Impact of COVID-19 on vacation recreational walking: Evidence from an urban coastal destination

This study examined the impact of COVID-19 on recreational walking while on vacation, a relevant activity among tourists especially in urban destinations. We surveyed visitors to Costa Daurada, an urban coastal destination in Catalonia in August 2020. Only 5% of participants reported lower recreational walking levels compared to normal circumstances;75% reported similar levels;and 20% reported higher levels. Higher recreational walking levels were associated with visiting local amenities or strolling and with a higher level of perceived safety from COVID-19 when walking. Higher perceived overcrowding was associated with less recreational walking. The pandemic may have altered recreational behavior while on vacation in urban settings especially by increasing outdoor activities such as recreational walking. If persistent, such behavioral changes could have relevant implications for both the tourism and recreation sectors and for local policymakers who aim to promote walkability while managing tourist pedestrian flows.

PROTECTION OF PERSONAL DATA AND RIGHT TO PRIVACY IN THE CONTEXT OF PANDEMICS: AN ANALYSIS OF CONTACT TRACING APPLICATIONS CONSIDERING THE PROPORTIONALITY

Several countries are taking exceptional measures to control the high spreading capacity of SARS-CoV-2 virus. In order to ensure efficiency in monitoring compliance with these determinations, countries began to use information technology, including the development of contact tracing applications. However, the use of this technology entails State intervention in the right to privacy, as it implies the processing of personal data, so that its constitutionality is questioned in the context of the Brazilian legal system. In this context, this work aims to identify the legal and constitutional limits in the use of contact tracing applications in a pandemic context by the Brazilian State, taking into consideration the right to privacy and the principle of proportionality. This research applied the deductive method and was based on an exploratory and interdisciplinary analysis, making use of both legal-constitutional dogmatics and technical knowledge of information technology. Thus, it is possible to conclude that contact tracing applications must be built following a decentralized architecture, using a proximity-based approach and secure data transmission and information encryption techniques to facilitate data anonymization. © 2022 Fundacao Getulio Vargas, Escola de Direito de Sao Paulo.

Conclusion: Agri-Food Deepening, Sustainable Development Planning, and Policy Platonicity

The SARS-CoV-2 pandemic (COVID-19) drove to the forefront the criticality of agri-food and public health systems in reshaping sustainable development goals. Invariably, agricultural deepening and sustainable development are mutually reinforcing, thereby generating interactive linkages between agriculture and non-agriculture sectors. Improved agricultural competitiveness is essential for economic growth in the sense that agriculture is a large sector, and growth in that sector imposes a high weight on aggregate growth, justifying public investment in agriculture. This concluding chapter wraps up the policy recommendations articulated in this book within the context of areas of future policy research agenda. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

The Introduction: Pandemic Preparedness and A-Platonic Policies for Transforming Africa's Agri-food Systems

Most post-independence African countries have not succeeded in achieving rapid and sustainable economic development over the past five decades. In view of this, it is reasonable to suspect that poor agricultural performance may be a significant contributory factor to the unsatisfactory performance in the region. One of the challenges facing Africa is how to deepen agriculture more systemically towards realizing sustainable development than it has done over the last five decades. How can this be achieved? It is within this context that this introductory chapter seeks to emphasize the need for a-platonifying Africa's agricultural deepening and development planning policies and programmes. In addition, this article discusses the platonic nature of Africa's development and recommends some SARS-CoV-2 pandemic responsive strategies within the concept of platonic policies. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

[Innovative SARS-CoV-2 crisis management in the public health sector: Corona dashboard and wastewater surveillance using the example of Berchtesgadener Land, Germany]. / Innovatives SARS-CoV-2-Krisenmanagement im öffentlichen Gesundheitswesen: Corona-Dashboard und Abwasserfrühwarnsystem am Beispiel Berchtesgadener Land.

BACKGROUND: The rise of an infectious disease crisis such as the SARS-CoV­2 pandemic posed significant challenges for the administrative structures of the public health service, which resulted in varying levels of efficiency in outbreak management as a function of staffing and digital resources. This substantially impeded the integration of innovative pandemic outbreak management tools. Innovative crisis management, such as cluster tracking, risk group testing, georeferencing, or the integration of wastewater surveillance recommended by the EU Commission, was made significantly more difficult. AIM: In this case study in Berchtesgadener Land, we present the integration of an area-wide georeferenced wastewater surveillance system that captured 95% of the entire population since November 2020. METHODOLOGY: Sampling occurred twice a week at nine municipal wastewater treatment plants and directly from the main sewer at three locations. Samples were pre-treated by centrifugation and subsequently analyzed by digital droplet polymerase chain reaction (PCR) targeting four specific genes of SARS-CoV­2. RESULTS: The integration of an area-wide georeferenced wastewater surveillance system was successful. Wastewater occurrences are plotted for each municipality against cumulative infections over seven days per 100,000 inhabitants. Changes in the infection pattern in individual communities are noticeable ten days ahead of the official case numbers with a sensitivity of approximately 20 in 100,000 inhabitants. DISCUSSION: The integration of this innovative approach to provide a comprehensive overview of the situation by employing a digital dashboard and the use of an early warning system via quantitative wastewater surveillance resulted in very efficient, proactive management, which might serve as a blueprint for other municipalities in Germany.

Impact of the SARS-CoV-2 (COVID19) pandemic on the morbidity and mortality of high risk patients undergoing surgery: a non-inferiority retrospective observational study.

BACKGROUND: During the COVID-19 crisis it was necessary to generate a specific care network and reconvert operating rooms to attend emergency and high-acuity patients undergoing complex surgery. The aim of this study is to classify postoperative complications and mortality and to assess the impact that the COVID-19 pandemic may have had on the results. METHODS: this is a non-inferiority retrospective observational study. Two different groups of surgical patients were created: Pre-pandemic COVID and Pandemic COVID. Severity of illness was rated according to the Diagnosis-related Groups (DRG) score. Comparisons were made between groups and between DRG severity score-matched samples. Non-inferiority was set at up to 10 % difference for grade III to V complications according to the Clavien-Dindo classification, and up to 2 % difference in mortality. RESULTS: A total of 1649 patients in the PreCOVID group and 763 patients in the COVID group were analysed; 371 patients were matched for DRG severity score 3-4 (236 preCOVID and 135 COVID). No differences were found in relation to re-operation (22.5 % vs. 21.5 %) or late admission to critical care unit (5.1 % vs. 4.5 %). Clavien grade III to V complications occurred in 107 patients (45.3 %) in the PreCOVID group and in 56 patients (41.5 %) in the COVID group, and mortality was 12.7 % and 12.6 %, respectively. During the pandemic, 3 % of patients tested positive for Covid-19 on PCR: 12 patients undergoing elective surgery and 11 emergency surgery; there were 5 deaths, 3 of which were due to respiratory failure following Covid-19-induced pneumonia. CONCLUSIONS: Although this study has some limitations, it has shown the non-inferiority of surgical outcomes during the COVID pandemic, and indicates that resuming elective surgery is safe.

Analysis of Covid-19 Data for Eight European Countries and the United Kingdom Using a Simplified SIR Model.

Understanding the characteristics of the SARS-Cov-2/Covid-19 pandemic is central to developing control strategies. Here we show how a simple Susceptible-Infective-Recovered (SIR) model applied to data for eight European countries and the United Kingdom (UK) can be used to forecast the descending limb (post-peak) of confirmed cases and deaths as a function of time, and predict the duration of the pandemic once it has peaked, by estimating and fixing parameters using only characteristics of the ascending limb and the magnitude of the first peak. As with all epidemiological analyses, unanticipated behavioral changes will result in deviations between projection and observation. This is abundantly clear for the current pandemic. Nonetheless, accurate short-term projections are possible, and the methodology we present is a useful addition to the epidemiologist's armamentarium. Since our predictions assume that control measures such as lockdown, social distancing, use of masks etc. remain the same post-peak as before peak, deviations from our predictions are a measure of the extent to which loosening of control measures have impacted case-loads and deaths since the first peak and initial decline in daily cases and deaths. The predicted and actual case fatality ratio, or number of deaths per million population from the start of the pandemic to when daily deaths number less than five for the first time, was lowest in Norway (pred: 44 ± 5 deaths/million; actual: 36 deaths/million) and highest for the United Kingdom (pred: 578 +/- 65 deaths/million; actual 621 deaths/million). The inferred pandemic characteristics separated into two distinct groups: those that are largely invariant across countries, and those that are highly variable. Among the former is the infective period, T L ( T L ¯ = 16.3 ± 2.7  days ) ; the average time between contacts, T R ( T R ¯ = 3.8 ± 0.5 ) days and the average number of contacts while infective, R ( R ¯ = 4.4 ± 0.5 ) . In contrast, there is a highly variable time lag T D between the peak in the daily number of confirmed cases and the peak in the daily number of deaths, ranging from a low of T D = 2,4 days for Denmark and Italy respectively, to highs of T D = 12, 15 for Germany and Norway respectively. The mortality fraction, or ratio of deaths to confirmed cases, was also highly variable, ranging from low values 3%, 5% and 5% for Norway, Denmark and Germany respectively, to high values of 18%, 20% and 21% for Sweden, France, and the UK respectively. The probability of mortality rather than recovery was a significant correlate of the duration of the pandemic, defined as the time from 12/31/2019 to when the number of daily deaths fell below 5. Finally, we observed a small but detectable effect of average temperature on the probability α of infection per contact, with higher temperatures associated with lower infectivity. Policy implications of our findings are also briefly discussed.

Don't forget ototoxicity during the SARS-CoV-2 (Covid-19) pandemic!

Aim of this communication is to remind clinical professionals to be aware of ototoxic side effects of several specific drugs proposed for the treatment of the new virus SARS-CoV-2 (Covid-19). In particular, chloroquine and hydroxychloroquine, azithromycin, as well as antiviral drugs such as remdesivir, favipiravir and lopinavir can all present potential ototoxic side effects. The data in the literature do not offer specific information on their potential synergetic effects nor on their interactions.

Novel coronavirus disease pandemic and ophthalmologist's perspectives.

Ophthalmologists are among those healers facing a higher risk of acquiring novel coronavirus disease 2019, called COVID-19, during their professional duties since they have close physical contact with their patients. Some patients with COVID-19 may present with or may develop conjunctivitis during the course of the illness. The ocular secretions and tears have been identified to have positive results to COVID-19 tests and as such could be a source of spread. This review aims at providing the useful guidelines to ophthalmic professionals for their own safety, and safety of their patients based on the available current literature, and also based on personal experience and observations. Literature search was made on PubMed for COVID-19 in relation to ophthalmology in the limited period of the last quarter of 2019 and first quarter of 2020. Research also included access to current guidelines published by various ophthalmic societies. Accordingly, present and future ophthalmic practice patterns need to be modified.
