Coronavirus Antibody Testing is Coming to Orange County

Published

on

Orange County officials are working with UC Irvine to study how many people have been infected with COVID-19. Researchers will examine blood samples of 5,000 people for antibodies from COVID-19 to understand how many people have contracted the disease throughout the county. 

This month, samples that represent the county population will be examined, and eight to ten drive-through sites will be set up. Pin-prick tests will also be administered to collect blood and sent to UCI for an analysis of the blood samples.

Similar tests have already begun in Los Angeles, and Santa Clara counties, and the number of infections was more significant than the number of confirmed cases. Officials conducting the Orange County examinations expect to have the same result. 

Contrary to the testing administered in Los Angeles and Santa Clara, the UCI study is intended to be more extensive and rigorous by testing more individuals than the other two studies. Researchers will go to the homes of those who cannot go to the drive-through sites and try to reach under-served communities. These efforts will help to have better estimates of disease prevalence by age and race/ethnicity. To observe how subjects’ immune responses change, researchers will follow some subjects over time. 

The director and founding dean for UCI’s Program in Public Health Bernadette Boden-Albala is leading the effort with Tim-Allen Bruckner, an associate professor. The study costs about 1.5 million, the proposal says, and is the largest of three surveillance studies currently in the works at UCI. 

The LRW Group, who led the sample for Los Angeles study, has email, mobile, and land-line information for more than 800,000 adults in Orange County. The LRW Group will be charged with pulling together the sample of 5,000 people that represents the Orange County population. 

Researchers are in the process of finalizing, which finger-prick test to use, and hope to begin testing in the next couple of weeks. After data is collected, the results will be analyzed and aim to be ready for publication by fall. The study will consist of about 200 participants who have tested positive to COVID-19 or for antibodies. The participants will have blood drawn every two weeks over four months

This surveillance study will be sent to the County Board of Supervisors to inform how long to continue restrictive public health measures, identify who is at high risk for the disease, and understand the persistence of the duration of immunological responses

New Study Finds Children Can Spread COVID-19 as Much as Adults

Published

on

A new study from South Korea has discovered that children between the ages of 10 and 19 can spread COVID-19 just as much as adults. The extensive study, published by the Centers For Disease Control and Prevention, states that household transmission of the virus “was high” for those between 10 and 19 years old

Household transmission rates were lower for patients aged 0 to 9. Researchers examined reports for 59,073 contacts of 5,706 coronavirus patients in South Korea between January 20 and March 27. Dr. Ashish Jha, director of the Harvard Global Health Institute, told The New York Times that this study is one of the best to date concerning the coronavirus and transmission of the disease.

The results arrive as school officials across the nation determine whether or not to reopen schools for the upcoming year. The South Korean study said that the researchers’ findings of coronavirus transmission during school reopenings emphasize the need for a time-sensitive epidemiologic study to safeguard public health policy.

The study also indicated the effectiveness of contact tracing, especially in light of future waves of SARS-CoV-2, that will rely heavily upon social distancing and personal hygiene as primary factors for preventative measures. Awareness of the role hygiene and infection control measure plays is vital to reducing the household spread, and using masks in the home for family members who are at high risk for contracting the coronavirus needs further research.

Michael Osterholm, an infectious disease expert at the University of Minnesota, told The New York Times, that there will be transmission rates of the virus if schools reopen and include that in plans for preventing and limiting the contraction of the virus.

Video Laryngoscope Released in the U.S. for Faster Intubation During COVID-19

Published

on

Healthcare facilities worldwide are on the front lines during the ongoing COVID-19 pandemic by providing treatment for patients. Those who are in critical condition in intensive care units need intubation, but this process can be complicated by obtaining an airway precisely. Each patient varies; some can take a minute or more during intubation, potentially leading to fatal consequences. 

Nihon Kohden is launching its NK AWS-S200 video laryngoscope in the United States under the Pentax brand outside the United States. This device is designed to achieve intubation faster and on the first try. Furthermore, the company claims the product “can help protect clinicians while intubating patients suffering from COVID-19 or other respiratory infections”.

The NK AWS-S20 features a high-definition color display targeting cross-hairs that help deliver the working end into the airway. A functioning channel allows for the endotracheal tube to be pushed while viewing the airway properly. 

There is a built-in-channel to guide the endotracheal tube and continuously observe the intubation process. The video laryngoscope can decrease the risk of oral and pharyngeal injury, such as mild mucosal bleeding and sore throat.

Nihon Kohden mentioned that the NK AWS-S200  allows healthcare professionals to intubate challenging patients quicker than other competitor’s devices. The company expressed the device can help clinicians intubate patients with even difficult airways in  22.9 seconds, well below the 30-second threshold suggested for intubations and up to 33 seconds faster than other devices. 

Genoveffa Devers, DNP, MSHA, RN, CPHQ, VP of clinical and strategic alliances at Nihon Kohden stated the importance of tools to establish an airway quickly and efficiently as possible for healthcare providers. She added that the NK AWS-S200 video laryngoscope is designed to attain this while maintaining clinicians’ safety by limiting contact trying to visualize the vocal cords and larynx. 

Using the firm’s disposable NK PBLADE blades, which are available in four different sizes, help clinicians reduce cross-contamination between patients and those providing treatment.

In addition, when administering CPR, the video laryngoscope can be used to intubate patients without delaying life-saving treatment.

‘COVID Symptom Study’ App Tracks Various COVID-19 Symptoms

Published

on

A new smartphone COVID-19 app that tracks symptoms has gathered information from more than 4 million people worldwide and gives doctors the ability to examine the different symptoms patients are experiencing with the virus. The mixture of various symptoms people are exhibiting with COVID-19 is unexpected.

According to Dr. Troy Pennington of Arrowhead Regional Medical Center in Colton, there are various forms of COVID-19 symptoms in patients. The application is called the COVID Symptom Study, was designed by healthcare professionals and scientists at Massachusetts General Hospital, The Harvard T.H. Chan School of Public Health, King’s College London and Stanford University School of Medicine, working beside ZOE, a health science company. Users can input their health information and get statistics on those participating around their region. 

Researchers grouped patients into six different clusters. The first cluster of patients are those experiencing mild symptoms who had flu-like symptoms, according to Pennington. The symptoms included body aches, possibly a sore throat, mild shortness of breath, and mostly mild symptoms, but no fever.

The second cluster of patients displayed similar symptoms, but with a fever. The third group of patients included gastrointestinal issues. Pennington added that there was a GI component with mild diarrhea or even an upset stomach. 

The fourth cluster of patients added severe fatigue, while the fifth added confusion as part of their symptoms. The sixth cluster consisted of patients experiencing the most severe symptoms, including abdominal and respiratory problems. This group had all of the common attributes of flu-like illness, but it had a very significant GI component with persistent abdominal pain and diarrhea. 

Pennington stated some of his patients at Arrowhead Regional Medical Center had exhibited even more peculiar symptoms such as unusual rashes and rashes that also looked like hives or chickenpox. Another patient was complaining of number fingers and toes. 

According to the study, the only common symptoms in all six clusters were headaches and loss of smell.

The COVID Symptom Study app has allowed physicians to get a closer look at COVID-19 symptoms patients experience to help healthcare professionals identify and treat patients accordingly.
