Filter by:At the beginning of 2020, a global alert emerged which saturated intensive care units due to COVID-19 worldwide. This caused a need for mechanical ventilation due to atypical pneumonias that had a rapid evolution and respiratory failure; therefore the consumption of sedative agents in the intensive care units escalated. Suboptimal sedation in the intensive care unit, increases the adverse effects, costs, and morbidity. For the time being, they focus on the use of intravenous agents such as propofol or dexmedetomidine, which are associated with tolerance, withdrawal, delirium, and hemodynamic effects. Consequently, the need arises to maximize availability and effectiveness, which is why the intervention of the ANACONDA conservation device is carried out, which works with a heat and humidity exchange filter capable of administering isoflurane or sevoflurane with an efficiency of 90%.
The SARS-CoV-2 pandemic has consisted of multiple surges of infection because of continuous viral mutations. The WHO and CDC have defined the main SARS-CoV-2 variants based on international and national data for the circulation of SARS-CoV-2 into at least 4 waves. Studies from different parts of the world have demonstrated significant variations in the clinical manifestations of viral infection in relation to different SARS-CoV-2 variants. They also indicated that the current high levels of population immunity, due to prior infection and/or vaccination, have been associated with a vastly decreased overall risk of severe disease. Anosmia (with or without ageusia) was identified as a hallmark of COVID-19 early in the pandemic (ancestral Wuhan strain, alpha and delta variants), with a prevalence of ~60%. Prolonged olfactory disorders, lasting ≥6 months to years, has been reported in ~35-40% of infected individuals. However, studies reported that olfactory and gustatory disorders were less frequent with Omicron variants compared to pre-omicron variants. It has been indicated that SARS-CoV-2 can cause destruction, disorganization and molecular changes in the nasal olfactory neuroepithelium resulting in loss and distortion of the sense of smell. There are several trials to treat these persistent disorders but none has shown significant positive results except ours (Hamed et al., Expert Review of Clinical Pharmacology 2023;16(12):1261-1276 DOI: 10.1080/17512433.2023.2282715). Hamed et al. reported that cerebrolycin, a commercially available multimodal neurotropic factor, has the ability to cure at least 60% (100% complete and persistent recovery) of post-covid-19 persistent olfactory and gustatory dysfunctions. This drug is available in the market of at least 75 countries since 1996 and easily dispensed from local pharmacies after doctors prescriptions. It is used for treatment of many disorders of the central and peripheral nervous systems. This could be due to its ability to promote neurogenesis and remodeling of olfactory and gustatory neurons.
The goal of this decentralized, observational study is to enroll and observe adults in the contingent United States during the 2023-2024 flu season. The main study objectives are to create a dataset of paired wearable data, self-reported symptoms, and respiratory viral infection (RVI) from PCR testing during the 2023-2024 flu season and to develop algorithm that is able to accurately classify asymptomatic and symptomatic RVI and understand the algorithm's performance metrics.
This study is a randomized, double-blind, placebo controlled clinical exploratory study to evaluate the safety, tolerability and immunogenicity of TI-0010 vaccine in healthy adults aged 18-59. TI-0010 was manufactured by Therorna Inc. TI-0010 is a novel lipid nanoparticles (LNP) -encapsulated circRNA-based vaccine targeting RBD of SARS-CoV-2. Up to one hundred subjects will be enrolled into one of 4 cohorts. Low-dose(Dose Level 1) is for Cohort 1 and Cohort 2 , and the high dose (Dose Level 2) for Cohort 3 and Cohort 4. Cohort 1 and Cohort 3 receive 2 doses (with a 28 day interval) via intramuscular injection respectively, and Cohort 2 and Cohort 4 receive 1 dose via intramuscular injection respectively. Participants are randomized to receive TI-0010 or placebo in a 4:1 ratio.
The goal of this pilot study is to assess the feasibility and impact of using sodium citrate nasal spray as an adjunct to olfactory retraining in participants with long-term post-COVID-19 olfactory dysfunction. The main questions it aims to answer are: - Is sodium citrate nasal spray in addition to smell retraining feasible for participants to use in terms of participant need/desire, adherence, and adverse events? - Does sodium citrate nasal spray in addition to smell retraining further improve smell as compared to normal saline spray and smell retraining? Participants will: - Provide consent for enrollment. - Undergo smell testing via Sniffin' Sticks. - Use a nasal spray (either sodium citrate or normal saline) followed by olfactory retraining twice a day for 12 weeks. - Return for follow-up Sniffin' Sticks testing. Researchers will compare the sodium citrate group and the normal saline group to determine differences in smell improvement.
The goal of this observational study is to learn about the correlation between COVID-19 and hyperthyroidism in Patients with hyperthyroidism complicated with COVID-19. The main questions it aims to answer are： - The main research object is Graves disease (GD) patients. - Changes of hyperthyroidism in GD patients complicated with COVID-19 - Changes of anxiety and depression in GD patients before and after SARS-CoV-2 infection. - The effect of psychological intervention in GD patients after COVID-19. Participants will have regular follow-upfor one year to hyperthyroidism in our hospital, and the investigators will collect the thyroid function and related examination indexes of patients in the corresponding time period.
Since December 2019, a new coronavirus, SARS-CoV-2, has been identified in the city of Wuhan in Hubei province in China and is the cause of a global pandemic. This highly contagious virus is responsible for the COVID-19 disease, the manifestations of which can range from a simple flu-like syndrome to acute respiratory distress syndrome (ARDS). Transmission of SARS-CoV-2 is mainly linked to droplets. The mode of transmission of SARS-CoV-2 involves at least droplet-type isolation for caregivers with wearing a surgical mask and extended contact type (overcoats, caps, gloves). During procedures with a high risk of aerosolization of viral particles (intubation, aerosols, aspirations, nasopharyngeal swabs), wearing an FFP2 mask and protective glasses are recommended. In addition, oxygen therapy, particularly at a flow rate greater than 6 L/min, could also lead to airborne contamination. The occupational risk of contamination of health professionals is well identified, particularly in Chinese but also Italian studies. In Italy, 20% of healthcare workers have been contaminated. In China, a rate of 3.5 to 29% in Wuhan hospitals has been identified. Among the professionals exposed within the hospital, those in emergency services are part of the category with the greatest risk of contamination along with those in intensive care units. Recommendations from experts from the French intensive care society and foreign companies made it possible to identify the situations most at risk of contamination. In addition, the organization has made it possible to better understand patient care circuits in order to limit the risks of contamination. However, procedural errors may exist, implying the need for frequent training sessions for professionals. In addition, if the recommendations specify the need to obtain negative pressure in the rooms or at least zero, the material limits linked to reception in emergency departments with the need for intubation of a significant number of patients sometimes makes it difficult to carry out these risky actions under optimal conditions. Finally, the methods of sorting suspected cases to organize care in areas different from other emergency patients do not prevent assignment errors, a source of contamination for caregivers and patients. Thus, health professionals are among the priority people to be screened in accordance with the recommendations of the High Authority of Health. Indeed, even if symptomatic healthcare workers were mostly screened at least by taking a nasopharyngeal swab, some healthcare workers were able to develop immunity to the disease without having been symptomatic. The number of asymptomatic cases of COVID-19 is significant, but the proportion is not yet clearly identified. In addition, massive screening of symptomatic and non-symptomatic healthcare workers would make it possible to reduce the number of nososcomial contamination. Determining the serological status of healthcare workers is a priority, particularly in services on the front line of caring for patients with COVID-19, such as emergency structures.
The primary purpose of this study is to learn about how well different versions of the Pfizer-BioNTech COVID-19 vaccine (called BNT162b2) work at preventing death, severe COVID-19 that requires a trip to the hospital, and overall use of healthcare resources, such as needing to go the doctor or urgent care due to illness. Pfizer is not enrolling any participants for this study. Instead, existing data from different health data sources will be used to help answer the scientific questions Pfizer is interested in learning more about.
Following the introduction of the COVID-19 vaccination, elective surgeries have resumed, allowing for greater insight into the postoperative period and outcomes aims on-going COVID-19 infections. This study aimed to evaluate risk factors of postoperative morbidity and mortality in patients who had surgery within one year of testing positive for COVID-19.
We conducted an observation sub-study of the prospective randomized controlled trial "High Dose Inhaled Nitric Oxide in Acute Hypoxemic Respiratory Failure", in which we analysed the echocardiographic data collected both at baseline when patients where included and 3-5 days later for followup.
