In this regard, microbial bioactive compounds with characteristics such as optimal compatibility and close interaction with the host immune system are considered a novel therapeutic approach. The fermentation process is one of the most well-known pathways involved in the natural synthesis of a diverse range of postbiotics. However, some postbiotics are a type of probiotic response behavior to environmental stimuli that usually play well-known biological roles. Also, postbiotics with unique structure and function are key mediators between intestinal microbiota and host cellular processes/metabolic pathways that play a significant role in maintaining homeostasis. By further understanding the nature of parent microbial cells, factors affecting their metabolic pathways, and the development of compatible extraction and identification methods, it is possible to achieve certain formulations of postbiotics with special efficiencies, which in turn will significantly improve the performance of health systems (especially in developing countries) toward a wide range of acute/chronic diseases. The present review aims to describe the fundamental role of postbiotics as the key mediators of the microbiota-host interactions. Besides, it presents the available current evidence regarding the interaction between postbiotics and host cells through potential cell receptors, stimulation/improvement of immune system function, and the enhancement of the composition and function of the human microbiome.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79977643","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 development of economic activities for the production, exploitation and export of agricultural products, minerals and raw materials demanded in the international market, favored the necessary conditions for the emergence, expansion, resurgence and persistence of the endemic epidemic of malaria in the different stages studied. A common and fundamental element in the different defined historical moments was the importance given to malaria as an economic problem due to the negative externalities it imposed on the labor force. In addition, due to the role it played as a barrier that limited the exploitation of natural resources and raw materials of interest; as well as the impact that it caused to the flow and commercial exchange. The previous situation was framed with the growth, consolidation and geostrategic expansion of the United States, as the main commercial partner of the region, and its interest in the exploitation of resources and raw materials, cheap labor, the need to create new markets, which coincided with the goals of modernization and economic strengthening of Colombia. Taking into account different relevant milestones that occurred in the 1848-2019 period, the following stages were defined: Epidemiological emergence and re-emergence of tropical fevers in places of economic exploitation, 1848-1899;Emergence of a new paradigm, control in enclaves of economic interest, ports and cities, 1900-1949;Control to eradication, intensified control-eradication, prevention and control, 1950-1999;Prevention, control and elimination of malaria, 2000-2019. Historically, antimalarial control initiatives in the country have been directed, restricted and prioritized in places of political and economic importance. The technical-scientific intervention measures implemented in the different stages studied have been uncritically replicated without adapting to the epidemiological scenarios existing in the country. Finally, the antimalarial control measures implemented in Colombia have been imported and adopted from international health initiatives as a result of commitments and obligations acquired in the global commercial context.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88433317","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}

Because of weaker health-care systems, existing comorbidities burden (HIV, malaria, tuberculosis, and non-communicable conditions), and poor socioeconomic determinants, initial predictive models had forecast a disastrous impact of COVID-19 in Africa in terms of transmission, severity, and deaths. Nonetheless, current epidemiological data seem not to have matched expectations, showing lower SARS-CoV-2 infection and fatality rates compared to Europe, the Americas and Asia. However, only few studies were conducted in low- and middle-income African settings where high poverty and limited access to health services worsen underlying health conditions, including endemic chronic infectious diseases such as HIV and tuberculosis. Furthermore, limited, and heterogeneous research was conducted to evaluate the indirect impact of the pandemic on general health services and on major diseases across African countries. International mitigation measures, such as resource reallocation, lockdowns, social restrictions, and fear from the population have had multi-sectoral impacts on various aspects of everyday life, that shaped the general health response. Despite the vast heterogeneity of data across African countries, available evidence suggests that the COVID-19 pandemic has severely impacted the control and prevention programs, the diagnosis capacity and the adherence to treatment of major infectious diseases (HIV, TB, and Malaria) - including neglected diseases - and non-communicable diseases. Future research and efforts are essential to deeply assess the medium- and long-term impact of the pandemic, and to implement tailored interventions to mitigate the standstill on decades of improvement on public health programs.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85965204","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 Greek society and economy were dislocated as a result of plundering of the country's vital resources, as well as enforced payments, instead paid to the occupying forces. The dramatic food shortages and famine appeared plaguing especially large cities. There is very limited information on the trends of mortality and morbidity (1941-1944) at a national level. The morbidity and mortality statistics of the General Statistical Service of Greece were assessed and the incidence morbidity and mortality rates have been calculated. As denominator population we used the population of Greece according to 1940 census. The morbidity due to exanthematic typhus, typhoid fever, dysentery and meningitis has been elevated over the period 1940-1944. An elevated specific mortality due to tuberculosis, malaria and typhoid fever was observed over the period 1940-1941. Regarding non-communicable diseases, the mortality due to hemorrhagic stroke was increased after 1940. In conclusion, we found that the Axis/Nazi military occupation of Greece had considerable health effects on infectious diseases and hemorrhagic stroke mortality. Deaths ostensibly due to infectious diseases (e.g. tuberculosis or malaria), were expedited by the hunger famine of the period under investigation. With regard to the elevated mortality due to hemorrhagic stroke, we believe that the stressful events of occupation and famine have triggered increased psychosocial stress which in turn may have increased the risk of hemorrhagic stroke mortality during the period of Axis/Nazi occupation of Greece.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80048213","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 scientific community made progress in understanding risk factors, pathophysiology, clinical manifestations, diagnosis and treatment of acute SARS-CoV-2 infection. In the last months, another condition has become evident and caught the attention of the scientific community: the so-called long COVID syndrome. The pathophysiology of this condition is not known, even if some hypothesis have been made but not demonstrated yet. Long COVID is characterized by a very heterogeneous group of subacute and/or chronic symptoms and signs that follow the acute phase of SARS-CoV-2 infection and have a very variable duration. The presence of this syndrome in an individual is not dependent from the severity of the acute SARS-CoV-2 infection. Because of the extreme clinical heterogeneity, and also due to the lack of a shared and specific definition of the disease, it is very difficult to know the real prevalence and incidence of this condition. Some risk factors for the development of the disease have been identified: advanced age, elevated body mass index, comorbidities, specific symptoms of acute COVID-19 (in particular dyspnea), number of symptoms in the acute phase and female sex. The number of individuals affected by long COVID is high, even if it occurs only in a part of the subjects who had COVID-19. Therefore, long COVID constitutes now a major health issue and has to be managed in order to ensure an adequate access to care for all the people that need it. \"Post COVID\" clinics have been created in various countries, especially in Europe, for the management of people affected by long COVID syndrome. Guidelines have been written to help clinicians. An important role in the management of long COVID patients is played by the general practitioner, directly or indirectly linked to post COVID hospital clinics. The extreme heterogeneity of clinical presentation needs a patient-tailored, multidisciplinary approach. As NHS guidelines say, the three principal of care for long COVID patients are personalized care, multidisciplinary support and rehabilitation. More studies are needed in order to know better the pathophysiology of the disease. It is also necessary to create standardized and shared definitions of the disease, in order to better understand the epidemiology, the diagnostic criteria and to offer the right treatment to all the individuals who need it, without social or economic diffeences.","PeriodicalId":17977,"journal":{"name":"Le infezioni in medicina : rivista periodica di eziologia, epidemiologia, diagnostica, clinica e terapia delle patologie infettive","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81941732","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}
