COVID-19 has proven to be a formidable challenge for many countries in the European Union to manage effectively. The European Union has implemented numerous strategies to face emerging issues. Member States have adopted measures such as the closure of borders and significant limitations on the mobility of people to mitigate the spread of the virus. An unprecedented crisis coordination effort between Member States has facilitated the ability to purchase equipment, personal protective equipment, and other medical supplies. Attention has also been focused on providing substantive money for research to find a vaccine and promote effective treatment therapies. Financial support has been made available to protect worker salaries and businesses to help facilitate a return to a functional economy. Lessons learned to date from COVID-19 in the European Union are many; the current crisis highlights the need to think about future pandemics from a population-based management approach and apply outside the box critical thinking. Due to the complexity, intensity, and frequency of complex disasters, global leaders in healthcare, government, and business will need to pivot from siloed approaches to decision-making to embrace multidisciplinary and transdisciplinary levels of cooperation. This cooperation requires courage and leadership to recognize that changes are necessary to avoid making the same mistakes we have planned countless times on avoiding. This study focuses on the European Union’s initial response to the COVID-19 pandemic, starting with how the European Union first learned and processed the global information arising out of China, followed by the incremental population-based medicine/management decisions made that currently are defining the European Union’s capacity and capability. The capacity to organize, deliver, and monitor care to a specific clinical population under a population-based management target includes strict social distancing strategies, contact testing and tracing, testing for the virus antigen and its antibodies, isolation, and treatment modalities such as new mitigating medications, and finally, a vaccine.

This review presents the basic problems and currently available molecular techniques used for genetic profiling in disaster victim identification (DVI). The environmental conditions of a mass disaster often result in severe fragmentation, decomposition and intermixing of the remains of victims. In such cases, traditional identification based on the anthropological and physical characteristics of the victims is frequently inconclusive. This is the reason why DNA profiling became the gold standard for victim identification in mass-casualty incidents (MCIs) or any forensic cases where human remains are highly fragmented and/or degraded beyond recognition. The review provides general information about the sources of genetic material for DNA profiling, the genetic markers routinely used during genetic profiling (STR markers, mtDNA and single-nucleotide polymorphisms [SNP]) and the basic statistical approaches used in DNA-based disaster victim identification. Automated technological platforms that allow the simultaneous analysis of a multitude of genetic markers used in genetic identification (oligonucleotide microarray techniques and next-generation sequencing) are also presented. Forensic and population databases containing information on human variability, routinely used for statistical analyses, are discussed. The final part of this review is focused on recent developments, which offer particularly promising tools for forensic applications (mRNA analysis, transcriptome variation in individuals/populations and genetic profiling of specific cells separated from mixtures).

The recent clinical trials provided evidence both in favor and against the importance of Cr in healthy and ill organisms. Unfortunately, also the molecular mechanism by which chromium affects glucose and lipid metabolism is still unclear. Beneficial effects of diet supplementation with different sources of Cr³⁺ can be potentially explained by rather pharmacological than nutritional effects.

The number of fatal accidents and severe injuries, resulting from road accidents, may be reduced through applying an integrated approach to safety on roads. The strategies and programmes for improving road traffic should include the following measures: reducing the risk of exposure to an accident, prevention of accidents, reduction in bodily injuries sustained in accidents, and reduction of the effects of injuries by improvement of post-accident medical care.

The preparedness of a hospital for mass-casualty incident and disaster response includes activities, programs and systems developed and implemented before the event. These measures are designed to provide the necessary medical care to victims of disasters, and to minimize the negative impact of individual events on medical services. Up until now, there has been no systematic survey in Poland concerning the readiness of hospitals, as well as medical personnel, to deal with mass-casualty incidents. Consequently, little is known about the knowledge, skills, and professional competences of healthcare workers. The objective of this pilot study was to start an exploration and to collect data on the competences of healthcare workers, in addition to assessing the preparedness of hospitals for mass-casualty incidents. Utilizing an anonymous survey of a random sample, 134 healthcare providers were asked to respond to questions about the competencies they needed, and hospital preparedness during disaster response. It turned out that the test subjects evaluate their own preparedness for mass-casualty incidents and disasters better than the preparedness of their current place of work. The pilot study demonstrated that a properly designed questionnaire can be used to assess the relationship between hospital and staff preparedness and disaster response efficiency. Evaluation of the preparedness and effectiveness of disaster response is a means of finding and removing possible gaps and weaknesses in the functioning and effective management of a hospital during mass-casualty incidents.
