COVID-19 Clinical Trials and Expanded Access

Newborns and infants receive passive natural immunity through maternal antibodies present in breastmilk to fight infections caused by viruses such as the COVID-19, until they develop active immunity by illness or vaccination. Such immunity will become the main stay for preventing future waves of COVID-19 epidemics. The high COVID-19 mortality among African Americans is ascribed partly to compromised immune status associated with comorbidity. Exclusive breastfeeding (EBF) is the effective low-cost natural strategy for building immunity right from birth. African Americans record the lowest EBF rates and also lack workplace support. This intervention includes a 10-hour course extracted from 90-hour CLC online program, sufficient to prepare physicians to partner with certified lactation consultant (CLC) to provide their patients comprehensive COVID-19 breastfeeding guidelines, training, and support to afford their babies the benefits of breastmilk antibodies, the best line of defense against COVID-19, until availability of safe vaccines. The Breastfeeding Report Card indicates slow improvements in overall breastfeeding rates with persisting disparities. Improving EBF rates can contribute to increased COVID-19 immunity among infants. Preliminary data in Nashville indicates excellent breastfeeding benefit knowledge and intent, but limited training to succeed. Hospital staff encourage breastfeeding but routinely offer formula at birth. Most physicians who provide prenatal care do not actively promote breastfeeding nor routinely offer CLC referral. This single action by physicians can halt routines that compromise successful EBF. The program long-term goal is to prepare obstetricians to actively promote comprehensive breastfeeding among African American mothers. The immediate objective is to develop and evaluate feasibility and effectiveness of an intervention designed to increase COVID-19 breastfeeding guideline adherence and improve EBF skills and rates among African American mothers. The rationale is that mothers who receive physician prenatal encouragement and CLC referral will make confident informed decisions, adopt COVID-19 breastfeeding guidelines, safely meet their EBF goals, and provide their infants with appropriate antibodies. The expected outcome is that patient participants will adhere to COVID-19 breastfeeding guidelines and record 3-month EBF rate 60 percent or greater.

The study aim is to collect and analyze data of potential Volatile Organic Compounds (VOCs) that could be used for discriminating between patients with and without COVID-19 or with high-risk for COVID-19 by DiaNose breath test. up to 300 subjects will be enrolled to the study ( 200 COVID-19 suspected and 100 healthy volunteers in two clinical sites (1 in Israel and 1 in US). DiaNose system is an electronic nose device that can "smell" diseases in the exhaled breath of patients in real time. This approach is non-invasive, simple and save. The DiaNose prototype system consists the following elements: A Soft Tube connected to a Sensors Chamber - The soft tube is made of medical grade silicon. The subject blows air into the tube for a few seconds and the exhaled air is directed through the sensors chamber. This unit is for single use. • Sensors Reading Unit- a multi used unit for sensors signals measurement. The Sensor Reading Unit is connected to a Laptop that is used to activate and save the test measurements.

In this project, we aimed at developing new "Ready-to-Use" inhalable forms of HCQ that can be used directly through nebulization or using dry powder inhalers (DPIs). These inhaled forms would allow a simple and direct delivery of the drug (HCQ) specifically towards the throat and the lung which are the main sites for the COVID-19 viral infection. Hence, the drug can be available at higher concentrations in the throat and lungs as compared with the currently used treatment protocols, while minimizing the drug systemic concentrations and its presence in other body organs, and thus enhancing the drug efficacy with significantly limiting its side effects. Besides, using inhalable forms can be more convenient to patients suffering from gastrointestinal complications from the disease that can limit the absorption of oral forms. Moreover, the proposed inhalable forms are designed in such a way to hide the drug from the immune system (confer stealth characteristics) using FDA-approved excipients to minimize/avoid any immune response towards the drug as was noted towards it in its oral form that's used in the treatment protocol of COVID-19. In addition, the inhaled formulations will be designed to maintain the overall simplicity and scalability of the preparation which is critical during this urgent pandemic situation. The cost of the final formulation is also taken into consideration since the drug is intended for treatment of thousands or probably millions of patients around the world including countries with limited economic capabilities.

The Lille University Hospital developped a research objective common to all the services which took care of patients, "suspected patient", "possible case", "probable case" or "confirmed case" infected with SARS-CoV-2 by constituting a prospective and a retrospective observational cohort which allowed pooling and sharing the resources and data collected. In the next two years the prospective cohort will allow to continue inclusions in a standardized way mainly for the constitution of a negative control group (excluded cases), to collect biological samples which had not been collected in the retrospective cohort so that the pathophysiology of the COVID-19 will be better apprehended as for example the inflammatory response to the viral infection. Finally in case of a second epidemic wave in the Hauts De France, it seems essential to have a defined research protocol which had already received all the necessary authorizations to guarantee cutting-edge (or quality ) research in a center like the Lille University Hospital.The aim objective of this study is to identify predictive factors of mortality to day 28 infection to SARS-CoV-2 for patients under medical care for the COVID-19 in the Lille University Hospital thanks to the constitution of an epidemiological, clinical, biological, immunological, genetic, microbiological, anatomopathologic, radiological, therapeutic database and so record the results of functional exploration exams.

The coronavirus outbreak is a stressful event for the whole population. Confinement measures are protective against the risk of dissemination of the virus, but they can also lead to several psychological symptoms. In children, a study in China has reported about 20% of depressive or anxious troubles in school-age children after a 4-week period of confinement. In France, confinement lasted about 8 weeks. School resumed on May 11th for primary school children and on June 2nd for secondary school children. In this survey, we aim at exploring the psychological status of these children and the impact on their schooling, for better understanding, support and prevention. Through this online questionnaire, we also aim at giving some psycho-education advices. Finally, we could identify some subgroups of children particularly vulnerable, and organise some specific support for them in coming months.

This study is intended to address the association between vitamin D status and seroconversion to SARS-CoV-2 in healthy young adults. The primary aim of the study is to determine the rates of 'silent' seroconversion rates, consistent with asymptomatic transmission of SARS-CoV-2, in a young healthy adult population with a wide spread of vitamin D concentrations. The secondary aims of this study are to explore: 1. Any effect of vitamin D status on symptomatic illness. 2. The background 'point' prevalence and subsequent rate of increase in seropositivity for SARS-CoV-2 in healthy young adults. 3. The individual reductions in seropositivity to SARS-CoV-2 over time, and changes in seropositivity in a defined young adult population over time. 4. Where salivary Immunoglobulin A (IgA) may be used to provide an alternative/ complementary serological method 5. The effect (if any) of vitamin D supplementation on seroconversion rates stratified by: i) level of baseline vitamin D 'deficiency/ insufficiency/ sufficiency' status; ii) extent of BMI-defined normal/overweight/obesity cut-offs and iii) gender.

The aim of this questionnaire survey is to evaluate the improvement in vision-related quality of life before and after cataract surgery using the National Eye Institute Visual Function Questionnaire 25 and the delay of improvement in the COVID-19 pandemic.

The Primary objective is to explore ambulance service attendance at incidents involving alcohol and/or substance use over the period of the pandemic lockdown, and the following months. This will be to determine prevalence and explore factors such as patient gender, age, ethnicity or location. Analysis will examine the calls over the course of the year prior to the lockdown, and then compare this to the period of lockdown and following months.

The current coronavirus disease pandemic has posed a problem and a challenge for health systems globally. In the framework of a pandemic, a diagnosis is a key tool in containing and monitoring disease outbreaks. In this pandemic, the qPCR technique has become vitally important in virus detection, due to its wide detection and quantification range, and the high levels of sensitivity and specificity it presents. The methodology for diagnosing coronavirus by qPCR requires the prior extraction of viral genetic material, which is carried out using commercial kits created for this purpose. Currently, the high demand for supplies to carry out this technique has generated reagent shortage problems, including commercial kits for the extraction of viral genetic material. This research aims to evaluate a solution called AAA-Safe and its method, developed to optimize the diagnostic process, eliminating and replacing the viral RNA extraction stage. We hope that this alternative can be implemented in any molecular diagnostic laboratory, in order to speed up the delivery of a fast and safe diagnosis.

To measure the effect of Ivermectin (sub-cutaneous) with or without zinc in treating the COVID-19 patients to clear viral load of SARS-CoV-2 along with reduction in severity of symptoms and length of hospitalization of patients with COVID-19.
