Since for the sales of over-the-counter (OTC) medicines, prescribing physicians are not involved, and written instructions on/in the medicine boxes are inefficient, druggists and pharmacists are important gatekeepers in preventing customers' accidents. In this study we investigated the sales routines, and compliance with sales protocols, in order to evaluate that gatekeeper's function. By means of the mystery shopping method, 228 pharmacies and drugstores in The Netherlands were visited and a naproxen 275mg medium-risk medicine was requested for a (fictitious) patient who was suffering from severe back pains. According to the sales protocols the vendors should never sell the requested medicine, because the mystery shoppers only gave an answer to one of the four mandatory sales protocol questions. Furthermore, the requested medicine is not the right or best choice for back pains. Four different scenarios were used in a 2×2 design (8-year-old patient vs. 25-year-old patient, and 1 box with 12 pills vs. 3 boxes with 12 pills). Of the drugstores and pharmacies only 16.7% complied with the sales protocols and did not sell the specific (or comparable) medicine, after asking all four mandatory questions (or already after one, two or three questions). Most vendors (83.3%) did not comply and sold the requested medicine, a comparable medicine, or even a more risky medicine after no question at all (or after asking some or even all four questions). Although both score low, pharmacists show better compliance (23.9%) than druggists (10.1%). When it comes to OTC medicines, druggists and pharmacists largely commit sloppy sales. The expected gatekeeping function of pharmacists and druggists is very limited, and customers might be in danger of inappropriate medicine selection, quantity and usage. We call for thorough evaluation of the over-the-counter system, improvement of the educational programs for medicine providers, and national campaigns to inform the public. Copyright �

2016-09-01

Full Text Available Background: Over-the-counter medicines (OTC are widely available and can be purchased without a prescription. Their availability means that a customer may choose to purchase them without the involvement of a pharmacy/pharmacist. It is important to understand customer OTC purchasing perceptions and behaviour from a pharmacy to better understand the needs and opportunities in this space. Objective: This study aimed to examine customers’ key expectations and what they value when purchasing OTC and how the effect of health status/stress and perceived risks/benefits of purchasing OTCs from a pharmacy may influence their OTC shopping behaviour. Methods: Customers from two metropolitan pharmacies across two different suburbs in Brisbane, Queensland, Australia completed a self-administered questionnaire. Data collection was conducted over a six-week period. The questionnaire examined demographics, current level of health and stress, as well as a range of questions (seven-point Likert-scale examining perceived benefits and risks, what they value, trust and expect when purchasing OTC. Results: A total of 86 customers from a broad range of demographics were captured in this study. When asked about their current health state, 41% and 23% respectively indicated that they were stressed and tense when they arrived at the pharmacy but many were feeling well (38%. Most customers strongly agreed/agreed that trust in the advice from a pharmacy (96%, trust in the products (73%, and the altruistic approach of a pharmacy (95% were critical to them. Further, 82% and 78% respectively disagreed that time pressures or costs were concerns, despite many feeling tense and stressed when they came in. When asked where they intend to buy their future OTC, 89% indicated pharmacy instead of a supermarket. Conclusions: High levels of trust, confidence and sense of altruism and care were key factors for customers buying OTC from a pharmacy, regardless of time pressures, costs or

In this paper the practical problem of nuclear medicine gamma counters calibration has been solved by using dose calibrators CRC-15R with standard error ±5%. The samples from technetium generators have been measured both by dose calibrators CRC-15R and gamma counter ICN Gamma 3.33 taking into account decay correction. Only the linear part of the curve has practical meaning. The advantage of this procedure satisfies the requirements from international standards: the calibration of sources used for medical exposure be traceable to a standard dosimetry laboratory and radiopharmaceuticals for nuclear medicine procedures be calibrated in terms of activity of the radiopharmaceutical to be administered.

A Survey of Teenagers' Attitudes Toward Moving Oral Contraceptives Over the Counter.

Science.gov (United States)

Manski, Ruth; Kottke, Melissa

2015-09-01

Evidence suggests that over-the-counter access to oral contraceptives may help expand use among adult women. Teenagers may particularly benefit from this approach, as they experience disproportionately high rates of unintended pregnancy and face unique challenges accessing contraceptives. However, limited research has explored teenagers' attitudes toward over-the-counter access. In 2014, a sample of 348 females aged 14-17, recruited via Facebook advertisements, participated in an online survey assessing teenagers' attitudes toward over-the-counter access and their understanding of how to use oral contraceptives after reading a prototype over-the-counter product label. Differences by participants' characteristics were assessed in bivariate analyses (Pearson chi-square and Fisher's exact tests for categorical measures, and independent t tests and one-way analyses of variance for continuous measures). Seventy-three percent of participants supported over-the-counter access, and 61% reported that they would likely use oral contraceptives available through this approach. Few subgroup differences were found. Notably, sexually experienced participants were significantly more likely than others both to support this approach (85% vs. 63%) and to be interested in obtaining oral contraceptives this way (77% vs. 48%). Participants understood an average of 7.1 of eight key concepts that the prototype product label was intended to convey; no significant differences were found among subgroups. Over-the-counter access may be a promising approach for providing oral contraceptives to teenagers. Additional research is needed to evaluate whether teenagers can screen themselves for contraindications to oral contraceptive use and correctly use oral contraceptives obtained over the counter.

Popularity and customer preferences for over-the-counter Chinese medicines perceived by community pharmacists in Shanghai and Guangzhou: a questionnaire survey study

Science.gov (United States)

2014-01-01

Background This study interviewed community pharmacists in Shanghai and Guangzhou for their perception of the popular categories of over-the-counter (OTC) Chinese medicines and the factors affecting customer preferences for OTC Chinese medicines. Methods A cross-sectional survey was carried out in six main administrative districts in Guangzhou and eight main administrative districts in Shanghai, China. Descriptive statistical analysis was conducted in this study. Results OTC Chinese medicines contributed 21–50% among all the pharmaceutical sales by the community pharmacies. The prevalent categories of OTC Chinese medicines were common cold medicines, respiratory system medicines, digestive system agents, gynecological medicines, health tonic medicines, and qing re (heat-clearing) and qu du (detoxifying) medicines. Customers were more concerned about medical factors of OTC Chinese medicines than business factors. Among the medical factors, the most important was drug safety, followed by efficacy, contraindications, indications, and side effects. Among the business factors, the most important were brand and price. Conclusions This study identified the top sales categories of OTC Chinese medicines in Shanghai and Guangzhou and the important factors such as drug safety, efficacy, period of validity, contraindications, and indications that are affecting the customer preferences for OTC Chinese medicines.

Full Text Available A pharmacist in today’s world has a great responsibility – to help and educate patients about diverse ways for effective self-treatment. Whereas self-care is becoming increasingly popular among patients today the availability of over-the-counter medications makes it possible for patients to treat numerous conditions on their own but still under the supervision of a healthcare provider. During the pharmacist-patient encounter, the pharmacist’s obligation is to evaluate the patient’s medical condition, provide proper advice and counsel the patient on the proper course of treatment to be taken. Also by employing effective over the counter (OTC counseling as the most proper means in a pharmacist/patient communication process and, accordingly, rapport building in the OTC area, the pharmacist needs to demonstrate high energy, enthusiasm, respect, empathy, know-how of sensitive intercultural issues alongside personal appearance, body language, eye contact that all together make his/her personal “signature”. Accordingly, apart from patient education, the primary objective of OTC counseling becomes to educate pharmacists on basic principles used in assisting patients in the selection of over-the-counter (OTC products, provide examples of proper communication techniques for effective patient counseling concerning the OTC products (i.e. dosage, administration technique, storage, food and beverage interaction, monitoring etc where the pharmacist plays the key role in helping patients maximize their pharmaceutical care.

Hellier, Elizabeth; Tucker, Mike; Kenny, Natalie; Rowntree, Anna; Edworthy, Judy

2010-09-01

This study aimed to examine the utility of using color and shape to differentiate drug strength information on over-the-counter medicine packages. Medication errors are an important threat to patient safety, and confusions between drug strengths are a significant source of medication error. A visual search paradigm required laypeople to search for medicine packages of a particular strength from among distracter packages of different strengths, and measures of reaction time and error were recorded. Using color to differentiate drug strength information conferred an advantage on search times and accuracy. Shape differentiation did not improve search times and had only a weak effect on search accuracy. Using color to differentiate drug strength information improves drug strength identification performance. Color differentiation of drug strength information may be a useful way of reducing medication errors and improving patient safety.

Global malaria control strategies highlight the need to increase early uptake of effective antimalarials for childhood fevers in endemic settings, based on a presumptive diagnosis of malaria in this age group. Many control programmes identify private medicine sellers as important targets to promote effective early treatment, based on reported widespread inadequate childhood fever treatment practices involving the retail sector. Data on adult use of over-the-counter (OTC) medicines is limited. This study aimed to assess childhood and adult patterns of OTC medicine use to inform national medicine retailer programmes in Kenya and other similar settings. Large-scale cluster randomized surveys of treatment seeking practices and malaria parasite prevalence were conducted for recent fevers in children under five years and recent acute illnesses in adults in three districts in Kenya with differing malaria endemicity. A total of 12, 445 households were visited and data collected on recent illnesses in 11, 505 children and 19, 914 adults. OTC medicines were the most popular first response to fever in children with fever (47.0%; 95% CI 45.5, 48.5) and adults with acute illnesses (56.8%; 95% CI 55.2, 58.3). 36.9% (95% CI 34.7, 39.2) adults and 22.7% (95% CI 20.9, 24.6) children using OTC medicines purchased antimalarials, with similar proportions in low and high endemicity districts. 1.9% (95% CI 0.8, 4.2) adults and 12.1% (95% CI 16.3,34.2) children used multidose antimalarials appropriately. Although the majority of children and adults sought no further treatment, self-referral to a health facility within 72 hours of illness onset was the commonest pattern amongst those seeking further help. In these surveys, OTC medicines were popular first treatments for fever in children or acute illnesses in adults. The proportions using OTC antimalarials were similar in areas of high and low malaria endemicity. In all districts, adults were more likely to self-treat with OTC

Full Text Available Consumers are confident managing minor ailments through self-care, often self-medicating from a range of over-the-counter (OTC medicines available from community pharmacies. To minimise risks, pharmacy personnel endeavour to engage in a consultation when consumers present with OTC enquiries however they find consumers resistant. The aim was to determine stakeholder perspectives regarding barriers and facilitators for information exchange during OTC consultations in community pharmacies and to understand the elicited themes in behavioural terms. Focus groups were undertaken with community pharmacist, pharmacy assistant and consumer participants. Independent duplicate analysis of transcription data was conducted using inductive and framework methods. Eight focus groups involving 60 participants were conducted. Themes that emerged indicated consumers did not understand pharmacists’ professional role, they were less likely to exchange information if asking for a specific product than if asking about symptom treatment, and they wanted privacy. Consumers were confident to self-diagnose and did not understand OTC medicine risks. Pharmacy personnel felt a duty of care to ensure consumer safety, and that with experience communication skills developed to better engage consumers in consultations. They also identified the need for privacy. Consumers need education about community pharmacists’ role and responsibilities to motivate them to engage in OTC consultations. They also require privacy when doing so.

2016-01-01

Use of over-the-counter analgesics among adolescents has increased markedly. High consumption of over-the-counter analgesics among adolescents is associated with frequent pain, lower self-esteem, reduced sleep, lower educational ambition, binge drinking, higher caffeine consumption, and part-time employment. Knowledge about life experiences of adolescents who frequently use over-the-counter analgesics may be useful to prevent health problems. The purpose of the study was to increase knowledge about adolescents who suffer from frequent pain and have a high consumption of over-the-counter analgesics. A qualitative study, employing one-on-one, in-depth interviews using a thematic interview guide. Data were collected in Norway in 2013-2014. Three boys and sixteen girls; aged 14-16 years, who continuously consumed over-the-counter analgesics were recruited from ten high schools in urban and suburban districts. Candidate participants were excluded if they were medically diagnosed with an acute or chronic illness, requiring extended use of over-the-counter analgesics within the last year. The interviews were taped, transcribed and analysed as text according to Kvale's three contexts of interpretation: self-understanding, common sense and theory. All participants disclosed unresolved physical and psychosocial distress characterized as pain. Frequent pain from various body parts made everyday life challenging. Methods of pain self-appraisal and over-the-counter analgesics use often mimicked maternal patterns. Participants reported being raised under unpredictable circumstances that contributed to long lasting family conflicts and peer-group problems. Participants wanted to feel appreciated and to be socially and academically successful. However, pain reduced their ability to manage everyday life, hampered experienced possibilities for success, and made social settings difficult. Childhood experiences influence how adolescents experience pain and use over-the-counter

Informational and symbolic content of over-the-counter drug advertising on television.

Science.gov (United States)

Tsao, J C

1997-01-01

The informational and symbolic content of 150 over-the-counter drug commercials on television are empirically analyzed in this study. Results on the informational content suggest that over-the-counter drug ads tend to focus on the concern of what the drug will do for the consumer, rather than on the reasons why the drug should be ingested. Accordingly, advertising strategy is centered on consumer awareness of the product as the primary goal. Educational commitment, however, did not seem to be blended into the promotional efforts for over-the-counter drugs. Findings on the symbolic content of over-the-counter drug ads reveal that drug images have been distorted. Performance of most drugs has been portrayed to be simple resolutions to relieve the symptom. Moreover, a casual attitude toward drug usage is encouraged in the commercials, while time lapse of drug effects is overlooked.

2017-08-01

Background The unintentional misuse of over-the-counter sleep aids among older adults is an important public health problem and a focus of Healthy People 2020. Accordingly, the 2015 Beers Criteria for Potentially Inappropriate Medication Use in Older Adults recommends that individuals 65 years or older avoid use of diphenhydramine and doxylamine; however, many over-the-counter sleep products contain these active ingredients. Objective To identify the proportion of older adults using an over-the-counter medication containing diphenhydramine or doxylamine, and compare their characteristics with older adults using an over-the-counter medication that does not contain these ingredients. Setting Study participants were recruited from the Community Registry of the Pittsburgh Claude D. Pepper Older Americans Independence Center. Method The study sample was taken from a larger survey of 1025 participants on sleep health and over-the-counter sleep medication use conducted from February to April 2015. A subset of 169 participants aged 65 and older reporting taking at least one over-the-counter product to improve sleep within the past 30 days (16.5%) were selected for our analysis on associations between participant characteristics and potentially inappropriate use of over-the-counter sleep medications. Main outcome measure The proportion and characteristics of older adults taking at least one over-the-counter medication containing diphenhydramine or doxylamine. Results Of the 223 over-the-counter sleep medications listed by participants, 115 (52%) contained diphenhydramine or doxylamine. Using the Beers Criteria, we found that more than half of participants (59%) had used a potentially inappropriate over-the-counter medication containing diphenhydramine or doxylamine to improve sleep within the past 30 days. Participants taking at least one diphenhydramine or doxylamine containing medication were less likely to be aware of any safety risks in taking over-the-counter sleep

Urbonas, Gvidas; Kubilienė, Loreta

2016-04-01

Community pharmacies have an increasing role in self-medication and community health is dependent on the quality of counselling services provided to patients. Some studies show that pharmacists' job satisfaction affects their work quality; other studies found that higher involvement in clinical services increases pharmacists' job satisfaction. To test the relationship between job satisfaction and over-the-counter counselling practice at community pharmacies. Community pharmacies in Lithuania. A convenience sample (n = 305) of community pharmacists participated in the cross-sectional survey where they expressed satisfaction with job and reported on their over-the-counter counselling behaviour on self-report scales. The Partial Least Squares Structural Equation Modelling approach was employed for data analysis. The strength of the relationship between job satisfaction and over-the-counter counselling service. A bidirectional relationship between job satisfaction and over-the-counter counselling service was found. In addition, job satisfaction and over-the-counter counselling quality depended on pharmacists' age. Organizations were recommended to create a counselling friendly environment that would increase pharmacists' job satisfaction and, in return, counselling quality. Also, additional motivation of the retired pharmacists, as well as development of counselling skills of the younger pharmacy workforce, were seen as a means to improve both organizational climate and counselling quality over the counter.

We evaluated changes in the use of non-steroidal anti-inflammatory drugs (NSAIDs), non-opioid analgesics and cough and cold medicines and its relation with the use of antibiotics after the over-the-counter (OTC) antibiotic sales restrictions in Mexico and Brazil. IMS Health provided retail quarterly data from the private sectors in Mexico and Brazil from the first quarter of 2007 to the first quarter of 2013. Data of each active substance of antibiotics, easily accessible medicines perceived as antibiotics substitutes (cough and cold medicines, analgesics and NSAIDs-the latter two being combined in the analyses), and medicines to control for external factors that can affect the medicines usage trend (antihypertensives) were converted from kilograms to defined daily doses per 1000 inhabitants days (DDD/TID). Interrupted time series were used to estimate changes in level of medicines use at the intervention point and slope after the regulation. The Gregory-Hansen cointegration test was used to explore the relation between the use of antibiotics and perceived substitutes. After the regulation in Mexico NSAIDs-analgesics usage level increased by 1.1 DDD/TID with a slope increase of 0.2 DDD/TID per quarter and the cough and cold medicines usage level increased by 0.4 DDD/TID. In Brazil NSAIDs-analgesics usage level increased by 1.9 DDD/TID, and cough and cold medicines did not change. In the two countries, NSAIDs-analgesics usage changes were related with antibiotic usage changes; in Mexico cough and cold medicines usage changes had a relation with the antibiotics usage changes. These results showed a substitution effect on the use of other medicines, especially NSAIDs and analgesics, after reinforcement of OTC antibiotics sales restrictions. These regulations aimed to improve the antibiotics use and as a consequence reduce antimicrobial resistance; however, this type of policies should be comprehensive and take into account the potential substitution effects on the use

With a coating of gold nanoparticles (AuNPs), over-the-counter (OTC) drugs and Chinese herbal medicine granules in KBr pellets could be analyzed by Fourier Transform Infra-red (FT-IR) spectroscopy and Surface-assisted Laser Desorption/Ionization mass spectrometry (SALDI-MS). FT-IR spectroscopy allows fast detection of major active ingredient (e.g., acetaminophen) in OTC drugs in KBr pellets. Upon coating a thin layer of AuNPs on the KBr pellet, minor active ingredients (e.g., noscapine and loratadine) in OTC drugs, which were not revealed by FT-IR, could be detected unambiguously using AuNPs-assisted LDI-MS. Moreover, phytochemical markers of Coptidis Rhizoma (i.e. berberine, palmatine and coptisine) could be quantified in the concentrated Chinese medicine (CCM) granules by the SALDI-MS using standard addition method. The quantitative results matched with those determined by high-performance liquid chromatography with ultraviolet detection. Being strongly absorbing in UV yet transparent to IR, AuNPs successfully bridged FT-IR and SALDI-MS for direct analysis of active ingredients in the same solid sample. FT-IR allowed the fast analysis of major active ingredient in drugs, while SALDI-MS allowed the detection of minor active ingredient in the presence of excipient, and also quantitation of phytochemicals in herbal granules.

Within the competitive pharmacy market environment, community pharmacies are required to develop efficient marketing strategies based on contemporary information about consumer behavior in order to attract clients and develop customer loyalty. This study aimed to investigate the consumers' preferences concerning the selection of pharmacy and over-the-counter (OTC) medicines, and to identify customer segments in relation to these preferences. A cross-sectional study was conducted between February and March 2016 on a convenient quota sample of 300 participants recruited in the metropolitan area of Thessaloniki, Greece. The main instrument used for data collection was a structured questionnaire with close-ended, multiple choice questions. To identify customer segments, Two-Step cluster analysis was conducted. Three distinct pharmacy customer clusters emerged. Customers of the largest cluster (49%; 'convenience customers') were mostly younger consumers. They gave moderate to positive ratings to factors affecting the selection of pharmacy and OTCs; convenience, and previous experience and the pharmacist's opinion, received the highest ratings. Customers of the second cluster (35%; 'loyal customers') were mainly retired; most of them reported visiting a single pharmacy. They gave high ratings to all factors that influence pharmacy selection, especially the pharmacy's staff, and factors influencing the purchase of OTCs, particularly previous experience and the pharmacist's opinion. Customers of the smallest cluster (16%; 'convenience and price-sensitive customers') were mainly retired or unemployed with low to moderate education, and low personal income. They gave the lowest ratings to most of the examined factors; convenience among factors influencing pharmacy selection, whereas previous experience, the pharmacist's opinion and product price among those affecting the purchase of OTCs, received the highest ratings.

Tobacco counter-advertising: a review of the literature and a conceptual model for understanding effects.

Science.gov (United States)

Agostinelli, Gina; Grube, Joel W

2003-01-01

The tobacco counter-advertising literature is reviewed as it relates to basic process questions concerning what makes counter-advertisements effective. Limitations in addressing (a) counter-advertisement content and the psychological mediators targeted, (b) counter-advertisement style and the affective reactions targeted, (c) prior smoking experience, and (d) other audience factors are enumerated. A theoretical model based on alcohol advertising research is presented to address those limitations. The model addresses the practical research question of predicting when tobacco counter-advertising will work by examining the independent influence of each of these enumerated factors, as well as how these factors operate in concert, qualifying each other. The model also addresses the process question of explaining how counter-advertising works by identifying affective and cognitive processes as mediators. By understanding the processes that underlie the qualified findings, one can better advise the designers of tobacco counter-advertisements how to be more effective.

How do Danish community pharmacies vary in engaging customers in medicine dialogues at the counter - an observational study.

Kaae, Susanne; Saleem, Sahdia; Kristiansen, Maria

2014-07-01

Counter counseling is an important part of community pharmacies service delivery. Difficulties arise because customers appear less interested than the staff in discussing their medicine. It is unclear how individual pharmacies differ with regard to overcoming these obstacles. This study explores differences in the communication practices of pharmacies with regard to engaging customers in medicine dialogues. The work of Stevenson et al. describing five types of interaction scenarios at the counter was used for structured overt non-participant observations of 100 encounters in each of five Danish pharmacies. Variation in pharmacies success in engaging customers in medicine dialogues were calculated using descriptive statistics, and the statistical significance of observed differences across pharmacies was analyzed using odds ratios (OR). Considerable differences between the pharmacies were identified. Differences exist in how often pharmacy staff attempts to encourage customers to participate in medication dialogues and how often they succeed. The pharmacies serving the most customers per day were the most successful. A possible link between a low number of refill customers offered counseling and 'success rate' was identified. The pharmacies showed considerable variation in attempts to engage customers in medication dialogues at the counter and success in doing so. The reasons for the identified patterns are unclear.

In this talk I wish to briefly review the experience we have obtained at the Rutherford Appleton Laboratory over the past decade in the adaptation of MWPC (multiwire proportional counter) technology to diagnostic imaging applications in medicine. A cursory glance at the history of science and technology quickly shows the often intimate and mutually beneficial relationship between ''pure'' science (and scientists) and practical applications. The following talk traces some of the principal features of the situation which have been brought to my attention in the course of the last decade. (author)

Intracranial hypertension (idiopathic-IIH and secondary) is a potentially treatable condition. Although various factors such as female gender and obesity, certain drugs have been implicated as risk factors for IIH, there remains a lack of clarity in the exact causal-effect relationship. In India, self-medication by obtaining drugs over the counter due to lack of adequate drug regulation and ignorance of the public is a very common practice with a potential for severe adverse effects. We present a case of a young lady who has developed intracranial hypertension possibly due to self-medication with steroids and cyproheptadine, obtained over the counter.

Development of new portable radiation counters for promotion of better understanding of radiation by the public

Tanabe, Hiroshi

1995-01-01

This study aims to promote the correct understanding of radiation to the public. All the questions asked by participants at forums held in Aomori, where commercial nuclear fuel cycle facilities are planned, were studied. More than half of these questions were concerned about radiation hazards. Measurements, using radiation counters at the meeting, provided the most effective means of explanation about radiation hazards to the public. For this purpose, portable β- and α-ray counters, being able to detect small amounts of radioactive substances around us, were developed. Each new counter is easily handled, is light-weight (about 10-20% that of domestic survey meters) and inexpensive (about 20-25% the price). The methods used to explain radiation with both counters have been also studied. This explanation has provided the public with a better understanding of the nature and hazards of radiation on human health than the former methods using textbooks. (author)

"Just Advil": Harm reduction and identity construction in the consumption of over-the-counter medication for chronic pain.

Science.gov (United States)

Eaves, Emery R

2015-12-01

Direct-to-consumer marketing has sparked ongoing debate concerning whether ads empower consumers to be agents of their own care or shift greater control to the pharmaceutical industry. Ads for over-the-counter (OTC) medications in particular portend to offer simple, harmless solutions for meeting the demands of social life. Rather than join the longstanding debate between consumer agency and social control in pharmaceutical advertising, I approach self-medication with over-the-counter (OTC) analgesics using Harm Reduction as a framework. From this perspective, consumption of OTC analgesics by chronic pain sufferers is a means of seeking some level of relief while also avoiding the stigma associated with prescription pain medication. Qualitative methods are used to analyze data from two sources: (1) semi-structured qualitative interviews with 95 participants in a trial examining the effectiveness of Traditional Chinese Medicine for Temporomandibular Disorders (TMD) from 2006 to 2011 in Tucson, AZ and Portland, OR; and (2) print, online, and television advertisements for three major brands of OTC pain medication. Participants described their use of OTC medications as minimal, responsible, and justified by the severity of their pain. OTC medication advertising, while ostensibly ambiguous and targeting all forms of pain, effectively lends support to the consumption of these medications as part of the self-projects of chronic pain sufferers, allowing them to reconcile conflicting demands for pain relief while being stoic and maintaining a positive moral identity. Describing OTC medication as "just over-the-counter" or "not real pain medication," sufferers engage in ideological harm reduction, distinguishing themselves from "those people who like taking pain medication" while still seeking relief. Justifying one's use of OTC medication as minimal and "normal," regardless of intake, avoids association with the addictive potential of prescription pain medications and

The internal nasal valve is the narrowest part of the nasal airway and a common site of inspiratory collapse and obstruction of nasal airflow. Over-the-counter mechanical nasal dilators are an alternative to surgical intervention that attempts to improve airflow through the internal nasal valve. To determine the efficacy of over-the-counter mechanical nasal dilators and classify these products by mechanism. A database of 33 available over-the-counter mechanical nasal dilators was generated via a PubMed search as well as an internet search via Amazon.com and Google, conducted from April 1, 2013, through December 31, 2015. Products determined to be unavailable or discontinued were excluded from the database. Of the devices examined in published literature, efficacy was based on objective measures, such as measured airflow, the cross-sectional area of the nasal valve, and changes in resistance. Measures of reported sleep quality or patient perception were excluded. An analysis of each product's mechanism revealed 4 broad classes: external nasal dilator strips, nasal stents, nasal clips, and septal stimulators. A review demonstrated 5 studies supporting the use of external nasal dilator strips, 4 studies supporting the use of nasal clips, 1 study supporting the use of nasal stents, and no studies supporting the use of septal stimulators. Our findings suggest that external nasal dilator strips and nasal clips effectively relieve obstruction of the internal nasal valve and may be an alternative to surgical intervention in some patients.

Elemental composition of herbal medicines sold over-the-counter in Sao Paulo city, Brazil

International Nuclear Information System (INIS)

Moreira, H.S.

2011-01-01

In Brazil, the use of herbal medicines is very popular due to its immense flora, cultural aspects and to the popular belief that herbs, which are of natural origin, are safe and without undesirable side effects. Aside from that public interest in natural therapies, the use of herbal medicines has increased expressively due to the high cost of synthetic medicines. In this study, elemental compositions of herbal medicines from the species Ginseng, Ginkgo biloba, Centella asiatica, Mulberry and Aloe vera supplied by different suppliers were evaluated by neutron activation analysis. The concentrations of As, Ba, Br, Ca, Cl, Co, Cr, Cs, Fe, Hf, K, Mg, Mn, Na, Rb, Sb, Sc, Th, Zn and some lanthanides were determined in these samples. Comparisons made between the results indicated differences in their elemental contents depending on the plant species, origins of the samples and the age of the leaves. The results also showed that the herbal medicines contain elements such as Ca, Co, K, Fe, Mg and Zn known as essential to humans and for treatment and prevention of diseases. Toxic elements such as Hg, Cd and Cu were not detected. Elements As and Sb were detected in some samples but at very low concentrations at the μg kg -1 levels. Herbal medicine results were also compared to literature values. Biological certified reference material was analyzed for quality control of the analytical results. (author)

Phadtare, Sangita; Abali, Emine; Brodsky, Barbara

2013-01-01

For successful delivery of basic science topics for health-professional students, it is critical to reduce apprehension and illustrate relevance to clinical settings and everyday life. At the beginning of the Biochemistry course for Physician Assistants, a team-based assignment was designed to develop an understanding of the mechanism of action, effectiveness, and toxicity of five common over the counter (OTC) drugs and dietary supplements, and place these familiar medicines in a political and historical context. The objectives of this exercise were to stimulate interest in biochemistry; to provide basic information on enzymes and enzyme inhibitors related to these drugs to be expanded upon later in the course; and to encourage active and interactive learning. Teams of five students were formed, and each student was given an information sheet on aspirin, alpha-galactosidase, orlistat, dextromethorphan, or simvastatin, a low dose statin, which was previously available without prescription at pharmacies in the UK. After each member of the team acquired information on one OTC drug/dietary supplement by reading an assigned information sheet, the team was asked to go through a series of questions, and then submit answers to a quiz as a group. A high rate of success on the quiz, an overwhelmingly positive response on formal course evaluations, and enthusiastic exchanges during class suggested this team-based session accomplished its goals.

Majeed, A; Grobler, S R; Moola, M H; Oberholzer, T G

2011-10-01

This in vitro study evaluated the effect of four over-the-counter tooth-whitening products on enamel microhardness. Fifty enamel blocks were prepared from extracted human molar teeth. The enamel surfaces were polished up to 1200 grit fineness and the specimens randomly divided into five groups. Enamel blocks were exposed to: Rapid White (n=10); Absolute White (n=10); Speed White (n=10) and White Glo (n=10) whitening products, according to the manufacturers' instructions. As control, ten enamel blocks were kept in artificial saliva at 37 degrees C without any treatment. Microhardness values were obtained before exposure (baseline) and after 1, 7 and 14-day treatment periods using a digital hardness tester with a Vickers diamond indenter. Data were analysed using Wilcoxon Signed Rank Sum Test, one-way ANOVA and Tukey-Kramer Multiple Comparison Test (penamel microhardness. Speed White increased the microhardness of enamel, while White Glo and artificial saliva had no effect on hardness. Over-the-counter tooth-whitening products might decrease enamel microhardness depending on the type of product.

2012-01-01

Challenges to engage pharmacy customers in medicine dialogues at the counter have been identified comprising a new and extended clinical role for pharmacists in the health care system. This article seeks to expand understanding of factors involved in successful interaction at the pharmacy counter between customers and pharmacy staff to develop their relationship further. Practical challenges to customer encounters experienced by community pharmacists are discussed using theory from the field of mainly inter-relational communication and particular studies on pharmacy communication. Preconceived expectation of customers, the type of question asked by pharmacy staff, and differences in perception of illness and medicines between staff and customers are discussed. Both staff and customer influence the outcome of attempts by pharmacy staff to engage customers in dialogue about their medicine use through a complex mechanism of interaction. It is recommended that practitioners and researchers begin to distinguish, both theoretically and practically, between the content of a conversation and the underlying relationship when exploring and further developing the therapeutic relationship between pharmacy personnel and customers.

Correlates of Abusing and Misusing Over-the-Counter Pain Relievers Among Adult Population of Wrocław (Poland).

Science.gov (United States)

Wójta-Kempa, Monika; Krzyżanowski, Dominik M

2016-01-01

Almost 90% of households in Poland buy medicines on their own initiative. The most popular OTC medicines bought by Polish consumers are painkillers and non-steroid-anti-inflammatory drugs. The aim of this article was to recognize and describe the most important predictive factors of the abuse and misuse of over-the-counter pain relievers among adults in Wrocław (Poland). The groups of users were selected and described. Some examples of misuse were analyzed. Three hundred eighty six adult inhabitants of Wrocław took part in the survey. The quota sample was representative referring to the most important socio-demographic factors (sex and median age). Almost 91% of participants declare taking OTC pain relievers, and 1.3% of them are their daily users. Only 6.2% of adult inhabitants of Wrocław never take OTC pain relievers. The category of "heavy users" embraces 11% of participants. The most important risk factors of overusing OTC pain relievers are sex (female), age over 55 years and the low health status. Only half of participants read the box label regularly and 25% of users admit they have modified recommended doses. Over 60% shortened recommended intervals between doses and 16% took two or more different pain medications (containing different substances). The non-medical purposes of using OTC pain relievers were: tiredness (7%), stressful situations (5.4%), and discomfort (18.4%). Some users take pain medications to cure hangovers (26%), or instead of the appropriate medicine (7%). About 20% take pain medications without a doctor's advice for longer than the recommended 3 days, and 10% never consult taking such medications with doctors. Pain should be treated aggressively and successfully, especially among chronically ill patients. We should monitor the consumption of OTC pain relievers and limit their current excessively supply and high availability.

Lee, Mina; Whitehill King, Karen; Reid, Leonard N

2015-04-01

Using a model developed from the research literature, the authors compared consumers' attitudinal and behavioral responses to direct-to-consumer prescription drug advertising (DCTA) and over-the-counter nonprescription drug advertising (OTCA) of drugs. Adults 18 years of age and older who had taken any prescription drugs in the past 6 months completed online survey questionnaires. Variables measured included demographics (age, gender, race, education, and income), health-related characteristics (health status, prescription and over-the-counter drug use, health consciousness, and involvement with prescription or over-the-counter drugs), perceived amount of attention and exposure to DTCA and OTCA, attitudinal outcomes (skepticism toward DTCA/OTCA and attitude toward DTCA/OTCA), and behavioral outcomes triggered by DTCA and OTCA. The findings indicate that exposure to drug advertising is one of the most significant predictors of attitudinal and behavioral outcomes. Some audience factors such as health status, involvement with drugs, health consciousness, drug use, income, and age also were differentially associated with consumer responses to drug advertising.

Esmay, J B; Wertheimer, A I

1979-01-01

The authors review the extent of the use of nonprescription drugs as well as possible variables influencing such consumption. Various studies indicate that age, sex, personality characteristics, perceptions of health status, socioeconomic factors, parental example, and pharmacists all play parts in determining over-the-counter (OTC) drug utilization. Several sources express concern about the inaccessibility of accurate OTC drug information to the consumer. Indeed, even the FDA has occasional difficulty obtaining reliable facts on both the numbers and formulae of such products. Several studies indicate that consumers acquire information about their home remedies through advertising, friends and relatives, physicians, pharmacists, and product labels. By far the most influential of these is advertising, and much concern has been voiced over consumers' unquestioning faith in drug ads. Examples are cited of deceptive, inaccurate, and unfair advertising practices used by some OTC drug manufacturers. The pros and cons of the "drug-oriented society" theory are discussed, including an analysis of its underlying origins. Testing of the safety and efficacy of nonrescription remedies has proved to be controversial, especially when considering the ramifications of the placebo effect. Different surveys report widespread misuse of OTC's by consumers through overuse, taking several drugs concurrently, and using home remedies to treat potentially serious diseases.

Background: Over-the-counter (OTC)-drugs are available without a doctor’s prescription. Whereas this is convenient for consumers, it also makes consumers responsible for appropriate and safe use. European countries differ considerably when it comes to the availability of OTC-drugs. In the Netherlands, the availability of OTC-drugs changed in 2007. A limited number of OTC-drugs can now be sold outside pharmacies and chemistries, mainly in supermarkets. This had led to a discussion on whether c...

Full Text Available The Food and Drug Administration (FDA warned against administering over-the-counter cough and cold medicines to children under 2. This study evaluated whether experienced parents show poorer adherence to the FDA warning, as safe experiences are predicted to reduce the impact of warnings, and how adherence can be improved. Participants included 218 American parents (mean age: 29.98 (SD = 6.16, 82.9% female with children age 2 or less who were aware of the FDA warning. We compared adherence among experienced (N=142; with other children > age 2 and inexperienced parents (N=76; only children 2 or yess. We also evaluated potential moderating variables (amount of warning-related information received, prevalence of side effects, trust in the FDA, frequency of coughs and colds, trust in drug packaging and quantified the impact of amount of information. Logistic regression assessed the ability of experience alone, and experience combined with amount of information, to predict adherence. 53.3% of inexperienced but 28.4\\% of experienced parents were adherent (p = 0.0003. The groups did not differ on potential moderating variables. Adherence was 39.5% among experienced parents receiving ``a lot of information'', but 15.4% for those receiving less (p = 0.002; amount of information did not affect adherence in inexperienced parents (p = 0.22 but uniquely predicted adherence compared to a model with experience alone (p = 0.0005. Experienced parents were also less likely to mistrust drug packaging (p = 0.03. Targeting FDA information to experienced parents, particularly via drug packaging, may improve their adherence.

We examine the announcement period of stock returns for 179 over-the-counter (OTC) firms that issue common stock to reduce nonconvertible debt. We find that small OTC firms experience returns that are significantly more negative than large OTC firms. Regression tests reveal that firm size is a significant factor in accounting for stock returns. Other tests establish as firm size a dominant effect. Our support for a firm size effect is consistent with a differential information effect given th...

2014-01-01

We investigated color change, gingival irritation, and tooth sensitivity in patients undergoing at-home vital tooth bleaching with a novel over-the-counter bleaching tray system. Tooth color shade in anterior teeth, supragingival plaque and gingivitis in Ramfjord teeth, as well as visual assessment of teeth gingival tissues and mucosa were evaluated in-office prior to treatment, after two consecutive applications of the 9% hydrogen peroxide bleaching product, after eight applications (10 minutes/day for 3 days at home), and after ten applications (50 minutes exposure over 5 days). Color stability was evaluated at 3 months after completing the treatment regimen. Over-the-counter bleaching products can be used by the patient at home without dentist supervision, but are frequently associated with gingival irritation and tooth sensitivity despite low concentrations of peroxide agents. Our investigations showed that the treatment is tolerable and safe with a low incidence of adverse effects. Any adverse effects associated with use of the whitening gel and tray are temporary, easily controlled, and often disappear within minutes of treatment. Statistical analysis revealed significant improvement in teeth whitening following treatment (mean color change of seven shades) and at three months after treatment. PMID:24591847

Analysis of the phenomenon of over-the-counter drug abuse and not controlled herbs trade by polish adolescents: Part I

Full Text Available The phenomenon of stupefying by the use of available over-the-counter drugs (OTC among adolescents is an essential problem in both Poland and throughout the world. Popular analgesics, cold medicine and antihistamines contain psychedelic substances, such as dextromethorphan (DXM, pseudoephedrine/ephedrine, codeine (methylmorphine, dimenhydrinate, paracetamol (acetaminophren and others. Cases of fatal addiction to dextromethorphan, one of the active substances contained in medicines, e.g., the common cold, have been reported. The test results cited by the authors clearly indicate that the use of OTC drugs, whose turnover is not controlled is a domain of females. The extent of use of drugs not prescribed by a doctor has remained for many years at a constant level. The most common poisonings with OTC drugs are caused by those that affect the respiratory system or exert analgesic or antipyretic effects. They are also used in attempted suicides, especially among females. Analyzing poisonings caused by OTC medications their seasonality has been observed. Their number increases during spring–autumn. A territorial differentiation in areas of OTC drug trade in terms of their quantities, with the predominance of southern regions is also noted. Intoxication with psychoactive substances causes the deterioration of relations between young people. In the reviewed studies there is no detailed information on the composition of non-prescription medicines. Moreover, young people have easy access to mushroom fungi, growing in nearby forests and meadows that may have hallucinogenic effects and are available in pharmacies and on the Internet.

Deaths due to abuse of dextromethorphan sold over-the-counter in Pakistan

Directory of Open Access Journals (Sweden)

Humera Shafi

2016-09-01

Full Text Available Dextromethorphan is the most commonly used over-the-counter anti-tussive and expectorant medicine at therapeutic doses. Due to easy availability, euphoric high and hallucinogenic effects at larger doses, dextromethorphan popularity amongst the drug abusers is growing day by day. It is often mixed with alcohol, opiates, cannabinoids or other drugs of abuse for recreational purposes despite their lethal synergistic effects. More than 50 deaths were reported the first time in Pakistan after consuming cough syrups containing dextromethorphan, manufactured by two local pharmaceutical industries. All deceased had the history of drug abuse. We report the deaths of nineteen males, ages ranged from 17 to 45 years, in two major cities of Pakistan who purposefully ingested large doses of dextromethorphan for recreational purposes and died as a result of direct toxic effects of the drug. Toxicological analysis revealed high levels of dextromethorphan ranging from 7.3 to 41.7 mg/L in the peripheral blood, 4.2–92.6 mg/kg in the liver and 9.9–349.6 mg/L in the gastric content by high performance liquid chromatography. The dextromethorphan concentrations in all subjects significantly exceeded the therapeutic range and were consistent with concentrations reported in other cases of dextromethorphan abuse and toxicity. Besides dextromethorphan other drugs of abuse like cannabinoids, opiates, benzodiazepines, ethanol and chlorpheniramine were also detected. The cause of death was determined to be acute dextromethorphan intoxication with lethal synergistic effect of other co-ingested drugs of abuse. The deaths resulted in the prosecution of all individuals involved in manufacturing, distribution or sale of the cough syrup.

Pharmaceutical counseling: Between evidence-based medicine and profits.

Science.gov (United States)

Egorova, S N; Akhmetova, T

2015-01-01

pharmaceutical counseling standards: Article 1.1 "Code of Ethics of the pharmaceutical worker of Russia" states: "The main task of the professional activity of the pharmaceutical worker - protection of human health", Article 1.3 states that a pharmaceutical worker must take professional decisions solely in the interests of a patient [1]. However, the pharmacy is a trade organization, thus as a retailer the pharmacy is directly interested in making profits and increasing sales of pharmaceutical products, including non-prescription medicines. Moreover, while the clinical medicine is monitored for unjustified prescribing and measures are being taken to prevent polypharmacy, for a pharmacist the growing sales of over-the-counter drugs, active promotion of dietary supplements, homeopathic medicines, medical devices, and, consequently, an increase of financial indicators (particularly "average purchase size") - all are characteristics of success [2].Rational use of over-the-counter medicines requires introduction of pharmaceutical counseling standards (pharmaceutical care) according to symptoms - major reasons to visit a pharmacy as part of responsible self-medication (cold, sore throat, headache, diarrhea, etc.). Standards of pharmaceutical counseling should be objective, reliable and up-to-date and contain recommendations for the rational use of over-the-counter drugs as well as indications requiring treatment to the doctor. Standardization of pharmaceutical counseling in terms of Evidence-based Pharmacy would enhance the efficiency, safety and cost-effectiveness of over-the-counter medicines.Currently, the lack of clinical component in the higher pharmaceutical education and the lack of approved standards of pharmaceutical counseling lead to the introduction of cross-selling technologies (which are broadly applied in other areas of trade, for example, the offer of a boot-polish during the sale of shoes) to the pharmaceutical practice [2, 3]. However, drugs belong to a special group

Tobin, Claire L; Dobbin, Malcolm; McAvoy, Brian

2013-10-01

Analysis of the policy response by Australia's National Drugs and Poisons Schedule Committee (NDPSC) and comparison with recommendations by expert advisory committees in New Zealand and the United Kingdom. Analysis of public policy documents of relevant regulatory authorities was conducted. Data were extracted regarding changes to over-the-counter (OTC) codeine analgesic scheduling, indications, maximum unit dose, maximum daily dose, maximum pack size, warning labels, consumer medicine information and advertising. Where available, public submissions and other issues considered by the committees and rationale for their recommendations were recorded and thematically analysed. Expert advisory committees in Australia, NZ and the UK defined the policy problem of OTC codeine misuse and harm as small relative to total use and responded by restricting availability. Pharmacist supervision was required at the point-of-sale and pack sizes were reduced to short-term use. Comparison with recommendations by expert advisory committees in NZ and the UK suggests the NDPSC's actions in response to OTC codeine misuse were appropriate given the available evidence of misuse and harm, but highlights opportunities to utilise additional regulatory levers. Framing policy problems as matters of public health in the context of limited evidence may support decision makers to implement cautionary incremental policy change. © 2013 The Authors.

Dissolution rates of over-the-counter painkillers: a comparison among formulations.

Science.gov (United States)

Alemanni, Matteo; Gatoulis, Sergio C; Voelker, Michael

2016-06-01

We wanted to compare the dissolution profile of several over-the-counter analgesics to understand whether the different formulation techniques employed to enhance absorption were associated with variations in the dissolution rate, a parameter known to affect drug absorption. We considered 5 formulations currently marketed in Italy: aspirin tablets (Aspirina Dolore e Infiammazione®), ibuprofen tablets and liquid capsules (Moment®), ibuprofen lysine tablets (Nurofenimmedia®) and dexketoprofen trometamol tablets (Enantyum®). Dissolution tests were performed according to the current USP/NF monograph dissolution procedure. Drug dissolution was evaluated at 1, 3, 6, 15, and 30 minutes since the start of the test. Dissolution was evaluated at three different pH: 1.2, 4.5 and 6.8. Every test was repeated 12 times. The aspirin formulation was by far the most rapid dissolving formulation, among those tested, with more than 80% of the tablet dissolved at 6 minutes for every pH considered. At pH 1.2 and 4.5, only the dexketoprofen formulation was able to reach the dissolution level of aspirin at 30 minutes, but had lower levels of dissolution at the previous time points. Instead, at pH 6.8, most of the formulations approached aspirin dissolution level, but only after 15 minutes. Ibuprofen capsules had the slowest kinetics, with a lag phase the first 6 minutes. Different formulation strategies can lead to great differences in the dissolution rates even among drugs of the same class, suggesting that enhancements in the formulation of painkillers can lead to improvements in drug absorption, and thus in the onset of analgesia.

Full Text Available Background. Over-the-counter medications are widely available in pharmacies Their safety profile, however, does not extend to pregnant women. Accordingly, there should be educational programs developed for pregnant women to protect them from the harms of the side effects. Aim. This study was planned and designed with the aim of exploring the awareness and assessing the usage of OTC medications among pregnant women in Sharjah, UAE. Method. A cross-sectional survey using a self-administered questionnaire. Results. More than three-quarters (75.7% reported that they are familiar with the term “over-the-counter drugs.” Interestingly, 40% of the respondents reported that they took OTC drugs during pregnancy, and the majority (94.2% agreed with the survey statement “not all OTC medications are safe to be taken during pregnancy.” Constipation was the most frequent side effect that most of the participants reported during the study period. Folic acid (36%, calcium (28.6%, and iron (35.1% were the most common supplements used by the pregnant women responding. Conclusion. The reported 40% usage of OTC medications among pregnant women in this study is worrisome and calls for the need to educate, counsel, and increase awareness among pregnant women regarding the dangers of OTC drugs usage while pregnant in Sharjah, UAE.

Over-the-Counter Hearing Aids: A Lost Decade for Change

2015-01-01

Full Text Available Background. Hearing aids sold directly to consumers in retail stores or through the internet, without individual prescription by audiological professionals, are termed over-the-counter (OTC devices. This study aimed to determine whether there was any change in the electroacoustic characteristics of OTC devices compared to research carried out a decade earlier. The previous results indicated that most OTC devices were low-frequency-emphasis devices and were unsuitable for elderly people with presbycusis, who were likely to be the major consumers of these products. Methods. Ten OTC devices were selected and their electroacoustic performance was measured. Appropriate clients for the OTC devices were derived, using four linear prescription formulae, and OTC suitability for elderly persons with presbycusis was investigated. Results. OTC electroacoustic characteristics were similar to those in the earlier study. Most OTC devices were not acoustically appropriate for potential consumers with presbycusis. Although several of the devices could match prescriptive targets for individuals with presbycusis, their poor electroacoustic performance—including ineffective volume control function, high equivalent input noise, and irregular frequency response—may override their potential benefit. Conclusion. The low-cost OTC devices were generally not suitable for the main consumers of these products, and there has been little improvement in the appropriateness of these devices over the past decade.

Aikin, Kathryn J; Sullivan, Helen W; O'Donoghue, Amie C; Betts, Kevin R

2016-01-01

Information on the effects of promotional offers in direct-to-consumer prescription drug ads is limited. In two studies, we examined the effect of promotional offers (e.g., money-back guarantee) and ad type (creating prescription and over-the-counter drug ads by varying the presence of benefit and risk information). We found little effect of promotional offers. Adding benefit (risk) information to the ad increased consumers' knowledge of the benefit (risk) information and their efficacy (risk) perceptions. In most cases, adding risk information to an ad with benefit information increased risk knowledge and perceptions without decreasing benefit knowledge or perceptions.

Una estrategia para mejorar la utilización de medicamentos a largo plazo es modificar la percepción que tiene la población en general con respecto a la necesidad y uso de los medicamentos para curar sus dolencias.In this study we examined the 100 over-the-counter drugs that were most widely sold in Brazil from June 1992 to June 1993. We excluded 23 food products that were classified as medicinal. The sample, which included 77 drugs, was representative of about 67% of all sales in monetary value, and 76.8% of all units sold of the different classes of over-the-counter drugs. The anatomical-therapeutic-chemical (ATC system was used to classify the various drugs; each class of drugs was also graded according to a scale of its intrinsic value, taking into account effectiveness and risks. Most classes of drugs (91% showed "little intrinsic value" (that is, were of questionable or no value, of relative value, or unacceptable, and 70% were fixed-dose combinations. Only 10 classes of drugs were included in the Ministry of Health's National Drug List, and four appeared in WHO's list of essential drugs. The therapeutic classes to which the drugs belonged were, in descending order of frequency, for the digestive tract, skin, genitourinary system, musculo-skeletal system, central nervous system, parasitic diseases, respiratory tract, and sensory system. The therapeutic subgroup that commanded the highest sales was that of the non-opiate analgesics and antipyretics. Our results confirm the hypothesis that over-the-counter drugs in Brazil are of poor therapeutic quality and that the use of many such drugs is a source of unnecessary expense for the population. Some of them should not be accessible to individuals who lack current knowledge of their side effects, since 25% of all cases of poisoning in the country are related to self-medication.

Kohli, Erol; Buller, Allison

2013-02-01

US consumers spend more than $20 billion/year on over-the-counter (OTC) drugs. Although generic and brand name OTC drugs share the same active ingredients and undergo the same rigorous Food and Drug Administration approval process, brand name formulations continue to lead the OTC drug market with a higher market share. There is a limited amount of publicly available information regarding consumer perceptions and awareness about generic and brand name OTC drugs. The main objective of this research was to understand what factors influence US consumers to purchase generic versus brand name OTC drugs. The researchers used a 20-question, self-administered, multiple-choice survey to collect data on the factors influencing consumers' preferences for generic versus brand name OTC drugs. Results revealed that the single most influential factor for participants when purchasing OTC drugs was lower cost. Although economic factors play an important role in influencing consumers to choose generic formulations, a variety of other factors including advertisements, duration of the OTC effectiveness, severity of sickness, preferable form of OTC medication, safety of the OTC, relief of multiple symptoms, and preferred company will persuade others to pay more for brand name drugs. Ultimately, increased awareness and use of generic OTC drugs may result in substantial cost savings for consumers.

2017-01-01

Full Text Available Over-the-counter (OTC opioid abuse, including codeine, has been a growing problem around the world. Although the majority of the abusers use it for recreational purposes, many become dependent on it after having used it a medication for pain or cough. We present a case of codeine dependence where the initial prescribed use had been as a cough medication, but the subsequent abuse of it occurred the following self-medication for premature ejaculation. There is growing need for awareness among doctors and pharmacists of OTC abuse of opioids and for preventive interventions such as restricting supply, audit of pharmacies, training pharmacists, and counter staff and dispensing knowledge about proper use of opioid-containing medications to patients.

Applications of phytochemical and in vitro techniques for reducing over-harvesting of medicinal and pesticidal plants and generating income for the rural poor.

Sarasan, Viswambharan; Kite, Geoffrey C; Sileshi, Gudeta W; Stevenson, Philip C

2011-07-01

Plants provide medicine and pest control resources for millions of poor people world-wide. Widespread harvesting of medicinal and pesticidal plants puts pressure on natural populations, thus severely compromising their contribution to the income and well-being of traders and consumers. The development of in vitro propagation techniques appropriate for developing countries will provide a robust platform for effective propagation and cultivation of endangered plants. This review focuses on advances in the application of phytochemical and in vitro tools to identify and rapidly propagate medicinal and pesticidal plants. Problems of over-harvesting can be alleviated and ex situ cultivation in agroforestry systems can be facilitated through improving seed germination, in vitro cloning and the use of mycorrhizal fungi. We also present a case for effective use of phytochemical analyses for the accurate identification of elite materials from wild stands and validation of the desired quality in order to counter loss of efficacy in the long run through selection, propagation or ex situ management in agroforestry systems. Future prospects are discussed in the context of medicinal activity screening, sustainable propagation, on-farm planting, management and utilization.

Older adults purchase and use over-the-counter (OTC) medications with potentially significant adverse effects. Some OTC medications, such as those with anticholinergic effects, are relatively contraindicated for use by older adults due to evidence of impaired cognition and other adverse effects. To inform the design of future OTC medication safety interventions for older adults, this study investigated consumers' decision making and behavior related to OTC medication purchasing and use, with a focus on OTC anticholinergic medications. The study had a cross-sectional design with multiple methods. A total of 84 adults participated in qualitative research interviews (n = 24), in-store shopper observations (n = 39), and laboratory-based simulated OTC shopping tasks (n = 21). Simulated shopping participants also rank-ordered eight factors on their importance for OTC decision making. Findings revealed that many participants had concerns about medication adverse effects, generally, but were not aware of age-related risk associated with the use of anticholinergic medications. Analyses produced a map of the workflow of OTC-related behavior and decision making as well as related barriers such as difficulty locating medications or comparing them to an alternative. Participants reported effectiveness, adverse effects or health risks, and price as most important to their OTC medication purchase and use decisions. A persona analysis identified two types of consumers: the habit follower, who frequently purchased OTC medications and considered them safe; and the deliberator, who was more likely to weigh their options and consider alternatives to OTC medications. A conceptual model of OTC medication purchase and use is presented. Drawing on study findings and behavioral theories, the model depicts dual processes for OTC medication decision making - habit-based and deliberation-based - as well as the antecedents and consequences of decision making. This model suggests

Sterile syringe access is critical to HIV prevention efforts targeting injection drug users (IDUs) but some pharmacies do not sell syringes over-the-counter (OTC) even where such sales are legal. We conducted a pharmacy survey in Tijuana, Mexico (where OTC sales are legal) to characterize attitudes toward syringe sales and to explore support for expanding pharmacy-based HIV prevention efforts. Of 203 respondents, 28% supported OTC syringe sales to IDUs and 74% said their pharmacy required a prescription for at least some syringe sales. Support for OTC syringe sales was independently associated with selling OTC syringes, understanding the role of sterile syringes in HIV prevention, and recognizing pharmacies as an important health resource for IDUs. Most respondents supported an expanded role for pharmacies in HIV prevention, exclusive of OTC syringe sales. Our study provides information for developing interventions to promote OTC syringe sales and expanding pharmacy-based distribution of HIV-related information and resources.

Use of the over-the-counter drugs by adults and an assessment of the impact of advertisements on consumers

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.

Evidence-based treatment of frequent heartburn: the benefits and limitations of over-the-counter medications.

McRorie, Johnson W; Gibb, Roger D; Miner, Philip B

This review summarizes the pharmacological effects of over-the-counter (OTC) heartburn drugs, and the implications for treating frequent heartburn. PubMed and SCOPUS were searched across all years to identify well-controlled, randomized clinical studies that assessed mechanism of action and efficacy. Antacids can transiently neutralize acid in the esophagus, but do not significantly affect gastric pH or prevent subsequent heartburn episodes. Histamine-2 receptor antagonists (H2 RAs) rapidly develop tolerance with repeat dosing, and exhibit an analgesic effect that may provide heartburn relief while leaving the esophagus exposed to acid. Proton pump inhibitors (PPIs) provide a sustained inhibition of gastric acid production, and are superior to antacids and H2 RAs for control of gastric acid and treatment of frequent heartburn. When recommending therapies for frequent heartburn, it is of particular importance to understand the strengths and weaknesses of available OTC medications. Antacids and H2 RAs are not recommended for treatment of frequent heartburn, while OTC PPIs are both indicated for, and effective for, treatment of frequent heartburn. A PPI dose of 20 mg is optimal for empiric treatment of frequent heartburn, and consistent with the 2013 treatment guidelines established by the American College of Gastroenterology (ACG) for treatment with a minimum effective dose. ©2014 The Author(s) ©2014 American Association of Nurse Practitioners.

Over-the-Counter and Out-of-Control: Legal Strategies to Protect Youths From Abusing Products for Weight Control

Science.gov (United States)

Taylor, Lisa M.; Austin, S. Bryn

2013-01-01

Abuse of widely available, over-the-counter drugs and supplements such as laxatives and diet pills for weight control by youths is well documented in the epidemiological literature. Many such products are not medically recommended for healthy weight control or are especially susceptible to abuse, and their misuse can result in serious health consequences. We analyzed the government’s role in regulating these products to protect public health. We examined federal and state regulatory authority, and referred to international examples to inform our analysis. Several legal interventions are indicated to protect youths, including increased warnings and restrictions on access through behind-the-counter placement or age verification. We suggest future directions for governments internationally to address this pervasive public health problem. PMID:23237149

What is legal medicine--are legal and forensic medicine the same?

Science.gov (United States)

Beran, Roy G

2010-04-01

Some consider the terms "forensic" and "legal" medicine to be synonymous but this is counter to the title of the Faculty of Forensic and Legal Medicine or the dual strands for progression to fellowship of the Australian College of Legal Medicine. The paper examines a very brief historical background to legal medicine and develops a definition of the strands thereof, namely legal and forensic medicine. It demonstrates that the two are different components of the application of medical knowledge upon the legal system. Legal medicine has greater relevance to civil and tort law, impacting upon patient care, whereas forensic medicine relates to criminal law and damage to, or by, patients.

Full Text Available Abstract Background Over the counter sale of antibiotics is a global problem and it is increasingly recognized as a source of antibiotic misuse and is believed to increase treatment costs, adverse effects of treatment and emergence of resistance. The increasing trend of over the counter sale of antibiotics in Ethiopia calls for exploration of why such dispensing is practiced. This study aims to explore reasons for over the counter sale of antibiotics in the community pharmacies of Addis Ababa, Ethiopia. Methods A phenomenological qualitative study was conducted in five randomly selected community pharmacies of Addis Ababa. One pharmacy professional from each pharmacy were interviewed at the spot using semi-structured, open-ended interview checklist. Besides, observation of professionals’ dispensing practice was made for at least one hour in the same community pharmacies using an observation checklist. Findings were categorized into specific themes that were developed following the objectives. This was facilitated by use of OpenCode 3.6 software. Results All participants pointed out that antibiotics were frequently dispensed without prescription and contend that the trend of such dispensing has been increasing. The findings indicated that the nonprescription sales of antibiotics were common for Amoxicillin, Ciprofloxacin and Cotrimoxazole. The poor, less educated and younger groups of the population were reported to frequently request antibiotics without prescription. The main reasons for nonprescription sale of antibiotics by pharmacy professionals were found to be related to pharmacy owner’s influence to maximize revenue, customer’s pressure, weak regulatory mechanism and professional conflicts of interest. Conclusion The study shows that nonprescription sale of antibiotics was common practice at least in Addis Ababa. The main reasons for this malpractice were the need to maximize revenue and weak regulatory mechanism. Hence, strong

A new charge measurement method, time over threshold (TOT), has been used in some gas detectors lately. Here TOT is studied for TOF system, made of plastic scintillator counter, which can simplify the electronics of the system. The signal characteristics are measured and analyzed with a high quality oscilloscope, including noise, pedestal, signal amplitude, total charge, rise time and the correlation between them. The TOT and charge are related and can be fitted by some empirical formula. The charge measurement resolution by TOT is given and this will help the design of TOF electronics. (authors)

Strobelt, W.

1976-01-01

The layout of the whole-body counter at the institute for biophysics of the Giessen radiation centre is decribed. With suitable collimators, the whole-body counter may be used to determine the radioactivity in human and animal organs. The shielding and the measuring and waiting rooms for the patients are described with regard to their technical details. The whole-body counting system enables the radioactivity and the retention of various radioisotopes (e.g. 58 Co-vitamin B 12 , 40 K, 54 Mn, 137 Co, 131 J, 22 Na) to be measured. The estimation of the radiation exposure due to different types of examinations in nuclear medicine, in terms of the critical organs for each type of examination, is very accurate with this counting device.

2015-01-01

Background Interest is growing in moving oral contraceptives over-the-counter (OTC), although concerns exist about whether women would continue to get preventive health screening. Study Design We recruited cohorts of US-resident women who obtained oral contraceptives from US family planning clinics (n=532) and OTC from pharmacies in Mexico (n=514) and interviewed them four times over 9 months. Based on self-reports of having a Pap smear within 3 years or ever having had a pelvic exam, clinical breast exam and testing for sexually transmitted infections (STIs), we assessed the prevalence of preventive screening using Poisson regression models. Results The prevalence of screening was high for both groups (>88% for Pap smear, pelvic exam and clinical breast exam and >71% for STI screening), while the prevalence ratios for screening were higher for clinic users, even after multivariable adjustment. Conclusions Results suggest that most women would obtain reproductive health preventive screening if oral contraceptives were available OTC, and also highlight the need to improve access to preventive screening for all low-income women.

Position sensitive proportional counters as focal plane detectors

International Nuclear Information System (INIS)

Ford, J.L.C. Jr.

1979-01-01

The rise time and charge division techniques for position decoding with RC-line proportional counters are reviewed. The advantages that these detectors offer as focal plane counters for nuclear spectroscopy performed with magnetic spectrographs are discussed. The theory of operation of proportional counters as position sensing devices is summarized, as well as practical aspects affecting their application. Factors limiting the position and energy resolutions obtainable with a focal plane proportional counter are evaluated and measured position and energy loss values are presented for comparison. Detector systems capable of the multiparameter measurements required for particle identification, background suppression and ray-tracing are described in order to illustrate the wide applicability of proportional counters within complex focal plane systems. Examples of the use of these counters other than with magnetic spectrographs are given in order to demonstrate their usefulness in not only nuclear physics but also in fields such as solid state physics, biology, and medicine. The influence of the new focal plane detector systems on future magnetic spectrograph designs is discussed. (Auth.)

Over-the-counter drugs block heart accumulation of MIBG

1985-01-01

Previous work in the authors' laboratory using chemically sympathectomized animals showed that > 50% of meta-iodobenzyl-guanidine (MIBG) in the heart is localized in adrenergic nerves. In the present study, commonly used drugs known to alter the uptake and/or release of norepinephrine by adrenergic neurons have been evaluated for their effect on the biodistribution of MIBG. Pseudoephedrine (Sudafed), phenylpropanolamine (Dexatrim) and phenylephrine (Neosynephrine) were administered (5 mg/kg, i.p.) to rats; amphetamine was also evaluated (0.8mg/kg, i.p.). Thirty minutes later I-125-MIBG (0.2-0.4 Ci/mm) was injected i.v.; animals (N=3) were sacrificed 2 h following radiotracer. Compared to controls (N = 3), drug pretreatments resulted in large decreases in radiotracer concentration in adrenergic-rich tissues such as left atrium, left ventricle, spleen and parotid glands. Pseudoephedrine caused decreases (%) of 78, 57, 48 and 35 in the four tissues, respectively. Each of the four drugs caused a greater decrease in I-125-MIBG concentration in the left atrium than in the left ventricle. Comparative studies using H-3-norepinephrine are in progress. Entex, a nasal decongestant containing both phenylephrine and phenylpropanolamine, markedly diminished the heart and salivary gland accumulation of I-123-MIBG in a normal male volunteer. These preliminary studies suggest that commonly used sympathomimetic agents, including some over-the-counter preparations, decrease the accumulation of MIBG in adrenergic neurons. These results also suggest that patients should be carefully screened for drug usage prior to MIBG scintigraphy of the heart

2016-05-01

With the recent merger of the American Osteopathic Association (AOA) and the Accreditation Council for Graduate Medical Education (ACGME) a heightened pressure for publication may become evident. Our objective was to determine whether there was a gap in the type of both medical degree designation and advanced degree designation among authorship in three United States-based academic emergency medicine journals. We reviewed the Journal of Emergency Medicine, Academic Emergency Medicine and Annals of Emergency Medicine for the type of degree designation that the first and senior authors had obtained for the years 1995, 2000, 2005, 2010 and 2014. A total of 2.48% of all authors held a degree in osteopathic medicine. Osteopathic physician first authors contributed to 3.26% of all publications while osteopathic physician senior authors contributed 1.53%. No statistical trend could be established for the years studied for osteopathic physicians. However, we noted an overall trend for increased publication for allopathic senior authors (p=0.001), allopathic first authors with a dual degree (p=0.003) and allopathic senior authors with a dual degree (p=0.005). For each journal studied, no statistical trend could be established for osteopathic first or senior authors but a trend was noted for allopathic first and senior authors in the Journal of Emergency Medicine (p-value=0.020 and 0.006). Of those with dual degrees, osteopathic physicians were in the minority with 1.85% of osteopathic first authors and 0.60% of osteopathic senior authors attaining a dual degree. No statistical trend could be established for increased dual degree publications for osteopathic physicians over the study period, nor could a statistical trend be established for any of the journals studied. Very few osteopathic physicians have published in the Journal of Emergency Medicine, Academic Emergency Medicine or Annals of Emergency Medicine over the last two decades. Despite a trend for increased

No Understanding, No Consent: The Case Against Alternative Medicine.

Science.gov (United States)

Shahvisi, Arianne

2016-02-01

The demand for informed consent in clinical medicine is usually justified on the basis that it promotes patient autonomy. In this article I argue that the most effective way to promote autonomy is to improve patient understanding in order to reduce the epistemic disparity between patient and medical professional. Informed consent therefore derives its moral value from its capacity to reduce inequalities of power as they derive from epistemic inequalities. So in order for a patient to have given informed consent, she must understand the treatment. I take this to mean that she has sufficient knowledge of its causal mechanisms and has accepted the explanations in which the treatment is implicated. If this interpretation of informed consent is correct, it is unethical for medical professionals to offer or endorse 'alternative medicine' treatments, for which there is no known causal mechanism, for if they do, they may end up widening the epistemic disparity. In this way, informed consent may be understood as an effective way of ruling out particular treatments in order to improve patient autonomy and maintain trust in the medical profession. © 2016 John Wiley & Sons Ltd.

Non-Imaging Detectors and Counters. Chapter 10

Energy Technology Data Exchange (ETDEWEB)

Zanzonico, P. B. [Department of Medical Physics, Memorial Sloan Kettering Cancer Center, New York (United States)

2014-12-15

Historically, nuclear medicine has been largely an imaging based specialty, employing such diverse and increasingly sophisticated modalities as rectilinear scanning, (planar) gamma camera imaging, single photon emission computed tomography (SPECT) and positron emission tomography (PET). Non-imaging radiation detection, however, remains an essential component of nuclear medicine. This chapter reviews the operating principles, performance, applications and quality control (QC) of the various non-imaging radiation detection and measurement devices used in nuclear medicine, including survey meters, dose calibrators, well counters, intra-operative probes and organ uptake probes. Related topics, including the basics of radiation detection, statistics of nuclear counting, electronics, generic instrumentation performance parameters and nuclear medicine imaging devices, are reviewed in depth in other chapters of this book.

Cleland, Kelly; Bass, Jamie; Doci, Florida; Foster, Angel M.

2016-01-01

Introduction After years of complex regulatory changes, levonorgestrel emergency contraception (LNG EC) is now approved for unrestricted sale in the US. Timely access to EC pills is critical because they are more likely to work the sooner they are taken. This study assesses whether LNG EC is sold in accordance with current Food and Drug Administration regulations. Methods We distributed an online questionnaire through an EC-focused listserv for reproductive health professionals, asking data collectors to visit local stores and document product names, price, over-the-counter (OTC) shelf availability, and misinformation about age restrictions. We used Chi-square analysis to assess bivariate associations and t-tests and Wilcoxon rank-sum tests to determine differences in means. Results We collected information about 220 stores. The majority (65%) stocked EC on OTC shelves, although only 22% of these displayed it without a locked security enclosure. Chain pharmacies were more likely to shelf-stock EC than independent pharmacies (77% vs 5%; p=0.000), but variation existed among stores within the same chain. Among stores that were asked, 40% incorrectly reported an age restriction for non-prescription purchase of LNG EC, while 95% correctly reported that men can buy LNG EC. The average price of branded and generic LNG EC was $49.64 and $40.05, respectively. Conclusion Changes in the regulatory status of LNG EC have resulted in widespread confusion about how EC can be sold, and its high price contributes to access barriers. Retailers should ensure that consumers can access LNG EC quickly and easily by stocking the product on OTC shelves and educating staff about current regulations. PMID:27682018

To determine the pharmacologic activity of over-the-counter (OTC) thyroid preparations. In vitro analysis and a prospective, crossover study in vivo. Tertiary care center. Two healthy adult volunteers. Three OTC preparations (Thyrotrophin PMG [bovine thyroid PMG extract], Thyro Forte [thyroid lymphogland concentrate with synergistic complex], and Thyro Complex [thyroid lyophilized gland concentrate with synergistic complex]) were analyzed in vitro. Volunteers were administered two times the manufacturer's maximum recommended daily dose of either Thyrotrophin PMG or Thyro Forte for one week, washed out for four to five weeks, and crossed over to receive the opposite tablet preparation for an additional week. The triiodothyronine (T3) and thyroxine (T4) contents of OTC preparations were measured by HPLC. Vital signs, serum total and free T4, total T3, thyroid stimulating hormone, thyroxine binding globulin, thyroglobulin, and general chemistry tests (including glucose and cholesterol) were monitored before, during, and between administration of the products. HPLC analysis of the three OTC preparations showed no T4 but did show possible T3 in two of these products. We found no definite clinical or laboratory evidence of thyroid hormone excess with either product. Healthcare professionals should advise against the use of these scientifically unsound and relatively expensive OTC thyroid preparations, of which the therapeutic efficacy is unknown.

In the last two decades there has been a world wide increase in the number of drugs that are being switched from the prescription-only category to non-prescription categories. In Israel, until recently, non-prescription medicines were only permitted to be sold by a pharmacist in pharmacies. In May 2005, following amendments to the law, several non-prescription medicines which were previously sold under a pharmacist's supervision, were reclassified as general-sales-list (GSL) medicines and permitted to be displayed and sold directly off the shelves in pharmacies and in other places such as grocery stores and petrol stations. To study the change in the patterns of consumption of non-prescription drugs in Israel two years after the reform began. A representative sample of the population of Israel was chosen and interviews were conducted at two time points: before the reform commenced and two years after the beginning of the reform. Statistical processing was performed in order to examine the changes in patterns of consumption of non-prescription drugs in Israel between these two time points. In both surveys it was found that: approximately 70% of the Israeli public buys non-prescription medicines; 70% of the people interviewed said that they had been aware of the reform, but of these, about 75% continued buying nonprescription drugs from the pharmacist while 21% bought medicines off the shelves at the pharmacy and 4% purchased medications at grocery stores. The most common reasons for buying medicines off the shelves without a pharmacist were earlier knowLedge about the medication, convenience and availabiLity when the pharmacies were closed. An insignificant difference was observed for the purchase of non-prescription drugs from the different types of pharmacies: the health maintenance organizations (HMO) pharmacies continue to be the leading pharmacies from which the public purchased their non-prescription medicines, white there was a slight increase in the

Advertising health: the case for counter-ads.

Science.gov (United States)

Dorfman, L; Wallack, L

1993-01-01

Public service advertisements have been used by many in hopes of "selling" good health behaviors. But selling good behavior--even if it could be done more effectively--is not the best goal for using mass media to prevent health problems. Personal behavior is only part of what determines health status. Social conditions and the physical environment are important determinants of health that are usually ignored by health promotion advertising. Public service advertising may be doing more harm than good if it is diverting attention from more effective socially based health promotion strategies. Counter-ads are one communications strategy that could be used to promote a broader responsibility for rectifying health problems. In the tradition of advocacy advertising directly promoting policy rather than products, counter-ads promote views consistent with a public health perspective. Counter-ads set the agenda for health issues, conferring status on policy-oriented strategies for addressing health problems. The primary purpose of counter-ads is to challenge the dominant view that public health problems reflect personal health habits. They are controversial because they place health issues in a social and political context. Advertising strategies for health promotion range over a spectrum from individually oriented public service advertising to socially oriented counter-advertising. The recent anti-tobacco campaign from the California Department of Health Services represents advertisements across the spectrum. Counter-ads that focus on a politically controversial definition for health problems are an appropriate and necessary alternative to public service advertising. PMID:8265756

Clinical utility of marketing terms used for over-the-counter dermatologic products.

Boozalis, Emily; Patel, Shivani

2018-05-08

Cosmetic products are commonly marketed using dermatologic terms such as 'hypoallergenic', 'non-comedogenic', 'fragrance-free', etc. The clinical relevance of these claims can be confusing to both patients and clinicians. A systematic review was performed via a PubMed search of published articles from January 1985 to October 2017 to further describe and elucidate the clinical utility of a predefined list of common dermatologic terms used by pharmaceutical companies to market over-the-counter products. The terms 'fragrance-free', 'hypoallergenic', 'non-comedogenic', and 'oil-free' on cosmetic product labels are not regulated by any governing body and provide varied clinical utility. Products labeled as having 'natural ingredients' are not necessarily safer or less irritating to patients with atopy or a history of allergic contact dermatitis. Despite the increasing popularity of 'paraben-free' cosmetics, parabens are safe for patients in the quantities used in cosmetic products and can be safely used in patients who do not exhibit contact dermatitis to this preservative. A working knowledge of common cosmetic ingredients may help dermatologists to counsel patients on which products to avoid for their specific dermatologic conditions.

Over-the-counter human immunodeficiency virus self-test kits: time to explore their use for men who have sex with men in Brazil

Directory of Open Access Journals (Sweden)

Sheri A. Lippman

2014-05-01

Full Text Available Increasing access and frequency of human immunodeficiency virus testing are critical to stemming the epidemic. In Brazil's concentrated epidemic, human immunodeficiency virus prevalence in the men who have sex with men/transgender population far exceeds that in the general population, but testing rates fall below what is needed to ensure early detection and treatment. Over-the-counter human immunodeficiency virus self-testing kits, now available in stores in the U.S., have enormous potential to increase testing access and frequency and to facilitate early detection and treatment. With the advent of human immunodeficiency virus self-testing upon us, it is timely to engage the scientific community, government, and civil society in a dialog around how to best utilize this technology in Brazil. We summarize recent research on over-the-counter testing among men who have sex with men, raise potential questions and challenges to using self-tests, suggest implementation strategies, and outline a research agenda moving forward.

COUNTER-PUNISHMENT, COMMUNICATION AND COOPERATION AMONG PARTNERS

Directory of Open Access Journals (Sweden)

Full Text Available We study how communication affects cooperation in an experimental public goods environment with punishment and counter-punishment opportunities. Participants interacted over thirty rounds in fixed groups with fixed identifiers that allowed them to trace other group members’ behavior over time. The two dimensions of communication we study are asking for a specific contribution level and having to express oneself when choosing to counter-punish. We conduct four experimental treatments, all involving a contribution stage, a punishment stage and a counter-punishment stage in each round. In the first treatment communication is not possible at any of the stages. The second treatment allows participants to ask for a contribution level at the punishment stage and in the third treatment participants are required to send a message if they decide to counter-punishment. The fourth combines the two communication channels of the second and third treatments. We find that the three treatments involving communication at any of the two relevant stages lead to significantly higher contributions than the baseline treatment. We find no difference between the three treatments with communication. We also relate our results to previous results from treatments without counter-punishment opportunities and do not find that the presence of counter-punishment leads to lower cooperation level. The overall pattern of results shows that given fixed identifiers the key factor is the presence of communication. Whenever communication is possible contributions and earnings are higher than when it is not, regardless of counter-punishment opportunities.

Counter-Productive Counter-Terrorism. How is the dysfunctional discourse of Prevent failing to restrain radicalisation?

Directory of Open Access Journals (Sweden)

Lauren Powell

2016-09-01

Full Text Available This paper explores why the Prevent strand of the UK Government’s counter-terrorism strategy, CONTEST, is failing to achieve success in reducing radicalisation of young Muslims. By refusing to engage with extremists, and denying ‘extreme’ ideas a platform for expression, this paper will explain how the importance of cultural-linguistic epistemologies, and their role in extremism, has been overlooked. Rather than striving to understand how socio-political factors influence one’s reading of religious doctrines or interpretation of ideology, Prevent understands ideology to be the core radicalising agent, used by influential figures who can exploit the grievances of the vulnerable. The problematic repercussions of this will be addressed throughout, highlighting the various, and extensive, criticisms that Prevent has faced from academics, practitioners and commentators – primarily that it is counter-productive. The importance of the post-9/11 neoconservative paradigm in underpinning Prevent will be explained, but a Neo-Weberian approach, as a better lens through which to understand radicalisation, will be proposed, to ultimately trump the simplistic, yet currently dominant, ‘Conveyor Belt’ theory. Based on this, recommendations are made for an improved Prevent, rooted in the notion that radicalisation, extremism, or terrorism cannot be prevented, without knowing the motives, the views, and the assumptions of the radicals, the extremists, and those vulnerable to engaging with them.

Medicine, morality, and the market.

Science.gov (United States)

Owen, D

1984-07-07

In extracts from a lecture given at McGill University, the author describes the rise of a marketing or corporate ethos in medicine, stemming from economic constraints and the demographic pressures of aging populations in the U.S., Canada, and the United Kingdom. To counter the trend to corporate rather than public policy making in medicine, he advocates a holistic approach to health care, a revival of interest in preventive health, and encouragement of the self-help movement. Owen calls for a reorientation of medical attitudes so that traditional moral values of medicine present a "counterweight to the mechanistic, technological, cost-effectiveness of the market place."

Needle counter

Fujita, Yuzo

1977-01-01

Needle counter had been devised by Geiger about 60 years ago before the present GM counter appeared. It is suitable for the detection of weak radiation because it is limited in effective volume, if the background due to mainly cosmic ray is proportional to the effective volume of the counter. Recently the very low β detector having a needle counter as the main detector has been developed. It showed highly excellent performance in the measurements of small area samples, about ten times sensitive as compared with other detectors. The counter is installed in the very low radiation measuring well at Nokogiriyama, Chiba Prefecture, using a NaI scintillator as its guard counter. D. H. Wilkinson first treated a gas amplification counter theoretically and quantitatively. The authors have obtained good results in the comparison with the experiments of the counter using a generalized form of Wilkinson theory. The findings obtained through this study seem to be applicable to the electrode arrangement which is important for the counter design. It was found that the excellent rise time of induced pulses in a gas amplification counter was achieved in larger amplification factor and smaller convolution effect. In the detection of charged particles with small obstructing capability such as γ ray, faster rise time and higher pulses can be obtained with needle counters than wire counters. (Wakatsuki, Y.)

Limited effectiveness of over-the-counter plant preparations used for the treatment of urinary tract infections as inhibitors of the urease activity from Staphylococcus saprophyticus.

Deutch, C E

Urease is a key virulence factor for the Gram-positive urinary tract pathogen Staphylococcus saprophyticus and a potential target for antimicrobial therapy. The enzyme from S. saprophyticus is unusual in that it does not contain cysteine at the active site. The aims of this study were to test 14 over-the-counter plant preparations as inhibitors of this urease and to determine whether they can prevent the increase in pH that normally occurs in bacterial cultures containing urea. Urease activity was measured colorimetrically by the formation of ammonium ions. The green tea and Uva-Ursi preparations reduced urease activity in a soluble extract of S. saprophyticus by more than 75%. Two herbal mixtures were weakly inhibitory and reduced activity by about 25%, but the other products had little or no effect. The green tea and Uva-Ursi extracts also inhibited urease activity in whole cells by more than 75%. One of the herbal products (WishGarden UTI) showed some inhibition of urease activity but the other (UTI Clear) did not. The green tea and Uva-Ursi preparations prevented the increase in pH that normally occurs when S. saprophyticus is grown in an artificial urine medium, but this was due primarily to bacterial death. The WishGarden UTI preparation could partially delay the pH increase while allowing some cells to remain viable. These results indicate that only a few of the commercially available over-the-counter plant preparations commonly used for the treatment of urinary tract infections (UTIs) can inhibit the urease activity from S. saprophyticus. While over-the-counter plant preparations may be considered an alternative to traditional antibiotics for the treatment of UTIs, they should be used with caution and a product should be matched to the properties of the virulence factors of the bacterial pathogen involved. © 2017 The Society for Applied Microbiology.

Precision medicine, an approach for development of the future medicine technologies

Iraj Nabipour

2016-04-01

Full Text Available Precision medicine is an approach in medicine that takes into account individual differences in people's genes, environments, and lifestyle. This field of medicine redefines our understanding of disease onset and progression, treatment response, and health outcomes through the more precise measurement of molecular, environmental, and behavioral factors that contribute to health and disease. Undoubtedly, the advances in omics technologies including genomics, data collection and storage, computational analysis, and mobile health applications over the last decade produced significant progress for precision medicine. In fact, precision medicine is a platform for the growth of personalized medicine, wearable biosensors, mobile health, computational sciences, genomic singularity, and other omics technologies. In the pathway of precision medicine, mathematics and computational sciences will be revolutionized to overcome the challenges in Big Data. By the birth of precision medicine, novel therapeutic strategies for chronic complex diseases such as cardiovascular disease and cancers would be designed in Systems Medicine.

Full Text Available Advertising of the Over-the-counter drugs is a growing segment. Our research aims to identify the main factors involved in making decisions for the purchase of OTC drugs and to identify what are the ways of informing consumers for this process. To test the hypotheses, a number of statistical tools such as factor analysis, Shapiro-Wilk and Mann-Whitney U tests have been used. The analyzed factors were: (A doctor’s choice , (b former own experience, (c pharmacist’s advice, (d information stated on the prospectus, (e opinion of people who bought that drug, (f opinion of colleagues, friends, relatives, (g price, (h brand, manufacturer, (i information from advertising, (j quality of advertising. For our analysis, we focused on two main populations: students and employed educated people. The main conclusion of this paper is that recent exposure to OTC advertising is likely to change both related behaviors and decision grids.

The correct and rational use of medications can have a positive direct impact on disease outcomes, as well on the utilization of the health system resources. Unfortunately, 50% of the patients do not take their medications as prescribed, largely due to lack of patients' understanding of their medical condition, as well as the lack of reliable medicine information.There are multiple strategies implemented in many countries to tackle this challenge including: disease awareness campaigns (DAC) to raise the public awareness to specific diseases, direct-to-consumer advertisement (DTCA) to raise the public awareness to prescription medicines, specific treatments and over-the-counter (OTC) products to improve the accessibility of patients to specific medicines.Prior to 2013, the Israeli policy prohibited prescribing medication advertising and prevented the flow of information from pharmaceutical companies to the patient. In the last five years, the Pharmaceutical division in the Israeli Ministry of Health, as part of the "empowering the patient" agenda, has taken new innovative approaches to raise public awareness to diseases, medications and appropriate usage, as well as promotion of information to improve patient adherence to the prescribed medication.This paper elaborates on the aforementioned strategies implemented in developed countries, and specifically focuses on newly implemented strategies and regulations in Israel regarding pre- and post-prescription information, to improve patient appropriate utilization and adherence to medication.

A Model of Consumer Response to Over-the-Counter Drug Advertising: Antecedents and Influencing Factors.

Huh, Jisu; Delorme, Denise E; Reid, Leonard N

2016-01-01

Given the importance of over-the-counter (OTC) drugs in the health care marketplace and lack of systematic research on OTC drug advertising (OTCA) effects, this study tested a theory-based, product category-specific OTCA effects model. Structural equation modeling analysis of data for 1 OTC drug category, analgesics, supported the proposed model, explaining the OTCA effect process from key consumer antecedents to ad involvement, from ad involvement to ad attention, from ad attention to cognitive responses, then to affective/evaluative responses, leading to the final behavioral outcome. Several noteworthy patterns also emerged: (a) Product involvement was directly linked to ad attention, rather than exerting an indirect influence through ad involvement; (b) ad attention was significantly related to both cognitive and affective/evaluative responses to different degrees, with stronger links to cognitive responses; and (c) ad-prompted actions were influenced by both ad trust and ad attitude.

Kopp, M.K.; Borkowski, C.J.

1975-12-01

A new method was developed for encoding the position of individual photons, neutrons, or charged particles in proportional counters by using the distributed RC line characteristics of these counters. The signal processing is described and guidelines for the design and operation of these position sensitive proportional counters (PSPCs) are given. Using these guidelines, several prototypic PSPCs were constructed to improve the spatial resolution and shorten the signal processing time; for example, the intrinsic spatial uncertainty was reduced to 28 μ fwhm for alpha particles and 100 μ fwhm for low-energy x rays (2 to 6 keV). Also, the signal processing time was reduced to 0.6 μsec without seriously degrading the spatial resolution. These results have opened new fields of application of the RC position encoding method in imaging distributions of photons, charged particles, or neutrons in nuclear medicine, physics, and radiography

Losing the Plot: Narrative, Counter-Narrative and Violent Extremism

Directory of Open Access Journals (Sweden)

Andrew Glazzard

2017-05-01

Full Text Available Counter-terrorist practitioners and policy makers appear to be very interested in narrative. They often describe the worldview of violent Islamist groups and movements as the ‘jihadi narrative’, while their efforts to confront terrorist propaganda are usually labelled as ‘counter-narrative’ or ‘alternative narrative’. However, while the counter-narrative approach has gained widespread acceptance in governments, think-tanks and civil society organisations, it is built on very shaky theoretical and empirical foundations. Some valuable theoretical contributions to the study of violent extremist narrative have been made by psychologists in particular, but there is one discipline which is conspicuous by its absence from the field: literary studies. This paper makes a case for the value of studying violent extremist narratives as narratives in the literary sense. By employing the tools and techniques of literary criticism, violent extremist communication can be revealed as not only potentially persuasive, but also creative and aesthetically appealing: terrorists inspire their followers, they don’t merely persuade them. Understanding the creative sources of this inspiration is vital if counter-narrative is to succeed in presenting an alternative to the propaganda of violent extremist groups.

There has been an increased emphasis on improving the level of evidence used as the basis for clinical treatment decisions. Several journals now require a statement of the level of evidence as a basic gauge of the study's strength. To review the levels of evidence in published articles in the clinical sports medicine literature and to determine if there has been an improvement in the levels of evidence published over the past 15 years. Systematic review. All articles from the years 1995, 2000, 2005, and 2010 in The American Journal of Sports Medicine (AJSM), Arthroscopy, and sports medicine-related articles from The Journal of Bone and Joint Surgery-American (JBJS-A) were analyzed. Articles were categorized by type and ranked for level of evidence according to guidelines from the Centre for Evidence-Based Medicine. Excluded were animal, cadaveric, and basic science articles; editorials; surveys; special topics; letters to the editor; and correspondence. Statistical analysis was performed with chi-square. A total of 1580 articles over the 4 periods met the inclusion criteria. The percentage of level 1 and 2 studies increased from 6.8% to 12.6%, 22.9%, and 23.5%, respectively (P studies decreased from 78.9% to 72.4%, 63.9%, and 53.0% (P studies (4.1%, 5.1%, 28.2%, 27.8%; P studies all showed significant increases in level 1 and 2 studies over time (P studies published in the sports medicine literature over the past 15 years, particularly in JBJS-A and AJSM. The largest increase was seen in diagnostic studies, while therapeutic and prognostic studies demonstrated modest improvement. The emphasis on increasing levels of evidence to guide treatment decisions for sports medicine patients may be taking effect. © 2014 The Author(s).

Easy access to effective over-the-counter (OTC) treatments allows self-management of some conditions, however inappropriate or incorrect supply or use of OTC medicines can cause harm. Pharmacy personnel should support consumers in their health-seeking behaviour by utilising effective communication skills underpinned by clinical knowledge. To identify interventions targeted towards improving communication between consumers and pharmacy personnel during OTC consultations in the community pharmacy setting. Systematic review and narrative analysis. Databases searched were MEDLINE, EMBASE, Psycinfo, Cochrane Central Register and Cochrane Database of Systematic Reviews for literature published between 2000 and 30 October 2014, as well as reference lists of included articles. The search was re-run on 18 January 2016 and 25 September 2017 to maximise the currency. Two reviewers independently screened retrieved articles for inclusion, assessed study quality and extracted data. Full publications of intervention studies were included. Participants were community pharmacy personnel and/or consumers involved in OTC consultations. Interventions which aimed to improve communication during OTC consultations in the community pharmacy setting were included if they involved a direct measurable communication outcome. Studies reporting attitudes and measures not quantifiable were excluded. The protocol was published on Prospero Database of Systematic Reviews. Of 4978 records identified, 11 studies met inclusion criteria. Interventions evaluated were: face-to-face training sessions (n = 10); role-plays (n = 9); a software decision making program (n = 1); and simulated patient (SP) visits followed by immediate feedback (n = 1). Outcomes were measured using: SP methodology (n = 10) and a survey (n = 1), with most (n = 10) reporting a level of improvement in some communication behaviours.

Counter-responses as organizers in adolescent analysis and therapy.

Science.gov (United States)

Richmond, M Barrie

2004-01-01

The author introduces Counter-response as a phenomological term to replace theory-burdened terms like counter-transference, counter-identification, and counter-resistance. He discusses the analyst's use of self (drawing on the comparison with Winnicott's use of the object) in processing the expectable destabilizing counter-reactions that occur in working therapeutically with disturbed adolescents and their parents. Further; he discusses the counter-reaction to the patient's narrative, acting-out, and how re-enactments can serve as an organizer for understanding the patient's inner life when the analyst formulates his/her counter-response. Emphasis is placed on the therapist forming his or her own narrative with the adolescent that takes into account the evoked counter-reaction. For this purpose, the author recommends the use of a combined counter-response and metaphor-orienting perspective to acknowledge and work with the denial, illusions, reversal of perspective, and catastrophic anxieties experienced with these adolescents. The counter-response perspective permits the emergence of the disturbed adolescent's novel narrative; however, since these experiences can be destabilizing or disruptive, the author also recommends the use of a personal metaphor to anticipate the reluctance to examining, processing, and formulating the analyst's dysphoric counter-reaction. With the use of the counter-response, the analyst's therapeutic ideal is to achieve a more optimal balance between using accepted narrative theories and exploring novel enactment experiences. His swimming metaphor stratagem is designed to keep the analyst in these difficult encounters.

Over the last centuries, there were many important discoveries in medicine that were crucial for gaining a better understanding of several physiological processes. Molecular modelling techniques are powerful tools that have been successfully used to analyse and interface medicinal chemistry studies with electrochemical experimental results. This special combination can help to comprehend medicinal chemistry problems, such as predicting biological activity and understanding drug action mechanisms. Electrochemistry has provided better comprehension of biological reactions and, as a result of many technological improvements, the combination of electrochemical techniques and biosensors has become an appealing choice for pharmaceutical and biomedical analyses. Therefore, this review will briefly outline the present scope and future advances related to the integration of electrochemical and medicinal chemistry approaches based on various applications from recent studies.

Radke, Brian R

2018-03-01

Canadian Animal Health Institute (CAHI) data are used for provincial, national, and international comparisons of Canadian animal antimicrobial use. The objectives of this paper were to: i) use CAHI and British Columbia (BC) antimicrobial distribution data to group BC antimicrobial sales into the following BC retail distribution channels: over-the-counter retail outlets, livestock and poultry feed mills, aquaculture feed mills, livestock and poultry veterinarians, and companion animal veterinarians; and ii) to validate the CAHI BC distribution data and BC's antimicrobial distribution data from 2012 to 2014. Annual total antimicrobial distribution and distribution by antimicrobial class were presented for each distribution channel. The distribution of medically important antimicrobials for production animals was validated, the distribution of ionophores was not. A lack of data precluded any attempt to validate the distribution of antimicrobials for companion animals. Each distribution channel typically experienced substantial fluctuations in total antimicrobial use and use by antibiotic class at least once over the 3-year period. The validated data are useful for evidence-based analysis of a proposed Canadian policy requiring a veterinary prescription for all medically important antimicrobials.

Despite major advances in understanding the pathophysiology of mitochondrial diseases, clinical management of these conditions remains largely supportive, and no effective treatment is available. We therefore assumed that the burden of disease combined with the lack of adequate treatment leaves open a big market for complementary and alternative medicine use. The objective of this study was to evaluate the use and perceived effectiveness of complementary and alternative medicine in children and adults with genetically proven mitochondrial disease. The reported use was surprisingly high, with 88% of children and 91% of adults having used some kind of complementary and alternative medicine in the last 2 years. Also, the mean cost of these treatments was impressive, being 489/year for children and 359/year for adult patients. Over-the-counter remedies (e.g., food supplements, homeopathy) and self-help techniques (e.g., Reiki, yoga) were the most frequently used complementary and alternative therapies in our cohort: 54% of children and 60% of adults reported the various complementary and alternative medicine therapies to be effective. Given the fact that currently no effective treatment exists, further research toward the different therapies is needed, as our study clearly demonstrates that such therapies are highly sought after by affected patients.

Hypercalcemia, hypervitaminosis A and 3-epi-25-OH-D3 levels after consumption of an "over the counter" vitamin D remedy. a case report.

2012-06-01

Intoxication from vitamin D supplements has been rarely reported but, nowadays, it occurs more frequently. 3-epi-25-OH-D(3) is highly prevalent in adults and it is considered of biological relevance. We report a case of vitamin D toxicity with hypercalcemia, acute renal failure and hypervitaminosis A after consuming an over-the-counter vitamin D supplement. Our data suggest that the contribution of 3-epi-25-OH-D(3) is not altered during vitamin D toxicity, although the serum levels of 25-OH-D(3) and 3-epi-25-OH-D(3) may display a different rate of clearance. The patient also displayed hypervitaminosis A unrelated to diet, possibly caused by renal failure related to the hypercalcemia induced by vitamin D toxicity. Because of the increasing use of over-the-counter vitamin D supplements and the potential iatrogenic hypercalcemia related to hypervitaminosis A, the present case highlights the importance of evaluating both the use of (non-) prescribed medication and vitamin A status during vitamin D toxicity.

Responding to Cyber Jihad: Towards an Effective Counter Narrative

Directory of Open Access Journals (Sweden)

Bibi van Ginkel

2015-03-01

Full Text Available “Who is in control of the narrative?” is the mantra that now echoes in the hallways of the EU’s headquarters in Brussels. Spurred in part by large-scale jihadist propaganda, approximately 20,000 people from 50 countries have joined the fight in Iraq and Syria. So far, authorities in their countries of origin have not been able to address the jihadist radicalisation messages transmitted via the internet and social media. Many new initiatives were recently announced, however, including the establishment of a European counter-narrative centre in Brussels. Research Fellow Dr. Bibi van Ginkel analyses the role of the internet and social media in processes of radicalisation. It offers an outline of the various aspects of the jihadist narrative, in order better to understand what message needs to be countered. The counter-actions against this cyber jihad can take different forms. Parallel to the way in which advertisement campaigns are tailored to sell products to a certain target group, strategic communication should take into account how a number of recurring elements play a role in the counter-messaging. The understanding of who the target group is, what jihadist narrative is used and how that message can be countered, who the credible messenger should be, and what medium can best be used to deliver the message are all relevant questions that can only be answered in a context-specific manner. The Research Paper concludes with several recommendations on how the recently announced new European counter-narrative centre can effectively contribute to the already diverse landscape of counter-narrative initiatives.

We measure, with an oscillograph method the global time that pass between the time that a particle in a determined region of the studied counter and the answer of the amplifier associated to the counter. This delay is composed of the latency time T l and the T q delay, that result from the rise time finished of the impulse and whose value depends of the sensitivity threshold of the amplifier. The selection of (cosmic) particles generating discharge in the studied counter is obtained thanks to a telescope of two meters in coincidence whose opening is limited by a group of four counters in anti-coincidence with the first. The meter is arranged so that the median plan of the telescope crosses to a variable distance d of his axial thread. The measures have been done for different securities of the distance d and of the over-voltage V s applied to the counter. The results show that the statistical distribution of the delays is more spread especially when d is bigger and V s more reduced. The average values of the observed delays vary of 7.10 -8 s for d = 0 and V s es = 200 V, to 90.10 -8 s for d = 1,9 cm and V s = 50 V. The mobility of an free electron within the gaseous mixture filling the counter under a pressure of 10 cm.Hg was found equal: (2,1 ±0,2).10 4 cm 2 .s -1 .V -1 . (author) [fr

The average American adult reads at an 8th-grade level. Discharge instructions written above this level might increase the risk of adverse outcomes for children as they transition from hospital to home. We conducted a cross-sectional study at a large urban academic children's hospital to describe readability levels, understandability scores, and completeness of written instructions given to families at hospital discharge. Two hundred charts for patients discharged from the hospital medicine service were randomly selected for review. Written discharge instructions were extracted and scored for readability (Fry Readability Scale [FRS]), understandability (Patient Education Materials Assessment Tool [PEMAT]), and completeness (5 criteria determined by consensus). Descriptive statistics enumerated the distribution of readability, understandability, and completeness of written discharge instructions. Of the patients included in the study, 51% were publicly insured. Median age was 3.1 years, and median length of stay was 2.0 days. The median readability score corresponded to a 10th-grade reading level (interquartile range, 8-12; range, 1-13). Median PEMAT score was 73% (interquartile range, 64%-82%; range, 45%-100%); 36% of instructions scored below 70%, correlating with suboptimal understandability. The diagnosis was described in only 33% of the instructions. Although explicit warning signs were listed in most instructions, 38% of the instructions did not include information on the person to contact if warning signs developed. Overall, the readability, understandability, and completeness of discharge instructions were subpar. Efforts to improve the content of discharge instructions may promote safe and effective transitions home. Journal of Hospital Medicine 2017;12:98-101. © 2017 Society of Hospital Medicine.

Evolutionary medicine--the quest for a better understanding of health, disease and prevention.

Clinical medicine has neglected the fact that the make-up of organs and body functions, as well as the human-specific repertoire of behaviors and defenses against pathogens or other potential dangers are the product of adaptation by natural and sexual selection. Even more, for many clinicians it does not seem straightforward to accept a role of evolution in the understanding of disease, let alone, treatment and prevention.Accordingly, this Editorial seeks to set the stage for an article collection that aims at dealing precisely with the question of why evolutionary aspects of health and disease are not only interesting, but necessary to improve clinical medicine.

Herbal medicines have been routinely employed all over the world dated back from the ancient time and have been identified by patients and physicians for their excellent therapeutic value as they have lower adverse effects when compared with the modern medicines. Phytotherapeutics requires a scientific technique to deliver the active herbal extract in a controlled manner to avoid repeated administration and increase patient compliance. This can be reached by fabricating a novel drug delivery systems (NDDS) for herbal components. NDDSs does not only decrease the repeated dose to overcome ineffectiveness, but also help to increase potency by decreasing toxicity and elevating drug bioavailability. Nano-sized DDS of herbal drugs have a potential application for improving the activity and countering the problems related to herbal medicines. Hence, application of nanocarriers as an NDDS in the traditional herbal medicine system is important to treat more chronic diseases like infectious endocarditis. Copyright © 2016 Elsevier Masson SAS.

Understanding support for complementary and alternative medicine in general populations: use and perceived efficacy.

Stoneman, Paul; Sturgis, Patrick; Allum, Nick

2013-09-01

Proponents of complementary and alternative medicine argue that these treatments can be used with great effect in addition to, and sometimes instead of, conventional medicine, a position which has drawn sustained opposition from those who advocate an evidence-based approach to the evaluation of treatment efficacy. Using recent survey data from the United Kingdom, this article seeks to establish a clearer understanding of the nature of the public's relationship with complementary and alternative medicine within the general population by focusing on beliefs about the perceived effectiveness of homeopathy, in addition to its reported use. Using recent data from the United Kingdom, we initially demonstrate that reported use and perceived effectiveness are far from coterminous and argue that for a proper understanding of the motivations underpinning public support of complementary and alternative medicine, consideration of both reported use and perceived effectiveness is necessary. We go on to demonstrate that although the profile of homeopathy users differs from those who support this form of medicine, neither outcome is dependent upon peoples' levels of knowledge about science. Instead, the results suggest a far greater explanatory role for need and concerns about conventional medicine.

Antibiotics over-consumption is a pandemic that has a tremendous cost on the overwhelmed healthcare system. The accessibility of antibiotics coupled with the misconception of public toward those drugs both of which implicated in the use and misuse of antibiotics. The aim of this study was to investigate the perception of the community toward antibiotics, its purpose and harmfulness, in addition to the accessibility of those drugs as over the counter and without prescriptions. We also investigated the behavior toward antibiotic prescriptions when perceived unnecessary. This is a cross-sectional study in Riyadh-Saudi Arabia based upon a structured self-administered questionnaire. The study included 473 individuals with a mean age of 27 years old. Forty eight percent (n=227) of the participants obtain antibiotics without prescriptions. Ninety two percent (n=208) of those noted pharmacist counseling as their method of acquisition. Self-prescription noted in 8.4% (n=19). Viral illnesses accounted for the highest percentage for seeking antibiotics in 35.5% (n=166) more commonly among females. Thirty one point eight percent (n=149) used antibiotics for analgesia while 13.7% (n=64) believed in their prophylactic use. We also noted that the prevalence of sharing antibiotics is 19.7%. The perceived unnecessary prescriptions uncovered 122 of the participants who reported throwing the prescribed antibiotics away after acquisition. Dispensing antibiotics without prescription is an issue that mandates a political intervention and implementation of the existing laws that prohibit dispensing without proper prescription. We advocate public health measures targeting both healthcare providers and the public on the use and misuse of antibiotics. Copyright © 2017 King Saud Bin Abdulaziz University for Health Sciences.

Following a large regulatory reform in 2009, which ended the state's pharmacy monopoly, non-pharmacy retailers in Sweden today sell certain over-the-counter (OTC) drugs. The aim of this study was to investigate consumer preferences regarding OTC drug retailers and the reasons for choosing a pharmacy versus non-pharmacy retailer. We conducted a web survey aimed at Swedish adults. Out of a stratified sample of 4058 persons, 2594 agreed to take part (48% women; mean age: 50.3 years). Questions related to OTC drug use, retailer choice and factors affecting the participants' preferences for OTC drug retailers. Logistic regression was conducted to analyse OTC drug use and reasons for retailer choice in relation to sex, age and education. Nine in ten participants reported OTC drug use in the 6 months prior to the study. For their last OTC purchase, 76% had gone to a pharmacy, 20% to a grocery shop and 4% to a convenience store, gas station or online. Geographic proximity, opening hours and product range were reported as the most important factors in retailer choice. Counselling by trained staff was important to 57% of participants. The end of the state's pharmacy monopoly and the increase in number of pharmacies seem to have impacted more on Swedish consumers' purchase behaviours compared with the deregulation of OTC drug sales.

Chaar, Betty; Kwong, Kenelm

2010-02-01

Direct-to-consumer advertising (DTCA) of over-the-counter or prescribed medicines is a highly controversial issue relating to public health care. Advocates highlight the advantages of DTCA in terms of patient awareness and autonomy. Opponents voice concerns about safety and patients' best interests. The views of physicians and consumers about DTCA have been widely investigated. There has been little research, however, in relation to pharmacists' experiences with DTCA and the impact of DTCA on pharmacy practice. The aim of this study was therefore to explore pharmacists' perceptions of DTCA in Australia and its impact on pharmacy practice. A semi-structured in-depth interview was conducted with a purposive convenience sample of retail pharmacists in Sydney, Australia. Interviews were recorded, transcribed ad verbatim and continued until data saturation. Emerging themes were extracted and analysed according to the grounded theory approach. Pharmacists participating in this study reported concern about potential harm to patient health and well-being as a result of the influence of DTCA. DTCA was seen to impede pharmacists in the discharge of their fundamental ethical responsibilities, leading to a strong sense of disempowerment. Pharmacists' gate-keeping role was challenged by DTCA encouraging consumers to self-medicate and inducing a range of drug-seeking behaviours. Although pharmacists acknowledged that DTCA may have a role in promoting patient autonomy, in practice DTCA compromised their role in safeguarding consumers from inappropriate use of medicines. This study highlighted that the impact of DTCA is not restricted to prescription medicines, but extended also to over-the-counter, pharmacist-only and other pharmacy-related products. Pharmacists perceived that DTCA disempowered them, compromising their role in safeguarding the community from inappropriate medicine use.

[Comparison in dissolution behavior of ethical and over-the counter scopolamine butylbromide].

Marketing authorization holders do not disclose any information on the pharmaceutical properties of over-the-counter drugs (OTC). When a drug is switched from a prescription drug to OTC, pharmacists can acquire that information from the corresponding ethical drug (ED) through the package insert, interview form, and so on. However, the pharmaceutical equivalence between ED and OTC is unclear. In this study, we examined the drug dissolution behavior of both ED and OTCs containing scopolamine butylbromide. Dissolution tests were performed by the paddle method using Japanese Pharmacopeia (JP) XV test fluids at pH 1.2, 4.0 and 6.8 and water based on the guidelines for bioequivalence studies of generic products. The dissolution profiles of OTCs differed significantly from ED showing a similarity factor (f2) value ranging from 8.9 to 42.9. Time until 85% dissolution ranged from 23 to 95 min and from 17 to 174 min at pH 1.2 and pH 6.8, respectively. Then JP XV disintegration tests were conducted to investigate differences in the disintegration process. The disintegration time of preparations showing delayed dissolution was prolonged compared to that of others, suggesting that the disintegration of the tablet or capsule is one of the important factors affecting the drug dissolution. These differences in the disintegration and drug dissolution might cause differences in the bioavailability of the drug. For patient safety, more detailed product information of OTCs should be supplied by the manufacturer, and not be assumed from that of corresponding ED.

Designing better medicines delivery in the UK National Health Services (NHS

P. John Clarkson

2009-11-01

Full Text Available Background: Prescribed medicines are delivered through a variety ofroutes to patients in the UK National Health Service (NHSand are regulated by a host of health and trade related policy and law. These ensure the efficient and safe supply of medicines of appropriate quality from the pharmaceutical manufacturer through to the end-user, the patient. However, persisting medication errors and therecent discovery of counter feit medicines in the bona fide supply chain have meant there are growing concerns aboutthe timely, accurate and safe supply of medicines in the NHS. Methods: This study undertakes a systems design approach to processmodelling and understanding three key supply routes fromthe manufacturer through to the patient, across bothprimary and secondary care. A systems design approachwas deployed to investigate complex interactions betweenprofessionals, products and processes to improve patient safety in collaboration with twenty five clinical and non-linical stakeholders across the supply chain and six enduser patients.Results: Several system process models were developed from the literature, field observations and alongside the interviewees. The results reveal that risk to medication safety is perceived as occurring most at the patient-end ofthe medicines supply chain: the pharmacy and the ward.There are differences observed in the responses ofinterviewees when they engage with system models.Conclusions: This paper reflects on the use of a systems design, a mainly engineering approach, to understanding a health care domain problem of medication errors. The approach provided an enhanced insight into the complex set of system factors and interactions involved in generating medication errors. This study is among the first to develop asystems-wide view of the medicines supply process ‘as-is’and identify opportunities for re-design to improve patient safety.

The counter-terrorist campus: Securitisation theory and university securitisation – Three Models

Directory of Open Access Journals (Sweden)

Liam Gearon

2017-02-01

Full Text Available With intensified threats to global security from international terrorism, universities have become a focus for security concerns and marked as locus of special interest for the monitoring of extremism and counter-terrorism efforts by intelligence agencies worldwide. Drawing on initiatives in the United Kingdom and United States, I re-frame three – covert, overt and covert–overt – intersections of education, security and intelligence studies as a theoretical milieu by which to understand such counter-terrorism efforts. Against the backdrop of new legislative guidance for universities in an era of global terrorism and counter-terrorism efforts by security and intelligence agencies and their Governments, and through a review of Open-Source security/intelligence concerning universities in the United Kingdom and the United States, I show how this interstitial (covert, overt and covert– overt complexity can be further understood by the overarching relationship between securitisation theory and university securitisation. An emergent securitised concept of university life is important because de facto it will potentially effect radical change upon the nature and purposes of the university itself. A current-day situation replete with anxiety and uncertainty, the article frames not only a sharply contested and still unfolding political agenda for universities but a challenge to the very nature and purposes of the university in the face of a potentially existential threat. Terrorism and counterterrorism, as manifest today, may well thus be altering the aims and purposes of the university in ways we as yet do not fully know or understand. This article advances that knowledge and understanding through a theoretical conceptualisation: the counter-terrorist campus.

Consumers are hesitant in choosing generic medications as they are under the assumption that they are not as safe nor effective as brand medications. However, pharmacists do have the education and training to know that this is not the case. The aim of this study was to determine pharmacists' preference of generic versus brand over-the-counter (OTC) medication for their personal use as self-treatment for various health symptoms. A prospective, cross sectional study was conducted on 553 licensed pharmacists who were presumed to have expertise in the use of generic and brand name OTC medications. In a single Southwestern state in the United States, from December 2014 to January 2015, a web-based questionnaire was sent to pharmacists to explore their preference of brand and generic medications based on various health symptoms. Thirty-one brand-generic medication pairs were used to identify which medication type pharmacists preferred when asked about nine health symptoms. Frequency counts of pharmacists' preference of a brand medication or a generic OTC medication overall and for each of the nine health symptoms were determined. Chi-squared analyses and one-way ANOVA were conducted to determine if there were any differences between the preferences of brand and generic OTC medications across each symptom. The study overall showed that pharmacists preferred generic OTC medications to brand OTC medications (62 to 5 %, respectively). Based on an 11-point rating scale, pharmacists were likely to take OTC generic medications (as their choice of self-treatment) when presented with health symptoms (mean = 7.32 ± 2.88). In addition, pharmacists chose generic OTC medications over brand medications regardless of health symptoms (p brand name OTC medications for self-treating a variety of health symptoms. These study findings support the theory that expertise affects preference for generic versus brand name OTC medications. This information can be used to provide

Full Text Available Background Packages leaflets (PLs are essential for the safe use and efficacy of medicines. Aims To quantify the opinion of users of medicines on PLs through the application of a self-administered Likert scale, taking into consideration subjects’ sociodemographic data. Methods Participants were enrolled from two Portuguese regions: urban/littoral (Lisbon and rural/interior (Centre. 503 participants were included: 53 per cent males, 45 per cent 12 years of schooling. A questionnaire was used to collect the sociodemographic data. A Likert scale was self-administered to rate the characteristics of 12 randomized PLs (6 from prescription medicines and 6 from over-the-counter medicines (August-December 2014. An invitation was send to several institutions (e.g., municipal councils. The inclusion criteria were: agreeing, be capable of reading/writing, and be more than 17 years old. Results In the Likert scores obtained, no significant differences were found related to region, sex, marital status, age group (≥65 years and other, and employment status of participants. By contrast, significant differences were found related to education (2=42.747; p 12 years of schooling, more regular reading habits (2 or more books/year, higher income and less frequent medicines use, showed a more negative global opinion on PLs. Conclusion Sociodemographic data are important to understand users’ opinion on PLs. It seems that more educated subjects are more demanding. A lower socio-economic status positively influenced the participants’ opinion, with subjects’ poorer education being a relevant factor in this population. A higher frequency of taking medicines also positively contributed to a better opinion, probably due to a greater familiarity with PLs.

Health care services offered to the public should be based on the best available evidence. We aimed to explore pharmacy tutors' and trainees' views on the importance of evidence when making decisions about over-the-counter (OTC) medicines and also to investigate whether the tutor influenced the trainee in practice. Following ethical approval and piloting, semi-structured interviews were conducted with pharmacy graduates (trainees) and pharmacist tutors. Transcribed interview data were entered into the NVivo software package (version 10), coded and analysed via thematic analysis. Twelve trainees (five males, seven females) and 11 tutors (five males, six females) participated. Main themes that emerged were (in)consistency and contradiction, confidence, acculturation, and continuation and perpetuation. Despite having an awareness of the importance and potential benefits, an evidence-based approach did not seem to be routinely or consistently implemented in practice. Confidence in products was largely derived from personal use and patient feedback. A lack of discussion about evidence was justified on the basis of not wanting to lessen patient confidence in requested product(s) or possibly negating the placebo effect. Trainees became acculturated to 'real-life' practice; university teaching and evidence was deemed less relevant than meeting customer expectations. The tutor's actions were mirrored by their trainee resulting in continuation and perpetuation of the same professional attitudes and behaviours. Evidence appeared to have limited influence on OTC decision making. The tutor played a key role in the trainee's professional development. More work could be performed to investigate how evidence can be regarded as relevant and something that is consistently implemented in practice. © 2014 John Wiley & Sons, Ltd.

I. INTRODUCTION: UNDERSTANDING MEDICINES AND MEDICAL INTERVENTIONS.

Science.gov (United States)

Lockhart, Kristi L; Keil, Frank C

2018-06-01

We live in an increasingly pharmacological and medical world, where children and adults frequently encounter alleged treatments for an enormous range of illnesses. How do we come to understand what heals and why? Here, 15 studies explore how 1,414 children (ages 5-11) and 882 adults construe the efficacies of different kinds of cures. Developmental patterns in folk physics, psychology, and biology lead to predictions about which expectations about cures will remain relatively constant across development and which will change. With respect to stability, we find that even young school children (ages 5-7) distinguish between physical and psychological disorders and the treatments most effective for each. In contrast, young children reason differently about temporal properties associated with cures. They often judge that dramatic departures from prescribed schedules will continue to be effective. Young children are also less likely than older ages to differentiate between the treatment needs of acute versus chronic disorders. Young children see medicines as agent-like entities that migrate only to afflicted regions while having "cure-all" properties, views that help explain their difficulties grasping side effects. They also differ from older children and adults by judging pain and effort as reducing, instead of enhancing, a treatment's power. Finally, across all studies, optimism about treatment efficacy declines with age. Taken together, these studies show major developmental changes in how children envision the ways medicines work in the body. Moreover, these findings link to broader patterns in cognitive development and have implications for how medicines should be explained to children. © 2018 The Society for Research in Child Development, Inc.

To describe the nationwide impact of a restrictive law on over-the-counter sales of antimicrobial drugs, implemented in Brazil in November 2010. Approximately 75% of the population receives healthcare from the public health system and receives free-of-charge medication if prescribed. Total sales in private pharmacies as compared with other channels of sales of oral antibiotics were evaluated in this observational study before and after the law (2008-2012). Defined daily dose per 1000 inhabitants per day (DDD/TID) was used as standard unit. In private pharmacies the effect of the restrictive law was statistically significant (P sales was observed (P = 0.643). The impact in the South and Southeast (more developed) regions was higher than in the North, Northeast, and Mid-West. The state capitals had a 19% decrease, compared with 0.8% increase in the rest of the states. Before the law, the sales of antimicrobial drugs were steadily increasing. From November 2010, with the restrictive law, there was an abrupt drop in sales followed by an increase albeit at a significantly lower rate. The impact was higher in regions with better socio-economic status.

Adverse drug reactions and drug–drug interactions with over-the-counter NSAIDs

Full Text Available Nicholas Moore,1 Charles Pollack,2 Paul Butkerait2 1Department of Pharmacology, Université de Bordeaux, Bordeaux, France; 2Pfizer Consumer Healthcare, Madison, NJ, USA Abstract: Nonsteroidal anti-inflammatory drugs (NSAIDs such as ibuprofen have a long history of safe and effective use as both prescription and over-the-counter (OTC analgesics/antipyretics. The mechanism of action of all NSAIDs is through reversible inhibition of cyclooxygenase enzymes. Adverse drug reactions (ADRs including gastrointestinal bleeding as well as cardiovascular and renal effects have been reported with NSAID use. In many cases, ADRs may occur because of drug–drug interactions (DDIs between the NSAID and a concomitant medication. For example, DDIs have been reported when NSAIDs are coadministered with aspirin, alcohol, some antihypertensives, antidepressants, and other commonly used medications. Because of the pharmacologic nature of these interactions, there is a continuum of risk in that the potential for an ADR is dependent on total drug exposure. Therefore, consideration of dose and duration of NSAID use, as well as the type or class of comedication administered, is important when assessing potential risk for ADRs. Safety findings from clinical studies evaluating prescription-strength NSAIDs may not be directly applicable to OTC dosing. Health care providers can be instrumental in educating patients that using OTC NSAIDs at the lowest effective dose for the shortest required duration is vital to balancing efficacy and safety. This review discusses some of the most clinically relevant DDIs reported with NSAIDs based on major sites of ADRs and classes of medication, with a focus on OTC ibuprofen, for which the most data are available.

1979-01-01

A methane filled proton-recoil proportional counter will be used as a fission neutron detector in the fast-neutron hodoscope. To provide meaningful fuel-motion information the proportional counter should have: a linear response over a wide range of reactor powers background ratio (the number of high energy neutrons detected must be maximized relative to low energy neutrons, and gamma ray sensitivity must be kept small); and a detector efficiency for fission neutrons above 1 MeV of approximately 1%. In addition, it is desirable that the detector and the associated amplifier/discriminator be capable of operating at counting rates in excess of 500 kHz. This paper reports on tests that were conducted on several proportional counters at the TREAT reactor

2017-01-01

National conference didactic lectures have traditionally featured hour-long lecture-based presentations. However, there is evidence that longer lectures can lead to both decreased attention and retention of information. The authors sought to identify trends in lecture duration, lecture types, and number of speakers at four national emergency medicine (EM) conferences over a 6-year period. The authors performed a retrospective analysis of the length, number of speakers, and format of didactic lectures at four different national EM conferences over 6 years. The authors abstracted data from the national academic assemblies for the four largest not-for-profit EM organizations in the United States: American Academy of Emergency Medicine, American College of Emergency Physicians, Council of Emergency Medicine Residency Directors, and Society for Academic Emergency Medicine. There was a significant yearly decrease in the mean lecture lengths for three of the four conferences. There was an increase in the percentage of rapid fire sessions over the preceding 2 years with a corresponding decrease in the percentage of general educational sessions. There was no significant difference in the mean number of speakers per lecture. An analysis of 4210 didactic lecture sessions from the annual meetings of four national EM organizations over a 6-year period showed significant decreases in mean lecture length. These findings can help to guide EM continuing medical education conference planning and research.

A wide array of wildlife species, including many animals, are used in traditional medicines across many medicinal systems, including in Traditional Chinese Medicine (TCM). Due to over-exploitation and habitat loss, the populations of many animals commonly used in TCM have declined and are unable to meet market demand. A number of measures have been taken to try to reduce the impact that this large and growing market for TCM may have on wild animal species. Consumer preferences and behavior are known to play an important role in the consumption and protection of wild animals used in traditional medicine, and thus are likely to be an important factor in the success of many of these mechanisms—particularly given the significant percentage of TCMs that are over-the-counter products (access to which is not mediated by practitioners). In this study we conducted questionnaires and designed stated preference experiments embodying different simulation scenarios using a random sample of the population in Beijing to elicit individuals’ knowledge, perceptions and preferences toward wild or farmed animal materials and their substitutes used in traditional Chinese medicine. We found that respondents had a stated preference for wild materials over farm-raised and other alternatives because they believe that the effectiveness of wild-sourced materials is more credible than that of other sources. However, we also found that, although respondents used TCM products, they had a poor understanding of the function or composition of either traditional Chinese medicines or proprietary Chinese medicines (PCM), and paid little attention to the composition of products when making purchasing decisions. Furthermore, awareness of the need for species protection, or “conservation consciousness” was found to play an important role in willingness to accept substitutions for wild animal materials, while traditional animal medicinal materials (TAMs) derived from well-known endangered species

Retail sales of over the counter (OTC) medications have risen steadily over the years; however, these products are not without potential risk. The aim of this study was to describe the marketing strategies used to promote OTC medicines to children and their parents. Data were collected from 187 product packaging of fever reducer, allergy, and cough medicines posted on the Internet sites of three of the largest pharmacies in the United States. Specific marketing information was collected related to flavorings and pictures appearing on the packaging. There was no significant difference between the type of medicine and whether they were flavored or not, as almost every product (95.7 %) indicated that it resembles a food flavoring. On almost all the packaging (92.5 %) the flavor was also indicated by words in different font sizes. Most of the products (83.4 %) showed a picture of a food product on their packaging. There was a significant difference between the medicine types by picture, with fever medicines having more pictures of food than either cough or allergy medicine. Stronger regulations of marketing strategies of these products are needed.

Multimode pulse counter

International Nuclear Information System (INIS)

Natanzon, D.D.

1982-01-01

A pulse counter with code conversion is described. The counter is based on the integrated circuits of direct-counting devices of medium integration. The counter ensures various modes of pulse counting depending on the logical control signals: reversible, two-channel summing, one-channel summing binary, summing with ''storage'' signal code fixation without interrupting pulse counting. Arrangement of the suggested structure as a microcircuit of medium integration might contribute to reduction in the counter type nomenclature in digital families of widely used integrated circuits

Stumpfe, Dagmar; Hu, Ye; Dimova, Dilyana; Bajorath, Jürgen

2014-01-09

The activity cliff concept is of high relevance for medicinal chemistry. Recent studies are discussed that have further refined our understanding of activity cliffs and suggested different ways of exploiting activity cliff information. These include alternative approaches to define and classify activity cliffs in two and three dimensions, data mining investigations to systematically detect all possible activity cliffs, the introduction of computational methods to predict activity cliffs, and studies designed to explore activity cliff progression in medicinal chemistry. The discussion of these studies is complemented with new findings revealing the frequency of activity cliff formation when different molecular representations are used and the distribution of activity cliffs across different targets. Taken together, the results have a number of implications for the practice of medicinal chemistry.

To investigate the efficacy and safety of CS1002, an over-the-counter cough treatment containing diphenhydramine, ammonium chloride and levomenthol in a cocoa-based demulcent. A multicentre, randomised, parallel group, controlled, single-blinded study in participants with acute upper respiratory tract infection-associated cough. 4 general practitioner (GP) surgeries and 14 pharmacies in the UK. Participants aged ≥18 years who self-referred to a GP or pharmacist with acute cough of <7 days' duration. Participant inclusion criterion was cough severity ≥60 mm on a 0-100 mm visual analogue scale (VAS). Exclusion criteria included current smokers or history of smoking within the past 12 months (including e-cigarettes). 163 participants were randomised to the study (mean participant age 38 years, 57% females). Participants were randomised to CS1002 (Unicough) or simple linctus (SL), a widely used cough treatment, and treatment duration was 7 days or until resolution of cough. The primary analysis was intention-to-treat (157 participants) and comprised cough severity assessed using a VAS after 3 days' treatment (prespecified primary end point at day 4). Cough frequency, sleep disruption, health status (Leicester Cough Questionnaire (LCQ-acute)) and cough resolution were also assessed. At day 4 (primary end point), the adjusted mean difference (95% CI) in cough severity VAS between CS1002 and SL was -5.9 mm (-14.4 to 2.7), p=0.18. At the end of the study (day 7) the mean difference in cough severity VAS was -4.2 mm (-12.2 to 3.9), p=0.31. CS1002 was associated with a greater reduction in cough sleep disruption (mean difference -11.6 mm (-20.6 to 2.7), p=0.01) and cough frequency (mean difference -8.1 mm (-16.2 to 0.1), p=0.05) compared with SL. There was greater improvement in LCQ-acute quality of life scores with CS1002 compared with SL: mean difference (95% CI) 1.2 (0.05 to 2.36), p=0.04 after 5 days' treatment.

The particle identification system of the KEDR detector is based on aerogel threshold Cherenkov counters called ASHIPH counters. The system consists of 160 counters arranged in two layers. An event reconstruction program for the ASHIPH system was developed. The position of each counter relative to the tracking system was determined using cosmic muons and Bhabha events. The geometric efficiency of the ASHIPH system was verified with Bhabha events. The efficiency of relativistic particle detection was measured with cosmic muons. A π/K separation of 4δ in the momentum range 0.95 −1.45 GeV/c was confirmed. A simulation program for the ASHIPH counters has been developed.

The role of the Therapeutic Goods Administration and the Medicine and Medical Devices Safety Authority in evaluating complementary and alternative medicines in Australia and New Zealand

Ghosh, Dilip; Skinner, Margot; Ferguson, Lynnette R.

2006-01-01

Currently, the regulation of complementary and alternative medicines and related health claims in Australia and New Zealand is managed in a number of ways. Complementary medicines, including herbal, minerals, nutritional/dietary supplements, aromatherapy oils and homeopathic medicines are regulated under therapeutic goods/products legislation. The Therapeutic Goods Administration (TGA), a division of the Commonwealth Department of Health and Ageing is responsible for administering the provisions of the legislation in Australia. The New Zealand Medicines and Medical Devices Safety Authority (Medsafe) administers the provision of legislation in New Zealand. In December 2003 the Australian and New Zealand governments signed a Treaty to establish a single, bi-national agency to regulate therapeutic products, including medical devices prescription, over-the-counter and complementary medicines. A single agency will replace the Australian TGA and the New Zealand Medsafe. The role of the new agency will be to safeguard public health through regulation of the quality, safety and efficacy or performance of therapeutic products in both Australia and New Zealand. The major activities of the new joint Australia New Zealand therapeutic products agency are in product licensing, specifying labelling standards and setting the advertising scheme, together with determining the risk classes of medicines and creating an expanded list of ingredients permitted in Class I medicines. A new, expanded definition of complementary medicines is proposed and this definition is currently under consultation. Related Australian and New Zealand legislation is being developed to implement the joint scheme. Once this legislation is passed, the Treaty will come into force and the new joint regulatory scheme will begin. The agency is expected to commence operation no later than 1 July 2006 and will result in a single agency to regulate complementary and alternative medicines

Analyzing readability of medicines information material in Slovenia

Kasesnik, Karin; Kline, Mihael

2011-01-01

Objective: Readability has been claimed to be an important factor for understanding texts describing health symptoms and medications. Such texts may be a factor which indirectly affects the health of the population. Despite the expertise of physicians, the readability of information sources may be important for acquiring essential treatment information. The aim of this study was to measure the readability level of medicines promotion material in Slovenia. Methods: The Flesch readability formula was modified to comply with Slovene texts. On the basis of determining the Slovene readability algorithm, the readability ease related to the readability grade level of different Slovene texts was established. In order to estimate an adjustment of the texts to the recommended readability grade level of the targeted population, readability values of English texts were set. One sample t-test and standard deviations from the arithmetic mean values were used as statistical tests. Results: The results of the research showed low readability scores of the Slovene texts. Difficult readability values were seen in different types of examined texts: in patient information leaflets, in the summaries of product characteristics, in promotional materials, while describing over-the-counter medications and in the materials for creating disease awareness. Especially low readability values were found within the texts belonging to promotional materials intended for the physicians. None of researched items, not even for the general public, were close to primary school grade readability levels and therefore could not be described as easily readable. Conclusion: This study provides an understanding of the level of readability of selected Slovene medicines information material. It was concluded that health-related texts were not compliant with general public or with healthcare professional needs. PMID:23093886

Technical Note: Characterization of a static thermal-gradient CCN counter

2007-06-01

Full Text Available The static (parallel-plate thermal-gradient diffusion chamber (SDC was one of the first instruments designed to measure cloud condensation nuclei (CCN concentrations as a function of supersaturation. It has probably also been the most widely used type of CCN counter. This paper describes the detailed experimental characterization of a SDC CCN counter, including calibration with respect to supersaturation and particle number concentration. In addition, we investigated the proposed effect of lowered supersaturation because of water vapor depletion with increasing particle concentration. The results obtained give a better understanding why and in which way it is necessary to calibrate the SDC CCN counter. The calibration method is described in detail and can, in parts, be used for calibrations also for other types of CCN counters.

We conclude the following: 1 it is important to experimentally calibrate SDC CCN counters with respect to supersaturation, and not only base the supersaturation on the theoretical description of the instrument; 2 the number concentration calibration needs to be performed as a function of supersaturation, also for SDC CCN counter using the photographic technique; and 3 we observed no evidence that water vapor depletion lowered the supersaturation.

The counter ion: expanding excipient functionality

Full Text Available Excipients have increasingly become 'enablers' of drug delivery and efficacy rather than passive bystanders. Advances in pharmaceutical technology have enabled the ability to deliver specific counter ions (in the form of the counter ion containing excipient and the API simultaneously to preselected targets in the body. This, coupled with a near universal mechanism of columbic interactions that determine the [API- counter ion] efficacy, can be harnessed to exploit this hitherto unavailable or unrecognized enabling mechanism. New excipients may be assembled by a near inexhaustible supply of different permutations of counter ions and their judicious use in specific situations could potentially drive a renaissance in excipient innovation (and drug delivery and efficacy despite regulatory stagnation.

Full Text Available Governments produce both deliberate and involuntary (and less conscious narratives when countering terrorism. The thesis of this article is that such unintended messages can be much more powerful and consequential than is realized; in fact, they can completely contradict the intended official 'counter-narrative'. To substantiate this hypothesis, the author looks at the experience of the German Federal Republic in the 1970s and beyond when state and society were confronted with the Red Army Faction (RAF and similar left-wing "revolutionaries" like those of the 2nd of June Movement or the Red Zora.

The use of a custom-made cylindrical graphite proportional counter (Cy-GPC) along with a cylindrical tissue equivalent proportional counter (TEPC) for neutron-gamma mixed-field dosimetry has been studied in the following steps: first, the consistency of the gamma dose measurement between the Cy-TEPC and the Cy-GPC was investigated over a range of 20 keV (X-ray) to 0.661 MeV (Cs-137 gamma ray). Then, with both the counters used simultaneously, the neutron and gamma ray doses produced by a P385 Neutron Generator (Thermo Fisher Scientific) together with a Cs-137 gamma source were determined. © The Author(s) 2018.

The Micro Trench Gas Counter

International Nuclear Information System (INIS)

Schmitz, J.

1991-07-01

A novel design is presented for a gas avalanche chamber with micro-strip gas readout. While existing gaseous microstrip detectors (Micro-strip Gas Counters, Knife edge chambers) have a minimum anode pitch of the order of 100 μm, the pitch of the discussed Micro Trench Gas Counter goes down to 30-50 μm. This leads to a better position resolution and two track separation, and a higher radiation resistivity. Its efficiency and signal speed are expected to be the same as the Microstrip Gas Counter. The energy resolution of the device is expected to be equal to or better than 10 percent for the 55 Fe peak. Since the anode strip dimensions are larger than those in a MSGC, the device may be not as sensitive to discharges and mechanical damage. In this report production of the device is briefly described, and predictions on its operation are made based on electric field calculations and experience with the Microstrip Gas Counter. The authors restrict themselves to the application in High Energy Physics. (author). 10 refs.; 9 figs

A Fear Management Approach to Counter-Terrorism

Tinka Veldhuis

2012-02-01

Full Text Available Spreading fear is the essence of terrorism. Terrorists exploit fear by terrorising the target audience into concessions. Understanding how feelings of fear influence the way people feel, think and act is therefore an important starting point to explore how individuals and societies can learn how to cope with fear of terrorism. In this Policy Brief, Research Fellows Prof. Dr. Edwin Bakker and Dr. Tinka Veldhuis explore the dynamics of fear in response to terrorism, and emphasise the importance of integrating initiatives to manage fear of terrorism and reduce its negative consequences into overarching counter-terrorism strategies. It argues that societies can benefit greatly from promoting resilience and a fear management approach to counter-terrorism.

2014-01-01

Today, herb medicines have become the major source for discovery of novel agents in countermining diseases. However, many of them are largely under-explored in pharmacology due to the limitation of current experimental approaches. Therefore, we proposed a computational framework in this study for network understanding of herb pharmacology via rapid identification of putative ingredient-target interactions in human structural proteome level. A marketing anti-cancer herb medicine in China, Yadanzi (Brucea javanica), was chosen for mechanistic study. Total 7,119 ingredient-target interactions were identified for thirteen Yadanzi active ingredients. Among them, about 29.5% were estimated to have better binding affinity than their corresponding marketing drug-target interactions. Further Bioinformatics analyses suggest that simultaneous manipulation of multiple proteins in the MAPK signaling pathway and the phosphorylation process of anti-apoptosis may largely answer for Yadanzi against non-small cell lung cancers. In summary, our strategy provides an efficient however economic solution for systematic understanding of herbs' power.

Nuclear Medicine in Turkey

2001-01-01

Nuclear Medicine is a medical specialty that uses radionuclides for the diagnosis and treatment of diseases and it is one of the most important peaceful applications of nuclear sciences. Nuclear Medicine has a short history both in Turkey and in the world. The first use of I-131 for the treatment of thyrotoxicosis in Turkey was in 1958 at the Istanbul University Cerrahpasa Medical School. In 1962, Radiobiological Institute in Ankara University Medical School was established equipped with well-type counters, radiometers, scalers, external counters and a rectilinear scanner. In 1965, multi-probe external detection systems, color dot scanners and in 1967, anger scintillation camera had arrived. In 1962, wet lab procedures and organ scanning, in 1965 color dot scanning, dynamic studies (blood flow - renograms) and in 1967 analogue scintillation camera and dynamic camera studies have started. In 1974, nuclear medicine was established as independent medical specialty. Nuclear medicine departments have started to get established in 1978. In 1974, The Turkish Society of Nuclear Medicine (TSNM) was established with 10 members. The first president of TSNM was Prof. Dr. Yavuz Renda. Now, in the year 2000, TSNM has 349 members. Turkish Society of Nuclear Medicine is a member of European Association of Nuclear Medicine (EANM), World Federation of Nuclear Medicine and Biology (WFNMB) and WFNMB Asia-Oceania. Since 1974, TSNM has organized 13 national Nuclear Medicine congresses, 4 international Nuclear Oncology congresses and 13 nuclear medicine symposiums. In 1-5 October 2000, 'The VII th Asia and Oceania Congress of Nuclear Medicine and Biology' was held in Istanbul, Turkey. Since 1992, Turkish Journal of Nuclear Medicine is published quarterly and it is the official publication of TSNM. There are a total of 112 Nuclear Medicine centers in Turkey. There are 146 gamma cameras. (52 Siemens, 35 GE, 16 Elscint, 14 Toshiba, 10 Sopha, 12 MIE, 8 Philips, 9 Others) Two cyclotrons are

Townsend coefficients of gases in avalanche counters

International Nuclear Information System (INIS)

Brunner, G.

1978-01-01

Though much work has been done by many authors in the last few years in the development and application of avalanche counters for ion radiation, it is based upon values of the Townsend coefficients as the essential gas parameter, which were determined many years ago for much lower reduced field strengths F/p than prevail in such counters. Therefore absolute determinations of α in vapours of methyl alcohol, cyclohexane, acetone, and n-heptene were performed under original conditions of avalanche counters. The values obtained do not differ by more than 30%-50% from the former values indeed, extrapolated over F/p for the first three mentioned substances, but the amounts of A and B in the usual representation α/p=A exp(-B(F/p)) are much greater for the stronger reduced fields. This is of importance for such counter properties as the dependence of pulse heights on pressure, voltage, electrode distance etc., which are governed by other combinations of A and B than α/p itself. A comparison of results for different ionic radiations shows a marked influence of the primary ionization density along the particle tracks which is hard to explain. (Auth.)

2002-01-01

Muon detection is fundamental to many of the interesting analyses at CDF II. For more efficient muon registration in Run II it was decided to increase geometrical coverage. The so-called 'miniskirt' counters are part of this upgrade. The original design parameters of the 'miniskirt' and mixed 'miniskirt' scintillation counters for the CDF Muon System are presented. The modifications, testing and installation of these counters within the CDF Upgrade Project are described in detail. The timing characteristics of mixed 'miniskirt' counters are also investigated using cosmic muons. The measurements show that the time resolution does not exceed 2.2 ns

The Noisy Counter-Revolution: Understanding the Cultural Conditions and Dynamics of Populist Politics in Europe in the Digital Age

Directory of Open Access Journals (Sweden)

Lars Rensmann

2017-12-01

Full Text Available The article argues for a cultural turn in the study of populist politics in Europe. Integrating insights from three fields—political sociology, political psychology, and media studies—a new, multi-disciplinary framework is proposed to theorize particular cultural conditions favorable to the electoral success of populist parties. Through this lens, the fourth wave of populism should be viewed as a “noisy”, anti-cosmopolitan counter-revolution in defense of traditional cultural identity. Reflective of a deep-seated, value-based great divide in European democracies that largely trumps economic cleavages, populist parties first and foremost politically mobilize long lingering cultural discontent and successfully express a backlash against cultural change. While the populist counter-revolution is engendered by profoundly transformed communicative conditions in the age of social media, its emotional force can best be theorized with the political psychology of authoritarianism: as a new type of authoritarian cultural revolt.

Traditional Chinese Medicine (TCM) serves as the most common alternative therapeutic approach for Western medicine and benefits IBS patients globally. Due to the lack of scientific evidence in the past, TCM formulas were not internationally well recognized as promising IBS remedies. In this review, firstly, we present the etiology and therapy of IBS in terms of traditional Chinese medical theory. Secondly, we summarize the clinical randomized controlled trials (RCTs) of TCM formulas for IBS patients that are available in the literature (from 1998 to September 2013), in which 14 RCTs conducted of high quality were discussed in detail. Of the 14 selected trials, 12 of those concluded that TCM formulas provided superior improvement in the global symptoms of IBS patients over the placebo or conventional medicines. As well, all 14 RCTs suggested that TCM formulas have good safety and tolerability. Last but not least, we explore the pharmacological mechanisms of the anti-IBS TCM formulas available in the literature (from 1994 to September, 2013). Collectively, in combating IBS symptoms, most TCM formulas exert multi-targeting actions including the regulation of neurotransmitters and hormones in the enteric nervous system (ENS), modulation of smooth muscle motility in the gastrointestinal (GI) tract, modulation of the hypothalamic-pituitary-adrenal (HPA) axis, attenuation of intestinal inflammation and restoration of intestinal flora, etc. In conclusion, TCM formulas appear to be promising for IBS treatment. This review provides a useful reference for the public in furthering a better understanding and acceptance of TCM formulas as IBS remedies.

Many patients with human immunodeficiency virus infection use traditional, complementary, and alternative medicines and other practices to combat the disease, with some also using prescribed antiretroviral therapy provided by the public health sector. This study aimed to establish the awareness of public sector biomedical health care providers on the use of traditional, complementary and alternative medicines by HIV-infected patients who also used highly active antiretroviral therapy, and to determine whether this was based on patients seen or cases being reported to them. Potential risks of interactions between the prescribed antiretroviral and non-prescribed medication therapies may pose safety and effectiveness issues in patients using both types of treatment. A descriptive cross-sectional study, using a researcher administered semi-structured questionnaire, was conducted from June to August 2013 at ten public sector antiretroviral clinics in five regional, three specialised and two district hospitals in eThekwini Health District, South Africa. Questionnaires were administered through face-to face interview to 120 eligible participants consisting of doctors, nurses, pharmacists and post-basic pharmacist assistants in HIV clinical practice. The results are presented as percent or proportion with standard error (SE), or as frequency. Ninety-four respondents completed the questionnaire, yielding a response rate of 78.3 %. Almost half (48/94) were aware of patients using African traditional herbal medicines, over-the-counter supplements, unnamed complementary Ayurveda medicines and acupuncture. Twenty-three of the 94 respondents (24.4 %) said they had consulted patients who were using both antiretroviral therapy and certain types of non-prescribed medication in the previous three months. Awareness among healthcare providers on patient use of traditional, complementary and alternative medicines was relatively high. Few respondents had seen patients who used mostly

Menstrual cups have been available for decades, but their use is limited by bulky design and the need for multiple sizes. The Softcup® (Instead, Inc., San Diego, CA) is a simple single-size disposable over-the-counter (OTC) menstrual cup that compresses to tampon shape to facilitate insertion and can be worn during coitus. This report describes preclinical evaluation, clinical testing, and postmarketing monitoring of the Softcup. Preclinical testing complied with U.S. Food and Drug Administration (FDA) guidelines and used standard United States Pharmacopoeia methodologies for assessment of potential toxicity. Clinical testing enrolled 406 women in seven U.S. centers. A detailed written questionnaire assessed safety, acceptability, and effectiveness for menstrual collection. Study safety parameters included pelvic examinations, Pap smears, colposcopy, urinalysis, vaginal pH, wet mounts, gram stain, and vaginal microflora cultures. Postmarketing surveillance of over 100 million Softcups has been conducted by the manufacturer and by the FDA Medwatch system. No toxicity or mutagenicity was observed in preclinical evaluations. In clinical testing, after three cycles of cup use, 37% of subjects rated the cup as better than, 29% as worse than, and 34% as equal to pads or tampons. The cup was preferred for comfort, dryness, and less odor. Cups received lower ratings for disposal and convenience. Eighty-one percent of enrolled women were able to insert and remove their first cup using only written instructions. Use difficulties resulting in study discontinuations included cramping (1%), leakage (1%), and improper fit (3%). No safety parameters were adversely affected. No significant health risks were reported during postmarketing surveillance. These results demonstrate that a single-size vaginal device has no significant health risks and is acceptable to many women without the need for fitting or other medical services.

The paper describes a gas plant and gaseous scintillation counter, and gives the results of experiments on the recording and spectrometry of neutron beams using a gaseous scintillation counter filled with a mixture of 10% xenene and 90% helium-3 at an overall pressure of 20 ata. Data are given on the design of the gas plant, which makes it possible to operate the counter continuously over long periods of time, as well as providing the required gas mixtures at overall pressures of up to 60 atm and ensuring constant freedom of the gas from contamination. In addition, the paper presents the results of research on the counter's energy resolution and linearity at different energy levels and indicates its efficiency in gamma fields of intensity up to 3 r/h; the possibility of extending the working energy-range of gaseous scintillation counters filled with helium-3 is also considered.

Constant sensitivity circuit for solid state nuclear radiation counters

International Nuclear Information System (INIS)

Kronenberg, S.; Erkkila, B.

1985-01-01

The utilization of solid state counters in tactical radiological instruments for measuring intensities and doses of fallout gamma rays offers advantages over Geiger-Mueller (GM) counters such as a much wider dynamic range and low operating voltages. Their very small size is suitable for use in miniaturized equipment. However, these devices have a serious problem if used in a mixed, fast neutron/gamma environment such as is encountered e.g. in a battlefield where tactical nuclear weapons are used and neutrons, prompt, initial gammas and fallout gammas are killing factors of comparable importance. Exposure to fast neutrons reduces seriously their sensitivity. This makes the solid state counters at this time unacceptable for use in Army tactical surveillance equipment and in other applications where according to requirements the performance must not be impaired by exposure to fast neutrons. It seems to be possible to reduce to some extent this neutron generated damage by improving the crystal counters

To assess whether dietary supplements that are herbal and/or animal-derived products, marketed for enhancing metabolism or promoting energy, "adrenal fatigue," or "adrenal support," contain thyroid or steroid hormones. Twelve dietary adrenal support supplements were purchased. Pregnenolone, androstenedione, 17-hydroxyprogesterone, cortisol, cortisone, dehydroepiandrosterone sulfate, synthetic glucocorticoids (betamethasone, dexamethasone, fludrocortisone, megestrol acetate, methylprednisolone, prednisolone, prednisone, budesonide, and triamcinolone acetonide) levels were measured twice in samples in a blinded fashion. This study was conducted between February 1, 2016, and November 1, 2016. Among steroids, pregnenolone was the most common hormone in the samples. Budesonide, 17-hydroxyprogesterone, androstenedione, cortisol, and cortisone were the others in order of prevalence. All the supplements revealed a detectable amount of triiodothyronine (T3) (63-394.9 ng/tablet), 42% contained pregnenolone (66.12-205.2 ng/tablet), 25% contained budesonide (119.5-610 ng/tablet), 17% contained androstenedione (1.27-7.25 ng/tablet), 8% contained 17-OH progesterone (30.09 ng/tablet), 8% contained cortisone (79.66 ng/tablet), and 8% contained cortisol (138.5 ng/tablet). Per label recommended doses daily exposure was up to 1322 ng for T3, 1231.2 ng for pregnenolone, 1276.4 ng for budesonide, 29 ng for androstenedione, 60.18 ng for 17-OH progesterone, 277 ng for cortisol, and 159.32 ng for cortisone. All the supplements studied contained a small amount of thyroid hormone and most contained at least 1 steroid hormone. This is the first study that measured thyroid and steroid hormones in over-the-counter dietary "adrenal support" supplements in the United States. These results may highlight potential risks of hidden ingredients in unregulated supplements. Copyright © 2017 Mayo Foundation for Medical Education and Research. Published by Elsevier Inc.

The scintillation-counters system of the SAPHIR-detector at the stretcher accelerator ELSA in Bonn consists of 64 counters. It supplies a fast hadronic trigger and is utilizised for the particle identification by time of flight measurements. Prototypes of the counters (340x21.25 x 6.0 cm 3 ) had been tested. The contribution to the resolution of the time of flight measurement was measured to σ=125 ps, the effective light velocity to 17.5 ns/cm and the attenuation length of 7.8 m. A pion kaon separation is possible up to a momentum of 1 GeV/c with time of flight measurement. With the first photon-beam at SAPHIR the counters were tested, first triggers were obtained and evaluated. (orig.) [de

[Ethics and medicine in Michel Foucault: the humanistic dimension of medicine derived from a genealogy of morality].

Science.gov (United States)

Gomes, Benjamim

2005-01-01

The article presents the results of a doctoral dissertation defended at the Universidad de Salamanca, based on Foucault's final decade of writings. If Foucault's goal in writing The History of Sexuality was to fashion a genealogy of ethics, my goal in analyzing this book, along with his other writings, is to demonstrate his last contribution to the history of medicine. He moves from a conception of power over others towards a conception of power over oneself, an exclusive terrain of ancient Greek morality. As a thinker who tries to understand today's problems by going to their roots, Foucault develops less a history than a philosophy of history. Considered an anti-humanist, he leaves us with a portrait of a wholly ethical-humanistic medicine.

Formulations of over the counter (OTC) NSAIDs differ substantially, but information is lacking on whether this alters their gastrointestinal profiles. To assess disintegration and dissolution rates and pharmacokinetics of four preparations of OTC ibuprofen and relate these with spontaneously reported gastrointestinal adverse events. Disintegration and dissolution rates of ibuprofen tablets as (a) acid, (b) sodium salt, (c) lysine salt, and (d) as a liquid gelatine capsule were assessed. Pharmacokinetic data gastrointestinal and spontaneously reported adverse events arising from global sales were obtained from files from Reckitt Benckiser. Disintegration at low pH was progressively shorter for the preparations from a-to-d with formation of correspondingly smaller ibuprofen crystals, while dissolution was consistently poor. Dissolution at a neutral pH was least rapid for the liquid gelatine capsule. Pharmacokinetic data showed a shorter t max and a higher C max for preparations b-d as compared with ibuprofen acid. Spontaneously reported abdominal symptoms were rare with the liquid gelatine preparation. The formulations of OTC ibuprofen differ in their disintegration and dissolution properties, pharmacokinetic profiles and apparent gastrointestinal tolerability. Spontaneously reported abdominal symptoms were five times lower with the liquid gelatine capsule as compared with ibuprofen acid despite a 30% increase in C max . © 2017 Royal Pharmaceutical Society.

Understanding wind turbine price trends in the U.S. over the past decade

International Nuclear Information System (INIS)

Bolinger, Mark; Wiser, Ryan

2012-01-01

On a $/kW basis, wind turbine prices in the U.S. have declined by nearly one-third on average since 2008, after having previously doubled over the period from 2002 through 2008. These two substantial and opposing trends over the past decade – and particularly the earlier price doubling – run counter to the smooth, gradually declining cost trajectories predicted by standard learning curve theory. Taking a bottom-up approach, we examine seven possible drivers of wind turbine prices in the U.S., with the goal of estimating the degree to which each contributed to the doubling in turbine prices from 2002 through 2008, as well as the subsequent decline in prices through 2010. In aggregate, these seven drivers – which include changes in labor costs, warranty provisions, manufacturer profitability, turbine scaling, raw materials prices, energy prices, and foreign exchange rates – explain from 70% to 90% (depending on the year) of empirically observed wind turbine price movements in the U.S. through 2010. Turbine scaling is found to have been the largest single contributor to the price doubling through 2008, although the incremental cost of scaling has been justified by greater energy capture, resulting in a lower cost of wind generation. - Highlights: ► Having doubled from 2002 to 2008, wind turbine prices have since fallen by one-third. ► We analyze seven potential drivers of wind turbine prices over the past decade. ► Turbine scaling has had the largest influence, followed by weakness in the dollar. ► Changes in the price of energy inputs had the smallest impact.

Understanding Liver Regeneration: From Mechanisms to Regenerative Medicine.

Gilgenkrantz, Hélène; Collin de l'Hortet, Alexandra

2018-04-16

Liver regeneration is a complex and unique process. When two-thirds of a mouse liver is removed, the remaining liver recovers its initial weight in approximately 10 days. The understanding of the mechanisms responsible for liver regeneration may help patients needing large liver resections or transplantation and may be applied to the field of regenerative medicine. All differentiated hepatocytes are capable of self-renewal, but different subpopulations of hepatocytes seem to have distinct proliferative abilities. In the setting of chronic liver diseases, a ductular reaction ensues in which liver progenitor cells (LPCs) proliferate in the periportal region. Although these LPCs have the capacity to differentiate into hepatocytes and biliary cells in vitro, their ability to participate in liver regeneration is far from clear. Their expansion has even been associated with increased fibrosis and poorer prognosis in chronic liver diseases. Controversies also remain on their origin: lineage studies in experimental mouse models of chronic injury have recently suggested that these LPCs originate from hepatocyte dedifferentiation, whereas in other situations, they seem to come from cholangiocytes. This review summarizes data published in the past 5 years in the liver regeneration field, discusses the mechanisms leading to regeneration disruption in chronic liver disorders, and addresses the potential use of novel approaches for regenerative medicine.

Robotic Billiards: Understanding Humans in Order to Counter Them.

Nierhoff, Thomas; Leibrandt, Konrad; Lorenz, Tamara; Hirche, Sandra

2016-08-01

Ongoing technological advances in the areas of computation, sensing, and mechatronics enable robotic-based systems to interact with humans in the real world. To succeed against a human in a competitive scenario, a robot must anticipate the human behavior and include it in its own planning framework. Then it can predict the next human move and counter it accordingly, thus not only achieving overall better performance but also systematically exploiting the opponent's weak spots. Pool is used as a representative scenario to derive a model-based planning and control framework where not only the physics of the environment but also a model of the opponent is considered. By representing the game of pool as a Markov decision process and incorporating a model of the human decision-making based on studies, an optimized policy is derived. This enables the robot to include the opponent's typical game style into its tactical considerations when planning a stroke. The results are validated in simulations and real-life experiments with an anthropomorphic robot playing pool against a human.

Maternal bodies and medicines: a commentary on risk and decision-making of pregnant and breastfeeding women and health professionals

Directory of Open Access Journals (Sweden)

McDonald Karalyn

2011-11-01

Full Text Available Abstract Background The perceived risk/benefit balance of prescribed and over-the-counter (OTC medicine, as well as complementary therapies, will significantly impact on an individual’s decision-making to use medicine. For women who are pregnant or breastfeeding, this weighing of risks and benefits becomes immensely more complex because they are considering the effect on two bodies rather than one. Indeed the balance may lie in opposite directions for the mother and baby/fetus. The aim of this paper is to generate a discussion that focuses on the complexity around risk, responsibility and decision-making of medicine use by pregnant and breastfeeding women. We will also consider the competing discourses that pregnant and breastfeeding women encounter when making decisions about medicine. Discussion Women rely not only on biomedical information and the expert knowledge of their health care professionals but on their own experiences and cultural understandings as well. When making decisions about medicines, pregnant and breastfeeding women are influenced by their families, partners and their cultural societal norms and expectations. Pregnant and breastfeeding women are influenced by a number of competing discourses. “Good” mothers should manage and avoid any risks, thereby protecting their babies from harm and put their children’s needs before their own – they should not allow toxins to enter the body. On the other hand, “responsible” women take and act on medical advice – they should take the medicine as directed by their health professional. This is the inherent conflict in medicine use for maternal bodies. Summary The increased complexity involved when one body’s actions impact the body of another – as in the pregnant and lactating body – has received little acknowledgment. We consider possibilities for future research and methodologies. We argue that considering the complexity of issues for maternal bodies can improve our

Ayurvedic medicine and anaesthesia

2011-01-01

Full Text Available The use of herbal medicines has increased dramatically over the past few years. The United States alone noted a 380% increase in the consumption of these products. Although the common practice of taking over-the-counter herbal soups, herbal teas and other such prepacked preparations was not associated with adverse events at large, still, some herbs are known to cause problems, especially when large doses are taken. The American Society of Anaesthesiologist (ASA has taken a conservative stance and recommended that it is prudent to stop these products at least 2-3 weeks prior to anaesthesia and surgery. This advice may be difficult to implement as most preoperative evaluations occur only a few days prior to surgery. Some of the Ayurvedic preparations have shown to improve the patient outcome when taken during the perioperative period. Hence, the conservative stance by ASA may not always benefit the patient. More scientific studies are needed to have more targeted recommendations. This article puts forward the facts that need to be addressed by researchers in the future.

This study was conducted to identify and describe the patients' perceptions of Islamic medicine based on gender, age, marital, educational level and working status among the Malaysian Muslim population. A nationwide interviewer-administered questionnaire survey was conducted in 2013. An open-ended questionnaire pertaining to Islamic medicine was used to increase the probability of capturing maximum data. This survey implemented a multistage design, stratified by state, proportionate to the size of the state population and was representative of the Malaysian population. Post-survey classification of results was performed accordingly. Complex data analysis was carried out using SPSS 16.0. The discussion was identified and categorised into various sections. The paper concludes that Islamic medicine has a major influence in the Malaysian Muslim community compared to other alternatives. Further, its potential for growth and importance especially for treating spiritual ailments cannot be denied. The respondents indicated that two factors motivate Islamic medicine in Malaysia: (1) the Muslim community opts for alternative healing because of their dissatisfaction with conventional methods; (2) Islamic medicine focuses only on healing spiritual-related problems. The average perception of respondents is that the function of Islamic medicine in healing physical diseases is undervalued and that it is not suitable to replace the functions of modern health institutions.

In the teeth of the evidence: the curious case of evidence-based medicine.

Science.gov (United States)

Davidoff, F

1999-03-01

For a very long time, evidence from research has contributed to clinical decision making. Over the past 50 years, however, the nature of clinical research evidence has drastically changed compared with previous eras: its standards are higher, the tools for assembling and analyzing it are more powerful, and the context in which it is used is less authoritarian. The consequence has been a shift in both the concept and the practice of clinical decision making known as evidence-based medicine. Evidence-based decisions, by definition, use the strongest available evidence, are often more quantitatively informed than decisions made in the traditional fashion; and sometimes run counter to expert opinion. The techniques of evidence-based medicine are also helpful in resolving conflicting opinions. Evidence-based medicine did not simply appear in vacuo; its roots extend back at least as far as the great French Encyclopedia of the 18th century, and the subsequent work of Pierre Louis in Paris in the early 19th century. The power of the evidence-based approach has been enhanced in recent years by the development of the techniques of systematic review and meta-analysis. While this approach has its critics, we would all want the best available evidence used in making decisions about our care if we got sick. It is only fair that the patients under our care receive nothing less.

A hybrid counter array device for counting events. The hybrid counter array includes a first counter portion comprising N counter devices, each counter device for receiving signals representing occurrences of events from an event source and providing a first count value corresponding to a lower order bits of the hybrid counter array. The hybrid counter array includes a second counter portion comprising a memory array device having N addressable memory locations in correspondence with the N counter devices, each addressable memory location for storing a second count value representing higher order bits of the hybrid counter array. A control device monitors each of the N counter devices of the first counter portion and initiates updating a value of a corresponding second count value stored at the corresponding addressable memory location in the second counter portion. Thus, a combination of the first and second count values provide an instantaneous measure of number of events received.

Counter-propagating beams have enabled the first stable three-dimensional optical trapping of microparticles and this procedure has been enhanced and developed over the years to achieve independent and interactive manipulation of multiple particles. In this work, we analyse counter-propagating shaped-beam traps that depart from the conventional geometry based on symmetric, coaxial counter-propagating beams. We show that projecting shaped beams with separation distances previously considered axially unstable can, in fact, enhance the axial and transverse trapping stiffnesses. We also show that deviating from using perfectly counter-propagating beams to use oblique beams can improve the axial stability of the traps and improve the axial trapping stiffness. These alternative geometries can be particularly useful for handling larger particles. These results hint at a rich potential for light shaping for optical trapping and manipulation using patterned counter-propagating beams, which still remains to be fully tapped

Design of an extended range long counter using super Monte Carlo simulation

Mazunga, Mohamed; Li, Taosheng; Li, Yanan; Hong, Bing; Wang, Yongfeng; Ji, Xiang

2017-01-01

We have designed an extended range neutron long counter on the basis of work optimized using SuperMC code. The problem of the existing traditional long counters is that their response function falls rapidly above 5 MeV. We proposed a new designed by adding two layers of converter material inside the polyethylene moderator. The relatively low density chromium and high density lead metals convert high energy neutron by (n, xn) spallation reaction. This produces more neutrons of lower energies, which have higher probability of being detected by thermal 3 He-counter. The response function at lower neutron energies was improved by inserting small polyethylene cylinder in front of 3 He counter. In this design we achieved to extent the flat response function of the long counter from few keV up to 150 MeV. The total fluctuation of response curve is less than ±9% over the entire energy range. The designed long counter is suitable to be used as neutron monitor for monitoring neutron fluence at high-energy neutron source. (authors)

A small end-window type gas-flow counter which has a sharpened needle (anode) against the end-window plane (cathode) was developed for low-level counting of β particles to the amount of less than one count per hour in solid sources of relatively high specific activity. The advantage of the needle counter for low-level work is that being of a conical shape the active volume as against the window area is small. The background count rate of 0.0092+-0.0005 cpm was obtained for a 10 mm dia needle counter operating in GM mode and in anticoincidence with a well-type NaI(Tl) guard crystal with massive shields. The counter design and the counter characteristics are presented in detail. The needle counter is simple in design, low-cost and stable in long time operation. (author)

300-MHz optical discriminator-counter

International Nuclear Information System (INIS)

Turko, B.; Lo, C.C.

1981-07-01

The prediction of future CO 2 content in the atmosphere is not completely credible because the oceanographers and terrestrial ecologists do not agree on the global CO 2 balance. Very precise measurements of O 2 /N 2 ratio using Raman scattering over a few years' period could provide important information and lead to the explanation of the disparity in the atmospheric CO 2 balance. An optical discriminator-counter has been developed to count closely spaced optical events in the few photon level. Simulated optical events as close as 2.5 ns apart had been positively detected by using selected photomultipliers and optimized discriminators. Testing of the optical discriminator-counter was done by using an electrical pulse pair spaced 3 ns apart and also by a similar optical pulse pair generated by fast light-emitting diode.

An acoustical bubble counter for superheated drop detectors

International Nuclear Information System (INIS)

Taylor, C.; Montvila, D.; Flynn, D.; Brennan, C.; D'Errico, F.

2006-01-01

A new bubble counter has been developed based on the well-established approach of detecting vaporization events acoustically in superheated drop detectors (SDDs). This counter is called the Framework Scientific ABC 1260, and it represents a major improvement over prior versions of this technology. By utilizing advanced acoustic pattern recognition software, the bubble formation event can be differentiated from ambient background noise, as well as from other acoustic signatures. Additional structural design enhancements include a relocation of the electronic components to the bottom of the device; thus allowing for greater stability, easier access to vial SDDs without exposure to system electronics. Upgrades in the electronics permit an increase in the speed of bubble detection by almost 50%, compared with earlier versions of the counters. By positioning the vial on top of the device, temperature and sound insulation can be accommodated for extreme environments. Lead shells can also be utilized for an enhanced response to high-energy neutrons. (authors)

To test the hypothesis that the number of publications in the field of physical medicine and rehabilitation (PMR) has increased over the last 16 years in a linear fashion, and to compare the trends in publication between the pediatric and adult literature. We evaluated all MEDLINE articles from January 1, 1998, to December 31, 2013, using Medical Subject Headings categories of rehabilitation. An age filter separated adult and pediatric articles. We divided articles into those with a low level of scientific evidence such as letters and editorials, and those with a high level of evidence such as controlled trials and meta-analyses. We used regression analysis to evaluate the effect of the year of publication on the number of publications of each type. Not applicable. Not applicable. Not applicable. Not applicable. MEDLINE reported a total of 98,501 adult publications and 30,895 pediatric publications during the evaluated period. There was a significant linear increase in the total number of publications in adult and pediatric rehabilitation publications with multiplication factors of 3.3 and 2.9, respectively. Importantly, publications with a high level of evidence showed larger multiplication factors compared with those with a low level of evidence (5.5 and 5.1 vs 2.1 and 2.0) for the adult and pediatric literature. The number of publications in the PMR field, especially those with a high level of scientific evidence, has increased linearly over the years, reflecting the rapid evolution of both adult and pediatric PMR.

We sought to understand gaps in reporting childhood TB cases among public and private sector health facilities (dubbed "non-NTP" facilities) outside the network of national TB control programmes, and the resulting impact of under-reporting on estimates of paediatric disease burden and market demand for new medicines. Exploratory assessments were carried out in Indonesia, Nigeria and Pakistan, reaching a range of facility types in two selected areas of each country. Record reviews and interviews of healthcare providers were carried out to assess numbers of unreported paediatric TB cases, diagnostic pathways followed and treatment regimens prescribed. A total of 985 unreported diagnosed paediatric TB cases were identified over a three month period in 2013 in Indonesia from 64 facilities, 463 in Pakistan from 35 facilities and 24 in Nigeria from 20 facilities. These represent an absolute additional annualised yield to 2013 notifications reported to WHO of 15% for Indonesia, 2% for Nigeria and 7% for Pakistan. Only 12% of all facilities provided age and sex-disaggregated data. Findings highlight the challenges of confirming childhood TB. Diagnosis patterns in Nigeria highlight a very low suspicion for childhood TB. Providers note the need for paediatric medicines aligned to WHO recommendations. This study emphasises the impact of incomplete reporting on the estimation of disease burden and potential market size of paediatric TB medicines. Further studies on "hubs" (facilities treating large numbers of childhood TB cases) will improve our understanding of the epidemic, support introduction efforts for new treatments and better measure markets for new paediatric medicines.

Proportional counter system for radiation measurement

Energy Technology Data Exchange (ETDEWEB)

Sugimoto, M; Okudera, S

1970-11-21

A gas such as Xe or Kr employed in counter tubes is charged into the counter tube of a gas-flow type proportional counter for radiation measurement and into a vessel having a volume larger than that of the counter tube. The vessel communicates with the counter tube to circulate the gas via a pump through both the vessel and tube during measurement. An organic film such as a polyester synthetic resin film is used for the window of the counter tube to measure X-rays in the long wavelength range. Accordingly, a wide range of X-rays can be measured including both long and short wavelengths ranges by utilizing only one counter tube, thus permitting the gases employed to be effectively used.

Human metabolic disease opens a new view to understanding the contribution of the intestinal microbiome to drug metabolism and drug-induced toxicity in gut-liver function. The gut microbiome, a key determinant of intestinal inflammation, also plays a direct role in chronic inflammation and liver disease. Gut bacterial communities directly metabolize certain drugs, reducing their bioavailability and influencing individual variation in drug response. In addition, some microbiome-produced compounds may affect drug pharmacokinetics and pharmacodynamics via altered expression of metabolizing enzymes and drug transporters or genes coding for drug target proteins, drug response phenotypes, and disease states. Molecular-based high-throughput technologies are providing novel insight about host-gut microbiome interactions, homeostasis, and xenobiotic effects associated with wide variation in efficacy or toxicity in humans. It is envisioned that future approaches to treating and preventing liver disease will benefit from in-depth studies of the liver-microbiome axis. Thus, the microbiome shares a fundamental role in human physiology with various organ systems, and its importance must be considered in the rapid evolution of precision medicine. A new emerging perspective of understanding the effect of the gut microbiome on human response to drugs would be indispensable for developing efficacious, safe, and cost-effective precision therapies. © 2017, The American College of Clinical Pharmacology.

The counter-guarantee may bean independent or accessory obligation, as the case may be, exclusively governed by its text, accordingto the parties’ will. At the same time, it is a complex juridical act, a contract whose contents cannot beset apart from the contracts connected form an “economic” point of view. The counter-guarantee is theresult of the banking practice and is generated by the need to make amends for the flaws generated bythe direct guarantee. The present research is focused on the analysis of the banking practice, normativeacts, jurisprudence and banking juridical literature.

Characterization of counter-rotating streamwise vortices in flat rectangular channel with one-sided wavy wall

KAUST Repository

Bouremel, Yann

2016-11-01

Particle Image Velocimetry (PIV) has been used to characterize the evolution of counter-rotating streamwise vortices in a rectangular channel with one sided wavy surface. The vortices were created by a uniform set of saw-tooth carved over the leading edge of a flat plate at the entrance of a flat rectangular channel with one-sided wavy wall. PIV measurements were taken over the spanwise and streamwise planes at different locations and at Reynolds number of 2500. Two other Reynolds numbers of 2885 and 3333 have also been considered for quantification purpose. Pairs of counter-rotating streamwise vortices have been shown experimentally to be centred along the spanwise direction at the saw-tooth valley where the vorticity ωz=0ωz=0. It has also been found that the vorticity ωzωz of the pairs of counter-rotating vortices decreases along the streamwise direction, and increases with the Reynolds number. Moreover, different quantifications of such counter-rotating vortices have been discussed such as their size, boundary layer, velocity profile and vorticity. The current study shows that the mixing due to the wall shear stress of counter-rotating streamwise vortices as well as their averaged viscous dissipation rate of kinetic energy decrease over flat and adverse pressure gradient surfaces while increasing over favourable pressure gradient surfaces. Finally, it was also demonstrated that the main direction of stretching is orientated at around 45° with the main flow direction.

[Romantic medicine in Germany as the philosophical explication for understanding the world and man - Mesmer and mesmerism].

Science.gov (United States)

Miodoński, L

2001-01-01

The turn of the 19th century was a rare period in history in which modernisation processes in human knowledge had brought about the rise of new scientific disciplines. They in turn considerably modified the traditional understanding of the world based on a metaphysical-esoteric mode. A multi-dimensional space was opened in research on nature, geography, history and culture as well as in the understanding of man and his spiritual structure. That period marked an important turning point in European thinking also because it expressed a kind of interparadigmatic state, wherein the theories of the old order were no longer applicable to swiftly changing reality. On the other hand, the symptoms of the new order displayed all the shortcomings of still underdeveloped, largely spontaneous attempts at understanding the world on the basis of new theoretical premises. At that time, German medicine, constantly in the process of seeking its theoretical and practical identity, became closely associated with the conceptual context and thinking structure of German idealism. That was an intellectual opposition against the rational and mechanistic model of the world which at the same time affirmed the philosophy of the absolute. In medical theory, it led to the emergence of new pursuits - studies on animal magnetism. Amid all the aberration of German romantic medicine (the ideologisation of and subordination to philosophical principles), its great achievement remains the discovery and attempt to describe areas of man's unconscious existence.

Medicine use as a strategy for coping with daily stressors is an under-studied issue. Studies show that stress is associated with use of over-the-counter medicine, but the underlying mechanisms are not well understood. The aim of this study was to examine whether sense of coherence (SOC) modifies the association between perceived stress and medicine use for headache. National cross-sectional study in Denmark. men and women aged 25-44 years, n = 990. The survey was conducted by web-based questionnaires and telephone interviews. The outcome measure was medicine use for headache. The independent variable was perceived stress. SOC and gender were investigated as moderators. Social class, headache prevalence and severity, and response method were included as co-variates. Our study showed that SOC modified the association between stress and medicine use for headache (only statistically significant among women). The odds for medicine use among women who felt stressed were 2.30 (1.39-3.79) compared to women who did not feel stressed; among men who felt stressed the equivalent odds were 1.46 (0.80-2.66). In analysis stratified by SOC, the odds for medicine use when stressed were 2.09 (0.71-6.21) among women with high SOC, 2.21 (1.10-4.41) among women with medium SOC and 3.69 (1.09-12.47) among women with low SOC. The equivalent odds for men were 1.29 (0.33-5.04), 1.33 (0.59-3.04) and 2.47 (0.57-10.64), respectively. SOC modifies the association between stress and medicine use especially among women. Individuals with fewer coping resources may be more likely to use medicine beyond indication to treat stress.

Full Text Available BACKGROUND: In Latin American countries over-the-counter (OTC dispensing of antibiotics is common. In 2010, both Mexico and Brazil implemented policies to enforce existing laws of restricting consumption of antibiotics only to patients presenting a prescription. The objective of the present study is therefore to evaluate the impact of OTC restrictions (2010 on antibiotics consumption in Brazil and Mexico. METHODS AND FINDINGS: Retail quarterly sales data in kilograms of oral and injectable antibiotics between January 2007 and June 2012 for Brazil and Mexico were obtained from IMS Health. The unit of analysis for antibiotics consumption was the defined daily dose per 1,000 inhabitants per day (DDD/TID according to the WHO ATC classification system. Interrupted time series analysis was conducted using antihypertensives as reference group to account for changes occurring independently of the OTC restrictions directed at antibiotics. To reduce the effect of (a seasonality and (b autocorrelation, dummy variables and Prais-Winsten regression were used respectively. Between 2007 and 2012 total antibiotic usage increased in Brazil (from 5.7 to 8.5 DDD/TID, +49.3% and decreased in Mexico (10.5 to 7.5 DDD/TID, -29.2%. Interrupted time series analysis showed a change in level of consumption of -1.35 DDD/TID (p<0.01 for Brazil and -1.17 DDD/TID (p<0.00 for Mexico. In Brazil the penicillins, sulfonamides and macrolides consumption had a decrease in level after the intervention of 0.64 DDD/TID (p = 0.02, 0.41 (p = 0.02 and 0.47 (p = 0.01 respectively. While in Mexico it was found that only penicillins and sulfonamides had significant changes in level of -0.86 DDD/TID (p<0.00 and -0.17 DDD/TID (p = 0.07. CONCLUSIONS: Despite different overall usage patterns of antibiotics in Brazil and Mexico, the effect of the OTC restrictions on antibiotics usage was similar. In Brazil the trend of increased usage of antibiotics was tempered after the OTC restrictions; in

A method for fabrication of highly transparent platinum counter electrodes (CEs) has been developed based on spray coating of Pt nanoparticles (NPs) on hot substrates. This method leads to 86% reduction in Pt consumption reducing the Pt cost per peak watt of counter electrode from $0.79/Wp down to $0.11/Wp compared to the conventional Pt counter electrodes made by sputter deposition. The simplicity and low cost of this method provide a basis for an up-scalable fabrication process. The Pt NP layer is over 88% transparent, leading to overall transparency of 80% when incorporated with indium tin oxide/glass substrates for functional counter electrodes. This counter electrode exhibits a large surface area and high catalytic activity, comparable to that of the conventional opaque CEs. Semi-transparent dye-sensitized solar cells fabricated based on this counter electrode showed 6.17% power conversion efficiency. - Highlights: • Counter electrode (CE) prepared by spraying nanoparticle (NP) Pt on hot substrate. • Low cost and scalable fabrication process of CE. • The spray deposited CE uses 10 times less Pt compared to the sputtering method. • The CE is 80% transparent and exhibits a large surface and high catalytic activity. • A semitransparent dye-sensitized solar cell with Pt NP CE was 6.17% efficient.

Patients and methods: The study included 170 people, inhabitants of Bialystok aged over 60: 85 students of the University of a Healthy Senior and the University of Psychogeriatric Prophylaxis, and 85 students of the University of the Third Age in Bialystok. The study made use of a diagnostic survey conducted via a questionnaire prepared by the authors. Results: The vast majority of respondents bought OTC drugs for own use. About one-third of the respondents from each analyzed group bought OTC drugs less often than once every 3 months. Over half of the respondents bought OTC drugs due to a cold. A majority of the respondents were of the opinion that OTC drugs should be sold only in pharmacies. Over 40% of seniors took 1 OTC drug regularly. Most respondents also took vitamins and supplements. The main sources of information on OTC drugs for the studied seniors were their doctor and pharmacist. Respondents did not always consult the treatment method with a doctor or pharmacist. Over half of the respondents familiarized themselves with the contents of the OTC drug package leaflet. Over three-quarters of the respondents were familiar with drug disposal methods; however, despite declarations of being familiar with these principles, a significant percentage did not bring back medication to a pharmacy or clinic, or threw the drugs

We have systematically identified medicinal products withdrawn worldwide because of adverse drug reactions, assessed the level of evidence used for making the withdrawal decisions, and explored the patterns of withdrawals over time. We searched PubMed, the WHO database of withdrawn products, and selected texts. We included products that were withdrawn after launch from 1950 onwards, excluding non-human and over-the-counter medicines. We assessed the levels of evidence on which withdrawals were based using the Oxford Center for Evidence Based Medicine Levels of Evidence. Of 353 medicinal products withdrawn from any country, only 40 were withdrawn worldwide. Anecdotal reports were cited as evidence for withdrawal in 30 (75%) and deaths occurred in 27 (68%). Hepatic, cardiac, and nervous system toxicity accounted for over 60% of withdrawals. In 28 cases, the first withdrawal was initiated by the manufacturer. The median interval between the first report of an adverse drug reaction that led to withdrawal and the first withdrawal was 1 year (range 0-43 years). Worldwide withdrawals occurred within 1 year after the first withdrawal in any country. In conclusion, the time it takes for drugs to be withdrawn worldwide after reports of adverse drug reactions has shortened over time. However, there are inconsistencies in current withdrawal procedures when adverse drug reactions are suspected. A uniform method for establishing worldwide withdrawal of approved medicinal products when adverse drug reactions are suspected should be developed, to facilitate global withdrawals. Rapid synthesis of the evidence on harms should be a priority when serious adverse reactions are suspected.

To evaluate the current management of over-the-counter (OTC) insomnia complaints in Australian community pharmacies using standardized patient methodology. Trained standardized patients visited a sample of 100 randomly selected South East Queensland community pharmacies in June 2011. The standardized patients enacted two OTC insomnia scenarios: a direct product request (DPR) (n = 50) and a symptom-based request (SBR) (n = 50). Results of the interactions were documented immediately after each visit and evaluated using the Pharmaceutical Society of Australia's WHAT STOP GO protocol as a standard comparison. Of all DPRs, 30% were handled entirely by the pharmacist, 70% of staff enquired about specific symptoms and 28% investigated the cause of insomnia. No staff investigated the frequency of product use. The DPR scenario resulted in a 92% supply of the requested doxylamine product (Restavit). In the SBR scenario, 18% of requests were handled entirely by the pharmacist, 58% of staff enquired about specific symptoms and 44% investigated the cause of insomnia. Staff recommended medicated products (38%), or herbal (78%) or non-drug techniques (18%). Investigation into smoking and alcohol intake was not undertaken in DPR or SBR interactions, while questioning on caffeine intake was undertaken in 2 and 14% of cases respectively. There were no significant differences found in the handling of sleep requests by pharmacists compared to pharmacy assistants. The standardized patient methodology was a successful way to assess the community pharmacy counselling provided with OTC sleep requests and suboptimal staff responses were found when compared with recommended practice standards. © 2013 Royal Pharmaceutical Society.

Age-dating groundwater and seawater using the 39 Ar/Ar ratio is an important tool to understand water mass-flow rates and mean residence time. Low-background proportional counters developed at Pacific Northwest National Laboratory use mixtures of argon and methane as counting gas. We demonstrate sensitivity to 39 Ar by comparing geological (ancient) argon recovered from a carbon dioxide gas well and commercial argon. The demonstrated sensitivity to the 39 Ar/Ar ratio is sufficient to date water masses as old as 1000 years. - Highlights: • 39 Ar/Ar age dating is important for understanding environmental water migration. • Ultra low background proportional counters have been developed. • 39 Ar is detected in atmospheric argon at a rate of 70.3 counts per day. The demonstrated background is 166 counts per day. • Age dating is possible for water with underground residence time of up to 1000 years.

MicroRNA-Mediated Gene Silencing in Plant Defense and Viral Counter-Defense

Directory of Open Access Journals (Sweden)

Sheng-Rui Liu

Full Text Available MicroRNAs (miRNAs are non-coding RNAs of approximately 20–24 nucleotides in length that serve as central regulators of eukaryotic gene expression by targeting mRNAs for cleavage or translational repression. In plants, miRNAs are associated with numerous regulatory pathways in growth and development processes, and defensive responses in plant–pathogen interactions. Recently, significant progress has been made in understanding miRNA-mediated gene silencing and how viruses counter this defense mechanism. Here, we summarize the current knowledge and recent advances in understanding the roles of miRNAs involved in the plant defense against viruses and viral counter-defense. We also document the application of miRNAs in plant antiviral defense. This review discusses the current understanding of the mechanisms of miRNA-mediated gene silencing and provides insights on the never-ending arms race between plants and viruses.

HOW THE WAR WAS ‘ONE’: COUNTERING VIOLENT EXTREMISM AND THE SOCIAL DIMENSIONS OF COUNTER-TERRORISM IN CANADA.

Tami Amanda Jacoby

2016-03-01

Full Text Available The current global “war on terror” highlights a fundamental quandary for all liberal democracies seeking to counter the violent extremism of their own citizens while maintaining civic rights and freedoms. This challenge accompanies a transformation in international conflict from inter-state war and superpower rivalry, to homegrown terrorism, radicalization-to-violence, Internet propaganda, and targeting and recruitment of vulnerable persons. These new threats shift the battlefield, as traditionally defined, to the home front, as extremist violence is nurtured by and perpetrated within public spaces, such as schools, places of religious worship, civil society and the home. Today, violence emanates from within liberal democratic society and its extremist motivations bypass the very institutions that would otherwise support civic rights, freedoms and multiculturalism. As such, attempts to counter extremist violence must appeal to the political, social, cultural, religious and familial aspects of human behavior alongside a parallel shift in efforts to keep citizens safe within their own social spaces. In recent years, Canada has been introduced to home grown and lone individual terrorism with the cases of attack against armed forces personnel in Saint-Jean-sur-Richelieu and Ottawa in 2014. This article identifies the social dimensions of counter-terrorism in the Canadian context, a propitious case by which to evaluate different approaches to countering violent extremism. Canadian initiatives - simultaneously proliferating and in their infancy – raise a host of questions about counter-terrorism in liberal democratic countries. For example, why do individuals radicalize-to-violence in rights-based and multicultural societies? How and when can the liberal democratic state best temper the radicalization process in ways that are effective and procedurally just? What state-society balance works best to counter radicalized viewpoints? Who are the

Full Text Available Objective: This study aimed to produce current data regarding behavioural aspects of non-prescription (over-the-counter medicine purchases, in light of changes in the pharmaceutical market and increasing provision of professional services in pharmacies.Methods: Data were collected in 15 community pharmacies in South-East Queensland, Australia, over 540 hours in five days in August, 2006. The method, previously validated, involved documentation of both observational and interview data. Fifteen trained researchers were stationed in a selected pharmacy each to unobtrusively observe all eligible sales of non-prescription medicines, and, where possible, interview the purchasers post-sale. Non-response was supplemented by observational data and recall by the salesperson. The data included details of the purchase and purchasing behaviour, while new questions addressed issues of topical importance, including customers’ privacy concerns. A selection of the analyses is reported here.Results: In total, 3470 purchases were documented (135-479 per pharmacy, with customers of 67.5% of purchases (74.7% excluding an outlier pharmacy participating in the survey. Customers averaged 1.2 non-prescription medicines per transaction. Two-thirds (67.2% of customers were female, and 38.8% of the customers were aged 31-45 years. Analgesics and respiratory medicines accounted for two-thirds of the sales data (33.4% and 32.4%, respectively. Intended-brand purchases comprised 71% of purchases (2004/2824; in-store substitution then occurred in 8.8% of these cases, mainly following recommendations by pharmacy staff.

In this work, a simple and efficient protocol for the rapid separation of two pairs of isomeric monoterpenes from Paeoniae Alba Radix was developed by combining macroporous resin and elution-extrusion counter-current chromatography. The crude extract was firstly subjected to a D101 macroporous resin column eluted with water and a series of different concentrations of ethanol. Then, effluents of 30 and 95% ethanol were collected as sample 1 and sample 2 for further counter-current chromatography purification. Finally, a pair of isomers, 96 mg of compound 1 and 48 mg of compound 2 with purities of 91.1 and 96.2%, respectively, was isolated from 200 mg of sample 1. The other pair of isomers, 14 mg of compound 3 and 8 mg of compound 4 with purities of 93.6 and 88.9%, respectively, was isolated from 48 mg of sample 2. Their purities were analyzed by high-performance liquid chromatography, and their chemical structures were identified by mass spectrometry and (1) H NMR spectroscopy. Compared to a normal counter-current chromatography separation, the separation time and solvent consumption of elution-extrusion counter-current chromatography were reduced while the resolutions were still good. The established protocol is promising for the separation of natural products with great disparity of content in herbal medicines. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Pacific Northwest National Laboratory has designed and constructed a prototype portable neutron coincidence counter intended for use in a variety of applications, such as the verification and inspection of weapons components, safety measurements for novel and challenging situations, portable portal deployment to prevent the transportation of fissile materials, uranium enrichment measurements in hard-to-reach locations, waste assays for objects that cannot be measured by existing measurement systems, and decontamination and decommissioning. The counting system weighs less than 40 kg and is composed of parts each weighing no more than 5 kg. In addition, the counter`s design is sufficiently flexible to allow rapid, reliable assembly around containers of nearly arbitrary size and shape. The counter is able to discern the presence of 1 kg of weapons-grade plutonium within an ALR-8 (30-gal drum) in roughly 100 seconds and 10 g in roughly 1000 seconds. The counter`s electronics are also designed for maximum adaptability, allowing operation under a wide variety of circumstances, including exposure to gamma-ray fields of 1 R/h. This report provides a detailed review of the design and construction process. Finally, preliminary experimental measurements that confirm the performance capabilities of this counter are discussed. 6 refs., 18 figs., 3 tabs.

The field of evolutionary medicine uses evolutionary principles to understand changes in human anatomy and physiology that have occurred over time in response to environmental changes. Through this evolutionary-based approach, we can understand disease as a consequence of anatomical and physiological "trade-offs" that develop to facilitate survival and reproduction. We demonstrate how diachronic study of human anatomy and physiology is fundamental for an increased understanding of human health and disease. ©2016 Int. Union Physiol. Sci./Am. Physiol. Soc.

Full text: Nuclear medicine has contributed to notable benefits to the human health from the very beginning. The Radioisotopes techniques, as well as the ionizing radiation used, have evolved providing functional and anatomical information of the patient, through non-invasive methods. With reference to Radiological Protection, the justification of each one of these practices and its perfect execution is intimately related to the benefit provided to the patients. The National Atomic Energy Commission apart from favouring the scientific and technological development, considers indispensable to work thoroughly on the professional training of the prospective technologists. Our over twenty-year experience in organizing and delivering courses of Technologists in Nuclear Medicine, although based on a much simpler program, have allowed the Institute of Nuclear Studies of the Ezeiza Atomic Center to acquire the capacity of developing a program to train highly qualified Technologists in that field. This project represents a step forward of great importance to the graduates qualification, since they will have the endorsement of CNEA and of the Faculty of Medicine of the Maimonides University. These are the three outstanding characteristics agreed on: 1.- General Education, carried out by subjects closely related to the optimisation of the relation Technologist - Patient - Environment and represented by: Radiological Protection and Hospital Security, Psychology, Ethics and Professional Medical Ethics, Nursing, English, Hygiene and Hospital Security and Management of the Quality in Services of Health. 2.- Diagnostic Procedures: planned according to organs, apparatuses or systems which are horizontally crossed by the anatomy, physiology and physiopathology Preparation of the patient, indications, main counter indications, radiopharmaceuticals, mechanisms of incorporation, pathologies, clinical protocols, instrumentation, post radiopharmaceuticals administration imaging

Clinical trials were carried out in co-operation with the Nuclear Medicine Department of the Teaching Hospital, of MULTIGAMMA 1260 by LKB WALLAC, Finland, an instrument for gamma counting of samples in RIA. The experience is summed up gained with the operation of the instrument, a brief description is presented and a comparison is given with the NE 1612 multidetector instrument and a conventional automatic single-detector gamma counter by Searle which has been used for some time in routine operation. The major advantage of the instrument being tested is its high speed evaluation given by the simultaneous measurement of 12 samples and immediate processing of the results by a microprocessor unit. Concentration values are printed out immediately after the last point of the curve has been measured, calculated and plotted. The accuracy, efficiency and stability of measurement at this high speed remains comparable to conventional instruments. (author)

Water and counter-hegemony: Kurdish struggle in the Tigris and Euphrates in Turkey

Directory of Open Access Journals (Sweden)

Gilberto Conde

2017-01-01

Full Text Available Water issues are often related to general questions of justice. This article discusses Tigris and Euphrates water issues from the point of view of Kurds in Turkey. The goal here is not to discuss the entire landscape of power relations and interests in the recent history of these rivers inside the country or across borders, but to understand how opposition Kurds view the way in which Turkish authorities manage water resources, policies and politics within the basins, affecting local society and the environment. It has been found that beyond establishing hydro-hegemony over co-riparian states along the Tigris and Euphrates (Syria and Iraq, the Turkish state has sought to deploy its soft and hard power over Kurds. The opposition Kurdish movement has responded by developing its own counter-hegemonic measures. Their proposals seem to aim at winning over Kurds, but also Turks and other peoples. Their framing of a different type of stakeholder participation in decision-making calls for a model of direct democracy covering different aspects of life, including water management and environmental soundness. The research is based on academic and government literature and a number of semi-structured interviews with Kurdish municipal officials, faculty and activists.

Health consumers increasingly want access to accurate, evidence-based information about their medications. Currently, education about medications (that is, information that is designed to achieve health or illness related learning) is provided predominantly via spoken communication between the health provider and consumer, sometimes supplemented with written materials. There is evidence, however, that current educational methods are not meeting consumer needs. Multimedia educational programs offer many potential advantages over traditional forms of education delivery. To assess the effects of multimedia patient education interventions about prescribed and over-the-counter medications in people of all ages, including children and carers. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2011, Issue 6), MEDLINE (1950 to June 2011), EMBASE (1974 to June 2011), CINAHL (1982 to June 2011), PsycINFO (1967 to June 2011), ERIC (1966 to June 2011), ProQuest Dissertation & Theses Database (to June 2011) and reference lists of articles. Randomised controlled trials (RCTs) and quasi-RCTs of multimedia-based patient education about prescribed or over-the-counter medications in people of all ages, including children and carers, if the intervention had been targeted for their use. Two review authors independently extracted data and assessed the risk of bias of included studies. Where possible, we contacted study authors to obtain missing information. We identified 24 studies that enrolled a total of 8112 participants. However, there was significant heterogeneity in the comparators used and the outcomes measured, which limited the ability to pool data. Many of the studies did not report sufficient information in their methods to allow judgment of their risk of bias. From the information that was reported, three of the studies had a high risk of selection bias and one was at high risk of bias due to lack of blinding of the outcome

GENE-counter is a complete Perl-based computational pipeline for analyzing RNA-Sequencing (RNA-Seq) data for differential gene expression. In addition to its use in studying transcriptomes of eukaryotic model organisms, GENE-counter is applicable for prokaryotes and non-model organisms without an available genome reference sequence. For alignments, GENE-counter is configured for CASHX, Bowtie, and BWA, but an end user can use any Sequence Alignment/Map (SAM)-compliant program of preference. To analyze data for differential gene expression, GENE-counter can be run with any one of three statistics packages that are based on variations of the negative binomial distribution. The default method is a new and simple statistical test we developed based on an over-parameterized version of the negative binomial distribution. GENE-counter also includes three different methods for assessing differentially expressed features for enriched gene ontology (GO) terms. Results are transparent and data are systematically stored in a MySQL relational database to facilitate additional analyses as well as quality assessment. We used next generation sequencing to generate a small-scale RNA-Seq dataset derived from the heavily studied defense response of Arabidopsis thaliana and used GENE-counter to process the data. Collectively, the support from analysis of microarrays as well as the observed and substantial overlap in results from each of the three statistics packages demonstrates that GENE-counter is well suited for handling the unique characteristics of small sample sizes and high variability in gene counts.

Smith, David K.

2005-03-01

This article focuses on the essential roles played by intermolecular forces in mediating the interactions between chemical molecules and biological systems. Intermolecular forces constitute a key topic in chemistry programs, yet can sometimes seem disconnected from real-life applications. However, by taking a "supramolecular" view of medicinal chemistry and focusing on interactions between molecules, it is possible to come to a deeper understanding of recent developments in medicine. This allows us to gain a real insight into the interface between biology and chemistry—an interdisciplinary area that is crucial for the development of modern medicinal products. This article emphasizes a conceptual view of medicinal chemistry, which has important implications for the future, as the supramolecular approach to medicinal-chemistry products outlined here is rapidly allowing nanotechnology to converge with medicine. In particular, this article discusses recent developments including the rational design of drugs such as Relenza and Tamiflu, the mode of action of vancomycin, and the mechanism by which bacteria develop resistance, drug delivery using cyclodextrins, and the importance of supramolecular chemistry in understanding protein aggregation diseases such as Alzheimer's and Creutzfield Jacob. The article also indicates how taking a supramolecular approach will enable the development of new nanoscale medicines.

Fibrotic lung diseases involve subject-environment interactions, together with dysregulated homeostatic processes, impaired DNA repair and distorted immune functions. Systems medicine-based approaches are used to analyse diseases in a holistic manner, by integrating systems biology platforms along with clinical parameters, for the purpose of understanding disease origin, progression, exacerbation and remission.Interstitial lung diseases (ILDs) refer to a heterogeneous group of complex fibrotic diseases. The increase of systems medicine-based approaches in the understanding of ILDs provides exceptional advantages by improving diagnostics, unravelling phenotypical differences, and stratifying patient populations by predictable outcomes and personalised treatments. This review discusses the state-of-the-art contributions of systems medicine-based approaches in ILDs over the past 5 years. Copyright ©ERS 2017.

This patent specification describes a radiation counter utilizing at least one detector for sensing radiation from a living body. The radiation counter also includes an aperture for forming a corridor between the body and the detector. A shield outside the corridor prevents passage of background radiation through the corridor and gaining access to the detector. The counter also includes a device for isolating a selected portion of the body from the corridor such that radiation counting is restricted to a region of the body through a separate detector. The corridor formation permits a user to stand in an upright position while the detector and detectors are able to separately monitor different sections of the body. The radiation counter overcomes the problem of obtaining accurate and quick measurements or radiation doses sustained by a large group of persons. (author)

Diercke, A.; Kuckein, C.; Verma, M.; Denker, C.

Aim. The giant solar filament was visible on the solar surface from 2011 November 8-23. Multiwavelength data from the Solar Dynamics Observatory (SDO) were used to examine counter-streaming flows within the spine of the filament. Methods: We use data from two SDO instruments, the Atmospheric Imaging Assembly (AIA) and the Helioseismic and Magnetic Imager (HMI), covering the whole filament, which stretched over more than half a solar diameter. Hα images from the Kanzelhöhe Solar Observatory (KSO) provide context information of where the spine of the filament is defined and the barbs are located. We apply local correlation tracking (LCT) to a two-hour time series on 2011 November 16 of the AIA images to derive horizontal flow velocities of the filament. To enhance the contrast of the AIA images, noise adaptive fuzzy equalization (NAFE) is employed, which allows us to identify and quantify counter-streaming flows in the filament. We observe the same cool filament plasma in absorption in both Hα and EUV images. Hence, the counter-streaming flows are directly related to this filament material in the spine. In addition, we use directional flow maps to highlight the counter-streaming flows. Results: We detect counter-streaming flows in the filament, which are visible in the time-lapse movies in all four examined AIA wavelength bands (λ171 Å, λ193 Å, λ304 Å, and λ211 Å). In the time-lapse movies we see that these persistent flows lasted for at least two hours, although they became less prominent towards the end of the time series. Furthermore, by applying LCT to the images we clearly determine counter-streaming flows in time series of λ171 Å and λ193 Å images. In the λ304 Å wavelength band, we only see minor indications for counter-streaming flows with LCT, while in the λ211 Å wavelength band the counter-streaming flows are not detectable with this method. The diverse morphology of the filament in Hα and EUV images is caused by different absorption

Strategic and tactical planning for military intervention needs revision as the causes, methods, and means of conflict have evolved. Counter-insurgent engagement is one such intervention that governments, militaries, and non-governmental organizations seek to better understand. Modeling insurgencies is an acceptable means to gain insight into the various characteristics of asymmetric warfare to proffer prescriptive resolutions for mitigating their effects. Colombia's insurgency poses the challenge of assessing population behavior in a non-traditional revolutionary climate. Factors prevalent in traditional insurgency are not applicable in Colombia, specifically between the years 1993 and 2001 with the democratization of the drug cartels. The catastrophic events of September 11th reverberated in Colombia resulting in a new policy and strategy to the waging the counter-insurgency there. This research introduces a structured methodology to modeling the Colombian counter-insurgency incorporating qualitative assessment, mathematical representation, and a System Dynamics approach to represent the effects of the policy change.

2002-01-01

The reliability of GM counter tubes should be described by useful time before failure-life and failure rate during life. A new method to study the failure regularity of GM counter tubes is advanced and adopted. The essential point of the method is that after the GM counter tubes of the instruments in use is tested, both the performance parameters and other information of the GM counter tubes and the instruments collected are recorded. Then database is created. Failure criterion is ascertained. The GM counter tubes are inspected to determine whether they are failure. Failure mode should be decided if the GM counter tubes failure. The GM counter tubes with the same useful year come together to make up a subsample. According to the relevant information, the number of the subsample is restored to the number of the sample that initially put into use. Then the number of failure sample is counted and at the same time the distribution of failure mode is got. The parameter m, γ, t 0 of Weibull distribution function are calculated with method of linear fit. Thus mean life, failure rate and other character values are obtained. Using this method, useful life and failure rate are determined. The conclusion is that the useful life is 18-20 years and the failure rate is 5 x 10 -6 and 4 x 10 -6 /h respectively during the course

Globally, traditional medicine has long been used to address relatively common illness, mental ill health and during childbirth and post-natal care. However, traditional medicine is primarily provided by the private sector and it is unclear how far expenditures on traditional medicine contribute to household impoverishment. A life history method was used to understand the health seeking experience of 24 households over the last 60 years in Cambodia, a country with high out-of-pocket expenditures for health. The life histories suggest that traditional medicine in Cambodia has been undergoing a process of commercialization, with significant impacts on poor households. In the earlier lives of respondents, payments for traditional medicine were reported to have been flexible, voluntary or appropriate to patients' financial means. In contrast, contemporary practitioners appear to seek immediate cash payments that have frequently led to considerable debt and asset sales by traditional medicine users. Given traditional medicine's popularity as a source of treatment in Cambodia and its potential to contribute to household impoverishment, we suggest that it needs to be included in a national conversation about achieving Universal Health Coverage in the country. © The Author 2017.

We evaluated the effectiveness of a policy allowing for the sale of over-the-counter drugs outside of pharmacies by examining its effect on number of monthly outpatient visits for acute upper respiratory infections, dyspepsia, and migraine. We used medical claims data extracted from the Korean National Health Insurance Cohort Database from 2009 to 2013. The Korean National Health Insurance Cohort Database comprises a nationally representative sample of claims - about 2% of the entire population - obtained from the medical record data held by the Korean National Health Insurance Corporation (which has data on the entire nation). The analysis included26,284,706 person-months of 1,042,728 individuals. An interrupted-time series analysis was performed. Outcome measures were monthly outpatient visits for acute upper respiratory infections, dyspepsia, and migraine. To investigate the effect of the policy, we compared the number of monthly visits before and after the policy's implementation in 2012. For acute upper respiratory infections, monthly outpatient visits showed a decreasing trend before the policy (ß = -0.0003);after it, a prompt change and increasing trend in monthly outpatient visits were observed, but these were non-significant. For dyspepsia, the trend was increasing before implementation (ß = -0.0101), but this reversed after implementation(ß = -0.007). For migraine, an increasing trend was observed before the policy (ß = 0.0057). After it, we observed a significant prompt change (ß = -0.0314) but no significant trend. Deregulation of selling over-the-counter medication outside of pharmacies reduced monthly outpatient visits for dyspepsia and migraine symptoms, but not acute upper respiratory infections.

A Neutron Rem Counter

Energy Technology Data Exchange (ETDEWEB)

Andersson, I Oe; Braun, J

1964-01-15

A neutron detector is described which measures the neutron dose rate in rem/h independently of the energy of the neutrons from thermal to 15 MeV. The detector consists of a BF{sub 3} proportional counter surrounded by a shield made of polyethylene and boron plastic that gives the appropriate amount of moderation and absorption to the impinging neutrons to obtain rem response. Two different versions have been developed. One model can utilize standard BF{sub 3} counters and is suitable for use in installed monitors around reactors and accelerators and the other model is specially designed for use in a portable survey instrument. The neutron rem counter for portable instruments has a sensitivity of 2.4 cps/mrem/h and is essentially nondirectional in response. With correct bias setting the counter is insensitive to gamma exposure up to 200 r/h from Co-60.

2009-01-01

Iodine-131 is frequently used in nuclear medicine services for diagnosis and therapy of thyroid diseases. Furthermore, the Nuclear Technology Development Centre (CDTN/CNEN), in Belo Horizonte, uses Iodine-131 for radiobiology and radiopharmacy researches. The increasing use of this radionuclide for medical and research purposes as well as its high volatility creates a demand for feasible methodologies to perform occupational control of internal contamination. Therefore the objective this work is to develop methods of in vivo bioassay for evaluation Iodine-131 incorporation by using NaI(Tl) 6'' x 4'' scintillation detector of the CDTN-Whole Body Counter (WBC). Such detector was calibrated for in vivo measurements with a neck-thyroid phantom, simulating Iodine-131 incorporation. The chosen counting geometry was lying under monitoring bed of CDTNWBC. A methodology for bioassay data interpretation, based on standard ICRP 56 model was established with software AIDE (activity internal dose estimate) version 6.0. It was concluded that in vivo measurements have sufficient sensitivity for the monitoring of Iodine-131 through CDTN-Whole Body Counter. Therefore, the CDTN-Whole Body Counter equipment of Belo Horizonte are ready to attend suspicion intake cases of Iodine- 131 (author)

The guidelines for microdosing in clinical trials were published in Japan in 2008 following the guidelines of the European Medicines Agency and the Food and Drug Administration. They recommend utilizing accelerator mass spectrometry (AMS) and positron emission tomography as candidates for monitoring drug metabolites in preclinical studies. We correlate the two methods by measuring appropriately labeled tissue samples from various mouse organs using both AMS and gamma counter. First, we measured the 14 C background levels in mouse organs using the AMS system. We then clarified the relationship between AMS and gamma counter by simultaneously administering 14 C-2-fluoro-2-deoxyglucose ( 14 C-FDG) and 18 F-2-fluoro-2-deoxyglucose ( 18 F-FDG). Tissue distribution was examined after 30 min, 1 h, 2 h and 4 h using the AMS system for 14 C-FDG and gamma counter for 18 F-FDG. Background 14 C levels were subtracted from the data obtained with radiotracer administration. The background 14 C concentration differed with tissue type measured. Background 14 C concentration in mouse liver was higher than in other organs, and was approximately 1.5-fold that in blood. The correlation coefficient (r) of the measurements between AMS ( 14 C-FDG) and gamma counter ( 18 F-FDG) was high in both normal (0.99 in blood, 0.91 in brain, 0.61 in liver and 0.78 in kidney) and tumor-bearing mice (0.95 in blood and 0.99 in tumor). The clearance profile of 18 F-FDG was nearly identical to that of 14 C-FDG measured with AMS. Accelerator mass spectrometry analysis has an excellent correlation with biodistribution measurements using gamma counter. Our results suggest that the combination of AMS and positron emission tomography (PET) can act as a complementary approach to accelerate drug development. (author)

Real-time aerosol photometer and optical particle counter comparison

The paper presents the results of a comparison exercise among real-time aerosol samplers, based on different light scattering techniques. The comparison was carried out near to the ISAC institute in a box positioned inside the CNR research area in Bologna. Two nephelometers (Dust Trak from TSI, and Air Genius from Unitec) and an optical particle counter (ENVIRO-check from Grimm) were used for P M1 and P M10 fraction assessment. In the case of the optical particle counter, the particle number concentration in each size bin was also used. In parallel, two manual sampling lines were employed for reference (gravimetric) measurements. The results highlight different factor scales for the dust monitors, in comparison with gravimetric assessment, underlining the importance of a user calibration of such monitors as a function of the specific aerosol sampled. Moreover, the relative fluctuations of the hourly P M 10 and P M1 concentrations, against daily average concentrations, were studied in order to compare the ability of each sampler to follow changes in the aerosol size distribution. It was found that the photometers and optical particle counter revealed different behaviours. In the latter, a small increase in the particle concentration number in the coarse fraction gave a relatively high increase in the mass concentration that was not measured by the photometers. The explanation could be the relatively slight influence of a small particle number variation on the total scattered light for the photometers, unlike the case of the optical particle counter, where each particle contributes to the mass concentration. This aspect merits future research in order to better understand optical particle counter output used in P Mx monitoring activities.

Data analysis focused on semi-structured, open-ended interviews with 44 participants, interviewed 3-5 times each over the course of a study evaluating Traditional Chinese Medicine (TCM) for temporomandibular disorders (TMD), a form of chronic orofacial pain. Transcripts were coded and analyzed using qualitative and ethnographic methods. A "Modes of Hoping" (Webb, 2007)(1) framework informed our analysis. Five modes of hoping emerged from participant narratives: Realistic Hope, Wishful Hope, Utopian Hope, Technoscience Hope, and Transcendent Hope. Using this framework, hope is demonstrated as exerting a profound influence over how participants assess and report their expectations. This suggests that researchers interested in measuring expectations and understanding their role in treatment outcomes should consider hope as exercising a multi-faceted and dynamic influence on participants' reporting of expectations and their experience and evaluation of treatment.

We propose a new architecture of an integrated time interval counter that provides its permanent calibration in the background. Time interval measurement and the calibration procedure are based on the use of a two-stage interpolation method and parallel processing of measurement and calibration data. The parallel processing is achieved by a doubling of two-stage interpolators in measurement channels of the counter, and by an appropriate extension of control logic. Such modification allows the updating of transfer characteristics of interpolators without the need to break a theoretically infinite measurement session. We describe the principle of permanent calibration, its implementation and influence on the quality of the counter. The precision of the presented counter is kept at a constant level (below 20 ps) despite significant changes in the ambient temperature (from −10 to 60 °C), which can cause a sevenfold decrease in the precision of the counter with a traditional calibration procedure.
