In 2022, the 22nd International Conference on Aquatic Invasive Species returned to Europe as a hybrid event. The conference welcomed representatives from 41 countries, including the largest group of students and early career professionals of any ICAIS conference. The theme of the conference was "Global Climate Change Amplifies Aquatic Invasive Species Impacts." Keynote speakers discussed ongoing invasions and the damaging synergy between climate change and invasions, presented on the value of risk assessment, outreach, and education, highlighted new ways to estimate the economic costs of invasions, and told attendees about some of the work of NGOs in managing invasions. This special issue includes a selection of papers that were presented at the conference, along with a few related papers that were not presented which touch on the risk of specific vectors, improvements in survey techniques to detect new or spreading invaders, and advances in management approaches to control AIS.

Background: Amyotrophic lateral sclerosis (ALS) is a highly debilitating neurodegenerative condition. Despite recent advancements in understanding the molecular mechanisms underlying ALS, there have been no significant improvements in therapeutic options for ALS patients in recent years. Currently, there is no cure for ALS, and the only approved treatment in Europe is riluzole, which has been shown to slow the disease progression and prolong survival by approximately 3 months. Recently, tauroursodeoxycholic acid (TUDCA) has emerged as a promising and effective treatment for neurodegenerative diseases due to its neuroprotective activities. Methods: The ongoing TUDCA-ALS study is a double-blinded, parallel arms, placebo-controlled, randomized multicenter phase III trial with the aim to assess the efficacy and safety of TUDCA as add-on therapy to riluzole in patients with ALS. The primary outcome measure is the treatment response defined as a minimum of 20% improvement in the ALS Functional Rating Scale-Revised (ALSFRS-R) slope during the randomized treatment period (18 months) compared to the lead-in period (3 months). Randomization will be stratified by country. Primary analysis will be conducted based on the intention-to-treat principle through an unadjusted logistic regression model. Patient recruitment commenced on February 22, 2019, and was closed on December 23, 2021. The database will be locked in September 2023. Discussion: This paper provides a comprehensive description of the statistical analysis plan in order to ensure the reproducibility of the analysis and avoid selective reporting of outcomes and data-driven analysis. Sensitivity analyses have been included in the protocol to assess the impact of intercurrent events related to the coronavirus disease 2019. By focusing on clinically meaningful and robust outcomes, this trial aims to determine whether TUDCA can be effective in slowing the disease progression in patients with ALS. Trial registration: ClinicalTrials.gov NCT03800524. Registered on January 11, 2019. [ABSTRACT FROM AUTHOR]

This paper analyses the volatility transmission between European Global Systemically Important Banks (GSIBs) and implied stock market volatility. A Dynamic Conditional Correlation Generalized Autoregressive Conditional Heteroskedasticity model is applied to determine the dynamic correlation between returns of Europe's GSIBs and the world's most prominent measure of market "fear", the CBOE Volatility Index (VIX). The results identify a higher negative co-relationship between the VIX and GSIB returns during the COVID-19 period compared with the Global Financial Crisis (GFC), with one-day lagged changes in the VIX negatively Granger-causing bank returns. The asymmetric impact of changes in implied volatility is examined by quantile regressions, with the findings showing that in the lower quartile–where extreme negative bank returns are present–jumps in the VIX are highly significant. This effect is more pronounced during COVID-19 than during the GFC. Additional robustness analysis shows that these findings are consistent during the periods of the Swine Flu and Zika virus epidemics. [ABSTRACT FROM AUTHOR]

Air transport has been identified as one of the primary means whereby COVID-19 spread throughout Europe during the early stages of the pandemic. In this paper we analyse two categories of methods – dynamic network markers (DNMs) and network analysis-based methods – as potential early warning signals for detecting and anticipating COVID-19 outbreaks in Europe on the basis of accuracy regarding the daily confirmed cases. The analysis was carried out from 15 February 2020, around two weeks before the first COVID-19 cases appeared in Europe, and 1 May 2020, approximately two weeks after all the air traffic in Europe had been shut down. Daily European COVID-19 information sourced from the World Health Organization was used, whereas air traffic data from Flightradar24 has been incorporated into the analyses by means of four alternative adjacency matrices. Some DNMs have been discarded since they output multiple time series, which makes it very difficult to interpret their results. The only DNM outputting a single time series does not emulate the COVID-19 trend: it does not detect all the main peaks, which means that peak heights do not match up with the increase in the number of infected people. However, many combinations of network analysis based methods and adjacency matrices output good results (with high accuracy and 20-day advance forecasts), with only minor differences from one to another. The number of edges and the network density methods are slightly better when dynamic flight frequency information is used. [ABSTRACT FROM AUTHOR]

Several recent studies suggest that the home advantage, that is, the benefit competitors accrue from performing in familiar surroundings, was—at least temporarily—reduced in games played without spectators due to the COVID-19 Pandemic. These games played without fans during the Pandemic have been dubbed 'ghost games'. However, the majority of the research to date focus on soccer and no contributions have been provided for indoor sports, where the effect of the support of the fans might have a stronger impact than in outdoor arenas. In this paper, we try to fill this gap by investigating the effect of ghost games in basketball with a special focus on the possible reduction of the home advantage due to the absence of spectators inside the arena. In particular, we test (i) for the reduction of the home advantage in basketball, (ii) whether such reduction tends to disappear over time, (iii) if the bookmakers promptly adapt to such structural change or whether mispricing was created on the betting market. The results from a large data set covering all seasons since 2004 for the ten most popular and followed basketball leagues in Europe show, on the one hand, an overall significant reduction of the home advantage of around 5% and no evidence that suggests that this effect has been reduced at as teams became more accustomed to playing without fans; on the other hand, bookmakers appear to have anticipated such effect and priced home win in basketball matches accordingly, thus avoiding creating mispricing on betting markets.

Background Early reports on the pandemic nature of coronavirus disease 2019 (COVID-19) directed the nephrology community to develop infection prevention and control (IPC) guidance. We aimed to make an inventory of strategies that dialysis centres followed to prevent infection with COVID-19 in the first pandemic wave. Methods We analyzed IPC measures taken by hemodialysis centres treating patients presenting with COVID-19 between 1 March 2020 and 31 July 2020 and that completed the European Renal Association COVID-19 Database centre questionnaire. Additionally, we made an inventory of guidelines published in European countries to prevent spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in dialysis centres. Results Data from 73 dialysis units located in and bordering Europe were analyzed. All participating centres implemented IPC measures to mitigate the impact of SARS-CoV-2 during the first pandemic wave. Measures mentioned most often included triage with questions before entering the dialysis ward, measuring body temperature, hand disinfection, masking for all patients and staff, and personal protective equipment for staff members. These measures were also recommended in most of the 14 guidelines that were identified in the inventory of national guidelines and were also scored as being among the most important measures by the authors of this paper. Heterogeneity existed between centres and national guidelines regarding the minimal distance between dialysis chairs and recommendations regarding isolation and cohorting. Conclusions Although variation existed, measures to prevent transmission of SARS-CoV-2 were relatively similar across centres and national guidelines. Further research is needed to assess causal relationships between measures taken and spread of SARS-CoV-2. [ABSTRACT FROM AUTHOR]

The subject of this research is guest experience in hotels. We started this research with the initial hypothesis that individual aspects of hotel products and services influence overall guest experience. The aim was to show which aspects of hotel products and services have the strongest impact on guest satisfaction. Another aim was to find out whether there is a difference between the periods before and during the Covid-19 pandemic where factors influencing guest satisfaction are concerned. Guest satisfaction is one of the main goals of a hotel and its business philosophy. Numerous papers investigating the attributes determining guest satisfaction are referred to in the literature review. Data for this research was collected by analysing the 590 surveys sent to guests following their stay in hotels during 2019 and 2021. Via these surveys, guests rated their overall experience during their stay, as well as different individual categories related to the stay. According to the results of the study, guestroom experience has the most significant impact on overall guest experience. Therefore, hotel management should pay attention to room attributes that could be a competitive advantage in differentiation strategy. Cleanliness should be considered one of the most important room attributes, as it now has a stronger impact on overall guest satisfaction than was the case before the outbreak of Covid-19.

COVID-19 represents the greatest health crisis in recent human history. To date, it is still difficult to estimate its impact on mortality. This paper investigates the excess crude mortality in 27 European countries. The differences between the values observed in 2020 and 2021 with those predicted by a joinpoint regression model were evaluated. A multi-regression analysis was implemented to assess the relationship between health variables and excess mortality. Europe experienced a marked and surprising (S-value > 52) increase in crude mortality during 2020 (Δ% = +10.0%, 95% CI: [2.5; 18.7]) and 2021 (Δ% = +12.1%, 95% CI: [4.3; 21.2]). The difference between average excesses of Eastern and Western countries was not surprising (S < 2) and had little relevance (ΔE-W = −2.4, 95% CI: [−2; 7]) during 2020 but was more pronounced (S = 15, ΔE-W = +17.2, 95% CI: [11.0; 23.5]) during 2021. Excess crude mortality increased in 2021 (Δ% = +65%, 95% CI: [12.6; 118], S = 5.9). Evidence has been found for a surprising and marked negative linear relationship between COVID-19 vaccinations and excess mortality ("2021 excess mortality = A + BX4", with "A = 58 ± 7, S = 28" and "B = −0.65 ± 0.10, S = 22, Radj2 = 0.65, 95% CI: [0.38; 0.82]). In light of the current literature, these findings provide solid evidence of the substantial role of COVID-19 in the unexpected and marked excess mortality recorded in Europe. COVID-19 vaccinations have appeared to be one of the main determinants for reducing mortality. Future research should explore these aspects in more detail. [ABSTRACT FROM AUTHOR]

Using a five-year data set including the crowd-less games in the 2020 English, Spanish, Italian, and German first division football leagues and multivariate regression analysis, this paper estimated how fans influence home field advantage. Consistent with previous studies, the estimates showed that in games with crowds, referees gave fewer fouls, yellow cards, and red cards but more penalty kicks to the home team than to the away team. Removing the fans from the stadium eliminated these home advantages coming through referee decisions. Removing fans reduced yellow and red cards given to away teams but did not change cards given to home teams. There was not a similar asymmetry for fouls and penalty kicks. These results suggest that crowds influenced referee judgments about how severe an infraction was more than they influenced decisions about whether a foul occurred. The addition of VAR had little impact on referee decisions and no effect on the home advantage in goal differential. Despite the home bias in referee decisions when crowds were in the stadium, fouls, cards, and penalty kicks played a relatively small role in determining home advantage in game outcomes and most of the home advantage remained after fans were removed.

Real estate represents one of the most profitable and of interest areas of investment. In 2019, the year before the pandemic, real estate represented 3.1% of Europe's GDP, and investment in new constructions or in the renovation of old ones accounted for more than 10% of all investment products in the European economy. This paper analyses the evolution of the real estate industry in the post-pandemic period, the trend being a favourable one, of growth. Real estate constitutes the basis for the proper functioning and development of the other sectors of the economy, therefore it is important to analyse the reaction of the industry in relation to an economic crisis, such as the one caused by the Covid-19 pandemic. The crisis has been the subject of debate for the past two years, as it has caused unprecedented changes in Europe's economy and, of course, in residential markets. Currently, the geopolitical situation in Europe, represented by the conflict in Ukraine and the refugee crisis, has the effect of increasing energy costs, the price of building materials and labour costs. In the given context, we reflected how the real estate market in Europe evolved in the pre- and post-pandemic period, following a series of essential indicators in the field: the evolution of constructions, real property prices, mortgage rates, rents and purchasing power of investors.

The outbreak of the COVID-19 global pandemic has strongly affected different issues of everyday life. The pandemic has changed consumer attitudes and behavior. Consequently, during COVID-19, businesses had to decide how to organize the advertising campaigns and what content should be addressed to consumers. Considering the limited number of articles concerning these issues, it seems important to evaluate the impact of the global health crisis on advertising messages in different countries. The main objective of this paper is to assess TV commercial campaigns implemented during the COVID-19 pandemic, including the specific epidemic situation in the selected countries. The research methodology was based on the observation, a qualitative method of collecting data obtained through monitoring the content of TV commercials aired during the afternoon, before or after the main news service. The research was conducted in May 2020 and in May 2021 in five selected European countries affected to varying degrees by the coronavirus pandemic. The research results allowed evaluation of the advertising messages in terms of their content and values exposed. The findings indicate that the number of COVID-related TV commercials is not correlated with the number of patients and deaths from COVID-19. The themes appearing the most often in the TV commercials in the studied period were the #StayAtHome idea, family and friends, the aspect of safety during the crisis, and brands' special offers. The tone of the advertisements was usually uplifting and hopeful, trying to cheer the stressed societies. From a theoretical perspective, the research results show the advertising strategy issues in specific conditions in different European countries. These findings concerning TV commercial strategy during a pandemic crisis could provide references for other countries, especially in Europe. The research results could be useful for marketing managers in developing strategies concerning the successful planning of TV commercials in crisis periods in European countries.

Coronavirus disease 2019 (COVID-19) has resulted in approximately 5 million deaths around the world with unprecedented consequences in people's daily routines and in the global economy. Despite vast increases in time and money spent on COVID-19-related research, there is still limited information about the factors at the country level that affected COVID-19 transmission and fatality in EU. The paper focuses on the identification of these risk factors using a machine learning (ML) predictive pipeline and an associated explainability analysis. To achieve this, a hybrid dataset was created employing publicly available sources comprising heterogeneous parameters from the majority of EU countries, e.g., mobility measures, policy responses, vaccinations, and demographics/generic country-level parameters. Data pre-processing and data exploration techniques were initially applied to normalize the available data and decrease the feature dimensionality of the data problem considered. Then, a linear ε-Support Vector Machine (ε-SVM) model was employed to implement the regression task of predicting the number of deaths for each one of the three first pandemic waves (with mean square error of 0.027 for wave 1 and less than 0.02 for waves 2 and 3). Post hoc explainability analysis was finally applied to uncover the rationale behind the decision-making mechanisms of the ML pipeline and thus enhance our understanding with respect to the contribution of the selected country-level parameters to the prediction of COVID-19 deaths in EU.

The paper provides insights into the mental health consequences of the coronavirus disease 2019 (COVID-19) pandemic from the Central, Eastern, Nordic, Southern, and Western subregions of Europe, represented by five member countries of the European Society for Traumatic Stress Studies (ESTSS). On the basis of the existing national research and experiences in these countries, we propose five lessons learned. (1) There is no evidence of a mental health pandemic so far in the countries in focus. No increase in severe mental disorders but some increase in the symptoms of common mental health disorders are observable. More high-quality longitudinal studies are needed to understand the mental health burden of the pandemic. (2) The pandemic affects countries (including the mental health situation) differently, depending on the level of the exposure, management policies, pre-pandemic structural characteristics, and healthcare resources. (3) The pandemic affects people differently: the exposure severity to pandemic-related stressors differs between individuals, as well as individual resources to cope with these stressors. There are winners and losers as well as identifiable at-risk groups that need particular attention. (4) Besides the negative consequences, the pandemic has had a positive impact. The rapidly applied innovations within the system of healthcare responses provide a window of opportunity for positive changes in mental healthcare policies, strategies, and practices. The increased focus on mental health during the pandemic may contribute to the prioritization of mental health issues at policy-making and organizational levels and may reduce stigma. (5) A stress- and trauma-informed response to COVID-19 is required. The European community of psychotraumatologists under the leadership of ESTSS plays an important role in promoting stress- and trauma-informed healthcare and policies of pandemic management. Based on the lessons learned, we propose a stepped-care public mental health model for the prevention of adverse mental health outcomes during pandemics. Population mental health is affected differently in the COVID-19 pandemic: there are winners and losers, as well as identifiable at-risk groups that need particular attention. A stress- and trauma-informed public mental health stepped-care model can address pandemic-related mental health burden in a systematic way. [ABSTRACT FROM AUTHOR]

This paper investigates the role of large outbreaks on the persistence of Covid-19 over time. Using data from 650 European regions in 14 countries, I first show that winter school holidays in late February/early March 2020 (weeks 8, 9 and 10) led to large regional outbreaks of Covid-19 in the spring with the spread being 60% and up-to over 90% higher compared to regions with earlier school holidays. While the impact of these initial large outbreaks fades away over the summer months, it systematically reappears from the fall as regions with school holidays in weeks 8, 9 and 10 had 30–70% higher spread. This suggests that following a large outbreak, there is a strong element of underlying (latent) regional persistence of Covid-19. The strong degree of persistence highlights the long-term benefits of effective (initial) containment policies, as once a large outbreak has occurred, Covid-19 persists. This result emphasizes the need for vaccinations against Covid-19 in regions that have recently experienced large outbreaks but are well below herd-immunity, to avoid a new surge of cases.

The Covid-19 pandemic has brought great financial problems to the whole world. The football industry also felt the negative effects. A two-month break from not playing football matches affected all football factors. The clubs lost income from various sources, among which they were most financially affected by the lack of fees for TV rights and the loss of earnings from the game itself. The Covid-19 pandemic caused problems even after the return of football competitions, among other things due to the ban on spectators coming to the stadiums. There was no income from nonfootball sources, such as concerts and other events held at football stadiums. Due to the firm connection between the media, the economy and football, the aim of this paper is to present, from an economic and media point of view, the situation in which the football industry in Europe finds itself under the influence of the Covid-19 pandemic.

Acromegaly embraces typical complications of a pituitary tumor as well as GH (growth hormone) and IGF1 (insulin-like growth factor) excess-related cardio-metabolic and oncologic conditions; and associated medical, surgical treatment or even radiotherapy issues. We point out a few particular aspects concerning acromegaly issues amid COVID-19 pandemic. The review includes only full length, English published papers. One of the most important complications of long standing, untreated or un-responsive to therapy acromegaly is related to respiratory and otorhinolaryngology issues like sleep apnea; this becomes an important aspect causing pulmonary complications in patients with active coronavirus infection. In subjects who are not going through a COVID-19 infection, but they had a prior diagnostic of acromegaly, two main aspects of medical and surgical practice were noted: a massive reduction of surgical volume during the first year of pandemic, mostly during peak months of high infection rate in general population and the introduction of tele (digital) health care systems, of different protocols and various platforms mostly depending of medical center, rather than country or even continent related protocols. Associated central adrenal insufficiency requires a particular attention if COVID-19 positive. The data directly targeting the endocrinologists amid pandemic are very limited. ACROCOVID is a 2021 study that was internationally conducted based on a questionnaire that was applied to 84 endocrinologists (67% of them in Europe); 33% of acromegalic individuals had a delay on procedure because of insufficient COVID-19 assays and 54% of them due to inefficient provision for neurosurgery. Secondary diabetes mellitus (with a potential worsening in some patients due to pasireotide LAR) is at high risk for COVID-19 infection; the level of glycated hemoglobin A1c seems a good predictor at onset of infectious disease. Acromegaly might associate osteoporosis; coronavirus infection aggravates bone loss due to oxidative stress, inflammatory status, cytokine release, immobilization, glucocorticoid use. Acromegaly field concerning pandemic changes represents a complex, still ongoing matter involving both patients and multidisciplinary practitioners. [ABSTRACT FROM AUTHOR]

The current pandemic is sustained in dichotomies and distancing, as most of us awkwardly have recently experienced. Moreover, COVID-19 has definitely put the spotlight on social inequalities that are underpinning our society and it has highlighted the escalation of the state surveillance capability and new forms of oppression too. The discrimination ingrained in our societies, built on a historically defined regime of racialized oppression and structural disadvantage of racialized citizens and migrants, was produced well before the coronavirus, but it is now casting a different shade, reinforcing forms of exclusions, highlighting the pandemic as a political issue. Hence, this paper addresses a range of political perspectives of the lived experiences in and through social space with examples of narratives in language which capture the everyday political experiences of the pandemic within Europe. The kind of language used and its profound effect on the growing discourse regarding COVID-19 is the main focus in this paper. I here explore the intertwining of language and politics during the pandemic and bring out the countervailing narratives that seem to be in constant tension. I then ask where this takes us, not only in terms of scholarship and expansion of knowledge, but also with a pragmatic edge to it, trying to figure out how is it possible for us to achieve some sort of cognitive shift in our approach in order to learn from this challenge and from this new perspective. Methodologically, as well as looking at existing data, references to attitudes in general are made. A theoretical discussion on migration and language, and the kind of intersection between them, is offered, from the point of view of critical theory, before pointing to the metaphors used, the implications they allow, and how all these fit together, in the form of a concluding discussion. Metaphor or not, the power of language in its ramifications of articulations about the pandemic and the idea of distance underlines COVID-19 as a deeply political issue. [ABSTRACT FROM AUTHOR]

This paper examines the risk transmissions across the green economy indices of three major regions which include US, Europe and Asia. The econometric analyses are conducted using DCC-GARCH and TVP-VAR connectedness approach to evaluate potential spillover effects within the context of oil and gold. Results indicate that green economy indices of US-Europe exhibit the greatest time-varying correlations among the three pairs during much of 2010–2022 consistent with that of the general equity market. However, co-movements during the COVID-19 pandemic period seem to display a change in pattern for green economy indices. The strength of the co-movements between the US and Europe displayed a declining trend, while that between US and Asia was strengthened, suggesting greater interdependence between these two markets. TVP-VAR connectedness analysis revealed that US and Europe dominate the transmission of the shocks across the years in the green economy, similar to that of the equity markets. However, during the pandemic a pronounced shift occurred in green economies when considering the risk transmissions within the context of commodities: oil and gold. While Asian green economy index was persistently a receiver of risk transmission from oil unlike the other two regions, since pandemic, oil displayed an asymmetric effect and has become the net transmitter of risk in negative returns of the green economies of US and Europe. This may reflect the diversion in environmental policies of the two regions in the recent past, and point to the dominance of energy sector in the green economy. These findings have substantial implications for the development of green economy policies and from an investment perspective. [ABSTRACT FROM AUTHOR]

There a lot of review papers addressing specific COVID-19 research sectors, then devoted to specialists. This review provides an in-depth summary of the available information about SARS-CoV-2 and the corresponding disease (also known as COVID-19), with a multi-disciplinary approach. After the paper introduction, the first section treats the virological characteristics of SARS-CoV-2, the medical implications of the infection, and the human susceptivity. Great attention is devoted to the factor affecting the infection routes, distinguishing among the possible human-to-human, environmental-to-human, and pollution-to-human transmission mechanisms. The second section is devoted to reporting the impact of SARS-CoV-2 not only on the healthcare systems but also on the economy and society. The third section is devoted to non-pharmaceutical behaviours against COVID-19. In this context, this review section presents an analysis of the European second wave allowing not only to focalize the importance of some restrictions, but also the relevance of social acceptance of some measures. The data reassumed in this work are very useful for interdisciplinary researchers that work in a team to find the basic available information about all the aspects connected with this pandemic (from virus diffusion mechanism to health information, from economic and social impacts to measures to reduce the pandemic spread), with great attention to social acceptance of restriction measures and of vaccines (that currently results to be insufficient to achieve community immunity). Then, this review paper highlights the fundamental role of the trans-multi-disciplinary research that is devoted not only to understand the basics of the pandemic to propose solutions but has also the commitment to find strategies to increase population resilience. For this aim, the authors strongly suggest the establishment of an international health-care trans-multi-disciplinary workforce devoted to investigate, mitigate, and control also future viral events. [Display omitted] • COVID-19 is a highly transmissible disease that has spread all over the globe. • The interdisciplinary research strategy in pandemic has a basic role. • Some concerns due to the reported transmission mechanisms must be better investigated. • The social acceptance of vaccine and restriction measures must be improved. • A health-care multidisciplinary workforce for pandemic study should be established.

The recent COVID-19 pandemic affected various aspects of life. Several studies established the consequences of pandemic lockdown on air quality using satellite remote sensing. However, such studies have limitations, including low spatial resolution or incomplete spatial coverage. Therefore, in this paper, we propose a machine learning-based scheme to solve the pre-mentioned limitations by training an optimized space-time extra trees model for each year of the study period. The results have shown that our trained models reach a prediction accuracy up to 95% when predicting the missing values in the MODIS MCD19A2 Aerosol Optical Depth (AOD) product. The outcome of the mentioned scheme was a geo-harmonized atmospheric dataset for aerosol optical depth at 550 nm with 1 km spatial resolution and full coverage over Europe. As an application, we used the proposed machine learning based prediction approach in AOD levels analysis. We compared the mean AOD levels between the lockdown period from March to June in 2020 and the mean AOD values of the same period for the past 5 years. We found that AOD levels dropped over most European countries in 2020 but increased in several eastern and western countries. The Netherlands had the most significant average decrease in AOD levels (19%), while Spain had the highest average increase (10%). Moreover, we analyzed the relationship between the relative percentage difference of AOD and four meteorological variables. We found a positive correlation between AOD and relative humidity and a negative correlation between AOD and wind speed. The value of the proposed prediction scheme is further emphasized by taking into consideration that the reconstructed dataset can be used for future air quality studies concerning Europe.

The aging of human populations, including those in Europe, is an indisputable fact. The challenge for the future is not simply prolonging human life at any cost or by any means but rather extending self-sufficiency and quality of life. Even in the most advanced societies, the eternal questions remain. Who will take care of the older generations? Will adult children's own circumstances be sufficient to support family members as they age? For a range of complex reasons, including socioeconomic conditions, adult children are often unable or unwilling to assume responsibility for the care of older family members. For this reason, it is imperative that aging adults maintain their independence and self-care for as long as possible. Movement is an important part of self-sufficiency. Moreover, movement has been shown to improve patients' clinical status. At a time when the coronavirus pandemic is disrupting the world, older people are among the most vulnerable. Our paper explores current knowledge and offers insights into the significant benefits of movement for the elderly, including improved immunity. We discuss the biochemical processes of aging and the counteractive effects of exercise and endogenous substances, such as vitamin D. [ABSTRACT FROM AUTHOR]
