A new study, supported by the National Institutes of Health, found that machine learning models were able to identify patterns in patient data that indicate a higher risk of developing COVID-19. Other reports highlight the sometimes-overlooked symptoms and impact of COVID-19.
CIDRAP: Machine Learning Models May Detect Patients at Long-Term Risk of COVID-19
Machine learning models created by a research team backed by the National Institutes of Health (NIH) can identify patients who are likely to have been infected with the coronavirus for a long time with high accuracy, according to a study published yesterday in The Lancet Digital Health. … The three machine learning models are designed to detect symptom patterns, healthcare use, demographics, and prescriptions to identify all COVID-19 patients likely to present with long-term symptoms, including both in-hospital and non-hospital.

The Lancet Digital Health: Identifying who has had COVID for a long time in the US: A machine learning approach using N3C data
Using the National COVID Cohort Collaborative (N3C) Electronic Health Records Repository, we developed XGBoost machine learning models to identify potential COVID-19 patients for a long time. (Pfaff et al., 5/16)
Boston.com: Harvard economist on ‘long coronavirus costs’: ‘we should worry about it’
Even as some of the effects of COVID-19 on daily life wear off, the pandemic still grips the economy, according to a Harvard economist. Specifically, David Cutler, a Harvard economics professor who focuses on health economics, said the novel coronavirus has the potential to have widespread and long-term effects on the economy.

The Wall Street Journal: Symptoms of COVID-19 often include severe fatigue. Here’s how to deal
New York City’s 53-year-old Ken Todd ran 18 marathons before contracting COVID-19 last year. Now, going out to lunch with friends exhausts him. “I basically need to plan to lie down when I get home for the rest of the day,” says Mr. Todd. He is among many Covid patients suffering from fatigue months after the initial infection. Doctors say many, like Mr. Todd, suffer not only from fatigue but also from a syndrome called post-exercise malaise. Some Covid patients have long been trying to cope with fatigue, a decision that is often counterproductive and increases fatigue and other symptoms. (Ready, 5/16)
KHN: This is just part of aging: Long-term COVID-19 symptoms often overlooked in older adults
Nearly 18 months after contracting covid-19 and spending weeks in the hospital, Terry Bell struggles to get his shirts and pants off after washing clothes. Picking up his clothes, lifting his arms, and arranging things in his wardrobe makes him short of breath and often leads to extreme fatigue. Walks with a stick, only short distances. He’s 50 pounds lighter than he was when he contracted the virus. Bell, 70, is among the millions of older adults who have struggled with the coronavirus for extended periods – a demographic that has received little attention even though research suggests that older adults are more likely to have a poorly understood condition than younger or middle-aged adults.

Hill: Five things to know about the long-running coronavirus
It is generally believed that patients who have developed severe cases of COVID-19 or have had to be hospitalized are more likely to develop long-term symptoms after recovering from the initial infection. However, studies have indicated that a significant proportion of asymptomatic COVID-19 cases lead to prolonged COVID-19. (Choi, 5/17)

CIDRAP: Estrogen therapy linked to reduced COVID-19 deaths
Women who received prescriptions for estrogen hormone replacement therapy (HRT) within 6 months of being diagnosed with COVID-19 reduced the death rate, according to a new study in Family Practice. The findings, along with data on gender differences between male and female COVID-19 severity, suggest that estrogen may have a protective role against the virus. (Socheri, 5/17)
KHN: How Better Ventilation Can Help Your Home ‘Resist Covid’
For two years, I beat the odds. You’re convincing, you keep your distance, and you get your shots. Now, despite these efforts, you, your child, or anyone else in your household has contracted Covid-19. And the last thing you want is for the virus to spread to everyone in the family or home. But how do you keep it from spinning when you live nearby? (Szabo, 5/18)
Roll’s Call: COVID-19 Wastewater Efforts Face Long-Term Questions
In February 2020, environmental engineers Aaron Bivens and Kyle Beebe launched an informal collaboration with a few fellow researchers, hoping to share tips and strategies about monitoring wastewater for signs of the COVID-19 pandemic. By April 2022, this group had swelled to more than 1,300 analysts and professionals worldwide, with a Slack account promoting new research and making introductions—all part of an effort to facilitate early information sharing that did not exist at the federal level.

CIDRAP: Trained scent dogs detect airline travelers with COVID-19
At Helsinki-Vantaa International Airport, dogs sniffed skin swabs from 303 incoming passengers that were also tested for COVID-19 using polymerase chain reaction (PCR) from September 2020 to April 2021. – Coronavirus 2 with 92% sensitivity, 92% sensitivity, specificity 91%. The team said they were much less accurate in detecting infection caused by the alpha variant (89% for the wild-type virus versus 36% for alpha. But the latest result also shows how well dogs can distinguish between different odors. Great because it demonstrates the strong discriminatory power of scent dogs .” (Van Besekum, 5/17)

ProPublica: The COVID Testing Company That Missed 96% of Cases
“These parents were very adamant that their child was not a condition and that they were able to play,” said Heather Kerwin, director of the Washoe County Health Epidemiology Program. back pattern. Athletes will test positive in the rapid test. But before the contact tracer could connect, parents were learning from the testing company that their children’s polymerase chain reaction (PCR) tests, usually the gold standard for COVID-19 testing, were negative, even for students with symptoms. Kerwin investigated and learned that the University of Nevada Reno campus is seeing similar conflicting results. There was something in common between the university and the school district. Both recently hired the same company to run their tests: Northshore Clinical Labs. (Damon 5/17).
New Hampshire Bulletin: Remember the million COVID tests sent to NH liquor stores? Most of them are still not sold.
The one million COVID-19 tests ordered by the New Hampshire Department of Health and Human Services in January for sale at state liquor stores didn’t quite fly, leaving about 926,000 tests available. The department has asked the Joint Legislative Finance Committee for permission to send many of the surplus to health centers, schools, camps and childcare programs. In her request, Health and Human Services Commissioner Lori Shipnet said sales of $11.29 tests have slowed at liquor stores as tests become available elsewhere. That was not the case in January when the administration purchased the tests using $12 million in federal pandemic relief funds. (Timins, 5/17)
