Background: Good laboratory practices in terms of biosecurity and biosafety are essential for the protection of laboratory personnel, the populations and the environment. If not implemented, the risk of pathogen spreading from the laboratory is conceivable. In addition, in current African geopolitical context, the reliable practices such as the protection, control and tracking of valuable biological material will prevent their loss, theft, uncontrolled access and potential misuse. WAHO, with the support of KfW is implementing trainings of trainers on biosecurity in the ECOWAS region in a project called PROALAB. PROALAB team realized that many partners were aiming at implementing in parallel quite similar non internationally certified programs in the ECOWAS region. Therefore, PROALAB decided to organize a meeting of key stakeholders in order to pool efforts, avoid duplication, and harmonize strategies and procedures. Objective: Develop a harmonized strategy and harmonized procedures for the training of health professionals in biosecurity/biosafety and biohazard risk management in ECOWAS member countries to pass internationally certified biosafety and biosecurity examinations. Methods: Programs of each of the institutions were presented and discussed. A regional program on biosecurity/biosafety training was elaborated during group working and a regional program of certification of trainers was discussed and validated. A work plan and timeline were developed through group working. Results: In the ECOWAS region, some countries are more advanced in biosecurity training. Training is generally organized by national biosecurity associations with the support of the IFBA or other partners (WHO, FMx, PHE, etc.). Côte d’Ivoire, Nigeria and Mali seem more advanced and could be solicited to organize training for less-advanced countries. The IFBA certification covers five domains: (1) Biorisk management, (2) biosecurity, (3) biosafety cabinet, (4) biological waste management and (5) biocontainment facility. The technical working group decided consensually that basic training for biosecurity managers in the laboratories should cover the first two domains. More advanced experts advising governments should be trained in the other domains progressively. Progressive training could be built on the 3 levels Nigerian/Ivoirian system of “basic-advanced-consolidated (or expert)” system. Existing module from WHO, FMx, IPD, IPCI and other ECOWAS countries should be adapted to match the international certification needs. Practical training should also be organized in the laboratory by the same institutions that will be allowed to deliver a practical certificate on behalf of WAHO. Conclusion: With the extension of laboratory activities in the context of strengthening the surveillance programs in the ECOWAS region, more expertise on biosecurity is needed. With the support of national biosecurity associations, WAHO could play a role in harmonizing reinforcing training on biosecurity and legislation.

In this article, cholesterol 3-hemisuccinate (CHS) was synthesized through the functionalization of the end group of liquid crystal monomer cholesterol with succinic anhydride. Hydrophobic cholesterol modified low molecular weight chitosan (CS-CH) was synthesized by 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC)-mediated coupling reaction. Chemical structure, crystalline morphology, and thermal properties of the biological material were characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetric (DSC), and polarized light microscopy (POM). The results of POM showed that CHS was a kind of crystalline material with liquid crystal property of cholesterol. DSC showed that the melting point and the crystalline temperature of CHS were 188 °C and 145 °C respectively. DSC also showed that CS-CH was a kind of thermoplastic biological material. The max melting temperature decreased from 120 °C to 110 °C with increasing the weight ratio of EDC/CHS to chitosan.

Abstract. Biological particles such as bacteria, fungal spores or pollen are known to be efficient ice nucleating particles. Their ability to nucleate ice is due to ice nucleation active macromolecules (INMs). It has been suggested that these INMs maintain their nucleating ability even when they are separated from their original carriers. This opens the possibility of an accumulation of such INMs in soils, resulting in an internal mixture of mineral dust and INMs. If particles from such soils which contain biological INMs are then dispersed into the atmosphere due to wind erosion or agricultural processes, they could induce ice nucleation at temperatures typical for biological substances, i.e., above −20 up to almost 0 °C, while they might be characterized as mineral dust particles due to a possibly low content of biological material. We conducted a study within the research unit INUIT (Ice Nucleation research UnIT), where we investigated the ice nucleation behavior of mineral dust particles internally mixed with INM. Specifically, we mixed a pure mineral dust sample (illite-NX) with ice active biological material (birch pollen washing water) and quantified the immersion freezing behavior of the resulting particles utilizing the Leipzig Aerosol Cloud Interaction Simulator (LACIS). A very important topic concerning the investigations presented here as well as for atmospheric application is the characterization of the mixing state of aerosol particles. In the present study we used different methods like single-particle aerosol mass spectrometry, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray analysis (EDX), and a Volatility–Hygroscopicity Tandem Differential Mobility Analyser (VH-TDMA) to investigate the mixing state of our generated aerosol. Not all applied methods performed similarly well in detecting small amounts of biological material on the mineral dust particles. Measuring the hygroscopicity/volatility of the mixed particles with the VH-TDMA was the most sensitive method. We found that internally mixed particles, containing ice active biological material, follow the ice nucleation behavior observed for the pure biological particles. We verified this by modeling the freezing behavior of the mixed particles with the Soccerball model (SBM). It can be concluded that a single INM located on a mineral dust particle determines the freezing behavior of that particle with the result that freezing occurs at temperatures at which pure mineral dust particles are not yet ice active.

Critical Timing

The application of Value-based Healthcare requires not only the identification of key processes in the clinical domain but also an adequate analysis of the value chain delivered to the patient. Data Science and Big Data approaches are technologies that enable the creation of accurate systems that model reality. However, classical Data Mining techniques are presented by professionals as black boxes. This evokes a lack of trust in those techniques in the medical domain. Process Mining technologies are human-understandable Data Science tools that can fill this gap to support the application of Value-Based Healthcare in real domains. The aim of this paper is to perform an analysis of the ways in which Process Mining techniques can support health professionals in the application of Value-Based Technologies. For this purpose, we explored these techniques by analyzing emergency processes and applying the critical timing of Stroke treatment and a Question-Driven methodology. To demonstrate the possibilities of Process Mining in the characterization of the emergency process, we used a real log with 9046 emergency episodes from 2145 stroke patients that occurred from January 2010 to June 2017. Our results demonstrate how Process Mining technology can highlight the differences between the flow of stroke patients compared with that of other patients in an emergency. Further, we show that support for health professionals can be provided by improving their understanding of these techniques and enhancing the quality of care.
