    2009-12-01

    This study reviews E85 dispensing infrastructure advances and issues and evaluates the geographic concentration of flexible fuel vehicles (FFVs), E85 stations, ethanol production facilities, and E85 suppliers. Costs, space, financial incentives, and barriers to adding E85 fueling equipment at existing stations are also assessed. This study found that E85 is increasingly available in the U.S. in half of the states; however, the other half have minimal or no E85 fueling options. Despite these gains, E85 is only available at 1% of U.S. gasoline stations. Ethanol production reached 9.5 billion gallons in 2008, but less than 1% is consumed as E85. FFVs have not reached a significant concentration in any county, metropolitan area, or state.

    This is a study on the optimized dispensing of the auto dispenser used for the purpose of reducing the exposure dose and accurate radiation dose of radioisotope with regard to the PET/CT practitioners. The research method was to find the optimized dispensing method through evaluating the results according to the syringe type, dispensing rate, and vial pressure and through the application of corrected values. As a result of this study, 9.38 mCi has been dispensed on average in the case of 5 ml syringe, and the reproducibility close to 10 mCi was shown at the dispense of 9.55 mCi in the case of 3 ml syringe. In the evaluation according to the dispensing rate, the quantity of radioisotope close to 10 mCi was dispensed at the rate of 5 mm/min when the measurement was carried out by increasing the rate by 5 mm/min units in the order of 5, 10, 15 and 20 mm/min . In the evaluation result according to the vial pressure before/after the use of Needle filter, it was measured to be 9.53 mCi before use and 9.84 mCi after use confirming that the dispensing after using Needle filter showed the optimal value. In addition, in the evaluation of radioactivity before/after the application of corrected values according to the increase in dispense frequency, it was measured 9.53 mCi before correction and 10.07 mCi after correction confirming that the value with correction applied was closer to the quantitative value. Thus, a good optimized method was confirmed to use a 3 ml syringe with dispensing rate of 5 mm/min, to use a Needle filter at dispensing, and to set the corrected value of [y = 0.097 × χ] according to the dispensing frequency of equipment.

    This is the final report for a grant-funded project to financially assist and otherwise provide support to projects that increase E85 infrastructure in Michigan at retail fueling locations. Over the two-year project timeframe, nine E85 and/or flex-fuel pumps were installed around the State of Michigan at locations currently lacking E85 infrastructure. A total of five stations installed the nine pumps, all providing cost share toward the project. By using cost sharing by station partners, the $200,000 provided by the Department of Energy facilitated a total project worth $746,332.85. This project was completed over a two-year timetable (eight quarters). The first quarter of the project focused on project outreach to station owners about the incentive on the installation and/or conversion of E85 compatible fueling equipment including fueling pumps, tanks, and all necessary electrical and plumbing connections. Utilizing Clean Energy Coalition (CEC) extensive knowledge of gasoline/ethanol infrastructure throughout Michigan, CEC strategically placed these pumps in locations to strengthen the broad availability of E85 in Michigan. During the first and second quarters, CEC staff approved projects for funding and secured contracts with station owners; the second through eighth quarters were spent working with fueling station owners to complete projects; the third through eighth quarters included time spent promoting projects; and beginning in the second quarter and running for the duration of the project was spent performing project reporting and evaluation to the US DOE. A total of 9 pumps were installed (four in Elkton, two in Sebewaing, one in East Lansing, one in Howell, and one in Whitmore Lake). At these combined station locations, a total of 192,445 gallons of E85, 10,786 gallons of E50, and 19,159 gallons of E30 were sold in all reporting quarters for 2011. Overall, the project has successfully displaced 162,611 gallons (2,663 barrels) of petroleum, and reduced

    A 5.0L V8 twin-turbocharged direct injection engine was designed, built, and tested for the purpose of assessing the fuel economy and performance in the F-Series pickup of the Dual Fuel engine concept and of an E85 optimized FFV engine. Additionally, production 3.5L gasoline turbocharged direct injection (GTDI) EcoBoost engines were converted to Dual Fuel capability and used to evaluate the cold start emissions and fuel system robustness of the Dual Fuel engine concept. Project objectives were: to develop a roadmap to demonstrate a minimized fuel economy penalty for an F-Series FFV truck with a highly boosted, high compression ratio spark ignition engine optimized to run with ethanol fuel blends up to E85; to reduce FTP 75 energy consumption by 15% - 20% compared to an equally powered vehicle with a current production gasoline engine; and to meet ULEV emissions, with a stretch target of ULEV II / Tier II Bin 4. All project objectives were met or exceeded.

    How demand for E85 might evolve in the future in response to changing economics and policies is an important subject to include in the National Energy Modeling System (NEMS). This report summarizes a study to develop an E85 choice model for NEMS. Using the most recent data from the states of Minnesota, North Dakota, and Iowa, this study estimates a logit model that represents E85 choice as a function of prices of E10 and E85, as well as fuel availability of E85 relative to gasoline. Using more recent data than previous studies allows a better estimation of non-fleet demand and indicates that the price elasticity of E85 choice appears to be higher than previously estimated. Based on the results of the econometric analysis, a model for projecting E85 demand at the regional level is specified. In testing, the model produced plausible predictions of US E85 demand to 2040.

    Anecdotal evidence suggests retail E85 prices may track retail gasoline prices rather than wholesale costs. This indicates E85 prices may be higher than they would be if priced on a cost basis hence limiting adoption by some price-sensitive consumers. Using publicly available and proprietary E85 and regular gasoline price data, we examine pricing behavior in the market for E85. Specifically, we assess the extent to which local retail competition in E85 markets decreases E85 retail prices. Results of econometric analysis suggest that higher levels of retail competition (measured in terms of station density) are associated with lower E85 prices at the pump. While more precise causal estimates may be produced from more comprehensive data, this study is the first to our knowledge that estimates the spatial competition dimension of E85 pricing behavior by firms. This technical report elaborates on a related presentation.

    Full Text Available Until 2011 there had been no full-time training course for dispensing optician diploma in Vietnam. Most of the practicing opticians with no qualification and formal training have learnt their skills through apprentice. In response to the demand of the industry Nguyen Tat Thanh University Vietnam has teamed up with Bradford College United Kingdom to develop a curriculum for a of formal 2-year full-time training for dispensing optician. The curriculum is applied for 4 semesters and graduate gets called Intermediate Professional Diploma level included 4 semesters. In VN after high school students can obtain different many levels of study such as Intermediate Professional Diploma College Bachelor Master and PhD. The 1st semester is basis of Intermediate Professional Diploma level. The 2nd semester is the study of refractive error and primary care each for 4 weeks 100 hours in theory and primary eye care 4 weeks for theory 100 hours. Also in this semester the learners have practiced clinical rotation at the Ophthalmic Hospital Ophthalmic Service in General Hospital for 10 weeks. The 3rd semester is specialized of dispensing Optician included Lenses frame contact lenses and laboratory for optician. In the 4th semester the training concentrates in the management of the eyeglasses shop and practicing in making spectacles for customers are in the 4th semester. The 1st intake of the course was opened started in 2011 and had 30 students graduated in 2013. This paper describes the experience of developing the curriculum in the context of a developing country where the industry is still under regulated and less developed. The first program optician that privileged on primary eye care will be satisfied for community WHO 2020 1 optometrist for 50.000 people and 10 ophthalmologists for 1.000.000 people. Some characteristics of first course students have been noted. The result of this curriculum will be evaluated in the coming time.

    Communities will rely on open points of dispensing (PODs) for mass dispensing of medical countermeasures following a bioterrorism attack or a pandemic. US Cities Readiness Initiative (CRI) open POD preparedness is assessed using the Technical Assistance Review (TAR) but focuses on oral prophylaxis dispensing; mass vaccination readiness is not well measured. Non-CRI preparedness had not been studied. In 2013 an online questionnaire was sent to all 456 CRIs and a random sample of 500 non-CRIs to measure open POD preparedness and exercise participation. Hierarchical linear regression was used to describe factors associated with higher POD preparedness and exercise participation scores. In total, 257 subjects participated, for a 41% response rate. Almost all open PODs have existing written plans and/or a layout for each site (93.4%, n=240, and 87.0%, n=220). Only half (46.7%, n=120) have an alternative dispensing modality in place, and even fewer (42.6%, n=104) report having adequate staffing. Determinants of open POD preparedness were perceived preparedness, participation in more POD exercises, and more closed POD coverage. Most jurisdictions conducted a full-scale exercise and a staff notification drill (83.7%, n=215 for both). Fewer than half (40.5%, n=104) have conducted a vaccination clinic exercise. Determinants of increased POD exercises were perceived preparedness, years of work experience, community type (nontribal), and larger population. Because successful open POD deployment is critical, jurisdictions need to plan for mass vaccination, use of alternative dispensing modalities, and recruitment strategies to increase POD staffing.

    To date, little is known on applicability of different types of pharmaceutical dosage forms in an automated high-speed multi-dose dispensing process. The purpose of the present study was to identify and further investigate various process-induced and/or product-related limitations associated with multi-dose dispensing process. The rates of product defects and dose dispensing errors in automated multi-dose dispensing were retrospectively investigated during a 6-months follow-up period. The study was based on the analysis of process data of totally nine automated high-speed multi-dose dispensing systems. Special attention was paid to the dependence of multi-dose dispensing errors/product defects and pharmaceutical tablet properties (such as shape, dimensions, weight, scored lines, coatings, etc.) to profile the most suitable forms of tablets for automated dose dispensing systems. The relationship between the risk of errors in dose dispensing and tablet characteristics were visualized by creating a principal component analysis (PCA) model for the outcome of dispensed tablets. The two most common process-induced failures identified in the multi-dose dispensing are predisposal of tablet defects and unexpected product transitions in the medication cassette (dose dispensing error). The tablet defects are product-dependent failures, while the tablet transitions are dependent on automated multi-dose dispensing systems used. The occurrence of tablet defects is approximately twice as common as tablet transitions. Optimal tablet preparation for the high-speed multi-dose dispensing would be a round-shaped, relatively small/middle-sized, film-coated tablet without any scored line. Commercial tablet products can be profiled and classified based on their suitability to a high-speed multi-dose dispensing process.

    Protec Fuel Management project objectives are to help design, build, provide, promote and supply biofuels for the greater energy independence, national security and domestic economic growth through job creations, infrastructure projects and supply chain business stimulants. Protec Fuel has teamed up with station owners to convert 5 existing retail fueling stations to include E85 fuel to service existing large number of fleet FFVs and general public FFVs. The stations are located in high flex fuel vehicle locations in the state of TX. Under the project name, “Job Creation and Petroleum Independence with E85 in Texas,” Protec Fuel identified and successfully opened stations strategically located to maximize e85 fueling success for fleets and public. Protec Fuel and industry affiliates and FFV manufacturers are excited about these stations and the opportunities as they will help reduce emissions, increase jobs, economic stimulus benefits, energy independence and petroleum displacement.

    Epinephrine is life-saving in the treatment of anaphylaxis. A limited number of fixed-dose epinephrine formulations are available for out-of-hospital treatment of this disorder. To examine dispensing patterns for epinephrine formulations over 4 consecutive years in a population of 279,638 infants, children, and adolescents (from birth up to but not including the 17th birthday). We used the Drug Programs Information Network, an administrative claims database for prescriptions dispensed in ambulatory care settings, developed from real-time computer links with retail pharmacies in the province of Manitoba, Canada. We studied the specific epinephrine formulation dispensed and the precise age of the infant or child at the time it was dispensed. Epinephrine formulations were dispensed for 1.2% of the pediatric population (3,340 children). Boys comprised 59.5% of the recipients. Of all epinephrine formulations, 38.6% were dispensed as EpiPen Jr (0.15 mg), and 57.4% were dispensed as EpiPen (0.3 mg). EpiPen Jr was dispensed for patients ranging in age from 2 months to 16 years, 10 months, inclusive. EpiPen was dispensed for patients ranging in age from 1 year, 8 months to 16 years, 11 months, inclusive. During the 4 years studied, a subgroup of children transitioned from EpiPen Jr to EpiPen auto-injectors at a mean age of 6 years, 6 months +/- 2 years, 8 months (range 1 year, 10 months to 16 years, 11 months). Both EpiPen Jr and EpiPen auto-injectors were dispensed over almost the entire age range of the pediatric population. Physicians should consider a child's age more carefully when prescribing these auto-injectors. Additional concentrations of epinephrine are needed in these fixed-dose formulations.

    This paper presents results for dispensing living cells using a pneumatic dispensing system to verify the feasibility of using this system to fabricate biomaterials. Living cells (i.e., mouse 3T3-J2 fibroblast) were dispensed with different dispensing pressures in order to evaluate the effect of dispensing process on cell viability and proliferation. Based on the results of a live-dead assay, more than 80% of cell viability has been confirmed which was reasonably similar to that in the control group. Furthermore, measurement of cell metabolic activity after dispensing confirmed that the dispensed cell proliferated at a rate comparable to that of the control group. These results demonstrate that the pneumatic dispensing system is a promising tool for fabrication of biomaterials.

    : Risks of abuse, misuse and diversion of opioids are of concern. Obtaining opioid prescriptions from multiple prescribers, known as opioid shopping, is a way in which opioids may be abused and diverted. Previous studies relied on counting the number of prescribers or number of pharmacies a subject goes to in a year to define shopping behaviour, but did not distinguish successive prescribers from concomitant prescribers. : The aim of the study was to assess the frequency of opioid overlapping prescriptions from different prescribers, compare it with diuretics and benzodiazepines, and provide a definition of shopping behaviour that differentiates opioids from diuretics, avoiding the inappropriate flagging of individuals with legitimate use of opioids. : Population-based cohort study using the IMS LRx database. This database covers 65% of all retail prescriptions in the US and includes mail service and specialty pharmacy provider prescriptions independent of the method of payment. : Ambulatory. : Subjects with at least one dispensing for any type of opioid in 2008. Similar cohorts were created for subjects exposed to benzodiazepines or diuretics. Analyses were performed separately for naïve subjects and those with prior use. : Frequency of overlapping prescriptions defined as at least 1 day of overlapping dispensing of prescriptions written by two or more different prescribers at any time during an 18-month period. : A total of 25 161 024 subjects exposed to opioids were included, of whom 13.1% exhibited at least one episode of overlapping prescriptions during 18 months of follow-up. Almost 10% of subjects exposed to benzodiazepines and 13.8% of subjects exposed to diuretics exhibited a similar behaviour. Having overlapping prescriptions dispensed by three or more pharmacies differentiates opioids from the other medication classes. Using that criterion, the overall risk of shopping behaviour was 0.18% in subjects exposed to opioids, 0.10% in subjects exposed to

    ) tailpipe emission rates for E85- versus gasoline have been inconsistent. To date, this is the most comprehensive evaluation of available and new data. The large range of inter-vehicle variability illustrates why prior studies based on small sample sizes led to apparently contradictory findings. E85 leads to significant reductions in tailpipe nitrogen oxides (NO x ) and carbon monoxide (CO) emission rates compared to gasoline, indicating a potential benefit for ozone air quality management in NO x limited areas. The comparison of FFV tailpipe emissions between E85 and gasoline is sensitive to power demand and driving cycles.

    The Preliminary Assessment of Spatial Competition in the Market for E85 presentation and supplementary report from the U.S. Department of Energy’s National Renewable Energy Laboratory examine how the spacing of E85 fueling stations impacts E85 retail pricing. The analysis finds an inverse correlation between station density and E85 prices, with local competition putting downward pressure on E85 prices. A gas station with E85 whose nearest competitor is within a 0.5 mile radius is associated with a lower E85 price per gallon than an otherwise identical station with E85 whose nearest competitor is farther away. The analysis also finds a higher level of correlation between E85 and both E10 and wholesale gasoline prices than with ethanol costs. This indicates that E85 may, in fact, be priced with respect to its substitute fuel, and not based on the cost of its inputs. These findings help identify key trends and barriers in E85 markets and highlight data gaps that, if addressed, could help enable competitive E85 markets. The analysis was released in February 2017 and uses national and Minnesota-specific price data.

    Vietnam, a developing country, has had comparatively good health and human survival at low cost. The economic reform changed the health care system, and private pharmacies during the last 5 years have taken over a majority of the drug distribution. Problems include weaknesses in drug regulation and reported increases in antibiotic resistance. This case study, a purposive sample of two private pharmacies in Hanoi, explored management, including dispensing, inventory and financing, using the concept of triangulation. Observations and interviews of customers were complemented by stock inventory and interviews of the pharmacy staff. Drugs were classified according to the ATC code and the essential drug list of Vietnam. Pretested protocols were used. In all 1833 encounters were studied during the 2 weeks, out of which 286 were children. Less than 1% of customers came with prescriptions and 94.9% decided by themselves which drugs to buy. Antibiotics represented 17%, of which 90% were broad spectrum. Ampicillin dominated, both in children and adults. Some 50% of the antibiotics were given for 2.5 days or less. Less than 50% of the drugs were essential drugs (ED) on dispensing and even less on inventory. Antibiotics and vitamins were the most commonly sold drugs and, overall, brand names dominated. Little if any drug information was observed. Antibiotics were said to represent the most profitable drugs, according to the pharmacy staff. More than 20% of all products were combination drugs, including irrational and popular products with antibiotics and corticosteroids and combinations of aspirin, phenacetin and caffeine. This study shows an unexpectedly high proportion of customers, being "Tu Lam Bac Sy" (their own doctors), deciding themselves which drugs to buy. Although the "Doi moi" renovation has led to much improved drug availability, at least in urban setting, our case study highlights major problems in need of urgent actions. In particular the prevailing practices

    Despite rising healthcare costs, generic drugs are less frequently dispensed in Japan compared with other developed countries. This study aimed to describe changes in dispensing of branded and generic drugs and to explore possible factors that promote the use of generic drugs. We conducted a retrospective cohort study using a Japanese medical and pharmacy claims database. All proton pump inhibitors (PPIs) and histamine H2-receptor antagonists (H2RAs) with indications for gastroesophageal reflux disease (GERD) described on Japanese labels were included. Patterns of dispensing branded and generic drugs for the treatment of GERD between 2006 and 2011 were analyzed. Multivariate logistic regression was applied to investigate factors associated with receiving generic drugs. The study cohort included 14,590 patients (male: 50.2%, mean age: 43.1 years). Branded drugs for GERD were still frequently dispensed despite an increase in the share of generic drugs. Only 4.3% of patients who initially received branded drugs switched to generic drugs. The percentage of patients who received only generic drugs increased over time (6.5% to 22.1%). The frequency of generic drug dispensing was the highest in the setting where both prescription and dispensing were implemented in clinics (43.3%), while the lowest in the setting where both prescription and dispensing were implemented in hospitals (11.5%). Factors associated with receiving generic drugs included year of dispensing (adjusted OR 2.22, 95% CI 1.94 to 2.55 for 2009-11 v 2006-8), prescription and dispensing setting (OR 1.81, 95% CI 1.44 to 2.26 for prescription in hospitals and dispensing in community pharmacies; OR 2.21, 95% CI 1.80 to 2.72 for prescription in clinics and dispensing in community pharmacies; and OR 4.55, 95% CI 3.68 to 5.62 for prescription and dispensing in clinics v prescription and dispensing in hospitals) and H2RAs (OR 1.64, 95% CI 1.49 to 1.81 compared to PPIs).

    The study aimed to describe the dispensing of benzodiazepines and benzodiazepine-related drugs (z-hypnotics) to pregnant women and to study the characteristics of these women and the extent of co-medication. A population-based cohort study was conducted based on the linkage of nationwide registries: the Medical Birth Registry of Norway and the Norwegian Prescription Database. The data covers dispensed drugs to women 3 months prior to, during and after pregnancy. The study population consisted of 345,703 singleton pregnancies during a period starting 1 April 2004 or later and ending before 1 January 2011. In 5,135 (1.5 %) of the pregnancies, the women were dispensed a benzodiazepine or z-hypnotic at least once. Of these, 68.5 % filled just one prescription for the duration of the pregnancy. Prevalence was lower in pregnancy than before and after pregnancy. The median total amount of benzodiazepines and/or z-hypnotics dispensed during pregnancy was 15 defined daily doses (DDDs), while the 25 % receiving the largest amounts got 40 DDDs or more. Five hundred eleven women, the 10 % that were prescribed the largest amounts during pregnancy, received a median amount of 220 DDDs. Women receiving these drugs were older, more often smokers, without a partner and suffering from chronic disease. Of the medicated pregnant women, 19.6 % and 19.3 % were also prescribed an opioid and antidepressant, respectively. The use of benzodiazepines and z-hypnotic drugs during pregnancy was not very prevalent in Norway. However, our findings imply that there is a substantial number of pregnancies where these drugs are dispensed often and/or in large quantities and where co-medication occurred.

    There are only 0.70 licensed physicians per 1000 people in India. Thus, pharmacies are a primary source of healthcare and patients often seek their services directly, especially in village settings. However, there is wide variability in a pharmacy employee's training, which contributes to inappropriate antibiotic dispensing and misuse. These practices increase the risk of antibiotic resistance and poor patient outcomes. This study seeks to better understand the factors that drive inappropriate antibiotic dispensing among pharmacy employees in India's village communities. We conducted a mixed-methods study of the antibiotic dispensing practices, including semistructured interviews and a pilot cross-sectional Knowledge, Attitudes and Practice survey. All data were transcribed, translated from Hindi into English, and coded for themes. Community pharmacies in villages in Haryana, India. We recruited 24 community pharmacy employees (all male) by convenience sampling. Participants have a range of characteristics regarding village location, monthly income, baseline antibiotic knowledge, formal education and licensure. 75% of pharmacy employees in our study were unlicensed practitioners, and the majority had very limited understanding of antibiotic resistance. Furthermore, only half could correctly define the term antibiotics. All reported that at times they dispensed antibiotics without a prescription. This practice was more common when treating patients who had limited access to a licensed physician because of economic or logistic reasons. Many pharmacy workers also felt pressure to provide shortened medication courses to poorer clientele, and often dispensed only 1 or 2 days' worth of antibiotics. Such patients rarely returned to the pharmacy for the complete course. This study highlights the need for short-term, intensive training programmes on antibiotic prescribing and resistance that can be disseminated to village pharmacies. Programme development should take into

    This short report evaluates the feasibility of using electronic vending machines for dispensing oral, fluid, rapid HIV self-testing kits in Los Angeles County. Feasibility criteria that needed to be addressed were defined as: (1) ability to find a manufacturer who would allow dispensing of HIV testing kits and could fit them to the dimensions of a vending machine, (2) ability to identify and address potential initial obstacles, trade-offs in choosing a machine location, and (3) ability to gain community approval for implementing this approach in a community setting. To address these issues, we contracted a vending machine company who could supply a customized, Internet-enabled machine that could dispense HIV kits and partnered with a local health center available to host the machine onsite and provide counseling to participants, if needed. Vending machines appear to be feasible technologies that can be used to distribute HIV testing kits.

    Full Text Available Background: Although emergency contraceptive pills are available over the counter, the quality of consultation, including key areas of contraceptive counseling and prevention of sexually transmitted infections (STI, has not been well documented. Objective: To evaluate actual pharmacist services while dispensing emergency contraception through a mystery shopper technique. Material and Methods: This cross-sectional study was conducted in 81 pharmacies situated in Delhi by 4 trained mystery shoppers posed as customers over a period of 6 months. Results: None of the pharmacists asked about the time lapsed since last unprotected sexual intercourse or last menstrual period before deciding the eligibility of the customer. The majority were unclear about side effects associated with emergency contraception (78.57% or with anticipated changes in menstrual flow (78.57%; 85.71% did not know whether subsequent unprotected intercourse would be protected. Only 15.71% counseled shoppers regarding risk of STI on asking leading questions and 88.5% did not provide any contraceptive advice. Conclusion: There is a huge gap in the technical knowledge and mindset of the pharmacists when it comes to checking for the eligibility of the client and providing advice regarding use of regular contraception and barrier for protection from STI, which needs to be addressed in order to realize the full benefit of making emergency contraceptive pills available over the counter.

    Full Text Available Medication dispensing is an important activity that can have major implications if done improperly. Dispensing must be done in the correct time interval, at the correct user, with the correct drug and dose. We propose a smart medication dispenser that can satisfy these needs and provide a mechanism for supervision. In order to ensure that the dispensing process is error free, the concept of a new smart medication container is used. A smart medication container is “smart” as it holds the medication dispensing parameters for the drugs it contains: dispensing time and date and name. Based on this information, the actual dispensing is done.

    Full Text Available The objective of the study was to evaluate the knowledge of pharmacists and check their conduct in relation to dispensing of drugs. This is a cross-sectional study performed in four municipalities from South and Southeast of Brazil, which are reference in health national scenario and concentrate 73.6% of national economic activity. Pharmacists who works in community pharmacies were invited to answer a questionnaire prepared by the authors of this study and validated. The main outcome measured was the pharmaceutical knowledge, rated according to the number of correct answers on that questionnaire prepared by the researchers, and professional conduct in relation to dispensing of drugs. The data collection occurred from September to December 2012 and the information obtained were tabulated in duplicate by two independent researchers for later analysis. 486 community pharmacies were visited but only 112 professionals participated in the study. Among the participants, 78.6% (n = 88 did not have adequate knowledge to perform the dispensing of drugs, despite this same number of pharmacists claiming to have participated in conferences and courses after graduation. The main sources of information on drugs used by participants have a low level of scientific evidence. The performance of non-employment related tasks reduces the time available for the care of medication users. In addition, the indiscriminate sale of antimicrobials and the sale of products other than health, mischaracterize the role of the pharmacist in the community pharmacy. There are gaps in the knowledge of professionals, limiting the satisfactory completion of dispensing of drugs. In addition, the excess of other duties and inadequate professional conduct compromise the promotion of the rational use of drugs.

  17. Population prevalence of high dose paracetamol in dispensed paracetamol/opioid prescription combinations: an observational study

    2012-01-01

    Background Paracetamol (acetaminophen) is generally considered a safe medication, but is associated with hepatotoxicity at doses above doses of 4.0 g/day, and even below this daily dose in certain populations. Methods The Nova Scotia Prescription Monitoring Program (NSPMP) in the Canadian province of Nova Scotia is a legislated organization that collects dispensing information on all out-of-hospital prescription controlled drugs dispensed for all Nova Scotia residents. The NSPMP provided data to track all paracetamol/opioids redeemed by adults in Nova Scotia, from July 1, 2005 to June 30, 2010. Trends in the number of adults dispensed these prescriptions and the numbers of prescriptions and tablets dispensed over this period were determined. The numbers and proportions of adults who filled prescriptions exceeding 4.0 g/day and 3.25 g/day were determined for the one-year period July 1, 2009 to June 30, 2010. Data were stratified by sex and age (paracetamol/opioid prescription was lower in each successive one-year period. From July 2009 to June 2010, one in 12 adults (n = 59,197) filled prescriptions for over 13 million paracetamol/opioid tablets. Six percent (n = 3,786) filled prescriptions that exceeded 4.0 g/day and 18.6% (n = 11,008) exceeded 3.25 g/day of paracetamol at least once. These findings exclude non-prescription paracetamol and paracetamol–only prescribed medications. Conclusions A substantial number of individuals who redeem prescriptions for paracetamol/opioid combinations may be at risk of paracetamol-related hepatotoxicity. Healthcare professionals must be vigilant when prescribing and dispensing these medications in order to reduce the associated risks. PMID:22709372

    In Tanzania, progress toward achieving the 2015 Millennium Development Goals for maternal and newborn health was slow. An intervention brought together community health workers, health facility staff, and accredited drug dispensing outlet (ADDO) dispensers to improve maternal and newborn health through a mechanism of collaboration and referral. This study explored barriers, successes, and promising approaches to increasing timely access to care by linking the three levels of health care provision. The study was conducted in the Kibaha district, where we applied qualitative approaches with in-depth interviews and focus group discussions. In-depth interview participants included retail drug shop dispensers (36), community health workers (45), and health facility staff members (15). We conducted one focus group discussion with district officials and four with mothers of newborns and children under 5 years old. Relationships among the three levels of care improved after the linkage intervention, especially for ADDO dispensers and health facility staff who previously had no formal communication pathway. The study participants perceptions of success included improved knowledge of case management and relationships among the three levels of care, more timely access to care, increased numbers of patients/customers, more meetings between community health workers and health facility staff, and a decrease in child and maternal mortality. Reported challenges included stock-outs of medicines at the health facility, participating ADDO dispensers who left to work in other regions, documentation of referrals, and lack of treatment available at health facilities on the weekend. The primary issue that threatens the sustainability of the intervention is that local council health management team members, who are responsible for facilitating the linkage, had not made any supervision visits and were therefore unaware of how the program was running. The study highlights the benefits of

    2014-01-01

    Automatic dispensing machines (ADMs) used in pharmacies concentrate and dispense large volumes of pharmaceuticals, including uncoated tablets that can shed dust. We evaluated 43 employees' exposures to pharmaceutical dust at three pharmacies where ADMs were used. We used an optical particle counter to identify tasks that generated pharmaceutical dust. We collected 72 inhalable dust air samples in or near the employees' breathing zones. In addition to gravimetric analysis, our contract laboratory used internal methods involving liquid chromatography to analyze these samples for active pharmaceutical ingredients (APIs) and/or lactose, an inactive filler in tablets. We had to choose samples for these additional analyses because many methods used different extraction solvents. We selected 57 samples for analysis of lactose. We used real-time particle monitoring results, observations, and information from employees on the dustiness of pharmaceuticals to select 28 samples (including 13 samples that were analyzed for lactose) for analysis of specific APIs. Pharmaceutical dust was generated during a variety of tasks like emptying and refilling of ADM canisters. Using compressed air to clean canisters and manual count machines produced the overall highest peak number concentrations (19,000-580,000 particles/L) of smallest particles (count median aerodynamic diameter ≤ 2 μm). Employees who refilled, cleaned, or repaired ADM canisters, or hand filled prescriptions were exposed to higher median air concentrations of lactose (5.0-12 μg/m(3)) than employees who did other jobs (0.04-1.3 μg/m(3)), such as administrative/office work, labeling/packaging, and verifying prescriptions. We detected 10 APIs in air, including lisinopril, a drug prescribed for high blood pressure, levothyroxine, a drug prescribed for hypothyroidism, and methotrexate, a hazardous drug prescribed for cancer and other disorders. Three air concentrations of lisinopril (1.8-2.7 μg/m(3)) exceeded the lower

    A potentially illuminating way of looking at gender differences in health and disease is to study differences in drug utilization. The aim of this study was to describe gender differences in dispensed analgesics (including nonsteroidal anti-inflammatory drugs [NSAIDs]) in Sweden during 2006-2015. The Swedish Board of Health and Welfare holds an open, Anatomical Therapeutic Chemical (ATC)-based statistical database containing aggregated data on all dispensed prescription drugs in Swedish pharmacies since 2006. The database is searchable according to sex, age (5-year intervals), and Swedish regions. Nationwide, whole-population information was retrieved for all ATC codes at the second level for individuals ≥20 years of age, focusing on sex-related differences. More in-depth analyses were made for analgesics, including NSAIDs. Descriptive statistics were used. Gender differences in drug prescription are pervasive in Sweden; the yearly prevalence in 2015 was higher in women for 72 out of 84 ATC groups (not adjusted for age). Analgesics, including NSAIDs, were more commonly used by women in all age groups. Gender differences were sustained over time (2006-2015) and were particularly striking for triptans. For both men and women, the yearly prevalence of opioids was stable during 2006-2015, whereas it increased for paracetamol and decreased for NSAIDs. The increase in paracetamol prescription was most noticeable for young females, and the decrease in NSAID prescription was largest in older patients (irrespective of sex). Gender differences in the use of analgesics probably mirror the higher prevalence of chronic pain in women.

The dispenser is a micro-electro-mechanical systems (MEMS) device fabricated in a bonded silicon wafer and a substrate, such as glass or silicon, using integrated circuit-like fabrication technology which is amenable to mass production. The dispensing is actuated by ultrasonic transducers that efficiently produce a pressure wave in capillaries that contain the chemicals. The 10-200 {micro}m diameter capillaries can be arranged to focus in one spot or may be arranged in a larger dense linear array (ca. 200 capillaries). The dispenser is analogous to some ink jet print heads for computer printers but the fluid is not heated, thus not damaging certain samples. Major applications are in biological sample handling and in analytical chemical procedures such as environmental sample analysis, medical lab analysis, or molecular biology chemistry experiments. 4 figs.

    Topical metered-dosing dispensers are designed for dosing accuracy and ease-of-use by the patients while protecting the packaged products from environmental exposure and contamination. The objective of this study was to evaluate the accuracy, precision, and residual of available topical metered-dosing dispensers with different types of topical cream for practical application. Triplicate samples of five different dispensers were tested. This test was completed using three types of commercial topical cream-bases of dissimilar Total Active Pharmaceutical Ingredient Load Percentages, Transdermal Penetration Percentages, and Specific Gravities. The dispensers were evaluated according to specified dose-uniformity criteria for a total dispensing capacity of 30 mL at 0.5 mL per dose for 60 doses. The study shows Topi-CLICK performed with the best precision and accuracy of dosing in comparison to the airless-pump type dispensers. While the dispensing was highly variable with airless pumps and may require calibration for each packaged product, remarkably the performance of Topi-CLICK was not affected by different types of cream-bases and does not require additional metering calibration.

    Full Text Available Background: In 2007, the South African government introduced the occupation-specific dispensation (OSD, a financial incentive strategy, to attract, motivate, and retain health professionals in the public sector. Implementation commenced with the nursing sector, but there have been unintended negative consequences. Objective: First, to examine implementation of the OSD for nurses using Hogwood and Gunn's framework that outlines ‘perfect implementation’ pre-conditions. Second, to highlight the conditions for the successful implementation of financial incentives. Methods: A qualitative case study design using a combination of a document review and in-depth interviews with 42 key informants. Results: The study found that there were several implementation weaknesses. Only a few of the pre-conditions were met for OSD policy implementation. The information systems required for successful policy implementation, such as the public sector human resource data base and the South African Nursing Council register of specialised nurses were incomplete and inaccurate, thus undermining the process. Insufficient attention was paid to time and resources, dependency relationships, task specification, and communication and coordination. Conclusion: The implementation of financial incentives requires careful planning and management in order to avoid loss of morale and staff grievances.

    The use of biofuels for internal combustion engines has several well published advantages. The biofuels, made from biological sources such as corn or sugar cane, are renewable resources that reduce the dependence on fossil fuels. Fuels from agricultural sources can therefore reduce a countries energy dependency on other nations. Biofuels also have been shown to reduce CO2 emissions into the atmosphere compared to traditional fossil based fuels. Because of these benefits several countries have set targets for the use of biofuels, especially ethanol, in their transportation fuels. Small percentages of ethanol are common place in gasoline but are typically limited to 5 to 8% by volume. Greater benefits are possible from higher concentrations and some countries such as the US and Sweden have encouraged the production of vehicles capable of operating on E85 (85% denatured ethanol and 15% gasoline). E85 capable vehicles are normally equipped to run the higher levels of ethanol by employing modified fuel delivery systems that can withstand the highly corrosive nature of the alcohol. These vehicles are not however equipped to take full advantage of ethanol's properties during the combustion process. Ethanol has a much higher blend research octane number than gasoline. This allows the use of higher engine compression ratios and spark advance which result in more efficient engine operation. Ethanol's latent heat of vaporization is also much higher that gasoline. This higher heat of vaporization cools the engine intake charge which also allows the engine compression ratio to be increased even further. An engine that is optimized for operation on high concentrations of ethanol therefore will have compression ratios that are too high to avoid spark knock (pre-ignition) if run on gasoline or a gasoline/ethanol blend that has a low percentage alcohol. An engine was developed during this project to leverage the improved evaporative cooling and high octane of E85 to

    Full Text Available Dispensing error is not uncommon in the medication proccess. Otomatisation of outpatient pharmacy services decrease the incidence of dispensing error, as well as improving the efficiency of picking, packing and labeling process. Since August 2014 an automated dispensing machine was installed in outpatient pharmascy Bethesda Hospital Yogyakarta, integrated with electronic prescribing and hospital information system. The objective of the study was to evaluate the impact of automated dispensing machine on the dispensing error at outpatient pharmacy Services using before and after study method. The procentage of drugs deliver by automated dispensing machine at the third and sixth month of implementation was 46% and 59%. Failure mode and effeect analysis of dispensing process done before the implementation, and the integration with electronic prescription and hospital information system, as well as the development of smart pack is the key of successed. The average of medications picked after the implementation of automated dispensing machine was (37,915.33 ± 3,160.12, higher than before implementation (36,812.67 ± 2,890.81, but not significant. The average of dispensing error after implementation (15,67 ± 6,28 was reduced significantly (p<0,05 than before (50.33 ± 34.47. The most frequent type of dispensing error were wrong quantity dispensed, wrong drug dispensed and wrong strength dispensed. The implementation of automated dispensing machine significantly reduce the incidence of dispensing error. Further investigaation needed to know the incidence of dispesning error cause by the machine and manual and factors that influenced.

    Two randomised controlled trials have found a higher risk of rhabdomyolysis in users of 80 mg versus 20 mg simvastatin, but there is very limited information about the risk associated with other doses. We undertook a nested case-control study, using routinely collected national health and drug dispensing data, to estimate the relative and absolute risks of rhabdomyolysis resulting in hospital admission or death according to simvastatin dose. The underlying study cohort comprised all patients (n=313,552) who initiated a new episode of simvastatin use in New Zealand between 1 May 2005 and 31 December 2009. Cases (n=29) were patients with a diagnosis of rhabdomyolysis after cohort entry, confirmed by hospital discharge letter or death records. Ten controls, matched by year of birth and sex, were randomly selected from the study cohort using risk set sampling. Current users of 40 mg simvastatin daily were about five times as likely to develop rhabdomyolysis as those taking 20mg; the adjusted odds ratio was 5.3 (95% CI 1.9-15.0). The absolute excess risk of rhabdomyolysis associated with the use of 40 mg versus 20mg was about 10 per 100,000 person-years; the crude incidence rates were 11.5 (95% CI 7.1-17.5) and 2.1 (95% CI 0.7-4.8) per 100,000 person-years respectively. These findings provide reassurance that the absolute risk of rhabdomyolysis in a general population of simvastatin users is very low. Nonetheless, they also raise questions about the optimal simvastatin regimen to maximise cardiovascular benefits and minimise the risk of serious muscle injury. Copyright © 2014 The Authors.

    Eichenberg, Dennis J.

    2003-01-01

    An apparatus that is extremely effective in dispensing a wide range of droplets has been developed. This droplet dispenser is unique in that it utilizes a droplet bias voltage, as well as an ionization pulse, to release a droplet. Apparatuses that deploy individual droplets have been used in many applications, including, notably, study of combustion of liquid fuels. Experiments on isolated droplets are useful in that they enable the study of droplet phenomena under well-controlled and simplified conditions. In this apparatus, a syringe dispenses a known value of liquid, which emerges from, and hangs onto, the outer end of a flat-tipped, stainless steel needle. Somewhat below the needle tip and droplet is a ring electrode. A bias high voltage, followed by a high-voltage pulse, is applied so as to attract the droplet sufficiently to pull it off the needle. The voltages are such that the droplet and needle are negatively charged and the ring electrode is positively charged.

    Many interventions have been implemented to improve hand hygiene compliance, each with varying effects and monetary costs. Although some previous studies have addressed the issue of conspicuousness, we found only 1 study that considered improving hand hygiene by using flashing lights. Our attention theory-based hypothesis tested whether a simple red light flashing at 2-3 Hz affixed to the alcohol gel dispensers, within the main hospital entrance, would increase hand hygiene compliance over the baseline rate. Baseline and intervention observations were completed over five 60-minute periods (Monday-Friday) from 7:30 to 8:30 AM using a covert observation method. Baseline hand hygiene compliance was 12.4%. Our intervention increased compliance to 23.5% during cold weather and 27.1% during warm weather. Overall, our pooled compliance rate increased to 25.3% (P < .0001). A simple, inexpensive flashing red light affixed to alcohol gel dispensers was sufficiently salient to approximately double overall hand hygiene compliance within the main hospital entrance. We hypothesize that our intervention drew attention to the dispensers, which then reminded employees and visitors alike to wash their hands. Compliance was worse during cold days, presumably related to more individuals wearing gloves. Copyright © 2014 Association for Professionals in Infection Control and Epidemiology, Inc.

    2012-01-01

    Full Text Available There have been a number of substantive technical changes that can be described as revolutionary process and evolutionary process. One of these approaches is the use of nanotechnology in the two-stage pyrolysis of petroleum residues of the heavy distillates separated from the Arabian crude oil. Two-stage catalytic pyrolysis technique proved to be an excellent method for the production of unsaturated hydrocarbons (which easily can be converted to alcohol, by addition of H2O, for the production of E-85, i.e., clean fuel regardless the type of feed stocks used. Basically, the catalysts are arranged into three large groups; amorphous and crystalline alumino-silicates, alkaline or alkaline earth alumino compounds, and different metal oxides on different catalyst carriers such as Zeolites. The high yield of ethylene (30–40% brought by different catalysts at temperatures of 700–750°C appear to justify the intensive research work in this field.

    To measure the thickness at which primary schoolchildren apply sunscreen on school day mornings and to compare it with the thickness (2.00 mg/cm(2)) at which sunscreen is tested during product development, as well as to investigate how application thickness was influenced by age of the child (school grades 1-7) and by dispenser type (500-mL pump, 125-mL squeeze bottle, or 50-mL roll-on). A crossover quasiexperimental study design comparing 3 sunscreen dispenser types. Children aged 5 to 12 years from public primary schools (grades 1-7) in Queensland, Australia. Children (n=87) and their parents randomly recruited from the enrollment lists of 7 primary schools. Each child provided up to 3 observations (n=258). Children applied sunscreen during 3 consecutive school weeks (Monday through Friday) for the first application of the day using a different dispenser each week. Thickness of sunscreen application (in milligrams per square centimeter). The dispensers were weighed before and after use to calculate the weight of sunscreen applied. This was divided by the coverage area of application (in square centimeters), which was calculated by multiplying the children's body surface area by the percentage of the body covered with sunscreen. Children applied their sunscreen at a median thickness of 0.48 mg/cm(2). Children applied significantly more sunscreen when using the pump (0.75 mg/cm(2)) and the squeeze bottle (0.57 mg/cm(2)) compared with the roll-on (0.22 mg/cm(2)) (Pdispensers seem to facilitate thicker application than others.

    Objectives To compare prevalence and types of dispensing errors and pharmacists’ labelling enhancements, for prescriptions transmitted electronically versus paper prescriptions. Design Naturalistic stepped wedge study. Setting 15 English community pharmacies. Intervention Electronic transmission of prescriptions between prescriber and pharmacy. Main outcome measures Prevalence of labelling errors, content errors and labelling enhancements (beneficial additions to the instructions), as identified by researchers visiting each pharmacy. Results Overall, we identified labelling errors in 5.4% of 16 357 dispensed items, and content errors in 1.4%; enhancements were made for 13.6%. Pharmacists also edited the label for a further 21.9% of electronically transmitted items. Electronically transmitted prescriptions had a higher prevalence of labelling errors (7.4% of 3733 items) than other prescriptions (4.8% of 12 624); OR 1.46 (95% CI 1.21 to 1.76). There was no difference for content errors or enhancements. The increase in labelling errors was mainly accounted for by errors (mainly at one pharmacy) involving omission of the indication, where specified by the prescriber, from the label. A sensitivity analysis in which these cases (n=158) were not considered errors revealed no remaining difference between prescription types. Conclusions We identified a higher prevalence of labelling errors for items transmitted electronically, but this was predominantly accounted for by local practice in a single pharmacy, independent of prescription type. Community pharmacists made labelling enhancements to about one in seven dispensed items, whether electronically transmitted or not. Community pharmacists, prescribers, professional bodies and software providers should work together to agree how items should be dispensed and labelled to best reap the benefits of electronically transmitted prescriptions. Community pharmacists need to ensure their computer systems are promptly updated

    A lyophilized spore dispenser is provided which produces a finely divided, monoparticulate cloud of bacterial spores. The spores are contained within a tightly sealed chamber, and a turbulator orifice connected to an air supply source provides a jet of air which stirs up the spores and causes the spores to be suspended in eddy currents within the chamber. This air jet also produces a positive pressure within the chamber which forces the spores out of an injection orifice.

    A technical and economic assessment is being conducted of a hydrogen fuel dispensing station to develop an understanding of the infrastructure requirements for supplying hydrogen fuel for mobile applications. The study includes a process design of a conceptual small-scale, stand-alone, grassroots fuel dispensing facility (similar to the present-day gasoline stations) producing hydrogen by steam reforming of natural gas. Other hydrogen production processes (such as partial oxidation of hydrocarbons and water electrolysis) were reviewed to determine their suitability for manufacturing the hydrogen. The study includes an assessment of the environmental and other regulatory permitting requirements likely to be imposed on a hydrogen fuel dispensing station for transportation vehicles. The assessment concludes that a dispensing station designed to produce 0.75 million standard cubic feet of fuel grade (99.99%+ purity) hydrogen will meet the fuel needs of 300 light-duty vehicles per day. Preliminary economics place the total capital investment (in 1994 US dollars) for the dispensing station at $4.5 million and the annual operating costs at around $1 million. A discounted cash-flow analysis indicates that the fuel hydrogen product price (excluding taxes) to range between $1.37 to $2.31 per pound of hydrogen, depending upon the natural gas price, the plant financing scenario, and the rate of return on equity capital. A report on the assessment is due in June 1995. This paper presents a summary of the current status of the assessment.

    Treatment with antidepressants is often compromised by substantial nonadherence. To understand nonadherence, specific medication-related behaviors and beliefs have been studied, but less is known about broader and temporally stable personality "traits." Furthermore, adherence has often been assessed by a single method. Hence, we investigated associations between the Big Five personality traits and adherence assessed by self-report, electronic drug use monitoring, and dispensing data. Using the Big Five Inventory, we assessed the personality traits "openness," "conscientiousness," "extraversion," "agreeableness," and "neuroticism" of patients treated with antidepressants who were invited through community pharmacies. Self-reported adherence was assessed with the Medication Adherence Rating Scale (score >24), electronic monitoring with medication event monitoring system (MEMS) devices (therapy days missed ≤ 10% and self-reported adherence (odds ratio, 3.63; 95% confidence interval, 1.34-9.86 and odds ratio, 2.97; 95% confidence interval, 1.09-8.08; P ≤ 0.05). No relationships were found between personality traits and adherence assessed through electronic drug use monitoring or dispensing data. We therefore conclude that adherence to antidepressant therapy seems to be largely unrelated to personality traits.

    Recent studies evaluating bulk soap in public restroom soap dispensers have demonstrated up to 25% of open refillable bulk-soap dispensers were contaminated with ~ 6 log(10)(CFU ml(-1)) heterotrophic bacteria. In this study, plastic counter-mounted, plastic wall-mounted and stainless steel wall-mounted dispensers were analyzed for suspended and biofilm bacteria using total cell and viable plate counts. Independent of dispenser type or construction material, the bulk soap was contaminated with 4-7 log(10)(CFU ml(-1)) bacteria, while 4-6 log(10)(CFU cm(-2)) biofilm bacteria were isolated from the inside surfaces of the dispensers (n = 6). Dispenser remediation studies, including a 10 min soak with 5000 mg l(-1) sodium hypochlorite, were then conducted to determine the efficacy of cleaning and disinfectant procedures against established biofilms. The testing showed that contamination of the bulk soap returned to pre-test levels within 7-14 days. These results demonstrate biofilm is present in contaminated bulk-soap dispensers and remediation studies to clean and sanitize the dispensers are temporary.

    To characterize the medicine dispensing services in the primary health care network in Brazil and in its different regions, aiming to promote the access and rational use of medicines. This is a cross-sectional, quantitative study with data obtained from the Pesquisa Nacional sobre Acesso, Utilização e Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), 2015. Observation visits were carried out in 1,175 dispensing units, and interviews were held with 1,139 professionals responsible for the dispensation of medicines in the dispensing units and 495 municipal coordinators of pharmaceutical services. More than half (53%) of the units presented a space smaller than 10 m2 for dispensing of medicines; 23.8% had bars or barriers between users and dispenser; 41.7% had computerized system; and 23.7% had counters for individual care. Among those responsible for dispensation, 87.4% said they always or repeatedly inform users how to use the medicines, and 18.1% reported developing some type of clinical activity. Isolated pharmacies presented a more developed physical and personal structure than those belonging to health units, but we found no significant differences regarding the information provided and the development of clinical activities. There are major differences in the organization models of dispensation between cities, with regional differences regarding the physical structure and professionals involved. The centralization of medicine dispensing in pharmacies separated from the health services is associated with better structural and professional conditions, as in the dispensing units of the South, Southeast, and Midwest regions. However, the development of dispensation as health service does not prevail in any pharmacy or region of the Country yet.

RESULTS More than half (53% of the units presented a space smaller than 10 m2 for dispensing of medicines; 23.8% had bars or barriers between users and dispenser; 41.7% had computerized system; and 23.7% had counters for individual care. Among those responsible for dispensation, 87.4% said they always or repeatedly inform users how to use the medicines, and 18.1% reported developing some type of clinical activity. Isolated pharmacies presented a more developed physical and personal structure than those belonging to health units, but we found no significant differences regarding the information provided and the development of clinical activities. CONCLUSIONS There are major differences in the organization models of dispensation between cities, with regional differences regarding the physical structure and professionals involved. The centralization of medicine dispensing in pharmacies separated from the health services is associated with better structural and professional conditions, as in the dispensing units of the South, Southeast, and Midwest regions. However, the development of dispensation as health service does not prevail in any pharmacy or region of the Country yet.

    To evaluate the effect of a digital dispenser's acoustic alarm function on adherence to ethinylestradiol (EE) 20 μg/drospirenone 3 mg in a flexible extended regimen (EE/drospirenoneFlex) among women in five European countries (France, Germany, Italy, Spain, UK) seeking oral contraception. Randomized, parallel-group open-label study. Women aged 18-35 years received EE/drospirenoneFlex administered in a regimen with cycle lengths of their choice with the aid of a digital pill dispenser over 1 year. In group A (N=250), the dispenser's acoustic alarm was activated (ie, acoustic alarm + visual reminder). In group B (N=249), the acoustic alarm was deactivated (ie, visual reminder only). In addition, the women recorded pill intake daily in diary cards. The primary efficacy variable was the mean delay of daily pill release after the dispenser reminded the woman to take a pill (reference time). Secondary efficacy variables included number of missed pills, contraceptive efficacy, bleeding pattern, tolerability, and user satisfaction. Dispenser data showed a mean (standard deviation [SD]) daily delay in pill release of 88 (126) minutes in group A vs 178 (140) minutes in group B (Pdispenser's activated acoustic alarm improved adherence with daily tablet intake of EE/drospirenoneFlex, reducing missed pills. EE/drospirenoneFlex provided effective contraception and a good tolerability profile.

    Forty anesthesia providers were evaluated with and without hand sanitizer dispensers present on the anesthesia machine. Having a dispenser increased the frequency of hand hygiene only from 0.5 to 0.8 events per hour (P = .01). Other concomitant interventions are needed to further increase hand hygiene frequency among anesthesia providers.

    Opioids are frequently prescribed for moderate to severe pain. A side effect of opioid usage is the inhibition of gastrointestinal (GI) motility, known as opioid-induced bowel dysfunction (OBD). OBD is typically treated prophylactically with laxatives and/or acid suppressants. The present study describes the prevalence of outpatient opioid dispensing, opioid patient demographics, and concomitant dispensing of opioids and GI medications in the Quebec Public Prescription Drug Insurance Plan in 2005. Using a retrospective cohort design, opioid dispensings were identified using claims and reimbursement data. Laxative and acid suppressant dispensings were also identified. Concurrent use was defined as having at least one 'GI medication-exposed day' overlapping an 'opioid-exposed day'. More than 11% of the drug plan population was dispensed an opioid in 2005, and dispensings increased with age. Approximately two-thirds of patients who received an opioid were given codeine. Approximately one-third of opioid patients were concomitantly dispensed a GI medication, yet only 2% were dispensed a laxative. Although the GI side effects of opioids are well known, these side effects appear to increase with age and duration of opioid use. Opioid-related side effects, particularly OBD, should be effectively managed so as not to lead to the cessation of opioid therapy.

    Mass dispensing of medical countermeasures has been proven to be an effective and crucial means to contain the outbreak of highly infectious disease. The large influx of individuals to the point-of dispensing (POD) centers to receive vaccinations or prophylactic treatment, however, raises the potential risk of serious intra-facility cross-infections. To mitigate the effect, a thorough understanding of how disease propagates during the dispensing under different transmission parameters versus POD design and operational factors is necessary. In this study, we employ a large-scale simulation/optimization decision support system, RealOpt, to analyze the propagation of highly infectious disease within dispensing sites. The simulation results are validated and benchmarked by a mathematical model based on ordinary differential equations. Pros and cons of using analytical versus simulation tools are discussed. We further perform sensitivity analysis on the dynamics of intra-POD disease propagation, and explore feasible mitigation strategies for effective mass dispensing.

    While clinician attitudes towards electronic prescribing (e-prescribing) systems have been widely studied, little is known about the perspectives of patients, despite being the primary beneficiaries of these systems. The objective of this study is to explore and compare patient and clinician attitudes towards an integrated e-prescribing and dispensing system, in order to guide improvements in system implementation, service delivery and enhancements to system functionality. A cross-sectional survey was developed and administered to patients and multidisciplinary clinicians at a multisite Australian metropolitan teaching hospital network in all areas where e-prescribing was fully implemented. Participants' views on perceived impact and valued features of the e-prescribing system were elucidated. Overall, 783 participants (400 patients and 383 clinicians) completed the survey. Although 98% of clinicians were aware of the transition to e-prescriptions, only 36% of patients were aware prior to the study. Over 80% of patients and clinicians perceived improvements in prescribing and dispensing safety and clinician workflow; 90% of patients were comfortable with information privacy associated with e-prescriptions; and 86% of patients preferred e-prescriptions to handwritten prescriptions. Although over 80% of patients valued features that improved access to information and medication safety, clinicians were more discerning about valued system features. The majority of patients and clinicians reported a positive impact of e-prescribing on safety and efficiency. Both groups valued safe and effective use of medicines, although differences existed in the importance placed on key system features. A greater focus on patient engagement and communication is needed to optimise the delivery of patient-centred care.

    To examine the impact of contact lens application in non-contact lens wearers prior to spectacle dispensing. Ninety-one eligible subjects with no previous contact lens experience were randomly assigned into either a test group (52 subjects) or control group (39 subjects). The former group was offered contact lenses before spectacle dispensing. The latter group proceeded to spectacle dispensing in the normal way without being offered contact lenses. The response to the offer of contact lenses, fit success, the impact on the spectacle dispensing process and the longer term purchase of contact lenses were measured and compared for the test and control groups. Of the test group, 46 (88%) agreed to try contact lenses. All subjects were suitable for contact lenses after a slit lamp examination and lenses were successfully fitted to 45 of the 46 subjects (98%). The test group reported a superior subjective spectacle dispensing experience and spent 267+/-143 pounds (mean+/-standard deviation) on their spectacle frames and lenses, 32% more than the control group (202+/-128 pounds). At 3 months post dispensing, 17 test patients (33% of original cohort) had purchased contact lenses compared with five control subjects (13%) (p=0.001). The opportunity to try contact lenses prior to spectacle dispensing was well received by subjects who generally reported a very positive experience. In particular, contact lenses assisted in seeing frame detail and suitability for wear. One third of subjects proceeded to purchase contact lenses. We recommend that practitioners consider offering contact lenses to all suitable patients who are proceeding to spectacle dispensing to optimise the dispensing process and to provide an opportunity to try contact lenses.

This study compared the antibiotics dispensing practice between ADDOs and part II shops, or duka la dawa baridi (DLDBs, in Tanzania.Methodology: This was a cross-sectional study that was conducted in ADDOs and DLDBs. A simulated client method for data collection was used, and a total of 85 ADDOs, located in Mvomero, Kilombero, and Morogoro rural districts, were compared with 60 DLDBs located in Kibaha district. The research assistants posed as simulated clients and requested to buy antibiotics from ADDOs and DLDBs after presenting a case scenario or disease condition. Among the diseases presented were those requiring antibiotics and those usually managed only by oral rehydration salt or analgesics. The simulated clients wanted to know the antibiotics that were available at the shop. The posed questions set a convincing ground to the dispenser either to dispense the antibiotic directly, request a prescription, or refer the patient to a health facility. Proportions were used to summarize categorical variables between ADDOs and DLDBs, and the chi-square test was used to test for statistical difference between the two drug-outlet types in terms of antibiotic-dispensing practice.Results: As many as 40% of trained ADDO dispensers no longer worked at the ADDO shops, so some of the shops employed untrained staff. A larger proportion of ADDOs than DLDBs dispensed antibiotics without prescriptions (P = 0.004. The overall results indicate that there was no difference between the two types of shops in terms of adhering to regulations for dispensing antibiotics. However, in some circumstances, eg

The average dispensing time (ADT, percentage of drugs actually dispensed (PDAD, percentage of drugs adequately labeled (PDAL and patient′s knowledge on correct dosage (PKCD were compared in these selected teaching hospitals (TH, general hospitals (GHs and district hospitals (DHs in Galle. ADT in DH (1.16 min and GH (1.07 min were high when compared with ADT in TH (0.81 min. PDAD was 100% in DH, 97.79% in GH and lowest in TH (94.64%. PDAL was highest (22.66% in TH, 17.57% in GH and lowest in DH (1.57%. PKCD was 100% in GH and lowest in DH (0% and only 50% in TH in Galle district. We noted that there was a significant difference in ADT in all three categories (P < 0.05. We noted that dispensers spend only a short dispensing time and showed a tendency for dispensing errors. We found that PDAL was very low in all hospitals but PDAD was significantly high. Even though the ADT was high in DH, PKCD was 0% due to negligence in dispensing practices. We also noted a 100% PKCD only in GH due to the practice of a well-prepared correct labeling system in GH. We noticed that these patients were provided drugs with inadequate labeling and that patients had only a poor knowledge about the drug administration schedule. We conclude that there was a low dispenser-patient ratio in all three hospitals and that there was a need for an implementation plan for proper dispensing techniques by introducing a well-prepared drug labeling system in a printed format.

    Objectives The aim of this study was to explore whether recording in primary care of a previously recorded hospital diagnosis was associated with increased patient utilisation of recommended medications. Design Registry-based prospective cohort study. Setting and participants 19 072 patients with a hospital discharge diagnosis of transient ischaemic attack (TIA), stroke or acute coronary syndrome from hospitals in Stockholm County 2010–2013 were included in the study. Main outcome measure The outcome of the study was medication dispensation as a marker of adherence to recommended medications. Adherence was defined as having had at least two filled prescriptions in the third year following hospital discharge. Results Recording a diagnosis was associated with higher utilisation of all recommended medications with the exception of antihypertensives in patients with TIA. The differences between the groups with and without a recorded diagnosis remained after adjusting for age, sex, index year and visits to private practitioners. Dispensation of antithrombotics was high overall, 80%–90% in patients without a recorded diagnosis and 90%–94% for those with a diagnosis. Women with recorded ischaemic stroke/TIA/acute coronary syndrome were dispensed more statins (56%–71%) than those with no recorded diagnosis (46%–59%). Similarly, 68%–83% of men with a recorded diagnosis were dispensed statins (57%–77% in men with no recorded diagnosis). The rate of diagnosis recording spanned from 15% to 47% and was especially low in TIA (men 15%, women 16%). Conclusion Recording a diagnosis of TIA/stroke or acute coronary syndrome in primary care was found to be associated with higher dispensation of recommended secondary preventive medications. Further study is necessary in order to determine the mechanisms underlying our results and to establish the utility of our findings. PMID:28939569

Investigating dispensing errors is important for identifying the factors involved and developing strategies to reduce their occurrence. Objectives: To review published studies exploring the incidence and types of dispensing errors in hospital pharmacies and factors contributing to these errors. Methods: Electronic databases including PubMed, Scopus, Ovid, and Web of Science were searched for articles published between January 2000 and January 2015. Inclusion criteria were: studies published in English, and studies investigating type, incidence and factors contributing to dispensing errors in hospital pharmacies. One researcher searched for all relevant published articles, screened all titles and abstracts, and obtained complete articles. A second researcher assessed the titles, abstracts, and complete articles to verify the reliability of the selected articles. Key findings: Fifteen studies met the inclusion criteria all of which were conducted in just four countries. Reviewing incident reports and direct observation were the main methods used to investigate dispensing errors. Dispensing error rates varied between countries (0.015%–33.5% depending on the dispensing system, research method, and classification of dispensing error types. The most frequent dispensing errors reported were dispensing the wrong medicine, dispensing the wrong drug strength, and dispensing the wrong dosage form. The most common factors associated with dispensing errors were: high workload, low staffing, mix-up of look-alike/sound-alike drugs, lack of knowledge/experience, distractions/interruptions, and communication problems within the dispensary team. Conclusion: Studies relating to dispensing errors in hospital pharmacies are few in number and have been conducted in

Pharmacist have a crucial role in promoting good pharmacy practice. To assess the dispensing practice of the community pharmacists in the Turkish Republic of Northern Cyprus (TRNC) regarding RDU and to evaluate the quality of dispensing. Setting Community pharmacies in TRNC. Method The study consists of two parts: a face to face interview and a simulated patient visit to these pharmacies. Rationality indicators (average dispensing time, stock availability and adequate labelling), presence of the pharmacist on the premises, dispenser characteristics, prescription checking, and the provided patient information. The majority of the prescriptions (73.3%) were dispensed by the pharmacists. None of the pharmacy employees had pharmacy based training. Eighty nine percent of the pharmacists believed that their employees could very well dispense drugs on their own. The declared average dispensing time for a prescription of a single drug was 233 s while the measured one was 149 s. Few dispensers in reality warned the patient about potential interactions. The difference between the average dispensing scores of the pharmacists and the non-pharmacist dispensers was not significant. The dispensing practice in the community pharmacies in the Turkish part of Cyprus seems inadequate in terms of GPP.

    The timing and duration of approaches by male peachtree borer Synanthedon exitiosa Say (Lepidoptera: Sesiidae) to commercial pheromone dispensers placed singly or at high density in peach orchards was determined by using field-deployed video cameras and digital video recorders. Cameras were trained on one dispenser, and one standard lure was placed in a peach orchard, and on 12 dispensers in a separate orchard where dispensers for mating disruption had been placed at 371 per hectare. Male moth approaches were video recorded at the peak of peachtree borer annual flight, from 13 to 18 August 2009. The mean approach timing (h:min:sec±SD) during the study period was 11:33:12 ± 00:46:43, 11:43:52 ± 00:45:58, and 11:41:21 ± 00:45:54 AM with the single dispenser, high-density dispensers, and lure, respectively. Day-to-day variability in approach timings suggested that there were no biologically significant differences among treatments. The frequency distribution of approach durations varied among treatments, as the high-density dispensers had mostly short approaches, while the distribution of approaches to the single dispenser and lure was wider. The median (interquartile range) approach duration was 3 (2-4), 1 (1-2), and 4 (2-6) seconds with the single dispenser, high-density dispensers, and lure, respectively. The relative rank of median approach durations was constant throughout the period, indicating differences among treatments. This study showed that the presence of pheromone dispensers for mating disruption did not cause an advancement of peachtree borer diel rhythm of response. Shorter approaches to dispensers placed at high density than singly suggest that dispenser retentiveness is not constant with peachtree borer, which may bias estimates of disruption activity as a function of dispenser density.

    This study investigates the potential association between montelukast use and psychiatric adverse events by monitoring changes in antidepressant medication dispensing rates before and after initiating montelukast. The primary study group of montelukast initiators was identified using the Wolters Kluwer's SOURCE Lx® pharmacy claims database (WK). This group included 232,159 patients ≤45 years old who had at least two montelukast prescriptions from 2003 to 2007. Comparison groups comprised of 264,704 fluticasone initiators and 89,635 long-acting β-agonist corticosteroid (LABA/ICS) initiators were also identified. Antidepressant medication dispensing rates in these three groups were determined using WK, and changes in rates before and after the first asthma controller medication prescription date were evaluated using interrupted time-series analysis (ITS). ITS was performed separately for four age categories, with a focus on youth (12-17 years) and young adult (18-24 years). For patients 18-24 years old, antidepressant medication dispensing rates increased significantly after initiating montelukast [1.93% (1.55-2.32%, p montelukast. However, similar increases were observed in the fluticasone and LABA/ICS comparison groups. The results of this study cannot support a specific association between initiation of montelukast treatment and an increase in psychiatric adverse effects.

    Full Text Available Obesity is defined as the excess adipose tissue in the body. Drugs responsible for inhibiting the appetite are called anorectics or appetite suppressants. Sibutramine, fenproporex and amfepramone belongs to this class, and are capable of causing physical or psychological dependence. The aim of this study was to evaluate the frequency of prescriptions for appetite suppressants in community pharmacies at Cruz Alta, State of Rio Grande do Sul, Brazil. The sales of fenproporex, amfepramone and sibutramine in the months of September, October and November 2010 and April, May and June 2011 were compared. It was observed that the most commonly dispensed anorectic in the three community pharmacies analyzed was sibutramine. In the months of September, October and November 2010, consumption was higher, with sibutramine achieving 40.3% of overall sales, amfepramone 21% and, finally, fenproporex, 7.9%. The consumption of appetite suppressants was more prevalent in females, who represented 82% of total. The results suggested the existence of high consumption of anorectics, possibly related to the current concern with aesthetic standards, which emphasizes the importance of strict control over the marketing of these substances.

    The medicinal use of cannabis is a growing phenomenon in the U.S. predicated on the success of overcoming specific spatial challenges and establishing particular human-environment relationships. This article takes a medical geographic "snapshot" of an urban site in Washington State where qualifying chronically ill and debilitated patients are delivered locally produced botanical cannabis for medical use. Using interview, survey, and observation, this medical geographic research project collected information on the social space of the particular delivery site and tracked the production cost, reach, and health value of a 32-ounce batch of strain-specific medical cannabis named "Plum" dispensed over a four-day period. A convenience sample of 37 qualifying patients delivered this batch of cannabis botanical medicine was recruited and prospectively studied with survey instruments. Results provide insight into patients' self-rated health, human-plant relationships, and travel-to-clinic distances. An overall systematic geographic understanding of the medical cannabis delivery system gives a grounded understanding of the lengths that patients and care providers go, despite multiple hurdles, to receive and deliver treatment with botanical cannabis that relieves diverse symptoms and improves health-related quality-of-life.

    Although developments in liquid dispensers have made the use of 1536-well plates for high-throughput screening (HTS) standard, there is still a gap in dispenser technology for performing matrix experiments with several components. Experiments such as those performed during assay development and enzymological studies are therefore still performed by manual pipetting in lower-density plates. We have evaluated a new dispenser, the Certus liquid dispenser (Gyger Fluidics GmbH, Switzerland), that is capable of flexible dispensing in 1536-well format, with a dead volume of less than 200 µL. Taking advantage of the precision of the dispenser for volumes down to 50 nL, we have created concentration gradients on plates by dispensing different volumes of reagent and then backfilling with buffer. Using this method and the flexibility of the dispenser software, we have performed several multidimensional experiments varying two to three components, including an assay development for an HTS, a mode of inhibition study, and a cofactor optimization, in which we determined 32 KM values. Overall, the flexibility of the plate layout for multiple components, the accuracy to dispense volumes ranging 2 log orders, and minimal reagent usage enable this dispenser for complex biochemical experiments.

    The aims of this study were to investigate how elderly people handle single-use eye drop dispensers (unit-dose pipettes) and to compare the performance with conventional eye drop bottles. In this open-label study, the handling of unit-dose pipettes and conventional eye drop bottles was compared in 41 elderly people who had little or no prior regular use of eye drop dispensers. The participants tested both types of dispenser once, and the following 7 variables were studied: ease/difficulty of opening the dispenser; influence of the size for handling of the dispenser; influence of the shape for handling of the dispenser; observation of the contents in the dispenser; the feeling of the dispenser in the hand; ease/difficulty of drop instillation on the eye from the dispenser; and overall performance of the eye drop dispenser. The dispensers contained isotonic saline, and a visual analog scale was used for assessment of each of the above variables. The mean age of the participants was 73 years. A statistically significant difference in favor of the unit-dose pipettes was found with respect to observation of the contents in the dispenser, ease of administration, and the overall performance. Women regarded the unit-dose pipettes generally better than the bottles, but such a difference was not seen in men. The study participants managed the unit-dose pipettes at least as well as the conventional eye drop bottles. If anything, the unit-dose pipettes appeared to be easier to use.

    New agricultural techniques are attempting to reduce the application of synthesized pesticides and replace them with new environmentally friendly methods such as mass trapping, mating disruption, or chemosterilization techniques. All these methods are based on the release of a lure for insect attraction or confusion. The success of the chosen method depends on the quality of the attractant emission from the dispenser. Currently, used dispensers with a polymeric matrix and new dispensers with mesoporous inorganic materials were evaluated to obtain more efficient emission kinetics. In this study, the selected pest was the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) and the lure used was trimedlure (TML). The dispensers were validated by means of a field study comparing insect catches with attractant release values. As a result, we have demonstrated that mesoporous dispensers have a clearly longer lifetime than the polymeric plug. Furthermore, the attractant release rate is less dependent on temperature in mesoporous than in polymeric dispensers.

    2005-06-01

    To determine the frequency and types of dispensing errors identified both at the final check stage and outside of a UK hospital pharmacy, to explore the reasons why they occurred, and to make recommendations for their prevention. A definition of a dispensing error and a classification system were developed. To study the frequency and types of errors, pharmacy staff recorded details of all errors identified at the final check stage during a two-week period; all errors identified outside of the department and reported during a one-year period were also recorded. During a separate six-week period, pharmacy staff making dispensing errors identified at the final check stage were interviewed to explore the causes; the findings were analysed using a model of human error. Percentage of dispensed items for which one or more dispensing errors were identified at the final check stage; percentage for which an error was reported outside of the pharmacy department; the active failures, error producing conditions and latent conditions that result in dispensing errors occurring. One or more dispensing errors were identified at the final check stage in 2.1% of 4849 dispensed items, and outside of the pharmacy department in 0.02% of 194,584 items. The majority of those identified at the final check stage involved slips in picking products, or mistakes in making assumptions about the products concerned. Factors contributing to the errors included labelling and storage of containers in the dispensary, interruptions and distractions, a culture where errors are seen as being inevitable, and reliance on others to identify and rectify errors. Dispensing errors occur in about 2% of all dispensed items. About 1 in 100 of these is missed by the final check. The impact on dispensing errors of developments such as automated dispensing systems should be evaluated.

  12. Measurement and analysis of thermal photoemission from a dispenser cathode

    Full Text Available Photocathodes for free electron lasers (FELs are required to produce nano-Coulomb pulses in picosecond time scales with demonstrable reliability, lifetime, and efficiency. Dispenser cathodes, traditionally a rugged and long-lived thermionic source, are under investigation to determine their utility as a photocathode and have shown promise. The present study describes theoretical models under development to analyze experimental data from dispenser cathodes and to create predictive time-dependent models to predict their performance as an FEL source. Here, a steady-state model of a dispenser cathode with partial coverage of a low work function coating and surface nonuniformity is developed. Quantitative agreement is found for experimental data, especially with regard to temperature, field, laser intensity, and quantum efficiency versus laser wavelength dependence. In particular, for long wavelength incident lasers of sufficient intensity, the majority of the absorbed energy heats the electron gas and background lattice, and photoemission from the heated electron distribution constitutes the emitted current.

This study aimed to assess the percentage of pharmacies that dispense antibiotics without a medical prescription in the Kingdom of Jordan and identify and highlight the extent and seriousness of such practices among Jordanian pharmacies. Methods: A prospective study was performed, and five different clinical scenarios were simulated at pharmacies investigated including sore throat, otitis media, acute sinusitis, diarrhea, and urinary tract infection in childbearing-aged women. Three levels of demand were used to convince the pharmacists to sell an antibiotic. Results: A total of 202 total pharmacies in Jordan were visited in the present study. The majority of pharmacies (74.3% dispensed antibiotics without prescription with three different levels of demand. The percentage of pharmacies dispensing antibiotics without a prescription for the sore throat scenario was 97.6%, followed by urinary tract infection (83.3%, diarrhea (83%, and otitis media (68.4%. The lowest percentage of antibiotic dispensing was for the acute sinusitis simulation at 48.5%. Among the pharmacies that dispensed antibiotics, the pharmacists provided an explanation as the number of times per day the drug should be taken in 95.3% of the cases, explained the duration of treatment in 25.7%, and inquired about allergies prior to the sale of the antibiotic in only 17.3%. Only 52 pharmacies (25.7% refused to dispense any kind of antibiotics, the majority (61.5% of this refusal response came from acute sinusitis cases, while the minority (2.4% came from the sore throat cases. Conclusion: The results of this study demonstrate that antibiotics continue to be dispensed

    The dispensable genome of a species, consisting of the dispensable sequences present only in a subset of individuals, is believed to play important roles in phenotypic variation and genome evolution. However, construction of the dispensable genome is costly and labor-intensive at present, and so the influence of the dispensable genome in genetic and functional genomic studies has not been fully explored. We construct the dispensable genome of rice through a metagenome-like de novo assembly strategy based on low-coverage (1-3×) sequencing data of 1483 cultivated rice (Oryza sativa L.) accessions. Thousands of protein-coding genes are successfully assembled, including most of the known agronomically important genes absent from the Nipponbare rice reference genome. We develop an integration approach based on alignment and linkage disequilibrium, which is able to assign genomic positions relative to the reference genome for more than 78.2 % of the dispensable sequences. We carry out association mapping studies for rice grain width and 840 metabolic traits using 0.46 million polymorphisms between the dispensable sequences of different rice accessions. About 23.5 % of metabolic traits have more significant association signals with polymorphisms from dispensable sequences than with SNPs from the reference genome, and 41.6 % of trait-associated SNPs have concordant genomic locations with associated dispensable sequences. Our results suggest the feasibility of building a species' dispensable genome using low-coverage population sequencing data. The constructed sequences will be helpful for understanding the rice dispensable genome and are complementary to the reference genome for identifying candidate genes associated with phenotypic variation.

    To assess medicine dispensing practices in private pharmacies in Dar-es-Salaam, Tanzania and recommend interventions to improve practice. A cross-sectional survey and observational study of dispensing practices among 70 pharmacies in metropolitan Dar-es-Salaam, Tanzania. There were 1479 dispensing encounters recorded across the 70 pharmacies. This translated to 1573 medicines dispensed. Of the medicines dispensed, 16% were anti-infectives; 45% of the dispensed medicines were requested by the client, 32% were recommended by the dispenser and only 23% were on prescriptions. The main reasons for pharmacy consultations were coughs (62%), general pain (62%) and 'flu and colds. Malaria constituted 21% of the private pharmacy visits. Of the cough encounters, 30% received antibiotics. In addition, oral antibiotics were given to 81% of the clients with diarrhoea and to 95% of those with eye and ear problems. Of the 628 clients who requested specific medicines without a prescription, only 29% were asked questions on why the medicines were required. Of the clients who bought antibiotics, 20% bought incomplete doses. In total, 1180 clients were interviewed. Of these, 35% could not repeat the instructions given to them by the dispenser. Of the 70 dispensers who gave dosage instructions, only 20% gave them according to guidelines. In Tanzania, an overwhelming proportion of medicines sold in pharmacies are dispensed without a prescription. The majority of medicines dispensed without a prescription are either requested by the client or recommended by the dispenser. When dispensing medicines, dispensers seldom give dosage instructions; when they do, the instructions are often not consistent with guidelines. A high proportion of clients seeking management of coughs and colds or for diarrhoea from private pharmacies receive antibiotics. Interventions that build the capacity of dispensers, improve the rational use of antibiotics and the management of diarrhoea in private pharmacies in

    Dissolvable microneedle (DMN) patches are novel dosage forms for the percutaneous delivery of vaccines. DMN are routinely fabricated by dispensing liquid formulations into microneedle-shaped moulds. The liquid formulation within the mould is then dried to create dissolvable vaccine-loaded microneedles. The precision of the dispensing process is critical to the control of formulation volume loaded into each dissolvable microneedle structure. The dispensing process employed must maintain vaccine integrity. Wetting of mould surfaces by the dispensed formulation is also an important consideration for the fabrication of sharp-tipped DMN. Sharp-tipped DMN are essential for ease of percutaneous administration. In this paper, we demonstrate the ability of a piezoelectric dispensing system to dispense picolitre formulation volumes into PDMS moulds enabling the fabrication of bilayer DMN. The influence of formulation components (trehalose and polyvinyl alcohol (PVA) content) and piezoelectric actuation parameters (voltage, frequency and back pressure) on drop formation is described. The biological integrity of a seasonal influenza vaccine following dispensing was investigated and maintained voltage settings of 30 V but undermined at higher settings, 50 and 80 V. The results demonstrate the capability of piezoelectric dispensing technology to precisely fabricate bilayer DMN. They also highlight the importance of identifying formulation and actuation parameters to ensure controlled droplet formulation and vaccine stabilisation. Copyright © 2015 Elsevier B.V.

  19. Gakkel Ridge at 85°E/85°N: Seismicity and Structure of an Ultraslow Spreading Centre

    2014-05-01

    Ultraslow spreading ridges are divergent plate boundaries, which spread apart with less than 20 mm/yr. Their appearance is very rugged, with steep rift flanks, numerous normal faults and discontinuous volcanic activity at discrete volcanic centres - drastically different from ridges which spread faster. Due to the inaccessible area where these ridges are found, much less is know about lithospheric structure than at faster spreading ridges. Gakkel Ridge spans between Greenland and Siberia, crossing through the Arctic Ocean. There, a perennial ice cover inhibits seismic surveys. At 85°E/85°N where the spreading rate is only about 10.2 mm/yr, a volcanic spreading centre is located. It was spectacularly active in 1999, spawning over 250 teleseismically registered earthquakes with body wave magnitudes up to 5.2 and lasting 9 months. At this site, volcanic cones and fresh lava were captured by seafloor imagery in 2007. Making use of the ice cover, three arrays of four seismometers each were deployed in 2007 on ice floes, drifting 16 days over the area and recording more than 300 local events. Due to the drift of the ice floes, the location of the arrays changed with time, resulting in sufficient ray coverage suitable for a local earthquake tomography. We present here the results of this tomography, the first ever done at an ultraslow spreading centre. We compiled a 1D local velocity model from confidently located hypocentres. While incorporating the varying 3D bathymetry and the water layer, we used 124 microearthquakes which had been recorded by at least two arrays for generating a local 3D earthquake tomographic model. At spreading rates below 20 mm/yr it has been proposed that conductive heat loss should increase, leading to a thinner crust. Yet, our results infer a deep Moho at about 7 km beneath seafloor and hypocentres as deep as 16 km (bsf.) which implies an exceptionally thick crust and cold lithosphere. Theoretical thermal models for the axial lithospheric

    It has been suggested that children that are exposed to a stressful environment at home have an increased susceptibility for air pollution-related asthma. The aim here was to investigate the association between air pollution exposure and asthma, and effect modification by mental health and by socio-economic status (as markers of a stressful environment). All individuals under 18 years of age in four Swedish counties during 2007 to 2010 (1.2 million people) were included. The outcome was defined as dispensing at least two asthma medications during follow up. We linked data on NO₂ from an empirical land use regression to data from national registers on outcome and potential confounders. Data was analyzed with logistic regression. There was an odds ratio (OR) of 1.02 (95% Confidence Interval (CI: 1.01-1.03) for asthma associated with a 10 µg·m -3 increase in NO₂. The association only seemed to be present in areas where NO₂ was higher than 15 µg·m -3 with an OR of 1.09 (95% CI: 1.07-1.12), and the association seemed stronger in children with parents with a high education, OR = 1.05 (95% CI: 1.02-1.09) and OR = 1.04 (95% CI: 1.01-1.07) in children to mothers and father with a high education, respectively. The association did not seem to depend on medication history of psychiatric disorders. There was weak evidence for the association between air pollution and asthma to be stronger in neighborhoods with higher education levels. In conclusion, air pollution was associated with dispensed asthma medications, especially in areas with comparatively higher levels of air pollution, and in children to parents with high education. We did not observe support for our hypothesis that stressors linked to socio-economy or mental health problems would increase susceptibility to the effects of air pollution on the development of asthma.

  3. Relative accuracy and availability of an Irish National Database of dispensed medication as a source of medication history information: observational study and retrospective record analysis.

    WHAT IS KNOWN AND OBJECTIVE: The medication reconciliation process begins by identifying which medicines a patient used before presentation to hospital. This is time-consuming, labour intensive and may involve interruption of clinicians. We sought to identify the availability and accuracy of data held in a national dispensing database, relative to other sources of medication history information. METHODS: For patients admitted to two acute hospitals in Ireland, a Gold Standard Pre-Admission Medication List (GSPAML) was identified and corroborated with the patient or carer. The GSPAML was compared for accuracy and availability to PAMLs from other sources, including the Health Service Executive Primary Care Reimbursement Scheme (HSE-PCRS) dispensing database. RESULTS: Some 1111 medication were assessed for 97 patients, who were median age 74 years (range 18-92 years), median four co-morbidities (range 1-9), used median 10 medications (range 3-25) and half (52%) were male. The HSE-PCRS PAML was the most accurate source compared to lists provided by the general practitioner, community pharmacist or cited in previous hospital documentation: the list agreed for 74% of the medications the patients actually used, representing complete agreement for all medications in 17% of patients. It was equally contemporaneous to other sources, but was less reliable for male than female patients, those using increasing numbers of medications and those using one or more item that was not reimbursable by the HSE. WHAT IS NEW AND CONCLUSION: The HSE-PCRS database is a relatively accurate, available and contemporaneous source of medication history information and could support acute hospital medication reconciliation.

    Neurobiological models of obesity postulate that obese individuals have difficulty regulating food intake partly because they attribute excessive salience to stimuli signaling food availability. Typically, human studies that investigate the relationship between brain responses to food-related stimuli and obesity present food cues without subsequent delivery of food. However, in order to identify the brain correlates of cue reactivity, we must record brain responses to food-related cues signaling food availability. Therefore, we have developed a dispensing apparatus for use in a cued-food delivery task in which event-related potentials (ERPs) to food-related images predicting food delivery and images not predicting food delivery can be recorded. Here, we describe a method where:•The experimental apparatus dispenses an edible item (i.e., a chocolate candy) which may or may not be eaten, or a non-edible control item (e.g., a plastic bead).•Deposit boxes are available to store uneaten candies and the non-edible control items.•The dispensing mechanism is capable of recording the exact timestamp when each delivery event occurs (e.g., release from the dispenser, arrival in the receptacle, storage in the deposit box).

    Bulk-soap-refillable dispensers are prone to extrinsic bacterial contamination, and recent studies demonstrated that approximately one in four dispensers in public restrooms are contaminated. The purpose of this study was to quantify bacterial hand contamination and transfer after use of contaminated soap under controlled laboratory and in-use conditions in a community setting. Under laboratory conditions using liquid soap experimentally contaminated with 7.51 log(10) CFU/ml of Serratia marcescens, an average of 5.28 log(10) CFU remained on each hand after washing, and 2.23 log(10) CFU was transferred to an agar surface. In an elementary-school-based field study, Gram-negative bacteria on the hands of students and staff increased by 1.42 log(10) CFU per hand (26-fold) after washing with soap from contaminated bulk-soap-refillable dispensers. In contrast, washing with soap from dispensers with sealed refills significantly reduced bacteria on hands by 0.30 log(10) CFU per hand (2-fold). Additionally, the mean number of Gram-negative bacteria transferred to surfaces after washing with soap from dispensers with sealed-soap refills (0.06 log(10) CFU) was significantly lower than the mean number after washing with contaminated bulk-soap-refillable dispensers (0.74 log(10) CFU; P soap (P soap from bulk-soap-refillable dispensers can increase the number of opportunistic pathogens on the hands and may play a role in the transmission of bacteria in public settings.

  8. Dispensing processes impact apparent biological activity as determined by computational and statistical analyses.

    Full Text Available Dispensing and dilution processes may profoundly influence estimates of biological activity of compounds. Published data show Ephrin type-B receptor 4 IC50 values obtained via tip-based serial dilution and dispensing versus acoustic dispensing with direct dilution differ by orders of magnitude with no correlation or ranking of datasets. We generated computational 3D pharmacophores based on data derived by both acoustic and tip-based transfer. The computed pharmacophores differ significantly depending upon dispensing and dilution methods. The acoustic dispensing-derived pharmacophore correctly identified active compounds in a subsequent test set where the tip-based method failed. Data from acoustic dispensing generates a pharmacophore containing two hydrophobic features, one hydrogen bond donor and one hydrogen bond acceptor. This is consistent with X-ray crystallography studies of ligand-protein interactions and automatically generated pharmacophores derived from this structural data. In contrast, the tip-based data suggest a pharmacophore with two hydrogen bond acceptors, one hydrogen bond donor and no hydrophobic features. This pharmacophore is inconsistent with the X-ray crystallographic studies and automatically generated pharmacophores. In short, traditional dispensing processes are another important source of error in high-throughput screening that impacts computational and statistical analyses. These findings have far-reaching implications in biological research.

    To study antidepressant drug dispensation in the Spanish region of Andalusia and in the Almeria Health Area (AHA) over the past decade, analyzing the variability, trends, and influential factors. We conducted an observational ecological study of antidepressant drug dispensation between 2000 and 2010 in Andalusia. Dispensation was measured as Defined Daily Dose (DDD) per 1,000 inhabitants per day. A multilevel analysis (STATA 11.1) was performed to determine the variability among the basic health zones (BHZs) (2004-2010) and influential factors. Between 2000 and 2010, the total dispensation of antidepressant drugs increased by more than 100 % in Andalusia and in the AHA. This increase was primarily caused by the greater dispensation of selective serotonin reuptake inhibitors (ATC-N06AB) and other antidepressants (ATC-N06AX). Multilevel analysis revealed a wide variability in the levels and trends of antidepressant dispensation among BHZs. Urbanicity and the percentage of immigrants in the BHZ were negatively associated with their dispensation, which was positively influenced by a higher proportion of women and over 65-year-olds in the population. The elevated dispensation of several groups of antidepressant drugs in this study population indicates the need for health policies to rationalize their use. Further research is required into the differences in antidepressant dispensations between immigrant and native populations and the implications for public health policies.

    Full Text Available UNLABELLED: This study aimed to comprehensively describe prevalence and temporal dispensing patterns for medications prescribed to children and adolescents in the United States. Participants were 1.6 million children (49% female under 18 years old enrolled in a nation-wide, employer-provided insurance plan. All medication claims from 1999-2006 were reviewed retrospectively. Drugs were assigned to 16 broad therapeutic categories. Effects of trend over time, seasonality, age and gender on overall and within category prevalence were examined. RESULTS: Mean monthly prevalence for dispensed medications was 23.5% (range 19.4-27.5, with highest rates in winter and lowest in July. The age group with the highest prevalence was one-year-old children. On average each month, 17.1% of all children were dispensed a single drug and 6.4% were dispensed two or more. Over time, prevalence for two or more drugs did not change, but the proportion of children dispensed a single drug decreased (slope -.02%, p= .001. Overall, boys had higher monthly rates than girls (average difference 0.9%, p= .002. However, differences by gender were greatest during middle childhood, especially for respiratory and central nervous system agents. Contraceptives accounted for a large proportion of dispensed medication to older teenage girls. Rates for the drugs with the highest prevalence in this study were moderately correlated (average Pearson r.66 with those from a previously published national survey. CONCLUSION: On average, nearly one quarter of a population of insured children in the United States was dispensed medication each month. This rate decreased somewhat over time, primarily because proportionally fewer children were dispensed a single medication. The rate for two or more drugs dispensed simultaneously remained steady.

    Artemisinin combination therapies are available in private outlets, but patient adherence might be compromised by poor advice from dispensers. In this cluster randomized trial in drug shops in Tanzania, 42 of 82 selected shops were randomized to receive text message reminders about what advice to provide when dispensing artemether-lumefantrine (AL). Eligible patients purchasing AL at shops in both arms were followed up at home and questioned about each dose taken. Dispensers were interviewed regarding knowledge of AL dispensing practices and receipt of the malaria-related text messages. We interviewed 904 patients and 110 dispensers from 77 shops. Although there was some improvement in dispenser knowledge, there was no difference between arms in adherence measured as completion of all doses (intervention 68.3%, control 69.8%, p [adjusted] = 0.6), or as completion of each dose at the correct time (intervention 33.1%, control 32.6%, p [adjusted] = 0.9). Further studies on the potential of text messages to improve adherence are needed. © The American Society of Tropical Medicine and Hygiene.

    Using a ternary sex pheromone blend [86:6:6 v:v:v (Z,Z)-3,13-octadecadienyl acetate: (E,Z)-2,13-octadecadienyl acetate: (Z,E)-3,13-octadecadienyl acetate], we tested the effect of dispenser type and trap design for capture of dogwood borer (DWB), Synanthedon scitula Harris (Lepidoptera: Sesiidae) in apple orchards in West Virginia, Virginia, and North Carolina. Wing-style sticky traps baited with polyethylene vial pheromone dispensers captured more male DWB over the first 2 months than traps baited with rubber septum pheromone dispensers. However, catches in vial-baited traps decreased considerably after the first 2 months, possibly due to the antagonistic effect of 3,5-di-tert-butyl-4-hydroxy acetophenone that diffused from the polyethylene vials. By contrast, traps baited with rubber septum dispensers captured DWB males for at least 6 months; over the last four months of the flight season, catches in traps baited with a rubber septum were greater than those in traps baited with a vial dispenser. Therefore, the rubber septum dispenser is recommended for season-long monitoring of DWB. A release-rate study, using laboratory and field-aged dispensers, demonstrated that desorption of DWB sex pheromone from polyethylene vial or rubber septum dispensers followed first order kinetics, with half-lives of 1.6 and 10.7 months, respectively. Several trap designs, including wing-and delta-style sticky traps, and white and green "bucket-style" traps, baited with rubber septum dispensers were compared in commercial apple orchards for catch of DWB. Bucket traps caught more moths when moth populations were high, because the sticky surfaces of the 1C and delta traps likely became saturated. However, among the commercially available traps tested, no particular design gave consistently higher catches. Further work is needed to explore capture mechanisms and maintenance needs of different trap types.

    2017-02-13

    In developing country like BANGLADESH, people depend more on pharmacies due to expediency, shorter waiting time, cost reduction, availability of credit and flexible opening hours. The aim of this study was to investigate medicines dispensing patterns of the pharmacies in RAJSHAHI, BANGLADESH and to identify and analyze contribution of drugsellers and quacks in irrational drug use. This cross-sectional study was conducted during January 2016 - April, 2016 in 75 randomly selected private pharmacies including both licensed and unlicensed pharmacies of covering LAKSHMIPUR area. During the whole study process, total 7944 clients visited the pharmacies under observation and 24,717 medicines were dispensed. 22.70% of all these drugs were sold without a prescription. Out of the 5610 items dispensed without prescription, 66.2% were dispensed on the request of clients themselves and 33.8% on the recommendation of a drug seller. Number of medicine in a prescription was highly variable ranging from 2 to 5 medicines per prescriptions (mean = 3.03). The average number of medicines dispensed from each of the pharmacies during the observation period was 392, varied pharmacy to pharmacy - ranging from 194 to 588. Lowest selling medicines were sedative and hypnotics and highest selling medicines were antimicrobials. The recommendation rate for antibiotics was highest for the quacks (26.48%) though the major amount of the antimicrobials (n = 3039, 65.83%) were dispensed on prescription. Macrolides, quinolones, metronidazoles and cephalosporins are most favourite drug of quacks, clients and pharmacists. Majority of medicines were dispensed irrationally without any prescription and over the counter dispensing of many low safety profile drugs was common. The results and discussion presented in this paper will be helpful to provide a baseline to redirect further studies in this area.

    Compliance in medicine dispensation has proven critical for dosage control, diagnosis, and treatment. We have designed, manufactured, and characterized a novel dynamically programmable e-pill dispensing system. Our system is initially programmed remotely through a cell phone. After programming, the system may be reconfigured in order to adapt pill dispensation to new conditions. In this paper we describe the mechanics, electronics, control, and communication protocols implemented. Our dyn-e-pill devices can be actuated for over 350 h with two pill retrievals per hour. We challenged the charging circuit and demonstrated that the system has a lifetime longer than 6 h with a 30 min charging cycle, while it lasts for 14 h of uninterrupted use with a full charge.

  18. State legal innovations to encourage naloxone dispensing.

    Science.gov (United States)

    Davis, Corey; Carr, Derek

    The opioid overdose epidemic continues to claim the lives of tens of thousands of Americans every year. Increased access to the opioid antagonist naloxone can reduce opioid-related morbidity and mortality. In this commentary, we describe several recent legal innovations designed to encourage pharmacists to ensure that naloxone is available when and where it is needed, and dispel some common misconceptions regarding potential legal risks associated with pharmacy naloxone dispensing. Data are drawn from state laws and regulations, as catalogued by the Westlaw database. States have rapidly modified law and policy to increase layperson access to naloxone. As of August 2016, 44 states permit naloxone to be prescribed for administration to a person with whom the prescriber does not have a prescriber-patient relationship. Forty-two states permit naloxone to be dispensed via a non-patient-specific mechanism such as a standing or protocol order, and 5 states permit some pharmacists to prescribe naloxone on their own authority. The liability risk associated with naloxone dispensing is no higher than any other medication, and may be lower than some. However, to encourage the prescription and dispensing of naloxone, 36 states provide additional protection from civil liability for pharmacy naloxone dispensing, and 32 states provide protection from potential criminal action. Naloxone access laws in 31 states explicitly provide that dispensing naloxone as permitted by law cannot be grounds for disciplinary action by the state board of pharmacy or similar entity. Pharmacists are key members of the health care team and are uniquely situated to reduce potential opioid overdose risk. Pharmacists should be aware of and utilize innovative state laws designed to increase access to naloxone. Copyright © 2017 American Pharmacists Association®. Published by Elsevier Inc.

    Evaluation of compound activity in vitro is crucial to drug discovery efforts and require that the compounds be accurately and reliably titrated and dispensed to the assay wells. The HP D300 dispenser uses inkjet technology to achieve small-volume dispensing that allows concentration-response testing using the direct dilution paradigm. Although inkjet technology has been long in existence, it is new to the field of screening and drug development. We have evaluated the D300 dispenser in a biochemical assay, a cell-based reporter gene assay, and a cytotoxicity assay. The software for this instrument is user friendly, and the compound-dispensing process is streamlined. However, a limitation is that this dispenser is currently applicable to only 96-well and 384-well plate formats and not to 1536-well high-density plates. Our results indicate that the D300 generates clean and reproducible results that correlate with those produced with more commonly used instruments such as the pin tool. We found that the instrument is useful and can improve the throughput of compound dispensing in 96-well and 384-well plates.

    In order to automate sample preparation processes, a precision pattern dispenser was designed to reproducibly dispense radioactive solutions at pre-defined positions. It is composed of an automatic liquid sample handling unit coupled to an XYZ table. Qualification tests were conducted to evaluate the performance of the instrument and to assess the compliance with the requirements, in particular trueness (< 2%) and repeatability (< 1%). The instrument allows preparing sources in different source holders and on air filters, in a fast and accurate way. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

  1. Process For Patterning Dispenser-Cathode Surfaces

    Garner, Charles E.; Deininger, William D.

    1989-01-01

    Several microfabrication techniques combined into process cutting slots 100 micrometer long and 1 to 5 micrometer wide into tungsten dispenser cathodes for traveling-wave tubes. Patterned photoresist serves as mask for etching underlying aluminum. Chemically-assisted ion-beam etching with chlorine removes exposed parts of aluminum layer. Etching with fluorine or chlorine trifluoride removes tungsten not masked by aluminum layer. Slots enable more-uniform low-work function coating dispensed to electron-emitting surface. Emission of electrons therefore becomes more uniform over cathode surface.

    We study the loading of sodium atoms into a magneto-optical trap from current-controlled sodium metal dispensers. Contrary to what was previously reported [V. Wippel, C. Binder, W. Huber, L. Windholz, M. Allegrini, F. Fuso, E. Arimondo, Eur. Phys. J. D 17 (2001) 285] we demonstrate a significantly higher number of trapped atoms that make Na dispensers a feasible source of atoms for cold-atom studies. The inherent rise in pressure that naturally arises from metal dispensers as they are heated to release atoms is partially controlled by placing the metal dispensers near the pumping port where an ion pump is connected. We also study the effects of placing the sodium dispensers at different distances from the main vacuum chamber where the atoms are trapped and the effectiveness of using a Zeeman slower to cool the atoms as they emerge from the dispensers. We observe trapping of up to 1.9 × 10 8 atoms, which is significantly higher by almost three orders of magnitude than previously reported experiments.

    The aim of this article is to design and pilot a protocol for the dispensing of medications service. Using the requirements proposed in the Ministry of Health Pharmaceutical Care Consensus, a literature search was made applying qualitative consensus techniques. An observational, cross-sectional study was conducted from March to June 2009. A total of 53 community pharmacies from 24 Spanish counties. Patients who requested one or more particular medications with or without medical prescription for their own use or for someone in their care. The personalised medication information (IPM), the problems associated with the medications (PRM), and the negative results associated with the medication (RNM), detected by the pharmacist each time medication was dispensed, as well as the perception of the pharmacist on the operability of the protocol were recorded. A total of 870 medications were dispensed, with 423 (48.6%) cases of lack of personalised medication information (IPM) being detected. PRM were detected in 10.11% of the dispensed medications, as well as 68 (7.81%) suspected RNM: safety (n = 35; 51.5%), effectiveness (n = 29; 42.6%) and necessity (n = 4; 5.8%). Almost two-thirds (65.21%) of the pharmacists said that the protocol is in operation. The designed protocol helped to detect deficiencies in the information to the patients about their medications, as well as the PRM and RNM, and is shown to be tool that is easy to use and apply.

    Analysing how systemic antibiotic agents were dispensed to outpatients in a Colombian population between January 2005 and December 2006 and assessing their economic cost as antibiotic use and abuse have been related to serious bacterial resistance. This was a descriptive observational study of antibiotic drug use; a database was compiled from medication usage records maintained by dispensing pharmacies in 10 Colombian cities regarding the total of users who had received some type of antibiotic. The defined daily dose (DDD) and cost per 1,000 inhabitants/day were assessed. The commonly used antibiotic associations were analysed. DDD was 1.58 per 1,000 inhabitants per day. The antibiotics most frequently prescribed were penicillin (amoxiciline; dicloxaciline), followed by first-generation cephalosporines and sulphonamides. Injectable antibiotic use was 10.4 % in 2005 and 9.3 % in 2006; an association of anti-bacterial agents was used for 11 % of the patients. Total antibiotic dispensation cost in 2005 was US$ 1,708,350 and cost per 1,000 inhabitants per day was US$ 1.13 in 2005 and US$ 1 in 2006. DDD per 1,000 inhabitants per day and cost per inhabitant per day was low compared to other countries.

    2017-07-01

    In this study, the effect of various parameters on the dispensed droplet size in microchannels based on the electrowetting on dielectric technique is experimentally investigated. A printed circuit board (PCB)-based microfluidic chip is used as a platform for the experiments. A crescent configuration for the channel electrodes is fabricated, which leads to a higher electrowetting force which improves the motion of the droplet. In addition, two electrode designs are proposed, which provide a nearly constant overlapping length on the reservoir electrode. The focus of this paper is on the geometry of the reservoir and the channel electrode; therefore, the channel dimensions, surface conditions, and applied voltage are kept constant. The experiments are performed for various reservoir liquid volumes and different electrode shapes of the reservoir and the microchannel. The results show that decreasing the length of the small reservoir electrode reduces the size of the dispensed droplet. It is also observed that using a channel electrode curved in the opposite direction of the droplet motion leads to a smaller dispensed droplet.

    To investigate the quality of drug interaction decision support in selected prescribing and dispensing software systems, and to compare this information with that found in a range of reference sources. A comparative study, conducted between June 2006 and February 2007, of the support provided for making decisions about 20 major and 20 minor drug interactions in six prescribing and three dispensing software systems used in primary care in Australia. Five electronic reference sources were evaluated for comparison. Sensitivity, specificity and quality of information; for major interactions: whether information on clinical effects, timeframe and pharmacological mechanism was included, whether management advice was helpful, and succinctness. Six of the nine software systems had a sensitivity rate > or = 90%, detecting most of the major interactions. Only 3/9 systems had a specificity rate of > or = 80%, with other systems providing inappropriate or unhelpful alerts for many minor interactions. Only 2/9 systems provided adequate information about clinical effects for more than half the major drug interactions, and 1/9 provided useful management advice for more than half of these. The reference sources had high sensitivity and in general provided more comprehensive clinical information than the software systems. Drug interaction decision support in commonly used prescribing and dispensing software has significant shortcomings.

    Objectives This study investigates utilisation patterns for prescription opioid analgesics in the Australian community and how these are associated with a framework of individual-level factors related to healthcare use. Methods Self-reported demographic and health information from participants in the 45 and Up Study cohort were linked to pharmaceutical claims from 2006–2009. Participants comprised 19,816 people with ≥1 opioid analgesic dispensing in the 12-months after recruitment to the cohort and 79,882 people not dispensed opioid analgesics. All participants were aged ≥45 years, were social security pharmaceutical beneficiaries, with no history of cancer. People dispensed opioid analgesics were classified as having acute (dispensing period osteoarthritis treatment, paracetamol use, and poor physical function were the strongest predictors for all opioid analgesic users. Conclusions People dispensed opioid analgesics were in poorer health, reported higher levels of distress and poorer functioning than people not receiving opioid analgesics. Varying dispensing profiles were evident among people dispensed opioid analgesics for persistent pain, with those receiving episodic and long-term treatment dispensed the strongest opioid analgesics. The findings highlight the broad range of factors associated with longer term opioid analgesics use. PMID:24312456

    Full Text Available Abstract Background Databases are frequently used for pharmacoepidemiological research. However, most of these databases consist either of prescribing, dispensing or administrative data and therefore lack insight in the interaction between the several health professionals around the patient. Methods To determine the success rate of linking records from the dispensing database of the Foundation for Pharmaceutical Statistics to the prescribing database of the second Dutch national survey of general practice, conducted by NIVEL (Netherlands Institute for Health Services Research, a deterministic record linkage approach was used with patient and prescription characteristics as matching variables between the two databases. Results The catchment area included 123 community pharmacies, 90 GP practices and approximately 170,000 unique patients. Overall 110,102 (64.8% unique patients were linked using the matching variables patient's gender, year of birth, the 4-digit part of the postal code, date of dispensing/prescribing and ATC-code. The final database contains of the 110,102 both prescribing data from 83 GP practices and dispensing data of 112 community pharmacies. Conclusion This study shows that linkage of dispensing to prescribing data is feasible with a combination of patient characteristics, such as gender, year of birth and postal code, and prescription characteristics like prescription date and ATC-code. We obtained a linkage proportion of 64.8% resulting in complete prescribing and dispensing history of 110,102 patients. This offers an opportunity to gain insight in the mechanisms and factors influencing drug utilisation in general practice.

    Private sector accredited drug dispensing outlets in Morogoro and pharmacies in Dar es Salaam, Tanzania. To assess 1) the level of knowledge about tuberculosis (TB) among dispensers in Tanzania's retail pharmaceutical sector; 2) practices related to identification of patients with suspected TB; 3) the availability of educational materials and training; and 4) the availability of first- and second-line anti-tuberculosis treatment in retail drug outlets. A cross-sectional descriptive study involving the administration of a structured questionnaire among drug dispensers in 122 pharmacies and 173 accredited drug dispensing outlets. Private retail drug outlets are convenient; most are open at least 12 h per day, 7 days/week. Although 95% of dispensers identified persistent cough as a symptom of TB, only 1% had received TB-related training in the previous 3 years; 8% of outlets stocked first-line anti-tuberculosis medicines, which are legally prohibited from being sold at retail outlets. The majority of respondents reported seeing clients with TB-like symptoms, and of these 95% reported frequently referring clients to nearby health facilities. Private retail pharmaceutical outlets can potentially contribute to TB case detection and treatment; however, a coordinated effort is needed to train dispensers and implement appropriate referral procedures.

    2005-04-01

    To modify a commercial xenon gas dispenser so that two xenon unit-dose vials could be combined with a modified dispenser to deliver a recommended dose. To maintain the same operating mechanism, changes were made only to the vial shield and the needle port of the original gas dispenser. The modified gas dispenser consisted of two puncture needles and two vial holders shielded with the same thickness of lead as the commercial dispenser. Our evaluation showed that the modified gas dispenser operated the same way as the commercial unit, and the average 133Xe residual activity in either one or two xenon unit-dose vials of the modified gas dispenser was not significantly different from that in one vial of the commercial xenon gas dispenser. The modified xenon gas dispenser allows the stock of xenon gas vials to be managed cost-effectively. The modified unit can be used to dispense two low-activity xenon gas vials to deliver a standard dose to a patient. Also, the modified gas dispenser can be used to combine different amounts of xenon activity in two unit-dose vials in order to customize the dose delivered to patients with special needs (e.g., obese patients). Our modified device can also function as a single-dose dispenser by placing an empty vial alongside the unit-dose vial of radioactive xenon gas.

    Over two growing seasons, Isomate GBM-Plus tube-type dispensers releasing the major pheromone component of grape berry moth, Paralobesia viteana (Clemens) (Lepidoptera: Tortricidae), were evaluated in vineyards (Vitis spp.) in Michigan, New York, and Pennsylvania. Dispensers were deployed in three different density-arrangement treatments: 124 dispensers per ha, 494 dispensers per ha, and a combined treatment with 124 dispensers per ha in the vineyard interior and 988 dispensers per ha at the vineyard border, equivalent to an overall density of 494 dispensers per ha. Moth captures and cluster infestation levels were compared at the perimeter and interior of vineyards receiving these different pheromone treatments and in vineyards receiving no pheromone. Orientation of male moths to pheromone-baited traps positioned at the perimeter and interior of vineyards was reduced as a result of mating disruption treatments compared with the nontreated control. These findings were consistent over both years of the study. Disruption of male moth captures in traps varied from 93 to 100% in treated vineyards, with the 494 dispensers per ha application rates providing significantly higher level of disruption than the 124 dispensers per ha rate, but only in 2007. Measurements of percentage of cluster infestation indicated much higher infestation at perimeters than in the interior of the vineyards in all three regions, but in both sample positions there was no significant effect of dispenser density on cluster infestation levels in either year. The contrasting results of high disruption of moth orientation to traps in vineyards that also had low levels of crop protection from this pheromone treatment are discussed in the context of strategies to improve mating disruption of this tortricid pest.

    In routine radiopharmaceutical Iodine-131 ({sup 131}I) dispensing, the amount of radiation dose received by the personnel depends on the distance between the personnel and the source, the time spent manipulating the source and the amount of shielding used to reduce the dose rate from the source. The novel iRAD-I131 dispenser using recycle {sup 131}I liquid lead pot will lead into low cost production, less maintenance and low dose received by the personnel that prepared the {sup 131}I. The new fabricated of low cost {sup 131}I dispenser was tested and the dose received by personnel were evaluated. The body of lead material is made from 2.5 cm lead shielded coated with epoxy paint to absorb the radiation dose up to 7.4 GBq of {sup 131} I. The lead pot was supported with two stainless steel rod. The Optically Stimulated Luminescence (OSL) nanodot was used in this study to measure the dose rate at both extremities for every personnel who prepared the {sup 131}I. Each OSL nanodot was attached at the fingertip. Three different personnel (experienced between one to ten years above in preparing the radiopharmaceuticals) were participated in this study. The average equivalent dose at right and left hand were 122.694 ± 121.637 µSv/GBq and 77.281 ± 62.146 µSv/GBq respectively. This study found that the dose exposure received using iRAD-I131 was less up to seven times compared to the conventional method. The comparison of experimental data using iRAD-I131 and established radiopharmaceutical dispenser was also discussed. The innovation of {sup 131}I dispenser is highly recommended in a small radiopharmaceutical facility with limited budget. The novel iRAD-I131 enables implementation of higher output liquid dispensing with low radiation dose to the personnel.

    We aimed to assess the impact of an automated dispensing system on the incidence of medication errors related to picking, preparation, and administration of drugs in a medical intensive care unit. We also evaluated the clinical significance of such errors and user satisfaction. Preintervention and postintervention study involving a control and an intervention medical intensive care unit. Two medical intensive care units in the same department of a 2,000-bed university hospital. Adult medical intensive care patients. After a 2-month observation period, we implemented an automated dispensing system in one of the units (study unit) chosen randomly, with the other unit being the control. The overall error rate was expressed as a percentage of total opportunities for error. The severity of errors was classified according to National Coordinating Council for Medication Error Reporting and Prevention categories by an expert committee. User satisfaction was assessed through self-administered questionnaires completed by nurses. A total of 1,476 medications for 115 patients were observed. After automated dispensing system implementation, we observed a reduced percentage of total opportunities for error in the study compared to the control unit (13.5% and 18.6%, respectively; perror (20.4% and 13.5%; perror showed a significant impact of the automated dispensing system in reducing preparation errors (perrors caused no harm (National Coordinating Council for Medication Error Reporting and Prevention category C). The automated dispensing system did not reduce errors causing harm. Finally, the mean for working conditions improved from 1.0±0.8 to 2.5±0.8 on the four-point Likert scale. The implementation of an automated dispensing system reduced overall medication errors related to picking, preparation, and administration of drugs in the intensive care unit. Furthermore, most nurses favored the new drug dispensation organization.

While resistance to older antibiotics is increasing, development of newer molecules has stalled. Resistance to the existing antibiotics that is largely driven by their high-volume use is a global public health problem. Uganda is one of the countries where prescription-only drugs, including antibiotics, can be obtained over the counter. We determined the rate of antibiotic dispensing and use in Uganda. Methods: The study utilized a descriptive cross-sectional study design to determine the number of antibiotic "prescribed" daily doses per 1,000 clients. Data were collected from one health center II, eight general/district hospitals, one national referral hospital, and 62 registered community pharmacies. From each study site, data were collected for five consecutive days over the months of November 2011 to January 2012. Results: The overall antibiotic issue rate was 43.2%. Amoxicillin, metronidazole, ciprofloxacin, sulfamethoxazole–trimethoprim, cloxacillin, and ampicillin, belonging to the WHO anatomical therapeutic chemical classifications of penicillin with extended spectra, imidazole derivatives, fluoroquinolones, and sulfonamide–trimethoprim combinations, constituted 70% of the issued antibiotics. About 41% of antibiotics were issued over the counter. At community pharmacies, where 30% of antibiotic dispensing occurred, the number of prescribed daily doses/1,000 antibiotic clients was 4,169 compared to 6,220, 7,350 and 7,500 at general/district hospitals, the national referral hospital, and the health center, respectively.

    Full Text Available Jacob G Moroshek1,2 1Bioinformatics and Computational Biology, 2Carlson School of Management, University of Minnesota, Minneapolis, MN, USA Background: Physician dispensing, different from pharmacist dispensing, is a way for practitioners to supply their patients with medications, at the point of care. The InstyMeds dispenser and logistics system can automate much of the dispensing, insurance adjudication, inventory management, and regulatory reporting that is required of physician dispensing. Objective: To understand the percentage of patients that exhibit primary adherence to medication in the outpatient setting when choosing InstyMeds. Method: The InstyMeds dispensing database was de-identified and analyzed for primary adherence. This is the ratio of patients who dispensed their medication to those who received an eligible prescription. Results: The average InstyMeds emergency department installation has a primary adherence rate of 91.7%. The maximum rate for an installed device was 98.5%. Conclusion: Although national rates of primary adherence have been found to be in the range of 70%, automated physician dispensing vastly improves the rate of adherence. Improved adherence should lead to better patient outcomes, fewer return visits, and lower healthcare costs.

    To evaluate the drug dispensing practices and patients' knowledge on drug use among the outpatients and to identify and analyze the problems in drug prescribing and dispensing. A prospective cross-sectional descriptive study was conducted using World Health Organization (WHO) core drug use indicators from July 13, 2008 to August 15, 2008 in Manipal Teaching Hospital, Pokhara, Nepal. A total of 4231 prescriptions were encountered with the total of 10591 drugs prescribed. The average number of drug per prescription was 2.5. Only 13% (n=10591) of drugs were prescribed by generic name. Percentage of drug prescribed from WHO model list of Essential drugs, Essential drug list of Nepal and Nepalese National Formulary was 21.7%, 32.8% and 42.3% respectively. Antibiotics and injections encountered were 28.3% and 3.1% respectively. Average cost per prescription was found to be Nepalese Rupees (NRs) 285.99 (US $ 3.73). Patient knowledge on correct use of drugs and appropriate labeling was found to be 81% and 1.4% respectively. Average dispensing time per prescription was 52 seconds. The finding from current study shows a trend towards irrational prescribing and dispensing. Hence, there is a need for effective intervention programme to encourage the physicians and dispensing pharmacists in promoting more rational drug use.

    To date, in modern agriculture, biological control strategies are increasingly becoming the preferred pest management approach. However, the success of microbiological control agents (MCAs) largely depends on efficient dissemination into the crop. The pollinator-and-vector technology employs pollinating insects like bees for a better dissemination. In this study, a new dispenser for bumblebee workers of Bombus terrestris L. was developed. Binab-T-vector and Prestop-Mix were used as two typical MCA products for dissemination. In a first series of experiments in the laboratory for optimisation, the newly developed dispenser was a two-way type dispenser, 20 cm long, with two rectangular compartments and different entrance and exit holes. In addition, the amounts of MCA loaded on the workers were 10 times higher with the new dispenser as compared with the side-by-side passageway (SSP) dispenser. Typically, the highest amounts were recovered from the thorax and legs of the workers. In a second series of experiments under greenhouse conditions with the use of queen-right B. terrestris hives, successful dissemination in strawberry flowers was obtained at different distances from the hive (0-8 m, 8-18 m and 18-21 m), and the workers inoculated the first, second and third flowers that were consecutively visited. In addition, the new dispenser caused no adverse effects on worker foraging intensity, whereas a dramatic reduction was scored with an SSP dispenser. Finally, the data suggested that it is necessary to refill the newly developed dispenser at 3 day intervals. The results demonstrated that, with the use of the newly developed dispenser, bumblebee workers carried high amounts of MCA, and this resulted in a successful dissemination of MCA into strawberry flowers.

    Full Text Available Purpose. The study aimed to determine the extent of and factors influencing the prescribing of injections for the treatment of mild/moderate community acquired pneumonia (CAP in Mongolia.Methods. Questionnaires were developed and administered to medication providers (34 Pharmacists, 27 pharmacy technicians and prescribers (22 general doctors and 49 medical specialists working in Mongolia.Results. Cefalosporins were prescribed for patients with mild pneumonia and doctors tended to prescribe injectable cefalosporins (cefazolin rather than oral dosage forms. This was supported by the questionnaire study with pharmacists and pharmacy technicians. Additionally, 23 pharmacists and pharmacy technicians indicated that OTC injectable cefalosporins (37.7% and injectable aminopenicillins (33,9% were frequently sold by pharmacies for the treatment of mild/moderate CAP. Doctors and particularly pharmacists in the questionnaire studies indicated choosing an injection was to avoid non-compliance problems.Conclusion. High levels of injectable prescribing of antibiotics were found in non-hospitalized patients with CAP in Mongolia. This prevalence level indicated that inappropriate injection prescribing is a public health hazard for Mongolia and requires consideration by the appropriate authorities.

    Our objective was to elicit patient preferences for transferring elements of hearing aid provision from the medical sector [Ear Nose and Throat (ENT) specialists and audiological centers] to private hearing aid dispensers, and to understand the trade-offs between different elements of hearing aid provision. A discrete choice experiment was administered from 150 hearing-impaired persons in the Netherlands. Mean age was 71 (range 18-95) and 57% were male. Participants preferred the initial assessment at the dispenser, higher accuracy in identifying persons in need of medical care, shorter duration of the total hearing aid provision, and a follow-up at the ENT specialist. They required compensation of at least euro 17 per 2 mo extra duration, euro 54 for an initial assessment at the ENT specialist, euro 119 per 10% decrease in accuracy, and euro 227 to forgo the follow-up at the ENT specialist. Preferences were influenced by sex, age, educational level, and experience with hearing aid provision. Hearing-impaired persons are receptive to transferring elements of hearing aid provision from the medical sector to private dispensers. Although safety and efficiency issues should also be considered, from the present study we can conclude that in the organization of hearing aid provision hearing-impaired persons prefer an initial assessment at a private dispenser when the dispenser is at least 95% as accurate as the ENT specialist, and prefer a follow-up visit at the ENT specialist.

    Although pediatric asthma continues to be a highly studied disease, data to suggest clear strategies to decrease asthma related revisits or readmissions is lacking. The purpose of our study was to assess the effect of emergency department (ED) direct dispensing of beta-agonist metered dose inhalers on pediatric asthma ED revisit and readmission rates. We conducted a retrospective cohort study of pediatric patients discharged from the pediatric ED with a diagnosis of asthma. Our primary outcome measured the rate of asthma revisits to the ED or admissions to the hospital within 28 days. Logistic regression analysis was used to assess ED beta-agonist MDI dispensing and revisit and/or readmission as the outcome. A total of 853 patients met eligibility for inclusion in the study, with 657 enrolled in the Baseline group and 196 enrolled in the ED-MDI group. The Baseline group experienced a revisit and readmission rate of 7.0% (46/657) versus 2.6% (5/196) in the ED-MDI group, (p = 0.026). ED direct dispensing of MDIs was found to be independently associated with a decreased risk of revisit or readmission (odds ratio 0.37; 95% confidence interval 0.14-0.95). In our study, ED direct dispensing of beta-agonist MDIs resulted in a reduction in 28-day revisit and readmission to the hospital. Further studies should be performed to evaluate the economic impact of reducing these revisits and readmissions against the costs of maintaining a dispensing program. Our findings may support modification of asthma programs to include dispensing MDIs from the emergency department.

    Few studies have explored the microbial contamination of glove boxes in clinical settings. The objective of this observational study was to investigate whether a new glove packaging system in which single gloves are dispensed vertically, cuff end first, has lower levels of contamination on the gloves and on the surface around the box aperture compared with conventional glove boxes. Seven participating sites were provided with vertical glove dispensing systems (modified boxes) and conventional boxes. Before opening glove boxes, the surface around the aperture was sampled microbiologically to establish baseline levels of superficial contamination. Once the glove boxes were opened, the first pair of gloves in each box was sampled for viable bacteria. Thereafter, testing sites were visited on a weekly basis over a period of six weeks and the same microbiological assessments were made. The surface near the aperture of the modified boxes became significantly less contaminated over time compared with the conventional boxes (Pcontamination around the aperture. Overall, gloves from modified boxes showed significantly less colony-forming unit contamination than gloves from conventional boxes (Pcontamination. This simple improvement to glove box design reduces contamination of unused gloves. Such modifications could decrease the risk of microbial cross-transmission in settings that use gloves. However, such advantages do not substitute for strict hand hygiene compliance and appropriate use of non-sterile, single-use gloves. Copyright © 2016 The Healthcare Infection Society.

    Flexible electroluminescent (EL) lamps are fabricated onto woven textiles using a novel dispenser printing process. Dispenser printing utilizes pressurized air to deposit ink onto a substrate through a syringe and nozzle. This work demonstrates the first use of this technology to fabricate EL lamps. The luminance of the dispenser printed EL lamps is compared to screen-printed EL lamps, both printed on textile, and also commercial EL lamps on polyurethane film. The dispenser printed lamps are shown to have a 1.5 times higher luminance than the best performing commercially available lamp, and have a comparable performance to the screen-printed lamps.

    Full Text Available The aim of the present study was to evaluate the education of Pharmaceutical Technicians for the activity of responsible dispensing. Based on a questionnaire with open and closed questions, the study sought to characterize the students, identify knowledge and attitudes regarding the Rational Use of Medications while addressing the limits and possibilities of professional and ethical dispensing in practice. In addition, a group dynamics session - focus group - was held as a forum for debate on responsible dispensing. The results showed that students tended to be mature, currently employed and were predominately women. Displaying adequate knowledge on Rational Use of Medications and of the corresponding legislation, the students reported difficulties exercising compatible practice. While the diagnosis pointed to the need for student preparation to enable ethical dispensing, the Focus Group highlighted the possibility for inclusion of a forum for reflection and debate on the ethics of dispensing as part of the Pharmaceutical Technician training.O presente trabalho tem como proposta avaliar a formação do Técnico em Farmácia para o exercício da dispensação responsável.

    Measure and compare the percentage of prescriptions fully dispensed to persons with and without Popular Health Insurance (SPS in Spanish) who use ambulatory and general hospital services associated with the Mexico State Health Services (SESA in Spanish), and taking into account insurance status. SESA user satisfaction was also measured with respect to access to medication. Information for the study was taken from four surveys of SESA ambulatory and hospital units that included probabilistic samples with state representativity. Samples of ambulatory units were selected by stratification according to level of care and association to the SPS service network. The findings indicate that the percentage of prescriptions fully dispensed in SESA ambulatory units has improved, reaching approximately 90%, especially among those units offering services to persons affiliated with SPS. Nevertheless, these percentages continue to be lower than those of ambulatory units associated with social security institutions. Percentages of prescriptions fully dispensed have also improved in SESA hospital units, but continue to be relatively low. In nearly all states, as the percentage of prescriptions fully dispensed has increased, user satisfaction with access to medication has also improved. In 2006 more than 50% of the states had high levels of fully dispensed prescriptions among persons with SPS (> or =90%). The more significant problem exists among hospitals, since only 44% of users who received a prescription in SESA hospitals in 2006 had their prescriptions fully dispensed. This finding requires a review of SPS medication policies, which have favored highly prescribed low-cost medications at ambulatory services at the expense of higher cost and more therapeutically effective medications for hospital care, the latter having a greater impact on household budgets.

    Full Text Available OBJECTIVES: This study investigates utilisation patterns for prescription opioid analgesics in the Australian community and how these are associated with a framework of individual-level factors related to healthcare use. METHODS: Self-reported demographic and health information from participants in the 45 and Up Study cohort were linked to pharmaceutical claims from 2006-2009. Participants comprised 19,816 people with ≥1 opioid analgesic dispensing in the 12-months after recruitment to the cohort and 79,882 people not dispensed opioid analgesics. All participants were aged ≥45 years, were social security pharmaceutical beneficiaries, with no history of cancer. People dispensed opioid analgesics were classified as having acute (dispensing period <90 days, episodic (≥90 days and <3 'authority' prescriptions for increased quantity supply or long-term treatment (≥90 days and ≥3 authority prescriptions. RESULTS: Of participants dispensed opioid analgesic 52% received acute treatment, 25% episodic treatment and 23% long-term treatment. People dispensed opioid analgesics long-term had an average of 14.9 opioid analgesic prescriptions/year from 2.0 doctors compared with 1.5 prescriptions from 1.1 doctors for people receiving acute treatment. People dispensed opioid analgesics reported more need-related factors such as poorer physical functioning and higher psychological distress. Long-term users were more likely to have access-related factors such as low-income and living outside major cities. After simultaneous adjustment, association with predisposing health factors and access diminished, but indicators of need such as osteoarthritis treatment, paracetamol use, and poor physical function were the strongest predictors for all opioid analgesic users. CONCLUSIONS: People dispensed opioid analgesics were in poorer health, reported higher levels of distress and poorer functioning than people not receiving opioid analgesics. Varying dispensing

    Published surveys depicting the increase in the incidence of food allergy, especially peanut or tree nut allergy, in children have not reported any differences in race, ethnicity, or socioeconomic status. To analyze the demographics of schoolchildren with diverse racial, ethnic, and socioeconomic characteristics dispensed injectable epinephrine. School nurses in 44 schools enrolling 21,875 students recorded the characteristics of students dispensed injectable epinephrine in the 2003-2004 school year. Surveyed school districts included 2 affluent suburban districts enrolling 5,855 students (> 92% white) and 1 urban district enrolling 16,020 students (60% nonwhite). A total of 181 students in all 3 districts were dispensed injectable epinephrine; 118 of these children had peanut or tree nut allergy. Males were more likely to be dispensed injectable epinephrine than females (odds ratio [OR], 1.44; P < .02). Whites were more likely to have been dispensed injectable epinephrine than nonwhites (OR, 4.76; P < .001). Whites were nearly 5 times more likely to be dispensed injectable epinephrine for peanut or tree nut allergy than nonwhites (OR, 4.5; P < .001). Most students (75%) dispensed injectable epinephrine for peanut or tree nut allergy were enrolled in prekindergarten through grade 5 (P < .001). Whites were more likely than nonwhites to be dispensed injectable epinephrine for stinging insect allergy (OR, 8.7; P < .001). This study found significant racial, ethnic, and socioeconomic differences in the prevalence of childhood allergic disorders, especially peanut or tree nut allergy, requiring prescribed injectable epinephrine in a school setting. Additional studies are needed to determine whether minority children are being underdiagnosed or undertreated for allergic disorders requiring injectable epinephrine or whether they truly have a lower incidence of such allergic disorders.

    More and more Chinese drink hot water from water dispensers while many children were scalded due to this change. The present study aimed to propose a feasible strategy for prevention. A retrospective study was conducted for all water dispensers related pediatric burns admitted to Changhai Hospital from January 2005 to December 2009. The number of new cases and incidences of pediatric burns due to hot water from water dispensers was significantly increasing year after year. In the total 238 involved cases, 175 cases happened on males and 78.9% were at the age of 1 - 4 years. The burn areas were mainly located in upper extremities. All water dispensers in the surveyed families had no isolate protection devices and 85.2% of their locations were easy for children to reach. Nearly half of the children were in the same room with their guardians when injured. Total 196 burned children were playing the taps of water dispensers before injured, unfortunately, 80.6% of them have not been stopped until burned. As the kind of burns is quite serious and with bad outcome, some recommendations should be followed, such as buying water dispensers with protection devices, keeping children from touching them and so on.

    A reproducible method of dosing pigments can be beneficial and more efficient in the current colour matching procedure in maxillofacial prosthetics. In this study the reproducibility and applicability for pigment dosing of a commercial available EFD(®) dispenser were tested. The reproducibility of a Performus™ II type EFD(®) dispenser was tested by repeating dosing experiments with a set of eight syringes filled with pigment pastes (Factor 2; Flagstaff, USA). To evaluate conventional colour matching, four conventionally colour matched samples were polymerized and compared to the original ones. To investigate the reproducibility of the dispenser in practice, a fifth recipe was dispensed 10 times and colour differences were evaluated visually and as well calculated from measurements with a colour and translucency meter (CTM, PBSensortechnology bv). All dispensed amounts of pigment pastes showed a coefficient of variation in weight of less than 10 %. Evaluating the reproductions of four skin batches compared to the original batches, a ∆E2000 colour difference of 3-7 was measured. Evaluating ten reproductions of one skin coloured batch made with the dispenser, color difference ∆E2000 values compared to the average L*a*b* values, were less than 2 and no visual colour differences could be estimated. Conform these results, low colour differences could be measured with the CTM, indicating no visually observable consequences. Despite the estimated coefficient of variation, the reproducibility of the EFD(®) dispenser in terms of colour difference ∆E2000 of successive dispensing is applicable for colour reproduction in facial prosthetics. Segregation of the current color pastes in due time needs to be taken into consideration.

    The combined activity of the 1.1.1-cryptand and of a dicopper(II) bistren cryptate complex including chloride makes the Cl(-) ion be continuously and slowly delivered to the solution, without any external intervention. The 1.1.1-cryptand slowly releases OH(-) ions, according to a defined kinetics, and each OH(-) ion displaces a Cl(-) ion from the cryptate. Chloride displacement induces a sharp colour change from bright yellow to aquamarine and can be conveniently monitored spectrophotometrically, even in diluted solutions. The 1.1.1-cryptand is the motor of a molecular dispenser (the dicopper(II) cryptate) delivering chloride ion automatically, from the inside of the solution.

    Sub-Saharan Africa is the world region with the greatest number of people eligible to receive antiretroviral treatment (ART). Less frequent dispensing of ART and community-based ART-delivery models are potential strategies to reduce the load on overburdened healthcare facilities and reduce the barriers for patients to access treatment. However, no large-scale trials have been conducted investigating patient outcomes or evaluating the cost-effectiveness of extended ART-dispensing intervals within community ART-delivery models. This trial will assess the clinical effectiveness, cost-effectiveness and acceptability of providing ART refills on a 3 vs. a 6-monthly basis within community ART-refill groups (CARGs) for stable patients in Zimbabwe. In this pragmatic, three-arm, parallel, unblinded, cluster-randomized non-inferiority trial, 30 clusters (healthcare facilities and associated CARGs) are allocated using stratified randomization in a 1:1:1 ratio to either (1) ART refills supplied 3-monthly from the health facility (control arm), (2) ART refills supplied 3-monthly within CARGs, or (3) ART refills supplied 6-monthly within CARGs. A CARG consists of 6-12 stable patients who meet in the community to receive ART refills and who provide support to one another. Stable adult ART patients with a baseline viral load alive and retained in care 12 months after enrollment. Secondary outcomes (measured at 12 and 24 months) are the proportions achieving virological suppression, average provider cost per participant, provider cost per participant retained, cost per participant retained with virological suppression, and average patient-level costs to access treatment. Qualitative research will assess the acceptability of extended ART-dispensing intervals within CARGs to both providers and patients, and indicators of potential facility-level decongestion due to the interventions will be assessed.

    This paper presents a novel plug-in nanoliter liquid dispensing system with a plug-and-play interface for simple and reversible, yet robust integration of the dispenser. A plug-in type dispenser was developed to facilitate assembly and disassembly with an actuating part through efficient modularization. The entire process for assembly and operation of the plug-in dispenser is performed via the plug-and-play interface in less than a minute without loss of dispensing quality. The minimum volume of droplets pneumatically dispensed using the plug-in dispenser was 124 nl with a coefficient of variation of 1.6%. The dispensed volume increased linearly with the nozzle size. Utilizing this linear relationship, two types of multinozzle dispensers consisting of six parallel channels (emerging from an inlet) and six nozzles were developed to demonstrate a novel strategy for volume gradient dispensing at a single operating condition. The droplet volume dispensed from each nozzle also increased linearly with nozzle size, demonstrating that nozzle size is a dominant factor on dispensed volume, even for multinozzle dispensing. Therefore, the proposed plug-in dispenser enables flexible design of nozzles and reversible integration to dispense droplets with different volumes, depending on the application. Furthermore, to demonstrate the practicality of the proposed dispensing system, we developed a pencil-type dispensing system as an alternative to a conventional pipette for rapid and reliable dispensing of minute volume droplets.

    Australian health practitioner registration is national, whereas legislation regarding the handling of medicines is governed by individual States and Territories. To align with the July 2010 national registration scheme some legislative modifications were made concerning scheduled drugs and poisons, but many differences between jurisdictions remain. In Queensland, the Health (Drugs and Poisons) Regulation 1996 (Qld) allows for dispensing of controlled drugs written by interstate prescribers but not lower scheduled specified restricted and regulated restricted drugs. The aim of this study was to assess awareness of seemingly counterintuitive legislation by pharmacists practising in South-East Queensland. Of 125 Gold Coast pharmacies contacted, 54 (43.2%) agreed to participate. The majority of pharmacists (88.9%) had good knowledge regarding controlled drugs. In contrast, they demonstrated confusion regarding specified restricted and regulated restricted drugs (51.9% correct awareness). Uniform legislation between jurisdictions or more intuitive legislation would ease practitioner confusion.

    Indiscriminate use of antibiotics contributes to a global spread of antimicrobial resistance. Previous studies showed an excessive consumption of antibiotics purchased without medical prescription from community pharmacies, mainly in developing countries. There is a shortage of studies revealing the role of community pharmacists in the overuse of antibiotics. Our objective is to study the dispensing policy of non-medical prescription antibiotics in community pharmacies, assessing the possible influence of the socio-economic level of the area over this practice. A cross-sectional study was conducted between February and May 2011 among 100 pharmacists working in Beirut's pharmacies and its suburbs. Pharmacies were divided into 2 groups according to the socio-economic level of the population living in the pharmacy area. A self-administered questionnaire was filled by pharmacists. Over-the-counter antibiotic availability existed in both higher and lower socio-economic areas: on the whole, 32% of antibiotics were dispensed without medical prescription, with higher frequency in lower socio-economic areas (p=0.003). Dispensing injectable antibiotics without medical prescription was significantly higher in lower socio-economic areas (p=0.021), as well as dispensing an association of 2 antibiotics without medical prescription (p=0.001). Pharmacists working in lower socio-economic areas recommended more frequent antibiotics to children and the elderly (p<0.001 and p=0.004, respectively). Dispensing antibiotics without medical prescription in Beirut community pharmacies is a common practice, particularly in lower socioeconomic areas. This public health problem should be addressed at the social, educational, and legislative levels. Copyright © 2014 King Saud Bin Abdulaziz University for Health Sciences. Published by Elsevier Ltd.

    Full Text Available Objectives: The purpose of this study was to conduct a health technology assessment (HTA of automated dose dispensing in the Danish primary health care sector. The present article answers the sub question of how various groups of actors spoke about and understood the shaping of automated dose dispensing (positioning in discourses.Methods: The project utilized two methods: 11 qualitative research interviews with selected key actors and a net-based qualitative questionnaire of 97 selected practitioners.Results: Three main types of discourse were identified with respect to the development of automated dose dispensing, namely ‘optimistic’, ‘sceptical’ and ‘pragmatic’. A wide diversity of opinion about automated dose dispensing was identified among the three discourses and their attendant scenarios. A number of factors are found in all three types of discourse, and are therefore considered to express common recommendations for decision makers and practitioners. These factors are described in the article.Conclusions: The article argues in favour of HTA, which to a great extent clarifies and initiates the perspectives of various groups of actors about the same technology. Our analyses show that conscious strategies must be employed to make the technology work successfully with the actors involved. The preferences, ideas and proposals for future actions and initiatives identified in the project could be the basis for defining future development strategies.

    There has been limited assessment of the impact that automated medication dispensing machines have on the medication administration process, particularly in Australian emergency departments. The aim of this study is to examine the change in medication retrieval times, number of medications retrieved and staff perceptions before and after the installation of automated dispensing machines in an Australian emergency and trauma centre. A time and motion method recorded the time taken and number of medications retrieved from the medication room by emergency department staff, before and after the installation of two automated dispensing machines. Surveys were administered to staff members to elicit the perceived impact on clinical practice, utilising 5-point Likert scales. A total of 954 medication retrievals (1030 medications) were recorded in the pre-implementation period and 842 (991 medications) in the post-implementation period. The mean time taken to retrieve any medication was significantly longer in the post-implementation period (+5.7s; ptime increased by 26.9s (pmachines improve knowledge of medications on imprest (p=0.03) and reduced medication retrieval time (pmachines for Schedules 2, 3, 4 and unscheduled medications, but quicker for Schedule 8 and 11 medications in an Australian emergency and trauma centre. Although retrieving medications took slightly longer overall, staff believed automated dispensing machines save time. Copyright © 2016 College of Emergency Nursing Australasia.

    Full Text Available Cribbing is an oral stereotypy, tends to develop in captive animals as a means to cope with stress, and may be indicative of reduced welfare. Highly energetic diets ingested in a short time are one of the most relevant risk factors for the development of cribbing. The aim of this study was to verify whether feeding cribbing horses through a dispenser that delivers small quantities of concentrate when activated by the animal decreases cribbing behaviour, modifies feeding behaviour, or induces frustration. Ten horses (mean age 14 y, balanced for sex, breed, and size (mean height 162 cm, were divided into two groups of 5 horses each: Cribbing and Control. Animals were trained to use the dispenser and videorecorded continuously for 15 consecutive days from 1 h prior to feeding to 2 h after feeding in order to measure their behaviours. The feed dispenser, Quaryka®, induced an increase in time necessary to finish the ration in both groups of horses (P<0.05. With Quaryka, cribbers showed a significant reduction of time spent cribbing (P<0.05. After removal of the feed dispenser (Post-Quaryka, cribbing behaviour significantly increased. The use of Quaryka may be particularly beneficial in horses fed high-energy diets and ingesting the food too quickly.

    Sabrina Kartmann

    2015-04-01

    Full Text Available We present a miniaturized, disposable, normally-closed electromagnetic dispensing valve for the microliter range to process 96-well plates. The novel injection-molded valve is designed to fit into a 9 mm grid to realize an eight channel dispensing head, enabling the serial processing of well plates row-by-row. The presented dispensing valve design originates from a miniaturization study of a previously developed functional model. The outer diameter of the valve, including all actuating components, was reduced by 8 mm to an overall diameter of 8.5 mm without compromising the performance. Additionally, the actuation current of the valve could be reduced to 5 A. The valve is characterized for a volume range between 840 nL and 5.3 μL. The performance of the injection molded valve is competitive to commercially available dispensing valves, featuring the advantages of low fabrication costs, disposability, low mounting size, easy handling, and super silent actuation.

    The prevalence of allergic diseases has increased over the last 20 years in the Western world. Reports on the growing use of adrenaline auto-injectors (EpiPen and EpiPen Jr) in several countries may point to increased rates of anaphylactic reactions, increased awareness of the risk of anaphylaxis or both. To evaluate the dispensing rate of EpiPen units in Israel from 1997 to 2004. The database of the General Health Services (Clalit) was searched to determine the number of EpiPen units dispensed each year from 1997 to 2004. Data on mortality from anaphylaxis were derived from the Central Bureau of Statistics using International Classification of Diseases, 10th revision codes. The dispensing rate of EpiPen units rose gradually from 1689 in 1997 to 2981 in 2004; an overall increase of 76%. No case of death from anaphylaxis was reported from 1998 to 2000. The dispensing rate of adrenaline auto-injectors has increased considerably over the last 8 years in Israel, although to a lesser degree than in other countries. This is probably a reflection of updated medical policies, in accordance with the clinical guidelines for the management of anaphylaxis and improved public education. Further studies are needed to determine the prevalence of anaphylactic reactions in Israel.

    Yasuda, Takashi; Harada, Shouhei; Daimon, Katsuya

    We have designed a novel microfluidic dispensing device using automatic droplet transportation on a wettability gradient surface that is sequentially followed by electrowetting-based liquid handling. While a droplet moves along the wettability gradient in a main channel, a portion of the droplet is drawn into a side channel and stored in a reservoir temporarily. Next, the stored liquid is dispensed into a mixing channel when a voltage is applied between two electrodes. The fabricated device succeeded in dispensing two liquids of different nanoscale volumes after extracting them from a microscale volume droplet.

    Liquid antimicrobial soaps are commonly used in the dental health care setting for hand washing to minimize the potential spread of infectious agents to health care workers and patients. The purpose of the current study was to evaluate possible bacterial contamination of antimicrobial liquid soap dispensers located in 2 institutional comprehensive dental care clinics. Fourteen soap dispensers and 16 original stock containers were sampled. A 1-milliliter aliquot was diluted in 10 mL of phosphate buffer (Tween-80; Acros). Serial dilutions were plated in duplicate on neutralizing agar and incubated for 7 days. Molecular identification was performed using 500 base pair comparisons of 16S ribosomal ribonucleic acid sequencing. Taq polymerase chain reaction was performed with sequence-specific primers for Raoultella species. Bacterial growth was observed at 18 hours for 57% (8 of 14) of soap dispenser samples. Bacterial densities ranged from 4 × 10(2) to 6 × 10(9) colony-forming units per milliliter. Original commercial containers exhibited no growth. Isolates were identified as Raoultella (Klebsiella) planticola. This is the first study to the authors' knowledge indicating recovery of R. planticola from antimicrobial liquid soap dispensers. R. planticola is a recognized environmental opportunistic pathogen that potentially poses a health concern. These findings indicate compliance problems with infection prevention recommendations and support the US Centers for Disease Control and Prevention's recommendation that dispensers should not be topped off. High bacterial loads of R. planticola are inconsistent with infection control practices and are a concern because transmission and possible infection to the health care worker or the patient may occur.

    The implementation of carousel dispensing technology (CDT) at a university medical center pharmacy and the associated changes in drug distribution are described. An evaluation of CDT was conducted in three phases: before implementation, during implementation, and after implementation. The preimplementation phase consisted of data collection and facility planning leading up to the physical installation. The implementation phase included the physical installation, carousel medication assignment, and user training. The postimplementation phase included data collection and analysis. The data collected were used to compare preimplementation and postimplementation time studies, labor requirements, inventory turns, and accuracy rates. The estimated labor savings comparing the preimplementation and postimplementation time studies for automated dispensing cabinet (ADC) refills, first-dose requests, supplemental cart fill, and medication procurement totaled 2.6 full-time equivalents (FTEs). After departmental reorganization, a net reduction of 2.0 technician FTEs was achieved. The average turnaround time for stat medication requests using CDT was 7.19 minutes, and the percentage of doses filled in less than 20 minutes was 95.1%. After implementing CDT, the average accuracy rate for all dispense requests increased from 99.02% to 99.48%. The inventory carrying cost was reduced by $25,059. CDT improved the overall efficiency and accuracy of medication dispensing in a university medical center pharmacy. Workflow efficiencies achieved in ADC refill, first-dose dispensing, supplemental cart fill, and the medication procurement process allowed the department to reduce the amount of technician labor required to support the medication distribution process, as well as reallocate technician labor to other areas in need.

    To compare annual and monthly prevalence of psychotropic drug (PD) dispensing and the number and duration of psychotropic treatment episodes among people with and without cancer over a 2-year follow-up. We studied the following two cohorts of adult patients affiliated with the National Health Insurance Fund (NHIF): cancer patients followed for 2 years after diagnosis and individuals without cancer matched to cancer patients. Using information about anxiolytic, hypnotic, antidepressant, and antipsychotic dispensing in community pharmacies, we applied conditional log-binomial regressions to estimate adjusted relative risks for monthly dispensing of PDs. Annual prevalence of PD dispensing-all categories included-among cancer patients was significantly higher for almost all the categories we studied than among individuals without cancer. Monthly prevalence of anxiolytic/hypnotic dispensing started to rise several months before diagnosis and peaked immediately after. Among patients with cancer and their matched controls, treatment duration exceeded 1 month for hypnotics in 40 and 35 %, respectively (p < 0.01), and 3 months for anxiolytics in 23 and 23 % (p = 0.8); it was less than 6 months for antidepressants in 76 and 75 % (p = 0.5). Prevalence of psychotropic treatment was higher among cancer patients than among persons without cancer. Psychotropic treatment duration was not in line with recommendations for significant fractions of cancer patients or their controls. Training of health professionals involved in cancer supportive care should be reinforced and specific guidelines developed to help them address psychological distress of cancer survivors.

    This instrument allows controlled evaporation of the alkali metal cesium over a wide range of evaporation rates. The oven has three unique features. The first is an alkali metal reservoir that uses a dispenser as a cesium source. The heating current of the dispenser controls the evaporation rate allowing generation of an adjustable and stable flow of pure cesium. The second is a blocking valve, which is fully metallic as is the body of the oven. This construction both reduces contamination of the dispenser and enables the oven to be operated up to 300 °C, with only small temperature variations (dispenser oven can be easily transferred to the other alkali-metals.

    Entomovectoring as a plant protection strategy demands the design of an appropriate bioassay to assess the risks of potential side effects of the powder formulations in the dispenser towards the vectoring insect. This study reports on the development of a laboratory miniature-dispenser-based bioassay. This bioassay system was used to investigate the compatibility of five model products, Prestop-Mix, Signum, kaolin, wheat flour and cellulose, with the bumblebee, Bombus terrestris L. The laboratory one-way miniature-dispenser bioassay showed that the fungicides and the carrier/diluent kaolin caused a worker mortality of > 70% after 5 weeks of exposure, while worker loss with wheat flour and cellulose was no higher than in the blank control (i.e. empty miniature dispenser) (dispenser bioassay comprised separated passageways and demonstrated that only kaolin was toxic (89 ± 11%). These results were also confirmed in a flight-cage experiment. In addition, a negative effect was observed against reproduction/colony development when nests were exposed to kaolin (P dispenser and flight-cage bioassays. In the context of entomovectoring technology, the developed laboratory two-way miniature-dispenser bioassay gives a reliable prediction of the hazards associated with powder products. Additionally, the present data indicate the possibility of using cellulose and kaolin as respective negative and positive control carriers/diluents in future risk assessment experiments. Overall, the results show that, apart from kaolin, the tested fungicides and carriers/diluents are safe to be used with B. terrestris. Copyright © 2011 Society of Chemical Industry.

    Roles of the otolaryngologist and the audiologist in providing hearing health care are expanding as a result of current trends in amplification technology, legislation, and patient populations. Within clinic dispensing of hearing aids has become a part of this role expansion. Requirements for setting up a dispensary, fitting procedures, fee analysis, and statistical results of 4 1/2 years' experience are discussed. On the basis of the benefits described, direct dispensing is advocated.

    A reliable and easy to use manual dispensing system has been developed for the in meso membrane protein crystallization method. The system consists of a stepping motor-based dispenser with a new microsyringe system for dispensing, which allows us to deliver any desired volume of highly viscous lipidic mesophase in the range from ~50 to at least ~200 nl. The average, standard deviation, and coefficient of variation of 20 repeated deliveries of 50 nl cubic phase were comparable to those of a current robotic dispensing. Moreover, the bottom faces of boluses delivered to the glass crystallization plate were reproducibly circular in shape, and their centers were within about 100 μm from the center of the crystallization well. The system was useful for crystallizing membrane and soluble proteins in meso.

    In this study, a multiple sample dispenser for precisely metered fixed volumes was successfully designed, fabricated, and fully characterized on a plastic centrifugal lab-on-a-disk (LOD) for parallel biochemical single-end-point assays. The dispenser, namely, a centrifugal multiplexing fixed-volume dispenser (C-MUFID) was designed with microfluidic structures based on the theoretical modeling about a centrifugal circumferential filling flow. The designed LODs were fabricated with a polystyrene substrate through micromachining and they were thermally bonded with a flat substrate. Furthermore, six parallel metering and dispensing assays were conducted at the same fixed-volume (1.27 μl) with a relative variation of ±0.02 μl. Moreover, the samples were metered and dispensed at different sub-volumes. To visualize the metering and dispensing performances, the C-MUFID was integrated with a serpentine micromixer during parallel centrifugal mixing tests. Parallel biochemical single-end-point assays were successfully conducted on the developed LOD using a standard serum with albumin, glucose, and total protein reagents. The developed LOD could be widely applied to various biochemical single-end-point assays which require different volume ratios of the sample and reagent by controlling the design of the C-MUFID. The proposed LOD is feasible for point-of-care diagnostics because of its mass-producible structures, reliable metering/dispensing performance, and parallel biochemical single-end-point assays, which can identify numerous biochemical.

    Full Text Available Background: South Delhi is one of the well developed districts in the capital with best public health care facilities. Knowledge, attitude and dispensing practices of emergency contraceptive pills (E-pills were assessed among health care providers of government dispensaries in South Delhi. Study Design: A descriptive epidemiological study. Materials and Methods: Both medical and paramedical (n = 428 providers in 63 government health care facilities were interviewed between August to December 2007 using a semi-structured interview schedule. Results: Among the different categories of the providers, medical officers were observed to be most knowledgeable about E-pills and the pharmacists were the least. The correct prescribed dose of E-pill was known only to 32% of the providers while 49% knew about its right time of intake. Misconceptions and apprehensions for promoting its use were very much prevalent even among medical officers as majority felt that open access to E-pills would increase promiscuity. The dispensing practice of providers was found positively ( P < 0.05 correlated with their knowledge. Training resulted a significant ( P < 0.05 improvement in knowledge, attitude and dispensing practice of the providers. Knowledge and training combined together contributed 35% to the dispensing practice (R 2 = 0.35. Conclusion: Besides knowledge, behavior change communication strategies should form a part of the training curricula of health care providers that would help to improve the dispensing practice of E-pills.

    The grading of Australian junior and youth rugby union players has received substantial media attention in recent years. Media reports have focussed on size mismatches observed between players, especially players with Polynesian heritage, and the concerned parents who fear for the safety of their child owing to perceived mismatches. Although such concerns are well meaning, few media reports recognise the need for substantial evidence to determine the best grading system for junior and youth rugby union players. The current study reviewed relevant literature pertinent to the grading and dispensation of junior and youth rugby union players. Using primary and secondary search strategies, a total of 33 articles reporting the anthropometric characteristics of junior and youth rugby players were identified. Anthropometric data from the literature were compared with normative population data and currently used dispensation criteria. Junior and youth rugby players were found to be taller and heavier than normative population data. Current dispensation criteria, in terms of body mass, were found to vary and it is suggested that criteria be revised and standardised across rugby unions throughout Australia. Although it is acknowledged that other factors are important for grading players, anthropometric characteristics should be considered as potential dispensation criteria to supplement current age-based grading for junior and youth rugby union players. Measuring the body mass and stature of each junior player upon pre-season registration is suggested, which would provide data to establish valid dispensation criteria for the following season.

    Full Text Available Iron overdose remains a significant public health threat to young children. Unit dose packaging of potent iron supplements is expected to reduce the frequency of severe pediatric iron overdose incidents. Interna - tional regulations require child-resistant iron packages. We aim to know if iron is dispensed in child-resistant containers (CRCs and to emphasize the importance of using them. A prospective cross-sectional observational study assessing the proper dispensing of ferrous sulfate tablets in CRCs from major city pharmacies. Forty government and private pharmacies were visited. Ferrous sulfates with a total of 600 to 6500 mg elemental iron per package were found. The package of 6000 mg was the most commonly found. Most of the packages with high concentrations are dispensed from the government hospitals and primary healthcare centers pharmacies. None of the pharmacies dispensed iron in CRCs. To conclude, pharmacies dispensed iron in non-CRCs. Public health efforts on increasing awareness and improving packaging are highly needed. Authority regulations to use child-resistant iron packaging are required.

    Background In August 2010, a tamper-resistant formulation of controlled-release oxycodone (OxyContin-OP) was introduced in the United States but not in Canada. Our objective was to determine whether introduction of OxyContin-OP in the United States influenced prescription volumes for the original controlled-release oxycodone formulation (OxyContin) at Canadian pharmacies near the international border. Methods We conducted a population-based, serial, cross-sectional study of prescriptions dispensed from pharmacies in the 3 cities with the highest volume of US–Canada border crossings in Ontario: Niagara Falls, Windsor and Sarnia. We analyzed data on all outpatient prescriptions for OxyContin dispensed by Canadian pharmacies near each border crossing between 2010 Apr. 1 and 2012 Feb. 29. We calculated and compared monthly prescription rates, adjusted per 1000 population and stratified by tablet strength. Results The number of tablets dispensed near 4 border crossings in the 3 Canadian cities remained stable over the study period. However, the rate of dispensing at pharmacies near the Detroit–Windsor Tunnel increased roughly 4-fold between August 2010 and February 2011, from 505 to 1969 tablets per 1000 population. By April 2011, following warnings to prescribers and pharmacies regarding drug-seeking behaviour, the dispensing rate declined to 1683 tablets per 1000 population in this area. By November 2011, the rate had returned to levels observed in early 2010. Our analyses suggest that 242 075 excess OxyContin tablets were dispensed near the Detroit–Windsor Tunnel between August 2010 and October 2011. Conclusions Prescribing of the original formulation of controlled-release oxycodone rose substantially near a major international border crossing following the introduction of a tamper-resistant formulation in the United States.

    Abstract

    Liquid cell transmission electron microscopy (LCTEM) provides a unique insight into the dynamics of nanomaterials in solution. Controlling the addition of multiple solutions to the liquid cell remains a key hurdle in our ability to increase throughput and to study processes dependent on solution mixing including chemical reactions. Here, we report that a piezo dispensing technique allows for mixing of multiple solutions directly within the viewing area. This technique permits deposition of 50 pL droplets of various aqueous solutions onto the liquid cell window, before assembly of the cell in a fully controlled manner. This proof-of-concept study highlights the great potential of picoliter dispensing in combination with LCTEM for observing nanoparticle mixing in the solution phase and the creation of chemical gradients.

    Micro fluidic package with integrated reservoirs has been developed for DNA /RNA extraction application. A membrane based pump which consists of a reservoir to store reagents and a pin valve to control the fluid is developed to dispense the reagents into the chip. A programmable external actuator is fabricated to dispense the fluid from the membrane pump into the DNA chip. An elastic and high elongation thin rubber membrane is used to seal the membrane pump and at the same time prevent actuator from mixing with different reagents in the micro fluidic package. Break displacement during actuation of membrane pump sealing material is studied with different ratios of PDMS and other types of rubber materials. The fluid flow from the reservoir to the chip is controlled by a pin valve which is activated during the external actuation. A CFD simulation is performed to study the pumping action dusting the external actuation and is validated with experimental results.

  20. Clinical outcomes following the dispensing of ready-made and recycled spectacles: a systematic literature review.

    Uncorrected refractive error is the leading cause of global visual impairment. Given resource constraints in developing countries, the gold standard method of refractive error correction, custom-made spectacles, is unlikely to be available for some time. Therefore, ready-made and recycled spectacles are in wide use in the developing world. To ensure that refractive error interventions are successful, it is important that only appropriate modes of refractive error correction are used. As a basis for policy development, a systematic literature review was conducted of interventional studies analysing visual function, patient satisfaction and continued use outcomes of ready-made and recycled spectacles dispensed to individuals in developing countries with refractive errors or presbyopia. PubMed and CINAHL were searched by MESH terms and keywords related to ready-made and recycled spectacle interventions, yielding 185 non-duplicated papers. After applying exclusion criteria, eight papers describing seven studies of clinical outcomes of dispensing ready-made spectacles were retained for analysis. The two randomised controlled trials and five non-experimental studies suggest that ready-made spectacles can provide sufficient visual function for a large portion of the world's population with refractive error, including those with astigmatism and/or anisometropia. The follow-up period for many of the studies was too short to confidently comment on patient satisfaction and continued-use outcomes. No studies were found that met inclusion criteria and discussed recycled spectacles. The literature also notes concerns about quality and cost effectiveness of recycled spectacles, as well as their tendency to increase developing countries' reliance on outside sources of help. In light of the findings, the dispensing of ready-made spectacles should be favoured over the dispensing of recycled spectacles in developing countries. © 2014 The Author.

    Kistler Aerospace Corporation is building the K-1, the world's first fully reusable launch vehicle. The two-stage K- 1 is designed primarily to service the market for low-earth orbit (LEO) missions, due to Kistler's need to recover both stages. For customers requiring payload delivery to high-energy orbits, Kistler can outfit the payload with a K- 1 Active Dispenser (an expendable third stage). The K-1 second stage will deploy the Active Dispenser mated with its payload into a 200 km circular LEO parking orbit. From this orbit, the Active Dispenser would use its own propulsion to place its payload into the final desired drop-off orbit or earth-escape trajectory. This approach allows Kistler to combine the low-cost launch services offered by the reusable two-stage K-1 with the versatility of a restartable, expendable upper stage. Enhanced with an Active Dispenser, the K-1 will be capable of delivering 1,500 kg to a geosynchronous transfer orbit or up to approximately 1,000 kg into a Mars rendezvous trajectory. The list price of a K-1 Active Dispenser launch is 25 million (plus the price of mission unique integration services) significantly less than the price of any launch vehicle service in the world with comparable capability.

    Full Text Available This study presents an image-based on-line control system for a coiled pipe flocculator. A digital imaging technique developed previously is utilized to measure the characteristic floc size and a high-pressure piezo-dispenser is introduced for accurate dosing and rapid mixing of the flocculant. The controller is a conventional PI controller. Step change experiments on feed water quality, flow rate and desired floc size have been carried out for controller tuning and testing. The paper shows that the piezo-dispenser provides better flocculation results than a conventional dosing pump, and the flocculation result can be automatically controlled even when the feed water quality rapidly changes. The proposed flocculator is a simple, inexpensive and practical system for long-term laboratory tests to investigate the functionality of flocculants on varying feed waters.

    Full Text Available BACKGROUND: Combined oral contraceptive (COC use is the most commonly used reversible method of birth control. The incorrect use of COCs is frequent and one of the most common causes of unintended pregnancies. Community pharmacists (CPs are in a strategic position to improve COC use because they are the last health professional to interact with patients before drug use. OBJECTIVE: To evaluate the COC dispensing practices of CPs in a developing country. METHOD: A cross-sectional study was conducted in community pharmacies of Assis and Ourinhos microregions, Brazil, between June 1, 2012, and October 30, 2012. Four simulated patients (SPs (with counseled audio recording visited community pharmacies with a prescription for Ciclo 21(® (a COC containing ethinyl estradiol 30 mcg + levonorgestrel 15 mcg. The audio recording of every SP visit was listened to independently by 3 researchers to evaluate the COC dispensing practice. The percentage of CPs who performed a screening for safe use of COCs (i.e., taking of patients' medical and family history, and measuring of blood pressure and provided counseling, as well as the quality of the screening and counseling, were evaluated. RESULTS: Of the 185 CPs contacted, 41 (22.2% agreed to participate in the study and finished the study protocol. Only 3 CPs asked the SP a question (1 question asked by each professional, and all of the questions were closed-ended, viz., "do you smoke?" (n = 2 and "what is your age?" (n = 1. None of the CPs measured the patient's blood pressure. Six CPs provided counseling when dispensing COCs (drug dosing, 5 CPs; possible adverse effects, 2 CPs, and one CP provided counseling regarding both aspects. CONCLUSION: The CPs evaluated did not dispense COC appropriately and could influence in the occurrence of negatives therapeutic outcomes such as adverse effects and treatment failure.

    Ghrelin is a peptide hormone that has been implicated in the regulation of food intake and energy homeostasis. Ghrelin is predominantly produced in the stomach, but is also expressed in many other tissues where its functions are not well characterized. In the rodent and human pancreas, ghrelin levels peak at late gestation and gradually decline postnatally. Several studies have suggested that ghrelin regulates beta cell function during embryonic development and in the adult. In addition, in a number of mouse models, ghrelin cells appear to replace insulin and glucagon-producing cells in the islet. In this analysis, we investigated whether the absence or overexpression of ghrelin influenced the development and differentiation of the pancreatic islet during embryonic development. These studies revealed that ghrelin is dispensable for normal pancreas development during gestation. Conversely, we demonstrated that elevated ghrelin in the Nkx2.2 null islets is not responsible for the absence of insulin- and glucagon-producing cells. Finally, we have also determined that in absence of insulin, ghrelin cells form in their normal numbers and ghrelin is expressed at wild type levels. PMID:19268691

    Full Text Available Background. Continued Dispensing (CD is a new medication supply method for certain medications in Australia. It aims to prevent treatment interruption as a result of patients’ inability to obtain a new valid prescription. The only currently eligible patients for this service are statin and/or oral contraceptives users who have been using these medications for 6 months or more, have not utilized the CD method during the last 12 months, and cannot obtain an immediate appointment with the prescriber in order to get a new prescription. This study aimed to investigate patients’ attitudes towards potential extension and expansion of this medication supply method.Methods. A randomly selected 301 users of these medications from all Australian States were recruited using Computer Assisted Telephone Interview (CATI.Result. The response rate was 79%. The majority of the participants (73.3% did not agree with current restriction on CD utilization frequency. They also supported, to varying degrees, inclusion of all the proposed medications (support ranged from 44.2–78.4%. In this regard, participants who suffered from a specific disease did not differ significantly from those without the disease except in case of patients with depression (p = 0.001.Conclusions. Participants of this study strongly supported both CD extension and expansion. A future critical review of the current version of CD is highly recommended in order to enhance CD capability to achieve its goals.

    Printed electronics have been introduced into the commercial markets in recent years. Various printing technologies have emerged aiming to process printed electronic devices with low cost, environmental friendliness, and compatibility with large areas and flexible substrates. The aim of this study is to propose a continuous solution dispensing technology for processing all-printed thin-film capacitors on glass substrates using a leading-edge printing instrument. Among all printing technologies, this study provides concrete proof of the following outstanding advantages of this technology: high tolerance to inks, high throughput, low cost, and precise pattern transfers. Ag nanoparticle ink based on glycol ethers was used to print the electrodes. To obtain dielectric ink, a copolymer powder of poly(methyl methacrylate-co-benzoylphenyl methacrylate) containing crosslinkable side groups was dissolved in anisole. Various layouts were designed to support multiple electronic applications. Scanning electron microscopy and atomic force microscopy were used to investigate the all-printed capacitor layers formed using the proposed process. Additionally, the printed capacitors were electrically characterized under direct current and alternating current. The measured electrical properties of the printed capacitors were consistent with the theoretical results.

    Many factors contribute to medication nonadherence including psychological and memory disorders, aging, and pill burden. The Automated Home Medication Dispenser (AHMD) is a medication management system intended to help solve unintentional medication nonadherence. The purpose of this study was to determine if use of the AHMD improved medication adherence. We conducted a 6-month prospective, feasibility study assessing use of the AHMD in 21 patient-caregiver dyads. Patients were referred by their physician because of poor medication adherence and included if they resided in Rochester, NY and on at least two medications in pill form. Pill counts were performed at baseline to assess previous adherence. Prospective medication adherence was assessed using AHMD recorded dosing information. A paired t-test was used to compare previous and prospective adherence. The mean age of patients was 75.1 years. Fifteen patients (71.4%) and eight caregivers (38.1%) were women; half (47.6%) of caregivers lived with the patient. The most common patient comorbidities were hypertension (76.2%) and memory disorder (61.9%). Mean adherence increased from 49.0% at baseline to 96.8% after 6 months of AHMD use (p < .001). In a cohort of unintentionally nonadherent patients, use of the AHMD for 6 months significantly improved medication adherence.

    Surveillance of drug safety in pregnancy often draws on administrative prescription registries. Noncompliance in the use of prescribed medication may be frequent among pregnant women owing to their fear of fetotoxic side effects. To estimate compliance in the use of prescription drugs dispensed...... during pregnancy, we compared prescription data from the North Jutland Prescription Database with information on drug use provided by pregnant women to the Danish National Birth Cohort (DNBC), which is a health interview survey. We used the North Jutland Prescription Database to identify all prescription...... drugs dispensed during pregnancy for the 2,041 women who were enrolled in the DNBC in the County of North Jutland, Denmark. Compliance was defined as the probability of reporting drug use in DNBC after purchasing a dispensed prescription drug. The overall compliance to drugs purchased within 120 days...

    This study aimed to improve knowledge about drug administration through enteral feeding tubes (EFTs) in order to minimize efficacy and safety problems. The study was performed in a public secondary care hospital with level II accreditation by the National Accreditation Organization (Organização Nacional de Acreditação ONA), in Fortaleza, Ceará, north-eastern Brazil. One hundred and eight oral solid medications that could be administered through EFTs and were not available in liquid forms were evaluated via transformation of their solid dosage forms into liquid forms. Dispersion times and conditions were assessed to determine which medications should be crushed. We compared the use of dispensers and syringes and their connections to enteral feeding tubes and intravenous devices. Medications whose dispersion occurred within 20 minutes and could be visually perceived and whose content could be expelled without occluding the oral syringe were considered "satisfactory". The dispersion was "satisfactory" in 82 (75.9%) of the medications; they were classified as capable of being dispersed in water in the oral syringe for further administration via EFTs without the need for crushing. Use the dispenser instead of the syringe for drug administration was safer because the dispenser apparatus did not fit into equipment for intravenous drug administration.

    Automated dispensing cabinets (ADCs) are an integral component of distribution models in pharmacy departments across the country. There are significant challenges to optimizing ADC inventory management while minimizing use of labor and capital resources. The role of enhanced inventory control functionality is not fully defined. The aim of this project is to improve ADC inventory management by leveraging dynamic inventory standards and a low inventory alert platform. Two interventional groups and 1 historical control were included in the study. Each intervention group consisted of 6 ADCs that tested enhanced inventory management functionality. Interventions included dynamic inventory standards and a low inventory alert messaging system. Following separate implementation of each platform, dynamic inventory and low inventory alert systems were applied concurrently to all 12 ADCs. Outcome measures included number and duration of daily stockouts, ADC inventory turns, and number of phone calls related to stockouts received by pharmacy staff. Low inventory alerts reduced both the number and duration of stockouts. Dynamic inventory standards reduced the number of daily stockouts without changing the inventory turns and duration of stockouts. No change was observed in number of calls related to stockouts made to pharmacy staff. Low inventory alerts and dynamic inventory standards are feasible mechanisms to help optimize ADC inventory management while minimizing labor and capital resources.

    Full Text Available Eva Blozik,1,2 Roland Rapold,1 Oliver Reich1 1Department of Health Sciences, Helsana Group, Zürich, Switzerland; 2Department of Medicine, Division of General Practice, University Medical Centre Freiburg, Freiburg, Germany Background: Drugs can be supplied either directly from the prescribing physician (physician dispensing [PD] or via a pharmacy. It is unclear whether the dispensing channel is associated with quality problems. Potentially inappropriate medication (PIM is associated with adverse outcomes in older persons and can be considered a marker for quality deficits in prescribing. We investigated whether prevalence of PIM differs across dispensing channels. Patients and methods: We analyzed basic health insurance claims of 50,747 person quarter years with PIM use of residents of the Swiss cantons Aargau and Lucerne of the years 2012 and 2013. PIM was identified using the Beers 2012 criteria and the PRISCUS list. We calculated PIM prevalence stratified by supply channel. Adjusted mixed effects logistic regression analysis was done to estimate the effect of obtaining medications through the dispensing physician as compared to the pharmacy channel on receipt of PIM. The most frequent PIMs were identified. Results: There is a small but detectable difference in total PIM prevalence: 30.7% of the population supplied by a dispensing physician as opposed to 29.3% individuals who received medication in a pharmacy. According to adjusted logistic regression individuals who obtained the majority of their medications from their prescribing physician had a 15% higher chance to receive a PIM (odds ratio 1.15, 95% confidence interval 1.08–1.22; P<0.001. Conclusion: Physician dispensing seems to affect quality and safety of drug prescriptions. Quality issues should not be neglected in the political discussion about the regulations on PD. Future studies should explore whether PD is related to other indicators of inefficiency or quality flaws. The present

    A high performance liquid chromatography-photodiode array detector (HPLC-PDA) fingerprinting and ultra high performance liquid chromatography-photodiode array detector coupled with quadrupole time-of-flight mass spectrometry (UHPLC-PDA-QTOF-MS/MS) based chemical profiling approach was developed to rapidly find characteristic chemical markers for quality control of dispensing granules, taking Chuanxiong Rhizoma (CR) as a model herb. Firstly, CR crude drugs, their traditional decoctions and CR dispensing granules were analyzed by HPLC-PDA to rapidly establish the fingerprints and thereby generate the simulative median chromatograms of CR crude drugs, decoctions and dispensing granules, and by comparing the simulative median chromatograms, major characteristic peaks of CR decoctions and dispensing granules could be determined. Secondary, UHPLC-PDA-QTOF-MS/MS was used to identify the major characteristic peaks of CR decoctions and dispensing granules. The identities of three major peaks were elucidated and confirmed to be ferulic acid (1), senkyunolide I (2) and senkyunolide H (3) by comparing the mass/UV spectra and retention times with that of the reference compounds. Thirdly, an HPLC-PDA method was validated to quantify the three characteristic components in commercial CR dispensing granules. The average contents of ferulic acid and senkyunolide H were found to be less than 1.0mg/g, whereas that of senkyunolide I was 4.40mg/g in CR dispensing granules, which indicated that senkyunolide I might be chosen as a suitable quantitative marker, while ferulic acid and senkyunolide H as qualitative markers for the quality evaluation of CR dispensing granules. It is suggested that this newly established approach could be used to practically and rapidly find suitable marker compounds for quality control of dispensing granules derived from other medicinal herbs.

    2012-01-01

    We propose a smart medication dispenser having a high degree of scalability and remote manageability. We construct the dispenser to have extensible hardware architecture for achieving scalability, and we install an agent program in it for achieving remote manageability. The dispenser operates as follows: when the real-time clock reaches the predetermined medication time and the user presses the dispense button at that time, the predetermined medication is dispensed from the medication dispensing tray (MDT). In the proposed dispenser, the medication for each patient is stored in an MDT. One smart medication dispenser contains mainly one MDT; however, the dispenser can be extended to include more MDTs in order to support multiple users using one dispenser. For remote management, the proposed dispenser transmits the medication status and the system configurations to the monitoring server. In the case of a specific event such as a shortage of medication, memory overload, software error, or non-adherence, the event is transmitted immediately. All these operations are performed automatically without the intervention of patients, through the agent program installed in the dispenser. Results of implementation and verification show that the proposed dispenser operates normally and performs the management operations from the medication monitoring server suitably.

    Full Text Available In Romania, direct sales of raw milk to the final consumer is developed based on the local regulations. These are in accordance to European Regulation that must meet some quality requirements for the total number of germs, somatic cells, without antibiotics, coming from healthy animals who did not suffer from diseases that can be transmitted to humans through milk. Raw milk is sold in Romania in local markets and by automatic milk dispenser machines. Based on these regulations, a study regarding the quality and security to human health of raw milk was conducted on the commercialized milk in local markets and automatic milk dispensers. During May-June 2014 samples of raw milk were collected from Cluj-Napoca local markets and automatic milk dispensers. All samples were kept to refrigeration conditions until the moment of analyze which took place at the sampling day. The following parameters were taken into account: fat content, protein, casein, lactose, nonfat dry matter, pH, milk freezing point, added water, antibiotics residues, milk urea, number of germ cells and somatic cells. All obtained results were verified by the validated methods applied. Our research can be forward conducted in order to verify the hygiene and composition of milk from the whole dairy chain.

    Full Text Available Abstract Background In the present study, chemical consistency between traditional and dispensing granule decoctions of Tao-Hong-Si-Wu decoction was rapidly evaluated by UPLC-QTOF-MS coupled with the MarkerLynx software. Two different kinds of decoctions, namely traditional decoction: water extract of mixed six constituent herbs of Tao-Hong-Si-Wu decoction, and dispensing granules decoction: mixed water extract of each individual herbs of Tao-Hong-Si-Wu decoction, were prepared. Results Chemical difference was found between traditional and dispensing granule decoctions, and albiflorin, paeoniflorin, gallic acid, amygdalin, and hydroxysafflor yellow A were identified as the significantly changed components during decocting Tao-Hong-Si-Wu decoction. All the peaks of mass spectrum from Tao-Hong-Si-Wu decoction and each herb were extracted and integration by using QuanLynx™. And the optimized data was used for linear regression analysis. The contribution of each herb in Tao-Hong-Si-Wu decoction, and the optimal compatibility proportion of dispensing granule decoction were derived from the linear regression equation. Conclusions The optimal dosage proportionality of Tao-Hong-Si-Wu dispensing granule decoction was obtained as 2.5:0.2:1:0.5:0.6:0.1 (DG : CX : BS : SD : TR : HH, which guided better clinic application of Tao-Hong-Si-Wu decoction as dispensing granule decoctions usage, and it also provided some experimental data to reveal the compatibility rule of the relative TCM formulae.

  19. Refusals by pharmacists to dispense emergency contraception: a critique.

    Science.gov (United States)

    Wall, L Lewis; Brown, Douglas

    2006-05-01

    Over the past several months, numerous instances have been reported in the United States media of pharmacists refusing to fill prescriptions written for emergency postcoital contraceptives. These pharmacists have asserted a "professional right of conscience" not to participate in what they interpret as an immoral act. In this commentary, we examine this assertion and conclude that it is not justifiable, for the following reasons: 1) postcoital contraception does not interfere with an implanted pregnancy and, therefore, does not cause an abortion; 2) because pharmacists do not control the therapeutic decision to prescribe medication but only exercise supervisory control over its dispensation, they do not possess the "professional right" to refuse to fill a legitimate prescription; 3) even if one were to grant pharmacists the "professional right" not to dispense prescriptions based on their own personal values and opinions, pharmacists "at the counter" lack the fundamental prerequisites necessary for making clinically sound ethical decisions, that is, they do not have access to the patient's complete medical background or the patient's own ethical preferences, have not discussed relevant quality-of-life issues with the patient, and do not understand the context in which the patient's clinical problem is occurring. We conclude that a policy that allows pharmacists to dispense or not dispense medications to patients on the basis of their personal values and opinions is inimical to the public welfare and should not be permitted.

  10. Type I IFN Signaling Is Dispensable during Secondary Viral Infection.

    Directory of Open Access Journals (Sweden)

    Martin P Hosking

    2016-08-01

    Full Text Available Innate immune responses in general, and type I interferons (T1IFNs in particular, play an important and often essential role during primary viral infections, by directly combatting the virus and by maximizing the primary adaptive immune response. Several studies have suggested that T1IFNs also contribute very substantially to the secondary (recall response; they are thought (i to be required to drive the early attrition of memory T cells, (ii to support the subsequent expansion of surviving virus-specific memory cells, and (iii to assist in the suppression and clearance of the infectious agent. However, many of these observations were predicated upon models in which T1IFN signaling was interrupted prior to a primary immune response, raising the possibility that the resulting memory cells might be intrinsically abnormal. We have directly addressed this by using an inducible-Cre model system in which the host remains genetically-intact during the primary response to infection, and in which T1IFN signaling can be effectively ablated prior to secondary viral challenge. We report that, in stark contrast to primary infection, T1IFN signaling is not required during the recall response. IFNαβR-deficient memory CD8+ and CD4+ memory T cells undergo attrition and expansion with kinetics that are indistinguishable from those of receptor-sufficient cells. Moreover, even in the absence of functional T1IFN signaling, the host's immune capacity to rapidly suppress, and then to eradicate, a secondary infection remains intact. Thus, this study shows that T1IFN signaling is dispensable during the recall response to a virus infection. Moreover, two broader implications may be drawn. First, a T cell's requirement for a cytokine is highly dependent on the cell's maturation / differentiation status. Consequently, second, these data underscore the importance of evaluating a gene's impact by modulating its expression or function in a temporally-controllable manner.

    A non-dispensing pharmacist conducts clinical pharmacy services aimed at optimizing patients individual pharmacotherapy. Embedding a non-dispensing pharmacist in primary care practice enables collaboration, probably enhancing patient care. The degree of integration of non-dispensing pharmacists into multidisciplinary health care teams varies strongly between settings. The degree of integration may be a determinant for its success. This study investigates how the degree of integration of a non-dispensing pharmacist impacts medication related health outcomes in primary care. In this literature review we searched two electronic databases and the reference list of published literature reviews for studies about clinical pharmacy services performed by non-dispensing pharmacists physically co-located in primary care practice. We assessed the degree of integration via key dimensions of integration based on the conceptual framework of Walshe and Smith. We included English language studies of any design that had a control group or baseline comparison published from 1966 to June 2016. Descriptive statistics were used to correlate the degree of integration to health outcomes. The analysis was stratified for disease-specific and patient-centered clinical pharmacy services. Eighty-nine health outcomes in 60 comparative studies contributed to the analysis. The accumulated evidence from these studies shows no impact of the degree of integration of non-dispensing pharmacists on health outcomes. For disease specific clinical pharmacy services the percentage of improved health outcomes for none, partial and fully integrated NDPs is respectively 75%, 63% and 59%. For patient-centered clinical pharmacy services the percentage of improved health outcomes for none, partial and fully integrated NDPs is respectively 55%, 57% and 70%. Full integration adds value to patient-centered clinical pharmacy services, but not to disease-specific clinical pharmacy services. To obtain maximum benefits

    This study is to quantitatively evaluate the efficacy of using a non-contact automatic articulating paper dispenser for reducing microbial articulating paper contamination. Articulating papers in four-handed mode, non-four-handed mode, and via an automatic articulating paper dispenser were evaluated. An adenosine triphosphate bioluminescence assay was used to quantitatively measure the relative light unit (RLU) values of the rest unused articulating papers in the same package to detect contamination at 4 time points, and triplicate examinations were performed for all three methods. The RLUs were recorded, compared, and evaluated. For four-handed mode (n = 36), the RLUs at the four time points were 2.44, 32.89, 37.89, and 27.22, with a satisfactory rate of 94%. The RLUs for non-four-handed mode (n = 36) were 2.22, 286.44, 299.44, and 493.56, with a satisfactory rate of 36%. The RLUs for using the automatic dispenser (n = 36) were all 0 with a satisfactory rate of 100%. The satisfactory rates were significantly different among three methods. No significant differences were observed in the satisfactory rates for the four time points samples. Contact by gloved hands can cause severe biological contamination of articulating paper. However, by using standard four-handed mode or a non-contact automatic articulating paper dispenser, contamination can be controlled.

    Full Text Available The use of thalidomide was never discontinued in Brazil where it is prescribed for leprosy type 2 reaction. Babies with birth defects compatible with the thalidomide embryopathy phenotype were born after 1965, an indication that control on drug dispensing and use failed in the country. The article reports data on thalidomide dispensing and clinical uses in the Federal District in 2011/12, when new rules were put into effect, and data on drug dispensing and use obtained ten years earlier. It was found that the number of patients making use of thalidomide declined from 819 in 2001 to 369 in 2011/12. Leprosy accounted for over 70% of prescriptions in both time periods analyzed in this study. In the same time interval, however, use for lupus erythematosus decreased from 13.7 to 4.9%, while that for multiple myeloma increased from 2.9 to 20.3% of all prescriptions. Thalidomide prescription for the remaining approved indications was far less frequent, and so was the use for off label indications that accounted for <1% of prescriptions in 2001 and 2011/12. Registration of prescribing doctors, patients and dispensing units at the state department of health, apparently rendered this control more effective and reliable.

  14. Failure to Use Cubicles and Concentrate Dispenser by Heifers after Transfer from Rearing Accommodation to Milking Herd

    Full Text Available Thirty-three dairy farms in the Norwegian counties of Østfold and Akershus in which cubicle sheds had been in use for at least one year and with a herd size of less than 60 cows, were contacted and asked to participate in a study. The study focused on heifers' use of cubicles and concentrate dispenser just after being transferred from rearing accommodation to the milking herd. For each heifer, the farmer recorded cubicle use once nightly between 9 and 11 pm. The daily amount of concentrate released in the dispenser and the allotted daily ration were also recorded. The recording period was 15 consecutive days for cubicle use and 7 days for concentrate dispenser use. Cubicle refusal behaviour, i.e. lying outside the cubicles, was analysed by logistic regression using rearing accommodation of heifers, herd size, heifer age, and housing layout as independent variables, and herd as a clustering variable. On Day 2 after transfer, 34% of the heifers were showing cubicle refusal behaviour (N = 340. By Day 15 this percentage had dropped to 23. Cubicle refusal was lower throughout the whole period among heifers which used the cubicles on the 3 first days after transfer compared to those which did not. This tendency could also be detected several months later. The analysis showed cubicle refusal to be significantly associated with rearing accommodation (OR = 6.1, c.i.95%OR = 1.5–24.3, P = 0.01 and cubicle layout in the shed (OR = 0.2, c.i.95%OR = 0.0–0.7, P = 0.01. None of the tested variables were found to be significant for failure to use the concentrate dispenser, a behaviour which was less frequent than cubicle refusal. However, 8 percent of the heifers did not visit the dispenser at all throughout the 7 days of observation.

    Hand-applied dispensers are successfully used in mating disruption programs, but cost of labor to apply these dispensers limits their adoption. Creating hand-applied dispensers that release larger amounts of pheromone and that can be applied at lower densities per hectare could reduce the cost of mating disruption and increase its use. The effect of reducing the number of point sources per hectare while keeping the amount of pheromone applied per hectare constant on the success of Grapholita molesta (Busck) (Lepidoptera: Tortricidae) mating disruption was investigated with Confuse-OFM, paraffin disk, and Isomate-M Rosso dispensers. For all dispensers, as point source density decreased, numbers of moths captured increased, percentage of orientation disruption to traps decreased, and variability in these measures increased. Decreasing point source density, even while keeping the amount of pheromone applied per hectare constant is not a viable option for reducing the cost of G. molesta mating disruption with hand-applied dispensers. Puffers (aerosol dispensers) are applied at 2.5-5 dispensers per ha for G. molesta control. However, hand-applied dispensers fail when clumped at such low numbers of release sites. Potential explanations for the success of Puffers and the failure of hand-applied dispensers at very low point source densities are presented. The utility of paraffin disk dispensers as experimental devices also is discussed.

    A piezoelectric dispenser has been fabricated based on the idea of a piezoelectric-metal-cavity (PMC) actuator. The PMC actuator consists of a metal ring sandwiched between two identical piezoelectric unimorphs. The radial contraction of the piezoelectric ceramic is converted into a flextensional motion of the unimorph, causing a large flexural displacement in the center part of the actuator. With the PMC actuator as a fluid chamber, the large flexural actuation can be used to produce the displacement needed to eject fluid. By applying an appropriate voltage to the piezoelectric unimorphs, a drop-on-demand ejection of ink or water can be achieved. The efficiency of fluid ejection can be enhanced after installing a valve in the fluid chamber. With the simple PMC structure, the dispenser can be operated with a low driving voltage of 12-15 V.

    Photoinjector performance is a limiting factor in the continued development of high powered FELs and electron beam-based accelerators. Presently available photocathodes are plagued with limited efficiency and short lifetime in an RF-gun environment, due to contamination or evaporation of a photosensitive surface layer. An ideal photocathode should have high efficiency at long wavelengths, long lifetime in practical vacuum environments, and prompt emission. Cathodes with high efficiency typically have limited lifetime, and vice versa, and the needs of the photocathode are generally at odds with those of the drive laser. A potential solution is the low work function dispenser cathode, where lifetime issues are overcome by periodic in situ regeneration that restores the photosensitive surface layer, analogous to those used in the microwave power tube industry. This work reports on the fabrication techniques and performance of cesiated metal photocathodes and cesiated dispenser cathodes, with a focus on understan...

    Plan sponsors encourage the use of mail order pharmacies because they believe mail order dispensing will lower their prescription drug costs. Health plans and pharmacy benefit management companies (PBMs) usually offer patients substantially lower copayments to incentivize them to use mail order pharmacies. A number of health plans and PBMs now require patients to use these pharmacies for maintenance prescriptions. To (a) compare costs for prescriptions dispensed through mail order and retail pharmacies in Medicare Part D plans and (b) examine whether mail order or retail pharmacies provided lower all third-party costs for each of the top 300 products; the relationship between whether a product was available generically and whether mail order or retail pharmacies provided lower prices; and the generic substitution rates at mail order and retail pharmacies. The sample for this study consisted of 2010 Medicare Part D prescription drug data for the 300 products with the highest sales at mail order pharmacies. The prescriptions included in the study were dispensed in the initial coverage limit phase of Part D by retail or mail order pharmacies to patients who were insured by Part D for 12 months in 2010, who received no Part D subsidies, and who were alive for the full year in 2010. Mean-per-unit costs were calculated for both mail order and retail prescriptions for each of the top 300 products. Products were defined by Medi-Span Generic Product Indentifier. Summary statistics for the overall costs of mail order and retail prescriptions were calculated as the weighted mean-per-unit costs of the top 300 products. The weighting factor for both mail order and retail prescriptions included both the mail order quantity dispensed per prescription and the number of prescriptions dispensed. Weighting both mail and retail prescriptions by mail order quantities dispensed and numbers of prescriptions ensured that the results reflected actual cost differences rather than

    Full Text Available We describe an automated robotic technique called direct-dispense to fabricate a polymeric platform that supports optical sensor arrays. Direct-dispense, which is a type of the emerging direct-write microfabrication techniques, uses fugitive organic inks in combination with cross-linkable polymers to create microfluidic channels and other microstructures. Specifically, we describe an application of direct-dispensing to develop optical biochemical sensors by fabricating planar ridge waveguides that support sol-gelderived xerogel-based thin films. The xerogel-based sensor materials act as host media to house luminophore biochemical recognition elements. As a prototype implementation, we demonstrate gaseous oxygen (O2 responsive optical sensors that operate on the basis of monitoring luminescence intensity signals. The optical sensor employs a Light Emitting Diode (LED excitation source and a standard silicon photodiode as the detector. The sensor operates over the full scale (0%-100% of O2 concentrations with a response time of less than 1 second. This work has implications for the development of miniaturized multisensor platforms that can be cost-effectively and reliably mass-produced.

  1. Control of microbial contamination in drinking water from microfiltering dispensers by dialysis ultrafilters

    Full Text Available Tap water filtering devices are widely employed to improve odor and taste of tap water, or to obtain refrigerated or sparkling drinking water. The presence of disinfectants-resistant bacteria in tap water is responsible of the biofilm formation inside tubes and tanks. The consequent contamination of dispensed water is a well-known hygiene problem because of the quite constant presence of potentially pathogenic bacteria likes P. aeruginosa. In this study, we tested the technical feasibility and effectiveness of the addition to different commercial devices of a packaged polysulphone fibers filter. We aimed to find a simple solution to implement the quality of the delivered water. Water contamination levels were determined in a wide selection of microfiltered water dispensers and we selected among them a representative group of 10 devices, new or in use. The packaged ultrafilter was introduced in about half of them, to monitor, when possible, in parallel the contamination levels and flow rate of a couple of identical units, with and without the filter. The placement of the dialysis filters resulted feasible at different positions along the water circuits of the variously designed filtration units. Delivered water resulted completely free from bacteria when the filter was placed exactly at, or very close to, the outlet in spite of the inner surfaces contamination. This performance was not obtained in presence of a more or less long tract of water circuits downstream the ultrafilter: a significant but not complete reduction of the plate count numbers was observed. The filters worked in continue over the whole study period, ten months, showing exactly the same efficiency. Moreover, the flow rate in presence of the filter was quite unaffected. The addition of this kind of filter to already in use water dispensers was technically easy, and its use can be recommended in all cases a simple but reliable water sanitization is requested.

    This study presents a ring-type micro-structure design on the substrate and its corresponding micro fabrication processes for a lens-type light-emitting diode (LED) package. The dome-type or crater-type silicone lenses are achieved by a dispensing and embossing process rather than a molding process. Silicone with a high viscosity and thixotropy index is used as the encapsulant material. The ring-type micro structure is adopted to confine the dispensed silicone encapsulant so as to form the packaged lens. With the architecture and process described, this LED package technology herein has three merits: (1) the flexibility of lens-type LED package designs is enhanced; (2) a dome-type package design is used to enhance the intensity; (3) a crater-type package design is used to enhance the view angle. Measurement results show the ratio between the lens height and lens radius can vary from 0.4 to 1 by changing the volume of dispensed silicone. The view angles of dome-type and crater-type packages can reach 155° ± 5° and 175° ± 5°, respectively. As compared with the commercial plastic leaded chip carrier-type package, the luminous flux of a monochromatic blue light LED is improved by 15% by the dome-type package (improved by 7% by the crater-type package) and the luminous flux of a white light LED is improved by 25% by the dome-type package (improved by 13% by the crater-type package). The luminous flux of monochromatic blue light LED and white light LED are respectively improved by 8% and 12% by the dome-type package as compare with the crater-type package.

    Medication errors (MEs) are important in terms of their magnitude and severity, and there are numerous systems in place to reduce their occurrence. However, the ideal system has not yet been identified. The authors' institution uses three different medication prescription-dispensation systems which operate simultaneously. ME rates were compared, overall and by phase (prescription, transcription and administration) and their overall and specific clinical impact. The administration of medicinal products was observed directly and compared with medical and nursing prescriptions. Errors and adverse events were classified by a consensus of experts. In the traditional system the error prevalence rate was 13.59 per cent, (99 per cent CI, 12.15-14.61 per cent), in the single dose system it was 6.43 per cent (99 per cent CI, 5.53-7.32) and in the electronic prescription system it was 8.86 per cent (99 per cent CI, 7.33-10.17). The highest error rates in all phases were found in the traditional system. The phase affected by most errors in all three models was transcription, and the least affected was administration, except for the single dose system, in which prescription was the worst. The effects of errors in the administration phase are greater, although less so than with the automated system. The dispensation phase was not analyzed. A study of errors will enable us to reduce their occurrence if we know the most frequent types and in which phase they are produced, we will be able to prioritise the areas in which to work and select the necessary preventive measures. It is possible that automated medication dispensation systems reduce error rates and the severity of their effects.

    Full Text Available People in many low-income countries access medicines from retail drug shops. In Tanzania, a public-private partnership launched in 2003 used an accreditation approach to improve access to quality medicines and pharmaceutical services in underserved areas. The government scaled up the accredited drug dispensing outlet (ADDO program nationally, with over 9,000 shops now accredited. This study assessed the relationships between community members and their sources of health care and medicines, particularly antimicrobials, with a specific focus on the role ADDOs play in the health care system.Using mixed methods, we collected data in four regions. We surveyed 1,185 households and audited 96 ADDOs and 84 public/nongovernmental health facilities using a list of 17 tracer drugs. To determine practices in health facilities, we interviewed 1,365 exiting patients. To assess dispensing practices, mystery shoppers visited 306 ADDOs presenting one of three scenarios (102 each about a child's respiratory symptoms.Of 614 household members with a recent acute illness, 73% sought outside care-30% at a public facility and 31% at an ADDO. However, people bought medicines more often at ADDOs no matter who recommended the treatment; of the 581 medicines that people had received, 49% came from an ADDO. Although health facilities and ADDOs had similar availability of antimicrobials, ADDOs had more pediatric formulations available (p<0.001. The common perception was that drugs from ADDOs are more expensive, but the difference in the median cost to treat pneumonia was relatively minimal (US$0.26 in a public facility and US$0.30 in an ADDO. Over 20% of households said they had someone with a chronic condition, with 93% taking medication, but ADDOs are allowed to sell very few chronic care-related medicines. ADDO dispensers are trained to refer complicated cases to a health facility, and notably, 99% of mystery shoppers presenting a pneumonia scenario received an

    Neurocan is a component of the extracellular matrix in brain. Due to its inhibition of neuronal adhesion and outgrowth in vitro and its expression pattern in vivo it was suggested to play an important role in axon guidance and neurite growth. To study the role of neurocan in brain development we ...... appear largely normal. Mild deficits in synaptic plasticity may exist, as maintenance of late-phase hippocampal long-term potentiation is reduced.

    Full Text Available Antibiotics are drugs widely used in prophylaxis and treatment of a great number of diseases. However, their use must be carefully controlled as acquisition in pharmacies, often without medical prescription, is elevated. The role of pharmacists in these circumstances is to practice dispensation in a rational manner. Through a structured questionnaire with open and closed questions, this study investigated the profile of antibiotics dispensed in pharmacies of Tubarão, Santa Catarina, Brazil. From the responses, it was observed that 85.0% dispense this class of medicine without medical prescription, mainly for treatment of respiratory (62.8% and urinary (12.0% tract disorders. Moreover, pharmacists' guidance was largely focused on posology (66.6% and drug interaction (12.6%, in addition to the interactions with contraceptives, alcohol and milk. The importance of avoiding antibiotics dispensation without medical prescription must be emphasized, as well as the benefits of educating the population to promote the rational use of medicines.Antibióticos são fármacos amplamente utilizados na profilaxia e no tratamento de grande número de doenças.

    The Student Counselling Service at the Faculty of Health Sciences, Aarhus University, Denmark, has experienced an increase in medical students with poor mental well-being. This was a descriptive, retrospective survey of 1,056 medical students commencing their studies in the period from September 2003 to February 2006. The study had a four-year follow-up period. Demographics, delay, discontinuation and dispensations were determined. Each application was reviewed and the reasons why each student applied were recorded. Applicants were significantly older than non-applicants. 90.9% of the dispensations were related to first-year examinations (50 students). A significantly higher number of dispensation applicants (58.2%) discontinued their studies (32 students) compared with dispensation non-applicants. 54.6% of the applicants (30 students) did not pass their first-year examinations. The study time was delayed by more than two years among 67.3% of the applicants (37 students). 27.3% of the applicants were students with a foreign qualifying exam (15 students). Females listed mainly emotional reasons in their applications. Such reasons included, among others, depression, stress and anxiety. In contrast, males listed study- and family-related issues. Focused student counselling is recommended for all students of medicine, especially in the first year of their studies. Furthermore, lessons aiming to build study skills and teach students how to cope with study-related stress and exam-related anxiety are recommended. Particular attention should be given to foreign students. Each applicant should be advised individually. not relevant. not relevant.

    2003-01-01

    A method and apparatus for dispensing fluid from a drop-on-demand (DOD) fluid dispenser. The method involves withdrawing fluid in the dispenser for a first duration of time, followed by a second duration of time during which the fluid is propelled toward the orifice of the dispenser. Following the period during which the fluid is propelled, there is a second withdrawing of the fluid into the dispenser. The duration of the propelling period is shorter than the duration of either the first withdrawing or the second withdrawing. The propelling of the fluid results in the extension of a small tongue of fluid from the meniscus of the fluid. The second withdrawing of the fluid results in a retraction of the meniscus into the passageway such that only the small tongue of fluid separates and is ejected from the dispenser.

    Full Text Available Abstract Background A scarcity of human resources for health has been identified as one of the primary constraints to the scale-up of the provision of Anti-Retroviral Treatment (ART. In South Africa there is a particularly severe lack of pharmacists. The study aims to compare two task-shifting approaches to the dispensing of ART: Indirectly Supervised Pharmacist’s Assistants (ISPA and Nurse-based pharmaceutical care models against the standard of care which involves a pharmacist dispensing ART. Methods A cross-sectional mixed methods study design was used. Patient exit interviews, time and motion studies, expert interviews and staff costs were used to conduct a costing from the societal perspective. Six facilities were sampled in the Western Cape province of South Africa, and 230 patient interviews conducted. Results The ISPA model was found to be the least costly task-shifting pharmaceutical model. However, patients preferred receiving medication from the nurse. This related to a fear of stigma and being identified by virtue of receiving ART at the pharmacy. Conclusions While these models are not mutually exclusive, and a variety of pharmaceutical care models will be necessary for scale up, it is useful to consider the impact of implementing these models on the provider, patient access to treatment and difficulties in implementation.

    Crack cocaine use increases risky sexual behavior and HIV exposure; therefore, safe sexual practices should be encouraged during cocaine addiction treatment. Research indicates that placing condom dispensers in private restrooms increases taking free condoms. We investigated two other dispenser locations (a day room vs. counselors' offices) and found that substantially more condoms were taken when dispensers were in the day room. This is an important issue for public health facilities without private restrooms. PMID:16795876

    To determine the effect of installing an original-pack automated dispensing system (ADS) on dispensary workload and prevented dispensing incidents in a hospital pharmacy. Data on dispensary workload and prevented dispensing incidents, defined as dispensing errors detected and reported before medication had left the pharmacy, were collected over 6 weeks at a National Health Service hospital in Wales before and after the installation of an ADS. Workload was measured by non-participant observation using the event recording technique. Prevented dispensing incidents were self-reported by pharmacy staff on standardised forms. Median workloads (measured as items dispensed/person/hour) were compared using Mann-Whitney U tests and rate of prevented dispensing incidents were compared using Chi-square test. Spearman's rank correlation was used to examine the association between workload and prevented dispensing incidents. A P value of ≤0.05 was considered statistically significant. Median dispensary workload was significantly lower pre-automation (9.20 items/person/h) compared to post-automation (13.17 items/person/h, P automation (0.28%) than pre-automation (0.64%, P automation (ρ = 0.23, P automation improves dispensing efficiency and reduces the rate of prevented dispensing incidents. It is proposed that prevented dispensing incidents frequently occurred during periods of high workload due to involuntary automaticity. Prevented dispensing incidents occurring after a busy period were attributed to staff experiencing fatigue after-effects. © 2012 The Authors. IJPP © 2012 Royal Pharmaceutical Society.

    In the second half of 2010, abuse-deterrent extended-release oxycodone hydrochloride (OxyContin; Purdue Pharma) was introduced and propoxyphene was withdrawn from the US market. The effect of these pharmaceutical market changes on opioid dispensing and overdose rates is unknown. To evaluate the association between 2 temporally proximate changes in the opioid market and opioid dispensing and overdose rates. Claims from a large national US health insurer were analyzed, using an interrupted time series study design. Participants included an open cohort of 31.3 million commercially insured members aged 18 to 64 years between January 1, 2003, and December 31, 2012, with median follow-up of 20 months (last follow-up, December 31, 2012). Introduction of abuse-deterrent OxyContin (resistant to crushing or dissolving) on August 9, 2010, and market withdrawal of propoxyphene on November 19, 2010. Standardized opioid dispensing rates and prescription opioid and heroin overdose rates were the primary outcomes. We used segmented regression to analyze changes in outcomes from 30 quarters before to 8 quarters after the 2 interventions. Two years after the opioid market changes, total opioid dispensing decreased by 19% from the expected rate (absolute change, -32.2 mg morphine-equivalent dose per member per quarter [95% CI, -38.1 to -26.3]). By opioid subtype, the absolute change in dispensing by milligrams of morphine-equivalent dose per member per quarter at 2 years was -11.3 (95% CI, -12.4 to -10.1) for extended-release oxycodone, 3.26 (95% CI, 1.40 to 5.12) for other long-acting opioids, -8.19 (95% CI, -9.30 to -7.08) for propoxyphene, and -16.2 (95% CI, -18.8 to -13.5) for other immediate-release opioids. Two years after the market changes, the estimated overdose rate attributed to prescription opioids decreased by 20% (absolute change, -1.10 per 100,000 members per quarter [95% CI, -1.47 to -0.74]), but heroin overdose increased by 23% (absolute change, 0.26 per 100

    Background and Objective Pseudomonas aeruginosa infection represents a main cause of morbidity and mortality among immunocompromised patients. This study describes a fatal epidemic of P. aeruginosa that occurred in a hematology unit in Italy. Methods Retrospective cohort study, prospective surveillance, auditing, extensive testing on healthcare workers and environmental investigation were performed to define the dynamics and potential causes of transmission. RAPD, macrorestriction analyses and sequence typing were used to define relationships between P. aeruginosa isolates. Results Eighteen cases of infection were identified in the different phases of the investigation. Of these, five constitute a significant molecular cluster of infection. A P. aeruginosa strain with the same genetic fingerprint and sequence type (ST175) as clinical isolates strain was also isolated from a heavily contaminated triclosan soap dispenser. Discussion and Conclusions Our results are consistent with the hypothesis that patients became indirectly infected, e.g., during central venous catheter handling through contaminated items, and that the triclosan soap dispenser acted as a common continuous source of P. aeruginosa infection. Since P. aeruginosa is intrinsically unsusceptible to triclosan, the use of triclosan-based disinfectant formulations should be avoided in those healthcare settings hosting patients at high risk of P. aeruginosa infection.

    To investigate the influence of container structures and content solutions on the time of dispensing from eye dropper bottles. Eye dropper bottle models, solution models (filtrate water/surfactant solution) and a dispensing time measuring apparatus were prepared to measure the dispensing time. With filtrate water and pressure thrust load of 0.3 MPa, the dispensing time significantly increased from 1.1 +/- 0.5 seconds to 4.6 +/- 1.1 seconds depending on the decrease of inner aperture diameters from 0.4 mm to 0.2 mm (P bottle models with inner aperture diameters of 0.4 mm or larger, the dispensing time became constant. The dispensing time using surfactant solution showed the same tendency as above. When pressure thrust load was large (0.07 MPa), the solution flew out continuously with inner aperture diameters of 0.4 mm or larger and the dispensing time could not be measured. The inner aperture diameter most strongly explained the variation of the dispensing time in both the content solutions in the multiple linear regression analysis (filtrate water: 46%, R(2) = 0.462, surfactant solution: 56%, R(2) = 0.563). Among content solutions and container structures, the dispensing time was mostly influenced by the diameter of the inner aperture of bottles.

  1. Automatic Control System for Dispensing Precise Amounts of FInely Divided Solids

    A device for automatic dispensing of precise amounts of finely divided solids has been developed. Precision is a function of dispensing time. Smaller than gram quantities may be dispensed at a rate of about 1/3 g/min with a precision corresponding to a weight range of about 0.001 g for a series. The process consists in moving the material with the effect of the vibratory motion of a miniature air-powered vibrator. Operation is automatically controlled by the electronic system of the weighing unit interfaced to the pneumatic dispensing device via a combination fluidic and pneumatic control system.

    To assess the compliance of community pharmacies with the regulations that prohibit the dispensing of prescription-only medications in the absence of a physician prescription in Saudi Arabia. A cross-sectional study was conducted in the period between October 2014 and January 2015. A list of 10 prescription-only medications were selected to be studied. 150 community pharmacies were visited across 6 major regions in Saudi Arabia to assess the prevalence of non-compliance among community pharmacies. Pharmacies were selected in random and researchers (disguised as patients) requested to purchase prescription-only medications in the absence of a prescription. Not all medications were purchased at once. Data were recorded per pharmacy, where pharmacies that approved dispense of the selected drug were scored as non-compliant and the pharmacies that rejected dispense of the selected drug were scored as compliant. Compliance rate was calculated per region per drug. Pharmacies based in governmental hospitals were visited in parallel. A total of 20 were visited. Data and statistical analysis were performed using Statistical Analyses Software (SAS 9.3). A total of 150 pharmacies were visited over a period of 3 months. On average, the percent approved dispense of prescription-only drugs across 6 regions in Saudi Arabia is 63% and the percent rejected dispense is 37% representing a significant non-compliance rate regarding the selected list of medications in this study. The frequency of dispense per medication across 6 major regions in Saudi Arabia is as follows: Isosorbide dinitrate (86%), Enoxaparin (82%), nitroglycerin (74%), Propranolol (73%), Verapamil (70%), Warfarin (65%), Methyldopa (64%), Ciprofloxacin (57%) and Codeine (4%). Non-compliance of community pharmacies with the law of pharmaceutical practice is at an alarming rate in the Kingdom of Saudi Arabia and authoritative figures must intervene to impede and combat such activities .

    To describe recent trends in opioid prescribing and prescription opioid poisoning resulting in hospitalisation or death in Victoria, Australia. This is a population-based ecological study of residents of Victoria, 2006 - 14. Australian Bureau of Statistics residential population data were combined with Pharmaceutical Benefits Scheme (PBS) opioid prescription data, Victorian Admitted Episodes Data (VAED) and cause of death data. Annual opioid dispensings increased by 78% in 2006 - 13, from 0.33 to 0.58 per population. Opioid use increased with age: in 2013, 14% of Victorian residents aged ≥65 years filled at least one oxycodone prescription. In 2006 - 14, prescription opioid related hospital admissions increased by 6.8% per year, from 107 to 187 /1,000,000 person-years; 56% were due to intentional self-poisoning. Annual deaths increased from 21 to 28 /1,000,000 persons, in 2007 - 11. Admissions and deaths peaked at 25-44 years. Although both opioid prescribing and poisoning have increased, there is discrepancy between the exposed group (dispensings increased with age) and those with adverse consequences (rates peaked at ages 25-44 years). A better understanding is needed of drivers of prescribing and adverse consequences. Together with monitoring of prescribing and poisoning, this will facilitate early detection and prevention of a public health problem. © 2016 The Authors.

    Assessment of synergistic effects of drug combinations in vitro is a critical part of anticancer drug research. However, the complexities of dosing and analyzing two drugs over the appropriate range of doses have generally led to compromises in experimental design that restrict the quality and robustness of the data. In particular, the use of a single dose response of combined drugs, rather than a full two-way matrix of varying doses, has predominated in higher-throughput studies. Acoustic dispensing unlocks the potential of high-throughput dose matrix analysis. We have developed acoustic dispensing protocols that enable compound synergy assays in a 384-well format. This experimental design is considerably more efficient and flexible with respect to time, reagent usage, and labware than is achievable using traditional serial-dilution approaches. Data analysis tools integrated in Genedata Screener were used to efficiently deconvolute the combination compound mapping scheme and calculate compound potency and synergy metrics. We have applied this workflow to evaluate interactions among drugs targeting different nodes of the mitogen-activated protein kinase pathway in a panel of cancer cell lines. © 2015 Society for Laboratory Automation and Screening.

    The experimental results of studies of four kinds of cathode emitting intense electron beams are demonstrated under multi-pulsed mode based on an experimental setup including two multi-pulse high voltage sources. The tested cathodes include velvet, carbon fibers, carbon nano-tubes (CNTs) and dispenser cathodes. The results indicate that all four are able to emit multi-pulsed beams. For velvet, carbon fiber and CNTs, the electron induced cathode plasma emission may be the main process and this means that there are differences in beam parameters from pulse to pulse. For dispenser cathodes tested in the experiment, although there is a little difference from pulse to pulse for some reason, thermal-electric field emission may be the main process.

    Private pharmacies are the first line of health care in many communities, commonly selling antibiotics in small doses and prescription-only drugs such as steroids without medical supervision. The aim was to study the effectiveness of a multi-faceted intervention on the dispensing practices of drug sellers in Hanoi and Bangkok. The study was a randomized, controlled trial with 68 Hanoi and 78 Bangkok pharmacies, randomly selected and assigned for intervention and control. Behaviour was assessed by five simulated client visits per pharmacy per dispensing practice, at baseline and a month or more after each intervention. Three three-month interventions were implemented sequentially with four months in between: enforcement of regulations with local inspectors visiting to emphasize the importance of prescription-only medicine legislation; education, performed face-to-face in Hanoi and by a large group in Bangkok; and peer review, voluntary in Bangkok and compulsory in Hanoi. The intervention resulted in significant improvements in Hanoi, reducing the dispensing of illegal steroids (29% vs. 62%) and low dose antibiotics (69% vs. 90%), sustained by means of the peer review (17% vs. 57% steroids and 71% vs. 95% antibiotics), and in fewer dispensers asking no questions and giving no advice (11% vs. 30% steroids and 51% vs. 81% antibiotics). The only significant improvement in Bangkok was the reduction in illegally dispensing steroids (25% vs. 44%) after the regulatory intervention. In Bangkok, fewer of those in the group who volunteered for the peer review asked no questions and gave no advice for low-dose antibiotics requests after the peer review (58% vs. 81%). A multi-component intervention can have a profound effect in changing dispensers' behaviour, but the effect is dependant on the context and the method of implementation. Possible reasons for differences are discussed.

    The genomes of many filamentous fungi consist of a 'core' part containing conserved genes essential for normal development as well as conditionally dispensable (CD) or lineage-specific (LS) chromosomes. In the plant-pathogenic fungus Fusarium oxysporum f. sp. lycopersici, one LS chromosome harbours effector genes that contribute to pathogenicity. We employed flow cytometry to select for events of spontaneous (partial) loss of either the two smallest LS chromosomes or two different core chromosomes. We determined the rate of spontaneous loss of the 'effector' LS chromosome in vitro at around 1 in 35 000 spores. In addition, a viable strain was obtained lacking chromosome 12, which is considered to be a part of the core genome. We also isolated strains carrying approximately 1-Mb deletions in the LS chromosomes and in the dispensable core chromosome. The large core chromosome 1 was never observed to sustain deletions over 200 kb. Whole-genome sequencing revealed that some of the sites at which the deletions occurred were the same in several independent strains obtained for the two chromosomes tested, indicating the existence of deletion hotspots. For the core chromosome, this deletion hotspot was the site of insertion of the marker used to select for loss events. Loss of the core chromosome did not affect pathogenicity, whereas loss of the effector chromosome led to a complete loss of pathogenicity. © 2016 THE AUTHORS.

    Full Text Available Lakes are one of most important freshwater ecosystems, playing significant role in functioning of nature and human economy. Swarzędzkie Lake is good example of ecosystem, which in last half-century was exposed to the influence of strong anthropopressure. Direct inflow of sewage with large number of biogens coming to the lake with water of inflows caused distinct disturbance of its functioning. In autumn 2011 restoration begined on Swarzędzkie Lake for reduction of lake trophy and improvement of water quality. For achieving better and quicker effect, simultaneously combination of some methods was applied, among others method of oxygenation of over-bottom water with help of pulverization aerator and method of precise inactivation of phosphorus in water depths. Characterization and analysis of improved coagulant dispenser applying active substance only during work of pulverization aerator is the aim of this thesis. Principle of dispenser work, its structure and location in pulverization aerator were explained. It was stated, that introduction to water a factor initiating process of phosphorus inactivation causes significant reduction of mineral phosphorus in water and size of coagulant dose correlates with intensity of work of pulverization aerator with wind drive.

    To assess pharmacists' willingness to initiate the dispensing of naloxone. As of 2015, Kentucky law permits certified pharmacists to dispense naloxone under a physician-approved protocol. Electronic survey (e-mail) gauging perception of pharmacists' role in opioid overdose and attitudes toward, and barriers to, naloxone dispensing. All Kentucky pharmacists with active licenses in 2015. Ordinal logistic regression was used to estimate the impact of pharmacist characteristics and attitudes on willingness to initiate naloxone dispensing, where the dependent variable was operationalized as a Likert-type question on a scale of 1 (not at all willing) to 6 (very willing). Of 4699 practicing Kentucky pharmacists, 1282 responded, of which 834 were community practitioners (response rate 27.3%). Pharmacists reported varying willingness to initiate naloxone dispensing, with 37.3% very willing (score 5 or 6) and 27.9% not willing (score 1 or 2). However, a majority of pharmacists reported willingness to dispense naloxone with a valid prescription (54.0%, score 5 or 6). Women pharmacists were 1.3 times more likely than men to be willing to initiate naloxone dispensing (95% confidence interval [CI] 1.0-1.6). Those who reported confidence in identifying individuals at risk for overdose were 1.2 times more likely to initiate dispensing, and those who reported confidence in ability to educate patients about overdose were 1.6 times more likely to express willingness to initiate naloxone dispensing (95% CIs, respectively, 1.0-1.3 and 1.4-1.8). Community pharmacists reported barriers to naloxone access at higher rates than pharmacists from other practice settings. Kentucky pharmacists are divided in their willingness to initiate naloxone dispensing; however, those who are confident in their ability to identify overdose risks are more willing. Increasing pharmacist confidence through appropriately designed education programs could facilitate pharmacist participation in naloxone

    To examine qualitative and quantitative levels and trends of prescription opioid analgesics ("opioids") use and the potential impact of prescription monitoring programs (PMPs), in the 10 Canadian provinces, for 2005-2010. Opioid dispensing data from a representative sample of 2700 retail pharmacies were obtained. Individual opioid dispensing values were translated into defined daily doses per day/1000 population and categorized into "weak opioids" and "strong opioids" by standardized methods. Opioid prescription rates between provinces and over time, as well as the impact of PMPs, were examined using regression analyses techniques (i.e., Poisson, ANOVAs). Significant differences between provinces in the overall standardized rates of dispensing for total opioids, as well as for "weak opioids" and "strong opioids" categories, were found. The majority of provinces featured increases or curvilinear trends in the standardized amounts of opioids dispensed over time, mainly driven by increases in "strong opioids" use. In addition, significant inter-provincial differences in the levels of dispensing of individual opioids were found. Comparisons of changes in opioid dispensing between provinces with and without PMPs did not indicate significant differences. Opioid use featured significant quantitative and qualitative differences between provinces in Canada and showed an overall increasing trend mainly driven by changes in "strong opioids" in the study period. Reasons for the observed differences are not clear yet require systematic examination to allow evidence-based interventions in the interest of equitable pain treatment as well as the reduction of high levels of opioid-related morbidity and mortality in Canada.

    Handling and dosing of cells comprise the most critical step in the microfabrication of cell-based assay systems for screening and toxicity testing. Therefore, the immediate drop-on-demand technology (I-DOT) was developed to provide a flexible noncontact liquid handling system enabling dispensing of cells and liquid without the risk of cross-contamination down to a precise volume in the nanoliter range. Liquid is dispensed from a source plate within nozzles at the bottom by a short compressed air pulse that is given through a quick release valve into the well, thus exceeding the capillary pressure in the nozzle. Droplets of a defined volume can be spotted directly onto microplates or other cell culture devices. We present a study on the performance and biological impact of this technology by applying the cell line MCF-7, human fibroblasts, and human mesenchymal stem cells (hMSCs). For all cell types tested, viability after dispensing is comparable to the control and exhibits similar proliferation rates in the absence of apoptotic cells, and the differentiation potential of hMSCs is not impaired. The immediate drop-on-demand technology enables accurate cell dosage and offers promising potential for single-cell applications. © 2014 Society for Laboratory Automation and Screening.

    We describe gravimetric methods for measuring the mass of droplets generated by a drop-on-demand (DOD) microdispenser. Droplets are deposited, either continuously at a known frequency or as a burst of known number, into a cylinder positioned on a submicrogram balance. Mass measurements are acquired precisely by computer, and results are corrected for evaporation. Capabilities are demonstrated using isobutyl alcohol droplets. For ejection rates greater than 100 Hz, the repeatability of droplet mass measurements was 0.2%, while the combined relative standard uncertainty (u(c)) was 0.9%. When bursts of droplets were dispensed, the limit of quantitation was 72 microg (1490 droplets) with u(c) = 1.0%. Individual droplet size in a burst was evaluated by high-speed videography. Diameters were consistent from the tenth droplet onward, and the mass of an individual droplet was best estimated by the average droplet mass with a combined uncertainty of about 1%. Diameters of the first several droplets were anomalous, but their contribution was accounted for when dispensing bursts. Above the limits of quantitation, the gravimetric methods provided statistically equivalent results and permit detailed study of operational factors that influence droplet mass during dispensing, including the development of reliable microassays and standard materials using DOD technologies.

    Stepwise preparation of calibration standards and quality controls (QCs) is one of the most routine and laborious steps in bioanalysis. An alternative non-contact dispenser using low picoliter digitized dispensing technology is evaluated for its application in non-stepwise preparation of calibration curve and QCs in bioanalysis. Fluorescein was initially used to assess the accuracy and precision of dispense volumes with fluorescent measurement. Various concentrations of MX-1, an in-house proprietary small molecule compound, in neat solution and in dog plasma were prepared manually with calibrated pipettors and digitally by the digital dispenser. The plasma samples were extracted by protein precipitation. The resultant extracted samples and neat solutions of MX-1 were analyzed by liquid chromatography/tandem mass spectrometry (LC/MS/MS) using an electrospray ionization (ESI) source in positive ion mode with selected reaction monitoring (SRM) of the mass transitions. In the three-day precision and accuracy assessment of dispensing volumes between 13 pL to 411.2 nL, the intra-day precision and accuracy ranged from 1.4% to 10.3% and -12.7% to 12.8%, respectively. The inter-day precision and accuracy ranged from 3.5% to 7.8% and -6.6% to 10.4%, respectively. For real analysis of in vivo study samples, all 49 samples analyzed showed a less than 5% difference between calibrations with digital and manual curve preparations. The resultant pharmacokinetic (PK) parameters were physiologically comparable as well. Using the digitized picoliter dispensing technology, high-speed automated precise and accurate dispense of a wide range of volumes can be achieved and tests for bioanalytical standards and QC preparations passed the stringent criteria set forth for regulated bioanalysis using LC/MS/MS-based technology. The digital dispenser has been found to be a useful tool in drug discovery for automatically preparing standards and QCs in seconds with low consumption of stock

  20. Spill-Resistant Alkali-Metal-Vapor Dispenser

    Klipstein, William

    2005-01-01

    A spill-resistant vessel has been developed for dispensing an alkali-metal vapor. Vapors of alkali metals (most commonly, cesium or rubidium, both of which melt at temperatures slightly above room temperature) are needed for atomic frequency standards, experiments in spectroscopy, and experiments in laser cooling. Although the present spill-resistant alkali-metal dispenser was originally intended for use in the low-gravity environment of outer space, it can also be used in normal Earth gravitation: indeed, its utility as a vapor source was confirmed by use of cesium in a ground apparatus. The vessel is made of copper. It consists of an assembly of cylinders and flanges, shown in the figure. The uppermost cylinder is a fill tube. Initially, the vessel is evacuated, the alkali metal charge is distilled into the bottom of the vessel, and then the fill tube is pinched closed to form a vacuum seal. The innermost cylinder serves as the outlet for the vapor, yet prevents spilling by protruding above the surface of the alkali metal, no matter which way or how far the vessel is tilted. In the event (unlikely in normal Earth gravitation) that any drops of molten alkali metal have been shaken loose by vibration and are floating freely, a mesh cap on top of the inner cylinder prevents the drops from drifting out with the vapor. Liquid containment of the equivalent of 1.2 grams of cesium was confirmed for all orientations with rubbing alcohol in one of the prototypes later used with cesium.

    Marrian, C. R. K.; Haas, G. A.; Shih, A.

    The problems associated with the reactivation following shelf storage of different types of tungsten-based dispenser cathodes have been investigated. Reactivation times were found to be severely limited by repoisoning processes, which have been isolated and identified. Data are presented, indicating the finite times (in the absence of repoisoning), which are required to reactivate the cathodes following exposure to various gases. Of the gases studied, exposure to oxygen and water vapour caused the slowest reactivations. Water vapour was the component of the vacuum system ambient responsible for the poisoning caused by exposure to the ambient. Following exposure to each of the gases studied, the "M" type cathode reactivated slower than the "B" type cathode. The results have shown that both the choice of cathode and the design of the microwave tube are important if a fast turn-on following shelf storage is to be achieved.

    Hand hygiene is one of the most important measures to prevent transmission of infectious agents and plays a major role in prevention of infection in any type of healthcare setting. While requirements for the efficacy of hand disinfectants are defined in European testing norms such as the EN 1500 for hygienic hand disinfection or EN 12791 for surgical hand preparation, no specific recommendations for hand rub dispensers and liquid soap dispensers have been given yet. Therefore, the intention of the present recommendation on soap and hand rub dispensers in healthcare facilities is to close this gap and to enhance future improvement of dispenser functionality and design. Regardless of manufacture and design of a hand rub or liquid soap dispensers the following requirements shall be met in healthcare facilities:Triggering the dispenser must be possible without using hands. Sensor- or elbow-operated dispensers both fulfill this requirement. Dispensers must be only refillable in a modality where the content, be it a hand rub or liquid soap, cannot be contaminated. This is achieved best by using replaceable cartridge systems. Refilling through "top-up" must not be possible. The disperser should allow usage of different types of cartridges made by different manufacturers. Dispensers must be operated and maintained such that a microbial contamination of the pump nozzle may easily be avoided. It must be possible to identify the products used in a dispenser easily and without any manipulation. Identifying the type of product, be it a hand rub or a liquid soap, as well as reading the product's name and critical manufacturers' warnings must be possible at any time. The disperser must allow identification of the level of the used product without any further manipulation at any time. The design of the dispenser must allow easy cleaning and disinfection the outside and inside of the dispenser. The manufacturer of the dispenser must provide the user with information on applicable

    Full Text Available Purpose: Automation of pharmacy workflow can reduce medication errors as well as improve efficiency of the medication picking, packing and labeling process. Since September 2012, two drug dispensing systems (DDS began operations in the Singapore General Hospital Specialist Outpatient Clinic Pharmacy. This study sought to evaluate the impact of the DDS on safety and efficiency in the pharmacy. Methods: The primary outcome was the rate of prevented dispensing incidents contributed by DDS or manual picking of medications defined as the number of prevented dispensing incidents per 1000 medications picked. The secondary outcome was the productivity of each full time equivalent (FTE when assigned to either the DDS or manual picking stations. Data pertaining to the primary and secondary outcomes between January and December 2013 were collected and analyzed. The rate of prevented dispensing incidents was expressed in median (interquartile range and compared using Mann-Whitney U test. Other continuous variables were expressed in mean ± standard deviation and compared using independent samples t-test. Results: An average of 59494 medications was picked every month in the pharmacy. DDS accounted for 21.1 percent while manual picking accounted for 78.9 percent of all the medications picked. The median rate of prevented dispensing incidents per month committed by manual picking (2.73 was significantly higher than the DDS (0.00. DDS had greater productivity with each FTE in the DDS having an average of 6175 picks per month which was significantly higher than each FTE in the manual picking stations which had an average of 4867 picks per month. Conclusion: Installation of DDS in an outpatient pharmacy improved safety of the pharmacy workflow by automating the medication picking, packing and labeling process and minimizing human errors. Efficiency of the medication picking, packing and labeling process was also improved by the DDS as there were continuous

    To assess the efficacy of a new quality control strategy based on daily randomised sampling and monitoring a Sentinel Surveillance System (SSS) medication cart, in order to identify medication errors and their origin at different levels of the process. Prospective quality control study with one year follow-up. A SSS medication cart was randomly selected once a week and double-checked before dispensing medication. Medication errors were recorded before it was taken to the relevant hospital ward. Information concerning complaints after receiving medication and 24-hour monitoring were also noted. Type and origin error data were assessed by a Unit Dose Quality Control Group, which proposed relevant improvement measures. Thirty-four SSS carts were assessed, including 5130 medication lines and 9952 dispensed doses, corresponding to 753 patients. Ninety erroneous lines (1.8%) and 142 mistaken doses (1.4%) were identified at the Pharmacy Department. The most frequent error was dose duplication (38%) and its main cause inappropriate management and forgetfulness (69%). Fifty medication complaints (6.6% of patients) were mainly due to new treatment at admission (52%), and 41 (0.8% of all medication lines), did not completely match the prescription (0.6% lines) as recorded by the Pharmacy Department. Thirty-seven (4.9% of patients) medication complaints due to changes at admission and 32 matching errors (0.6% medication lines) were recorded. The main cause also was inappropriate management and forgetfulness (24%). The simultaneous recording of incidences due to complaints and new medication coincided in 33.3%. In addition, 433 (4.3%) of dispensed doses were returned to the Pharmacy Department. After the Unit Dose Quality Control Group conducted their feedback analysis, 64 improvement measures for Pharmacy Department nurses, 37 for pharmacists, and 24 for the hospital ward were introduced. The SSS programme has proven to be useful as a quality control strategy to identify Unit

    In this cross-sectional study, data were collected from responses to a questionnaire on dispensing frequencies of antimicrobials used by dairy practitioners in Ontario in dairy cattle in 2001. Data were validated through clinical case scenarios. Respondents reported using antimicrobials across all categories of importance to human medicine (medically important, Categories I to III) with a diversity of treatment combinations and routes of administration. Respondents anticipated that a request for direct veterinary supervision by producers was dependent on case severity, highlighting the importance of on-farm diagnostic and treatment protocols. Knowledge of the antimicrobials used in lactating cow therapy, and their frequency and reasons for use, will provide baseline information and contribute to antimicrobial stewardship in this food-animal production sector.

    Smart textiles require flexible electronics that can withstand daily stresses like bends and stretches. Printing using conductive inks provides the flexibility required but the current printing techniques suffered from ink incompatibility, limited of substrates to be printed with and incompatible with conformal substrates due to its rigidity and low flexibility. An alternate printing technique via automatic fluid dispensing system is proposed and its performances on printing strain gauge on conformal substrates were evaluated to determine its feasibility. Process parameters studied including printing speed, deposition height, curing time and curing temperature. It was found that the strain gauge is proven functional as expected since different strains were induced when bent on variation of bending angles and curvature radiuses from designated bending fixtures. The average change of resistances were doubled before the strain gauge starts to break. Printed strain gauges also exhibited some excellence elasticity as they were able to resist bending up to 70° angle and 3 mm of curvature radius.

    Summary The cadherin family of cell adhesion molecules mediates adhesive interactions that are required for the formation and maintenance of tissues. Previously, we demonstrated that N-cadherin, which is required for numerous morphogenetic processes, is expressed in the pancreatic epithelium at E9.5, but later becomes restricted to endocrine aggregates in mice. To study the role of N-cadherin during pancreas formation and function we generated a tissue specific knockout of N-cadherin in the early pancreatic epithelium by inter-crossing N-cadherin-floxed mice with Pdx1Cre mice. Analysis of pancreas-specific ablation of N-cadherin demonstrates that N-cadherin is dispensable for pancreatic development, but required for β-cell granule turnover. The number of insulin secretory granules is significantly reduced in N-cadherin-deficient β-cells, and as a consequence insulin secretion is decreased. PMID:20533404

    Neuraminidase inhibitor (NI) dispensing has emerged as a possible automated data source for influenza surveillance. We aimed to evaluate its timeliness, correlation, and predictive accuracy in relation to influenza activity in Quebec, Canada, 2010-2013. Our secondary objective was to use the same metrics to compare NI dispensing to visits for influenza-like illness (ILI) in emergency departments (EDs). Provincial weekly counts of positive influenza laboratory tests were used as a reference measure for the level of influenza circulation. We applied ARIMA models to account for serial correlation. We computed cross-correlations to measure the strengths of association and lead-lag relationships between NI dispensing, ILI ED visits, and our reference indicator. Finally, using an ARIMA model, we evaluated the ability of NI dispensing and ILI ED visits to predict laboratory-confirmed influenza. NI dispensing was significantly correlated (R = 0·68) with influenza activity with no lag. The maximal correlation of ILI ED visits was not as strong (R = 0·50). Both NI dispensing and ILI ED visits were significant predictors of laboratory-confirmed influenza in a multivariable model; predictive potential was greatest when NI counts were lagged to precede laboratory surveillance by 2 weeks. We conclude that NI dispensing data provides timely and valuable information for influenza surveillance.

    parameters, they hold considerable promise for future pest control against a variety of pest insects. In combination with well known synthetic sex pheromones, they can be used for communication disruption studies. One example, the pheromone of the European grape vine moth Lobesia botrana (Lepidoptera: Tortricidae), in combination with Ecoflex fibers, has been thoroughly tested in vineyards of Freiburg, Southwest Germany, with promising results. Seven weeks of communication disruption have been achieved, long enough to cover any one of several flights of this multivoltine grape pest. Disruption effects of around 95% have been achieved which are statistically indistinguishable from positive controls tested simultaneously with Isonet LE fibers, while an untreated negative control is significantly different. Ecoflex is a cheap organic co-polyester and completely biodegradable within half a year. Thus, an extra recovery step as with some other dispensers is unnecessary. This co-polyester is also of proven non-toxicity. The extension of the seven week disruption period towards half a year (the entire duration of all 3 Lobesia flights combined) is desirable and is under additional investigation in the near future. The discovery of suitable mesofibers is protected by European and US patents. The pheromone literature appearing between 1959 and today contains more than 25,000 references. This wealth of information is immediately applicable to pest management. It has major impacts on chemical ecology and IPM. In this paper, an attempt is made to compare the systems described in the literature and to derive some predictions about their prospective innovation potential. Special emphasis is given to the new development of organic biodegradable microfibers. To this end, a new electronic searching algorithm is introduced for reviewing the entries to be found in 4 specific databases. Its prominent features will be described. Surprisingly we found no previous entries in the literature linking

    Full Text Available OBJECTIVE: To evaluate the costs and patient safety of a pilot implementation of an automated dispensing cabinet in a critical care unit of a private tertiary hospital in São Paulo/Brazil. METHODS: This study considered pre- (January-August 2013 and post- (October 2013-October 2014 intervention periods. We considered the time and cost of personnel, number of adverse events, audit adjustments to patient bills, and urgent requests and returns of medications to the central pharmacy. Costs were evaluated based on a 5-year analytical horizon and are reported in Brazilian Reals (R$ and US dollars (USD. RESULTS: The observed decrease in the mean number of events reported with regard to the automated drug-dispensing system between pre- and post-implementation periods was not significant. Importantly, the numbers are small, which limits the power of the mean comparative analysis between the two periods. A reduction in work time was observed among the nurses and administrative assistants, whereas pharmacist assistants showed an increased work load that resulted in an overall 6.5 hours of work saved/day and a reduction of R$ 33,598 (USD 14,444 during the first year. The initial investment (R$ 206,065; USD 88,592 would have been paid off in 5 years considering only personnel savings. Other findings included significant reductions of audit adjustments to patient hospital bills and urgent requests and returns of medications to the central pharmacy. CONCLUSIONS: Evidence of the positive impact of this technology on personnel time and costs and on other outcomes of interest is important for decision making by health managers.

  12. Piwi genes are dispensable for normal hematopoiesis in mice.

    Directory of Open Access Journals (Sweden)

    Mona J Nolde

    Full Text Available Hematopoietic stem cells (HSC must engage in a life-long balance between self-renewal and differentiation to sustain hematopoiesis. The highly conserved PIWI protein family regulates proliferative states of stem cells and their progeny in diverse organisms. A Human piwi gene (for clarity, the non-italicized "piwi" refers to the gene subfamily, HIWI (PIWIL1, is expressed in CD34⁺ stem/progenitor cells and transient expression of HIWI in a human leukemia cell line drastically reduces cell proliferation, implying the potential function of these proteins in hematopoiesis. Here, we report that one of the three piwi genes in mice, Miwi2 (Piwil4, is expressed in primitive hematopoetic cell types within the bone marrow. Mice with a global deletion of all three piwi genes, Miwi, Mili, and Miwi2, are able to maintain long-term hematopoiesis with no observable effect on the homeostatic HSC compartment in adult mice. The PIWI-deficient hematopoetic cells are capable of normal lineage reconstitution after competitive transplantation. We further show that the three piwi genes are dispensable during hematopoietic recovery after myeloablative stress by 5-FU. Collectively, our data suggest that the function of the piwi gene subfamily is not required for normal adult hematopoiesis.

    In this work, a novel droplet microfluidic sample introduction system for inductively coupled plasma mass spectrometry (ICPMS) is proposed and characterized. The cheap and disposable microfluidic chip generates droplets of an aqueous sample in a stream of perfluorohexane (PFH), which is also used to eject them as a liquid jet. The aqueous droplets remain intact during the ejection and can be transported into the ICP with >50% efficiency. The transport is realized via a custom-built system, which includes a membrane desolvator necessary for the PFH vapor removal. The introduction system presented here can generate highly monodisperse droplets in the size range of 40-60 μm at frequencies from 90 to 300 Hz. These droplets produced very stable signals with a relative standard deviation (RSD) comparable to the one achieved with a commercial droplet dispenser. Using the current system, samples with a total volume of <1 μL can be analyzed. Moreover, the capabilities of the setup for introduction and quantitative elemental analysis of single cells were described using a test system of bovine red blood cells. In the future, other modules of the modern microfludics can be integrated in the chip, such as on-chip sample pretreatment or parallel introduction of different samples.

    A process to pattern slots approximately 1.25 microns in width into 25-micron-thick W films that have been deposited onto flat or concave surfaces is discussed. A 25-micron-thick W film with a high degree of (100) orientation is chemically vapor deposited (CVD) onto a flat or concave Mo mandrel. A 5-micron-thick Al film is deposited onto the CVD W, followed by 2 microns of photoresist. On concave cathodes, XeCl2 laser ablation or X-ray lithography is used to pattern the photoresist, whereas on flat cathodes deep UV lithography can be used. The patterned photoresist serves as the mask in a Cl ion-beam-assisted etching (IBAE) process to pattern the Al. An alternative process is to deposit Al2O3 films onto the W and pattern the Al2O3 using laser ablation. The W film is then patterned to 3-6-micron slot widths using IBAE + ClF3 with the patterned Al or Al2O3 as the mask. Finally, a sputter deposition step is required to close up the slots to approximately 1 micron. The process described is capable of patterning concave dispenser cathodes to a controlled and precise porosity.

    Degradation models for multilure fruit fly trap dispensers were analyzed to determine their potential for use in large California detection programs. Solid three-component male lure TMR (trimedlure [TML], methyl eugenol [ME], raspberry ketone [RK]) dispensers impregnated with DDVP (2, 2-dichlorovinyl dimethyl phosphate) insecticide placed inside Jackson traps were weathered during summer (8 wk) and winter (12 wk) in five citrus-growing areas. Additionally, TMR wafers without DDVP, but with an insecticidal strip, were compared to TMR dispensers with DDVP. Weathered dispensers were sampled weekly and chemically analyzed. Percent loss of TML, the male lure for Ceratitis capitata (Wiedemann) Mediterranean fruit fly; ME, the male lure for Bactrocera dorsalis (Hendel), oriental fruit fly; RK, the male lure for Bactrocera cucurbitae (Coquillett), melon fly; and DDVP was measured. Based on regression analyses for the male lures, TML degraded the fastest followed by ME. Degradation of the more chemically stable RK was discontinuous, did not fit a regression model, but followed similar seasonal patterns. There were few location differences for all three male lures and DDVP. Dispensers degraded faster during summer than winter. An asymptotic regression model provided a good fit for % loss (ME, TML, and DDVP) for summer data. Degradation of DDVP in TMR dispensers was similar to degradation of DDVP in insecticidal strips. Based on these chemical analyses and prior bioassay results with wild flies, TMR dispensers could potentially be used in place of three individual male lure traps, reducing costs of fruit fly survey programs. Use of an insecticidal tape would not require TMR dispensers without DDVP to be registered with US-EPA. Published by Oxford University Press on behalf of Entomological Society of America 2017.

    Automated protocols for measuring and dispensing solutions containing radioisotopes are essential not only for providing a safe environment for radiation workers but also to ensure accuracy of dispensed radioactivity and an efficient workflow. For this purpose, we have designed ARAS, an automated radioactivity aliquoting system for dispensing solutions containing positron-emitting radioisotopes with particular focus on fluorine-18 ((18)F). The key to the system is the combination of a radiation detector measuring radioactivity concentration, in line with a peristaltic pump dispensing known volumes. The combined system demonstrates volume variation to be within 5 % for dispensing volumes of 20 μL or greater. When considering volumes of 20 μL or greater, the delivered radioactivity is in agreement with the requested amount as measured independently with a dose calibrator to within 2 % on average. The integration of the detector and pump in an in-line system leads to a flexible and compact approach that can accurately dispense solutions containing radioactivity concentrations ranging from the high values typical of [(18)F]fluoride directly produced from a cyclotron (~0.1-1 mCi μL(-1)) to the low values typical of batches of [(18)F]fluoride-labeled radiotracers intended for preclinical mouse scans (~1-10 μCi μL(-1)).

    A 3-axis dispensing system is utilized to control the initiating and terminating fiber positions and trajectory via the dispensing software. The polymer fiber length and orientation is defined by the spatial positioning of the dispensing system 3-axis stages. The fiber diameter is defined by the prescribed dispense time of the dispensing system valve, the feed rate (the speed at which the stage traverses from an initiating to a terminating position), the gauge diameter of the dispensing tip, the viscosity and surface tension of the polymer solution, and the programmed drawing length. The stage feed rate affects the polymer solution's evaporation rate and capillary breakup of the filaments. The dispensing system consists of a pneumatic valve controller, a droplet-dispensing valve and a dispensing tip. Characterization of the direct write process to determine the optimum combination of factors leads to repeatedly acquiring the desired range of fiber diameters. The advantage of this robotic dispensing system is the ease of obtaining a precise range of micron/sub-micron fibers onto a desired, programmed location via automated process control. Here, the discussed self-assembled micron/sub-micron scale 3D structures have been employed to fabricate suspended structures to create micron/sub-micron fluidic devices and bioengineered scaffolds.

    The effect of varying the height of reservoir dispensers for mating disruption of codling moth, Cydia pomonella (L.), was investigated. The goal was to improve the effectiveness of C. pomonella mating disruption through improved understanding of adult distribution within the tree canopy and the impact of pheromone dispenser placement on disruption. Two dispensers per tree were placed at 2 m and 4 m and/or one dispenser at each height on the tree at a label rate of 1000 units ha(-1) . Monitoring traps and tethered female moths were deployed in plots at 2 and 4 m heights to assess treatment effects by catches or matings respectively. Fewest male moths were captured with all dispensers placed at 4 m. Female mating was lowest, and with least variation between females tethered at 2 and 4 m, when dispensers were placed simultaneously at 2 and 4 m (28% mated). Mating was 32% with both dispensers at 4 m, 38% with both dispensers at 2 m and 46% in the no disruption control. Mating was highest across treatments when females were tethered at 2 m and dispensers placed at 4 m (40%), and when females were tethered at 4 m with dispensers placed at 2 m (46%). Traps at 4 m in trees captured more male moths than traps at 2 m, regardless of disruption dispenser positioning. Female mating was lowest when dispensers were placed simultaneously at 2 and 4 m, suggesting that current recommendations for placement of reservoir dispensers in tree crowns may be suboptimal.

    Full Text Available The Law Commission of India in its 222nd report emphasized the need for Alternative Disputes Resolution (ADR for the dispensation of justice, because the courts are inaccessible owing to various factors, e.g., poverty, social and political backwardness, illiteracy, ignorance, procedural formalities and inordinate delay in judgments. During the ancient period the disputes were resolved in an informal manner by neutral third persons or people’s court in villages and it continued till the middle of the 20th century. Unfortunately, after the Independence of India in 1947, this system was dissuaded and the government permitted to continue the adversarial system of justice. In 1980, a committee was set up. It recommended Lok Adalats (People’s Courts. In 1987, the Legal Services Authorities Act was enacted. This Act obligates the states to provide free legal aid to poor persons. Besides this, the Act provides for the establishment of permanent Lok Adalats.This is one of the important modes of ADR. Lok Adalats have been established in all the districts of the country. They bring conciliatory settlement in complicated cases arising out of matrimonial, landlord-tenants, property, insurance and commercial disputes. There are four methods of ADR, viz., negotiation, mediation, conciliation and arbitration. Mediation and arbitration are widely preferred. They are alternatives to litigation. The Arbitration Act for the first time was enacted in 1889 and it was subsequently amended many times. On the objections raised by the Supreme Court of India and also on the adoption of UNCITRAL Model Law on International Commercial Arbitration, in 1996 Arbitration and Conciliation Act was enacted. This law is almost the same as is almost in all the countries.Further, the Government of India established International Centre for Alternative Disputes Resolution (CADR with the objectives of promotion, propagation, and popularizing the settlement of domestic and

    Full Text Available The back bombardment (BB effect limits wide usage of thermionic rf guns. The BB effect induces not only ramping-up of a cathode’s temperature and beam current, but also degradation of cavity voltage and beam energy during a macropulse. This paper presents a comparison of the BB effect for the case of dispenser tungsten-base (DC and lanthanum hexaboride (LaB_{6} thermionic rf gun cathodes. For each, particle simulation codes are used to simulate the BB effect and electron beam dynamics in a thermionic rf gun cathode. A semiempirical equation is also used to investigate the stopping range and deposited heat power of BB electrons in the cathode material. A numerical simulation method is used to calculate the change of the cathode temperature and current density during a single macropulse. This is done by solving two differential equations for the rf gun cavity equivalent circuit and one-dimensional thermal diffusion equation. High electron emission and small beam size are required for generation of a high-brightness electron beam, and so in this work the emission properties of the cathode are taken into account. Simulations of the BB effect show that, for a pulse of 6  μs duration, the DC cathode experiences a large change in the temperature compared with LaB_{6}, and a change in current density 6 times higher. Validation of the simulation results is performed using experimental data for beam current beyond the gun exit. The experimental data is well reproduced using the simulation method.

Many devices have been marketed in order to improve the organoleptic characteristics of tap water resulting from disinfection with chlorine derivates. The aim of the presented study was to assess the degree of contamination by non-fermenting Gram-negative bacteria (NF-GNB of drinking water dispensed from microfiltration devices at point-of-use. Methods. Water samples were collected from 94 point-of-use water devices fitted with a filter (0.5μm pore size containing powdered activated carbon. The microbiological contamination of water entering and leaving the microfiltered water dispensers was compared. The NF-GNB loads were correlated to Total Heterotrophic Counts (HPCs at 37 and 22 °C, residua chlorine, and some structural and functional features of the devices. Results. NF-GNB were detected from 23% of supply water samples, 33% of still unchilled water, 33% of still chilled water and 18% of carbonated chilled water. The most frequent isolates were Pseudomonadaceae: Steno.maltophilia 30.2% of isolates, Pseudomonas 20.5%, Delftia acidovorans 13.4%, while the species more largely distributed was Ps. aeruginosa recovered from 13% of samples. The distribution of the various NF-GNB was different in the water entering and in that leaving the devices. Ps.aeruginosa and Steno.maltophilia were the predominant species in water leaving the microfiltration dispensers, probably due to their capacity to colonize the circuits and to prevail over the others. Recovery of NF-GNB was favoured by the reduction in residual chlorine of the supply water, occasional use, the absence of a bacteriostatic element in the filter and inadequate disinfection of the water lines. Conclusions. The presence of high concentrations of potentially pathogenic species of NF-GNB (Ps.aeruginosa, Steno. maltophilia, Burkhol.cepacia in the water dispensed from microfiltration devices represents a risk of waterborne infections for vulnerable individuals.

    Many devices have been marketed in order to improve the organoleptic characteristics of tap water resulting from disinfection with chlorine derivates.

    To describe the implementation of a unitary dose drug dispensation system (UDDDS) with computerized medical orders in an intensive care unit (ICU) including 10 multi-purpose offices, and to obtain a medication error index as an indicator of the process quality. A UDDDS with computerized medical orders for intensive care was defined. By consensus among nurses, intensivists and pharmacists, the administration of high-risk drugs by perfusion or through a gastric tube was protocolized, and computerized medical orders were adapted to ICU dynamics, with both fluid therapy and enteral and parenteral nutrition becoming fully integrated. A prospective observational 8-month study with 15 cross-sectional time points was performed to estimate the overall error index and mean error per drug use process stage. The error index is estimated by dividing the number of errors into error opportunities, and is expressed as a percentage. Computerized medical orders favored compliance with consensus protocols defined in software programs at the pharmacy department, even though the degree of adhesion degree was not quantitized. They also allowed a validation of all medical prescriptions by a pharmacist before dispensation. The total number of errors detected during the study period was 86. Error opportunities were 26,695, and the overall error index was 0.32%. During the study an error occurred every 312.5 error opportunities.

These DSCs had three specific recommendations for the safe use of LABA products in adult asthma treatment. Methods: We examined the initiation of LABA-containing products for adult asthma treatment using an intermittent time series approach in a claims database from 2003 to 2012. We assessed the alignment of dispensing patterns with the following 2010 FDA recommendations: 1 contraindicated use of single-ingredient (SI-LABA without an asthma controller medication (ACM; 2 a LABA should only be used when asthma is not adequately controlled on inhaled corticosteroids (ICSs or ACM; and 3 step-down asthma therapy (e.g., discontinue LABA when asthma control is achieved. Results: There were 477,922 adults (18–64 years old dispensed a new LABA during 2003–2012. Among LABA initiators, patients who initiated an SI-LABA and who did “not” have an ACM dispensed on the same date decreased from >9% in 2003 (the initial labeling change to <2% post 2010 DSCs (p-value <0.0001 in the segmented regression model. The proportion of asthma patients dispensed an ICS in 6 months prior to initiating LABA treatment did not increase. The proportion of patients with longer than 4 months of continuous treatment did not decrease over the study period. Conclusion: Although the decrease in SI-LABA initiation is consistent with FDA’s recommendations, low ICS dispensing before initiating a LABA and LABA continuation practices require further efforts

    To assess the impact of exposure misclassification on risk associations when using prescription databases as the source for drug exposure in pregnancy by applying results from a validation analysis of exposure classification. Linkage of data on 27,656 participants in the Norwegian Mother and Child Cohort Study (MoBa) with the Norwegian Prescription Database (NorPD). Exposure to selective serotonin reuptake inhibitors (SSRIs) was defined by dispensed drugs during pregnancy including different time windows before pregnancy. The validity of NorPD data was estimated using self-reported use in MoBa as the reference standard. We applied the results from the validation analysis on data from a Nordic study on SSRI use in pregnancy and risk of persistent pulmonary hypertension in the newborn. Sensitivity increased and specificity decreased when the time window in NorPD was expanded before pregnancy. Using the same time window as in the Nordic study (+90 days before pregnancy), for use in early pregnancy, the odds ratio (OR) corrected for misclassification was 2.6 compared with the OR of 1.6 in the Nordic study. Expansion of the time window to include intervals before pregnancy can lead to lower specificity and underestimation of risk associations. Copyright © 2013 Elsevier Inc. All rights reserved.

    Flexible manufacturing processes with continuously adjustable dose strengths are considered particularly innovative and interesting for applications in personalized medicine, continuous manufacturing, or early drug development. A piezo-actuated micro-valve has been investigated for the dispensing and depositioning of drug nanosuspensions onto substrates to facilitate the manufacturing of solid oral dosage forms. The investigated micro-valve has been characterized regarding dispensing behavior, mass flow, accuracy, and robustness. The amount of dispensed drug compound during 1 dispensing event could be continuously adjusted from a few micrograms to several milligrams with high accuracy. Fluid properties, dispensing parameters of the micro-valve, and the resulting steady state mass flow could be correlated adequately for low-viscous drug nanosuspensions. High-speed imaging was used to investigate the dispensing behavior of the micro-valve regarding the evolution of the dispensed drug nanosuspension after ejection from the nozzle and the behavior during impact on flat and dry solid substrates. The experimentally determined breakup length of the dispensed liquid jet could be correlated with a semiempirical equation. From image sequences of the jet impact, We-Re phase diagrams could be established, providing a profound understanding and systematic guidance for the controlled depositioning of the entire dispensed drug nanosuspension onto the substrate.

  16. Tiger Teams Technical Assistance: Reliable, Universal Open Architecture for Card Access to Dispense Alternative Fuels

    Energy Technology Data Exchange (ETDEWEB)

    2002-03-01

    Report discusses the dilemma of incorporating consistent, convenient, universal card access (or ''pay-at-the-pump'') systems into alternative fueling stations across the country. The state of California continues to be in the forefront of implementing alternative fuels for transportation applications. Aggressive efforts to deploy alternative fuel vehicles (AFVs) in California have highlighted the need to provide adequate fueling stations and develop appropriate, user-friendly means to purchase fuel at the pump. Since these fuels are not typically provided by petroleum companies at conventional fueling stations, and acceptance of cash is often not an option, a payment method must be developed that is consistent with the way individual AFV operators are accustomed to purchasing automotive fuels--with a credit card. At the same time, large fleets like the California Department of General Services must be able to use a single fuel card that offers comprehensive fleet management services. The Gas Technology Institute's Infrastructure Working Group (IWG) and its stakeholders have identified the lack of a common card reader system as a hurdle to wider deployment of AFVs in California and the United States. In conjunction with the U.S. Department of Energy's (DOE) National Clean Cities Program, the IWG has outlined a multi-phased strategy to systematically address the barriers to develop a more ''open'' architecture that's similar to the way gasoline and diesel are currently dispensed. Under the auspices of the IWG, survey results were gathered (circa 1999) from certain fuel providers, as a means to more carefully study card reader issues and their potential solutions. Pilot programs featuring card reader systems capable of accepting wider payment options have been attempted in several regions of the United States with mixed success. In early 2001, DOE joined the National Renewable Energy Laboratory (NREL), the

    Capillary forces provide a ubiquitous means of organizing micro- and nanoscale structures on substrates. In order to investigate the mechanism of capillary self-assembly and to fabricate complex ordered structures, precise control of the meniscus shape is needed. We present a precision instrument that enables deposition of liquid droplets spanning from 2 nl to 300 μl, in concert with mechanical manipulation of the liquid-substrate interface with four degrees of freedom. The substrate has sub-100 nm positioning resolution in three axes of translation, and its temperature is controlled using thermoelectric modules. The capillary tip can rotate about the vertical axis while simultaneously dispensing liquid onto the substrate. Liquid is displaced using a custom bidirectional diaphragm pump, in which an elastic membrane is hydraulically actuated by a stainless steel syringe. The syringe is driven by a piezoelectric actuator, enabling nanoliter volume and rate control. A quantitative model of the liquid dispenser is verified experimentally, and suggests that compressibility in the hydraulic line deamplifies the syringe stroke, enabling sub-nanoliter resolution control of liquid displacement at the capillary tip. We use this system to contact-print water and oil droplets by mechanical manipulation of a liquid bridge between the capillary and the substrate. Finally, we study the effect of droplet volume and substrate temperature on the evaporative self-assembly of monodisperse polymer microspheres from sessile droplets, and demonstrate the formation of 3D chiral assemblies of micro-rods by rotation of the capillary tip during evaporative assembly.

    Objective To investigate associations between exposure to air pollution and child and adolescent mental health. Design Observational study. Setting Swedish National Register data on dispensed medications for a broad range of psychiatric disorders, including sedative medications, sleeping pills and antipsychotic medications, together with socioeconomic and demographic data and a national land use regression model for air pollution concentrations for NO2, PM10 and PM2.5. Participants The entire population under 18 years of age in 4 major counties. We excluded cohort members whose parents had dispensed a medication in the same medication group since the start date of the register. The cohort size was 552 221. Main outcome measures Cox proportional hazards models to estimate HRs and their 95% CIs for the outcomes, adjusted for individual-level and group-level characteristics. Results The average length of follow-up was 3.5 years, with an average number of events per 1000 cohort members of ∼21. The mean annual level of NO2 was 9.8 µg/m3. Children and adolescents living in areas with higher air pollution concentrations were more likely to have a dispensed medication for a psychiatric disorder during follow-up (HR=1.09, 95% CI 1.06 to 1.12, associated with a 10 µg/m3 increase in NO2). The association with NO2 was clearly present in 3 out of 4 counties in the study area; however, no statistically significant heterogeneity was detected. Conclusion There may be a link between exposure to air pollution and dispensed medications for certain psychiatric disorders in children and adolescents even at the relatively low levels of air pollution in the study regions. The findings should be corroborated by others. PMID:27259522

    The hair-like cell appendages denoted as type IV pili are crucial for biofilm formation in diverse eubacteria. The protein complex responsible for type IV pilus assembly is homologous with the type II protein secretion complex. In the cyanobacterium Synechococcus elongatus PCC 7942, the gene Synpcc7942_2071 encodes an ATPase homologue of type II/type IV systems. Here, we report that inactivation of Synpcc7942_2071 strongly affected the suite of proteins present in the extracellular milieu (exo-proteome) and eliminated pili observable by electron microscopy. These results support a role for this gene product in protein secretion as well as in pili formation. As we previously reported, inactivation of Synpcc7942_2071 enables biofilm formation and suppresses the planktonic growth of S. elongatus. Thus, pili are dispensable for biofilm development in this cyanobacterium, in contrast to their biofilm-promoting function in type IV pili-producing heterotrophic bacteria. Nevertheless, pili removal is not required for biofilm formation as evident by a piliated mutant of S. elongatus that develops biofilms. We show that adhesion and timing of biofilm development differ between the piliated and non-piliated strains. The study demonstrates key differences in the process of biofilm formation between cyanobacteria and well-studied type IV pili-producing heterotrophic bacteria. © 2017 Society for Applied Microbiology and John Wiley & Sons Ltd.

    Melanocortin therapy by using adrenocorticotropic hormone (ACTH) or non-steroidogenic melanocortin peptides attenuates proteinuria and glomerular injury in experimental glomerular diseases and induces remission of nephrotic syndrome in patients with diverse glomerulopathies, even those resistant to steroids. The underlying mechanism remains elusive, but the role of melanocortin 1 receptor (MC1R) has been implicated and was examined here. Four patients with congenital red hair color and nephrotic syndrome caused by idiopathic membranous nephropathy or focal segmental glomerulosclerosis were confirmed by gene sequencing to bear dominant-negative MC1R mutations. Despite prior corticosteroid resistance, all patients responded to ACTH monotherapy and ultimately achieved clinical remission, inferring a steroidogenic-independent and MC1R-dispensable anti-proteinuric effect of melanocortin signaling. In confirmatory animal studies, the protective effect of [Nle(4), D-Phe(7)]-α-melanocyte stimulating hormone (NDP-MSH), a potent non-steroidogenic pan-melanocortin receptor agonist, on the lipopolysaccharide elicited podocytopathy was completely preserved in MC1R-null mice, marked by reduced albuminuria and diminished histologic signs of podocyte injury. Moreover, in complementary in vitro studies, NDP-MSH attenuated the lipopolysaccharide elicited apoptosis, hypermotility and impairment of filtration barrier function equally in primary podocytes derived from MC1R-null and wild-type mice. Collectively, our findings suggest that melanocortin therapy confers a proteinuria reducing and podoprotective effect in proteinuric glomerulopathies via MC1R-independent mechanisms.

    Multiple factors affect compliance with hand hygiene, including conspicuity of alcohol-gel dispensers. Previous studies have shown that flashing lights increase hand hygiene compliance; however, the durability of this effect has not been studied. We affixed flashing lights to hand sanitizer dispensers for a total of 6 weeks. Regression analysis was used to compare compliance rates between the beginning and end of the intervention. Our secondary objective was to determine whether compliance rates in cold weather could be improved by adding a sign separated in time and space from the dispensers. Flashing lights improved hand hygiene compliance from 11.8% to 20.7%, and this effect was unchanged over the 6-week study period. Fully charged lights resulted in a greater compliance increase. A preemptive sign did not have a significant effect on hand hygiene rates nor did absolute temperatures. Flashing lights are a simple, inexpensive way of improving hand hygiene. Brighter lights appear to have a greater effect; however, this must be balanced with annoyance in specific settings. Temperature did not have a significant effect; however, this may be because the relationship does not fit a linear model. Other interventions, such as signs, may need to be tailored specifically to individual hospital environments.

    Type 2 diabetes mellitus (T2DM) is a significant public health issue in New Zealand. Effective management and glycaemic control is critical for reducing diabetes-related complications. Treatment guidelines are well established in New Zealand. Using dispensing data as a proxy for prescribing data, this paper aims to describe the pattern of first- and second-line antidiabetic agent (AA) dispensing for T2DM in New Zealand and assess adherence with treatment guidelines. Analysis of national dispensing data for AA medications using the Pharmaceutical Collection database from 2007/08 to 2015/16. Metformin monotherapy remains the most commonly prescribed first-line T2DM medication prescribed, accounting for 85% of initial agents prescribed. Sulfonylureas are the most common second-line agents used, accounting for 70% of all second-line agents. There is a high degree of adherence with the T2DM treatment guidelines in New Zealand.

These warnings are based on case reports and there is controversy about the association. While spontaneous reporting of suicide-related events attributed to LTMA has risen dramatically, these data may be biased by the warnings. The objective of this study was to explore the relationship between LTMA and suicide deaths using event data preceding the Food and Drug Administration warnings.Methods: We conducted a mixed-effects Poisson regression analysis of the association between LTMA prescriptions dispensed and suicide deaths at the county level. Counts of suicide deaths in each US county, stratified by race, age group, gender, and year were obtained from the National Center for Health Statistics for the period January 1, 1999 to December 31, 2006. Counts of LTMA prescriptions dispensed in each US county were obtained from IMS Health Incorporated. The model estimated the overall suicide rate conditional on LTMA use, adjusted for age, gender, race, year

    To examine the financial viability of the Timor-Leste National Spectacle Program as it increases spectacle availability, affordability and uptake, particularly for Timor's poor. In rural areas, three models of ready-made spectacles were dispensed according to a tiered pricing structure of US$3.00, 1.00, 0.10 and 0.00. In addition, custom-made spectacles were available in the capital, Dili. Spectacle costs, dispensing data and income for the National Spectacle Program for 18 months from March 2007 were analyzed. Rural services dispensed 3415 readymade spectacles: 47.1% to women, and 51.4% at subsidized prices, being 39.8% at US$0.10 and 11.6% free. A profit of US$1,529 was generated, mainly from the sale of US$3.00 spectacles. Women (odds ratio, OR, 1.3, 95% confidence interval, CI, 1.1-1.4) and consumers aged ≥65 years (OR 2.1; 95% CI 1.7-2.6) were more likely to receive subsidized spectacles. Urban services dispensed 2768 spectacles; mostly US$3.00 readymade (52.8%) and custom-made single vision (29.6%) units. Custom-made spectacles accounted for 36.7% of dispensing, but 73.1% of the US$12,264 urban profit. The combined rural and urban profit covered all rural costs, leaving US$2,200 to meet administration and other urban expenses. It is instructive and encouraging that a national spectacle dispensing program in one of the ten poorest countries of the world can use tiered-pricing based on willingness-to-pay information to cover spectacle stock replacement costs and produce profit, while using cross-subsidization to provide spectacles to the poor.

The estimates according dispensations shows that the total levels (alpha4 = 0.00552 in La Cabrera and 0.00405 in Fuentes Carrionas) and the structures of consanguinity (C22/C33 = 0.43 and 0.34) are similar in both regions, but have evolved differently. Whereas in La Cabrera both parameters have remained stable, in Fuentes Carrionas they fluctuated through the period analysed. On studying the structure of consanguinity more closely using the isonymic method, it can be seen that in La Cabrera total consanguinity (Ft = 0.0206) should be attributed mainly to environmental factors (Fr = 0.0193) and to a lesser extent to socio-cultural factors (Fn = 0.0013), whereas in Fuentes Carrionas it derives, almost exclusively, from the former (Ft = 0.01270; Fr = 0.01589; Fn = -0.00325).

The main findings were: (a an average of 2.4 drugs per prescription in both groups; (b prescriptions filled out with 4 or more drugs accounted for 18.0% of internal and 17.6% of external prescriptions; (c 84.3% of internal and 85.5% of external prescriptions provided no instructions for use of medication; (d information on dosage regimen varied from 51.2% to 97.6% for internal and 57.9% to 96.5% for external prescriptions; (e generic names were specified for 51.9% and 28.4% of all drugs on internal and external prescriptions, respectively; (f prescriptions containing standard drugs from the Municipal Health Department accounted for 88.7% of internal and 76.4% of external prescriptions. Data analysis shows the need for continuing education of physicians and adoption of other methods to improve quality of prescriptions and promote rational use of drugs.

  8. Centriole assembly and the role of Mps1: defensible or dispensable?

    Full Text Available Abstract The Mps1 protein kinase is an intriguing and controversial player in centriole assembly. Originally shown to control duplication of the budding yeast spindle pole body, Mps1 is present in eukaryotes from yeast to humans, the nematode C. elegans being a notable exception, and has also been shown to regulate the spindle checkpoint and an increasing number of cellular functions relating to genomic stability. While its function in the spindle checkpoint appears to be both universally conserved and essential in most organisms, conservation of its originally described function in spindle pole duplication has proven controversial, and it is less clear whether Mps1 is essential for centrosome duplication outside of budding yeast. Recent studies of Mps1 have identified at least two distinct functions for Mps1 in centriole assembly, while simultaneously supporting the notion that Mps1 is dispensable for the process. However, the fact that at least one centrosomal substrate of Mps1 is conserved from yeast to humans down to the phosphorylation site, combined with evidence demonstrating the exquisite control exerted over centrosomal Mps1 levels suggest that the notion of being essential may not be the most important of distinctions.

  9. Myogenin regulates exercise capacity but is dispensable for skeletal muscle regeneration in adult mdx mice.

    Eric Meadows

    Full Text Available Duchenne muscular dystrophy (DMD is the most prevalent inherited childhood muscle disorder in humans. mdx mice exhibit a similar pathophysiology to the human disorder allowing for an in-depth investigation of DMD. Myogenin, a myogenic regulatory factor, is best known for its role in embryonic myogenesis, but its role in adult muscle maintenance and regeneration is still poorly understood. Here, we generated an mdx:Myog(flox/flox mouse harboring a tamoxifen-inducible Cre recombinase transgene, which was used to conditionally delete Myog during adult life. After tamoxifen treatment, three groups of mice were created to study the effects of Myog deletion: mdx:Myog(flox/flox mice (mdx, Myog(flox/flox mice (wild-type, and mdx:Myog(floxΔ/floxΔ:Cre-ER mice (mdx:Myog-deleted. mdx:Myog-deleted mice exhibited no adverse phenotype and behaved normally. When run to exhaustion, mdx:Myog-deleted mice demonstrated an enhanced capacity for exercise compared to mdx mice, running nearly as far as wild-type mice. Moreover, these mice showed the same signature characteristics of muscle regeneration as mdx mice. Unexpectedly, we found that myogenin was dispensable for muscle regeneration. Factors associated with muscle fatigue, metabolism, and proteolysis were significantly altered in mdx:Myog-deleted mice, and this might contribute to their increased exercise capacity. Our results reveal novel functions for myogenin in adult muscle and suggest that reducing Myog expression in other muscle disease models may partially restore muscle function.

  10. Identification of vital and dispensable sulfur utilization factors in the Plasmodium apicoplast.

    Joana M Haussig

    Full Text Available Iron-sulfur [Fe-S] clusters are ubiquitous and critical cofactors in diverse biochemical processes. They are assembled by distinct [Fe-S] cluster biosynthesis pathways, typically in organelles of endosymbiotic origin. Apicomplexan parasites, including Plasmodium, the causative agent of malaria, harbor two separate [Fe-S] cluster biosynthesis pathways in the their mitochondrion and apicoplast. In this study, we systematically targeted the five nuclear-encoded sulfur utilization factors (SUF of the apicoplast [Fe-S] cluster biosynthesis pathway by experimental genetics in the murine malaria model parasite Plasmodium berghei. We show that four SUFs, namely SUFC, D, E, and S are refractory to targeted gene deletion, validating them as potential targets for antimalarial drug development. We achieved targeted deletion of SUFA, which encodes a potential [Fe-S] transfer protein, indicative of a dispensable role during asexual blood stage growth in vivo. Furthermore, no abnormalities were observed during Plasmodium life cycle progression in the insect and mammalian hosts. Fusion of a fluorescent tag to the endogenous P. berghei SUFs demonstrated that all loci were accessible to genetic modification and that all five tagged SUFs localize to the apicoplast. Together, our experimental genetics analysis identifies the key components of the SUF [Fe-S] cluster biosynthesis pathway in the apicoplast of a malarial parasite and shows that absence of SUFC, D, E, or S is incompatible with Plasmodium blood infection in vivo.

    Full Text Available Objective: To assess the influence of pharmacists' opinions on their dispensing medicines with a «medical prescription only» label without requiring a doctor's prescription. Methods: We performed a cross-sectional study of 166 community pharmacies in northwest Spain. The opinions of pharmacists on the following were collected as independent variables through personal interview: a physicians' prescribing practices; b the pharmacist's qualifications to prescribe; c the responsibility of the pharmacist regarding the dispensed drugs; d the customer' qualifications for self-medication; and e the pharmacist's perception of his or her own work. The dependent variable was the pharmacist's demand for a medical prescription for 5 drugs, which in Spain require a prescription. Multiple linear regression models were constructed. Results: The response rate was 98.8%. A total of 65.9% of pharmacists reported dispensing antibiotics without a prescription. This percentage was 83.5% for nonsteroidal anti-inflammatory drugs, 46.3% for angiotensin-converting enzyme inhibitors, 13.4% for benzodiazepines, and 84.8% for oral contraceptives. Further results showed that pharmacists with a heavier workload and those who underestimated the physicians' qualifications to prescribe but overestimated their own qualifications to prescribe less frequently demanded medical prescriptions. In contrast, pharmacists who stressed the importance of their duty in rationalizing the consumption of drugs more frequently demanded medical prescriptions. Conclusion: Our results suggest that to increase the quality of dispensing: a the importance of the pharmacist's duty in controlling drug consumption should be stressed; b pharmacies' workload should be optimized; and c perceptions of physicians' prescribing practices among pharmacists should be improved.Objetivo: Evaluar la influencia de las opiniones de los farmacéuticos que no solicitan receta médica para dispensar fármacos que la

    Full Text Available Orientation: Underpinning healthcare service delivery are a number of support systems. This paper focuses on the development of a healthcare services framework that reflects the systems that need to be integrated, from a technology healthcare support perspective.Research purpose: The purpose of this paper is gain an understanding of some of the intricacies associated with the management of the transition to a future South African healthcare dispensation, with reference to the convergence of technology, financial healthcare and socio-political systems.Motivation for the study: South Africa is in the process of implementing the National Health Insurance initiative and the approach adopted will have a significant impact on the business model design.Research design, approach and method: A multidisciplinary literature study was undertaken. In addition, a limited narrative enquiry was also conducted. Practitioners interviewed were from the healthcare, informatics and management and technology sectors respectively. The research study constituted an insight study – analytically descriptive and not statistical in nature.Main findings: The literature reflects two very contrasting and different business models of healthcare service provision, namely a primarily curative and preventative stance. Each assumes a very different convergence of technology, healthcare, financial and social systems and consequently gives rise to contrasting business models. The dominant model appears to be based on primary healthcare, with a different technology support infrastructure to the previously-adopted curative approach. It is a model that would also appear to necessitate a complex adaptive management approach, necessitating a bottom-up as opposed to a top-down hierarchal management orientation.Contribution/Value-add: The National Healthcare Insurance initiative entails a very fundamental restructuring of the healthcare infrastructure.

    Acoustic droplet ejection (ADE) technology uses focused acoustic energy to transfer nanoliter-scale liquid droplets with high precision and accuracy. This noncontact, tipless, low-volume dispensing technology minimizes the possibility of cross-contamination and potentially reduces the costs of reagents and consumables. To date, acoustic dispensers have mainly been used in screening libraries of compounds. In this paper, we describe the first application of this powerful technology to the rapidly developing field of synthetic biology, for DNA synthesis and assembly at the nanoliter scale using a Labcyte Echo 550 acoustic dispenser. We were able to successfully downscale PCRs and the popular one-pot DNA assembly methods, Golden Gate and Gibson assemblies, from the microliter to the nanoliter scale with high assembly efficiency, which effectively cut the reagent cost by 20- to 100-fold. We envision that acoustic dispensing will become an instrumental technology in synthetic biology, in particular in the era of DNA foundries. © 2015 Society for Laboratory Automation and Screening.

    Dilutions are a common source of analytical error, both in terms of accuracy and precision, and a common source of analyst mistakes. When serial dilutions are used, errors compound, even when employing laboratory automation. Direct point dilutions instead of serial dilutions can reduce error but is often impractical as they require either large diluent volumes or very small sample volumes when performed with traditional liquid handling equipment. We evaluated preparation of dilution curves using a picoliter digital dispenser, the HP, Inc. / TECAN D300 which is capable of accurately delivering picoliter volumes directly into sample wells filled with assay diluent. Dilution linearity and variability of the direct dilutions were similar to or less than those generated with a traditional liquid handler as measured using a fluorophore assay and an ELISA used to measure vaccine potency. Minimum concentrations for detergent in the dispensed sample were identified but no correlation with detergent characteristics was observed. The tolerance to protein in the sample was evaluated as well with up to 5% BSA having no impact on dispense linearity and precision. We found the digital dispenser to reduce automation complexity while maintaining or improving assay performance in addition to facilitating complex plate lay-outs. Copyright © 2017 Elsevier B.V.

    Moldless lens manufacturing techniques using standard droplet dispensing technology often require precise control over pressure to initiate fluid flow and control droplet formation. We have determined a series of interfacial fluid parameters optimised using standard 3D printed tools to extract, dispense and capture a single silicone droplet that is then cured to obtain high quality lenses. The dispensing process relies on the recapitulation of liquid dripping action (Rayleigh-Plateau instability) and the capturing method uses the interplay of gravitational force, capillary forces and liquid pinning to control the droplet shape. The key advantage of the passive lens fabrication approach is rapid scale-up using 3D printing by avoiding complex dispensing tools. We characterise the quality of the lenses fabricated using the passive approach by measuring wavefront aberration and high resolution imaging. The fabricated lenses are then integrated into a portable imaging system; a wearable thimble imaging device with a detachable camera housing, that is constructed for field imaging. This paper provides the full exposition of steps, from lens fabrication to imaging platform, necessary to construct a standalone high resolution imaging system. The simplicity of our methodology can be implemented using a regular desktop 3D printer and commercially available digital imaging systems.

  5. International Space Station USOS Potable Water Dispenser On-Orbit Functionality vs Design

    The International Space Station (ISS) currently provides potable water dispensing for rehydrating crewmembers food and drinking packages with one system located in the United States On-orbit Segment (USOS) and one system in the Russian Segment. The USOS Potable Water Dispenser (PWD) was delivered to ISS on ULF2, Shuttle Mission STS-126, and was subsequently activated in November 2008. The PWD activation on ISS is capable of supporting an ISS crew of six but nominally supplies only half the crew. The PWD is designed to provide incremental quantities of hot and ambient temperature potable water to US style food packages. PWD receives iodinated water from the US Laboratory Fuel Cell Water Bus, which is fed from the Water Processing Assembly (WPA). The PWD removes the biocidal iodine to make the water potable prior to dispensing. A heater assembly contained within the unit supplies up to 2.0 liters of hot water (65 to 93oC) every thirty minutes. This quantity supports three to four crewmembers to rehydrate their food and beverages from this location during a single meal. The unit is designed to remain functional for up to ten years with replacement of limited life items such as filters. To date, the PWD on-orbit performance has been acceptable. Since activation of the PWD, there have been several differences between on-orbit functionality and expected performance of hardware design. The comparison of on-orbit functionality to performance of hardware design is outlined for the following key areas: microbiology, PWD to food package water leakage, no-dispense scenarios, under-dispense scenarios, and crewmember feedback on actual on-orbit use.

    Electrical interconnections are essential for the integration of electronic functions in a fabric. These interconnects can be dispenser printed on a fabric; however printing directly on a breathable woven fabric surface is challenging due to the high surface variation and porosity defined by the weave. This paper, for the first time, experimentally shows that fabric surface variation leads to inconsistent printed structures which adversely affects the electrical properties of printed conductive tracks. It investigates a solution of overcoming the fabric surface variation in the form of dispenser printing an interface layer between the conductive ink and the fabric surface. Four dielectric inks DuPont 5018, Electra EFV4/4965, Fabinks-UV-IF-1004 and Fabinks-UV-TC0233 are quantitatively evaluated, as interface materials, in terms of surface consistency, thickness consistency, repeatability, flexibility, thermal stability and the electrical characteristics of conductive tracks printed on them. All four of the evaluated interface materials significantly reduced the fabric surface variation by more than 95% and provided a suitable low variation surface for printing subsequent electronic layers. Conductive tracks, dispenser printed on the four interface materials, produced ∼90% lower electrical resistivity compared to tracks printed directly on the fabric and similar resistivity to dispenser printed tracks on Kapton, a traditional printed electronic substrate. An increased focus on low powered electronics especially for wearables requires the electrical interconnections to dissipate minimum power. The innovative interface layer approach allows fabrication of low resistance electrical interconnections on fabric substrates reducing interconnect power dissipation, making this approach highly suitable for smart fabric applications. Reported details of dispenser printing of interface materials can be used for replicating these results on a range of fabric substrates. The

  8. 3D chip stacking with through silicon-vias (TSVs) for vertical interconnect and underfill dispensing

    2017-04-01

    3D chip stacking with through silicon vias (TSVs) has been identified as one of the major technologies for achieving higher silicon packaging density and shorter interconnect. The test vehicle presented in this paper is a 3D chip stack package. Each layer of the test vehicle has two silicon flip chips mounted at the bottom of a silicon interposer with solder bumps. The flip chip has the equivalent dimensions and pad patterns as commercial memory chips. The interposer, with multiple interconnect TSVs for electrical connection and a central TSV for underfill dispensing, can function as a logic chip or as a redistribution chip in a real application. The assembly steps of the test vehicle include conductive adhesive filling for the interconnect TSVs, bonding two bumped flip chips on an interposer (to form a single layer), vertical stacking of the single layers and underfill dispensing. For the filling of the interconnect TSVs, an auger-dispensing method is first adopted to overfill the interconnect TSVs, followed by removing the excessive adhesive beyond the interconnect TSVs by squeegeeing. A jet valve continuously dispenses free dots of an underfill encapsulant into the central TSVs. The central TSVs function as an entrance for underfill dispensing and an uninterrupted point-source to provide fluid for each layer. The free dots form a capillary flow to fill the under-chip spaces of the test vehicle. The usage of TSVs rather than chip edges eliminates the presence of a wide edge reservoir, resulting in smaller ‘keep-out’ area occupation on the substrate.

    Televised direct-to-consumer advertising (DTCA) for prescription drugs is controversial, especially for tobacco cessation products such as varenicline, given safety concerns that arose only after its market approval. We aim to quantify the extent to which DTCA influenced varenicline use. We linked monthly DTCA television ratings with monthly prescription data from IMS Health's National Prescription Audit across top 75 media markets in 2006-2009. We used Poisson models with Generalized Estimating Equations to analyze effects of exposures to DTCA for both varenicline and nicotine replacement therapies on rate of dispensed varenicline prescriptions among smokers, controlling for population characteristics and varenicline-related events. Varenicline prescriptions increased dramatically following DTCA launch and declined sharply after safety risks were publicized and US Food and Drug Administration (FDA) issued an advisory. DTCA had significant impact on new prescription dispensing in the subsequent month: before the FDA advisory, one additional exposure to varenicline DTCA was associated with a 1.8% (rate ratio [RR] = 1.018 [1.015-1.021]) higher rate of new prescriptions; no effect was observed after the advisory (RR = 1.000 [0.997-1.003]). Prior to the advisory, cross-product effects of nicotine replacement therapy advertising on varenicline prescribing were negligible (RR = 1.002 [0.999-1.004]); after the advisory, effects were positive (RR = 1.015 [1.012-1.019]). DTCA for varenicline had a significant impact on varenicline prescribing when the drug's safety profile was not well characterized, supporting arguments to limit DTCA for newly approved products whose real-world safety is unclear. We examined the fluctuations in varenicline use in association with DTCA for varenicline and other tobacco cessation aids. To our knowledge this is the first study to quantify the effects of televised DTCA for varenicline and other tobacco cessation aids on varenicline

    To assess the effectiveness of an educational intervention on antibiotic adherence and patient-reported resolution of symptoms. A controlled experimental study with systematic assignment to groups. A pharmacy in Murcia. Participants were patients who came to the pharmacy with a prescription for antibiotics. Intervention provided information on treatment characteristics (duration, dose and method of use) and correct compliance. A control group received routine care. Main variables "treatment adherence" and "perceived health" were evaluated one week after dispensation by telephone interview. A total of 126 patients completed the study, 62 in the Control Group (CG) and 64 in the Intervention Group (IG). There were no differences between the groups in baseline characteristics, including the level of knowledge before the intervention. At the end of the study, treatment adherence in the CG was 48.4% (CI: 36.4-60.6), compared with 67.2% (CI: 55.0-77.4) in the IG. The difference of 18.8% was statistically significant (p=0.033; 95% CI=15.8-34.6). Non-compliance through missing more than one dose was 81.2% in the CG versus 38.1% in the IG, which is a statistically significant difference of 43.1% (p=0.001; 95% CI=16.4-63.1%). No significant differences were found in patient-perceived health. Logistic regression showed as predictor of adherence, the medication knowledge and the coincidence between duration of treatment indicated by physician and duration of treatment written in the prescription. An educational intervention during antibiotic dispensation improves treatment adherence versus routine care. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

  12. SCD1 Expression is dispensable for hepatocarcinogenesis induced by AKT and Ras oncogenes in mice.

    Directory of Open Access Journals (Sweden)

    Lei Li

    Full Text Available Increased de novo lipogenesis is one of the major metabolic events in cancer. In human hepatocellular carcinoma (HCC, de novo lipogenesis has been found to be increased and associated with the activation of AKT/mTOR signaling. In mice, overexpression of an activated form of AKT results in increased lipogenesis and hepatic steatosis, ultimately leading to liver tumor development. Hepatocarcinogenesis is dramatically accelerated when AKT is co-expressed with an oncogenic form of N-Ras. SCD1, the major isoform of stearoyl-CoA desaturases, catalyzing the conversion of saturated fatty acids (SFA into monounsaturated fatty acids (MUFA, is a key enzyme involved in de novo lipogenesis. While many studies demonstrated the requirement of SCD1 for tumor cell growth in vitro, whether SCD1 is necessary for tumor development in vivo has not been previously investigated. Here, we show that genetic ablation of SCD1 neither inhibits lipogenesis and hepatic steatosis in AKT-overexpressing mice nor affects liver tumor development in mice co-expressing AKT and Ras oncogenes. Molecular analysis showed that SCD2 was strongly upregulated in liver tumors from AKT/Ras injected SCD1(-/- mice. Noticeably, concomitant silencing of SCD1 and SCD2 genes was highly detrimental for the growth of AKT/Ras cells in vitro. Altogether, our study provides the evidence, for the first time, that SCD1 expression is dispensable for AKT/mTOR-dependent hepatic steatosis and AKT/Ras-induced hepatocarcinogenesis in mice. Complete inhibition of stearoyl-CoA desaturase activity may be required to efficiently suppress liver tumor development.

  13. Bazooka/PAR3 is dispensable for polarity in Drosophila follicular epithelial cells

    Full Text Available Apico-basal polarity is the defining characteristic of epithelial cells. In Drosophila, apical membrane identity is established and regulated through interactions between the highly conserved Par complex (Bazooka/Par3, atypical protein kinase C and Par6, and the Crumbs complex (Crumbs, Stardust and PATJ. It has been proposed that Bazooka operates at the top of a genetic hierarchy in the establishment and maintenance of apico-basal polarity. However, there is still ambiguity over the correct sequence of events and cross-talk with other pathways during this process. In this study, we reassess this issue by comparing the phenotypes of the commonly used baz4 and baz815-8 alleles with those of the so far uncharacterized bazXR11 and bazEH747 null alleles in different Drosophila epithelia. While all these baz alleles display identical phenotypes during embryonic epithelial development, we observe strong discrepancies in the severity and penetrance of polarity defects in the follicular epithelium: polarity is mostly normal in bazEH747 and bazXR11 while baz4 and baz815-8 show loss of polarity, severe multilayering and loss of epithelial integrity throughout the clones. Further analysis reveals that the chromosomes carrying the baz4 and baz815-8 alleles may contain additional mutations that enhance the true baz loss-of-function phenotype in the follicular epithelium. This study clearly shows that Baz is dispensable for the regulation of polarity in the follicular epithelium, and that the requirement for key regulators of cell polarity is highly dependent on developmental context and cell type.

    The effects of a direct refill program for automated dispensing cabinets (ADCs) on medication-refill errors were studied. This study was conducted in designated acute care areas of a 386-bed academic medical center. A wholesaler-to-ADC direct refill program, consisting of prepackaged delivery of medications and bar-code-assisted ADC refilling, was implemented in the inpatient pharmacy of the medical center in September 2009. Medication-refill errors in 26 ADCs from the general medicine units, the infant special care unit, the surgical and burn intensive care units, and intermediate units were assessed before and after the implementation of this program. Medication-refill errors were defined as an ADC pocket containing the wrong drug, wrong strength, or wrong dosage form. ADC refill errors decreased by 77%, from 62 errors per 6829 refilled pockets (0.91%) to 8 errors per 3855 refilled pockets (0.21%) (p error type detected before the intervention was the incorrect medication (wrong drug, wrong strength, or wrong dosage form) in the ADC pocket. Of the 54 incorrect medications found before the intervention, 38 (70%) were loaded in a multiple-drug drawer. After the implementation of the new refill process, 3 of the 5 incorrect medications were loaded in a multiple-drug drawer. There were 3 instances of expired medications before and only 1 expired medication after implementation of the program. A redesign of the ADC refill process using a wholesaler-to-ADC direct refill program that included delivery of prepackaged medication and bar-code-assisted refill significantly decreased the occurrence of ADC refill errors.

    This paper presents a deterministic bead-in-droplet ejection (BIDE) technique that regulates the precise distribution of microbeads in an ejected droplet. The deterministic BIDE was realized through the effective integration of a microfluidic single-particle handling technique with a liquid dispensing system. The integrated bead dispenser facilitates the transfer of the desired number of beads into a dispensing volume and the on-demand ejection of bead-encapsulated droplets. Single bead-encapsulated droplets were ejected every 3 s without any failure. Multiple-bead dispensing with deterministic control of the number of beads was demonstrated to emphasize the originality and quality of the proposed dispensing technique. The dispenser was mounted using a plug-socket type connection, and the dispensing process was completely automated using a programmed sequence without any microscopic observation. To demonstrate a potential application of the technique, bead-based streptavidin-biotin binding assay in an evaporating droplet was conducted using ultralow numbers of beads. The results evidenced the number of beads in the droplet crucially influences the reliability of the assay. Therefore, the proposed deterministic bead-in-droplet technology can be utilized to deliver desired beads onto a reaction site, particularly to reliably and efficiently enrich and detect target biomolecules.

    Evidence of safety issues associated with long-acting beta 2 -agonist (LABA) treatment has led to multiple regulatory activities by the U.S. Food and Drug Administration (FDA) on this class of medications. This study describes the impact of the regulatory activities on incident LABA-containing medication dispensing. A monthly rolling cohort of asthma patients who were eligible to initiate a LABA-containing product was created in the Mini-Sentinel Distributed Database between January 2005 and June 2011. Cohorts of individuals who initiated LABA were examined for the changes in the proportions of single-ingredient to fixed-dose inhaled corticosteroid (ICS)-LABA initiators, appropriate initiation of LABA-containing products, and use of controller medications. The impact of the 2005 and 2010 FDA regulatory activities associated with LABA-containing products was measured using interrupted time series with segmented regression. LABA-containing product initiation was declining prior to the 2005 regulatory activities and continued to decline over the study period, accompanied by increased initiation of fixed dose ICS-LABA among LABA initiators. While the 2010 regulatory activities had no immediate impact on the proportion of LABA initiation in patients with prior controller medication dispensing and/or poor asthma control, there was an increasing positive trend toward LABA initiation in the appropriate patient population after the regulatory activities. The 2005 and 2010 FDA regulatory activities likely had an impact on communicating the safety concerns of LABA products. However, the impact cannot be viewed independent of scientific publications, guidelines for asthma treatment and other regulatory activities.

    Full Text Available The aim of the present study was to evaluate the microbiological quality of hot beverages dispensed by vending machines (VMs. The study was carried out on 203 samples from 15 VMs located in 5 Army barracks in Messina. The samples included: water used for preparation of beverages, swab of water tank, swab of blender machine, chocolate powder, milk powder, cappuccino and chocolate drink (29 samples for each types. All samples were examined for total bacterial count (TBC, coliforms, Escherichia coli, enterococci, Pseudomonas aeruginosa, Staphylococcus aureus, Clostri - dium perfringens, Aeromonas spp., Salmonella spp. and Listeria monocytogenes. For the water samples the colony count (CC at 22°C and at 37°C was made. The average values of CC at 22°C and at 37°C were of 10.86x10²±8.72x10² CFU/mL and of 21.72x10²±16.44x10² CFU/mL, respectively. P. aeruginosa, coliform bacteria, S. aureus, E. coli and molds were detected from water. The TBC ranged from 176 CFU/g (±275.2 for chocolate powder to 294.8±69.4 CFU/g for milk powder. S. aureus and molds were isolated from milk powder, while coliforms, E. coli and S. aureus were observed in chocolate powder. The average TBC for hot beverages ranged from 34.32x10³±97.77x10³ CFU/mL for cappuccino to 36.59x10³±10.47x104 CFU/mL for chocolate drink. Coliforms, E. coli, enterococci and molds were detected from cappuccino, while enterococci and molds were observed in chocolate drink. The microbiological characteristics of the water and powders, hygiene, and the periodic cleaning of machines, influenced the microbiological quality of the hot beverages dispensed by VMs.

    Full Text Available Panx1 forms plasma membrane channels in brain and several other organs, including the inner ear. Biophysical properties, activation mechanisms and modulators of Panx1 channels have been characterized in detail, however the impact of Panx1 on auditory function is unclear due to conflicts in published results. To address this issue, hearing performance and cochlear function of the Panx1−/− mouse strain, the first with a reported global ablation of Panx1, were scrutinized. Male and female homozygous (Panx1−/−, hemizygous (Panx1+/− and their wild type (WT siblings (Panx1+/+ were used for this study. Successful ablation of Panx1 was confirmed by RT-PCR and Western immunoblotting in the cochlea and brain of Panx1−/− mice. Furthermore, a previously validated Panx1-selective antibody revealed strong immunoreactivity in WT but not in Panx1−/− cochleae. Hearing sensitivity, outer hair cell-based “cochlear amplifier” and cochlear nerve function, analyzed by auditory brainstem response (ABR and distortion product otoacoustic emission (DPOAE recordings, were normal in Panx1+/− and Panx1−/− mice. In addition, we determined that global deletion of Panx1 impacts neither on connexin expression, nor on gap-junction coupling in the developing organ of Corti. Finally, spontaneous intercellular Ca2+ signal (ICS activity in organotypic cochlear cultures, which is key to postnatal development of the organ of Corti and essential for hearing acquisition, was not affected by Panx1 ablation. Therefore, our results provide strong evidence that, in mice, Panx1 is dispensable for hearing acquisition and auditory function.

    There are approximately 6,300 people in Ireland with a diagnosis of Chronic Obstructive Pulmonary Disease (COPD) and with a fast growing elderly population the incidence of COPD is likely to increase. This study examines the prescribing patterns of medicines dispensed for the management Asthma\\/COPD in patients over the age of 35 years using the HSE-Primary Care Reimbursement Services (PCRS) prescribing databases. The HSE-PCRS pharmacy claims data, which covers all those over 70 years of age and means tested for those less than 70 years, was analysed for the years 2005\\/2006. Approximately 26,548 (17.9%) of patients who were prescribed a respiratory drug received inhaled short-acting beta2 agonists in combination with a regular standard-dose inhaled corticosteroid. A further 5,044 (3.4%) were also prescribed a regular inhaled long-acting beta2 agonist (salmeterol or formoterol). A total of 2506 patients (6.2%) on combination therapy were co-prescribed four different anti-asthmatic treatments inclusive of oral prednisolone. A small proportion of the patients prescribed a respiratory drug were co-prescribed nicotine replacement therapy (n = 5177, 3.5%). In total there were 9,728 (6.2%) patients prescribed a mucolytic drug in combination with a respiratory drug and the rate of co-prescribing with antibiotics was 22%. COPD is a debilitating disease that is primarily caused by smoking and is therefore largely preventable. The HSE-PCRS pharmacy claims data is a valuable tool for helping to assess the burden of this disease in the Irish context.

    To assess the potential to suppress Mediterranean fruit fly, Ceratitis capitata (Wiedemann; Diptera: Tephritidae), via mass trapping with Trimedlure (TML), we compared fly catch (as catch per trap per time period) provided by either a novel, solid, triple-lure dispenser with TML, methyl eugenol (ME), and raspberry ketone (RK) (TMR) or solid TML plugs, both without insecticides, in addition to Biolure bait stations. Work was done in a coffee plantation that had a dense C. capitata population. Three treatments were compared: 1) TMR or TML (50 traps per ha), 2) Biolure (50 traps per ha), 3) TML (25 per ha) or TMR (25 per ha) + Biolure (25 per ha), and 4) an untreated control. During coffee season, based on C. capitata captures (mean flies per trap per wk) inside plastic McPhail traps, all treatments were significantly different than the control: Biolure (9.57) = TMR (11.28) = Biolure +TMR (13.50) < Control (36.06 flies/trap/wk). During non-coffee season, all treatments were significantly different than the control and TML was significantly lower than Biolure (wax matrix bait stations): TML (0.95) < Biolure (1.43) = Biolure +TML (1.77) < Control (2.81 flies/trap/wk). Surprisingly, captures were not lower in plots treated with combinations of Biolure + TMR or TML, compared to individual plots with Biolure or TML or TMR alone. Mass trapping with either TML or TMR dispensers deserves further study as a component of Integrated Pest Management programs for C. capitata in Hawaii and may have global potential for management of C. capitata.

    To characterise the differences in care seeking behaviour and dispensing outcomes between adults and children purchasing drugs for malaria at retail shops in Nigeria. In Nasarawa State, retail drug shops were enumerated and a subset of those stocking antimalarials were selected as study sites and surveyed. Customers exiting shops after purchasing antimalarial drugs were surveyed and tested with a malaria rapid diagnostic test. Sick adults and caregivers accompanying sick children were eligible, but individuals purchasing drugs for a sick person that was not present were excluded. Multivariate regression analysis was used to identify the correlates of care seeking and the quality of interaction at the shop. Of 737 participants, 80% were adults and 20% were children (under age 18). Caregivers of sick children were more likely to obtain a prescription prior to attending a drug retailer than adults seeking care for themselves and waited a shorter time before seeking care. Caregivers of sick children were also more likely than sick adults to have been asked about symptoms by the retailer, to have been given an examination, and to have purchased an ACT. Fewer than half of respondents had purchased an ACT. Only 14% of adults, but 27% of children were RDT-positive; RDT-positive children were more likely to have had an ACT purchased for them than RDT-positive adults. Children with suspected malaria tend to receive better care at drug retailers than adults. The degree of overtreatment and prevalence of dispensing non-recommended antimalarials emphasise the need for routine diagnosis before treatment to properly treat both malaria and non-malaria illnesses. © 2015 The Authors.

    National guidelines recommend that patients with anaphylaxis be prescribed an epinephrine auto-injector (EAI) and referred to an allergy/immunology (A/I) specialist. To evaluate guideline concordance and identify predictors of EAI dispensing and A/I follow-up in patients with anaphylaxis treated in the emergency department (ED). We identified patients seen in the ED for anaphylaxis from 2010 through 2014 from an administrative claims database using an expanded International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code algorithm. Of 7,790 patients identified, 46.5% had an EAI dispensed and 28.8% had A/I follow-up within 1 year after discharge. On multivariable analysis, those 65 years or older (odds ratio [OR] 0.35, 95% confidence interval [CI] 0.30-0.41) and with a medication trigger (OR 0.24, 95% CI 0.21-0.28) had a lower likelihood of EAI dispensing. Those younger than 5 years (OR 2.67, 95% CI 2.15-3.32) and with food (OR 1.40, 95% CI 1.24-1.59) or venom (OR 4.48, 95% CI 3.51-5.72) triggers had a higher likelihood of EAI dispensing. Similarly, for A/I follow-up, the likelihood was lower for age 65 years or older (OR 0.46, 95% CI 0.39-0.54) and medication trigger (OR 0.66, 95% CI 0.56-0.78) and higher for age younger than 5 years (OR 3.15, 95% CI 2.63-3.77) and food trigger (OR 1.39, 95% CI 1.22-1.58). Overall, 46.5% of patients with anaphylaxis in the ED had EAI dispensing and 28.8% had A/I follow-up. Patient age and triggers were associated with likelihood of EAI dispensing and A/I follow-up. Post-ED visit anaphylaxis management can be improved, with the potential to decrease future morbidity and mortality risk. Copyright © 2017 American College of Allergy, Asthma & Immunology.

    2012-09-09

    Background Oral anticancer medicines (OAM) facilitate transfer of cancer care into the community, where safeguards developed in hospitals that control their prescribing, dispensing and administration may not exist. Objective To determine if the systems of prescribing and dispensing OAM in Ireland facilitate clinical verification of the prescription, thereby ensuring treatment is tailored and appropriate for the patient. Setting Randomly selected community pharmacies in Ireland and all Irish hospitals with cancer services. Method A questionnaire was sent to a random selection of Irish community pharmacists. A different questionnaire was sent to all Irish hospitals treating cancer patients. One hundred OAM prescriptions were retrospectively reviewed, to assess the information presented and the potential barriers to a community pharmacist performing a clinical verification of the prescription. Main outcome measure Community pharmacist survey: problems experienced when dispensing OAM and risk factors identified with the current system. Hospital pharmacist survey: proportion of hospitals that clinically verify prescriptions for parenteral versus oral anticancer medicines and associated policies. OAM prescription review: proportion of OAM prescriptions that contained sufficient information for a community pharmacist to clinically verify the prescription and safely dispense the medication. Results Sixty-four percent of community pharmacist respondents felt they did not have enough information available to them to safely dispense these prescriptions, and 74 % felt that patients are at risk with the current Irish system of prescribing and dispensing OAM. Irish hospitals do not have systems to ensure that all OAM prescriptions are clinically verified by a pharmacist. Seventeen different agents were prescribed on the prescriptions reviewed. The information provided to the community pharmacist would have allowed them to clinically verify 7 % of the OAM prescriptions

    To investigate patterns of early repeat prescriptions and treatment switching over an 11-year period to estimate differences in the cost of medication wastage, dispensing fees and prescriber time for short (prescription lengths from the perspective of the National Health Service in the UK. Retrospective, multiple cohort study of primary care prescriptions from the Clinical Practice Research Datalink. Five random samples of 50 000 patients each prescribed oral drugs for (1) glucose control in type 2 diabetes mellitus (T2DM); (2) hypertension in T2DM; (3) statins (lipid management) in T2DM; (4) secondary prevention of myocardial infarction; and (5) depression. The volume of medication wastage from early repeat prescriptions and three other types of treatment switches was quantified and costed. Dispensing fees and prescriber time were also determined. Total unnecessary costs (TUC; cost of medication wastage, dispensing fees and prescriber time) associated with prescriptions, standardised to a 120-day period, were then compared. Longer prescription lengths were associated with more medication waste per prescription. However, when including dispensing fees and prescriber time, longer prescription lengths resulted in lower TUC. This finding was consistent across all five cohorts. Savings ranged from £8.38 to £12.06 per prescription per 120 days if a single long prescription was issued instead of multiple short prescriptions. Prescriber time costs accounted for the largest component of TUC. Shorter prescription lengths could potentially reduce medication wastage, but they may also increase dispensing fees and/or the time burden of issuing prescriptions. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    2009-08-01

    The standard TopSpot technology has been successfully used in the recent years for the highly parallel nanoliter dispensing of bio-chemical substances for microarray printing. It is based on a pneumatically actuated printhead which enables non-contact microarray fabrication at a pitch of typically 500 microm. This paper reports on a new and improved way of operating the printheads termed TopSpot Vario technology, using an incompressible material between the piezo actuator and the dispensing medium. The advantage of the incompressible medium is the direct relation between the displacement amplitude and the ejected liquid volume. Earlier reports stated that the filling of the printheads is a key issue. In this paper we report on the implementation and characterization of a new printhead design including microchannels for bubble free priming of blind channels. Microarray fabrication was successfully conducted with four different types of protein.

    This letter reports two novel electrode design considerations to satisfy two very important aspects of EWOD operation—(1) Highly consistent volume of generated droplets and (2) Highly improved accuracy in the generated droplet volume. Considering the design principles investigated two novel designs were proposed; L-junction electrode design to offer high throughput droplet generation and Y-junction electrode design to split a droplet very fast while maintaining equal volume of each part. Devices of novel designs were fabricated and tested, and the results are compared with those of conventional approach. It is demonstrated that inaccuracy and inconsistency of droplet volume dispensed in the device with novel electrode designs are as low as 0.17 and 0.10%, respectively, while those of conventional approach are 25 and 0.76%, respectively. The dispensing frequency is enhanced from 4 to 9 Hz by using the novel design.

  8. Measurement of Low Workfunction Cesiated Metals for Use in Dispenser Photocathodes

    Moody, N A; O'Shea, P G

    2005-01-01

    Photoinjector performance is a limiting factor in the continued development of high powered FELs. Presently available photocathodes have limited efficiency and short lifetime in an RF-gun environment, due to contamination or evaporation of a photosensitive surface layer. An ideal photocathode should have high efficiency at visible wavelengths, long lifetime in practical vacuum environments, and prompt emission. High efficiency cathodes typically have limited lifetime, and the needs of the photocathode are generally at odds with those of the drive laser. A potential solution is the low work function dispenser cathode, where short lifetimes are overcome by periodic in situ regeneration that restores the photosensitive surface layer, analogous to methods used in the power tube industry. This work reports on the fabrication techniques and performance of cesiated metal photocathodes and cesiated dispenser cathodes, with a focus on understanding and improving quantum efficiency and lifetime, analyzing issues of emi...

    Full Text Available Prototheca spp. are colorless unicellular algae ubiquitous in nature and opportunistic pathogens for humans and animals. Since Prototheca is an important cause of bovine mastitis, milk, as well as dairy products, can be contaminated and represent a potential mean of transmission of this microorganism to man. We carried out a survey on the automatic milk dispensers in the Emilia-Romagna Region (Northern Italy, to evaluate human exposure to Prototheca through raw milk. Milk samples were collected from 177 automatic dispensers, distributing milk from 117 dairy herds. Prototheca spp. was isolated on 17 milk samples (9,6 % produced by 14 dairy herds. The results of molecular characterization indicate that the isolates were P. zopfii genotipe 2 e P. blaschkeae, both species being associated whit human diseases. Our investigation points out the importance of raw milk as a carrier of microorganisms potentially harmful to humans.

The effectiveness of these lures depends not only on their attractiveness to the mosquitoes but also on the medium from which they are dispensed. We report on the development and evaluation of nylon strips as a method of dispensing odorants attractive to the malaria vector, Anopheles gambiae s.s. (Giles). When a synthetic blend of attractants was dispensed using this method, significantly more mosquitoes were trapped than when two previous methods, open glass vials or low density polyethylene sachets were used. We conclude that the nylon strips are suitable for dispensing odorants in mosquito trapping operations and can be adopted for use in rural and remote areas. The nylon material required is cheap and widely available and the strips can be prepared without specialized equipment or electricity.

  13. Combinatorial dispensing as a fast and efficient means to create complex screens.

    Liquid handling robots carry out tasks from simple plate filling to complex operations such as creating reagent cocktails from multiple stock solutions. The latter task is conceptually a combinatorial process where each cocktail is created by combining a subset of stock solutions in user-defined volumes. General-purpose liquid handlers can perform this task, but their hardware lacks the inherent properties needed to exploit the combinatorial nature of the problem at hand. Here we present the use of non-contact dispensing technologies to create complex screens at low volume and high density. Our approach is based on the "inkjet printer principle" where a block of dispensers (print head) travels over a multi-well plate (paper) to deliver the reagents (inks) in a user-defined pattern. Impact-induced mixing and the lack of tip contamination remove the need for extensive tip washing or the use of large numbers of disposable tips. As an example, protein crystallization screening is used to demonstrate the technology. This application requires the creation of complex mixtures from many stock solutions with a great diversity of viscosities and surface tensions. In addition, dispense volumes cover a range from 50 nL to 50 microL, illustrating its utility in low-volume high-density screening.

    Pharmacists can play a critical role in the access to emergency contraception (EC). We assessed if knowledge and attitudes were predictive of EC dispensing among a statewide sample of Florida pharmacists, who have legal authority to refuse to dispense medications. In 2008, surveys were mailed to a random sample of 1264 pharmacists registered with the Florida Board of Pharmacy. Data from 272 pharmacists (22% response rate) were analyzed using bivariate and multivariate logistic regression. Fifty-six percent of respondents incorrectly answered that EC causes birth defects, and 46% replied that it causes abortion. Only 22% said that EC can be purchased in advance of need. Many felt uncomfortable dispensing to adolescents (61%) and men (58%). Knowledge about EC was the most important predictor of dispensing [odds ratio (OR)=1.57, 95% confidence interval (CI) 1.22-2.03]. In particular, pharmacists who reported that EC does not act as an abortifacient were more likely to dispense it (OR=4.64, 95% CI 2.15-10.00). Correct information about EC was the most important predictor of pharmacists' dispensing EC. To expand availability of EC, pharmacists will have to become better informed.

    A new concept for individualising the dosage of drugs in solid form is presented. The principle is based on the use of standardised units (microtablets), each containing a subtherapeutic amount of the active ingredient. The required dose is fine-tuned by counting out a specific number of these units. The microtablets are counted electronically from the attached cassette by the automatic dispensing device. The individual dose is set and the dispenser counts and delivers the correct number of microtablets. The usefulness of the automatic dispenser concept and acceptability of the apparatus were evaluated in patients with Parkinson's disease (PD). After initial instruction on use of the dispenser, 20 patients operated it themselves. All patients were generally satisfied with their management of the automatic dispenser and most would be happy to use the device again. Further technical development is required before use in clinical practice, but the current prototype may be acceptable for some patients. It is concluded that the final version of the automatic dose dispenser concept will offer potential for improvement of drug administration for patients with PD or other diseases requiring individual dosage.

    Modern insect pest management is faced with an increasingly sophisticated set of requirements. Control agent/dispenser combinations must be at the same time safe, nontoxic, inexpensive, reproducibly efficacious, environmentally compatible, biodegradable, and sustainable, and should be based on renewable resources. The methods employed preferably should be suitable for the growing and tightly controlled organic growing sector as well. All this calls for a level of sophistication and reproducibility previously unknown. Only very few systems can offer this kind of performance, but fortunately can be found in the area of suitable pheromone/dispenser combinations. This report is an attempt to adapt electrospun Ecoflex polyester micro fibers of the Greiner-Wendorff type to the very specific needs of the grape growing industry. Specifically required are "semi-intelligent" dispenser materials. On a weight basis, the electrospun product should achieve as high a proportion as possible of "retainable" sex pheromone (E,Z)-7,9-dodecadienyl acetate of Lobesia botrana (Lep.: Tortricidae) and should release it as uniformly as possible into the surrounding airspace. Using the Doye bioassay, some progress indeed has recently been achieved with electrospun Ecoflex microfibers of 0.5-3.5 microm diameter. They were employed as dispensers for programmed sex pheromone release with an effective mating disruption duration of up to seven weeks. With one microfiber/pheromone treatment, this covers one entire flight period of the trivoltine L. botrana. Mechanical application of this microfiber/pheromone preparation (with the option of automation) is possible. Disruption effects are comparable with those of commercially available dispensers of the Isonet type. Exposed under vineyard conditions, Ecoflex polyester fibers are a spider silk like material which is biodegradable within half a year. Thus, after releasing its pheromone load, it does not need removal, which saves one cultivation step

    Full Text Available Abstract Background In Tanzania, many people seek malaria treatment from retail drug sellers. The National Malaria Control Program identified the accredited drug dispensing outlet (ADDO program as a private sector mechanism to supplement the distribution of subsidized artemisinin-based combination therapies (ACTs from public facilities and increase access to the first-line antimalarial in rural and underserved areas. The ADDO program strengthens private sector pharmaceutical services by improving regulatory and supervisory support, dispenser training, and record keeping practices. Methods The government's pilot program made subsidized ACTs available through ADDOs in 10 districts in the Morogoro and Ruvuma regions, covering about 2.9 million people. The program established a supply of subsidized ACTs, created a price system with a cost recovery plan, developed a plan to distribute the subsidized products to the ADDOs, trained dispensers, and strengthened the adverse drug reactions reporting system. As part of the evaluation, 448 ADDO dispensers brought their records to central locations for analysis, representing nearly 70% of ADDOs operating in the two regions. ADDO drug register data were available from July 2007-June 2008 for Morogoro and from July 2007-September 2008 for Ruvuma. This intervention was implemented from 2007-2008. Results During the pilot, over 300,000 people received treatment for malaria at the 448 ADDOs. The percentage of ADDOs that dispensed at least one course of ACT rose from 26.2% during July-September 2007 to 72.6% during April-June 2008. The number of malaria patients treated with ACTs gradually increased after the start of the pilot, while the use of non-ACT antimalarials declined; ACTs went from 3% of all antimalarials sold in July 2007 to 26% in June 2008. District-specific data showed substantial variation among the districts in ACT uptake through ADDOs, ranging from ACTs representing 10% of all antimalarial sales

    Full Text Available Background: During the 1980s, manual repackaging of multi-dose medications from pharmacies in Sweden was successively substituted with automated multi-dose drug dispensing (MDD. There are few studies evaluating the consequences of automated MDD with regard to patient safety, and those that investigate this issue are not very extensive. Objectives: To investigate Swedish health care professionals’ perceived experience of automated MDD and its effects on patient adherence and patient safety. Methods: Three questionnaire forms, one for physicians, nurses, and assistant nurses/nursing assistants, were developed based on reviews of the literature and pilot testing of the questions in the intended target groups. The target groups were health professionals prescribing or administrating MDD to patients. A sample (every sixth municipality was drawn from the sampling frame of Swedish municipalities, resulting in 40 municipalities, about 14% of all municipalities in Sweden. Email addresses of general practitioners were obtained from county councils, while the municipalities assisted in getting contact details for nurses, assistant nurses and nursing assistants. A total of 915 questionnaires were distributed electronically to physicians, 515 to nurses, and 4,118 to assistant nurses/nursing assistants. The data were collected in September and October 2012. Results: The response rate among physicians, nurses and assistant nurses/nursing assistants was 31%, 43% and 23%, respectively. The professionals reported that automated MDD reduces duplication of medication, contributes to correct dosages, helps patients take their medication at the right time, and reduces confusion among patients. Fifteen per cent of the physicians and about one-third of the nurses and assistant nurses/nursing assistants reported that generic substitution makes it more difficult for the patient to identify the various medicines available in the sachets. The physicians did, however

    Increased intracellular reactive oxygen species (ROS) promote platelet activation. The sources of platelet-derived ROS are diverse and whether or not mitochondrial derived ROS, modulates platelet function is incompletely understood. Studies of platelets from patients with sickle cell disease, and diabetes suggest a correlation between mitochondrial ROS and platelet dysfunction. Therefore, we generated mice with a platelet specific knockout of superoxide dismutase 2 (SOD2-KO) to determine if increased mitochondrial ROS increases platelet activation. SOD2-KO platelets demonstrated decreased SOD2 activity and increased mitochondrial ROS, however total platelet ROS was unchanged. Mitochondrial function and content were maintained in non-stimulated platelets. However SOD2-KO platelets demonstrated decreased mitochondrial function following thrombin stimulation. In vitro platelet activation and spreading was normal and in vivo, deletion of SOD2 did not change tail-bleeding or arterial thrombosis indices. In pathophysiological models mediated by platelet-dependent immune mechanisms such as sepsis and autoimmune inflammatory arthritis, SOD2-KO mice were phenotypically identical to wildtype controls. These data demonstrate that increased mitochondrial ROS does not result in platelet dysfunction.

    The steady expansion in the capacity of modern beamlines for high-throughput data collection, enabled by increasing X-ray brightness, capacity of robotics and detector speeds, has pushed the bottleneck upstream towards sample preparation. Even in ligand-binding studies using crystal soaking, the experiment best able to exploit beamline capacity, a primary limitation is the need for gentle and nontrivial soaking regimens such as stepwise concentration increases, even for robust and well characterized crystals. Here, the use of acoustic droplet ejection for the soaking of protein crystals with small molecules is described, and it is shown that it is both gentle on crystals and allows very high throughput, with 1000 unique soaks easily performed in under 10 min. In addition to having very low compound consumption (tens of nanolitres per sample), the positional precision of acoustic droplet ejection enables the targeted placement of the compound/solvent away from crystals and towards drop edges, allowing gradual diffusion of solvent across the drop. This ensures both an improvement in the reproducibility of X-ray diffraction and increased solvent tolerance of the crystals, thus enabling higher effective compound-soaking concentrations. The technique is detailed here with examples from the protein target JMJD2D, a histone lysine demethylase with roles in cancer and the focus of active structure-based drug-design efforts.

Methods For each sample, microbial parameters and chemical indicators of contamination were evaluated and information about the date of installation, time since last ordinary and extraordinary maintenance of water coolers was collected. Results In all samples the chemical parameters (nitrite, ammonium, free active chlorine residual did not exceed the reference values of the drinking water regulation; the pH value in 86.8% samples of the carbonated waters was lower than the reference limit. The microbiological results indicated that the bacteria count at 22°C and 37°C was higher than the required values in 71% and 81% for the non-carbonated water and in 86% and 88% for the carbonated one, respectively. Enterococcus spp. and Escherichia coli were not detected in any of the water samples. Pseudomonas aeruginosa was found in only one sample of the tap water and in 28.9% and 23.7% of the non-carbonated and carbonated water samples, respectively. No statistically significant differences in bacterial counts at 22°C and 37°C have been found between the non-carbonated and carbonated water from the sampled coolers in relation with the time since the last filter was substituted. The bacteriological quality of tap water was superior to that of non-carbonated and carbonated water from coolers. Conclusion The results emphasize the importance of adopting appropriate routinely monitoring system in order to prevent or to diminish the chances of contamination of this water source.

    For the purpose of implementing steam sterilization of 2-[{sup 18}F]FDG (FDG) in the final container into routine production, we have validated and established a fully automated dispensing and sterilization system, thereby considerably reducing the radiation burden to the personnel. Methods: The commercially available system combines aseptic dispensing of the product solution under a miniaturized laminar flow unit with subsequent steam sterilization, realized by heating of the product in the final containers by an autoclave included in the dispensing unit, thus incorporating current pharmaceutical manufacturing standards for the production of parental radiopharmaceuticals. The efficiency of the used sterilization cycle, the stability of FDG under the conditions of sterilization and the stability of the final product towards radiolysis was investigated with respect to various pH-formulations. Results: The system was found to be fully valid for filling of vials in a laminar flow class A (US-class 100) environment and for sterilization of FDG in the final container. The pH for sterilizing FDG solutions must be slightly acidic to avoid decomposition. A pH of 5.5 appears to be optimal and gives FDG of very high radiochemical purity ({approx}99%). In addition, radiolysis of FDG in solutions of high activity concentration was significantly lower at pH 5.5 than at neutral pH. Conclusion: Terminal sterilization enables the production of FDG in full compliance with GMP-regulations even in Class C or D (US class 10,000 or 100,000) laboratories.

    Full Text Available Objective: To identify the process of dispensation of orthotics, prostheses and mobility aids (OPM by the Unified Health System (SUS in the Regional Health Department of the 3rd Region (DRSIII of Sao Paulo state; perform a mapping of the existing physical rehabilitation services in that region; and subsequently correlate the data with applicable laws. Methodology: This is an exploratory cross-sectional qualitative study whose subjects were the main professionals involved in the process of OPM dispensation, or responsible for their acquisition flow in the cities of that region. Data collection was carried out through a semi-structured questionnaire, developed by the researchers themselves, composed of questions aiming to identify the physical rehabilitation centers in the towns, the staff members involved, the provision of assistive technology through SUS, delivery time and existence of waiting lists. Results and discussion: The data were statistically measured, categorized, described and correlated with the current legislation aimed to guarantee access to assistive technology. We observed that the practice around this resource in the 3rd region concentrates in a single care center, causing long waits and poor efficiency of the services provided, in addition to maintaining a paternalistic aspect. Conclusion: This study provides evidence that, although the right to access to assistive technology is legally guaranteed, there are still many difficulties and challenges around this practice.

    2013-03-01

    Full Text Available Access to medication emphasizes the availability of the product at the expense of providing a service. The goal of this paper is to propose a theoretical model for a drug dispensing service, beginning with a reflection on the current realities of the Unified Health System and drug dispensation in Brazil. A conceptual analytical research made by a methodological course called disciplined imagination was mainly the approach applied to develop the model. The drug dispensing service is part of the care process, which considers access as an attribute; reception, connection and accountability, management, and clinical pharmaceutical aspects as components; and the rational use of drugs as the purpose. The proposed model addresses access to the dispensing service and demands a reorientation of routines, instruments, and practices.O acesso a medicamentos enfatiza a disponibilidade do produto em detrimento da provisão de um serviço. O objetivo deste trabalho é propor um modelo teórico para um serviço de dispensação de medicamentos, iniciando com uma reflexão sobre a realidade atual do Sistema Único de Saúde e a dispensação de medicamentos no Brasil. Uma pesquisa analítica conceitual realizada por meio de um percurso metodológico chamado de imaginação disciplinada constituiu a estratégia principal para o desenvolvimento do modelo. O serviço de dispensação é parte do processo de cuidado, o qual considera o acesso como um atributo; os aspectos acolhimento, vínculo e responsabilização, gestão e clínica farmacêutica como componentes e o uso racional de medicamentos como o propósito. O modelo proposto direciona o acesso para o serviço de dispensação e demanda a reorientação de rotinas, instrumentos e práticas.

    Medicinal baits are distributed to manage zoonotic diseases, including raccoon (Procyon lotor) rabies, but efficient distribution strategies are needed for suburban environments. We developed an automated dispenser that transfers fishmeal polymer baits at user-specified intervals from a magazine to a receptacle fitted with a filter that exploits raccoon dexterity to limit consumption by nontarget species. We introduce the concept of automated dispensers and describe bait removal success rates for raccoons versus nontarget species. We monitored visitation with remote cameras after deploying a dispenser, programmed to present two baits per night, in three disjunct forest patches in northwest Indiana. Raccoons removed 72% of baits; nontarget, white-footed mice (Peromyscus leucopus) removed 11%; Virginia opossums (Didelphis virginiana) removed 9%. Bait removal success varied significantly between raccoons (76%) and opossums (21%), improving bait delivery specificity relative to hand baiting. Accumulation of baits in receptacles resulted in excess (more than one) bait consumption (39% of baits consumed by raccoons were excess), suggesting design improvements are needed to present additional baits only after previous baits have been consumed. Automated dispensers successfully sustained bait availability throughout the operational period. Subsequent research is needed to determine whether a sustained availability of baits achieved with automated dispensers is more effective for the treatment of raccoons in suburban environments than traditional distribution methods.

    To evaluate the effects of improved water location visibility and water dispenser position on the soda dispenser on undergraduate students' beverage choices. Two focus groups with pilot intervention surveys before and after, adding a small sign above the soda dispensers' water button for 6 weeks in a large US university's all-you-can-eat, prepaid dining hall (measured with chi-square tests and logistic and ordinal logistic regression). Focus groups included 15 students. Survey participants included 357 students before and 301 after the intervention. After the intervention, more students reported ever having drunk water with the meal (66.4% to 77.0%; P = .003) and water consumption frequency increased (P = .005). Postintervention, the odds of drinking water increased by 1.57. Preference for other drinks was the main reason for not drinking water. A total of 59% of students had ever changed their preference from water to soda. The clear indication of the water's location increased students' reported water consumption. Further investigation is needed into how a non-independent water dispenser influences students' beverage choice. Clearly labeled, independent water dispensers are recommended.

    Mail-service pharmacies offer consumers the convenience of prescriptions filled with a 90-day supply of medication. Unlike mail-service pharmacies, retail pharmacies traditionally dispensed maintenance medication prescriptions with a 30-day supply. However, the retail landscape changed in May 2008 with Walmart's announcement of an extension of its $4 Prescription Program to include 90-day-supply prescriptions. To evaluate recent changes in access to and use of 90-day-supply maintenance medications dispensed via retail pharmacy. As of the first quarter of 2007, the proportion of retail-dispensed maintenance medications with a 90-day supply (compared with all maintenance prescriptions dispensed) among Medicare Part D plans, self-insured employers, and private health plans was 5.1%, 5.1%, and 5.0%, respectively. As of December 2009, this ratio had risen to 8.0% for Medicare plans and 8.1% for commercial health plans; the ratio among employers had risen more modestly to 6.1%. Of particular interest and importance, the proportion increased similarly for brand and for generic medications. There has been substantial growth in 90-day prescriptions dispensed via retail pharmacy, a trend that is likely to continue as more insurance providers adopt compatible benefit designs. It is important to continue monitoring these trends and to identify opportunities to rigorously evaluate their impact on medication adherence and healthcare costs.

    Full Text Available ABSTRACT Objective: Reassess the diagnosis of Alzheimer's Disease (AD in patients treated with anti-cholinesterases dispensed by High Cost Drug stores (Exceptional Drugs Program. Methods: A prospective study to reassess the diagnosis of probable Alzheimer's Disease was conducted (AD. The patients were submitted to the protocol of dementia investigation at the Neurogeriatric Outpatient Clinic of the Teaching Hospital de Base de São José do Rio Preto. Groups were classified using the criteria of the National Institute of Neurologic and Communicative Diseases and Vascular Cerebral Accident and Alzheimer Disease Related Association (NINCDS-ADRDA. The study was completed by applying the Disability Assessment for Dementia (DAD. The significance level was set at 5%. Results: 106 patients participated, selected randomly from a group of 390 patients contacted when receiving their medication at the High Cost Drug store. Two groups were formed: the first, containing 52 patients who fulfilled criteria for AD (FC Group; and a second, with 54 patients not fulfilling criteria (NFC. The FC Group had older age, worse performance on the Mini-Mental State Exam (MMSE and poorer performance on the DAD. Also, treatment time was longer and drugs doses higher in the FC Group. Conclusion: Study results showed a high number of patients using anti-cholinesterases that did not fulfill the diagnosis criteria for probable AD. Comparison of the two groups revealed different behavior between them, corroborating the hypothesis of inadequate inclusion of the NFC Group patients in the Exceptional Drugs Program.

    Full Text Available The aim of this study was to explore and describe the perceptions of nurses regarding the implementation of the occupation-specific dispensation (OSD in a selected nursing college in Limpopo province. A qualitative approach was used with a purposive sampling method for the selection of 12 voluntary participants who had worked for more than five years and been subjected to the implementation of OSD. In-depth interviews were conducted and data analysed according to Tesch's method. The perceptions of nurse educators were shared through participants' responses to a central research question. Participants expressed different responses, both positive and negative. The findings of this study demonstrated: high expectations, unfair treatment in relation to the implementation, and reactions to introduction of OSD. Participants also identified envisaged ways of improving the situation through the identification of ways to correct the problems. This study recommended that management ensure that nurse educators' remuneration packages are competitive with those of similar professions in the clinical setting. Recognition of nurse educators' additional qualifications, long-service experiences and rural allowance reviews in nursing education should be taken into consideration urgently.

    Full Text Available Rowan Yemm, Christabel Jones, Tryphosa Mitoko Cardiff University School of Pharmacy and Pharmaceutical Sciences, Cardiff University, Cardiff, Wales, UK Introduction: In 2015, the UK health secretary made public an intention to include the value of medicines costing over £20 on dispensing labels as an attempt to reduce wastage attributable to patient behavior. However, there is a lack of evidence investigating the potential effect or feasibility of this proposal, and concerns have been raised that it may introduce new problems in vulnerable groups. This pilot study aimed to gather views of the Welsh general public on this subject.Methods: Six focus groups from within key population groups were conducted. A snowball sampling strategy was employed with participants recruited via a neutral gatekeeper. Focus groups session were audio recorded and transcribed verbatim and iterative thematic analysis was used to identify emergent themes.Results: Six focus groups were conducted. Three key themes were identified: “influence of cost” – whereby participants expressed concern about cost linking to their perceived value, guilt for needing prescribed medication and irrelevance of cost if the medication was considered necessary; “knowledge is power” – whereby participants expressed a desire to know more about their medicines and engage with health care professionals about them, and felt information on dispensing labels alone would be insufficient to support this and “blame the system” – whereby participants felt responsibility for wastage should be shared by both system and patient and identified existing wasteful practices such as inappropriate prescribing, ordering and disposal of returned medicines.Conclusion: Findings were largely consistent with criticisms publicized by professional bodies that introducing cost may serve to make patients feel guilty or unworthy rather than encourage them to use their medicines appropriately.

    In nuclear medicine, radiopharmaceuticals are usually administered in unit doses partitioned from multi-dose vials. The partitioning typically takes place in a radiopharmacy, depending on local practice. Automatic, as opposed to manual, partitioning and administration should reduce radiation exposure of the personnel involved, improve the accuracy of the administration and mitigate contamination. This study set out to verify and validate the {sup 18}F-fluorodeoxyglucose (FDG) administration procedure performed using Intego trademark (MEDRAD, Inc., Warrendale, PA, USA), a combined dispenser and injector system. We considered maintenance of sterility and the system's potential to improve, with respect to the manual procedure, the accuracy of net administered {sup 18}F-FDG radioactivity in patients and the radiation protection of operators. A media-fill procedure was used to assess whether sterility is maintained during use of the Intego trademark system. Simulating a typical working day's setup and use of the system, we investigated the accuracy of the net administered {sup 18}F-FDG activity obtained with Intego trademark versus the manual dose delivery system. We also measured personnel radiation exposure during use of Intego trademark and during manual administration and recorded and compared environmental doses in the two conditions. The radiopharmaceutical remained sterile in all the tests performed. The accuracy of the net {sup 18}F-FDG activity delivered to the patients was found to be within 3 % points, as required by European Association of Nuclear Medicine (EANM) guidelines on {sup 18}F-FDG imaging procedures. With Intego trademark, the residual radioactivity in the tubing was 0.20 MBq, corresponding to approximately 0.07 % of the mean activity delivered.

    The mitochondrial alternative oxidase is an important enzyme that allows respiratory activity and the functioning of the Krebs cycle upon disturbance of the respiration chain. It works as a security valve in transferring excessive electrons to oxygen, thereby preventing potential damage by the generation of harmful radicals. A clear biological function, besides the stress response, has so far convincingly only been shown for plants that use the alternative oxidase to generate heat to distribute volatiles. In fungi it was described that the alternative oxidase is needed for pathogenicity. Here, we investigate expression and function of the alternative oxidase at different stages of the life cycle of the corn pathogen Ustilago maydis (Aox1). Interestingly, expression of Aox1 is specifically induced during the stationary phase suggesting a role at high cell density when nutrients become limiting. Studying deletion strains as well as overexpressing strains revealed that Aox1 is dispensable for normal growth, for cell morphology, for response to temperature stress as well as for filamentous growth and plant pathogenicity. However, during conditions eliciting respiratory stress yeast-like growth as well as hyphal growth is strongly affected. We conclude that Aox1 is dispensable for the normal biology of the fungus but specifically needed to cope with respiratory stress.

    To estimate the use of cardiovascular medicines and its distribution by age and sex. Observational study. Region of Murcia. Daily doses of cardiovascular drugs prescribed and dispensed in all the pharmacies of the Region per 1,000 inhabitants-day (DHD). A comparison was made of consumption rates (DHD) by age and sex. The probability of receiving antiplatelet drugs increases with age, with the proportion of men being higher. The use of beta-blockers and angiotensin II increases with age up to 79 years, with an increased consumption in men up to 65 years. The probability of receiving treatment with calcium channel blockers, ACE inhibitors, or statins, linearly increases with age, and the proportion of men under treatment exceeds that of women in the early ages, tending to equalize beyond 80 years. This study shows that the cardiovascular disease prevention focuses on people aged 40 to 74 years. Access by women to cardiovascular therapy occurs with a delay of 3-5 years, depending on the treatment subgroup. Changes should be promoted to encourage rational and equitable access and use of the drugs. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    The single pellet reaching and grasping (SPG) task is widely used to study forelimb motor performance in rodents and to provide rehabilitation after neurological disorders. Nonetheless, the time necessary to train animals precludes its use in settings where high-intensity training is required. In the current study, we developed a novel high-intensity training protocol for the SPG task based on a motorized pellet dispenser and a dual-window enclosure. We tested the protocol in naive adult rats and found 1) an increase in the intensity of training without increasing the task time and without affecting the overall performance of the animals, 2) a reduction in the variability within and between experiments in comparison to manual SPG training, and 3) a reduction in the time required to conduct experiments. In summary, we developed and tested a novel protocol for SPG training that provides higher-intensity training while reducing the variability of results observed with other protocols.

    A method for filling alkali vapor cells with cesium from a dispensing paste is proposed and its compliance with miniature atomic clock applications is evaluated. The paste is an organic-inorganic composition of cesium molybdate, zirconium-aluminum powder, and a hybrid organic-inorganic binder. It is compatible with collective deposition processes such as micro-drop dispensing, which can be done under ambient atmosphere at the wafer-level. After deposition and sealing by anodic bonding, cesium is released from the consolidated paste through local heating with a high power laser. Linear absorption signals have been observed over one year in several cells, showing a stable atomic density. For further validation of this technology for clock applications, one cell has been implemented in a coherent population trapping clock setup to monitor its frequency stability. A fractional frequency aging rate around -4.4 × 10-12 per day has been observed, which is compliant with a clock frequency instability below 1 × 10-11 at one day integration time. This filling method can drastically reduce the cost and the complexity of alkali vapor cell fabrication.

    To understand the potential barriers, motivators and enablers in dispensing multifocal contact lenses (MFCL). Two focus group discussions were conducted to design questionnaires regarding the prescribing habits for multifocal contact lenses (MFCL). Questions on potential barriers and motivators were included. The questionnaires were distributed among 133 eye care practitioners across Mumbai, India. Practitioners fitting one or less patient per month with MFCL completed the survey describing potential barriers, while those who prescribed more MFCL's per month completed the survey describing enablers and motivators. Responses from 102 practitioners were received. Most common potential barriers in prescribing MFCL were increased chair time (75%), lack of readily available trials (69%) and limitation in power range (63%). Lack of awareness among patients (90%) was the most common barrier from patients' outlook. Professional satisfaction (88%) and better business proposition (82%) were observed as main motivators while availability of the trials (84%) and correct patient selection (82%) were the major enablers. Graduate Optometrists felt dispensing MFCL did not offer a good business proposition (p=0.02). Experienced practitioners were observed to be least motivated (p=0.01) and believed that their patients found these lenses expensive (p=0.02). To enhance the MFCL practice, barriers like lack of awareness and limitations in power range must be addressed. Trial lens availability may motivate practitioners to prescribe MFCL. Further probing is required to understand lack of motivation among experienced practitioners. Copyright © 2014 Spanish General Council of Optometry. Published by Elsevier Espana.

    Hospital pharmacists have been challenged to face the paradigm shift in their model of services in the 21st century in Taiwan. Patients are increasingly concerned about drug safety and medication errors. Because of the financial crisis of our national insurance bureau, pharmacists are required to care for more patients, use fewer resources, and work faster, better, and more efficiently than ever before while striving to enhance customer satisfaction and quality of care. Under these circumstances, patient safety needs to be a priority of pharmacists. According to a preliminary report on medication error announced by the nonofficial medication error reporting system, pharmacist dispensing error ranked second in the list of errors in Taiwan. In our drive to improve quality, reduce costs, and enhance financial performance, our department has tried the traditional quality-improvement strategy with varying degrees of success. We wanted to achieve a breakthrough result, hence we implemented Six-Sigma methodology. This program is the catalyst needed to combine quality, cost, and patient safety. This article describes our experience using Six-Sigma methodology to reduce dispensing error in our pharmacy department.

    This work presents performance advancements of dispenser printed composite thermoelectric materials and devices. Dispenser printed thick films allow for low-cost and scalable manufacturing of microscale energy harvesting devices. A maximum ZT value of 0.31 has been achieved for mechanically alloyed (MA) n-type Bi₂Te₃-epoxy composite films with 1 wt % Se cured at 350 °C. The enhancement of ZT is a result of increase in the electrical conductivity through the addition of Se, which ultimately lowers the sintering temperature (350 °C). A 62 single-leg thermoelectric generator (TEG) prototype with 5 mm ×700 μm × 120 μm printed element dimensions was fabricated on a custom designed polyimide substrate with thick metal contacts. The prototype device produced a power output of 25 μW at 0.23 mA current and 109 mV voltage for a temperature difference of 20 °C, which is sufficient for low power generation for autonomous microsystem applications.

    For quit-smoking clinic and its campaign, there was a need for pharmacists to investigate pediatric patient's parent consciousness to tobacco harm utilizing wait time in a pediatric dispensing pharmacy. In this research, we developed the questionnaire and quiz total system using the tablet for user interface, in which people can easily answer the questionnaire/quiz and quickly see the total results on the spot in order to enhance their consciousness to the tobacco harm. The system also provides their tobacco dependence level based on the questionnaire results and some advice for their health and dietary habits due to the tobacco dependence level. From a field trial with one hundred four examinees in the pediatric dispensing pharmacy, the user interface was useful compared to conventional questionnaire form. The system could enhance their consciousness to tobacco harm and make their beneficial use of waiting time in dispensing pharmacy. Some interesting suggestions for improvement and new services were also obtained.

    Clinicians who work in the postanesthesia care unit (PACU), operating room (OR), and intensive care unit (ICU) have a greater opportunity to cross-contaminate patients because of high workloads and frequent patient contact events. Much progress has been made to increase hand hygiene compliance with the introduction of alcohol-based wall, bedside, and pocket dispensers. The introduction of body-worn alcohol-based dispensers to anesthesia and ICU providers has been shown to decrease ICU hospital-acquired infections and ventilator-associated pneumonias, and decrease contamination of the anesthesia workplace. Body-worn alcohol-based dispensers are an improvement in ergonomics, especially for those working in high intensity areas. The unit worn on the belt or scrubs waist is readily accessible, can be activated with one hand, and can be a vital tool to close the gap for hand hygiene.

    Epiblast stem cells (EpiSCs), which are pluripotent cells isolated from early post-implantation mouse embryos (E5.5), show both similarities and differences compared to mouse embryonic stem cells (mESCs), isolated earlier from the inner cell mass (ICM) of the E3.5 embryo. Previously, we have observed that while chromatin is very dispersed in E3.5 ICM, compact chromatin domains and chromocentres appear in E5.5 epiblasts after embryo implantation. Given that the observed chromatin re-organization in E5.5 epiblasts coincides with an increase in DNA methylation, in this study, we aimed to examine the role of DNA methylation in chromatin re-organization during the in vitro conversion of ESCs to EpiSCs. The requirement for DNA methylation was determined by converting both wild-type and DNA methylation-deficient ESCs to EpiSCs, followed by structural analysis with electron spectroscopic imaging (ESI). We show that the chromatin re-organization which occurs in vivo can be re-capitulated in vitro during the ESC to EpiSC conversion. Indeed, after 7 days in EpiSC media, compact chromatin domains begin to appear throughout the nuclear volume, creating a chromatin organization similar to E5 epiblasts and embryo-derived EpiSCs. Our data demonstrate that DNA methylation is dispensable for this global chromatin re-organization but required for the compaction of pericentromeric chromatin into chromocentres.

    Full Text Available CD4 T cells acquire functional properties including cytokine production upon antigenic stimulation through the T cell receptor (TCR and differentiate into T helper (Th cells. Th1 cells produce interferon (IFN-γ and Th2 cells produce interleukin (IL-4. Th1 and 2 cells utilize IFN-γ and IL-4 for further maturation and maintenance, respectively. Promyelocytic leukemia zinc finger (PLZF-expressing invariant natural killer T (iNKT cells develop in the thymus and acquire functional ability to produce IL-4 and IFN-γ in the thymus in the absence of antigenic stimulation. In response to antigenic stimulation, iNKT cells rapidly produce IFN-γ and IL-4. However, it is still unknown as to whether iNKT cells require these cytokines for maturation or survival in vivo. In this study, using IL-4- and IL-4 receptor- (IL-4R deficient mice, we demonstrate that IL-4 as well as IL-4R expression is dispensable for the development, function and maintenance of iNKT cells.

    Flexible manufacturing technologies for solid oral dosage forms with a continuous adjustability of the manufactured dose strength are of interest for applications in personalized medicine. This study explored the feasibility of using microvalve technology for the manufacturing of different solid oral dosage form concepts. Hard gelatin capsules filled with excipients, placebo tablets, and polymer films, placed in hard gelatin capsules after drying, were considered as substrates. For each concept, a basic understanding of relevant formulation parameters and their impact on dissolution behavior has been established. Suitable matrix formers, present either on the substrate or directly in the drug nanosuspension, proved to be essential to prevent nanoparticle agglomeration of the drug nanoparticles and to ensure a fast dissolution behavior. Furthermore, convection and radiation drying methods were investigated for the fast drying of drug nanosuspensions dispensed onto polymer films, which were then placed in hard gelatin capsules. Changes in morphology and in drug and matrix former distribution were observed for increasing drying intensity. However, even fast drying times below 1 min could be realized, while maintaining the nanoparticulate drug structure and a good dissolution behavior.

    In addition to β-cells, pancreatic islets contain α- and δ-cells, which respectively produce glucagon and somatostatin. The reprogramming of these two endocrine cell types into insulin producers, as observed after a massive β-cell ablation in mice, may help restoring a functional β-cell mass in type 1 diabetes. Yet, the spontaneous α-to-β and δ-to-β conversion processes are relatively inefficient in adult animals and the underlying epigenetic mechanisms remain unclear. Several studies indicate that the conserved chromatin modifiers DNA methyltransferase 1 (Dnmt1) and Enhancer of zeste homolog 2 (Ezh2) are important for pancreas development and restrict islet cell plasticity. Here, to investigate the role of these two enzymes in α- and δ-cell development and fate maintenance, we genetically inactivated them in each of these two cell types. We found that loss of Dnmt1 does not enhance the conversion of α- or δ-cells toward a β-like fate. In addition, while Dnmt1 was dispensable for the development of these two cell types, we noticed a gradual loss of α-, but not δ-cells in adult mice. Finally, we found that Ezh2 inactivation does not enhance α-cell plasticity, and, contrary to what is observed in β-cells, does not impair α-cell proliferation. Our results indicate that both Dnmt1 and Ezh2 play distinct roles in the different islet cell types. Copyright © 2017 Elsevier Ltd. All rights reserved.

  17. IL-22 is mainly produced by IFNγ-secreting cells but is dispensable for host protection against Mycobacterium tuberculosis infection.

    Directory of Open Access Journals (Sweden)

    Jochen Behrends

    Full Text Available Anti-inflammatory treatment of autoimmune diseases is associated with an increased risk of reactivation tuberculosis (TB. Besides interleukin (IL-17A, IL-22 represents a classical T helper (TH17 cytokine and shares similar pathological effects in inflammatory diseases such as psoriasis or arthritis. Whereas IL-17A supports protective immune responses during mycobacterial infections, the role of IL-22 after infection with Mycobacterium tuberculosis (Mtb is yet poorly characterized. Therefore, we here characterize the cell types producing IL-22 and the protective function of this cytokine during experimental TB in mice. Like IL-17A, IL-22 is expressed early after infection with Mtb in an IL-23-dependent manner. Surprisingly, the majority of IL-22-producing cells are not positive for IL-17A but have rather functional characteristics of interferon-gamma-producing TH1 cells. Although we found minor differences in the number of naive and central memory T cells as well as in the frequency of TH1 and polyfunctional T cells in mice deficient for IL-22, the absence of IL-22 does not affect the outcome of Mtb infection. Our study revealed that although produced by TH1 cells, IL-22 is dispensable for protective immune responses during TB. Therefore, targeting of IL-22 in inflammatory disease may represent a therapeutic approach that does not incur the danger of reactivation TB.

    A mating disruption approach using high densities of pheromone dispensers, has been recently proposed for codling moth, Cydia pomonella (L.), and oriental fruit moth, Cydia molesta (Busck.), (Lepidoptera Tortricidae), control. Ecodian Star dispensers, made of low-cost biodegradable material and easy to apply, were formulated with 10 mg of codlemone (E8,E10-12OH) and 10 mg of grapamone (Z8-12OH) and placed at a rate of 1,400-2,000 dispensers/ha. The pheromone release rates from new and field aged dispensers were evaluated by hexane extraction of the residual attractant (indirectly) and gas-chromatographic analysis. The release rate of field-aged dispensers decreased over time with a good linearity; they released a significant amount of synthetic sex pheromones over the entire season. Dispensers elicited close-range approaches of codling moth males in wind tunnel irrespective of their age. Field trials carried out from 2003 to 2004 confirmed the efficacy of Ecodian Star dispensers for codling moth and oriental fruit moth control, regardless the size of the treated area. Our results demonstrate that Ecodian dispensers achieved a good level of activity and longevity over the season. The potential of this strategy for the control of the moths is discussed.

    Directory of Open Access Journals (Sweden)

    Jang Eun Lee

    Full Text Available Differentiation of T cells is closely associated with dynamic changes in nutrient and energy metabolism. However, the extent to which specific metabolic pathways and molecular components are determinative of CD8+ T cell fate remains unclear. It has been previously established in various tissues that acetyl CoA carboxylase 2 (ACC2 regulates fatty acid oxidation (FAO by inhibiting carnitine palmitoyltransferase 1 (CPT1, a rate-limiting enzyme of FAO in mitochondria. Here, we explore the cell-intrinsic role of ACC2 in T cell immunity in response to infections. We report here that ACC2 deficiency results in a marginal increase of cellular FAO in CD8+ T cells, but does not appear to influence antigen-specific effector and memory CD8+ T cell responses during infection with listeria or lymphocytic choriomeningitis virus. These results suggest that ACC2 is dispensable for CD8+ T cell responses.

    At the request of the U.S. Department of Energy Fuel Cell Technologies Office (FCTO), the National Renewable Energy Laboratory commissioned an independent review of hydrogen compression, storage, and dispensing (CSD) for pipeline delivery of hydrogen and forecourt hydrogen production. The panel was asked to address the (1) cost calculation methodology, (2) current cost/technical status, (3) feasibility of achieving the FCTO's 2020 CSD levelized cost targets, and to (4) suggest research areas that will help the FCTO reach its targets. As the panel neared the completion of these tasks, it was also asked to evaluate CSD costs for the delivery of hydrogen by high-pressure tube trailer. This report details these findings.

    Cilia are cellular projections that assemble on centriole-derived basal bodies. While cilia assembly is absolutely dependent on centrioles, it is not known to what extent they contribute to downstream events. The nematode C. elegans provides a unique opportunity to address this question, as centrioles do not persist at the base of mature cilia. Using fluorescence microscopy and electron tomography, we find that centrioles degenerate early during ciliogenesis. The transition zone and axoneme are not completely formed at this time, indicating that cilia maturation does not depend on intact centrioles. The hydrolethalus syndrome protein HYLS-1 is the only centriolar protein known to remain at the base of mature cilia and is required for intraflagellar transport trafficking. Surprisingly, targeted degradation of HYLS-1 after initiation of ciliogenesis does not affect ciliary structures. Taken together, our results indicate that while centrioles are essential to initiate cilia formation, they are dispensable for cilia maturation and maintenance. © 2017 Serwas et al.

    In the paper, we present a single-step lithography system whereby the robotically controlled micro-extrusion of resist adhesive onto a substrate surface to directly create resist adhesive patterns of interest. This system is modified from a robotic adhesive dispenser by shrinking the aperture of the nozzle to a few micrometers aiming to realize patterns at microscale. From experimental investigation, it is found that working factors including writing speed, working time, and applied pressure can be adopted to conveniently regulate the feature size (the width of the line features and the diameter of the dot features). To test its functionality, the system was used to pattern line features on silicon dioxide (SiO2) and generate an array of square-like silicon microstructure by combining with wet etching. It provides a simple and flexible alternative tool to facilitate the development of microfabrication.

    Although the elementary unit of biology is the cell, high-throughput methods for the microscale manipulation of cells and reagents are limited. The existing options either are slow, lack single-cell specificity, or use fluid volumes out of scale with those of cells. Here we present printed droplet microfluidics, a technology to dispense picoliter droplets and cells with deterministic control. The core technology is a fluorescence-activated droplet sorter coupled to a specialized substrate that together act as a picoliter droplet and single-cell printer, enabling high-throughput generation of intricate arrays of droplets, cells, and microparticles. Printed droplet microfluidics provides a programmable and robust technology to construct arrays of defined cell and reagent combinations and to integrate multiple measurement modalities together in a single assay.

    We examined the content protection characteristics of the PID (Pouch in Dispenser) when it was used in the usual manner and when it was polluted artificially. When the PID was used in the usual manner, the nozzle was opened, and experiments were carried out with and without air-blowing. The invasion of bacteria into the PID was not detected. Also, no bacteria were detected in the material poured from the nozzle of the PID. When 3 strains of bacteria suspensions were intentionally smeared on the nozzle of the PID, invasion of bacteria was observed. When the PID was wiped with a dirty cloth, no invasion of bacteria into the PID was detected. It may be necessary to label the PID with the instruction that the nozzle should not be touched. The effected of changes in the water activity and pH, and the preservatives used, may also need to be considered, depending on the contents in the PID.

    Non-destructive isolation of single-cells has become an important need for many biology research laboratories; however, there is a lack of easily employed and inexpensive tools. Here, we present a single-particle sample delivery approach fabricated from simple, economical components that may address this need. In this, we employ unique flow and timing strategies to bridge the significant force and length scale differences inherent in transitioning from single particle isolation to delivery. Demonstrating this approach, we use an optical trap to isolate individual microparticles and red blood cells that are dispensed within separate 50 μl droplets off a microfluidic chip for collection into microscope slides or microtiter plates.

    The ATM kinase plays critical roles in the response to DNA double-strand breaks, and can also be activated by prolonged DNA replication blocks. It has recently been proposed that replication stress-dependent ATM activation is mediated by ASCIZ (also known as ATMIN, ZNF822), an essential developmental transcription factor. In contrast, we show here that ATM activation, and phosphorylation of its substrates KAP1, p53 and H2AX in response to the replication blocking agent aphidicolin was unaffected in both immortalized and primary ASCIZ/ATMIN-deficient murine embryonic fibroblasts compared to control cells. Similar results were also obtained in human ASCIZ/ATMIN-deleted lymphoma cells. The results demonstrate that ASCIZ/ATMIN is dispensable for ATM activation, and contradict the previously reported dependence of ATM on ASCIZ/ATMIN. Copyright © 2017 The Authors.

    Automation has long been awaited in parenteral drug dispensing. Pharmacists can benefit much in theory from a good automated device to handle the hazardous drugs used in chemotherapy. This paper describes the performance of the first chemotherapy-dispensing robot in the oncology pharmacy of a 2500-bed medical center. The objective of this paper is two-fold: (1) to assess the robot's performance in terms of its success rate and to summarize the causes of failure, and (2) to find out if the robot can decrease the full-time equivalents (FTEs) of the oncology pharmacy. We used the computer-generated log from the first week of May 2010 to that of July 2010, supplemented with the pharmacists' notes on the causes of failure, to determine the success rate and to analyze the incidences of failure. We also assessed the FTEs before and after implementing the robot. Data showed that the success rate rose slowly from 76.8% to 95.3% over the 2-month recording period. The major mechanical problems encountered were air, clamping, and waste bin problems. Manual errors, such as loading wrong drugs or syringes, also caused failures. In terms of manpower saving, CytoCare failed to decrease the number of FTE pharmacists/technicians in our oncology pharmacy practice. We conclude that even though CytoCare could ease the risk of chemotherapy exposure and increase the precision of dosing, it was not able to improve the FTE pharmacists/technicians in our hospital.

  14. BAZ1B is dispensable for H2AX phosphorylation on Tyrosine 142 during spermatogenesis

    Directory of Open Access Journals (Sweden)

    Tyler J. Broering

    2015-07-01

    Full Text Available Meiosis is precisely regulated by the factors involved in DNA damage response in somatic cells. Among them, phosphorylation of H2AX on Serine 139 (γH2AX is an essential signal for the silencing of unsynapsed sex chromosomes during male meiosis. However, it remains unknown how adjacent H2AX phosphorylation on Tyrosine 142 (pTyr142 is regulated in meiosis. Here we investigate the meiotic functions of BAZ1B (WSTF, the only known Tyr142 kinase in somatic cells, using mice possessing a conditional deletion of BAZ1B. Although BAZ1B deletion causes ectopic γH2AX signals on synapsed autosomes during the early pachytene stage, BAZ1B is dispensable for fertility and critical events during spermatogenesis. BAZ1B deletion does not alter events on unsynapsed axes and pericentric heterochromatin formation. Furthermore, BAZ1B is dispensable for localization of the ATP-dependent chromatin remodeling protein SMARCA5 (SNF2h during spermatogenesis despite the complex formation between BAZ1B and SMARCA5, known as the WICH complex, in somatic cells. Notably, pTyr142 is regulated independently of BAZ1B and is dephosphorylated on the sex chromosomes during meiosis in contrast with the presence of adjacent γH2AX. Dephosphorylation of pTyr142 is regulated by MDC1, a binding partner of γH2AX. These results reveal the distinct regulation of two adjacent phosphorylation sites of H2AX during meiosis, and suggest that another kinase mediates Tyr142 phosphorylation.

    Full Text Available Abstract Background As a result of the previous part of this trial, many patients with cardiovascular disease were expected to receive a statin for the first time. In order to provide these patients with comprehensive information on statins, as recommended by professional guidance, education at first and second dispensing of statins had to be implemented. This study was designed to assess the effectiveness of an intensive implementation program targeted at pharmacy project assistants on the frequency of providing education at first dispensing (EAFD and education at second dispensing (EASD of statins in community pharmacies. Methods The participating community pharmacies were clustered on the basis of local collaboration, were numbered by a research assistant and subsequently an independent statistician performed a block randomization, in which the cluster size (number of pharmacies in each cluster was balanced. The pharmacies in the control group received a written manual on the implementation of EAFD and EASD; the pharmacies in the intervention group received intensive support for the implementation. The impact of the intensive implementation program on the implementation process and on the primary outcomes was examined in a random coefficient logistic regression model, which took into account that patients were grouped within pharmacy clusters. Results Of the 37 pharmacies in the intervention group, 17 pharmacies (50% provided EAFD and 12 pharmacies (35.3% provided EASD compared to 14 pharmacies (45.2%, P = 0.715 and 12 pharmacies (38.7%, P = 0.899, respectively, of the 34 pharmacies in the control group. In the intervention group a total of 72 of 469 new statin users (15.4% received education and 49 of 393 patients with a second statin prescription (12.5% compared to 78 of 402 new users (19.4%, P = 0.944 and 35 of 342 patients with a second prescription (10.2%, P = 0.579 in the control group.

    Hospital visitors' hand hygiene (HH) is an important aspect of preventing health care-associated infections, but little is known about visitors' use of alcohol-based hand sanitizers (AHS). The study aim was to examine if use of AHS is influenced by visitor characteristics and the location of AHS within the lobby of a large hospital. An observational study was conducted with AHS placed in 3 different locations. The data included visitor characteristics and if AHS were used. The results suggest that visitors are 5.28 times (95% confidence interval [CI], 3.68-7.82) more likely to use AHS when dispensers are located in the middle of the lobby with limited landmarks or barriers, 1.35 times more likely to use the AHS in the afternoon compared with the morning, or when they are younger visitors (adjusted odds ratio, 1.47; 95% CI, 1.09-1.97). Individuals in a group are more likely (adjusted odds ratio, 1.39; 95% CI, 1.06-1.84) to use AHS. In addition to location, time of day, and age, there is a group effect that results in visitors being more likely to use AHS when in a group. The increased use related to groups may serve as a mechanism to encourage visitor HH. The results suggest future research opportunities to investigate the effect of group dynamics and social pressure on visitor AHS use and to identify strategies for improving visitor HH.

    Pakistan spends 0.7% of its gross domestic product on health. The public sector health-care system provides services to 22% of population thus paving the way for a dominant private sector. Patients in Pakistan mostly pay their medical expenses directly, and 64% of the health expenditures are borne by the household. Expenditure on medicine constitutes 43% of the total household expenditure. A quantitative cross-sectional study was conducted in Karachi, Pakistan, for a month. It was aimed at gathering response from different pharmacies to understand the brand versus generic dispensing trend of ciprofloxacin 500 mg, levofloxacin 500 mg, and moxifloxacin 400 mg oral dosage forms. The study employed convenience sampling and used a survey checklist. The data gathered was entered in SPSS version 22. The mean price per tablet for ciprofloxacin brand and generic was reported at Pakistani Rupees (PKR) 48.44 and PKR 26.85, respectively. The trend for dispensing ciprofloxacin highlighted a split in the market between brand (51%) and generic (49%). For levofloxacin brand and generic, the price per tablet was reported at PKR 36.50 and PKR 36.15 respectively, and despite same price, the market was dominated by generic levofloxacin (92%). Due to a price difference between brand and generic moxifloxacin, i.e., PKR 129.44 and PKR 71.91, respectively, the market was mostly occupied by the generic form (75%). Pricing mechanism must be revisited, and the authorities should take stern actions against any illegitimate price hike. The surging burden of drug expenditure on poorer sections of the society must be addressed by the government on an urgent basis.

  19. Usefulness of pharmacy dispensing records in the evaluation of adherence to antiretroviral therapy in Brazilian children and adolescents

    Full Text Available INTRODUCTION: Adherence, which is crucial to the success of antiretroviral therapy (HAART, is currently a major challenge in the care of children and adolescents living with HIV/AIDS. OBJECTIVE: To evaluate the prevalence of nonadherence to HAART using complementary instruments in a cohort of children and adolescents with HIV/AIDS followed in a reference service in Campinas, Brazil. METHODS: The level of adherence of 108 patients and caregivers was evaluated by an adapted standardized questionnaire and pharmacy dispensing records (PDR. Non-adherence was defined as a drug intake lower than 95% (on 24-hour or seven-day questionnaires, or as an interval of 38 days or more for pharmacy refills. The association between adherence and clinical, immunological, virological, and psychosocial characteristics was assessed by multivariate analysis. RESULTS: Non-adherence prevalence varied from 11.1% (non-adherent in three instruments, 15.8% (24-hour self-report, 27.8% (seven-day self-report, 45.4% (PDR, and 56.3% (at least one of the outcomes. 24-hour and seven-day self-reports, when compared to PDR, showed low sensitivity (29% and 43%, respectively but high specificity (95% and 85%, respectively. In multivariate analysis, medication intolerance, difficulty of administration by caregiver, HAART intake by the patient, lower socioeconomical class, lack of virological control, missed appointments in the past six months, and lack of religious practice by caregiver were significantly associated with non-adherence. CONCLUSION: A high prevalence of HAART non-adherence was observed in the study population, and PDR was the most sensitive of the tested instruments. The instruments employed were complementary in the identification of non-adherence.

  20. Signaling through IL-17C/IL-17RE is dispensable for immunity to systemic, oral and cutaneous candidiasis.

    Candida albicans is a commensal fungal microbe of the human orogastrointestinal tract and skin. C. albicans causes multiple forms of disease in immunocompromised patients, including oral, vaginal, dermal and disseminated candidiasis. The cytokine IL-17 (IL-17A) and its receptor subunits, IL-17RA and IL-17RC, are required for protection to most forms of candidiasis. The importance of the IL-17R pathway has been observed not only in knockout mouse models, but also in humans with rare genetic mutations that impact generation of Th17 cells or the IL-17 signaling pathway, including Hyper-IgE Syndrome (STAT3 or TYK2 mutations) or IL17RA or ACT1 gene deficiency. The IL-17 family of cytokines is a distinct subclass of cytokines with unique structural and signaling properties. IL-17A is the best-characterized member of the IL-17 family to date, but far less is known about other IL-17-related cytokines. In this study, we sought to determine the role of a related IL-17 cytokine, IL-17C, in protection against oral, dermal and disseminated forms of C. albicans infection. IL-17C signals through a heterodimeric receptor composed of the IL-17RA and IL-17RE subunits. We observed that IL-17C mRNA was induced following oral C. albicans infection. However, mice lacking IL-17C or IL-17RE cleared C. albicans infections in the oral mucosa, skin and bloodstream at rates similar to WT littermate controls. Moreover, these mice demonstrated similar gene transcription profiles and recovery kinetics as WT animals. These findings indicate that IL-17C and IL-17RE are dispensable for immunity to the forms of candidiasis evaluated, and illustrate a surprisingly limited specificity of the IL-17 family of cytokines with respect to systemic, oral and cutaneous Candida infections.

  1. A randomized-controlled trial with a Canadian electronic pill dispenser used to measure and improve medication adherence in patients with schizophrenia

    Full Text Available Objective: Medication adherence is extremely important in preventing relapse and lowering symptoms in schizophrenic patients. However, estimates show that nearly half of these patients have poor adherence. The Brief Adherence Rating Scale (BARS seems to be the most reliable tool assessing adherence in schizophrenia and shows that the antipsychotic adherence ratio (AAR is about 49.5 % in schizophrenia. The aim of the study was to test if an electronic pill dispenser named DoPill® improved AAR of schizophrenic patients. Furthermore, we compared AAR obtained by the DoPill® and the BARS, in order to verify whether the DoPill® provides reliable assessment of medication adherence. Methods: The DoPill® is a smart pill dispenser that beeps and flashes at the appropriate time of the day. Each of its 28 compartments is covered by a plastic lamina that, when taken off, sends a signal to the pharmacist. Patients were randomized to the DoPill® or Treatment As Usual group (TAU for six weeks. The BARS was used as a reference measure. Results: Forty-six percent of patients were deemed to be non-adherent with antipsychotic medication. The mean AAR was 67 % after six weeks. DoPill® recorded better AAR than some of those found in the literature and were lower than the BARS estimate we found. Conclusion: These results suggest that DoPill® is a valid tool that provides more reliable and objective data for the clinician about their patient’s adherence, than existing assessment tools like the BARS. Furthermore, the device may help patients successfully manage their medication regimen.

    This paper presents a spheroid chip in which three-dimensional (3D) tumor spheroids are not only formed by gravity-driven cell aggregation but also cultured at the perfusion rates controlled by balanced droplet dispensing without fluidic pumps. The previous spheroid chips require additional off-chip processes of spheroid formation and extraction as well as bulky components of fluidic pumps. However, the present spheroid chip, where autonomous medium droplet dispensers are integrated on a well array, achieves the on-chip 3D tumor spheroid formation and perfusion culture using simple structure without bulky fluidic pumps. In the experimental study, we demonstrated that the spheroid chip successfully forms 3D tumor spheroids in the wide diameter range of 220 μm-3.2 mm (uniformity > 90%) using H358, H23, and A549 non-small cell lung cancer cells. At the pump-less perfusion culture (Q = 0.1-0.3 μl/min) of spheroids, the number of H358 cells in the spheroid increased up to 50% from the static culture (Q = 0 μl/min) and the viability of the cultured cells also increased about 10%. Therefore, we experimentally verified that the perfusion environment created by the spheroid chip offers a favourable condition to the spheroids with high increase rate and viability. The present chip achieves on-chip 3D tumor spheroid formation and pump-less perfusion culture with simple structure, thereby exhibiting potential for use in integrated in-vivo-like cell culture systems.

    The navel orangeworm, Amyelois transitella (Walker) (Lepidoptera: Pyralidae), is a key pest of almonds and pistachios and is sometimes controlled using mating disruption as part of a program of integrated management. The formulation used has a single, nonattractive compound [(11Z,13Z)-hexadecadienal] as the active ingredient that is emitted from timed aerosol dispensers. This study compared this nonattractive, single-compound formulation with two aerosol formulations also containing two additional compounds [(11Z,13Z)-hexadecadien-1-ol and (3Z,6Z,9Z,12Z,15Z)-tricosapentaene] that are found in the pheromone glands, and that in combination with the aldehyde are attractive in wind-tunnel and field-attraction trials. An experiment in pistachios found 97% to 99% suppression of males captured in female-baited traps and 82-93% suppression of mating in sentinel females. Both assays revealed a trend to greater suppression by the more complete pheromone formulations. In almonds, where the abundance of navel orangeworm was lower, all three formulations suppressed males captured in traps and mating in sentinel females by >99%. Each of the formulations significantly reduced damage to Nonpareil almonds. In almonds, there were no significant differences among the formulations in disruption of sexual communication or in damage. These findings suggest that it may be possible to make mating disruption more cost-effective and to achieve higher levels of mating disruption by using attractive aerosol formulations to reduce the number of dispenser per ha. Such a formulation, however, would be more expensive to register in the United States than pheromones meeting the definition of straight-chain lepidopteran pheromone, including the currently used aldehyde-only formulation.

    Medication adherence is extremely important in preventing relapse and lowering symptoms in schizophrenic patients. However, estimates show that nearly half of these patients have poor adherence. The Brief Adherence Rating Scale (BARS) seems to be the most reliable tool assessing adherence in schizophrenia and shows that the antipsychotic adherence ratio (AAR) is about 49.5% in schizophrenia. The aim of the study was to test if an electronic pill dispenser named DoPill(®) improved AAR of schizophrenic patients. Furthermore, we compared AAR obtained by the DoPill(®) and the BARS, in order to verify whether the DoPill(®) provides reliable assessment of medication adherence. The DoPill(®) is a smart pill dispenser that beeps and flashes at the appropriate time of the day. Each of its 28 compartments is covered by a plastic lamina that, when taken off, sends a signal to the pharmacist. Patients were randomized to the DoPill(®) or treatment as usual groups for 6 weeks. The BARS was used as a reference measure. Forty-six percent of patients were deemed to be non-adherent with antipsychotic medication. The mean AAR was 67% after 6 weeks. DoPill(®) recorded better AAR than some of those found in the literature and were lower than the BARS estimate we found. These results suggest that DoPill(®) is a valid tool that provides more reliable and objective data for the clinician about their patient's adherence, than existing assessment tools like the BARS. Furthermore, the device may help patients successfully manage their medication regimen.

    alta prescripción pero muy bajo costo unitario en los servicios ambulatorios, a expensas de medicamentos de costo más alto y mayor eficacia terapéutica en la atención hospitalaria, que son los de mayor impacto en la economía de los hogares.OBJECTIVE: Measure and compare the percentage of prescriptions fully dispensed to persons with and without Popular Health Insurance (SPS in Spanish who use ambulatory and general hospital services associated with the Mexico State Health Services (SESA in Spanish, and taking into account insurance status. SESA user satisfaction was also measured with respect to access to medication. MATERIAL AND METHODS: Information for the study was taken from four surveys of SESA ambulatory and hospital units that included probabilistic samples with state representativity. Samples of ambulatory units were selected by stratification according to level of care and association to the SPS service network. RESULTS: The findings indicate that the percentage of prescriptions fully dispensed in SESA ambulatory units has improved, reaching approximately 90%, especially among those units offering services to persons affiliated with SPS. Nevertheless, these percentages continue to be lower than those of ambulatory units associated with social security institutions. Percentages of prescriptions fully dispensed have also improved in SESA hospital units, but continue to be relatively low. In nearly all states, as the percentage of prescriptions fully dispensed has increased, user satisfaction with access to medication has also improved. CONCLUSIONS: In 2006 more than 50% of the states had high levels of fully dispensed prescriptions among persons with SPS (>90%. The more significant problem exists among hospitals, since only 44% of users who received a prescription in SESA hospitals in 2006 had their prescriptions fully dispensed. This finding requires a review of SPS medication policies, which have favored highly prescribed low-cost medications at

  7. RNA-Interference Components Are Dispensable for Transcriptional Silencing of the Drosophila Bithorax-Complex

    2013-06-13

    Background:Beyond their role in post-transcriptional gene silencing, Dicer and Argonaute, two components of the RNA interference (RNAi) machinery, were shown to be involved in epigenetic regulation of centromeric heterochromatin and transcriptional gene silencing. In particular, RNAi mechanisms appear to play a role in repeat induced silencing and some aspects of Polycomb-mediated gene silencing. However, the functional interplay of RNAi mechanisms and Polycomb group (PcG) pathways at endogenous loci remains to be elucidated.Principal Findings:Here we show that the endogenous Dicer-2/Argonaute-2 RNAi pathway is dispensable for the PcG mediated silencing of the homeotic Bithorax Complex (BX-C). Although Dicer-2 depletion triggers mild transcriptional activation at Polycomb Response Elements (PREs), this does not induce transcriptional changes at PcG-repressed genes. Moreover, Dicer-2 is not needed to maintain global levels of methylation of lysine 27 of histone H3 and does not affect PRE-mediated higher order chromatin structures within the BX-C. Finally bioinformatic analysis, comparing published data sets of PcG targets with Argonaute-2-bound small RNAs reveals no enrichment of these small RNAs at promoter regions associated with PcG proteins.Conclusions:We conclude that the Dicer-2/Argonaute-2 RNAi pathway, despite its role in pairing sensitive gene silencing of transgenes, does not have a role in PcG dependent silencing of major homeotic gene cluster loci in Drosophila. © 2013 Cernilogar et al.

    A total weight of 1.23 kg (2.7 lb), a total volume of 1213 cu m (74 cu in), and an average power consumption of 5.5W was achieved in the advanced combined iodine dispenser/detector by integrating the detector with the iodine source, arranging all iodinator components within a compact package and lowering the parasitic power to the detector and electronics circuits. These achievements surpassed the design goals of 1.36 kg (3.0 lb), 1671 cu m (102 cu in) and 8W. The reliability and maintainability were improved by reducing the detector lamp power, using an interchangeable lamp concept, making the electronic circuit boards easily accessible, providing redundant water seals and improving the accessibility to the iodine accumulator for refilling. The system was designed to iodinate (to 5 ppm iodine) the fuel cell water generated during 27 seven-day orbiter missions (equivalent to 18,500 kg (40,700 lb) of water) before the unit must be recharged with iodine crystals.

  9. Fibroblast activation protein is dispensable in the anti-influenza immune response in mice.

    Directory of Open Access Journals (Sweden)

    Sioh-Yang Tan

    Full Text Available Fibroblast activation protein alpha (FAP is a unique dual peptidase of the S9B serine protease family, being capable of both dipeptidyl peptidase and endopeptidase activities. FAP is expressed at low level in healthy adult organs including the pancreas, cervix, uterus, submaxillary gland and the skin, and highly upregulated in embryogenesis, chronic inflammation and tissue remodelling. It is also expressed by cancer-associated stromal fibroblasts in more than 90% of epithelial tumours. FAP has enzymatic and non-enzymatic functions in the growth, immunosuppression, invasion and cell signalling of tumour cells. FAP deficient mice are fertile and viable with no gross abnormality, but little data exist on the role of FAP in the immune system. FAP is upregulated in association with microbial stimulation and chronic inflammation, but its function in infection remains unknown. We showed that major populations of immune cells including CD4+ and CD8+ T cells, B cells, dendritic cells and neutrophils are generated and maintained normally in FAP knockout mice. Upon intranasal challenge with influenza virus, FAP mRNA was increased in the lungs and lung-draining lymph nodes. Nonetheless, FAP deficient mice showed similar pathologic kinetics to wildtype controls, and were capable of supporting normal anti-influenza T and B cell responses. There was no evidence of compensatory upregulation of other DPP4 family members in influenza-infected FAP-deficient mice. FAP appears to be dispensable in anti-influenza adaptive immunity.

    wHospital is the result of an information technology research project, based on the utilization of a web based application for managing the hospital drugs dispensing. Part of wHospital back bone and its key distinguishing characteristic is the adoption of the digital signature system,initially deployed by the Government of Lombardia, a Northern Italy Region, throughout the distribution of smart cards to all the healthcare and hospital staffs. The developed system is a web-based application with a proposed Health Records Digital Signature (HReDS) handshake to comply with the national law and with the Joint Commission International Standards. The prototype application, for a single hospital Operative Unit (OU), has focused on data and process management, related to drug therapy. Following a multi-faceted selection process, the Infective Disease OU of the Hospital in Busto Arsizio, Lombardia, was chosen for the development and prototype implementation. The project lead time, from user requirement analysis to training and deployment was approximately 8 months. This paper highlights the applied project methodology, the system architecture, and the achieved preliminary results.

  11. The Histone Methyltransferase Activity of MLL1 Is Dispensable for Hematopoiesis and Leukemogenesis

    2014-05-01

    Full Text Available Despite correlations between histone methyltransferase (HMT activity and gene regulation, direct evidence that HMT activity is responsible for gene activation is sparse. We address the role of the HMT activity for MLL1, a histone H3 lysine 4 (H3K4 methyltransferase critical for maintaining hematopoietic stem cells (HSCs. Here, we show that the SET domain, and thus HMT activity of MLL1, is dispensable for maintaining HSCs and supporting leukemogenesis driven by the MLL-AF9 fusion oncoprotein. Upon Mll1 deletion, histone H4 lysine 16 (H4K16 acetylation is selectively depleted at MLL1 target genes in conjunction with reduced transcription. Surprisingly, inhibition of SIRT1 is sufficient to prevent the loss of H4K16 acetylation and the reduction in MLL1 target gene expression. Thus, recruited MOF activity, and not the intrinsic HMT activity of MLL1, is central for the maintenance of HSC target genes. In addition, this work reveals a role for SIRT1 in opposing MLL1 function.

  12. PGC-1α is dispensable for exercise-induced mitochondrial biogenesis in skeletal muscle.

    Directory of Open Access Journals (Sweden)

    Glenn C Rowe

    Full Text Available Exercise confers numerous health benefits, many of which are thought to stem from exercise-induced mitochondrial biogenesis (EIMB in skeletal muscle. The transcriptional coactivator PGC-1α, a potent regulator of metabolism in numerous tissues, is widely believed to be required for EIMB. We show here that this is not the case. Mice engineered to lack PGC-1α specifically in skeletal muscle (Myo-PGC-1αKO mice retained intact EIMB. The exercise capacity of these mice was comparable to littermate controls. Induction of metabolic genes after 2 weeks of in-cage voluntary wheel running was intact. Electron microscopy revealed no gross abnormalities in mitochondria, and the mitochondrial biogenic response to endurance exercise was as robust in Myo-PGC-1αKO mice as in wildtype mice. The induction of enzymatic activity of the electron transport chain by exercise was likewise unperturbed in Myo-PGC-1αKO mice. These data demonstrate that PGC-1α is dispensable for exercise-induced mitochondrial biogenesis in skeletal muscle, in sharp contrast to the prevalent assumption in the field.

    2017-03-01

    In a recent battle between reproductive rights and religious freedom, the U.S. Supreme Court, by a five to three vote, declined to review an appeal in Stormans, Inc v Wiesman, a case brought by a Washington state pharmacy owner and two pharmacists who held religious objections to emergency contraception. These petitioners brought a constitutional challenge to Washington state regulations that required pharmacies to dispense all lawfully prescribed pharmaceuticals. In 2015, the Ninth Circuit Court of Appeals ruled that these regulations did not violate the Constitution. The Ninth Circuit confirmed that pharmacies must comply with state regulations requiring access to drugs even if the owners of the pharmacies hold religious objections to the provision of certain types of drugs-here, emergency contraception. The pharmacy owners appealed this ruling, and in 2016, the Supreme Court declined to review the case, effectively leaving the lower court ruling in place. This article analyzes the Stormans case, the difference between it and a seemingly similar case regarding contraceptive access decided by the Supreme Court in 2014, the effects of the Stormans ruling on emergency contraception access in Washington state as well as the ruling's potential implications for public health.

    Given that uncorrected refractive error is a frequent cause of vision impairment, and that there is a high unmet need for spectacles, an appraisal of public sector arrangements for the correction of refractive error was conducted in eight Pacific Island countries. Mixed methods (questionnaire and semi-structured interviews) were used to collect information from eye care personnel (from Fiji, Papua New Guinea, Solomon Islands, Vanuatu, Cook Islands, Samoa, Tonga and Tuvalu) attending a regional eye health workshop in 2005. Fiji, Tonga and Vanuatu had Vision 2020 eye care plans that included refraction services, but not spectacle provision. There was wide variation in public sector spectacle dispensing services, but, except in Samoa, ready-made spectacles and a full cost recovery pricing strategy were the mainstay. There were no systems for the registration of personnel, nor guidelines for clinical or systems management. The refraction staff to population ratio varied considerably. Solomon Islands, Tuvalu and Vanuatu had the best coverage by services, either fixed or outreach. Most services had little promotional activity or community engagement. To be successful, it would seem that public sector refraction services should answer a real and perceived need, fit within prevailing policy and legislation, value, train, retain and equip employees, be well managed, be accessible and affordable, be responsive to consumers, and provide ongoing good quality outcomes. To this end, a checklist to aid the initiation and maintenance of refraction and spectacle systems in low-resource countries has been constructed.

    To evaluate the economic impact of automated-drug dispensing systems (ADS) in surgical intensive care units (ICUs). A financial analysis was conducted in three adult ICUs of one university hospital, where ADS were implemented, one in each unit, to replace the traditional floor stock system. Costs were estimated before and after implementation of the ADS on the basis of floor stock inventories, expired drugs, and time spent by nurses and pharmacy technicians on medication-related work activities. A financial analysis was conducted that included operating cash flows, investment cash flows, global cash flow and net present value. After ADS implementation, nurses spent less time on medication-related activities with an average of 14.7 hours saved per day/33 beds. Pharmacy technicians spent more time on floor-stock activities with an average of 3.5 additional hours per day across the three ICUs. The cost of drug storage was reduced by €44,298 and the cost of expired drugs was reduced by €14,772 per year across the three ICUs. Five years after the initial investment, the global cash flow was €148,229 and the net present value of the project was positive by €510,404. The financial modeling of the ADS implementation in three ICUs showed a high return on investment for the hospital. Medication-related costs and nursing time dedicated to medications are reduced with ADS.

    Lung cancer is the leading cause of cancer death worldwide. Although disruption of normal proliferation and differentiation is a vital component of tumorigenesis, the mechanisms of this process in lung cancer are still unclear. A transcription factor, C/EBPβ is a critical regulator of proliferation and/or differentiation in multiple tissues. In lung, C/EBPβ is expressed in alveolar pneumocytes and bronchial epithelial cells; however, its roles on normal lung homeostasis and lung cancer development have not been well described. Here we investigated whether C/EBPβ is required for normal lung development and whether its aberrant expression and/or activity contribute to lung tumorigenesis. We showed that C/EBPβ was expressed in both human normal pneumocytes and lung adenocarcinoma cell lines. We found that overall lung architecture was maintained in Cebpb knockout mice. Neither overexpression of nuclear C/EBPβ nor suppression of CEBPB expression had significant effects on cell proliferation. C/EBPβ expression and activity remained unchanged upon EGF stimulation. Furthermore, deletion of Cebpb had no impact on lung tumor burden in a lung specific, conditional mutant EGFR lung cancer mouse model. Analyses of data from The Cancer Genome Atlas (TCGA) revealed that expression, promoter methylation, or copy number of CEBPB was not significantly altered in human lung adenocarcinoma. Taken together, our data suggest that C/EBPβ is dispensable for development of lung adenocarcinoma.

    Full Text Available Aryl Hydrocarbon Receptor Nuclear Translocator/ hypoxia-inducible factor 1 beta (ARNT/ HIF1β, a member of bHLH-PAS family of transcriptional factors, plays a critical role in metabolic homeostasis, insulin resistance and glucose intolerance. The contributions of ARNT in pancreas, liver and adipose tissue to energy balance through gene regulation have been described. Surprisingly, the impact of ARNT signaling in the skeletal muscles, one of the major organs involved in glucose disposal, has not been investigated, especially in type II diabetes. Here we report that ARNT is expressed in the skeletal muscles, particularly in the energy-efficient oxidative slow-twitch myofibers, which are characterized by increased oxidative capacity, mitochondrial content, vascular supply and insulin sensitivity. However, muscle-specific deletion of ARNT did not change myofiber type distribution, oxidative capacity, mitochondrial content, capillarity, or the expression of genes associated with these features. Consequently, the lack of ARNT in the skeletal muscle did not affect weight gain, lean/fat mass, insulin sensitivity and glucose tolerance in lean mice, nor did it impact insulin resistance and glucose intolerance in high fat diet-induced obesity. Therefore, skeletal muscle ARNT is dispensable for controlling muscle fiber type and metabolic regulation, as well as diet-induced weight control, insulin sensitivity and glucose tolerance.

    A new mating disruption formulation for population control of a wide range of tortricid pests, including Spilonota ocellana, was tested in Swedish apple orchards during 2012-2013. Owing to the characteristics of the local agricultural landscape, mating disruption was evaluated in isolated orchards rather than through an area-wide approach. Parameters such as trap shutdown, communication disruption in field cages, damage level and dispenser emission were measured as efficacy indicators. The test formulation reduced the catches in monitoring traps for the entire range of the tested species. In field cages, communication between sexes was disrupted for both Adoxophyes orana and Cydia pomonella. The fruit damage caused by leafrollers (including S. ocellana) was reduced by the treatment. The device showed a constant release of all components for the entire flight activity period of these pests. Single-orchard experiments showed a significant effect on field populations of the leafroller species complex. While promising, in light of the variability of the result, field scouting may be required to enable practitioners to estimate the density of the pests and avoid possible unexpected attacks. Additional experiments are needed to evaluate the efficacy of the product against C. pomonella. © 2014 Society of Chemical Industry.

    In situ time-resolved X-ray absorption spectroscopy (XAS) measurements collected at the Pt L3-edge during the synthesis of Pt nanoparticles (NPs) in aqueous solution are reported. A specially designed dispenser-reactor apparatus allowed for monitoring changes in the XAS spectra from the earliest moments of Pt ions in solution until the formation of metallic nanoparticles with a mean diameter of 4.9 ± 1.1 nm. By monitoring the changes in the local chemical environment of the Pt atoms in real time, it was possible to observe that the NPs formation kinetics involved two stages: a reduction-nucleation burst followed by a slow growth and stabilization of NPs. Subsequently, the synthesized Pt NPs were supported on activated carbon and characterized by synchrotron-radiation-excited X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and extended X-ray absorption fine structure (EXAFS). The supported Pt NPs remained in the metallic chemical state and with a reduced size, presenting slight lattice parameter contraction in comparison with the bulk Pt values.

    Full Text Available The performance of Nile tilapia (Oreochromis niloticus raised in cages furnished with an automatic dispenser, supplied at different frequencies (once per hour and once every two hours and periods (daytime, nighttime and both was evaluated. Eighteen 1.0m³ cages were placed into a 2000m² pond, two meters deep with a 5% water exchange. One hundred and seventy tilapias, with initial weight of 16.0±4.9g, were dispersed into each 1m³ cage and the feed ration was adjusted every 21 days with biometry. Data was collected from March to July (autumn and winter. Significant difference to final weight (P<0.05 among treatments was observed. The increase in feeding frequency improves the productive performance of Nile tilapias in cages and permitted better management of the food. The better feed conversion rate for high feeding frequency (24 times day-1 can result in saving up to 360kg of food for each ton of fish produced, increasing the economic sustenance for tilapia culture and suggesting less environmental pollution.

    In order to develop jetting technologies of glue in LED and microelectronics packaging, giant-magnetostrictive-material (GMM) is firstly applied to increase jetting response, and a new magnifying device including a lever and a flexible hinge is designed to improve jetting characteristics. Physical models of the jetting system are derived from the magnifying structure and working principle, which involves circuit model, electro-magneto-displacement model, dynamic model and fluid-solid coupling model. The system model is established by combining mathematical models with Matlab-Simulink. The effectiveness of the GMM-based dispenser is confirmed by simulation and experiments. The jetting frequency significantly increases to 250 Hz, and dynamic behaviors jetting needle are evaluated that the velocity and displacement of the jetting needle reaches to 320 mm•s-1 and 0.11 mm respectively. With the increasing of the filling pressure or the amplitude of the current, the dot size will become larger. The dot size and working frequency can be easily adjusted.

    Coronin 1, a member of the evolutionary conserved coronin protein family, is highly expressed in all leukocytes. In mice and human, genetic inactivation of coronin 1 results in immuno-deficiencies that are linked to a strong reduction of naïve T cell numbers in peripheral organs, while memory/effector T cells, B cells, monocytes and neutrophils are less or not at all affected. Whether or not coronin 1 is important for leukocyte functions such as migration and phagocytosis has been a matter of debate. The current work addresses coronin 1-dependent leukocyte function by analyzing the response of coronin 1-deficient mice in a model of concanavalin A (Con A)-induced liver injury. Histological evaluation and determination of serum liver enzyme levels showed that coronin 1-deficient mice develop signs of acute hepatitis similar to Con A-treated wild type mice despite a reduced activation of T cells in the absence of coronin 1. Furthermore, analysis by intravital microscopy following Con A stimulation revealed that Gr-1+ neutrophils and CD4+ T cell adhesion in the post-sinusoidal venules increased in wild type as well as in coronin 1-deficient mice. These results suggest that coronin 1, while important for naïve T cell survival, is dispensable for other leukocyte function under inflammatory conditions in vivo. Copyright © 2013 Elsevier B.V.

  4. IL-6 Production by Dendritic Cells Is Dispensable for CD8+ Memory T-Cell Generation

    2013-01-01

    Full Text Available Following activation, naïve CD8+ T cells will differentiate into effectors that differ in their ability to survive: some will persist as memory cells while the majority will die by apoptosis. Signals given by antigen-presenting cells (APCs at the time of priming modulate this differential outcome. We have recently shown that, in opposition to dendritic cell (DC, CD40-activated B-(CD40-B cell vaccination fails to efficiently produce CD8+ memory T cells. Understanding why CD40-B-cell vaccination does not lead to the generation of functional long-lived memory cells is essential to define the signals that should be provided to naïve T cells by APCs. Here we show that CD40-B cells produce very low amount of IL-6 when compared to DCs. However, supplementation with IL-6 during CD40-B-cell vaccination did not improve memory generation. Furthermore, IL-6-deficient DCs maintained the capacity to promote the formation of functional CD8+ effectors and memory cells. Our results suggest that in APC vaccination models, IL-6 provided by the APCs is dispensable for proper CD8+ T-cell memory generation.

    A test stand has been set up to measure the current fluctuation noise properties of B- and M-type dispenser cathodes in a typical TWT gun structure. Noise techniques were used to determine the work function distribution on the cathode surfaces. Significant differences between the B and M types and significant changes in the work function distribution during activation and life are found. In turn, knowledge of the expected work function can be used to accurately determine the cathode-operating temperatures in a TWT structure. Noise measurements also demonstrate more sensitivity to space charge effects than the Miram method. Full automation of the measurements and computations is now required to speed up data acquisition and reduction. The complete set of equations for the space charge limited diode were programmed so that given four of the five measurable variables (J, J sub O, T, D, and V) the fifth could be computed. Using this program, we estimated that an rms fluctuation in the diode spacing d in the frequency range of 145 Hz about 20 kHz of only about 10 to the -5 power A would account for the observed noise in a space charge limited diode with 1 mm spacing.

    Full Text Available MicroRNAs (miRNAs are important regulators of reprogramming of somatic cells into induced pluripotent stem cells (iPSCs; however, it is unclear whether miRNAs are required for reprogramming and whether miRNA activity as a whole facilitates reprogramming. Here we report on successful reprogramming of mouse fibroblasts and neural stem cells (NSCs lacking Dgcr8, a factor required for the biogenesis of canonical miRNAs, by Yamanaka factors, albeit at decreased efficiencies. Though iPSCs derived from Dgcr8-deficient mouse fibroblasts or NSCs were able to self-renew and expressed pluripotency-associated markers, they exhibited poor differentiation potential into mature somatic tissues, similar to Dgcr8−/− embryonic stem cells. The differentiation defects could be rescued with expression of DGCR8 cDNA. Our data demonstrate that while miRNA activity as a whole facilitates reprogramming, canonical miRNA may be dispensable in the derivation of iPSCs.

    Inkjet dispensing is a promising method for patterning cells and biomaterials for tissue engineering applications. In a novel approach, this work uses a biocompatible surfactant to improve the reliability of droplet formation in piezoelectric drop-on-demand inkjet printing of Hep G2 hepatocytes onto hydrogels. During a long printing process, cell aggregation and sedimentation within the inkjet reservoir can lead to inconsistent printing results. In order to improve repeatability, the effects of gentle agitation on cell sedimentation and aggregation within the inkjet reservoir were also investigated. Cell viability and proliferation when printed onto prepared collagen substrates were assessed using live/dead staining and the Alamar Blue metabolic assay. The addition of 0.05% Pluronic as a surfactant did not reduce cell viability, which remained above 95% 2 days after printing. The surfactant improved the reliability of droplet formation. Although gentle stirring of the inkjet reservoir was sufficient to maintain a cell suspension and reduce sedimentation, aggregation within the suspension continued to affect printing performance over a 180 min printing period.

    In the United Kingdom, pharmaceutical services can be delivered by both community pharmacies (CPs) and dispensing doctor practices (DPs). Both must adhere to minimum standards set out in NHS regulations; however, no common framework exists to guide quality improvement. Previous phases of this research had developed a set of characteristics indicative of good pharmaceutical service provision. To ask key stakeholders to confirm, and rank the importance of, a set of characteristics of good pharmaceutical service provision. A two-round Delphi-type survey was conducted in south-west England and was sent to participants representing three stakeholder groups: DPs, CPs and patients/lay members. Participants were asked to confirm, and rank, the importance of these characteristics as representing good quality pharmaceutical services. Thirty people were sent the first round survey; 22 participants completed both rounds. Median ratings for the 23 characteristics showed that all were seen to represent important aspects of pharmaceutical service provision. Participants' comments highlighted potential problems with the practicality of the characteristics. Characteristics relating to patient safety were deemed to be the most important and those relating to public health the least important. A set of 23 characteristics for providing good pharmaceutical services in CPs and DPs was developed and attained approval from a sample of stakeholders. With further testing and wider discussion, it is hoped that the characteristics will form the basis of a quality improvement tool for CPs and DPs. © 2016 Royal Pharmaceutical Society.

    The Energy Independence and Security Act of 2007 targets use of 36 billion gallons of biofuels per year by 2022. Achieving this may require substantial changes to current transportation fuel systems for distribution, dispensing, and use in vehicles. The U.S. Department of Energy and the National Renewable Energy Laboratory designed a system dynamics approach to help focus government action by determining what supply chain changes would have the greatest potential to accelerate biofuels deployment. The National Renewable Energy Laboratory developed the Biomass Scenario Model, a system dynamics model which represents the primary system effects and dependencies in the biomass-to-biofuels supply chain. The model provides a framework for developing scenarios and conducting biofuels policy analysis. This paper focuses on the downstream portion of the supply chain-represented in the distribution logistics, dispensing station, and fuel utilization, and vehicle modules of the Biomass Scenario Model. This model initially focused on ethanol, but has since been expanded to include other biofuels. Some portions of this system are represented dynamically with major interactions and feedbacks, especially those related to a dispensing station owner's decision whether to offer ethanol fuel and a consumer's choice whether to purchase that fuel. Other portions of the system are modeled with little or no dynamics; the vehicle choices of consumers are represented as discrete scenarios. This paper explores conditions needed to sustain an ethanol fuel market and identifies implications of these findings for program and policy goals. A large, economically sustainable ethanol fuel market (or other biofuel market) requires low end-user fuel price relative to gasoline and sufficient producer payment, which are difficult to achieve simultaneously. Other requirements (different for ethanol vs. other biofuel markets) include the need for infrastructure for distribution and dispensing and

    Third-party certification/verification of dietary supplements (DS), although not mainstream, is one way to help ensure high-quality products. In the medical setting, physicians may prescribe DS to correct a deficiency or improve a health care outcome, and they want products of a certain standard of quality, free of adulteration/contamination. We reviewed DS dispensed from all Department of Defense military treatment facilities over a 5-year period to determine which products had been third-party reviewed and certified/verified. By using product name, manufacturer, and/or National Drug Codes, we examined product listings on the websites of three independent-evaluating organizations. Over 1.5 million dietary supplement prescriptions consisting of 753 different products were dispensed from 2007 through 2011. Less than 3.6% of the products examined were third-party certified/verified by any of the three most well-known evaluation organizations: 19 were verified by United States Pharmacopeial Convention; 9 products were reviewed and 8 certified by ConsumerLab; and none of the products were certified by NSF International. Most DS dispensed by military treatment facilities are not reviewed by a third party. This is not unexpected, as third party certification is not yet mainstream. However, one way to reduce potential hazards and exposure to unsafe products is to encourage use of supplements that have third-party certification/verification.

    Behaviour modifying pheromones are well known agents for disrupting mating communication of pest insects. For optimal activity, they must be dispensed in time and space at a quantitatively measurable, predetermined release rate covering the flight period of the target species. Pheromones appeal to environmentally conscientious entomologists for their biodegradability, non-toxicity and ecological compatibility. In attempts of combining the virtues of pheromones, suitable slow release dispensers, and their mechanical deployment, an ecologically sensible, reasonably priced and patented procedure was developed and tested with the vineyard pest Lobesia botrana (Lep.: Tortricidae). It is characterized by (1) Electrospun mesofibers with diameters ranging from 0.6 to 3.5 micrometres, containing disruptants and dispensing it by slow release diffusion into the crop, (2) simultaneous application of the fully biodegradable combination of pheromone with Ecoflex polyester mesofiber, (3) combination of mechanical deployment by multi-purpose cultivators of the prefabricated pheromone dispensers with other simultaneous cultivation measures, and thus further reducing labour time and treatment costs. The dispensers are biodegradable within half a year without leaving any objectionable residues. In the standard eco-toxicology tests pheromone dispensers are harmless to non-target organisms. The disruptive effect of one treatment lasts for seven weeks which covers well one of several flight periods of L. botrana.

    During 2012–2013, solid Mallet TMR (trimedlure [TML], methyl eugenol [ME], raspberry ketone [RK]) wafers impregnated with DDVP (2, 2-dichlorovinyl dimethyl phosphate) insecticide were weathered during summer (8 wk) and winter (12 wk) in five California citrus-growing counties (Kern, Ventura, Orange, Tulare, and Riverside). In addition, TMR wafers without DDVP and with a Hercon Vaportape II insecticidal strip were compared with TMR dispensers with DDVP at Exeter and Riverside. Weathered treatments were shipped every week (overnight delivery) to Hawaii and frozen for a later bioassay in a 1,335-ha coffee plantation near Numila, Kauai Island, HI, where Mediterranean fruit fly, Ceratitis capitata (Wiedemann), oriental fruit fly, Bactrocera dorsalis Hendel, and melon fly, Bactrocera cucurbitae Coquillett, were all present. We compared trap captures of the three species, C. capitata, B. dorsalis, and B. cucurbitae, for the five different weathering locations. Captures of C. capitata, B. dorsalis, and B. cucurbitae with Mallet TMR dispensers (with DDVP) were not significantly different for the five locations. Captures with the Mallet TMR dispenser without DDVP and Vaportape were similar to those for Mallet TMR with DDVP, although there were some slight location differences. In conclusion, based on these results, the Mallet TMR dispenser could potentially be used in California habitats where large numbers of detection traps are currently deployed. Use of Vaportape with dispensers would not require them to be registered with US Environmental Protection Agency (EPA). Dispensers for use as Male Annihilation Technique (MAT) devi
