Besides, the ndk gene has affected the apoptosis rate of A. veronii TH0426. These results would help to demonstrate the function of ndk further and realize the pathogenesis on A. veronii.Rare diseases are characterized by a substantial unmet need mostly because the majority have limited, or no treatment options and a large number also affect children. Appropriate animal models, based on the knowledge of the molecular pathology of the human disease, are a significant element to support the medical plausibility of an orphan designation during the development of orphan medicines for rare neurological diseases. This observational, retrospective study aims to investigate the clinical or nonclinical nature of data submitted to support medical plausibility of orphan designations in the EU (2001-2019), for a group of rare and paediatric neurological diseases. From our sample of 30 diseases, 70% are rare with paediatric onset and 37% have approved orphan designations. The use of nonclinical data was significantly higher than clinical data (65% vs. 35%, p = 0.013) to support medical plausibility. Examples of diseases, with orphan designations based only in nonclinical data, are also discussed Aicardi-Goutières syndrome and Centronuclear myopathy animal disease models, potentially used to support medical plausibility of medicines. Nonclinical appropriate models, assessing disease relevant endpoints, may contribute to increase the translational value of animal models, in paediatric and rare neurological area, to accelerate research and the effective development of treatment options.Ginseng (Panax ginseng) is commonly used in Asia as a medicinal herb. In particular, fermented ginseng, GBCK25, has been recently developed to increase ginsenoside absorption. It also has other beneficial biological effects such as hemodynamic and anti-inflammation functions. Here, we investigated the potential toxicity of GBCK25 in Sprague-Dawley rats following 13 weeks of GBCK25 treatment by oral gavage at doses of 250, 500, or 1000 mg/kg/day and reversible toxic effects over a 4-week recovery phase. Ten male and female rats per group were randomly allocated to the main toxicology groups and five male and female rats per group were allocated to the 0 and 1000 mg/kg/day recovery groups, respectively. There was no mortality; significant clinical toxicity or microscopic findings; and changes in body weight, food consumption, hematological parameters, serum biochemistry, or absolute and relative organ weights in any of the groups. In conclusion, there were no toxicological changes upon repeated oral gavage of GBCK25 at doses of 250, 500, or 1000 mg/kg/day in Sprague-Dawley rats over 13 weeks. The no-observed-adverse-effect level of GBCK25 was 1000 mg/kg/day in both sexes of Sprague-Dawley rat.Eucommia ulmoides Oliver is native to China and frequently used in traditional Chinese medicine formulations. However, studies show that Eucommia ulmoides extract (EUE) are potentially genotoxic and nephrotoxic. To evaluate its safety, the Ames test, bone marrow micronucleus assay and chromosomal aberration assay, along with acute (24 h) and sub-chronic (13 weeks) toxicity were conducted. EUE was non-genotoxic within the dose ranges of 0.0352-22 mg/plate (raw plant equivalent as below), 22-88 g/kg body weight and 2-20 mg/mL. The maximum tolerated dose of EUE was not less than 168 g/kg, which is 1260 times that of clinical doses in human adults. Long-term (13 weeks) administration led to dose-dependent increase in nephrotoxicity-related indices, and pathological changes in renal tissues. These changes were alleviated 5 weeks after ceasing the low dosage of 11.2 g/kg but persisted at the high dosage of 56 g/kg. Conclusively, EUE is non-genotoxic, and do not result in acute toxicity. However, long-term and high-dose administration can lead to partly reversible nephrotoxicity.Under the European chemicals legislation REACH (Registration, Evaluation, Authorisation and restriction of CHemicals), the use of chemicals posing an unacceptable risk for humans and the environment can be restricted. This requires that regulatory authorities of EU member states, or the European Chemicals Agency on request of the Commission, submit a restriction proposal in which they suggest one or multiple risk management options (RMOs). The options are recommended to be evaluated in a socio-economic analysis (SEA) using defined criteria. This paper explores the drivers of the selection of the preferred RMO in 32 restriction dossiers. Applying principal component analysis reveals that the selection of the preferred RMO, and the evaluation of possible trade-offs between alternative RMOs, is determined by criteria characterizing a measure's effectiveness and practicality, in particular its risk reduction capacity (R) and proportionality. A logistic regression using quantitative estimates provided in SEA suggests that the probability for an RMO to be selected is the higher the higher its R and the lower the costs of the restriction. Based on our analysis we conclude that the selection process of RMOs in REACH restriction dossiers could be strengthened by defining a limited but unambiguous set of criteria, conducting a score-based evaluation as a default, and by defining transparent decision rules.
Public Health England (PHE) developed an antimicrobial stewardship (AMS) surveillance system and conducted a national pilot to test the feasibility of centrally collecting data from AMS audits performed by NHS hospital trusts. The system was simplified, focusing on requirements of the NHS AMR CQUIN (Commissioning for Quality and Innovation; a financial incentive quality improvement scheme).

To present results and user feedback from the national pilot, and results from using the AMS surveillance system as part of the AMR CQUIN.

An AMS surveillance system was developed and a national pilot conducted in which 33 NHS trusts submitted data and feedback on system utilization. Entinostat The system was refined based on feedback and deployed nationally to collect AMS data for the 2016-17 AMR CQUIN.

Most trusts participating in the pilot collected data on documentation of indication (90%). Fewer collected data on documenting review decisions at 48-72 h (36%). On average 83% of patients had an indication documented, whereas 71% had formal documentation of 48-72 h review.
