comparable to other patients. Nonetheless, this population has been excluded from treatment by regulation or practice. Approval of safer and more effective oral HCV medicines should offer greater treatment options for PWID, although high medicine prices have led to continued treatment rationing and exclusion in developed countries. In middle-income countries (MICS), treatment is largely unavailable and unaffordable for most PWID. Human rights analysis, with its emphasis on the universal and interconnected nature of the economic, social and political spheres, offers a useful framework for HCV treatment reform. Using peer-reviewed and grey literature, as well as community case reports, we discuss barriers to treatment, correlate these barriers to rights violations, and highlight examples of community advocacy to increase treatment for PWID. Structural drivers of lack of treatment access for PWID include stigma in health settings; drug use status as a criterion for treatment exclusion; requirements for fees or registration by name as a drug user prior to treatment initiation; and incarceration/detention in prisons and rehabilitation centers where treatment is unavailable. High medicine prices force further exclusion of PWID, with cost containment masked as concern about treatment adherence. These barriers correlate to multiple rights violations, including of the rights to privacy; non-discrimination; health; freedom of information; fair trial; and freedom from cruel, inhuman and degrading treatment. Needed reforms include decriminalization of drug use, possession of drugs and drug injecting equipment; removal of exclusionary or discriminatory treatment protocols; approaches to strengthen links between health providers and increase participation of PWID in treatment design and implementation; and measures to increase transparency in government/pharmaceutical company

    In this article, I examine children's reported experiences with stimulant drug treatments for attention deficit hyperactivity disorder in light of bioethical arguments about the potential threats of psychotropic drugs to authenticity and moral agency. Drawing on a study that involved over 150 families in the USA and the UK, I show that children are able to report threats to authenticity, but that the majority of children are not concerned with such threats. On balance, children report that stimulants improve their capacity for moral agency, and they associate this capacity with an ability to meet normative expectations. I argue that although under certain conditions stimulant drug treatment may increase the risk of a threat to authenticity, there are ways to minimise this risk and to maximise the benefits of stimulant drug treatment. Medical professionals in particular should help children to flourish with stimulant drug treatments, in good and in bad conditions.

    Drug reprofiling is emerging as an effective paradigm for discovery of cancer treatments. Herein, an antipsychotic drug is immobilised using the Magic Tag ® chemical genomics tool and screened against a T7 bacteriophage displayed library of polypeptides from Drosophila melanogaster, as a whole genome model, to uncover an interaction with a section of 17-β-HSD10, a proposed prostate cancer target. A computational study and enzyme inhibition assay with full length human 17-β-HSD10 identifies risperidone as a drug reprofiling candidate. When formulated with rumenic acid, risperidone slows proliferation of PC3 prostate cancer cells in vitro and retards PC3 prostate cancer tumour growth in vivo in xenografts in mice, presenting an opportunity to reprofile risperidone as a cancer treatment.

    To estimate adherence and response to therapy for chronic hepatitis C virus (HCV) infection among people with a history of injecting drug use. A secondary aim was to identify predictors of HCV treatment response. Prospective cohort recruited between 2009 and 2012. Participants were treated with peg-interferon alfa-2a/ribavirin for 24 (genotypes 2/3, G2/3) or 48 weeks (genotype 1, G1). Six opioid substitution treatment (OST) clinics, two community health centres and one Aboriginal community-controlled health organization providing drug treatment services in New South Wales, Australia. Among 415 people with a history of injecting drug use and chronic HCV assessed by a nurse, 101 were assessed for treatment outcomes (21% female). Study outcomes were treatment adherence and sustained virological response (SVR, undetectable HCV RNA >24 weeks post-treatment). Among 101 treated, 37% (n = 37) had recently injected drugs (past 6 months) and 62% (n = 63) were receiving OST. Adherence ≥ 80% was 86% (n = 87). SVR was 74% (75 of 101), with no difference observed by sex (males: 76%, females: 67%, P = 0.662). In adjusted analysis, age < 35 (versus ≥ 45 years) [adjusted odds ratio (aOR) = 5.06, 95% confidence interval (CI) = 1.47, 17.40] and on-treatment adherence ≥ 80% independently predicted SVR (aOR = 19.41, 95% CI = 3.61, 104.26]. Recent injecting drug use at baseline was not associated with SVR. People with a history of injecting drug use and chronic hepatitis C virus attending opioid substitution treatment and community health clinics can achieve adherence and responses to interferon-based therapy similar to other populations, despite injecting drugs at baseline. Younger age and adherence are predictive of improved response to hepatitis C virus therapy. © 2015 Society for the Study of Addiction.

    Antiretroviral therapy is being rapidly scaled-up in Western Pacific region countries. Prevention and assessment of HIV drug resistance is an essential component of successful global antiretroviral therapy scale-up. We performed a systematic review of public health surveys and HIV drug resistance studies conducted in the low- and middle-income countries in the Western Pacific region. A total of 38 publications assessing HIV drug resistance were reviewed. Studies assessing transmitted drug resistance in recently infected individuals or drug resistance among individuals starting antiretroviral therapy found low rates of HIV drug resistance. Assessments of HIV drug resistance emerging in populations receiving antiretroviral therapy demonstrated variable rates of drug resistance, but suggest an urgent need to support antiretroviral therapy adherence and retention in care, ensure the use of quality assured drugs, and guarantee continuous drug supplies. Additionally, programmatic assessment informed by routine standardized surveillance of transmitted and acquired HIV drug resistance is essential to optimize antiretroviral therapy delivery in the Western Pacific region.

    2010-12-01

    Pharmacogenetics research looks at variations in the human genome and ways in which genetic factors might influence how individuals respond to drugs. The authors review basic principles of pharmacogenetics and cite findings from several gene-phenotype studies to illustrate possible associations between genetic variants, drug-related behaviors, and risk for drug dependence. Some gene variants affect responses to one drug; others, to various drugs. Pharmacogenetics can inform medication development and personalized treatment strategies; challenges lie along the pathway to its general use in clinical practice.

    Full Text Available Background: Adverse cutaneous drug reactions (ACDRs are the most commonly reported adverse drug events. The causative drugs and clinical patterns of ACDRs are different in various populations. This study was conducted to identify the clinical patterns, causative drugs and reasons for drug administration in patients hospitalized due to ACDR. Materials and Methods: This retrospective study was carried out in a referral university hospital, Isfahan, Iran. The medical records of all patients who were hospitalized in the Dermatology Department due to ACDRs were reviewed covering an 8-year period between December 2006 and August 2013. Results: A total number of 282 patients with the mean age of 29.48 ± 21.18 years were hospitalized in this time period, of which 61% were females. The most common clinical patterns regarding the final diagnosis were Stevens-Johnson syndrome (SJS (32%, exanthematous drug eruptions (24.5% and toxic epidermal necrolysis (TEN (11%. Anticonvulsants were the most frequently implicated drug group (51.8% followed by antibiotics (33.7% and analgesics and non-steroidal anti-inflammatory drugs (5.7%. The most common cause of drug administration was seizure (30% and then upper respiratory tract infections (12%. The frequency distribution of clinical types of reactions was different between age groups (P < 0.001. The severe types (SJS, TEN, drug rash with eosinophilia and systemic symptoms and overlap syndrome were more frequent in the patients aged ≤50 years old (55.2% compare to those aged ≤50 years (28% (P = 0.001. Conclusion: The main causative drugs of ACDRs were anticonvulsants and antibiotics. However, the sever types of reactions were more prevalent.

Threatening, aggression and fighting were observed in the sample. The results indicate the need to provide more intensive interventional strategies to control alcohol consumption in this vulnerable segment of population in order to minimize injuries.

  4. Sedative-Hypnotic Drug Withdrawal Syndrome: Recognition And Treatment.

    Science.gov (United States)

    Santos, Cynthia; Olmedo, Ruben E

    2017-03-01

    Sedative-hypnotic drugs include gamma-Aminobutyric acid (GABA)ergic agents such as benzodiazepines, barbiturates, gamma-Hydroxybutyric acid [GHB], gamma-Butyrolactone [GBL], baclofen, and ethanol. Chronic use of these substances can cause tolerance, and abrupt cessation or a reduction in the quantity of the drug can precipitate a life-threatening withdrawal syndrome. Benzodiazepines, phenobarbital, propofol, and other GABA agonists or analogues can effectively control symptoms of withdrawal from GABAergic agents. Managing withdrawal symptoms requires a patient-specific approach that takes into account the physiologic pathways of the particular drugs used as well as the patient's age and comorbidities. Adjunctive therapies include alpha agonists, beta blockers, anticonvulsants, and antipsychotics. Newer pharmacological therapies offer promise in managing withdrawal symptoms.

    The aim of this analysis was to provide an estimate of drug utilization indicators (persistence, switch rate and drug consumption) on biologics and the corresponding costs (drugs, admissions and specialist care) incurred by the Italian National Health Service in the management of adult patients with rheumatoid arthritis (RA). We conducted an observational retrospective cohort analysis using the administrative databases of three local health units. We considered all patients aged ≥18 years with a diagnosis of RA and at least one biologic drug prescription between January 2010 and December 2012 (recruitment period). Persistence was defined as maintenance over the last 3 months of the follow-up period of the same biological therapy administered at the index date. A switch was defined as the presence of a biological therapy other than that administered at the index date during the last 3 months of the follow-up period. Hospital admissions (with a diagnosis of RA or other RA-related diagnoses), specialist outpatient services, instrumental diagnostics and pharmaceutical consumption were assessed. The drug utilization analysis took into account only biologics with at least 90 patients on treatment at baseline (adalimumab n=144, etanercept n=236 and infliximab n=94). In each year, etanercept showed better persistence with initial treatment than adalimumab or infliximab. Etanercept was characterized by the lowest number of patients increasing the initial drug consumption (2.6%) and by the highest number of patients reducing the initial drug consumption (10.5%). The mean cost of treatment for a patient persisting with the initial treatment was €12,388 (€14,182 for adalimumab, €12,103 for etanercept and €11,002 for infliximab). The treatment costs for patients switching from initial treatment during the first year of follow-up were higher than for patients who did not switch (€12,710 vs. €11,332). Persistence, switch rate and drug consumption seem to directly

    This study assessed substance abuse treatment providers' beliefs about empirically supported treatments (ESTs) to determine if providing information about empirical support for interventions would change beliefs. Treatment providers (N=136) completed an interview regarding five interventions with varied empirical support: contingency management (CM), motivational interviewing (MI), relapse prevention (RP), 12-step approaches (TSA), and verbal confrontation (VC). Participants then read primers describing empirical support for each intervention prior to completing a repeat interview. Overall, providers reported positive beliefs about ESTs. Baseline beliefs about empirical support for each intervention were inflated relative to that of expert raters except for CM. After reading the primers, beliefs about efficacy changed in the direction of the experts for all interventions except MI, but continued to be inflated except for CM. Willingness to utilize interventions increased for RP, MI, and CM and decreased for TSA and VC, but remained higher than warranted by empirical support. Copyright 2009.

    The therapeutic efficacy of direct drug infusion into the brain, the target organ of transmissible spongiform encephalopathies, was assessed in transgenic mice intracerebrally infected with 263K scrapie agent. Pentosan polysulfate (PPS) gave the most dramatic prolongation of the incubation period, and amphotericin B had intermediate effects, but antimalarial drugs such as quinacrine gave no significant prolongation. Treatment with the highest dose of PPS at an early or late stage of the infection prolonged the incubation time by 2.4 or 1.7 times that of the control mice, respectively. PPS infusion decreased not only abnormal prion protein deposition but also neurodegenerative changes and infectivity. These alterations were observed within the brain hemisphere fitted with an intraventricular infusion cannula but not within the contralateral hemisphere, even at the terminal disease stage long after the infusion had ended. Therapeutic effects of PPS were also demonstrated in mice infected with either RML agent or Fukuoka-1 agent. However, at doses higher than that providing the maximal effects, intraventricular PPS infusion caused adverse effects such as hematoma formation in the experimental animals. These findings indicate that intraventricular PPS infusion might be useful for the treatment of transmissible spongiform encephalopathies in humans, providing that the therapeutic dosage is carefully evaluated.

    To determine which drug references Utah pharmacists use most frequently. To determine which types of drug information questions are most commonly asked, and whether Utah pharmacists have access to adequate references to respond to these questions. A 19-question survey was created using Qualtrics, LLC (Provo, Utah) software. An electronic survey link was sent to 1,431 pharmacists with a valid e-mail address listed in the Department of Professional Licensing database. Questions focused on available references in the participant's pharmacy, how current the references are, and the participant's use of the references. Surveys were analyzed for participants practicing in either community or hospital pharmacies in the state of Utah. A total of 147 responses were included in the analysis. Approximately 44% of respondents practiced in the community, and 56% practiced in a hospital setting. The most commonly used references by Utah pharmacists are Micromedex, Lexicomp, UpToDate, Clinical Pharmacology, and Drug Facts & Comparisons. Pharmacists in the community frequently receive questions related to adverse drug reactions, drug interactions, and over-the-counter medications. Pharmacists in the hospital frequently receive questions relating to dosage and administration, drug interactions, and adverse drug reactions. About 89% of community pharmacists and 96% of hospital pharmacists feel available references are adequate to answer the questions they receive. Utah pharmacists generally use large reference suites to answer drug information questions. The majority of pharmacists consider the references available to them to be adequate to answer the questions they receive.

    Preclinical reconsolidation research offers the first realistic opportunity to pharmacologically weaken the maladaptive memory structures that support relapse in drug addicts. N-methyl D-aspartate receptor (NMDAR) antagonism is a highly effective means of blocking drug memory reconsolidation. However, no research using this approach exists in human addicts. The objective of this study was to assess the potential and clinical outcomes of blocking the reconsolidation of cue-smoking memories with memantine in quitting smokers. Fifty-nine dependent and motivated to quit smokers were randomised to one of three groups receiving the following: (1) memantine with or (2) without reactivation of associative cue-smoking memories or (3) reactivation with placebo on their target quit day in a double-blind manner. Participants aimed to abstain from smoking for as long as possible. Levels of smoking and FTND score were assessed prior to intervention and up to a year later. Primary outcome was latency to relapse. Subjective craving measures and attentional bias to smoking cues were assessed in-lab. All study groups successfully reduced their smoking up to 3 months. Memantine in combination with smoking memory reactivation did not affect any measure of smoking outcome, reactivity or attention capture to smoking cues. Brief exposure to smoking cues with memantine did not appear to weaken these memory traces. These findings could be due to insufficient reconsolidation blockade by memantine or failure of exposure to smoking stimuli to destabilise smoking memories. Research assessing the treatment potential of reconsolidation blockade in human addicts should focus on identification of tolerable drugs that reliably block reward memory reconsolidation and retrieval procedures that reliably destabilise strongly trained memories.

    As the global community makes progress towards the 90-90-90 targets by 2020, a key challenge is ensuring that antiretroviral drugs for children and adolescents are suitable to the context of resource-limited settings. Drug optimization aims to support the expanded use of more simplified, less toxic drug regimens with high barriers to drug resistance that require minimal clinical monitoring while maintaining therapeutic efficacy. This manuscript summarizes the progress made and outlines further critical steps required to ensure that the right drugs are available to start children and adolescents on treatment and to keep them virologically suppressed. Building upon previous work in drug optimization, several important steps were taken in 2014 to ensure alignment between WHO dosing recommendations and the requirements of regulatory bodies, to accelerate drug development, to reduce intellectual property barriers to generic production of combined formulations and rationalize drug selection in countries. The priority for the future is to improve access to antiretroviral therapy (ART) at the two ends of the paediatric age spectrum--infants and adolescents--where the treatment gap is greatest, and optimize drug sequencing with better use of available medicines for second- and third-line ART. Future efforts in this area will require continuous collaboration and coordination, and the promotion of innovative approaches to accelerate access to new drugs and formulations. While significant progress has been made, additional efforts are needed to ensure that treatment targets are reached by 2020.

  13. Reaching out and reaching up - developing a low cost drug treatment system in Cambodia

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available Abstract Cambodia, confronted by the spread of drug misuse among young people, requested support from international agencies to develop a drug treatment programme in 2000. The initial plan developed by the United Nations Office on Drugs and Crime was to set up a number of conventional drug treatment centres in urban areas. During the planning phase, however, the project was redesigned as a community based outreach programme. Ten Community Counselling Teams have been formed and trained in pilot areas, and within the first year of operation 462 drug and alcohol users contacted. Comprising former drug users, family members affected by drug use and health care staff, they have drug scene credibility, local knowledge and connectivity, and a rudimentary level of medical competence. Crucially, they enjoy the support of village elders, who are involved in the planning and reporting stages. While the Community Counselling Teams with their basic training in addiction counselling are in no position as yet to either provide or refer clients to treatment, they can provide brief interventions, organise self help groups, and most importantly provide an alternative to law enforcement. By taking a development centred approach, with emphasis on community, empowerment and inclusion, it provides a constructive and inclusive alternative to medical approaches and the compulsory drug treatment centres. The paper is based on an evaluation involving interviews with a range of stakeholders and a review of project documents.

  14. Sex differences in behavioral dyscontrol: Role in drug addiction and novel treatments

    Marilyn E. Carroll

    2016-02-01

    Full Text Available The purpose of this review is to discuss recent findings related to sex differences in behavioral dyscontrol that lead to drug addiction, and clinical implications for humans are discussed. This review includes research conducted in animals and humans that reveals fundamental aspects of behavioral dyscontrol. The importance of sex differences in aspects of behavioral dyscontrol, such as impulsivity and compulsivity, are discussed as major determinants of drug addiction. Behavioral dyscontrol during adolescence is also an important consideration, as this is the time of onset for drug addiction. These vulnerability factors additively increase drug abuse vulnerability, and they are integral aspects of addiction that covary and interact with sex differences. Sex differences in treatments for drug addiction are also reviewed in terms of their ability to modify the behavioral dyscontrol that underlies addictive behavior. Customized treatments to reduce behavioral dyscontrol are discussed, such as: 1 using natural consequences such as nondrug rewards (e.g., exercise to maintain abstinence, or using punishment as a consequence for drug use, 2 targeting factors that underlie behavioral dyscontrol, such as impulsivity or anxiety, by repurposing medications to relieve these underlying conditions, and 3 combining two or more novel behavioral or pharmacological treatments to produce additive reductions in drug seeking. Recent published work has indicated that factors contributing to behavioral dyscontrol are an important target for advancing our knowledge on the etiology of drug abuse, intervening with the drug addiction process and developing novel treatments.

    Children and adolescents with mental health problems need effective and safe therapies to support their emotional and social development and to avoid functional impairment and progress of social deficits. Though psychotropic drugs seem to be the preferential treatment, psychotherapy and psychosocial interventions are essential in mental health care. For Germany, current data on the utilization of psychotherapy and psychosocial interventions in children with mental health problems is lacking. To analyse why certain children and adolescents with mental or behavioural disorders do and others do not receive non-drug treatment, we assessed predictors associated with specific non-drug psychiatric/psychotherapeutic treatment including psychosocial interventions, psychotherapy and other non-drug treatments. The study is based on data of two large German health insurance funds, AOK and TK, comprising 30 % of the German child and adolescent population. Predictors of non-drug psychiatric/psychotherapeutic treatment were analysed for 23,795 cases and two controls for every case of the same age and sex in children aged 0-17 years following a new diagnosis of mental or behavioural disorder in 2010. Predictors were divided according to Andersen's behavioural model into predisposing, need and enabling factors. The most prominent and significant predictors positively associated with non-drug psychiatric/psychotherapeutic treatment were the residential region as predisposing factor; specific, both ex- and internalizing, mental and behavioural disorders, psychiatric co-morbidity and psychotropic drug use as need factors; and low area deprivation and high accessibility to outpatient physicians and inpatient institutions with non-drug psychiatric/psychotherapeutic department as enabling factors. In conclusion, the present study suggests that the residential region as proxy for supply of therapist and socioeconomic situation is an influencing factor for the use of psychotherapy. The

    Vagus nerve stimulation (VNS) has been demonstrated to be safe and effective for adults and children with drug-resistant epilepsy and is able to improve most types of epilepsy. The aim of this study, in a paediatric population, was to assess the overall efficacy of vagus nerve stimulation on seizures, to assess tolerability and quality of life. This single-centre, retrospective study reviewed the files of 29 children in whom a vagus nerve stimulator was implanted between 1995 and 2012. The response rate (greater than 50% reduction of the seizure frequency), antiepileptic efficacy according to the type of epilepsy or age at implantation or age at onset of epilepsy, the time-course of seizures, adverse effects, overall quality of life and number of hospitalisations were studied. In our population, vagus nerve stimulation achieved a significant reduction in the seizure frequency throughout follow-up (p = 0.015). Response rates were 59% at 3 months, and 66% at 6 months, and the response rate then remained stable at about 70%. Stimulation tended to be more effective in patients with non-idiopathic partial epilepsy than in patients with non-idiopathic and idiopathic generalised epilepsy (0.01 Vagus nerve stimulation is a safe and effective treatment option in children with drug-resistant epilepsy who are not candidates for surgery.

    Full Text Available As the targeted drugs come into being in recent years, such as monoclonal antibody, great achievements have been made for the treatment of malignant lymphoma (ML. Rituximab, a monoclonal antibody against CD20 whose effective rate is up to 85% in the first-line treatment of lymphoma, has become the standard first-line treatment of multiple B cell lymphomas. However, how to improve the therapeutic efficacy of B lymphoma and reduce reoccurrence rate in drugresistant patients still need to be further studied. And great importance is increasingly attached to the development of new drugs, especially tumor angiogenesis drugs, in which Bevacizumab and Endostatin are studied as the main representative for the treatment of ML. This paper mainly made a review on Current situation and prospects of anti-angiogenesis drugs for the treatment of lymphoma.

    Only a small fraction of drug users worldwide enter treatment each year. We evaluated the efficacy of a systemic family outreach intervention (SFOI) for young, untreated drug users, using a quasi-experimental design in which the experimental group (EG) received SFOI and the control group (CG) received traditional outreach work (OW). Both pre- and post-treatment, we administered the Addiction Severity Index-6 (ASI-6), the Family Environment Scale (FES), and tests of parental practices and risky behavior. Post-treatment, there was a fivefold improvement on the ASI-6 and a significant worsening on the conflict sub-scale of the FES in the EG as compared with the CG. SFOI was more efficacious than OW in reducing drug use in the drug user's home environment. The increased conflict in the EG might be explained by parents' increased awareness of abnormal behaviors and implementation of strategies to protect their children. Copyright © 2013 Elsevier Inc.

    Breath analysis not only holds great potential for the development of new non-invasive diagnostic methods, but also for the identification and follow up of drug levels in breath. This is of interest for both, forensic and medical science. On the one hand, the detection of drugs of abuse in exhaled breath-similar to the well-known breath alcohol tests-would be highly desirable as an alternative to blood or urine analysis in situations such as police controls for drugged driving. The non-invasive detection of drugs and their metabolites is thus of great interest in forensic science, especially since marijuana is becoming legalized in certain parts of the US and the EU. The detection and monitoring of medical drugs in exhaled breath without the need of drawing blood samples on the other hand, is of high relevance in the clinical environment. This could facilitate a more precise medication and enable therapy control without any burden to the patient. Furthermore, it could be a step towards personalized medicine. This review gives an overview of the current state of drug detection in breath, including both volatile and non-volatile substances. The review is divided into two sections. The first section deals with qualitative detection of drugs (drugs of abuse), while the second is related to quantitative drug detection (medical drugs). Chances and limitations are discussed for both aspects. The detection of the intravenous anesthetic propofol is presented as a detailed example that demonstrates the potential, requirements, pitfalls and limitations of therapeutic drug monitoring by means of breath analysis.

    Obesity is a growing epidemic and a major contributor to the global burden of disease. Obesity strains the healthcare systems and has profound economic and psychosocial consequences. Historically, pharmacotherapy for obesity has witnessed the rise and fall of several promising drug candidates that had to be eventually withdrawn due to unacceptable safety concerns. Currently four drugs are approved for chronic weight management in obese adults: orlistat, lorcaserin, phentermine/topiramate extended release and naltrexone/bupropion extended release. While lorcaserin and phentermine/topiramate were approved by US Food and Drug Administration (FDA) in 2012, after a gap of 13 years following the licensing of orlistat, naltrexone/bupropion has been recently approved in 2014. This review provides a brief overview of these current therapeutic interventions available for management of obesity along with the evidence of their safety and efficacy. Additionally, several novel monotherapies as well as combination products are undergoing evaluation in various stages of clinical development. These therapies if proven successful will strengthen the existing armamentarium of antiobesity drugs and will be critical to combat the global public health crisis of obesity and its associated co-morbidities.

    Loyal promotion of the pharmaceutical industry has been challenged by stakeholders. Drug advertising is the easiest point to assess. Based on the agency theory, our objective was to describe the governance of advertising control when it was misleading and the terms of penalties within the framework of the contradictory process between the industry and the regulatory authorities. We conducted a thorough analysis of the contents of the minutes of the Board of Control of advertising from April 2007 to May 2010. The amounts of penalties were analyzed according to three criteria: the timing of the examination procedure (first session versus second session), the nature of the penalty (ban versus notice of change) and the company's defense strategy (written response versus presence of company representatives). Thirty-nine reports involving 62 projects to ban advertisements were analyzed. The first two causes of penalties were off label promotion and non-objective use of study results to support claims. The Committee issued 47 advertising bans (76%) and 15 formal notices of change (24%). When the defense strategy of the company involved the presence of representatives, there was a significant reduction of votes in favor of a ban (68% versus 81%, Pstrategy did not influence the nature of the penalty (Chi(2)=2.05; P=n.s). These results should be put into perspective considering the fact that the qualitative composition of the commission was not free of potential conflicts of interest and that, moreover, only 10% of the penalty projects were reviewed. In addition, advertising control does not address the issue of the loyalty of the sales forces. Finally, our results open perspectives for research and managerial applications for the governance of advertising controls. Copyright © 2013. Published by Elsevier Masson SAS.

  5. Blood pressure reduction, persistence and costs in the evaluation of antihypertensive drug treatment – a review

    2009-03-01

    Full Text Available Abstract Background Blood pressure lowering drugs are usually evaluated in short term trials determining the absolute blood pressure reduction during trough and the duration of the antihypertensive effect after single or multiple dosing. A lack of persistence with treatment has however been shown to be linked to a worse cardiovascular prognosis. This review explores the blood pressure reduction and persistence with treatment of antihypertensive drugs and the cost consequences of poor persistence with pharmaceutical interventions in arterial hypertension. Methods We have searched the literature for data on blood pressure lowering effects of different antihypertensive drug classes and agents, on persistence with treatment, and on related costs. Persistence was measured as patients' medication possession rate. Results are presented in the form of a systematic review. Results Angiotensin II receptor blocker (ARBs have a competitive blood pressure lowering efficacy compared with ACE-inhibitors (ACEi and calcium channel blockers (CCBs, beta-blockers (BBs and diuretics. 8 studies describing the persistence with treatment were identified. Patients were more persistent on ARBs than on ACEi and CCBs, BBs and diuretics. Thus the product of blood pressure lowering and persistence was higher on ARBs than on any other drug class. Although the price per tablet of more recently developed drugs (ACEi, ARBs is higher than that of older ones (diuretics and BBs, the newer drugs result in a more favourable cost to effect ratio when direct drug costs and indirect costs are also considered. Conclusion To evaluate drugs for the treatment of hypertension several key variables including the blood pressure lowering effect, side effects, compliance/persistence with treatment, as well as drug costs and direct and indirect costs of medical care have to be considered. ARBs, while nominally more expensive when drug costs are considered only, provide substantial cost savings

    Full Text Available Background and Aims: The aim of this study was to assess the oral health behaviors in women with addiction history. Materials and Methods: A cross-sectional study was carried out in women drug treatment centers under the supervision of Welfare Organization of Tehran province in Iran. Data collection process was conducted in three centers including a questionnaire with an interview format, clinical examination, and Chi-Square test and MANOVA for statistical analysis. Results: The mean age of 95 women participating in this study was less than forty, whereas the age of starting drugs was twenty two. A majority of the patients were unemployed (71% and more than that of two-third did not have a diploma education. Almost half of dentate participants had never or rarely brushed their teeth. Most of them had never used dental floss, while more than half had three or more times snacks or sweet drinks and more than three-fourth were daily smokers. The MANOVA analysis showed that the type of clinic to be visited, age, used stimulant, drug dependency length, the last time a dentist being visited and the brushing period had a statistically significant relationship with Decayed Teeth (DT, Missing Teeth (MT and Filled Teeth (FT (P<0.05. Conclusion: Women with the prior drug addiction history had an unpromising oral health status which was obvious in their self-perceived oral health. Taking the appropriate preventive and therapeutic actions aiming for promoting oral health status of them seems to be necessary.

    Directory of Open Access Journals (Sweden)

    Monika Szpringer

    2015-03-01

    Full Text Available Introduction: During the last few years there has been a considerable value growth in the demand for the so-called over-the-counter drugs (OTC, available without doctor’s prescription. Using OTC drugs is related to self-treatment, aimed at mitigating first symptoms of a cold, flu, or various types of pain. The omnipresent advertisements for OTC drugs encourage and contribute to the elevated demand. Unfortunately, the marketing techniques used in advertisements fail to provide reliable and objective information to the viewers about specific products. Aim of the research: To determine the respondents’ opinions on using OTC drugs and to assess how advertisements influence the consumers’ needs. Material and methods : The study was conducted by means of a diagnostic survey using a questionnaire. For the purpose of the study, the authors prepared a survey questionnaire, which was used as a research tool. The study included 114 respondents, falling within an age bracket of 18–66 years. Results : The most frequently used OTC drugs were painkillers and medicines for cold and flu symptoms (68.33% of women and 59.09% of men. The drugs were usually bought in pharmacies and grocery/convenience stores. Conclusions: Taking OTC drugs is a widespread phenomenon, both in women and men. The obtained results clearly indicate that advertisements have a considerable impact upon target groups and contribute to increased consumption of OTC drugs.

  9. Quantifying the effects of antiangiogenic and chemotherapy drug combinations on drug delivery and treatment efficacy

    Tumor-induced angiogenesis leads to the development of leaky tumor vessels devoid of structural and morphological integrity. Due to angiogenesis, elevated interstitial fluid pressure (IFP) and low blood perfusion emerge as common properties of the tumor microenvironment that act as barriers for drug delivery. In order to overcome these barriers, normalization of vasculature is considered to be a viable option. However, insight is needed into the phenomenon of normalization and in which conditions it can realize its promise. In order to explore the effect of microenvironmental conditions and drug scheduling on normalization benefit, we build a mathematical model that incorporates tumor growth, angiogenesis and IFP. We administer various theoretical combinations of antiangiogenic agents and cytotoxic nanoparticles through heterogeneous vasculature that displays a similar morphology to tumor vasculature. We observe differences in drug extravasation that depend on the scheduling of combined therapy; for concurrent therapy, total drug extravasation is increased but in adjuvant therapy, drugs can penetrate into deeper regions of tumor.

    Full Text Available Plasma technology has been widely used to increase the surface energy of the polymer surfaces for many industrial applications; in particular to increase in wettability. The present work was carried out to investigate how surface modification using plasma treatment modifies the surface energy of micro-injection moulded microneedles and its influence on drug delivery. Microneedles of polyether ether ketone and polycarbonate and have been manufactured using micro-injection moulding and samples from each production batch have been subsequently subjected to a range of plasma treatment. These samples were coated with bovine serum albumin to study the protein adsorption on these treated polymer surfaces. Sample surfaces structures, before and after treatment, were studied using atomic force microscope and surface energies have been obtained using contact angle measurement and calculated using the Owens-Wendt theory. Adsorption performance of bovine serum albumin and release kinetics for each sample set was assessed using a Franz diffusion cell. Results indicate that plasma treatment significantly increases the surface energy and roughness of the microneedles resulting in better adsorption and release of BSA.

  11. Novel metabolic drugs and blood pressure: implications for the treatment of obese hypertensive patients?

    Engeli, Stefan; Jordan, Jens

    2013-10-01

    Hypertension and obesity often coexist, exposing patients to cardiovascular and metabolic risks, particularly type 2 diabetes mellitus. Moreover, obesity may render hypertensive patients treatment resistant. We review how drugs recently approved for obesity or type 2 diabetes mellitus treatment affect blood pressure. The weight-reducing drug lorcaserin induces modest reductions in body weight while slightly improving blood pressure. The fixed low-dose topiramate/phentermine combinations elicit larger reductions in body weight and blood pressure. Concomitant improvements in glucose metabolism, adiposity, and blood pressure differentiate the first clinically available SGLT2 inhibitor dapagliflozin from other oral antidiabetic drugs. Yet, the mechanisms through which metabolic drugs affect blood pressure and their interaction with antihypertensive drugs are poorly understood. Blood pressure-lowering effects of metabolic drugs could be exploited in the clinical management of obese hypertensive patients with and without type 2 diabetes mellitus, particularly in patients with difficult to control arterial hypertension.

  12. Stories of change in drug treatment: a narrative analysis of 'whats' and 'hows' in institutional storytelling.

    2015-06-01

    Addiction research has demonstrated how recovering individuals need narratives that make sense of past drug use and enable constructions of future, non-addict identities. However, there has not been much investigation into how these recovery narratives actually develop moment-to-moment in drug treatment. Building on the sociology of storytelling and ethnographic fieldwork conducted at two drug treatment institutions for young people in Denmark, this article argues that studying stories in the context of their telling brings forth novel insights. Through a narrative analysis of both 'the whats' (story content) and 'the hows' (storying process) the article presents four findings: (1) stories of change function locally as an institutional requirement; (2) professional drug treatment providers edit young people's storytelling through different techniques; (3) the narrative environment of the drug treatment institution shapes how particular stories make sense of the past, present and future; and (4) storytelling in drug treatment is an interactive achievement. A fine-grained analysis illuminates in particular how some stories on gender and drug use are silenced, while others are encouraged. The demonstration of how local narrative environments shape stories contributes to the general understanding of interactive storytelling in encounters between professionals and clients in treatment settings. © 2015 The Author.

    There has been a limited focus on prescription drug abuse among women in the country. Choice of psychoactive substance, reasons for initiation and co-occurring disorders have been found to be different among men and women. The current study was aimed at studying the profile of female patients seeking in-patient treatment for prescription drug use over a period of five years at a tertiary care drug dependence treatment centre in India. Case records of all female patients admitted with substance use disorder at a national level drug dependence treatment centre in north India across five years (between January 2008 and December 2012) were reviewed retrospectively to study their socio-demographic and clinical profile. The information was gathered using a semi-structured proforma and detailed case records. Abstinence, relapse and retention rates were calculated. Over the five years, 31 female patients were admitted with prescription drug abuse. Of them, 12 (39%) used prescription opioids and 11 (36%) used prescription opioid along with benzodiazepines. Commonest prescription opioid was pentazocine used by 87 per cent of the women. Twenty two (71%) women were introduced to opioid by medical practitioners and commonest reason for introduction was pain (among 48%). Common co-occurring psychiatric diagnoses were depressive disorder (26%), cluster B traits/disorder (19%) and somatoform disorder (13%). Eight women did not complete treatment and left against medical advice. Thirteen women were advised maintenance treatment, and 70 per cent of them were retained for at least six months. Our findings revealed a link between mental illness, pain and non-medical use of prescription opioids among women. Majority of these women received opioids as a legitimate prescription form physician. Therefore, these legitimate prescribers should be trained for pain management to facilitate proper treatment of pain and to prevent the subsequent misuse of these medicines. Female patients with

    Psychoactive substance use can cause a broad variety of mental health disorders and social health problems for the drug users, their family and society. The Ministry of Health, Treatment, and Medical Education of Iran has recently proclaimed an estimated number of 2 million drug abusers and 200,000 injecting drug users (IDUs). For data collection, the directory of mental, social health, and Addiction designed a questionnaire in cooperation with Drug Control Headquarters of Iran. Among 402 IDUs patients, a large amount of them were male, single, and younger than 39 years. Regarding psychotic and somatic symptoms caused by methadone therapy, most of the participants had no problem with methadone maintenance treatment (MMT). There is a need to train health staff, and the community, concerning preventive measures, treatment, and reducing harm for substance drug users.

    Full Text Available The efficacy of antiretroviral drugs is limited by the development of drug resistance. Therefore, it is important to examine HIV drug resistance following the nationwide implementation of drug resistance testing in China since 2009. We conducted drug resistance testing in patients who were already on or new to HIV antiretroviral therapy (ART in Shandong Province, China, from 2011 to 2013, and grouped them based on the presence or absence of drug resistance to determine the effects of age, gender, ethnicity, marital status, educational level, route of transmission and treatment status on drug resistance. We then examined levels of drug resistance the following year. The drug resistance rates of HIV patients on ART in Shandong from 2011 to 2013 were 3.45% (21/608, 3.38% (31/916, and 4.29% (54/1259, per year, respectively. M184V was the most frequently found point mutation, conferring resistance to the nucleoside reverse transcriptase inhibitor, while Y181C, G190A, K103N and V179D/E/F were the most frequent point mutations conferring resistance to the non-nucleoside reverse transcriptase inhibitor. In addition, the protease inhibitor drug resistance mutations I54V and V82A were identified for the first time in Shandong Province. Primary resistance accounts for 20% of the impact factors for drug resistance. Furthermore, it was found that educational level and treatment regimen were high-risk factors for drug resistance in 2011 (P<0.05, while treatment regimen was a high risk factor for drug resistance in 2012 and 2013 (P<0.05. Among the 106 drug-resistant patients, 77 received immediate adjustment of treatment regimen following testing, and 69 (89.6% showed a reduction in drug resistance the following year. HIV drug resistance has a low prevalence in Shandong Province. However, patients on second line ART regimens and those with low educational level need continuous monitoring. Active drug resistance testing can effectively prevent the development

    Acquired drug resistance is the greatest obstacle to the successful treatment of multiple myeloma (MM). Despite recent advanced treatment options such as liposomal formulations, proteasome inhibitors, immunomodulatory drugs, myeloma-targeted antibodies, and histone deacetylase inhibitors, MM is still considered an incurable disease. We investigated whether the clinical exportin 1 (XPO1) inhibitor selinexor (KPT-330), when combined with pegylated liposomal doxorubicin (PLD) or doxorubicin hydrochloride, could overcome acquired drug resistance in multidrug-resistant human MM xenograft tumors, four different multidrug-resistant MM cell lines, or ex vivo MM biopsies from relapsed/refractory patients. Mechanistic studies were performed to assess co-localization of topoisomerase II alpha (TOP2A), DNA damage, and siRNA knockdown of drug targets. Selinexor was found to restore sensitivity of multidrug-resistant 8226B25, 8226Dox6, 8226Dox40, and U266PSR human MM cells to doxorubicin to levels found in parental myeloma cell lines. NOD/SCID-γ mice challenged with drug-resistant or parental U266 human MM and treated with selinexor/PLD had significantly decreased tumor growth and increased survival with minimal toxicity. Selinexor/doxorubicin treatment selectively induced apoptosis in CD138/light-chain-positive MM cells without affecting non-myeloma cells in ex vivo-treated bone marrow aspirates from newly diagnosed or relapsed/refractory MM patients. Selinexor inhibited XPO1-TOP2A protein complexes (proximity ligation assay), preventing nuclear export of TOP2A in both parental and multidrug-resistant MM cell lines. Selinexor/doxorubicin treatment significantly increased DNA damage (comet assay/γ-H2AX) in both parental and drug-resistant MM cells. TOP2A knockdown reversed both the anti-tumor effect and significantly reduced DNA damage induced by selinexor/doxorubicin treatment. The combination of an XPO1 inhibitor and liposomal doxorubicin was highly effective against

The present study examined temporal associations between poly-drug use (i.e. heroin, cannabis, tranquilizers, and amphetamines) and mental distress over a 10-year period. A clinical cohort of 481 patients was recruited from substance use treatment facilities in Norway, and prospectively interviewed 1, 2, 7 and 10years after the initial data collection at treatment admission. At each assessment participants completed a questionnaire addressing their substance use and mental distress. Longitudinal growth models were used to examine whether, and if so, how, levels of drug use were associated with the level and rate of change in mental distress over time. Results from the longitudinal growth models showed a co-occurrence between active poly-drug use and mental distress, such that there was a dose-response effect where mental distress increased both in magnitude and over time with the number of drugs used. Reduction in mental distress during the 10-year study period was evident only in the no-drug use condition. Use of multiple drugs and mental distress appear strongly co-related over time. Pre-treatment assessment should carefully identify individuals manifesting poly-drug use and mental disorders. Treatment and follow-up services should be tailored to their specific needs.

  3. Altered network communication following a neuroprotective drug treatment.

    Directory of Open Access Journals (Sweden)

    Kathleen Vincent

    Full Text Available Preconditioning is defined as a range of stimuli that allow cells to withstand subsequent anaerobic and other deleterious conditions. While cell protection under preconditioning is well established, this paper investigates the influence of neuroprotective preconditioning drugs, 4-aminopyridine and bicuculline (4-AP/bic, on synaptic communication across a broad network of in vitro rat cortical neurons. Using a permutation test, we evaluated cross-correlations of extracellular spiking activity across all pairs of recording electrodes on a 64-channel multielectrode array. The resulting functional connectivity maps were analyzed in terms of their graph-theoretic properties. A small-world effect was found, characterized by a functional network with high clustering coefficient and short average path length. Twenty-four hours after exposure to 4-AP/bic, small-world properties were comparable to control cultures that were not treated with the drug. Four hours following drug washout, however, the density of functional connections increased, while path length decreased and clustering coefficient increased. These alterations in functional connectivity were maintained at four days post-washout, suggesting that 4-AP/bic preconditioning leads to long-term effects on functional networks of cortical neurons. Because of their influence on communication efficiency in neuronal networks, alterations in small-world properties hold implications for information processing in brain systems. The observed relationship between density, path length, and clustering coefficient is captured by a phenomenological model where connections are added randomly within a spatially-embedded network. Taken together, results provide information regarding functional consequences of drug therapies that are overlooked in traditional viability studies and present the first investigation of functional networks under neuroprotective preconditioning.

    Full Text Available Objective: To determine which drug references Utah pharmacists use most frequently. To determine which types of drug information questions are most commonly asked, and whether Utah pharmacists have access to adequate references to respond to these questions. Methods: A 19-question survey was created using Qualtrics, LLC (Provo, Utah software. An electronic survey link was sent to 1,431 pharmacists with a valid e-mail address listed in the Department of Professional Licensing database. Questions focused on available references in the participant’s pharmacy, how current the references are, and the participant’s use of the references. Surveys were analyzed for participants practicing in either community or hospital pharmacies in the state of Utah. Results: A total of 147 responses were included in the analysis. Approximately 44% of respondents practiced in the community, and 56% practiced in a hospital setting. The most commonly used references by Utah pharmacists are Micromedex, Lexicomp, UpToDate, Clinical Pharmacology, and Drug Facts & Comparisons. Pharmacists in the community frequently receive questions related to adverse drug reactions, drug interactions, and over-the-counter medications. Pharmacists in the hospital frequently receive questions relating to dosage and administration, drug interactions, and adverse drug reactions. About 89% of community pharmacists and 96% of hospital pharmacists feel available references are adequate to answer the questions they receive. Conclusions: Utah pharmacists generally use large reference suites to answer drug information questions. The majority of pharmacists consider the references available to them to be adequate to answer the questions they receive.

    The pharmacological management of motor and non-motor symptoms of Parkinson’s disease (PD) is the central theme of this thesis. In a literature study, we revealed that relatively few efforts have been made to investigate the role of pharmacogenetics in the response to anti-PD drugs and that only few replication studies have been performed. Some interesting associations between genetic variants and anti-PD drug response have been found, but these were conflicting. We concluded that pharmacogen...

  8. An update on drugs for the treatment of menopausal symptoms.

    2015-01-01

    Vasomotor symptoms (VMS) and the genitourinary syndrome of menopause (GSM) are recognized as the most frequent and bothersome symptoms associated with menopause. There are different treatments for both groups of symptoms, being necessary to individualize them. There are different therapies for VMS including hormonal treatments with estrogen, with and without progestins; the new alternative, tissue-selective estrogen complex (TSEC), tibolone, phytoestrogens and only progestins. Evidence also shows efficacy with selective serotonin reuptake inhibitors. Other nonhormonal alternatives exist as second-line treatments, all with not conclusive results. The GSM can be treated with nonhormonal treatments such as vaginal lubricants and moisturizers, other alternatives as vaginal laser needs to have more evidence. On the other hand, there is the possibility to use the hormonal treatments with systemic or local estrogen, which are the most effective treatment, the TSEC and the newest selective estrogen receptor modulator (SERM), ospemifene. Therapies with testosterone and dehydroepiandrosterone (DHEA) are still under study. The GSM can be treated with nonhormonal treatments such as vaginal lubricants and moisturizers, and other alternatives as vaginal laser need to have more evidence. On the other hand, there is the possibility to use the hormonal treatments with systemic or local estrogen, which are the most effective treatment, the TSEC and the newest SERM, ospemifene. Therapies with testosterone and DHEA are still under study. The increasing numbers of therapies for menopausal symptoms open up new options, but we must individualize treatments. New possibilities arise in patients who did not have them and which can improve compliance and is also important to design strategies using combined or sequential treatments.

    2016-08-01

    Current treatment methods for melanoma have some limitations such as less target-specific action, severe side effects and resistance to drugs. Significant progress has been made in exploring novel drug delivery systems based on suitable biochemical mechanisms using nanoparticles ranging from 10 to 400 nm for drug delivery and imaging, utilizing their enhanced penetration and retention properties. Poly-lactide-co-glycolide (PLGA), a copolymer of poly-lactic acid and poly-glycolic acid, provides an ideally suited performance-based design for better penetration into skin cells, thereby having a greater potential for the treatment of melanoma. Moreover, encapsulation protects the drug from deactivation by biological reactions and interactions with biomolecules, ensuring successful delivery and bioavailability for effective treatment. Controlled and sustained delivery of drugs across the skin barrier that otherwise prohibits entry of larger molecules can be successfully made with adequately stable biocompatible nanocarriers such as PLGA for taking drugs through the small cutaneous pores permitting targeted deposition and prolonged drug action. PLGA is now being extensively used in photodynamic therapy and targeted therapy through modulation of signal proteins and drug-DNA interactions. Recent advances made on these nanomedicines and their advantages in the treatment of skin melanoma are highlighted and discussed in this review.

    Health Technology Assessment (HTA) is a multidisciplinary health political instrument that evaluates the consequences, mainly clinical and economical, of a health care technology; the HTA aim is to produce and spread information on scientific and technological innovation for health political decision making process. Drug delivery systems (DDS), such as nanocarriers, are technologically complex but they have pivotal relevance in therapeutic innovation. The HTA process, as commonly applied to conventional drug evaluation, should upgrade to a full pharmaceutical assessment, considering the DDS complexity. This is useful to study more in depth the clinical outcome and to broaden its critical assessment toward pharmaceutical issues affecting the patient and not measured by the current clinical evidence approach. We draw out the expertise necessary to perform the pharmaceutical assessment and we propose a format to evaluate the DDS technological topics such as formulation and mechanism of action, physicochemical characteristics, manufacturing process. We integrated the above-mentioned three points in the Evidence Based Medicine approach, which is data source for any HTA process. In this regard, the introduction of a Pharmaceutics Expert figure in the HTA could be fundamental to grant a more detailed evaluation of medicine product characteristics and performances and to help optimizing DDS features to overcome R&D drawbacks. Some aspects of product development, such as manufacturing processes, should be part of the HTA as innovative manufacturing processes allow new products to reach more effectively patient bedside. HTA so upgraded may encourage resource allocating payers to invest in innovative technologies and providers to focus on innovative material properties and manufacturing processes, thus contributing to bring more medicines in therapy in a sustainable manner.

    The liver is an important target for drug-induced toxicities. Early detection of hepatotoxic drugs requires use of well-characterized test systems, yet current knowledge, gaps and limitations of tests employed remains an important issue for drug development. Areas Covered: The current state of the science, understanding and application of test systems in use for the detection of drug-induced cytotoxicity, mitochondrial toxicity, cholestasis and inflammation is summarized. The test systems highlighted herein cover mostly in vitro and some in vivo models and endpoint measurements used in the assessment of small molecule toxic liabilities. Opportunities for research efforts in areas necessitating the development of specific tests and improved mechanistic understanding are highlighted. Expert Opinion: Use of in vitro test systems for safety optimization will remain a core activity in drug discovery. Substantial inroads have been made with a number of assays established for human Drug-induced Liver Injury. There nevertheless remain significant gaps with a need for improved in vitro tools and novel tests to address specific mechanisms of human Drug-Induced Liver Injury. Progress in these areas will necessitate not only models fit for application, but also mechanistic understanding of how chemical insult on the liver occurs in order to identify translational and quantifiable readouts for decision-making.

    Multidrug-resistant tuberculosis (MDR-TB) is the main indicator of previous treatment in tuberculosis (TB) patients. MDR-TB among treatment-naïve patients indicates infection with drug-resistant Mycobacterium tuberculosis strains, and such cases are considered primary drug-resistant cases. To estimate the prevalence of drug resistance in pulmonary TB (PTB) treatment-naïve patients and to identify the socio-demographic and clinical characteristics of the resistant population. A total of 205 treatment-naïve PTB patients from Manaus, Amazonas State, Brazil, were enrolled. Drug susceptibility testing (DST) was performed on all positive mycobacterial cultures using the 1% proportion method. Positive M. tuberculosis cultures were obtained from only 175 patients for DST. The prevalence of primary MDR-TB was 1.7% (3/175); 14.3% (25/175) of the cultures presented resistance to at least one of the drugs. Resistance to streptomycin, isoniazid, rifampicin and ethambutol was respectively 8.6%, 6.9%, 3.4% and 2.3%. An association between TB patients with resistance to more than one drug and known previous household contact with a TB patient was observed (P= 0.008, OR 6.7, 95%CI 1.2-67.3). Although the prevalence of primary MDR-TB currently is relatively low, it may become a major public health problem if tailored treatment is not provided, as resistance to more than one drug is significantly associated with household contact.

    Differential attrition by minority participants can be as limiting to interpreting final results as poor initial recruitment of minority participants. This is especially important in drug abuse treatment studies, as minorities are over-represented in substance abuse clinical treatment programs. The specific aims of this secondary data analysis were to: (1) determine if there are differences in study retention rates by race/ethnicity and age, and (2) explore other client characteristics, as well as protocol and treatment program factors, that could account for differential retention rates. We conducted a secondary analysis using data from 1737 participants in the first six clinical trials whose databases were locked in the NIDA Clinical Trials Network. Protocol level characteristics were also abstracted from these studies, and we used data from a study which assessed characteristics of community treatment programs that participated in these studies. Logistic regression was used to study the effect on retention of: client, protocol, and program characteristics. In the model of client characteristics, a significant age by race/ethnicity interaction term was detected based on a threshold of 0.1, with younger African Americans having the lowest odds of retention. Primary drug of abuse was also a significant factor in determining study retention, with heroin, methadone, and opiate users having the greatest odds of retention and polydrug users the lowest. Similar analyses testing treatment program characteristics found that only the presence of HIV risk screening and decreasing levels of female admissions (as a percent of total admissions) were related to study retention. In our final model, there was an effect of age, but not race/ethnicity, with younger participants having lower odds of retention. A multivariable model including protocol variables could not be developed due to the high correlation among protocol variables. We excluded those of multi-race/ethnicity and

    Drug dependence is a recognized medical condition and therefore, right to health applies in the same way to drug dependence as it does to any other health condition. The human rights in patient care framework - which refers to the application of basic human rights principles in the delivery of health care services - was used to explore the experiences of equality in the dignity and rights protected by Polish law within four different specialist drug treatment settings in Poland. The views of patients and staff were examined and compared. Focus group interviews were conducted in 12 drug treatment facilities: three inpatient therapeutic communities, three outpatient programs, three opioid substitution programs and three harm reduction programs (drop-in/needle exchange/support). Interviews were conducted with a total of 43 staff and 73 patients. All interviews were audio-recorded with participants' prior consent and transcribed verbatim. Data were analysed according to the problem-centred interview methodology, using CAQDA. Patients described instances of abuse of their rights regarding dignity, privacy, confidentiality, personalized treatment, and respect of patient's time, right to information and to complain. Those accounts were complemented by the perspective of professionals working in drug treatment. Patients of Polish opioid substitution programs reported experiencing more humiliation and disenfranchisement than patients in other drug treatment settings. Drug testing and control, fuelled by prejudices of health professionals, are leading to discriminatory practices in substitution treatment and damaging the chances of therapeutic success. The concept of epistemic injustice illuminates the reasons behind discrimination against patients on opioid substitution programs, who are seen as continuously sick and their illness perceived as a mark of moral, social and epistemic failure.

  9. Prisoners’ experiences of drug treatment and punishment in four Nordic countries

    Directory of Open Access Journals (Sweden)

    Giertsen Hedda

    2015-04-01

    Full Text Available AIMS - This article describes and analyses prisoners’ experiences of drug treatment in prison in four Nordic countries: Denmark, Finland, Norway and Sweden. The article examines how prisoners experience drug treatment, control and sanctions as related to three main topics, namely motivation; the content of the measure and relations to staff; and control and sanctions. METHODS & DATA - The article is based on data from twelve prisons, three in each of the four countries; 91 interviews with prisoners; and around six months of observation. The two main kinds of drug treatment measures are drug treatment units and day programmes. RESULTS - Prisoners described several motives to participate in drug treatment measures: to leave drugs and crime; to renew relations with family and friends; to solve health problems; and to improve their prison conditions. Prisoners found that drug treatment measures offered possibilities to acquire new ways of being. Staff behaviour seemed to be more important to prisoners than the methods used, and some prisoners seemed more positive to staff involved with the drug treatment than to other staff. A surprising finding was the prisoners’ limited critique of controls and sanctions. We see this as embedded in the situation of being a prisoner, and also in relation to contexts outside prison. CONCLUSION - In discussing their experiences in the treatment units, prisoners are not so concerned about the rehabilitative features or the controls and sanctions. They evaluate their present situation in light of a future, which is their real concern. This is in line with a main task for staff, which is to prepare prisoners for release.

    Early imaging or blood biomarkers of tumor response is needed to customize anti-tumor therapy on an individual basis. This study evaluates the sensitivity and relevance of five potential MRI biomarkers. Sixty nude rats were implanted with human glioma cells (U-87 MG) and randomized into three groups: one group received an anti-angiogenic treatment (Sorafenib), a second a cytotoxic drug [1,3-bis(2-chloroethyl)-1-nitrosourea, BCNU (Carmustine)] and a third no treatment. The tumor volume, apparent diffusion coefficient (ADC) of water, blood volume fraction (BVf), microvessel diameter (vessel size index, VSI) and vessel wall integrity (contrast enhancement, CE) were monitored before and during treatment. Sorafenib reduced tumor CE as early as 1 day after treatment onset. By 4 days after treatment onset, tumor BVf was reduced and tumor VSI was increased. By 14 days after treatment onset, ADC was increased and the tumor growth rate was reduced. With BCNU, ADC was increased and the tumor growth rate was reduced 14 days after treatment onset. Thus, the estimated MRI parameters were sensitive to treatment at different times after treatment onset and in a treatment-dependent manner. This study suggests that multiparametric MR monitoring could allow the assessment of new anti-tumor drugs and the optimization of combined therapies. Copyright © 2010 John Wiley & Sons, Ltd.

    Urine source separation has the potential to reduce pharmaceutical loading to the environment, while enhancing nutrient recovery. The focus of this life cycle assessment (LCA) was to evaluate the environmental impacts and economic costs to manage nonsteroidal anti-inflammatory drugs (NSAIDs) (i.e., diclofenac, ibuprofen, ketoprofen and naproxen) and nutrients in human urine. Urine source separation was compared with centralized wastewater treatment (WWT) (biological or upgraded with ozonation). The current treatment method (i.e., centralized biological WWT) was compared with hypothetical treatment scenarios (i.e., centralized biological WWT upgraded with ozonation, and urine source separation). Alternative urine source separation scenarios included varying collection and handling methods (i.e., collection by vacuum truck, vacuum sewer, or decentralized treatment), pharmaceuticals removal by ion-exchange, and struvite precipitation. Urine source separation scenarios had 90% lower environmental impact (based on the TRACI impact assessment method) compared with the centralized wastewater scenarios due to reduced potable water production for flush water, reduced electricity use at the wastewater treatment plant, and nutrient offsets from struvite precipitation. Despite the greatest reduction of pharmaceutical toxicity, centralized treatment upgraded with ozone had the greatest ecotoxicity impacts due to ozonation operation and infrastructure. Among urine source separation scenarios, decentralized treatment of urine and centralized treatment of urine collected by vacuum truck had negligible cost differences compared with centralized wastewater treatment. Centralized treatment of urine collected by vacuum sewer and centralized treatment with ozone cost 30% more compared with conventional wastewater treatment. Copyright © 2016 Elsevier Ltd.

    Drug-resistant epilepsy (DRE) is a top-priority social health problem which requires early individual treatment due to its dramatic repercussions for the patient and society. The International League Against Epilepsy (ILAE) has recently defined DRE as that in which the seizures are not controlled after having correctly taken two appropriate and well tolerated anti-epileptic drugs, with lack of control being understood as the appearance of seizures within one year or in a period less than three times the inter-seizure interval before starting treatment. This International Society recommends a rapid and detailed assessment of all patients in an Epilepsy Unit. A Clinical Epilepsy Unit (CEU) is understood as a group of professionals who, acting in collaboration, have the diagnosis and treatment of the patient with epilepsy as their primary objective. CEUs in Spain may be stratified into different levels depending on the activity carried out in each of them. The specific epilepsy clinic is considered the fundamental type of CEU and includes the necessary figure of an expert in epilepsy. Prolonged video-monitoring is performed in medical CEUs. In medical-surgical CEUs epilepsy surgery with varying degrees of difficulty is also performed. All CEUs must cooperate with consensus protocols, and there must be a two-way flow between them. Stratification of CEUs increases efficacy and efficiency, due to there being a sufficient number of them to ensure easy access by all patients with epilepsy. © 2011 Sociedad Española de Neurología.

    The emerging field of nanotechnology meets the demands for innovative approaches in the diagnosis and treatment of cancer. The nanoparticles are biocompatible and biodegradable and are made of a core, a particle that acts as a carrier, and one or more functional groups on the core which target specific sites. Nanotech in drug delivery includes nanodisks, High Density Lipoprotein nanostructures, liposomes, and gold nanoparticles. The fundamental advantages of nanoparticles are: improved delivery of water-insoluble drugs, targeted delivery, co-delivery of two or more drugs for combination therapy, and visualization of the drug delivery site by combining imaging system and a therapeutic drug. One of the potential applications of nanotechnology is in the treatment of cancer. Conventional methods for cancer treatments have included chemotherapy, surgery, or radiation. Early recognition and treatment of cancer with these approaches is still challenging. Innovative technologies are needed to overcome multidrug resistance, and increase drug localization and efficacy. Application of nanotechnology to cancer biology has brought in a new hope for developing treatment strategies on cancer. In this study, we present a review on the recent advances in nanotechnology-based approaches in cancer treatment. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    2017-10-01

    Implantable cardioverter defibrillators (ICDs) reduce the mortality risk associated with recurrent ventricular tachycardia (VT) and can frequently terminate VT episodes painlessly, but do not prevent recurrent episodes. For patients with symptomatic recurrences, frequent asymptomatic recurrences, ICD shocks, or VT storm, most clinicians recommend strategies to suppress VT. The proarrhythmic mortality risk of antiarrhythmic drugs (AADs) may be mitigated by the presence of an ICD, but these medications are limited by high recurrence rates, and unfavorable side effect profiles. Catheter ablation is an alternative or adjunctive option, but is also limited by incomplete efficacy and procedural risk. Copyright © 2017 Elsevier Inc. All rights reserved.

    No new preventive drugs specific to migraine have appeared for the last 20 years and existing acute therapies need improvement. Unfortunately, no animal models can predict the efficacy of new therapies for migraine. Because migraine attacks are fully reversible and can be aborted by therapy......, the headache- or migraine-provoking property of naturally occurring signalling molecules can be tested in a human model. This model has predicted efficacy of nitric oxide synthase inhibition and calcitonin gene-related peptide receptor blockade. The pharmaceutical industry should pay more attention to human...

    Although detoxification cannot, in itself, be considered a treatment for addiction, it is one of the most pivotal phases. In order to facilitate entry into recovery and/or rehabilitation programs, a detoxification treatment has to be experienced as easy and safe by the patient. In consideration of the many inconveniences related to standard withdrawal treatments, there is an interest in developing alternative pharmacological strategies. The main rationales for using anticonvulsants in substance-abuse patients are their lack of addiction potential, evidence support a role of kindling mechanisms in withdrawal syndromes and their efficacy in comorbid psychiatric disorders. The available data currently support the utilization of carbamazepine as a treatment for detoxification from benzodiazepines, alcohol and opiates, and as a useful agent to reduce cocaine consumption. The use of valproate is well corroborated for alcohol detoxification and it seems to be a promising treatment for the reduction of cocaine use; however, it has been found to be ineffective against benzodiazepine withdrawal symptoms. Some preliminary data suggest that lamotrigine could be useful in opiate and cocaine dependence. Gabapentin shows potential as a treatment for cocaine dependence, and some case reports have stimulated interest in this agent for alcohol and benzodiazepine detoxification. Due to its particular pharmacological profile, topiramate is one of the most interesting newer anticonvulsants. It has been found to be efficacious in opiate and possibly benzodiazepine detoxification and also has theoretical potential as a preventive therapy.

    The Médecins Sans Frontières project of Uzbekistan has provided multidrug-resistant tuberculosis treatment in the Karakalpakstan region since 2003. Rates of default from treatment have been high, despite psychosocial support, increasing particularly since programme scale-up in 2007. We aimed to determine factors associated with default in multi- and extensively drug-resistant tuberculosis patients who started treatment between 2003 and 2008 and thus had finished approximately 2 years of treatment by the end of 2010. A retrospective cohort analysis of multi- and extensively drug-resistant tuberculosis patients enrolled in treatment between 2003 and 2008 compared baseline demographic characteristics and possible risk factors for default. Default was defined as missing ≥60 consecutive days of treatment (all drugs). Data were routinely collected during treatment and entered in a database. Potential risk factors for default were assessed in univariate analysis using chi-square test and in multivariate analysis with logistic regression. 20% (142/710) of patients defaulted after a median of 6 months treatment (IQR 2.6-9.9). Factors associated with default included severity of resistance patterns (pre-extensively drug-resistant/extensively drug-resistant tuberculosis adjusted odds ratio 0.52, 95%CI: 0.31-0.86), previous default (2.38, 1.09-5.24) and age >45 years (1.77, 1.10-2.87). The default rate was 14% (42/294) for patients enrolled 2003-2006 and 24% (100/416) for 2007-2008 enrolments (p = 0.001). Default from treatment was high and increased with programme scale-up. It is essential to ensure scale-up of treatment is accompanied with scale-up of staff and patient support. A successful first course of tuberculosis treatment is important; patients who had previously defaulted were at increased risk of default and death. The protective effect of severe resistance profiles suggests that understanding disease severity or fear may motivate against default. Targeted

    Adherence to HCV therapy impacts sustained virological response (SVR) but there are limited data on adherence, particularly among injecting drug users (IDUs). We assessed 80/80 adherence (≥80% of PEG-IFN doses, ≥80% treatment), on-treatment adherence, and treatment completion in a study of treatment of recent HCV infection (ATAHC). Participants with HCV received pegylated interferon (PEG-IFN) alfa-2a (180μg/week, n=74) and those with HCV/HIV received PEG-IFN alfa-2a with ribavirin (n=35), for a planned 24 weeks. Logistic regression analyses were used to identify predictors of PEG-IFN 80/80 adherence. A total of 109 out of 163 patients received treatment (HCV, n=74; HCV/HIV, n=35), with 75% ever reporting IDU. The proportion with 80/80 PEG-IFN adherence was 82% (n=89). During treatment, 14% missed ≥1 dose (on-treatment adherence=99%). Completion of 0-4, 5-19, 20-23, and all 24 weeks of PEG-IFN therapy occurred in 10% (n=11), 14% (n=15), 6% (n=7) and 70% (n=76) of cases, respectively. Participants with no tertiary education were less likely to have 80/80 PEG-IFN adherence (AOR 0.29, p=0.045). IDU prior to or during treatment did not impact 80/80 PEG-IFN adherence. SVR was higher among those patients with ≥80/80 PEG-IFN adherence (67% vs. 35%, p=0.007), but similar among those with and without missed doses during therapy (73% vs. 60%, p=0.309). SVR in those patients discontinuing therapy between 0-4, 5-19, 20-23, and 24 weeks was 9%, 33%, 43%, and 76%, respectively (p<0.001). High adherence to treatment for recent HCV was observed, irrespective of IDU prior to, or during, therapy. Sub-optimal PEG-IFN exposure was mainly driven by early treatment discontinuation rather than missed doses during therapy. Copyright © 2010 European Association for the Study of the Liver.

    To assess prescriber adherence to standard anti-hypertensive treatment guidelines in South Africa, determine if supply data are useful indicators of drug use, and assess the cost implications of not complying with the guidelines. We undertook two studies: an analysis of records of the anti-hypertensive drugs supplied to all 54 public-sector hospitals with a hypertension clinic in KwaZulu-Natal, and a direct-observation survey of anti-hypertensive drug prescriptions presented to pharmacies in a subset of 16 of the 54 hospitals. We calculated the relative use of each anti-hypertensive drug group as a proportion of all anti-hypertensive drugs supplied or prescribed. We ranked drug groups in order of use for comparison with recommended South African standard treatment guidelines, and we compared the proportions derived from supply data with those derived from the prescription survey. Supply data showed that, in line with treatment guidelines, diuretics and angiotensin-converting enzyme inhibitors were the most frequently supplied medicines (42% and 27%, respectively). However, methyldopa - not included in the treatment guidelines - represented 10% of all anti-hypertensives supplied, but the proportion varied widely between hospitals (0-37%). Reserpine, second choice in the treatment guidelines, was used in high amounts by only two hospitals. Calcium channel blockers and beta blockers represented a small proportion of the anti-hypertensive drugs supplied: 6% each. Results from the prescription survey were in concordance with supply data for the most frequently prescribed drugs but gave slightly different estimates of the use of others. Supply data, the most available source of information about drug use in developing countries, are (with some provisos) a reliable data source for the evaluation of adherence to treatment guidelines. Our results showed substantial non-adherence to standard treatment guidelines.

    Full Text Available Alcohol and other drugs of abuse, including psychostimulants and opioids, can induce epigenetic changes: a contributing factor for drug addiction, tolerance and associated withdrawal symptoms. DNA methylation is the major epigenetic mechanism and it is one of more than 200 methylation reactions supported by methyl donor S-adenosylmethionine (SAM. The levels of SAM are controlled by cellular redox status via the folate and vitamin B12-dependent enzyme methionine synthase (MS, for example; under oxidative conditions MS is inhibited, diverting its substrate homocysteine (HCY to the transsulfuration pathway. Alcohol, dopamine and morphine, can alter intracellular levels of glutathione (GSH-based cellular redox status, subsequently affecting S-adenosylmethionine (SAM levels and DNA methylation status. In this discussion, we compile this and other existing evidence in a coherent manner to present a novel hypothesis implicating the involvement of redox-based epigenetic changes in drug addiction. Next, we also discuss how gene priming phenomenon can contribute to maintenance of redox and methylation status homeostasis under various stimuli including drugs of abuse. Lastly, based on our hypothesis and some preliminary evidence, we discuss a mechanistic explanation for use of metabolic interventions / redox-replenishers as symptomatic treatment of alcohol addiction and associated withdrawal symptoms. Hence, the current review article strengthens the hypothesis that neuronal metabolism has a critical bidirectional coupling with epigenetic changes in drug addiction and we support this claim via exemplifying the link between redox-based metabolic changes and resultant epigenetic consequences under the effect of drugs of abuse.

    Full Text Available Background: Viruses play a leading role in human pathology development, causing a large number of infectious diseases in acute, persistent or chronic forms. Although the number of deaths caused by viral infections have decreased significantly today, they continue to be a significant factor in reducing of the population overall productivity. Viral diseases cause additional losses in community related to the duration of the course or disease or its chronization, increased use of health care, loss of working hours, premature death etc. Introduction of the new antiviral drugs into medical practice is accompanied by the emergence of questions to assess its effectiveness and including into existing clinical protocols. So the aim of this work is the development of methodology of choosing and justification of optimal treatment strategy for viral diseases that could be included into certain clinical protocols for managing patients with certain viral diseases. Methodology justification: The methodology based on the method of pharmacoeconomic analysis "cost of illness", takes into account the economic burden of viral diseases: direct costs for treating of disease, indirect costs related to the disease and intangible costs. Algorithm of treatment scheme choice depends on the cost of treatment for the patient without viral disease also as for patient with viral disease. It was proposed to use lower limit priori probability (critical prevalence of viral disease as decision rule in the choice of treatment scheme. Results: Examples of the proposed methodology use show that the choice of the optimal therapeutic scheme for patients with suspected viral disease depends on the current prevalence of this disease among patients with similar clinical symptoms of the disease and its cost, depending on the chosen strategy of therapy. The proposed methodology determines the critical level of viral infection prevalence, which comparing to the current prevalence level is

  6. A Possible Mechanism Underlying the Effectiveness of Acupuncture in the Treatment of Drug Addiction

    Full Text Available Clinical trials are currently underway to determine the effectiveness of acupuncture in the treatment of drug addiction. While there are still many unanswered questions about the basic mechanisms of acupuncture, some evidence exists to suggest that acupuncture can play an important role in reducing reinforcing effects of abused drugs. The purpose of this article is to critically review these data. The neurochemical and behavioral evidence showed that acupuncture's role in suppressing the reinforcing effects of abused drugs takes place by modulating mesolimbic dopamine neurons. Also, several brain neurotransmitter systems such as serotonin, opioid and amino acids including GABA have been implicated in the modulation of dopamine release by acupuncture. These results provided clear evidence for the biological effects of acupuncture that ultimately may help us to understand how acupuncture can be used to treat abused drugs. Additional research using animal models is of primary importance to understanding the basic mechanism underlying acupuncture's effectiveness in the treatment of drug addiction.

    Biologic drugs have provided excellent results in the treatment of moderate to severe psoriasis. Nevertheless, in routine clinical practice, combinations of biologic drugs with phototherapy or systemic drugs can increase efficacy, diminish toxicity, and reduce the cost of treatment. Published experience with these combinations is scarce, although the results are often satisfactory. This review examines the most relevant published experience in the combination of the most studied drug in this field-etanercept-with methotrexate, acitretin, ciclosporin, and narrowband UV-B phototherapy. Findings reported in the literature can help when taking major decisions on the management of biologic and systemic drugs in moderate to severe psoriasis.

    In China, Chloroquine (CQ) and sulfadoxine-pyrimethamine (SP) were abandoned for the treatment of falciparum malaria 20 years ago due to resistance. Subsequent field studies showed a trend of declining CQ and SP resistance in the country. The main purpose of this study was to analyse the molecular markers of antimalarial resistance and thereby to assess the possibility of reintroduction of CQ or SP for falciparum malaria treatment. Plasmodium falciparum field isolates were collected in 2006-2007 from Hainan and Yunnan provinces, China. Nested PCR-sequencing assays were applied to analyse the SNPs in four genes: P. falciparum chloroquine resistance transporter (pfcrt) gene, multi-drug resistance 1 (pfmdr1) gene, dihydrofolate reductase (dhfr) gene and dihydropteroate synthetase (dhps) gene. We found the widespread presence of point mutations in the dhfr and dhps genes which are associated with SP treatment failure. The molecular analyses also showed the fairly high prevalence of point mutation in the pfcrt gene which is linked to CQ resistance. The results of the present study indicate that CQ and SP should not be reintroduced for falciparum malaria treatment in the near future in China.

    Full Text Available The main objectives and strategies for treatment of atrial fibrillation (AF, one of the most common cardiac arrhythmia, are seen. A combination of strategies for heart rate control in patients with atrial fibrillation receiving rhythm-controling therapy is preferred at present, according to current guidelines. Amiodarone, one of the most effective anti-arrhythmic drugs with an extensive evidence base, remains the drug of reserve because of serious side effects. A new drug, dronedarone, has electrophysiological properties attributable to all four classes of antiarrhythmic drugs. According to meta-analysis of randomized clinical trials dronedarone is inferior to amiodarone in prevention of AF recurrences, but it is superior to amiodaron in safety. However , in 2011 dronedarone was included in the Food and Drug Administration (FDA list of drugs that require further analysis in connection with appearance of the new information about its safety.

    Full Text Available Ultrasound is an emerging modality for drug delivery in chemotherapy. This paper reviews this novel technology by first introducing the designs and characteristics of three classes of drug/gene vehicles, microbubble (including nanoemulsion, liposomes, and micelles. In comparison to conventional free drug, the targeted drug-release and delivery through vessel wall and interstitial space to cancerous cells can be activated and enhanced under certain sonication conditions. In the acoustic field, there are several reactions of these drug vehicles, including hyperthermia, bubble cavitation, sonoporation, and sonodynamics, whose physical properties are illustrated for better understanding of this approach. In vitro and in vivo results are summarized, and future directions are discussed. Altogether, ultrasound-mediated drug/gene delivery under imaging guidance provides a promising option in cancer treatment with enhanced agent release and site specificity and reduced toxicity.

    Antiepileptic drugs are the first line treatment for trigeminal neuralgia (TN). Carbamazepine and oxcarbazepine are the most studied with well-known efficacy. Eslicarbazepine acetate is a third-generation antiepileptic drug that has not previously been evaluated for the treatment of TN. We aim to assess the efficacy, tolerability, and safety of eslicarbazepine for TN. Retrospective, open-label, multicentric, intention-to-treat study. We included patients older than 18 years who met the ICHD-3 beta diagnostic criteria for TN. We evaluated the variation of intensity and frequency of pain paroxysms before and after treatment with eslicarbazepine. Secondary objectives assessed were tolerability and safety of eslicarbazepine. Eighteen patients were included, 15 women, mean age 65.2 years-old, mean follow-up 21.1 months. The mean number of drugs tested before eslicarbazepine was 2; ten patients used eslicarbazepine as monotherapy. After the treatment with ESL, the median of pain intensity improved from 9.5 to 2.5 (p eslicarbazepine for this reason. Despite this, 16 patients (88.9%) noticed a good subjective tolerance to eslicarbazepine. The retention rate at 6 months was 77.8% and at 12 months 61.1%. Our study supports the hypothesis that eslicarbazepine acetate is an effective, safe, and well-tolerated treatment for the treatment of TN. Further studies are warranted to corroborate these results.

    Directory of Open Access Journals (Sweden)

    Cynthia V. Rivero

    2016-01-01

    Full Text Available Chagas disease is a life-threatening illness caused by the protozoan parasite Trypanosoma cruzi. One of the characteristics of chronic chagasic infection is the parasitic persistence in cardiac and smooth muscle tissues. For this reason etiologic treatment of Chagas disease in all phases of infection is highly recommended. Despite the high number of trypanocidal drugs that have been discovered in the last years, only two compounds, Benznidazole and Nifurtimox remain as the unique drugs approved for Chagas treatment. Far from ideal, these drugs display low sensitivity and specificity resulting in limited applications, mainly in the onset of the acute phase. Thus there is an urgent need to validate new anti- T. cruzi drugs that can be applied even in the cases of chronic patients, those who today have no safe and effective treatment available. This paper reviews the most important compounds that have been tested in clinical trials and the results obtained to date.

    2005-11-01

    This article reviews the clinical use of stents in the treatment of coronary artery disease and the rationale for the use of degradable, drug-eluting polymer stents. The authors note the challenges of using off-the-shelf polymers for the development of degradable stents, as well as the interplay between polymer properties and a functional stent design. Drug-eluting metal stents are the most significant advancement in the treatment of coronary artery disease, and have significantly reduced the occurrence of in-stent restenosis after placement. Some regard drug-eluting metal stents as the final technologic advancement in the treatment of coronary artery disease, others consider the future development of degradable, drug-eluting stents as the next logical step.

    Obesity is a serious and costly disease that is growing in epidemic proportions. Obesity-related hospitalizations have nearly tripled from 1996 to 2009. If the current trend in the growth of obesity continues, the total healthcare costs attributable to obesity could reach $861 billion to $957 billion by 2030. The American Medical Association has officially recognized obesity as a disease. Obesity is a public health crisis affecting approximately more than 33% of Americans and costing the healthcare system more than $190 billion annually. To review the 2 new drugs that were recently approved by the US Food and Drug Administration (FDA) for the treatment of obesity, lorcaserin HCl (Belviq) and phentermine/topiramate (Qsymia) and their potential impact on the treatment of obese patients. Lifestyle modification is the first and mainstay treatment for obesity. Antiobesity drugs are indicated as adjuncts to a healthy, low-fat, low-calorie diet and an exercise plan. Currently, 4 drugs are approved by the FDA for the treatment of obesity, 2 of which were approved after June 2012. These 2 drugs, Belviq and Qsymia, have added new tools for the treatment of obesity. In addition to reducing body mass index, these drugs have been shown to reduce hemoglobin A1c levels in patients with diabetes and blood pressure levels in patients with hypertension, as well as to decrease lipid levels in patients with hyperlipidemia. This article reviews the drugs' mechanisms of action, evaluates landmark clinical studies leading to the FDA approval of the 2 drugs, their common side effects, and the benefits these new drugs can provide toward the management of the obesity epidemic that are different from other medications currently available. The weight loss seen in patients who are using the 2 new medications has been shown to further improve other cardiometabolic health parameters, including blood pressure, blood glucose levels, and serum lipid levels. Based on clinical trials evidence, it is

    Distinguishing new from recrudescent infections in post-treatment episodes of malaria is standard in anti-malarial drug efficacy trials. New infections are not considered malaria treatment failures and as a result, the prevention of subsequent episodes of malaria infection is not reported as a study outcome. However, in moderate and high transmission settings, new infections are common and the ability of a short-acting medication to cure an initial infection may be outweighed by its inability to prevent the next imminent infection. The clinical benefit of preventing new infections has never been compared to that of curing the initial infection. Children enrolled in a sulphadoxine-pyrimethamine efficacy study in Blantyre, Malawi from 1998-2004 were prospectively evaluated. Six neutral microsatellites were used to classify new and recrudescent infections in children aged less than 10 years with recurrent malaria infections. Children from the study who did not experience recurrent parasitaemia comprised the baseline group. The odds of fever and anaemia, the rate of haemoglobin recovery and time to recurrence were compared among the groups. Fever and anemia were more common among children with parasitaemia compared to those who remained infection-free throughout the study period. When comparing recrudescent vs. new infections, the incidence of fever was not statistically different. However, children with recrudescent infections had a less robust haematological recovery and also experienced recurrence sooner than those whose infection was classified as new. The results of this study confirm the paramount importance of providing curative treatment for all malaria infections. Although new and recrudescent infections caused febrile illnesses at a similar rate, recurrence due to recrudescent infection did have a worsened haemological outcome than recurrence due to new infections. Local decision-makers should take into account the results of genotyping to distinguish new

    The rate of alcohol and drug dependency is high among homeless persons in Norway as well as in other Western societies. National homeless surveys also show a certain correlation between discharge from institutions and homelessness. However, the rate of homelessness versus the rate with fixed abode at the end of specialised alcohol and drug treatment has not been examined using quantitative methods. A cross-sectional survey was conducted in alcohol and drug treatment units in the national health services and private clinics. The survey investigates the housing outcome at the end of treatment compared to the situation at the start of treatment using an individual questionnaire for patients ending treatment in a specific time window. Housing outcome is measured by the odds ratio of having a fixed abode at the end of treatment in relation to main intoxicating substance, type of treatment (in- and outpatient), completing versus cutting short the treatment, housing situation at the start of treatment, socioeconomic capital, mental health problems, individual plan, medical assisted treatment, and a set of background variables. The housing versus homeless situation hardly changes during the treatment period. In both a bivariate analysis and a simple multivariate model, principal intoxicating substance is the strongest predictor of having a fixed abode both before and after treatment. However, a more sophisticated analysis indicates that socioeconomic resources and social capital play along with the preferred intoxicating substance as predictors of having permanent housing. After more than a decade of a housing-led national homeless policy, and wide embracement of Housing First approaches in the European Union, homeless persons entering specialised alcohol and drug treatment are likely to return to the streets and hostels at the end of treatment. Access to housing after treatment is very limited for those lacking resources to solve their housing problem without assistance

    The potential of the marine environment to produce candidate compounds (structures) as leads to, or even direct drugs from, has been actively discussed for the last 50 or so years. Over this time frame, several compounds have led to drugs, usually in the area of cancer (due to funding sources). This review is designed to show where there have been successes, but also to show that in a number of disease areas, there are structures originally isolated from marine invertebrates and free-living microbes that have potential, but will need to be "adopted" by pharmaceutical houses in order to maximize their potential.

    Despite promising trends of the efficacy of mobile health (mHealth) based strategies to a broad range of health conditions, very few if any studies have been done in terms of the examining the use of mHealth in HIV prevention efforts among people who use drugs in treatment. Thus, the goal of this study was to gain insight into the real-world acceptance of mHealth approaches among high-risk people who use drugs in treatment. A convenience sample of 400 HIV-negative drug users, who reported drug- and/or sex-related risk behaviors, were recruited from a methadone clinic in New Haven, Connecticut. Participants completed standardized assessments of drug- and sex-related risk behaviors, neurocognitive impairment (NCI), and measures of communication technology access and utilization, and mHealth acceptance. We found a high prevalence of current ownership and use of mobile technologies, such as cell phone (91.5%) including smartphone (63.5%). Participants used mobile technologies to communicate mostly through phone calls (M = 4.25, SD = 1.24), followed by text messages (M = 4.21, SD = 1.29). Participants expressed interest in using mHealth for medication reminders (72.3%), receive information about HIV (65.8%), and to assess drug-related (72.3%) and sex-related behaviors (64.8%). Furthermore, participants who were neurocognitively impaired were more likely to use cell phone without internet and show considerable interest in using mHealth as compared to those without NCI. The findings from this study provide empirical evidence that mHealth-based programs, specifically cell phone text messaging-based health programs, may be acceptable to this high-risk population.

    The drug development process for CNS indications is hampered by a paucity of preclinical tests that accurately predict drug efficacy in humans. Here, we show that a wide variety of CNS-active drugs induce characteristic alterations in visual stimulus–induced and/or spontaneous eye movements in mice. Active compounds included sedatives and antipsychotic, antidepressant, and antiseizure drugs as well as drugs of abuse, such as cocaine, morphine, and phencyclidine. The use of quantitative eye-movement analysis was demonstrated by comparing it with the commonly used rotarod test of motor coordination and by using eye movements to monitor pharmacokinetics, blood-brain barrier penetration, drug-receptor interactions, heavy metal toxicity, pharmacologic treatment in a model of schizophrenia, and degenerative CNS disease. We conclude that eye-movement analysis could complement existing animal tests to improve preclinical drug development. PMID:21821912

    Only a few studies analyzed the pharmacoeconomics of allergen immunotherapy compared with drug treatment in subjects with allergic rhinitis and asthma. This study was aimed at evaluating whether allergen immunotherapy has an economic advantage on standard antiallergic drugs in patients with pollen-induced rhinitis and asthma. Thirty patients with rhinitis and asthma caused by Parietaria pollen were included in the study, 20 (11 men and 9 women; mean age, 35.45 +/- 10.45 years) were treated with subcutaneous immunotherapy by a Parietaria judaica extract (Alustal, Stallergénes, Antony, France) by a conventional build-up schedule in 12 weeks and a maintenance treatment every 4 weeks for 3 years, and 10 (6 men and 4 women; mean age, 31.90 +/- 10.97 years) were treated with antiallergic drugs. Each patient was evaluated before starting the treatment and annually for 6 years in the pollen period of Parietaria by means of nose, eyes, and lung symptom scores, along with drug consumption registered in diary cards. In other specifically designated cards general practitioner's or specialist's visits, the number of desensitizing injections and the number of boxes of antiallergic drugs were registered. A significant difference in favor of immunotherapy plus drug treatment versus drug treatment alone was observed, reaching a cost reduction of approximately 15% the second year and 48% the third year, with a highly statistical significance that was maintained up to the sixth year, i.e., 3 years after stopping immunotherapy, when an 80% reduction was found. The net saving for each patient at the final evaluation corresponded to euros 623 (dollars 830)/year. These findings confirm some previous observations in studies from Germany and the United States that subcutaneous immunotherapy has significant economic advantages over antiallergic drug treatment in the long term.

    Acne vulgaris is a common skin condition with substantial cutaneous and psychologic disease burden. Studies suggest that the emotional impact of acne is comparable to that experienced by patients with systemic diseases, like diabetes and epilepsy. In conjunction with the considerable personal burden experienced by patients with acne, acne vulgaris also accounts for substantial societal and health care burden. The pathogenesis and existing treatment strategies for acne are complex. This article discusses the epidemiology, pathogenesis, and treatment of acne vulgaris. The burden of disease in the United States and future directions in the management of acne are also addressed. Copyright © 2012 Elsevier Inc. All rights reserved.

    To present a procedure for establishing treatment guidelines during pregnancy and, as an application of the method, the recommendations for treatment of pruritus. A preliminary survey was carried out among participants of the study group to determine drug choices for treatment of pruritus during pregnancy. Literature data on the selected drugs were analyzed. Recommendations for treatment were proposed, taking into account for most efficient agents and the least toxic for the fetus. This draft was submitted to all participants of the study group; criticism and suggestions were gathered. A new draft was evolved and repeatedly submitted to participants until consensus was reached. Study group set up in southwestern France, with the help of national experts. Forty-three general practitioners, six gynecologists and/or obstetricians, five pharmacologists, two dermatologists, and an embryologist. The main recommendations for treatment of pruritus during pregnancy are to begin with topical treatment; emollient bath additives, moisturizing cream, talc. If insufficient, a systemic treatment should be added. Antihistamines are prescribed first: hydroxyzine or dexchlorpheniramine is used during the first 2 months. From the third month, the same agents can be used, as can mequitazine. The duration of treatment can be up to 10 days. The group's second choice was benzodiazepine (oxazepam) as second-line treatment. Strategies for treatment of diseases during pregnancy are not always well defined. For many common diseases, very few data are available concerning drug use in pregnant women. The study group, based on consensus among participants, proposed treatment guidelines.

    Full Text Available Sulfur Mustard (SM, a cytotoxic vesicant chemical warfare agent, has powerful irritant and blistering effects on the skin, eyes and respiratory tract. Since during the Iraq-Iran war, many Iranian soldiers and civilians were exposed to SM, there are several victims still suffering from long-term cutaneous, ocular and pulmonary complications. Currently, there is no definite treatment for long-term complications of SM, and only supportive medical care is being taken to minimize the symptoms. In this study, we compared the cost-effectiveness of common drugs that are used against long-term SM-induced complications in Iranian patients. In this review article, electronic databases were checked using the following key words: sulfur mustard, lung, skin, eye, cost-effectiveness, pharmacoeconomics and treatment. Abstracts of non-English papers and proceedings of congresses on SM were also assessed. Among the studied drugs, high-dose oral N-acetyl cysteine and long-acting inhaled corticosteroids against respiratory complications, topical corticosteroids and oral antihistamines against cutaneous complications and non-steroidal anti-inflammatory drugs and corticosteroids ophthalmic drops against ocular complications were found to be cost-effective. Usage of different drugs in the treatment of SM injuries in Iran, have imposed a significant economic burden to patients and their families because many drugs that are effective against chemical injuries are not covered by insurance. In addition, the development of more effective drugs in this field is considered as an urgent demand that should be noticed by the pharmaceutical industry.
