The risk of developing venous thromboembolisms—potentially serious blood clots in the veins—is elevated among cancer patients hospitalized with COVID-19 and taking anticancer drugs, according to a study yesterday in JAMA Oncology.

How COVID-19 Changes the Immune System
In a paper published on August 18 in the journal Cell, scientists report that innate immune cells—a critical part of the immune system activated to battle COVID-19—remain altered for at least a year after infection. The finding suggests that these cells may play a role in some of the lingering symptoms associated with Long COVID, although more studies are needed to confirm that connection.

COVID-19 took a toll on heart health and doctors are still grappling with how to help
Heart attack-caused deaths rose during every virus surge. Worse, young people aren’t supposed to have heart attacks but Cheng’s research documented a nearly 30% increase in heart attack deaths among 25- to 44-year-olds in the pandemic’s first two years.

In a new study, researchers used Medicare data to characterize the long-term risk of death and hospital readmission after being hospitalized with COVID-19 among patients 65 years and older. The study demonstrates that among patients who were admitted to a hospital with COVID-19 and discharged alive, the risk of post-discharge death was nearly twice that observed in those who were discharged alive from an influenza-related hospital admission.

Researchers find COVID-19 causes mitochondrial dysfunction in heart and other organs
This study provides us with strong evidence that we need to stop looking at COVID-19 as strictly an upper respiratory disease and start viewing it as a systemic disorder that impacts multiple organs. The continued dysfunction we observed in organs other than the lungs suggests that mitochondrial dysfunction could be causing long-term damage to the internal organs of these patients.

Scientists develop breath test that rapidly detects COVID-19 virus
Comments closedWith this test, there are no nasal swabs and no waiting 15 minutes for results, as with home tests. A person simply blows into a tube in the device, and an electrochemical biosensor detects whether the virus is there. Results are available in about a minute.

What’s the future of wastewater testing for COVID‑19?
Wastewater surveillance became an important tool for detecting COVID-19 outbreaks in communities throughout the pandemic, and it continues to be used in search for coronavirus SARS-CoV-2 as well as other pathogens.
But it’s unclear whether current levels of government funding to monitor wastewater for SARS-CoV-2 will continue beyond next year. Experts are calling on the federal government to create a standardized system for wastewater surveillance to bolster and replace the patchwork being used today.

Hospital-acquired COVID infections worsened as the pandemic progressed, research finds
The chances of becoming infected with COVID-19 while hospitalized increased as the pandemic progressed, according to recent Canadian research.
In fact, significantly more Canadians became infected with hospital-acquired COVID-19 during the fifth and sixth waves of the pandemic — the first two Omicron waves from late 2021 until the spring of 2022 — than during earlier waves, according to the study published in the journal JAMA Network Open. Researchers looked at cases of patients hospitalized with COVID-19 between March 2020 and May 2022.

Study: 1 in 6 kids have persistent COVID symptoms for 3 months after infection
Comments closedIt was thought at first that the pediatric population was relatively spared from the long-term effects of COVID-19 after infection. But this changed rapidly with increasing reports and studies of pediatric patients not fully recovering from acute COVID-19.

Long COVID presents ‘unfathomable’ burden as health-care system reaches ‘boiling point’
Dr. Jennifer Hulme thought her COVID-19 infection was just “average.” She recovered in a matter of days and went back to work.
Several weeks later she was incapacitated.
“I woke up completely disabled, profoundly ill (and) completely changed from my previous self,” the Toronto emergency room doctor said.

The list of neurocognitive issues that Meropol’s team and other researchers must track is extensive: cognitive decline, changes in brain size and structure, depression and suicidal thinking, tremors, seizures, memory loss, and new or worsened dementia have all been linked to previous SARS-CoV-2 infections. In some cases, these longer-term problems occur even in patients with relatively mild COVID-19.
