Spanish Study to Analyze the Histopathological, Ultrastructural and Microbiological Findings Obtained...
Covid19The aim of this study is prospectively analyzing the histopathological, ultrastructural and microbiological findings from autopsies performed on patients with COVID-19.
Analysing the French COVID-19 Epidemic Using a National SARS-CoV-2 RT-PCR Database
Covid-19SARS-CoV InfectionAnalysing ths spread of COVID-19 epidemics in a timely manner is key to implementing public health control strategies. The investigators propose to analyse a large set of laboratory SARS-CoV-2 RT-PCR data to explore potential links between Ct values and epidemic parameters.
Physical Activity Post COVID-19
Covid19The purpose of this study is to characterize functional status and physical activity of patients with COVID-19 after hospital discharge.
Management of Acute Appendicitis at District General Hospital
Appendicitis AcuteCovid19The Investigators aim to assess; whether the changes in managing patients during COVID has reduced the negative appendicectomy rate? compare the difference in outcomes of conservatively and surgically managed Acute Appendicitis? Whether there uniformity in prescribing postoperative antibiotics with resultant outcomes? Whether the incidence of complicated appendicitis has increased?
Neurocognitive Functions of Recovered COVID-19 Patients
CognitionCovid-19This study is carried on in Wuchang Hospital in Wuhan, China. The investigators plan to recruit 80 patients with COVID-19 and 80 matched healthy control. Using the design of case-control study, the study aims to assess the neurocognitive functions such as executive function and attentional bias in recovered patients with COVID-19 under normal and stress conditions, and to analyze the influencing factors of neurocognitive functions, such as mental health conditions, inflammation indicators and cardiopulmonary function.
Differential Expression of Cytokines, Transcriptome and miRNA in Coronavirus Disease 2019 (COVID-19)...
Corona Virus InfectionThe aim of this effort is to study host-pathogen interaction in Egyptian patients infected with COVID-19. The investigators will perform genome-wide miRNA and transcriptome screens in the infected patients along with healthy ones for comparison. All types of cytokines play pivotal roles in immunity, including the responses to different viral infections. Therefore, The investigators will study the cytokines profile in response to that infection. By comparing miRNA and transcriptome screens along with cytokines profiles, an important molecule might be identified that could play role in the inhibition of the COVID-19 outbreak. In addition, this information will help us gaining awareness of the immune process and knowing about the genes involved in the immune response against COVID-19 with an emphasis on the expression of cytokines.

DysphagiaDysphonia8 moreThis study examines the presence, severity and natural history of dysphagia and dysphonia in the post-extubation and severely unwell COVID-19 patient.
Pulmonary Embolism and COVID-19
Covid-19Pulmonary EmbolismThe charts of patients who developed pulmonary embolism in the course of COVID-19 will be evaluated, retrospectively. Clinical features and laboratory data will be analyzed.
The Relationship Between Covid-19 Infection in Pediatric Patients and Secondary Lymphoid Organs...
Covid19Immune Deficiency4 moreWe aimed to find out whether the tonsils and nasal tissues of pediatric patients are the main factors that protects the children's immune system against COVID-19 infection.
