- BackgroundThe first-line medication gabapentin and the acetylcholinesterase inhibitor donepezil represent a new promising combination to improve treatment outcomes for patients with severe neuropathic pain. The drugs have previously shown synergism following co-administration in nerve-injured rats. MethodsThe clinical relevance of adding donepezil to existing gabapentin treatment in patients with post-traumatic neuropathic pain was explored in this open-label study. The study comprised two consecutive periods of minimum 6 weeks: (1) titration of gabapentin to the highest tolerable dose or maximum 2400mg daily, and (2) addition of donepezil 5mg once daily to the fixed gabapentin dose. Efficacy and tolerability were assessed by ratings of pain intensity, questionnaires for pain and health-related quality of life, and reporting of adverse events. Pain scores were also analysed using mixed-effects analysis with the software NONMEM to account for intersubject variability. ResultsEight patients commenced treatment with donepezil, of which two withdrew because of adverse events. Addition of donepezil resulted in clinically relevant reductions of pain (>11 units on a 0-100 scale) and improved mental wellness in three of six patients. The remaining three patients had no obvious supplemental effect. Mixed-effects analysis revealed that pain scores were significantly lower during co-administration (P<0.0001 combination vs. monotherapy). ConclusionDonepezil may provide additional analgesia to neuropathic pain patients with insufficient pain relief from gabapentin as monotherapy. The promising results support controlled clinical trials of the drug combination. The usefulness of mixed-effects analysis in small-scale trials and/or for data with high intersubject variability was also demonstrated.

- Dasatinib (DAS) and interferon-a have antileukemic and immunostimulatory effects and induce deep responses in chronic myeloid leukemia (CML). We assigned 40 newly diagnosed chronic-phase CML patients to receive DAS 100 mg o.d. followed by addition of pegylated interferon-alpha 2b (PegIFN) after 3 months (M3). The starting dose of PegIFN was 15 mu g/week and it increased to 25 mu g/week at M6 until M15. The combination was well tolerated with manageable toxicity. Of the patients, 84% remained on PegIFN at M12 and 91% (DAS) and 73% (PegIFN) of assigned dose was given. Only one patient had a pleural effusion during first year, and three more during the second year. After introduction of PegIFN we observed a steep increase in response rates. Major molecular response was achieved in 10%, 57%, 84% and 89% of patients at M3, M6, M12 and M18, respectively. At M12, MR4 was achieved by 46% and MR4.5 by 27% of patients. No patients progressed to advanced phase. In conclusion, the combination treatment appeared safe with very promising efficacy. A randomized comparison of DAS +/- PegIFN is warranted.

- Application of AI technologies in synthesis prediction has developed very rapidly in recent years. We attempt here to give a comprehensive summary on the latest advancement on retro-synthesis planning, forward synthesis prediction as well as quantum chemistry-based reaction prediction models. Besides an introduction on the AI/ML models for addressing various synthesis related problems, the sources of the reaction datasets used in model building is also covered. In addition to the predictive models, the robotics based high throughput experimentation technology will be another crucial factor for conducting synthesis in an automated fashion. Some state-of-the-art of high throughput experimentation practices carried out in the pharmaceutical industry are highlighted in this chapter to give the reader a sense of how future chemistry will be conducted to make compounds faster and cheaper. © 2020 Elsevier Ltd

- Background Antibiotic overuse and misuse in primary care are common, highlighting the importance of antimicrobial stewardship (AMS) efforts in this setting. Audit and feedback (A&F) interventions can improve professional practice and performance in some settings. Objectives and methods To leverage the expertise from international members of the Joint Programming Initiative on Antimicrobial Resistance - Primary care Antibiotic Audit and feedback Network (JPIAMR-PAAN). Network members all have experience of designing and delivering A&F interventions to reduce inappropriate antibiotic prescribing in primary care settings. We aim to introduce the network and explore ongoing A&F activities in member regions. An online survey was administered to all network members to collect regional information. Results Fifteen respondents from 11 countries provided information on A&F activities in their country, and national/regional antibiotic stewardship programmes or policies. Most countries use electronic medical records as the primary data source, antibiotic appropriateness as the main outcome of feedback, and target GPs as the prescribers of interest. Funding sources varied across countries, which could influence the frequency and quality of A&F interventions. Nine out of 11 countries reported having a national antibiotic stewardship programme or policy, which aim to provide systematic support to ongoing AMS efforts and aid sustainability. Conclusions The survey identified gaps and opportunities for AMS efforts that include A&F across member countries in Europe, Canada and Australia. JPIAMR-PAAN will continue to leverage its members to produce best practice resources and toolkits for antibiotic A&F interventions in primary care settings and identify research priorities.

- BackgroundPrimary care is a critical partner for antimicrobial stewardship efforts given its high human antibiotic usage. Peer comparison audit and feedback (A & F) is often used to reduce inappropriate antibiotic prescribing. The design and implementation of A & F may impact its effectiveness. There are no best practice guidelines for peer comparison A & F in antibiotic prescribing in primary care.ObjectiveTo develop best practice guidelines for peer comparison A & F for antibiotic prescribing in primary care in high income countries by leveraging international expertise via the Joint Programming Initiative on Antimicrobial Resistance-Primary Care Antibiotic Audit and Feedback Network.MethodsWe used a modified Delphi process to achieve convergence of expert opinions on best practice statements for peer comparison A & F based on existing evidence and theory. Three rounds were performed, each with online surveys and virtual meetings to enable discussion and rating of each best practice statement. A five-point Likert scale was used to rate consensus with a median threshold score of 4 to indicate a consensus statement.ResultsThe final set of guidelines include 13 best practice statements in four categories: general considerations (n = 3), selecting feedback recipients (n = 1), data and indicator selection (n = 4), and feedback delivery (n = 5).ConclusionWe report an expert-derived best practice recommendations for designing and evaluating peer comparison A & F for antibiotic prescribing in primary care. These 13 statements can be used by A & F designers to optimize the impact of their quality improvement interventions, and improve antibiotic prescribing in primary care.
