[Cooperation according to French Law "hospital, patients, health and territories": Pharmacists' involvement in Aquitaine region].

In 2009, the French Act "Hospital, Patients, Health and Territories" (loi "Hôpital, Patients, Santé et Territoires") reorganized the outpatient care pathway and defined missions aimed at improving cooperation between pharmaceutical and medical professionals. Five years later, we conducted a survey among community pharmacists in order to assess the appropriation of these missions and the way cooperation was implemented. We also aimed to investigate factors that could hamper or ease the development of these activities in order to identify actions needed to improve pharmacists' involvement. In partnership with the local health authorities "Agence régionale de santé", we conducted a survey via an online questionnaire sent to pharmacy holders in July 2014 in Aquitaine region. Information was collected about the pharmacies, involvement in collaborative activities, and barriers to cooperation. Overall, 20% (249) of pharmacists responded to the survey. They owned predominantly rural pharmacies (46%) or neighborhood pharmacies (41%), with two pharmacists per pharmacy (48%). Regarding collaborative activities, the majority of pharmacists (78%) had conducted interviews with their patients taking vitamin K antagonist therapy and they were willing to continue (87%). The implication was less common concerning other actions such as referent pharmacist for nursing homes (19%) or activities relating to therapeutic educational programs for patients with chronic conditions (34%). The vast majority of respondents (85%) were not aware of opportunities to become a correspondent pharmacist. The main obstacles for engaging in these activities were the lack of time, lack of knowledge about these missions and the lack of remuneration. We identified differences in pharmacists' involvement in collaborative activities depending on selected characteristics of the pharmacies. The findings of this survey underlined pharmacists' acceptance of these missions and suggest that better information and appropriate remuneration could enhance commitment. Recent changes in the legal framework (establishment of "pharmaceutical fees", extension of the scope of pharmaceutical interviews) enable funding for collaborative practices between medical practitioners and pharmacists, thus encouraging better coordination in the patient care pathway

Comparison of governance approaches for the control of antimicrobial resistance: Analysis of three European countries

Policy makers and governments are calling for coordination to address the crisis emerging from the ineffectiveness of current antibiotics and stagnated pipe-line of new ones – antimicrobial resistance (AMR). Wider contextual drivers and mechanisms are contributing to shifts in governance strategies in health care, but are national health system approaches aligned with strategies required to tackle antimicrobial resistance? This article provides an analysis of governance approaches within healthcare systems including: priority setting, performance monitoring and accountability for AMR prevention in three European countries: England, France and Germany. Advantages and unresolved issues from these different experiences are reported, concluding that mechanisms are needed to support partnerships between healthcare professionals and patients with democratized decision-making and accountability via collaboration. But along with this multi-stakeholder approach to governance, a balance between regulation and persuasion is needed

Pharmacological levels of withaferin A (Withania somnifera) trigger clinically relevant anticancer effects specific to triple negative breast cancer cells

Withaferin A (WA) isolated from Withania somnifera (Ashwagandha) has recently become an attractive phytochemical under investigation in various preclinical studies for treatment of different cancer types. In the present study, a comparative pathway-based transcriptome analysis was applied in epithelial-like MCF-7 and triple negative mesenchymal MDA-MB-231 breast cancer cells exposed to different concentrations of WA which can be detected systemically in in vivo experiments. Whereas WA treatment demonstrated attenuation of multiple cancer hallmarks, the withanolide analogue Withanone (WN) did not exert any of the described effects at comparable concentrations. Pathway enrichment analysis revealed that WA targets specific cancer processes related to cell death, cell cycle and proliferation, which could be functionally validated by flow cytometry and real-time cell proliferation assays. WA also strongly decreased MDA-MB-231 invasion as determined by single-cell collagen invasion assay. This was further supported by decreased gene expression of extracellular matrix-degrading proteases (uPA, PLAT, ADAM8), cell adhesion molecules (integrins, laminins), pro-inflammatory mediators of the metastasis-promoting tumor microenvironment (TNFSF12, IL6, ANGPTL2, CSF1R) and concomitant increased expression of the validated breast cancer metastasis suppressor gene (BRMS1). In line with the transcriptional changes, nanomolar concentrations of WA significantly decreased protein levels and corresponding activity of uPA in MDA-MB-231 cell supernatant, further supporting its anti-metastatic properties. Finally, hierarchical clustering analysis of 84 chromatin writer-reader-eraser enzymes revealed that WA treatment of invasive mesenchymal MDA-MB-231 cells reprogrammed their transcription levels more similarly towards the pattern observed in non-invasive MCF-7 cells. In conclusion, taking into account that sub-cytotoxic concentrations of WA target multiple metastatic effectors in therapy-resistant triple negative breast cancer, WA-based therapeutic strategies targeting the uPA pathway hold promise for further (pre)clinical development to defeat aggressive metastatic breast cancer

Guidance on the Selection of Appropriate Indicators for Quantification of Antimicrobial Usage in Humans and Animals

An increasing variety of indicators of antimicrobial usage has become available in human and veterinary medicine, with no consensus on the most appropriate indicators to be used. The objective of this review is therefore to provide guidance on the selection of indicators, intended for those aiming to quantify antimicrobial usage based on sales, deliveries or reimbursement data. Depending on the study objective, different requirements apply to antimicrobial usage quantification in terms of resolution, comprehensiveness, stability over time, ability to assess exposure and comparability. If the aim is to monitor antimicrobial usage trends, it is crucial to use a robust quantification system that allows stability over time in terms of required data and provided output; to compare usage between different species or countries, comparability must be ensured between the different populations. If data are used for benchmarking, the system comprehensiveness is particularly crucial, while data collected to study the association between usage and resistance should express the exposure level and duration as a measurement of the exerted selection pressure. Antimicrobial usage is generally described as the number of technical units consumed normalized by the population at risk of being treated in a defined period. The technical units vary from number of packages to number of individuals treated daily by adding different levels of complexity such as daily dose or weight at treatment. These technical units are then related to a description of the population at risk, based either on biomass or number of individuals. Conventions and assumptions are needed for all of these calculation steps. However, there is a clear lack of standardization, resulting in poor transparency and comparability. By combining study requirements with available approaches to quantify antimicrobial usage, we provide suggestions on the most appropriate indicators and data sources to be used for a given study objective

Antimicrobial Stewardship from Policy to Practice: Experiences from UK Antimicrobial Pharmacists

Antimicrobial stewardship in the UK has evolved dramatically in the last 15 years. Factors driving this include initial central funding for specialist pharmacists and mandatory reductions in healthcare-associated infections (particularly Clostridium difficile infection). More recently, the introduction of national stewardship guidelines, and an increased focus on stewardship as part of the UK five-year antimicrobial resistance strategy, have accelerated and embedded developments. Antimicrobial pharmacists have been instrumental in effecting changes at an organizational and national level. This article describes the evolution of the antimicrobial pharmacist role, its impact, the progress toward the actions listed in the five-year resistance strategy, and novel emerging areas in stewardship in the UK

The Anti-Tumor Effect of HDAC Inhibition in a Human Pancreas Cancer Model Is Significantly Improved by the Simultaneous Inhibition of Cyclooxygenase 2

Pancreatic ductal adenocarcinoma is the fourth leading cause of cancer death worldwide, with no satisfactory treatment to date. In this study, we tested whether the combined inhibition of cyclooxygenase-2 (COX-2) and class I histone deacetylase (HDAC) may results in a better control of pancreatic ductal adenocarcinoma. The impact of the concomitant HDAC and COX-2 inhibition on cell growth, apoptosis and cell cycle was assessed first in vitro on human pancreas BxPC-3, PANC-1 or CFPAC-1 cells treated with chemical inhibitors (SAHA, MS-275 and celecoxib) or HDAC1/2/3/7 siRNA. To test the potential antitumoral activity of this combination in vivo, we have developed and characterized, a refined chick chorioallantoic membrane tumor model that histologically and proteomically mimics human pancreatic ductal adenocarcinoma. The combination of HDAC1/3 and COX-2 inhibition significantly impaired proliferation of BxPC-3 cells in vitro and stalled entirely the BxPC-3 cells tumor growth onto the chorioallantoic membrane in vivo. The combination was more effective than either drug used alone. Consistently, we showed that both HDAC1 and HDAC3 inhibition induced the expression of COX-2 via the NF-kB pathway. Our data demonstrate, for the first time in a Pancreatic Ductal Adenocarcinoma (PDAC) model, a significant action of HDAC and COX-2 inhibitors on cancer cell growth, which sets the basis for the development of potentially effective new combinatory therapies for pancreatic ductal adenocarcinoma patients.Peer reviewe

Patterns of antibiotic use in hospital-acquired infections.

BACKGROUND: Monitoring the use of antimicrobials in hospitalized patients is critical owing to the risk of resistance selection. This study aimed to describe the patterns of antimicrobial prescription for the most frequent healthcare-associated infections (HAIs) in France, relating drugs and microbiological data. METHODS: We used data from the 2017 point-prevalence survey of HAI and antimicrobial use in France, a large nationally representative sample survey of inpatients. We sought unambiguous correspondence between individual indications of antibiotic regimen and HAI sites to determine which molecules were directed towards which pathogen, considering its resistance profile. RESULTS: Among 75,698 adult patients from 401 hospitals, 5.1% had an active HAI and 4.3% were being treated for an HAI. The two most frequent antibiotic indications were lower respiratory tract (LRTI, 27.7%) and urinary tract infections (UTI, 18.4%). For LRTI, the most prescribed antibiotic was amoxicillin-clavulanic acid (27.6%) and most frequently isolated pathogens (each accounting for around 17% of isolates) were Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. Meticillin-resistant S. aureus LRTI was more likely to be treated with linezolid. For UTI, ofloxacin, ceftriaxone, amoxicillin/co-amoxiclav were most-prescribed (∼13% each) and E. coli predominantly isolated (52.0%). Extended-spectrum beta-lactamase-producing E. coli UTI were more likely treated by fosfomycin, pivmecillinam or ertapenem. CONCLUSIONS: This study provides a baseline of antimicrobial use in relation to microbiological information in patients with the most common HAIs. These results can serve to direct future efforts in antimicrobial stewardship. Our work could be extended to a broader population, notably in Europe where similar surveys have been conducted

Physical performance and glycemic control under SGLT-2-inhibitors in patients with type 2 diabetes and established atherosclerotic cardiovascular diseases or high cardiovascular risk (PUSH): Design of a 4-week prospective observational study.

Background Type 2 diabetes (T2D) is associated with limitation in physical performance. Results from animal studies report enhancement of physical performance in T2D rodents treated with sodium glucose cotransporter 2 inhibitors (SGLT2is). However, in human patients with T2D and established atherosclerotic cardiovascular disease (ASCVD) or high cardiovascular risk, the impact of guideline directed SGLT2i medication on physical performance has not been sufficiently examined. Objectives The main objectives of this study are thus firstly, to assess the changes in physical performance after 4 weeks of exercise therapy in patients with established ASCVD or high cardiovascular risk categorized into three groups according to their glycemic control at baseline. Secondly, to investigate the association of glycemic control at baseline and new guideline directed antidiabetic treatment (inadequate glycemic control and diabetes + new SGLT2i vs. adequate glycemic control and diabetes vs. no diabetes) with change in physical performance. Methods and design This is a 4-week prospective observational study of 450 participants with established ASCVD or high cardiovascular risk with or without T2D and without previous SGLT2i medication undergoing exercise therapy during inpatient rehabilitation in a single center in Switzerland. Upon admission, participants are categorized into 3 groups of 150 participants each according to their glycemic control. Group I consisting of participants with inadequately controlled T2D defined as mean fasting plasma glucose (FPG) of ≥7 mmol/L, who are consequently administered new treatment with an SGLT2i. Group II comprises of participants with adequately controlled T2D with mean FPG of <7 mmol/L requiring no antidiabetic medication change. Group III consists of participants with no diabetes and mean FPG of ≤ 5.5 mmol/L. Primary outcomes are 6-min walk distance and rate of perceived exertion. Secondary outcomes are echocardiographic parameters (left ventricular mass index; global longitudinal strain average; end-diastolic volume), fatigue, muscle, metabolic, and anthropometric measures. Ethics and dissemination This study is conducted in accordance with the Declaration of Helsinki with ethical approval from the Cantonal Ethical Commission of Bern, Switzerland. The results will be published in a peer-reviewed journal. The implementation and reporting will be according to the SPIRIT guidelines.
