Assessing the Accuracy of Coronary Calcium Scores

A coronary calcium score, measured by a fast CT scan, is a reliable indicator of potential heart artery blockages, especially useful for individuals with risk factors like diabetes. While a high score suggests increased risk, it does not guarantee future blockages, and decisions about medication should be made with a healthcare provider, possibly using tools like the MESA calculator. The test results are generally accurate, and repeat testing is usually unnecessary unless advised by a doctor.

"Uncovering Misdiagnosed Chickenpox Cases in the US"

Due to the success of the chickenpox vaccination campaign in the US, the disease has become so rare that doctors are misdiagnosing it half the time. A report from the Minnesota Department of Health found that only 37 percent of suspected chickenpox cases actually tested positive for the virus, with one-fifth of those cases being 'breakthrough' chickenpox in vaccinated individuals. The study highlights the importance of laboratory confirmation of varicella, especially in vaccinated patients, and suggests that the clinical diagnosis of chickenpox can be unreliable. This diagnostic challenge is a consequence of the significant reduction in chickenpox cases following widespread vaccination.

"Elizabeth Holmes Receives 90-Year Ban from Federal Health Programs"

Elizabeth Holmes, founder of Theranos, has been banned from federal health programs for 90 years following her conviction for fraud related to the inaccurate and faulty blood-testing claims made by her startup. The Health and Human Services Department can exclude individuals convicted of certain felonies from Medicare, Medicaid, and Pentagon health programs, essentially barring them from working in the broader health care system. The ban is a result of "certain aggravating factors" such as the longevity of Theranos' fraud and Holmes' imprisonment. This decision comes after a trial that determined the unreliability of Theranos' testing technology, which had raised hundreds of millions of dollars and involved partnerships with prominent entities before its downfall.

Understanding High Cortisol Levels: A Comprehensive Guide

The concept of high cortisol has become popular on social media platforms like TikTok, with influencers attributing various symptoms like weight gain, poor sleep, and acne to elevated cortisol levels. While high cortisol is a real medical condition, it is important to understand that not all high cortisol is the same. Stress-related cortisol peaks are transient and can be managed through lifestyle changes, while high cortisol caused by underlying diseases like tumors requires medical intervention. It is crucial to consult a healthcare professional for proper diagnosis and testing. Additionally, online supplements and tests claiming to lower cortisol levels are not supported by reliable studies. Managing stress, getting quality sleep, exercising, and finding healthy coping mechanisms are key to maintaining cortisol levels.

"The Enigmatic Beauty of Wet Horseshoe Crab Shells Revealed Up Close"

Horseshoe crabs, ancient creatures that appear fossilized, are being bled for their milky blue blood, which is used to detect toxins in medicine. Half a million horseshoe crabs are caught and drained of a third of their blood each year. The crabs are yanked from the water, transported to bleeding facilities, and injected with a needle to extract their blood. The eggs of these prehistoric creatures, laid during spawning events, hold small green creatures that seem to delight in somersaulting against their eggshells. Horseshoe crabs play a crucial role in medical testing, protecting millions of people who receive flu shots, childhood immunizations, heart stents, or hip replacements.

Testing company's error causes cancer scare for hundreds

More than 400 people who signed up for Grail Inc.'s early-warning cancer test were mistakenly told they likely had the disease due to a "software configuration issue" by telemedicine vendor PWNHealth. The warnings were sent to half of the trial testing participants, some of whom had not even had their blood drawn yet. Grail confirmed that the software mishap had been resolved and was not related to an incorrect Galleri test result. The mistake has caused concern among some insurers involved in the trials.

FDA Eases Blood Donation Restrictions for Gay and Bisexual Men

The FDA has updated its guidelines for blood donors, allowing gay and bisexual men in monogamous relationships to donate blood without abstaining from sex. The new approach evaluates individual risks for HIV based on sexual behavior and recent partners, rather than sexual orientation. Potential donors who report having anal sex with new partners in the last three months will be barred from giving until a later date. The FDA noted that anyone who has ever tested positive for HIV will continue to be ineligible to donate blood.

Discover Your Blood Type: A Guide for Americans.

Nearly a third of Americans don’t know their blood type, which can be useful during an emergency or when donating blood. Blood tests, blood donations, at-home testing kits, and saliva tests can all determine blood type, but some options are more reliable than others. Knowing your blood type can help you understand your general health and is critical information for specific situations, such as surgery or pregnancy. The most common blood type is O-positive, while O-negative is the universal donor and AB-positive is the universal recipient. The best ways to find out your blood type are to ask your healthcare provider or donate blood.
