This is a first-in-human, Phase I/II, randomized, placebo-controlled, observer-blinded,age-escalating study to assess the safety, reactogenicity and immunogenicity of a SKSARS-CoV-2 recombinant protein nanoparticle vaccine (GBP510) adjuvanted with or withoutAS03 in healthy younger and older adults.

In order to prevent reinfection, it is needed to detect the cellular-mediated immuneresponse to the Sars-CoV-2 infection. The first goal of this study will be to detect thecellular-mediated immune response in patients affected by COVID-19 (with or withoutvaccination) and healthy subjects who undergone vaccination program. The second goal ofthis study will be to identify the genetic and epigenetic biomarkers that influenceindividual immunological response and clinical evolution to the severe manifestations ofthe COVID-19.

Determination of both the degree and duration of the immunity provided after receivingthe BNT162b2 vaccine against SARS-Cov-2.

The COVID-19 can cause important sequels in the respiratory system by bilateral pneumoniaand frequently presents loss of strength, dyspnea, polyneuropathies and multi-organicaffectation. Long COVID-19 has been defined as the condition occurring in individualswith a history of probable or confirmed SARS-CoV-2 infection, with related symptomslasting at least 2 months and not explainable by an alternative diagnosis. The practiceof digital physiotherapy presents itself as a promising complementary treatment method tostandard physiotherapy, playing a key role in the recovery of function in subjects whohave passed the disease and who maintain some symptomatology over time. The aims of thisresearch are to explore the effect of a digital physiotherapy intervention on functionalrecovery in patients diagnosed with Long COVID-19 and to identify the level of adherenceto the treatment carried out. Physiotherapy interventions acquires a fundamental role inthe recovery of the functions and the quality of life. As secondary objectives, the aimis to identify the satisfaction and perception of patients with the intervention and thepresence of barriers to its implementation (throught a qualitative research), as well asto evaluate the cost-effectiveness from the perspective of the health system. Aquasi-experimental pre-post study assessed initially and at the end of the 4-weekintervention the functional capacity (1-min STS and SPPB) and the adherence (software).The hypothesis of this research is that the implementation of a TR program presentspositive results. If hypothesis is confirmed, that would be an opportunity to define newpolicies and interventions to address this disease and its consequences.

Strengthening outpatient low respiratory tract infection surveillance to document theburden of Respiratory Syncytial Virus (RSV)

The proposed study will investigate respiratory aerosols in SARS-CoV-2 (Severe AcuteRespiratory Syndrome Corona Virus 2) positive and negative children and adults with theResp-Aer-Meter (Palas GmbH). For this purpose, first, the measurement of respiratoryaerosols (particle sizes and concentration) with the Resp-Aer-Meter will be established.Thereafter, a comparison between polymerase chain reaction (PCR) SARS-CoV-2 positive andnegative participants (children and adults) will be conducted. In addition to themeasurement of aerosols, the clinical symptoms, lung function (FEV1) and laboratoryinflammatory markers will be analyzed.

Multicenter retrospective and prospective observational study based on the collection ofsequential anonymized data from principal Italian ITP centers, to describe the clinicalcourse of ITP patients becoming infected by SARS-CoV-2 and of COVID-19 patientsdeveloping de novo ITP.

SUMMARY Rationale: Allied health professionals (i.e., dietitians, exercise therapists,physical therapists, occupational therapists and speech and language therapists) mightplay an important role in the recovery of patients with COVID-19 who experiencelimitations in daily physical functioning and participation. However, the evidence basefor allied healthcare in patients with COVID-19 has yet to be established. To facilitatecare for people recovering from COVID-19 and to establish this evidence base, the Dutchministry has created a temporary regulation for primary care allied healthcarespecifically for patients with COVID-19.Objective: This study is setup alongside the temporary regulation and aims to evaluatethe longitudinal recovery trajectories and related costs of patients who visited aprimary care allied healthcare professional for the management of severe symptoms andactivity limitations and/or participation restrictions related to COVID-19.Study design: Prospective cohort study. Study population: 1,315 adult patients recoveringfrom COVID-19 with severe symptoms and activity limitations and/or participationrestrictions, and who are referred to a primary care allied health professional by ageneral practitioner or medical specialist within four months of the start of the diseasewill be eligible for this study.Intervention (if applicable): Although the nature of this study is non-experimental, theallied healthcare intervention can be considered experimental due to the novelty of thedisease.Main study parameters/endpoints: The primary outcome domain of this study isparticipation measured with the Utrechtse Schaal voor Revalidatie - Participatie(USER-P). The primary endpoint is set at 6 months. A 5 point difference will beconsidered clinically relevant for patients with COVID-19.Nature and extent of the burden and risks associated with participation, benefit andgroup relatedness: There are no specific risks involved with participation in this study,as it entails the completion of questionnaires over the timeframe of one year (at thestart of the treatment, the end of the treatment, 3 months, 6 months, 9 months and 12months). The load of the survey will be highest at months 3, 6 and 12 with a total of 74survey items. Input from patient representatives suggested that this number of items wasfeasible, especially because participants are allowed to complete the survey over anumber of days. Finally, none of the items in the survey are considered emotionallydistressing. The prescribed interventions are conform the recommendations of the bestavailable evidence and are in line with usual allied healthcare interventions. Therefore,risks are likely to be negligible conform usual allied healthcare.

Investigating the role of 13cis retinoic acid in the treatment of COVID-19 andenhancement of Its spike protein based vaccine efficacy and safety.

This study investigates the possible adverse effects and effectiveness of convalescentplasma for patients infected with SARS-CoV-2. Following provision of informed consent,patients will be randomized into three groups: High-titre convalescent plasma, low-titreconvalescent plasma or placebo. Primary outcomes of the study will cover safety andeither intubation or initiation of systemic corticosteroids. Safety information collectedwill include serious adverse events judged to be related to administration ofconvalescent plasma. Microbiological and other laboratory parameters will be followed up.
