News at a glance: A win for obesity drugs, NIH unionization roadblocks, and Mexican fireflies under threat
CONSERVATION Researchers raise alarm over threat to Mexican fireflies Scientists from the International Union for Conservation of Nature (IUCN) last week delivered a letter to the Mexican government requesting it regulate tourism centered on the threatened firefly species Photinus palaciosi . Endemic to Mexico’s Tlaxcala forests, P. palaciosi is one of the few species that glow in synchrony, offering an annual spectacle that attracts thousands of visitors during summer mating season. The letter describes how littering, artificial light, and noise interfere with the insects’ courtship and eg...

COVID-19 ’ s Impact on Heart Health Still Confounds Doctors
(ST. LOUIS) — Firefighter and paramedic Mike Camilleri once had no trouble hauling heavy gear up ladders. Now battling long COVID, he gingerly steps onto a treadmill to learn how his heart handles a simple walk. “This is, like, not a tough-guy test so don’t fake it,” warned Beth Hughes, a physical therapist at Washington University in St. Louis. [time-brightcove not-tgx=”true”] Somehow, a mild case of COVID-19 set off a chain reaction that eventually left Camilleri with dangerous blood pressure spikes, a heartbeat that raced with slight exertion, and episodes of intense chest pain...

Testosterone Treatments Aren ’ t Linked to Heart Risks When Patients Are Carefully Monitored, Study Finds
Advertisements for treatments for “low T,” or low testosterone levels in middle-aged and older men, have led to spikes in demand. But the safety and legitimacy of those testosterone therapies hasn’t been clear. In a new study published in the New England Journal of Medicine and presented at the Endocrine Society’s annual meeting, researchers provide the most conclusive evidence yet that testosterone treatments appear to be safe for the heart and are not associated with an increased risk of certain heart-related events. In the study, led by researchers at the Cleveland Clinic, more than 5,200 men age...

What to Know About High Triglycerides
Discussions about heart health often center around blood pressure and cholesterol, with factors like poor sleep, smoking, family history of heart disease, and chronic stress thrown in. However, there’s one variable that doesn’t get covered as often, even though it can be an important indicator of cardiovascular risk: triglycerides. “We don’t really talk about triglycerides very much, especially compared to cholesterol, but they’re actually an essential part of understanding heart health,” says Dr. Adriana Quinones-Camacho, a cardiologist at NYU Langone Health in New York. “For some...

How AI Is Changing Medical Imaging to Improve Patient Care
That doctors can peer into the human body without making a single incision once seemed like a miraculous concept. But medical imaging in radiology has come a long way, and the latest artificial intelligence (AI)-driven techniques are going much further: exploiting the massive computing abilities of AI and machine learning to mine body scans for differences that even the human eye can miss. Imaging in medicine now involves sophisticated ways of analyzing every data point to distinguish disease from health and signal from noise. If the first few decades of radiology were about refining the resolution of the pictures taken of...

Plasma epoxyeicosatrienoic acids and diabetes-related cardiovascular disease: The cardiovascular health study
EBioMedicine. 2022 Aug 2;83:104189. doi: 10.1016/j.ebiom.2022.104189. Online ahead of print.ABSTRACTBACKGROUND: Epoxyeicosatrienoic acids (EETs) are metabolites of arachidonic acid that may impact atherosclerosis, and animal experimental studies suggest EETs protect cardiac function. Plasma EETs are mostly esterified to phospholipids and part of an active pool. To address the limited information about EETs and CVD in humans, we conducted a prospective study of total plasma EETs (free + esterified) and diabetes-related CVD in the Cardiovascular Health Study (CHS).METHODS: We measured 4 EET species and their metabolites, dih...

People With Diabetes Are More Vulnerable to Heart Disease. How to Reduce the Risk
If you’ve been diagnosed with diabetes, know that you’ve got plenty of company. The American Diabetes Association (ADA) reports that in 2019, the most recent year for which data is available, 37.3 million adults in the U.S.—about 11.3% of the population—had the chronic condition, and that number continues to grow. Type 1 diabetes develops when the body isn’t able to produce insulin, and Type 2 occurs when the body doesn’t use insulin correctly. Type 2 is the most common form of diabetes, and when it’s uncontrolled, a person’s blood sugar can jump to dangerous levels that requ...

Efficacy and Safety of Recombinant Human Prourokinase in Acute Ischemic Stroke: A Phase IIa Randomized Clinical Trial
AbstractRecombinant human prourokinase (rhPro-UK) is a novel thrombolytic that has been approved to treat patients with acute myocardial infarction. However, the safety and efficacy of intravenous rhPro-UK in patients with acute ischemic stroke (AIS) has not been well established. We aimed to investigate the safety and preliminary efficacy of rhPro-UK in patients with AIS in a multi-center phase IIa trial setting. One hundred nineteen patients within 4.5  h of AIS onset were enrolled in this randomized, open-label, 23-center phase IIa clinical trial. Patients were randomly assigned to 35 mg (n = 40) or 50 mg (n =â...

Tomato concentrate could help reduce chronic intestinal inflammation associated with HIV
New UCLA-led research in mice suggests that adding a certain type of tomato concentrate to the diet can reduce the intestinal inflammation that is associated with HIV. Left untreated, intestinal inflammation can accelerate arterial disease, which in turn can lead to heart attack and stroke.The findings provide clues to how the altered intestinal tract affects disease-causing inflammation in people with chronic HIV infection, suggesting that targeting the inflamed intestinal wall may be a novel way to prevent the systemic inflammation that persists even when antiviral therapy is effective in controlling a person ’s HIV.Th...

Deceleration capacity for rapid risk stratification in patients suffering from acute ischemic stroke: A prospective exploratory pilot study
Deceleration capacitiy for rapid risk stratification in stroke patients Cerebral ischemia is a major cause of neurologic deficit and patients suffering from ischemic stroke bear a relevant risk of mortality. Identifying stroke patients at high mortality risk is of crucial clinical relevance. Deceleration capacity of heart rate (DC) as a parameter of cardiac autonomic function is an excellent predictor of mortality in myocardial infarction and heart failure patients. The aim of our study was to evaluate whether DC provides prognostic information regarding mortality risk in patients with acute ischemic stroke. From ...

Statins do not cause muscle aches and pains, study finds
UK researchers seek to dispel concerns over pills prescribed for those at higher risk of heart attack and strokesStatins are generally not the cause of the muscle aches and pains that stop some people taking the pills prescribed to protect them against serious heart problems, according to a novel study that hopes to dispel some of the concerns.Two million people in the UK who are at higher risk of heart attack and strokes are eligible for statins, but many people refuse them or have stopped taking them because of sometimes alarming and widespread reports of muscle pain. But the study funded by the National Institute of Hea...
