The samples used in this analysis were obtained by two extraction methods: hot extraction and cold extraction. If a microbial load of samples was found, the same extracts were filtered using sterile 0.22 μm pore size filters from PES (Polyester) for decontamination. The working methodology was based on the Standard SR EN ISO 21149/2017 which provides general guidelines for counting and detecting mesophilic aerobic bacteria using as a medium for isolation, cultivation and counting of microorganisms (bacteria and fungi) the non-differential environment. The experimental results obtained showed microbial contamination of all samples. The level of microbial contamination is different for the extracts taken under study, depending on the type of coffee used, green or roasted, but also on other conditions, such as wet or dry processing. Roasted coffee is much less contaminated compared to green coffee, due to a thermal (incomplete) sterilization by the roasting procedure. The working conditions used, the temperature of the distilled water used to prepare the extracts, their non-sterile handling, but also the type of coffee used, are the factors that determined the microbial contamination.","PeriodicalId":11935,"journal":{"name":"European Journal of Medicine and Natural Sciences","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77845866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chito-oligosaccharides (CHOS) are described as homo- or heterooligomers of N-acetylglucosamine and D-glucosamine. As a starting material for CHOS production chitin or chitosan can be used. When it comes to the medical field, there are indications that CHOS may be developed and used as drugs against asthma, antibacterial agents, ingredients in wound-dressings and vectors in gene-therapy. The methods of production can rely on enzymatic conversions, chemical methods or combinations of these methods. There is ample literature concerning the biological effects of chitosans, but relatively little is known about the effects of CHOS, and the mechanisms behind observed bioactivities are generally poorly understood. This review is focused on the characterization of chitin and chitosan by presenting the biological properties, and on the enzymatic production of CHOS, and on further separation and purification methods for producing well-defined mixtures and also provides an overview of some of the most promising applications of CHOS.","PeriodicalId":11935,"journal":{"name":"European Journal of Medicine and Natural Sciences","volume":"86 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83589315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Driven by an increase in availability of pharmaceutical opioids and by an increase in their consumption, specifically, for pain treatment, more so in the past twenty years, it has led to an economic cost of prescription opioid abuse, overdose, and dependence in the United States estimated to be 78.5 billion USD. Methods: A thorough evaluation of the relevant extracted literature has been used to answer the question of the most effective ways to regulate health markets to decrease the opioid crisis in the United States, using keywords and phrases such as opioid epidemic in the US, prescription drug abuse, prescription medication abuse in US, medication misuse, cost-effective ways to health market regulation, drug monitoring programs, prescriber continuing education, provider continuing education, and pain management optimization. Results: Overcoming this epidemic nationwide requires improvement in patient utilization of and access to safe and effective treatment options for opioid abuse and overdose, addressing the stigma correlated with opioid use, considering appropriate use of abuse deterrent formulations (ADF) along with patient education, and improving prescribing practices via utilization of drug monitoring programs, CDC opioid prescribing guidelines and provider continuing education. Conclusion: Utilizing and implementing the aforementioned steps has shown to be a challenge. Further and repeated attempts are needed, while at the same time considering possible new steps that could help reinforce their utilization further.","PeriodicalId":11935,"journal":{"name":"European Journal of Medicine and Natural Sciences","volume":"431 1","pages":"7 - 15"},"PeriodicalIF":0.0,"publicationDate":"2021-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77812474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The starting point is the recognition that CoPs can contribute to build resilience among their members, and particularly moral resilience. Among others, this is due to the fact that they share a reflective space from which shared knowledge is generated, which can be a source of strength and trust within the healthcare team. Specifically, in extreme situations, the CoPs can contribute to coping with moral distress, which will be crucially important not only to facing crisis situations, but to prevent the long-term adverse consequences of working in conditions of great uncertainty. The purpose of this paper is to analyze how CoP can support healthcare professionals when building moral resilience. To support that goal, we will first define CoP and describe the main characteristics of communities of practice in healthcare. Subsequently, we will clarify the concept of moral resilience, and establish the relationship between CoP and moral resilience in light of the current COVID-19 pandemic. Finally, we analyze different group experiences that we can consider as CoP which emerged in the midst of the COVID-19 pandemic to navigate moral problems that arose.","PeriodicalId":11935,"journal":{"name":"European Journal of Medicine and Natural Sciences","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89757044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After the first cases reported in China, the disease has progressively widespread worldwide where all affected countries has adapted specific safety protocols and tried to find new therapies in order to face this new disease. The final objective is to evaluate the overall impact of stringency measures taken from Albanian and Italian governmental authorities in relation to daily cases of COVID-19 in each country. This is a descriptive paper where the data collected in Albania and Italy according to authority-based stringency measures were compared with their output; temporary trend of daily cases. Officially Albania reported the first COVID-19 case in 8th of March in an Albanian citizen just arrived from Italy, meanwhile in Italy the first cases dated January 31st were a Chinese couple in Rome who had travel from Wuhan City. Both governments took action by applying different closer measures; thereby Blavatnik School of Government has introduced the Oxford COVID-19 Government Response Tracker (OxCGRT) in order to quantifying numerically these actions. According to OxCGRT, Albania and Italy present similar level of stringency indicator, but epidemiological curve of daily cases is totally different in shape. Italian curve corresponds to a typical outbreak, while Albania curve seem like any endemic disease in the population. In front of this pandemic, the Albanian curve might be cut off as a result a small number of tests carried out by Albania authorities, 6906 tests/million population, which is far lower than tests performed by Italian authorities, which is 11 times fold (79908 test/million population). Toward end of May the number of COVID-19 were dropped so both governments planned to relief closure measures by opening most of public and economic activities. In front of the fear that COVID-19 could rise up again, as a result of virus transmission amongst people that was observed in Albania, while in Italy continued with the low and decreasing trend of disease cases. Data and their comparison though different indicators or index, shows that stringency measures could contribute on a temporary diminution of new cases of COVD-19, but if not are accompanied with individual protection measures, and/or special vulnerable groups it might be a missing opportunity because the general population might lose what was achieved during national quarantine. On the other hand, taking in consideration low public spending per capita in Albania (307 USD, 2014), moving from “hummer” toward “dance” phase, managing and supporting health system is critical. Public health services should be mainly the entitled authorities to monitor data and come up with specific and efficient measures in order to prevent an increase of cases on the overall population.Keywords: Albania, Italy, stringency index, epidemic, COVID-1","PeriodicalId":11935,"journal":{"name":"European Journal of Medicine and Natural Sciences","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76557136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although more than 80 species of coffee have been identified worldwide, only two are economically important. Coffea Arabica, also known as Arabica coffee, is responsible for about 70 percent of the world coffee market, and Coffea Canephora or Robusta coffee represents the rest. Due to the strong physiological effects of caffeine on human physiology, the caffeine content is a very important quality parameter of processed coffee. Routine analysis of caffeine in the food industry can be facilitated using fast and reliable tests. In this article, we quantitatively determined the caffeine content using the chloroform isolation method and we also performed the qualitative determination of caffeine in green coffee of Indian origin by the UV-VIS spectrophotometric method. Following the analysis of caffeine isolate with chloroform, we obtained a caffeine content of 182 mg / 100 g for the Robusta green coffee sample and 154 mg / 100 g for the Arabica green coffee sample. Thus we can confirm the presence of a higher caffeine content in the Robusta India green coffee sample than in the Arabica India green coffee sample. In the spectrophotometric analysis we used 4 coffee samples obtained by extraction with hot distilled water and by extraction with cold distilled water. The spectral analysis confirms the presence of caffeine in both studied coffee species and agrees with the data in the literature.","PeriodicalId":11935,"journal":{"name":"European Journal of Medicine and Natural Sciences","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83161171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
