TraAct-DD - Track and Act with Data Donation #getout #stayout

Luxembourg is entering a gradual deconfinement phase. For this to be successful, it is critical that the country protect vulnerable people and build the trust of the population in going back to work, to school safely. It is also vital to identify asymptomatic COVID-positive patients and to wisely direct the (scarce) tests. If Luxembourg can manage this, epidemiological models indicate that a gradual release of the population may stem the pandemic and enable return to normal (#getout, #stayout). The ongoing debate at the government level indicates hesitation between blue-tooth tracing, ma...

Rapid large-scale decontamination of viruses using Engineered Water Nanostructures

Engineered Water Nanostructures (EWNS) are nanometer-sized droplets of ionized or charged water containing reactive oxygen species (ROS) which provide a highly effective, low cost, green, non-toxic of humans solution for rapid decontamination of microbes. Unlike harmful chemicals currently used in disinfectants, charged water has no effect on humans and has been found to be a safer alternative. Additionally, CDC has already added superoxidized (containing EWNS) water among the list of disinfectants found to be effective against viruses. In this project, we propose design, development, ...

Rapid Development and Initial Preclinical Evaluation of an Effective Candidate Vaccine against SARS-CoV-2

The current pandemic caused by SARS-CoV-2 is a threat not only to global health but also to the economy since it is dramatically affecting the socioeconomic layers of societies around the planet. Thus, it will be critically important to advance in the production of an effective vaccine, which will be crucial for building up sufficient population-based immunity to efficiently curb the pandemic. While SARS-CoV-2 can infect everyone at all ages, it is mainly the elderly population that is most at risk of a fatal outcome. Elderly persons are charecterized by a declining immune function, known a...

Pocket Rehab - mHealth-based Rehabilitation Program for patients with cardiovascular disease as p...

Cardiovascular diseases remain the major cause of mortality with an estimated prevalence of 422.7 million cases worldwide at high cost for the public health. Recently, the pathophysiological mechanism of the coronavirus uses the angiotensin-converting enzyme 2 (ACE2) as a functional receptor, increasing the risk of contamination and the mortality rate in this population, aggravating this scenario. According to the epidemiological bulletin of COE-COVID19 of the Ministry of Health of Brazil, among the 1124 deaths recorded until 11 April 2020, in those under the age of 60, 82.5% had illness a...

COVID-19 and chronic diseases: national health care provider survey

COVID-19 is placing unprecedented pressures on healthcare systems. The current declared pandemic has urged healthcare professionals to reorganise profoundly their everyday practice while trying to maintain care for other patients. Since the 'lockdown' situation in Luxembourg, changes in the medical sector include the opening of advanced care centres, promotion of teleconsultations and restrictions on non-urgent health care. Pre-existing chronic diseases such as cancer, cardiovascular and respiratory disease are reported as being major risk factor for severe COVID-19 health outcomes (Jordan ...

COVI-NUTRI-METABOLOMICS

Background: A poor nutrient status due to sub-optimal dietary habits increases risk of viral infections. In particular, individuals with low vitamin D, A and E, as well as zinc plasma levels are less likely to develop immune-responses against influenza vaccines. Vitamin C supplementation improves conditions in individuals with acute respiratory infections in some studies. Dietary fiber is inversely correlated with mortality from respiratory/infectious disease. These nutrients are paramount for optimal immune-response, are implicated in oxidative stress, inflammatory processes, and viral rep...

Impact of hypoxia on COVID-19 infection in lung epithelial cells

The international spread of coronavirus disease 2019 (COVID-19) has recently caused over 120.000 deaths in Europe and 200.000 worldwide. The clinical picture goes from the absence of symptoms to critical conditions requiring admission to resuscitation units. The molecular pathways involved in COVID-19 infection and pathogenesis are still being explored. 'Silent hypoxia' is considered by some physicians as an early indicator of COVID-19 viral infection in patients. A key step in COVID-19 infection is the viral entry into pulmonary alveoli epithelial cells, leading to the disruption of surf...

Covid-19 related LOckdown: Shift in Exposures to neighbourhood environments and changes in Physic...

A lockdown state implies radical changes in our lifestyle, especially physical activity (PA), while PA plays a central role in maintaining an adequate health status, counteracting the negative consequences of numerous diseases. We aim to investigate the impact of lockdown (and quarantine) on PA patterns based on retrospective data. We will analyse the intra-individual changes in PA patterns of participants stratified in two specific subgroups of interest, namely positive cases and their household members as a result of the lockdown/quarantine measures in place, with respect to the partici...
