The aim of this paper is to study the effects of the spread of the COVID-19 virus in different regions and its impact on the economy and regional tourist flows. To this end, the researchers have been guided by a set of propositions which they have tried to demonstrate with the results obtained. This research shows that the impact of the pandemic is still being evaluated. The analysis of the relationship between the tourism sector and the pandemic outbreak in Spain provides an instructive case study to assist tourism in its recovery process. The paper delves into the impacts on the main Spanish touristic regions during the pandemic and providing implications for tourism recovery. In Spain, the tourism sector is of major economic importance, becoming one of the most vulnerable countries when crisis affects this industry. The negative image of the country due to the high infection rates has had a negative impact on travel and tourism. The Balearic Islands have been the most affected region with an 87% decrease in tourist visitors. The trips made by Spanish residents inside the Spanish territory shows the first increase found in the series analyzed. Domestic tourism not only represents an opportunity for all regions in this critical situation, but the types of accommodation also play a key role.

CYP2D6 genotype and debrisoquine metabolic ratio (MR) were analyzed in 133 Nicaraguan Mestizos (NMs) and 260 Cubans divided into Cuban Mestizos (CMs) and White Cubans (WCs). The frequencies of poor metabolizers (MR12.6) were 6% in NMs, 3.9% in CMs and 5.3% in WCs. The frequencies of ultrarapid metabolizers (MR0.1) were 0% in NMs, 2.3% in CMs and 5.3% in WCs. Mean (±s.d.) MR among extensive metabolizers (MR<12.6) was higher in NMs (1.5±1.6; n=118) than in CMs (1.0±1.3; n=124; P<0.001) and WCs (0.7±1.0; n=124; P<0.001). MR correlated with the 'activity score' of CYP2D6 genotypes (P<0.05; r=-0.55). Mean MR was higher among NMs than WCs and CMs for groups classified as 1 (P<0.05) or 2 (P<0.01) 'activity score'. In addition, mean (±s.d.) MR was higher among subjects carrying CYP2D6*17 than in CYP2D6 wt/wt (P<0.001). The CYP2D6*10 allele was higher in NMs (3.1%) than in CMs (0.8%; P<0.05) and WCs (0.4%; P<0.05). CYP2D6*17 allele was higher in CMs (10.2%) than WC (2.7%; P<0.005) and NMs (0%). Thus, the variability in CYP2D6 phenotypes found may be related to differences in allele frequency among groups (that is, CYP2D6*10 and *17 highest in NMs and CMs, respectively). However, the influence of environmental factors or alleles different than those studied here cannot be ruled out.

Unsustainable models of governance belonging to a widespread neoliberal mindset in developed countries have commonly been applied in the tourism industry. The management of the COVID-19 pandemic crisis has provided exemplary lessons regarding the application of sustainable models of governance. Through a participatory research, guidances are provided to tackle the COVID-19 effects in the tourist sector, namely in the Spanish southwestern region of Sierra de Gata. Seventeen indicators are proposed to enhance the safety measures, commitment of tourist authorities, communities empowered and protection of common resources among tourism industry, tourist authority and communities to spread cooperative awareness, mutual trust and shared objectives. Using a sample of 161 tourism companies, we tested a model of tourism governance with two focus groups during May and October 2020. Structural equation modelling (SEM) was utilized. Based on the data attained from a questionnaire and interviews, a sustainable tourism model to recover the threatened tourism sector is proposed. Indeed, our results can be used to draw theoretical and practical conclusions such as 1.) connecting private and public interactions to tackle the spread of the virus and strategies to recover the damaged tourist sector, 2.) to develop corporative values among the tourist industry and communities, 3.) to enhance governance models (trusts, consortia, tourist boards, clusters) to promote cooperation, 4.) to improve the local participation of companies, communities and associations in decision-making, and 5.) to prioritize qualitative development goals over quantitative ones, in the touristic territory. These conclusions are applicable to other regions suffering from the damaging consequences of the pandemic.

Abstract:The purpose of the study is to assess whether Corporate Social Responsibility regarding water is considered relevant for sustainability in companies related to agriculture in South Africa, considering that their impact directly influences public access to water. To accomplish this purpose, a qualitative approach was developed through the study of the 22 existing companies from the agriculture sector, food and beverages, forest and paper production, and Tobacco, which published their last integrated report within the Global Reporting Initiative framework. A thematic content analysis was carried out, involving the analysis of the written sustainability reports. For data analyses, ATLAS.ti 7.1 software was used to match the main aspects related to water management. Pragmatic advice for practitioners derives from the research results, considering that Corporate Social Responsibility in general-and sustainable water management in particular-represents an opportunity for companies to get competitive advantages in the market. The study also determines the best practices in the field in South Africa with benchmarking purposes.

Ethnicity is one of the major factors involved in interindividual variability to drug response. This study aims to describe the frequency of the most relevant pharmacogenetic biomarkers and metabolic phenotypes in Central American healthy volunteers and to determine its interethnic variability. Twenty-six original research articles on allelic, genotypes or metabolic phenotype frequencies were analyzed, in which a total number of 7611 Central American healthy volunteers were included (6118 were analyzed for genotype and 1799 for metabolic phenotype). No reports were available for population from Belize and Honduras. The CYP2D6*4 and *5 frequencies in Amerindian populations from Costa Rica have shown to be among the highest frequencies so far reported in the world. Furthermore, NAT2*5 and *6 presented higher frequencies in admixed populations than in Amerindians, but, inversely, the NAT2*7 was more frequent in Amerindians compared to an admixed population. Likewise, different patterns of distribution have been shown in HLA-A*02, *03 and HLA-B*07 among Native populations from Latin America. Reports on Central American populations were also found for the CYP2C19, LDLR, CYP2E1, MDR1, G6PD, TP53, CYP1A2, CYP3A4 and CYP3A5 biomarkers, but no data were available for the other 91 pharmacogenetic biomarkers revised in Central American populations. Differences in the frequency of some pharmacogenetic biomarkers and metabolic phenotypes were found, showing interethnic variability within Central American and with other Latin American populations.
