Months after hospitalization for COVID-19, MRIs reveal multiorgan damage
This study found abnormal MRI results in 20% to 25% of both controls and hospitalized patients, suggesting
“a lot of these cardiac abnormalities that were seen in the COVID group must have been there beforehand.” Post–COVID-19 patients with lingering cardiac symptoms might have disorders like heartbeat irregularities that aren’t always visible with MRI, or dysfunction in other organs, he adds.
Although it can offer clues to an organ’s health, MRI is an imperfect measure of how a patient is faring after infection. Researchers found no connection between abnormal liver MRIs and symptoms such as gastroin...

Increasing SARS-CoV-2 seroprevalence among UK pediatric patients on dialysis and kidney transplantation between January 2020 and August 2021
ConclusionsAnti-SARS-CoV-2 seroprevalence was low in 2020 and increased in early 2021. Serological surveillance complements nucleic acid detection and antigen testing to build a greater picture of the epidemiology of COVID-19 and is therefore important to guide public health responses.Graphical abstractA higher resolution version of the Graphical abstract is available asSupplementary information

Shape Anisotropy ‐Governed High‐Performance Nanomagnetosol for In Vivo Magnetic Particle Imaging of Lungs
Magnetic particle imaging (MPI) offers high contrast, sensitivity, and signal-to-noise ratios for lung imaging, enhancing theranostic strategies in respiratory disease. Innovations in MPI tracers promise further gains, bolstering clinical applicability. This work introduces a superior nanotracer, leveraging magnetic nanoparticle shape anisotropy, elevating sensitivity and resolution beyond conventional spherical counterparts for lung MPI. AbstractCaused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), coronavirus disease 2019 (COVID-19) has shown extensive lung manifestations in vulnerable individuals, putt...

Dietary supplements to reduce symptom severity and duration in people with SARS-CoV-2: a double-blind randomised controlled trial
Background
COVID-19 has caused morbidity, hospitalisation and mortality worldwide. Despite effective vaccines, there is still a need for effective treatments, especially for people in the community. Dietary supplements have long been used to treat respiratory infections, and preliminary evidence indicates some may be effective in people with COVID-19. We sought to evaluate whether a combination of vitamin C, vitamin D3, vitamin K2 and zinc could improve overall health and decrease symptom burden in outpatients diagnosed with COVID-19.
Methods
Participants were randomised to receive either vitamin C (6 g), vitamin D3 (1000...

Collective aeromedical evacuations of SARS-CoV-2-related ARDS patients in a military tactical plane: a retrospective descriptive study
After the appearance of the COVID-19 pandemic in France, MEROPE system was created to transform the military tactical ATLAS A400M aircraft into a flying intensive care unit. Collective aeromedical evacuations (aero-MEDEVAC) of patients suffering from SARS-CoV-2-related acute respiratory distress syndrome was performed from June to December 2020. A total of 22 patients were transported during seven missions. All aero-MEDEVAC was performed in safe conditions for patients and crew. No life-threatening conditions occurred during flight. Biohazard controls were applied according to French guidelines and prevented crew contamina...

Simultaneous Targeting of IL-1-Signaling and IL-6-Trans-Signaling Preserves Human Pulmonary Endothelial Barrier Function During a Cytokine Storm
CONCLUSIONS: These findings strongly suggest a major role for both IL-6 trans-signaling and IL-1β signaling in the pathological increase in permeability of the human lung microvasculature and reveal combinatorial strategies that enable the gradual control of pulmonary endothelial barrier function in response to a cytokine storm.PMID:37732482 | DOI:10.1161/ATVBAHA.123.319695

Effects of pulmonary rehabilitation in survivors of severe acute respiratory syndrome coronavirus 2. Role of vaccination
Monaldi Arch Chest Dis. 2023 Sep 18. doi: 10.4081/monaldi.2023.2738. Online ahead of print.ABSTRACTSurvivors of severe COVID-19 requiring hospital admission may suffer from short- and long-term sequelae, including disability and reduced physical performance. Vaccination and pulmonary rehabilitation (PR) are effective tools against COVID-19 effects. While the beneficial effect of each of these treatments is known, there are no data about their combined effect. In people admitted to PR hospitals after severe COVID-19 disease, we retrospectively analyzed whether PR outcome might be influenced by vaccination status. Ninety-six...

Evaluation of concentration procedures, sample pre-treatment, and storage condition for the detection of SARS-CoV-2 in wastewater
Environ Sci Pollut Res Int. 2023 Sep 21. doi: 10.1007/s11356-023-29696-y. Online ahead of print.ABSTRACTCrucial information on the pandemic's spread has been gathered by monitoring the trend of SARS-CoV-2 in wastewater. This surveillance has highlighted that the initial concentration is a critical step of the analytical procedure due to the low viral titer that may be present in this matrix. This paper presents the results of the evaluation of two different wastewater concentration protocols to determine the most efficient and cost-effective. The two methods tested were the following: (a) a biphasic separation system with ...
