1. Cannabis use raises risk of heart attack and stroke more than cocaine, other drugs, major review suggests
Recent research, including a meta-analysis by French researchers published in the journal Heart, has highlighted the potential negative health effects of cannabis use, particularly on cardiovascular health. The analysis, which reviewed data from over 400 million patients in 24 previous studies, found a significant increase in the risk of major adverse cardiovascular events (MACE) associated with cannabis use. The risks included a 29% higher likelihood of heart attack, 20% higher risk of stroke, and double the chances of cardiovascular death, especially among those who used cannabis at least once a week. Studies also showed higher odds of heart attack, with increased risks observed in younger populations and frequent users. Additionally, cannabis was found to be a larger predictor of heart attack compared to other illicit drugs like cocaine and opioids, and daily marijuana smokers faced a higher risk of heart attack and stroke.
The findings suggest a connection between cannabis use and MACE, urging further investigation into cannabis use in patients with serious cardiovascular disorders. While medical marijuana can offer relief for certain conditions, overuse has been linked to potential health risks, particularly for seniors. Limitations in the studies included poor reporting of cannabis exposure, potential biases, and overlapping data. Dr. Marc Siegel, a Fox News senior medical analyst, warned about the dangers of regular cannabis use, emphasizing its potential to increase anxiety, discombobulation, and health issues like dementia. He compared the effects of marijuana to smoking cigarettes in terms of heart and lung damage, cautioning against the increasing trend of seniors using cannabis despite the associated risks.
2. FDA approves first twice-yearly injection that prevents HIV infection
The U.S. FDA approved a new injectable HIV prevention shot named Yeztugo, created by Gilead Sciences, which is administered twice a year. The drug, lenacapavir, reduces the risk of sexually acquired HIV in adults and adolescents, marking a significant advancement in the fight against HIV. Gilead claims that lenacapavir has shown remarkable outcomes in clinical studies and could transform HIV prevention, with trials indicating nearly 100% effectiveness in preventing HIV. The drug is given as an injectable under the skin and individuals must test negative for HIV-1 before starting treatment. Lenacapavir’s multi-stage approach sets it apart from other antiviral medications, inhibiting HIV at various stages of its lifecycle, making it a crucial breakthrough in ending the HIV epidemic.
3. Your DNA could be stopping you from losing weight, new study suggests
A recent study from Harvard T.H. Chan School of Public Health and Ben Gurion University in Israel revealed that genetic factors may play a role in preventing weight loss, even with a healthy diet. The study focused on 761 individuals with abdominal obesity who were put on various healthy diets for 18 to 24 months. Results showed that 36% of participants achieved significant weight loss, while 28% did not lose any weight. Interestingly, those who did not lose weight still experienced health improvements, such as better cholesterol levels and reduced visceral fat. The lead author of the study emphasized that weight loss is not the only measure of success, as improving metabolism and reducing disease risk are also important outcomes.
4. Invasive pests could stage dramatic comeback this summer, experts warn
Experts are warning of a potential surge in spotted lanternfly populations this year, based on increased egg mass counts in Pennsylvania. The lanternflies, while not harmful to humans or animals, pose a serious risk to plants and crops, potentially affecting agricultural production. The invasive insect, known for feeding on over 70 plant species, can cause harmful mold growth on plants through their excretions. The lanternfly prefers the tree of heaven but is an indiscriminate pest that can impact forest ecosystems and cultural resources once established in an area. People are advised to be vigilant as lanternfly activity increases, especially in regions where the insect is spreading, like the Midwest and Southeast.
