Rasharkin Health Initiative

This project will build on previous work carried out over the last 3 years. There are 4 main aspects: - intergenerational work focusing on the development of a vegetable garden with pharmacy input on health advice - develop and promote the lunch club which has been very successful to date and has targeted people previously not accessing support or community services in the village - annual health fair - local carer’s advice centre to provide practice information and signposting services. This last aspect is the result of ongoing identification of the need to support carers over the last 2 years of the BCPP project. This project will be driven forward by a lay health worker working closely with the pharmacist Outcome: The project built on previous work. Some of the work included: health fayre, intergenerational garden, and luncheon club. Results from questionnaires showed that the project increased people's awareness of the causes of ill-health and how they might deal with them. People now see the pharmacist as a local and not just as someone dispensing medicine.

Oportunidades de mejora del servicio de metadona en atención primaria, desde el punto de vista profesional

Objective: To identify and prioritize improvement opportunities, according to the European Foundation for Quality Management model (EFQM) model, of the methadone dispensing service in Andalusian Primary Health Care, from the point of view of professionals. Method: Delphi consensus method, implemented from September 2007 to March 2008 by means of three rounds of interviews with questionnaires administered by electronic mail to 39 professionals. The Panel of experts was made up of Dispensers and Prescribers of methadone as well as Coordinators of welfare services from the Methadone Treatment Program (MTP). Selection criteria were: Being in active employment with a minimum of 3 years experience. Sample diversification variables: Professional role, geographical environment and type of habitat. Recruitment: By means of key professional bodies from different institutions. Results: 48 improvement opportunities were identified. Thirteen of these obtained a high level of agreement in the final round. According to the EFQM model, the dimensions that obtained the most consensus in relation to improving the care service were: Leadership, Alliances and Resources. The dimension that caused the greatest disagreement was Processes. Conclusions: In spite of its having been implemented since 1997 in Andalusian Primary Health Care, the methadone dispensing service is at an implementation phase, rather than what could be classed as a fully deployed stage

The utility of anti-trypomastigote lytic antibodies for determining cure of Trypanosoma cruzi infections in treated patients: an overview and perspectives

In previous work, we proposed alternative protocols for following patients with treated Chagas disease and these are reviewed herein. Evidence was provided to support the following: (i) functional anti-trypomastigote antibodies are indicative of ongoing chronic Trypanosoma cruzi infections; (ii) specific antibodies detected by conventional serology (CS) with epimastigote extracts, fixed trypomastigotes or other parasite antigens may circulate years after parasite elimination; (iii) functional antibodies are evidenced by complement-mediated lysis of freshly isolated trypomastigotes, a test which is 100% specific, highly sensitive, and the first to revert after T. cruzi elimination and (iv) the parasite target for the lytic antibodies is a glycoprotein of high molecular weight (gp160) anchored at the parasite surface. The complement regulatory protein has been cloned, sequenced and produced as a recombinant protein by other groups and is useful for identifying functional anti-T. cruzi antibodies in ELISA tests, thus dispensing with the need for live trypomastigotes to manage treated patients. If used instead of CS to define cures for Chagas patients, ELISA will avoid unnecessary delays in finding anti-T. cruzi drugs. Other highly sensitive techniques for parasite DNA detection, such as PCR, need to be standardized and included in future protocols for the management of patients with drug-treated Chagas disease.

Estudio piloto sobre el manejo de la fluidoterapia intravenosa en pacientes adultos de un hospital de tercer nivel.

The purpose of intravenous fluid therapy (IFT) is to maintain or restore internal equilibrium by administering fluids and/or different electrolyte components. Its correct use and the prevention of complications arising from their misuse depend on the knowledge of the medical team on this subject. We analyzed this issue in different clinical areas of a tertiary hospital. MATERIAL AND METHODS We performed a descriptive cross-sectional pilot study via a questionnaire given to physicians specializing in internal medicine (IM) and digestive system surgery (SDS) who perform clinical practice in hospital units with unit dose drug dispensing system. We designed an anonymous questionnaire with 25 questions relative to knowledge of theory and practices, as well as the opinion of physicians regarding IFT. We evaluated the association between nominal qualitative variables with the Chi-square or Fisher's exact test. The behavior of the quantitative variables was assessed using the t-student test. The analysis of the data was generated using SAS/STAT, Version 9. RESULTS 28 questionnaires were collected from 13 surgeons and 15 digestive interns. Over 40% of specialists considered further education in IFT a necessity , especially regarding its prescription (SDS: 61.54%, IM: 71.43%). No statistically significant differences were found between the specialties in terms of perceived frequency of complications associated with IFT or in the frequency indication with the exception of hypovolemic shock, which is considered to be more prevalent in gastrointestinal surgery (p = 0.046). 90% of professionals prefer an individualized prescription. Statistically significant differences in terms of scores in the area of knowledge, with IM physicians achieving the highest scores (p = 0.014). There were also differences in attitude but they are not significant (p = 0.162). Knowledge of intravenous fluid increases with years of clinical experience (Spearman correlation coefficient = 0.386, p = 0.047). CONCLUSIONS The professionals who prescribe IFT perceive the need to design IFT training programs, together with the production of guides and consensus protocols.

Outpatient prescriptions practice and writing quality in a paediatric university hospital.

BACKGROUND: The writing of prescriptions is an important aspect of medical practice. This activity presents some specific problems given a danger of misinterpretation and dispensing errors in community pharmacies. The objective of this study was to determine the evolution of the prescription practice and writing quality in the outpatient clinics of our paediatric university hospital.¦METHODS: Copies of prescriptions written by physicians were collected from community pharmacies in the region of our hospital for a two-month period in 2005 and 2010. They were analysed according to standard criteria, including both formal and pharmaceutical aspects.¦RESULTS: A total of 597 handwritten prescriptions were reviewed in 2005 and 633 in 2010. They contained 1,456 drug prescriptions in 2005 and 1,348 in 2010. Fifteen drugs accounted for 80% of all prescriptions and the most common drugs were paracetamol and ibuprofen. A higher proportion of drugs were prescribed as International Nonproprietary Names (INN) or generics in 2010 (24.7%) compared with 2005 (20.9%). Of the drug prescriptions examined, 55.5% were incomplete in 2005 and 69.2% in 2010. Moreover in 2005, 3.2% were legible only with difficulty, 22.9% were ambiguous, and 3.0% contained an error. These proportions rose respectively to 5.2%, 27.8%, and 6.8% in 2010.¦CONCLUSION: This study showed that fifteen different drugs represented the majority of prescriptions, and a quarter of them were prescribed as INN or generics in 2010; and that handwritten prescriptions contained numerous omissions and preventable errors. In our hospital computerised prescribing coupled with advanced decision support is eagerly awaited.

Ranibizumab versus Bevacizumab for Neovascular Age-related Macular Degeneration: Results from the GEFAL Noninferiority Randomized Trial.

OBJECTIVE: To evaluate the relative efficacy and safety profile of bevacizumab versus ranibizumab intravitreal injections for the treatment of neovascular age-related macular degeneration (AMD). DESIGN: Multicenter, prospective, noninferiority, double-masked, randomized clinical trial performed in 38 French ophthalmology centers. The noninferiority limit was 5 letters. PARTICIPANTS: Patients aged ≥50 years were eligible if they presented with subfoveal neovascular AMD, with best-corrected visual acuity (BVCA) in the study eye of between 20/32 and 20/320 measured on the Early Treatment of Diabetic Retinopathy Study chart and a lesion area of less than 12 optic disc areas (DA). METHODS: Patients were randomly assigned to intravitreal administration of bevacizumab (1.25 mg) or ranibizumab (0.50 mg). Hospital pharmacies were responsible for preparing, blinding, and dispensing treatments. Patients were followed for 1 year, with a loading dose of 3 monthly intravitreal injections, followed by an as-needed regimen (1 injection in case of active disease) for the remaining 9 months with monthly follow-up. MAIN OUTCOME MEASURES: Mean change in visual acuity at 1 year. RESULTS: Between June 2009 and November 2011, 501 patients were randomized. In the per protocol analysis, bevacizumab was noninferior to ranibizumab (bevacizumab minus ranibizumab +1.89 letters; 95% confidence interval [CI], -1.16 to +4.93, P < 0.0001). The intention-to-treat analysis was concordant. The mean number of injections was 6.8 in the bevacizumab group and 6.5 in the ranibizumab group (P = 0.39). Both drugs reduced the central subfield macular thickness, with a mean decrease of 95 μm for bevacizumab and 107 μm for ranibizumab (P = 0.27). There were no significant differences in the presence of subretinal or intraretinal fluid at final evaluation, dye leakage on angiogram, or change in choroidal neovascular area. The proportion of patients with serious adverse events was 12.6% in the bevacizumab group and 12.1% in the ranibizumab group (P = 0.88). The proportion of patients with serious systemic or ocular adverse events was similar in both groups. CONCLUSIONS: Bevacizumab was noninferior to ranibizumab for visual acuity at 1 year with similar safety profiles. Ranibizumab tended to have a better anatomic outcome. The results are similar to those of previous head-to-head studies. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

Development, design and validation of solid reference samples.

We developed a method of sample preparation using epoxy compound, which was validated in two steps. First, we studied the homogeneity within samples by scanning tubes filled with radioactive epoxy. We found within-sample homogeneity better than 2%. Then, we studied the homogeneity between samples during a 4.5 h dispensing time. The homogeneity between samples was found to be better than 2%. This study demonstrates that we have a validated method, which assures the traceability of epoxy samples.

Outpatient prescription writing quality in a paediatric general hospital

Introduction The writing of prescriptions is an important aspect of medical practice. Since 2006, the Swiss authorities have decided to impose incentives to prescribe generic drugs. The objectives of this study were 1) to determine the evolution of the outpatient prescription practice in our paediatric university hospital during 2 periods separated by 5 years; 2) to assess the writing quality of outpatient prescriptions during the same period.Materials & Methods Design: Copies of prescriptions written by physicians were collected twice from community pharmacies in the region of our hospital for a 2-month period in 2005 and 2010. They were analysed according to standard criteria regarding both formal and pharmaceutical aspects. Drug prescriptions were classified as a) complete when all criteria for safety were fulfilled, b) ambiguous when there was a danger of a dispensing error because of one or more missing criteria, or c) containing an error.Setting: Paediatric university hospital.Main outcome measures: Proportion of generic drugs; outpatient prescription writing quality.Results: A total of 651 handwritten prescriptions were reviewed in 2005 and 693 in 2010. They contained 1570 drug prescriptions in 2005 (2.4 ± 1.2 drugs per patient) and 1462 in 2010 (2.1 ± 1.1). The most common drugs were paracetamol, ibuprofen, and sodium chloride. A higher proportion of drugs were prescribed as generic names or generics in 2010. Formal data regarding the physicians and the patients were almost complete, except for the patients' weight. Of the drug prescriptions, 48.5% were incomplete, 11.3% were ambiguous, and 3.0% contained an error in 2005. These proportions rose to 64.2%, 15.5% and 7.4% in 2010, respectively.Discussions, Conclusion This study showed that physicians' prescriptions comprised numerous omissions and errors with minimal potential for harm. Computerized prescription coupled with advanced decision support is eagerly awaited.Disclosure of Interest None Declared

Economics of Using Calcium Chloride vs. Sodium Chloride for Deicing/Anti-Icing, TR-488, 2008

The use of chemicals is a critical part of a pro-active winter maintenance program. However, ensuring that the correct chemicals are used is a challenge. On the one hand, budgets are limited, and thus price of chemicals is a major concern. On the other, performance of chemicals, especially at lower pavement temperatures, is not always assured. Two chemicals that are used extensively by the Iowa Department of Transportation (Iowa DOT) are sodium chloride (or salt) and calcium chloride. While calcium chloride can be effective at much lower temperatures than salt, it is also considerably more expensive. Costs for a gallon of salt brine are typically in the range of $0.05 to $0.10, whereas calcium chloride brine may cost in the range of $1.00 or more per gallon. These costs are of course subject to market forces and will thus change from year to year. The idea of mixing different winter maintenance chemicals is by no means new, and in general discussions it appears that many winter maintenance personnel have from time to time mixed up a jar of chemicals and done some work around the yard to see whether or not their new mix “works.” There are many stories about the mixture turning to “mayonnaise” (or, more colorfully, to “snot”) suggesting that mixing chemicals may give rise to some problems most likely due to precipitation. Further, the question of what constitutes a mixture “working” in this context is a topic of considerable discussion. In this study, mixtures of salt brine and calcium chloride brine were examined to determine their ice melting capability and their freezing point. Using the results from these tests, a linear interpolation model of the ice melting capability of mixtures of the two brines has been developed. Using a criterion based upon the ability of the mixture to melt a certain thickness of ice or snow (expressed as a thickness of melt-water equivalent), the model was extended to develop a material cost per lane mile for the full range of possible mixtures as a function of temperature. This allowed for a comparison of the performance of the various mixtures. From the point of view of melting capacity, mixing calcium chloride brine with salt brine appears to be effective only at very low temperatures (around 0° F and below). However, the approach described herein only considers the material costs, and does not consider application costs or other aspects of the mixture performance than melting capacity. While a unit quantity of calcium chloride is considerably more expensive than a unit quantity of sodium chloride, it also melts considerably more ice. In other words, to achieve the same result, much less calcium chloride brine is required than sodium chloride brine. This is important in considering application costs, because it means that a single application vehicle (for example, a brine dispensing trailer towed behind a snowplow) can cover many more lane miles with calcium chloride brine than with salt brine before needing to refill. Calculating exactly how much could be saved in application costs requires an optimization of routes used in the application of liquids in anti-icing, which is beyond the scope of the current study. However, this may be an area that agencies wish to pursue for future investigation. In discussion with winter maintenance personnel who use mixtures of sodium chloride and calcium chloride, it is evident that one reason for this is because the mixture is much more persistent (i.e. it stays longer on the road surface) than straight salt brine. Operationally this persistence is very valuable, but at present there are not any established methods to measure the persistence of a chemical on a pavement. In conclusion, the study presents a method that allows an agency to determine the material costs of using various mixtures of salt brine and calcium chloride brine. The method is based upon the requirement of melting a certain quantity of snow or ice at the ice-pavement interface, and on how much of a chemical or of a mixture of chemicals is required to do that.

Intravenous immunoglobulin for treatment of mild-to-moderate Alzheimer's disease: a phase 2, randomised, double-blind, placebo-controlled, dose-finding trial.

BACKGROUND: Three small trials suggest that intravenous immunoglobulin can affect biomarkers and symptoms of mild-to-moderate Alzheimer's disease. We tested the safety, effective dose, and infusion interval of intravenous immunoglobulin in such patients. METHODS: We did a multicentre, placebo-controlled phase 2 trial at seven sites in the USA and five in Germany. Participants with probable Alzheimer's disease aged 50-85 years were randomly assigned (by a computer-generated randomisation sequence, with block sizes of eight) to infusions every 4 weeks (0·2, 0·5, or 0·8 g intravenous immunoglobulin per kg bodyweight, or placebo) or infusions every 2 weeks (0·1, 0·25, or 0·4 g/kg, or placebo). Patients, caregivers, investigators assessing outcomes, and staff at imaging facilities and the clinical research organisation were masked to treatment allocation, but dispensing pharmacists, the statistician, and the person responsible for final PET analyses were not. Treatment was masked with opaque pouches and infusion lines. The primary endpoint was median area under the curve (AUC) of plasma amyloid β (Aβ)(1-40) between the last infusion and the final visit (2 weeks or 4 weeks depending on infusion interval) in the intention-to-treat population. The trial is registered at ClinicalTrials.gov (NCT00812565) and controlled-trials.com (ISRCTN64846759). FINDINGS: 89 patients were assessed for eligibility, of whom 58 were enrolled and 55 included in the primary analysis. Median AUC of plasma Aβ(1-40) was not significantly different for intravenous immunoglobulin compared with placebo for five of the six intervention groups (-18·0 [range -1347·0 to 1068·5] for 0·2 g/kg, -364·3 [-5834·5 to 1953·5] for 0·5 g/kg, and -351·8 [-1084·0 to 936·5] for 0·8 g/kg every 4 weeks vs -116·3 [-1379·0 to 5266·0] for placebo; and -13·8 [-1729·0 to 307·0] for 0·1 g/kg, and -32·5 [-1102·5 to 451·5] for 0·25 g/kg every 2 weeks vs 159·5 [51·5 to 303·0] for placebo; p>0·05 for all). The difference in median AUC of plasma Aβ(1-40) between the 0·4 g/kg every 2 weeks group (47·0 [range -341·0 to 72·5]) and the placebo group was significant (p=0·0216). 25 of 42 (60%) patients in the intervention group versus nine of 14 (64%) receiving placebo had an adverse event. Four of 42 (10%) patients in the intravenous immunoglobulin group versus four of 14 (29%) receiving placebo had a serious adverse event, including one stroke in the intervention group. INTERPRETATION: Intravenous immunoglobulin may have an acceptable safety profile. Our results did not accord with those from previous studies. Longer trials with greater power are needed to assess the cognitive and functional effects of intravenous immunoglobulin in patients with Alzheimer's disease.

The incidence and selection of multiple mating in plants.

Mating with more than one pollen donor, or polyandry, is common in land plants. In flowering plants, polyandry occurs when the pollen from different potential sires is distributed among the fruits of a single individual, or when pollen from more than one donor is deposited on the same stigma. Because polyandry typically leads to multiple paternity among or within fruits, it can be indirectly inferred on the basis of paternity analysis using molecular markers. A review of the literature indicates that polyandry is probably ubiquitous in plants except those that habitually self-fertilize, or that disperse their pollen in pollen packages, such as polyads or pollinia. Multiple mating may increase plants' female component by alleviating pollen limitation or by promoting competition among pollen grains from different potential sires. Accordingly, a number of traits have evolved that should promote polyandry at the flower level from the female's point of view, e.g. the prolongation of stigma receptivity or increases in stigma size. However, many floral traits, such as attractiveness, the physical manipulation of pollinators and pollen-dispensing mechanisms that lead to polyandrous pollination, have probably evolved in response to selection to promote male siring success in general, so that polyandry might often best be seen as a by-product of selection to enhance outcross siring success. In this sense, polyandry in plants is similar to geitonogamy (selfing caused by pollen transfer among flowers of the same plant), because both polyandry and geitonogamy probably result from selection to promote outcross siring success, although geitonogamy is almost always deleterious while polyandry in plants will seldom be so.

Apteekkien kannattavuuden kehittäminen toimintolaskentaa soveltaen

Apteekkiliiketoiminta eroaa tavallisesta liiketoiminnasta erilaisten lakisääteisten velvoitteiden vuoksi. Alan regulaation viimeaikainen kehitys, kuten lääkevaihto, viitehintajärjestelmä sekä näiden tuoma lääkkeiden tiukentunut hintakilpailu, ovat tuoneet haasteita apteekkien kannattavuuteen. Tuotevalikoima- ja varastonhallinta ovat nousseet yhä tärkeämpään rooliin. Tutkimuksen tavoitteena oli kehittää apteekkien kannattavuutta toimintolaskentaa soveltaen. Toimintolaskennalla kahdelle apteekille tuotettiin kustannus- sekä tuotekannattavuustietoa. Tutkimuksen teoreettinen viitekehys koostui toimintolaskennan sekä apteekkiliiketoiminnan aikaisemmasta tutkimuksesta. Tutkimuksesta kävi ilmi, että kummassakin apteekissa oli erittäin laaja tuotesortimentti. Itsehoito- sekä vapaan kaupan tuotteiden tuotesortimenttia järkeistämällä kannattavuutta voitaisiin parantaa. Monesti tuotekategorioissa on useita saamaa vaikuttavaa ainetta sisältävää valmistetta usealta eri toimittajalta mikä heikentää kannattavuutta. Tuloksista kävi ilmi myös, että tulevaisuudessa vapaan kaupan tuotteet tulevat olemaan tärkeässä roolissa, mikä korostaa markkinointi- ja myyntiosaamisen tärkeyttä. Reseptilääkkeissä kate ei näyttäisi kattavan kustannuksia, minkä vuoksi varastonhallintaan on kiinnitettävä huomiota.
