Drug-related problems and risk factors related to unplanned hospital readmission among cancer patients in Belgium.

INTRODUCTION: There are about 60,000 diagnoses of cancer per year in Belgium. After hospital care, about 12-13% of cancer patients are readmitted within 30 days after discharge. These readmissions are partly related to drug-related problems (DRP), such as interactions or adverse drug effects (ADE). OBJECTIVES: The aim of this study is to quantify and to classify DRP readmissions within 30 days for cancer patients and to highlight risk factors potentially correlated to readmissions. METHODS: This study is a 6-month observational retrospective study in two care facilities in Brussels: an academic general hospital and an academic oncology center. Patients readmitted within 30 days after their last hospital care for a potential DRP were included. Patient files were evaluated with an intermediate medication review that included interactions analysis (Lexicomp®). The probability of DRP readmission was assessed using the World Health Organization's Uppsala Monitoring Centre (WHO-UMC) system. RESULTS: The final population included 299 patients; among them, 123 (41.1%) were readmitted due to DRP (certain DRP (4.9%), probable DRP (49.6%), and possible DRP (45.5%)). Risks factors linked to these DRP were a low Charlson Comorbidity Index, polypharmacy, the kind of hospital, and some chemotherapies (platinum preparations). Among all readmitted patients, the D-type interactions were the most common (44.8%), which suggest a possible therapy modification. However, around 10% of interactions were X-type (drug combination to avoid). CONCLUSION: Almost 10% of patient readmitted within 30 days were potentially related to a DRP, most of them from adverse drug effects. Four risk factors (low Charlson Comorbidity Index, polypharmacy, the hospital, and some chemotherapies) were highlighted to prevent these readmissions.

Evaluation of compliance with isotretinoin PPP recommendations and exploration of reasons for non-compliance: Survey among French-speaking health care professionals and patients in Belgium.

PURPOSE: To evaluate awareness of and compliance in Belgium by French-speaking health care professionals and patients with the isotretinoin safety recommendations regarding its teratogenic risk. METHOD: Survey using online questionnaires, delivered from December 2014 to March 2015 for patients, pharmacists, dermatologists, and GPs and delivered again from September 2015 to October 2015 for GPs. RESULTS: Questionnaires were completed by 24 dermatologists, 24 GPs, 58 pharmacists, and 33 female patients. The pregnancy prevention programme was poorly known by health care professionals (23.6%) and patients (15.2%). Health care professionals informed women of childbearing age in depth about the teratogenic risk (98.3% of pharmacists and 100.0% of GPs and dermatologists) and the importance of an effective contraceptive method (87.9% and 100.0%, respectively). Patients were less informed about the pregnancy test (25.9% and 14.6%) and the need to use a second contraceptive method (29.3% and 27.1%). The low compliance with the last 2 recommendations was due to a lack of adoption by health care professionals regarding the need for these recommendations if female patients have an effective contraceptive method and the pregnancy risk is discussed in detail with them. CONCLUSION: The effectiveness of the pregnancy prevention programme recommendations should be reconsidered by an expert committee. Justifications should be added to effective recommendations to increase their adoption by health care professionals and patients.

Implementation study of an interprofessional medication adherence program for HIV patients in Switzerland: quantitative and qualitative implementation results.

BACKGROUND: An interprofessional medication adherence program (IMAP) for chronic patients was developed and successfully implemented in the community pharmacy of the Department of ambulatory care and community medicine (Lausanne, Switzerland). This study assesses the capacity of a physician and a nurse at the infectious diseases service of a public hospital and of community pharmacists in the Neuchâtel area (Switzerland) to implement the IMAP in their practice. METHODS: Mixed method, prospective, observational study. Quantitative and qualitative analyses of the implementation process were conducted following the RE-AIM model (reach, effectiveness, adoption, implementation and maintenance). RESULTS: Implementation started in November 2014. One physician, one nurse, and five pharmacists agreed to participate. Healthcare professionals perceived the benefits of the program and were motivated to implement it in their practice (adoption). Seventeen patients were included in the program; 13 refused to participate. The inclusion of naïve HIV patients was easier than the inclusion of experienced patients with difficult psychosocial issues (reach). Pharmacists were engaged in reinforcing patient medication adherence in 25% of interviews (effectiveness). Key facilitators expressed by healthcare professionals were patient inclusion by the physician and the nurse instead of the pharmacist and the organisation of regular meetings between all stakeholders. In contrast, the encountered barriers were the lack of time and resources, the lack of team uptake, and the lack of adoption by senior managers (implementation). Interviewed patients were all satisfied with this new program, encouraging healthcare professionals to scale it up. Structural changes allowed the hospital and one pharmacy to enter the maintenance stage (maintenance). CONCLUSION: The research team and collaboration between all professionals involved played an important role in this implementation. However, the dissemination of such a program to a larger scale and for the long term requires financial and structural resources as well as transitional external support.

Implementation of an interprofessional medication adherence program for HIV patients: description of the process using the framework for the implementation of services in pharmacy.

BACKGROUND: The community pharmacy center of the Department of Ambulatory Care and Community Medicine of the Policlinique Médicale Universitaire (PMU), Lausanne, Switzerland developed and implemented an interprofessional medication adherence program for chronic patients (IMAP). In 2014, a project was launched to implement the IMAP for HIV patients in a public non-academic hospital with the collaboration of community pharmacists in the Neuchâtel area (Switzerland). This article aims to describe the different implementation stages and strategies of the project. METHODS: A posteriori description of the implementation process, including the conceptualization strategies and stages (exploration, preparation, operation, sustainability) using the Framework for the Implementation of Services in Pharmacy (FISpH). RESULTS: In 2014, an attending infectious disease physician and a nurse at a public hospital (Neuchâtel, Switzerland) contacted the PMU to implement the IMAP in their setting in collaboration with community pharmacies. Five volunteer community pharmacies in Neuchâtel were trained to deliver the program. Three factors were found to be essential to the successful launch and progress of the implementation project: the experience of the community pharmacy center of the PMU with the IMAP, the involvement of the PMU research team, and collaboration with an external start up (SISPha) to train and support pharmacists. During the operation stage, the most important strategy developed was that of regular meetings between all stakeholders. These allowed healthcare professionals to discuss the implementation progress, to address each stakeholder's expectations, and to exchange experiences to facilitate interprofessional collaboration and program delivery. Structural changes allowed the formalization of the activities at the hospital and in a community pharmacy. This formalization was identified as the transition step between the operation and the sustainability stages. CONCLUSIONS: The transfer of the IMAP for HIV patients to a non-academic setting and its implementation are feasible. However, implementation of a new model of pharmacy service such as IMAP implies a deep change in practice. A transitional external support and the allocation of sufficient resources to carry out the IMAP are essential for its long-term sustainability.

Polymorphisms for ghrelin with consequences on satiety and metabolic alterations.

PURPOSE OF REVIEW: To understand the current trend of ghrelin genetic variations on the control of satiety, eating behaviours, obesity, and metabolic alterations, and its development over the last 18 months. RECENT FINDINGS: Several polymorphisms of the ghrelin gene, its receptor gene and ghrelin's acylating enzyme, ghrelin O-acyl transferase, have been identified and studied over the last decade in relation to control of satiety, obesity, eating behaviours, metabolic syndrome, glucose homeostasis, and type 2 diabetes. However, the effects described are either small or nonsignificant and often subjected to contradictory conclusions between studies. In the last 18 months, several of these areas of investigations have been revisited under more controlled conditions or have been subjected to meta-analysis. SUMMARY: The effects of ghrelin gene polymorphism, is a complex area of investigation, due to ghrelin's interplay with a host of various factors part of an integrative network. However, taken together, results suggest that there are no or nonsignificant effects of the common genetic variants. A better understanding of the network, probably by a systems biology type approach, will be necessary to assign the exact role played by gene polymorphism of the component of the ghrelin axis.

Patients and healthcare practitioners' perspective on the development of a digital interprofessional intervention for COPD.

Background: Chronic obstructive pulmonary disease (COPD) patients often have poor health literacy, leading to non-adherence to treatment and poor inhalation technique. Technological solutions can help manage COPD, but adherence tends to be low due to various factors. Objectives and Methods: We conducted a qualitative study to determine the needs of COPD patients and healthcare practitioners (HCPs) towards a mobile application and a web platform. We also aimed to identify potential barriers or facilitators to the use of such digital tools and their potential impact, and to assess the current state of collaboration between healthcare practitioners. Results: Our study found that COPD patients face difficulties in managing the disease and treatments, lack information and need easier contact with caregivers. Patients' needs include access to reliable information about COPD, its medical treatments and smoking cessation, help in maintaining good physical condition through adapted exercises, incentives and reminders, and crisis management protocols or a logbook. As patient needs can differ, it would be ideal if the mobile application could be customized. HCPs cite patient adherence, correct intake of the treatment, communication and lack of patient motivation as challenges. In particular, they would like to have access to information on patient follow-up and logbooks, as well as scientific documentation. They believe that interprofessional collaboration is essential for good patient care. However, lack of time is a major hurdle in optimizing this collaboration. Conclusion: Our study showed that most patients and HCPs view a technological platform positively to support the care of COPD patients and promote interprofessional collaboration.

New sustained-release intraarticular gel formulations based on monolein for local treatment of arthritic diseases.

Inflammatory osteoarthritis (OA) is characterized by painful and destructive inflammatory flares of a single joint, mainly in the back, the knees, the wrists or the hips. Monoarthritis is generally treated by intraarticular (IA) injections of corticosteroids or hyaluronic acid (HA). However, due to their toxicity, the chronic use of corticosteroids should be avoided. The aim of this work was to develop a new slow-release formulation for a parenteral route of administration (e.g., IA). The development's strategy was based on the use of amphiphilic ingredients such as glyceryl monooleate (GMO), which is able to generate viscous crystalline phase structures upon contact with an aqueous fluid (e.g., synovial fluid) to sustain the drug activity over weeks. Clonidine (CLO) was suggested as a small and hydrophilic model drug and HA as a hydrophilic viscoelastic scaffold. Thermal analyses showed that the stability of GMO, HA, and CLO in mixtures with a ratio of 1:1 (wt/wt) was not affected in comparison with the raw materials. In order to obtain a formulation presenting suitable syringeability and containing GMO, CLO, and HA, two elements were found to be essential: a minimum of about 15% (wt/wt) water content and the use of co-solvents such as ethanol (ET) and propylene glycol (PG), approved by the FDA for parenteral use. Several developed gels presented pseudoplastic flow behavior. Moreover, the best composition provided an in vitro release of CLO for about 1 week that was similar to a cubic reference formulation, described by many authors as presenting poor syringeability but the best sustained-release capacity.

Evaluation of the degradation of clonidine-loaded PLGA microspheres.

CONTEXT: The release of an encapsulated drug is dependent on diffusion and/or degradation/erosion processes. OBJECTIVE: This work aimed to better understand the degradation mechanism of clonidine-loaded microparticles. METHODS: Gel permeation chromatography was used to evaluate the degradation of the polymer. The water-uptake and the weight loss were determined gravimetrically. The swelling behaviour and the morphological changes of the formulations were observed by microscopy. The glass transition temperature and the crystallinity were also determined by differential scanning calorimetry and X-ray diffraction, respectively. The pH of the medium and inside the microspheres was assessed. RESULTS: The microspheres captured a large amount of water, allowing a decrease in the molecular weight of the polymer. The pH of the medium decreased after release of the degradation products and the pH inside the microparticles remained constant due to the neutralization of these acidic products. CONCLUSION: Clonidine and buffers both had an action on the degradation.

Asthma and COPD: Comparison with International Guidelines and Medication Adherence in Belgium.

Asthma and chronic obstructive pulmonary disease (COPD) are major chronic conditions. It is possible to limit their impact by controlling symptoms, which limits exacerbations and worsening of the disease, by choosing the appropriate treatment and ensuring that the patient adheres to it. The main purpose of this study was to assess medication adherence and persistence with inhaled medications for chronic treatment of asthma and COPD, as well as to evaluate the factors influencing this adherence. Medication adherence was measured from January 2013 to December 2016 using continuous multiple-interval measures of medication availability (CMA). Persistence was evaluated by treatment episodes (TE). We analyzed the influence of different factors on CMA such as sex, age, type of device, and the realization of the "new medicines service" (NMS), introduced in Belgium in October 2013 to support patients in adhering to their treatment. We also analyzed the consumption of these inhaled medications within the Belgian population and compared them with the Global Initiative for Asthma (GINA) and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommendations. Medication adherence varied greatly between the different pharmacological classes: inhaled corticosteroids (ICS) alone or in combination with long-acting beta agonists (LABA) had the lowest medication adherence and persistence, while adherence was highest for the long-acting muscarinic antagonists (LAMA) and LABA/LAMA associations. The NMS seemed to have a positive impact on medication adherence, although few patients completed the two guidance interviews offered by the service. In addition, only a minority of the targeted patients took advantage of this new service.

General practitioners-community pharmacists pharmacotherapy discussion groups: Analysis of their implementation through a series of case studies.

Background: The evolution of primary care practice has led to the implementation of pharmacotherapy discussion groups between general practitioners and community pharmacists (PPPDGs) in some countries. The aim of these groups is to improve drug prescribing practices and strengthen interprofessional relationships. Objective: To gain more insight into factors involved in successful implementation of PPPDGs. Methods: PPPDG implementation in three countries (Belgium, the Netherlands, Switzerland), was analyzed in a series of case studies. A grid describing different evaluation criteria was completed by stakeholders in their respective country. The data collection was followed by a literature review. Results: Various models were used to implement PPPDGs within each country and different dynamics were encountered. PPPDGs lead to positive effects on the quality and cost-effectiveness of drug prescribing and on the collaboration between general practitioners (GPs) and community pharmacists (CPs). Factors involved in implementation were also identified, such as expectations of GPs and CPs, configuration of the implemented model, and the role of CPs in the healthcare organization. Conclusions: This study provides insight into the factors involved in successful implementation of PPPDGs in Belgium, the Netherlands and Switzerland. The findings can be used by healthcare professionals to improve the safety, cost-effectiveness of drug prescriptions and systems in primary care. This study offers a starting point for further research in the field.

Design and Development of Tools for Risk Evaluation of Diabetes and Cardiovascular Disease in Community Pharmacy.

There is an increasing motivation to implement pharmacist-led screening services in community pharmacies. This study aims to develop tools to support the pharmacist in the context of a diabetes and cardiovascular disease risk assessment service. Our development involved a multistep process using a user-centred approach, including a need assessment phase (14 patients, 17 pharmacists) and a creative design phase, followed by the evaluation of the materials (10 patients, 16 pharmacists). Three following themes covering educational needs emerged from stakeholders' discussions: "content", "layout", and "form", with three additional themes regarding the practical organisation: "software", "awareness", and "referral". Based on the need assessment, tools for patient education purposes and awareness campaigns were created. During the development, special attention was paid to the writing style and structure with less text and more graphical colourful elements to suit patients with different health literacy and educational levels. The evaluation phase allowed researchers to observe participants engaging with the materials. Overall, participants were satisfied with the tools. The contents were considered valuable and relevant. However, adaptations were necessary to ensure their understanding and long-term usability. Finally, future research is required to evaluate the materials' impact on patients' behaviour towards their identified risk factors and ensure their effectiveness.

Cancer patients' behaviors and attitudes toward natural health products.

BACKGROUND: Natural health products (NHPs), including vitamins, minerals, and herbal supplements, are the most common complementary and alternative medicine (CAM) among cancer patients. Our survey determined the attitudes and behaviors of cancer patients toward natural complementary therapies that should be considered to implement an integrative approach in the future. METHODS: Our survey was conducted in four hospitals in Belgium. Questionnaires were posted online from October 2020 to October 2021 for cancer patients. Descriptive statistics were used to analyze the data. A [Formula: see text] test was applied to study the type of NHP consumed according to diagnosis time. Fischer's exact test compared patients who had changed their consumption since diagnosis and those who had not. RESULTS: Out of 349 questionnaires collected, only 59 met all inclusion criteria. 83.1 % of the patients agreed that conventional medicine (CM) could benefit from complementary therapies, but they did not estimate (72.3 % of the patients) that those latter are more effective than conventional medicine. More than half of the patients used five or more NHPs. The most frequent NHPs consumed daily were vitamins (64.4 %), followed by other products (i.e., probiotics, gemmotherapy, birch sap and omega 3/6) (42.4 %) and herbs (40.7 %). Almost all patients started taking NHPs before their cancer diagnosis, but 72.7 % have changed their consumption significantly (p = 0.009) since their diagnosis. Boosting the immune system (79.7 %) and limiting conventional treatment side effects (76.9 %) were the most common reasons for NHPs' use. 74.4 % of the patients did not take complementary therapies to delay or avoid conventional treatment. CONCLUSIONS: The combination and high diversity of NHPs consumption highlight the importance of educating patients and healthcare providers (HCPs) about the risk of drug interactions associated with these natural products. Most cancer patients are more interested in using this non-mainstream medicine to complement their conventional treatment than as an alternative. Knowing the patients' reasons and understanding patients' attitudes toward NHPs will be essential for HCPs to address NHPs' use.

Herb-anticancer drug interactions in real life based on VigiBase, the WHO global database.

Cancer patients could combine herbal treatments with their chemotherapy. We consulted VigiBase, a WHO database of individual case safety reports (ICSRs) which archives reports of suspected Adverse Drug Reactions (ADRs) when herbal products are used in conjunction with anti-cancer treatment. We focused on the possible interactions between antineoplastic (L01 ATC class) or hormone antagonists (L02B ATC class) with 10 commonly used herbs (pineapple, green tea, cannabis, black cohosh, turmeric, echinacea, St John's wort, milk thistle and ginger) to compare ADRs described in ICSRs with the literature. A total of 1057 ICSRs were extracted from the database but only 134 were complete enough (or did not concern too many therapeutic lines) to keep them for analysis. Finally, 51 rationalizable ICSRs could be explained, which led us to propose a pharmacokinetic or pharmacodynamic interaction mechanism. Reports concerned more frequently women and half of the rationalizable ICSRs involved Viscum album and Silybum marianum. 5% of the ADRs described could have been avoided if clinicians had had access to the published information. It is also important to note that in 8% of the cases, the ADRs observed were life threatening. Phytovigilance should thus be considered more by health care professionals to best treat cancer patients and for better integrative care.

Analysis of the Consumption of Drugs Prescribed for the Treatment of Asthma in Belgian Children.

(1) Asthma is one of the most common chronic diseases in the world among children. The main purpose of this study was to analyze the consumption of asthma medications in order to investigate asthma in children (2-18 years) and the association with health care consumption; (2) a retrospective study using anonymized administrative data for 2013-2018 from the third largest Belgian health insurer was conducted; (3) in 2018, 12.9% of children received at least one asthma medication and 4.4% received at least two packages with a minimum of 30 days between purchases. Preschool children (2-6 years) were three times more likely to take asthma medication than older children (7-18 years). ICS, in combination or not with LABA, were the most dispensed drugs among children. Children with asthma medications were almost twice as likely to receive antibiotics, more likely to end up in the emergency room, and twice as likely to be hospitalized; (4) most children took ICS, according to the GINA guidelines. High rates of nebulization in young children were observed, despite the recommendation to use an inhaler with a spacing chamber as much as possible. Finally, children who took asthma medications were more likely to end up in the ER or be hospitalized.

Design and Implementation of a Computerized Management System for Adverse Drug Reactions at the Sourô SANOU University Hospital (CHUSS) in Bobo-Dioulasso, Burkina Faso.

Pharmacovigilance is the science and activities related to the detection, evaluation, understanding and prevention of adverse drug reactions or any other possible drug-related problems. In our tropics, this discipline is in an embryonic state. The availability of a management system capable of responding to pharmacovigilance activities is the main objective of our study. The coding was done on the DJANGO Framework. Signal detection was done using the ROR method. We designed three modules which are the notification module, the analysis module and the statistics module. This study has allowed us to launch the basis for a computerization of the pharmacovigilance information system and partly meets our objective. However, it could lead to the integration of the dictionary of adverse effects such as MedDRA as well as the International Classification of Medicines (ATC, EphMRA).

Diabetes and Cardiovascular Diseases Risk Assessment in Community Pharmacies: An Implementation Study.

The implementation of a new service is often challenging when translating research findings into routine clinical practices. This paper presents the results of the implementation study of a pilot project for a diabetes and cardiovascular diseases risk-assessment service in Belgian community pharmacies. To evaluate the implementation of the service, a mixed method was used that follows the RE-AIM framework. During the testing stage, 37 pharmacies participated, including five that dropped out due to a lack of time or COVID-19-related temporary obligations. Overall, 502 patients participated, of which 376 (74.9%) were eligible for according-to-protocol analysis. Of these, 80 patients (21.3%) were identified as being at high risk for the targeted diseases, and 100 (26.6%) were referred to general practice for further investigation. We presented the limited effectiveness and the key elements influencing optimal implementation. Additional strategies, such as interprofessional workshops, a data-sharing platform, and communication campaigns, should be considered to spread awareness of the new role of pharmacists. Such strategies could also promote collaboration with general practitioners to ensure the follow-up of patients at high risk. Overall, this service was considered easy to perform and feasible in practice but would require financial and external support to ensure its effectiveness, sustainability, and larger-scale implementation.

Studying the impact of a medication use evaluation by the community pharmacist (Simenon): Drug-related problems and associated variables.

BACKGROUND: A medication use review (MUR) aims to optimize medication use, patient knowledge and can improve health outcomes. This pharmaceutical care service is not yet available in Belgium. OBJECTIVES: To describe drug-related problems (DRPs) detected during a MUR, subsequent interventions proposed by pharmacists and evolution of DRPs until follow-up and to identify patient-related variables associated with the number of reported DRPs. METHODS: Belgian community pharmacists provided a MUR to older polymedicated ambulatory patients and registered DRPs, interventions and resolution at follow-up using the PharmDISC classification. The relationship between 14 patient-related variables and the number of reported DRPs was investigated with univariate analysis. A prediction model was developed with significant variables using negative binomial regression analysis. RESULTS: Across 56 pharmacies, 453 patients received a MUR and 1196 DRPs were registered (median 3DRPs/patient, range 0-10). Only for 11.7% of patients no problems were identified. The top-3 causes were interaction (15.2%), inappropriate timing or frequency (13.5%) and adverse effect (11.9%). The top-3 recommended interventions by pharmacists were transmission of information (25.1%), in-depth patient counselling (15.0%) and therapy stop (8.2%). After six weeks, 42.6% of DRPs were resolved; data was missing for 33.3%. A higher number of chronic drugs, female gender and living alone were associated with more DRPs. The prediction model found that per additional chronic drug, the number of problems increases by 4.3% (95% CI: 2.0-6.6%). Male gender decreases DRPs by 22.1% (95% CI: 10.4-32.0%). Living alone provided no additional predictive value in the prediction model. Confounding process- and pharmacist-related variables also influenced the number of reported DRPs. CONCLUSION: A MUR appears an effective strategy to detect and resolve DRPs. The number of chronic medications and female gender predict a higher number of DRPs. These findings are a starting point for evidence-based eligibility criteria for a MUR service in Belgium.

Implementation study of an intermediate medication review in Belgian community pharmacies.

BACKGROUND: The Association of Pharmacists in Belgium (APB) and local pharmacy associations launched a pilot project in collaboration with research teams from three Belgian universities to study the impact and implementation-related issues of a medication review (MR) service type 2a in Belgian community pharmacies. OBJECTIVE: The aim of this paper is to describe the implementation process of the MR service and to present the implementation evaluation of the pilot study (testing stage). METHODS: The pilot project was a prospective observational study using mixed methods. The implementation evaluation was based on the RE-AIM model and the framework for the implementation of services in pharmacy (FISpH). Collected implementation outcomes were classified into four dimensions: reach, adoption, implementation and intent of maintenance. RESULTS: During the testing stage, 80 pharmacies participated in the study, but 25 dropped out (31%), mainly because of a reported lack of time (adoption). The 55 remaining pharmacies included 457 patients. Recruiting patients into the service was challenging for pharmacists as 48.5% of patients refused the pharmacists' proposal (reach). Internal organizational factors were major barriers for pharmacists, followed by the lack of adoption by the pharmacy team. Large pharmacies in which pharmacy owner led the project were observed to be more proactive in implementing the MR service by integrating organizational strategies to assist the implementation process (implementation). Interviewed pharmacists perceived this new service as a professionally satisfying activity. Among participating pharmacists, 92.5% found this service feasible in practice, but believed it required adapted resources to reorganize the internal pharmacy workload, additional support, such as broad-based media campaigns to increase physicians' and patients' awareness and attitudes towards the service, and modified software (maintenance). CONCLUSIONS: The medication review service was implemented in 68% of participating pilot Belgian community pharmacies but would require adapted resources and supports for larger scale implementation.

Ghrelin: a new peptide regulating growth hormone release and food intake.

Ghrelin, identified as an endogenous ligand for the growth hormone secretagogue receptor, is a 28 amino acid peptide hormone possessing an unusual octanoyl group on the serine in position 3, crucial for its biological activity. Ghrelin is predominantly produced by the stomach but also by many other tissues such as pituitary, hypothalamus, duodenum, jejunum, ileum, colon, lung, heart, pancreas, kidney, and testis. In addition to stimulation of GH release, ghrelin stimulates appetite and food intake, enhancing fat mass deposition and weight gain. Besides these main actions, ghrelin regulates gastric motility and acid secretion, exerts cardiovascular and anti-inflammatory effects, modulates cell proliferation and influences endocrine and exocrine pancreatic secretion, as well as glucose and lipid metabolism. Therefore, ghrelin agonists and antagonists might be valuable for some clinical aspects.

An open randomized controlled study comparing an online text-based scenario and a serious game by Belgian and Swiss pharmacy students.

INTRODUCTION: To compare online learning tools, looped, branch serious game (SG) and linear text-based scenario (TBS), among a sample of Belgian and Swiss pharmacy students. METHODS: Open randomized controlled study. The lesson was based on the case of a benign cough in a healthy child. A randomized sample of 117 students: only the Swiss students had attended a previous lecture on coughs. Participation rate, pre- and post-experience Likert scales and students' clinical knowledge were measured. RESULTS: Our primary hypothesis was demonstrated: students favored the SG even if navigation was rated as more complex, and students who performed the SG better understood the aim of pharmacist triage in case of cough. The influence of the SG appeared to be linked to the presence of a previous lecture in the curriculum. DISCUSSION AND CONCLUSION: SG and TBS are effective to teach pharmacist triage. Higher SG complexity should be used to teach the aim of pharmacist triage in the case of a specific disease and could be an alternative to simulated patients. A simpler TBS does not require a previous lecture and a debriefing to be fully effective.
