In several regions, healthcare systems have collapsed whereas interventions applied to slow the viral spreading have had major social and economic impacts. After China, Europe, and the United States, Latin America has emerged as the new epicenter of the pandemic. By late-June, the region accounted for roughly 50% of global daily deaths (Gardner, 2020). The evolution of the COVID-19 pandemic in the region has been heterogenous as several countries are currently experiencing exponential growth of their daily cases and fatalities, while others have successfully controlled their corresponding outbreaks. Cuba confi rmed its fi rst COVID-19 cases in mid-March. After a three-month outbreak, the country recently began to move to a post-epidemic phase. This dispatch details some relevant aspects of the strategy deployed in Cuba to face the COVID-19 pandemic and to decrease the impact of this emerging disease in the country. In addition, it describes the evolution of some epidemiological variables which allowed the country to de-escalate some of the non-pharmaceutical interventions applied during the outbreak.</p>","PeriodicalId":49835,"journal":{"name":"Medicc Review","volume":"22 3","pages":"64-68"},"PeriodicalIF":2.1,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38277721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is vitally important for government health authorities and leaders to have reliable estimates of infected cases and deaths in order to apply the necessary measures with the resources at their disposal. OBJECTIVE Test the validity of the logistic regression and Gompertz curve to forecast peaks of confi rmed cases and deaths in Cuba, as well as total number of cases. METHODS An inferential, predictive study was conducted using lo-gistic and Gompertz growth curves, adjusted with the least squares method and informatics tools for analysis and prediction of growth in COVID-19 cases and deaths. Italy and Spain-countries that have passed the initial peak of infection rates-were studied, and it was inferred from the results of these countries that their models were ap-plicable to Cuba. This hypothesis was tested by applying goodness-of-fi t and signifi cance tests on its parameters.RESULTS Both models showed good fi t, low mean square errors, and all parameters were highly signifi cant. CONCLUSIONS The validity of models was confi rmed based on logis-tic regression and the Gompertz curve to forecast the dates of peak infections and deaths, as well as total number of cases in Cuba.

Aging itself is a complex biological phenomenon characterized in part by changes in the immune system known as \"immunosenescence\", which makes older adults more susceptible to infectious, cardiovascular and autoimmune diseases, as well as cancers. Several strategies have been proposed in an attempt to reverse immunosenescence, including use of hormones, cytokines and thymic factors. A promising drug in the search to restore the thymic microenvironment (which plays an important role in the regulation and maintenance of the immune system) in older adults is Biomodulina T, a Cuban product registered for use in patients with recurrent respiratory infections. The administration of Biomodulina T increases the number of naïve T-lymphocyte, CD4-positive cells that have recently migrated from the thymus gland (recent thymic emigrants) and memory CD8-positive T lymphocytes, which have characteristics akin to stem cells (stem cell-like memory). Furthermore, the expression of programmed cell death 1 protein in CD4-positive T lymphocytes and CD4-positive T lymphocytes decreases, and the proliferative capacity of CD4-positive T lymphocytes increases, without changes in the frequency of regulatory T lymphocytes. These results suggest that the administration of Biomodulina T could be used to restore immunity in older adults and in other immunocompromised individuals, improve response to other immunotherapies in cancer patients, and increase the effi cacy of vaccinations in older adults. Its use has been approved in Cuba for immune system restoration.KEYWORDS Immunosenescence, aging, immunotherapy, immuno-modulation, antineoplastic protocols, Cuba.</p>","PeriodicalId":49835,"journal":{"name":"Medicc Review","volume":"22 3","pages":"54-56"},"PeriodicalIF":2.1,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38277717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epidermal growth factor (EGF) reduction is one of the molecular pillars of diabetic ulcer chronicity, thus EGF administration may be considered a type of replacement therapy. Topical EGF ad-ministration to improve and speed wound healing began in 1989 on burn patients as part of an acute-healing therapy. Further clinical studies based on topically administering EGF to different chronic wounds resulted in disappointing out-comes. An analysis of the literature on unsuccessful clinical trials identifi ed a lack of knowledge concerning: (I) molecular and cellular foundations of wound chronicity and (II) the phar-macodynamic requisites governing EGF interaction with its receptor to promote cell response. Yet, EGF intra- and perile-sional infi ltration were shown to circumvent the pharmacody-namic limitations of topical application. Since the fi rst studies, the following decades of basic and clinical research on EGF therapy for problem wounds have shed light on potential uses of growth factors in regenerative medicine. EGF's molecular and biochemical effects at both local and systemic levels are diverse: (1) downregulation of genes encoding infl ammation mediators and increased expression of genes involved in cell proliferation, angiogenesis and matrix secretion; (2) EGF in-tervention positively impacts both mesenchymal and epithelial cells, reducing infl ammation and stimulating the recruitment of precursor circulating cells that promote the formation of new blood vessels; (3) at the subcellular level, upregulation of the EGF receptor with subsequent intracellular traffi cking, includ-ing mitochondrial allocation along with restored morphology of multiple organelles; and (4) local EGF infi ltration resulting in a systemic, organismal repercussion, thus contributing to attenuation of circulating infl ammatory and catabolic reac-tants, restored reduction-oxidation balance, and decreased toxic glycation products and soluble apoptogenic effectors. It is likely that EGF treatment may rearrange critical epigenetic drivers of diabetic metabolic memory.
