The authors of a Transfusion commentary argue that forgoing routine lab tests may compromise patients' health more than any reduction in the risk of transmission. Experts recommend implementing well-characterized infection prevention and control recommendations to provide a safe environment for both patients and employees.
Researchers identified a genetic susceptibility factor for UV tanning dependence, with variations in the PTCHD2 gene linked to increased risk. The study of over 319,000 participants highlights the importance of genetics in shaping individual responses to UV exposure.
Research published in Global Biogeochemical Cycles analyzed rain samples from Bermuda to investigate the origin of oceanic nitrogen. The authors found that certain nitrogen isotopes likely represent ammonium recycled from the ocean rather than inputted from human activities.
Research on ozone depletion reveals devastating effects on Southern Hemisphere weather, including increased incidence of floods, droughts, wildfires, and changes to tree growth rates and biodiversity in Antarctic lakes. Ozone hole impacts are also felt through changes in summer rainfall and wind patterns, posing risks to natural ecosys...
Among survivors of the 2011 Utøya Island terrorist attack, most perceived contact with media as a positive experience. However, negative evaluations and regrets about participation were found to be associated with post-traumatic stress reactions.
A new long-term clinical trial found that Lung Volume Reduction Coil treatment is safe over a 3-year period. Half of the patients showed continued improvement in lung function capacity and overall quality of life.
Researchers have discovered that blocking blood-brain barrier proteins increases riluzole's effectiveness in treating ALS. The study found improved muscle function and prolonged survival in mice with blocked barriers.

Researchers discovered that fondaparinux, an anticoagulant, can protect transplanted kidneys from damage. Improved kidney function was observed both immediately after transplantation and months later, suggesting this strategy could augment the pool of available organs.
Researchers created a global model of CO2 uptake using fine-scale observations, finding strong interannual variations and the Pacific Ocean dominating flux variability. The study's lead author notes that shipboard measurements provide key data for estimating ocean CO2 sink variability.
A new study suggests that individuals with more severe asthma may be more motivated to lose weight, making them a key target for intervention. Gender tailoring of weight loss programs could also enhance success rates among adults with asthma.
A recent investigation explored whether Facebook murders were unique and worthy of a new label. The study found that these crimes followed typical patterns, with victims knowing their killers, and social media played no more significant role than other tools in the commission of violence.
A study found that middle-aged men whose parents were older at birth had lower blood pressure, more favorable cholesterol levels, and improved glucose metabolism. Further research is needed to determine the causes of this effect, with epigenetics and post-natal factors being potential explanations.
Researchers have designed peptides to target Ebola's N-trimer protein, allowing for universal inhibition across all known and future strains. This approach enables the selection of effective drugs that block virus entry into cells.
Researchers found that older patients with Alzheimer's or cancer were less likely to receive intensive procedures at the end of life. In contrast, black patients in high-hospital-intensity regions were more likely to undergo these procedures.
A new theory proposes that preeclampsia is caused by the body's response to insufficient oxygen and nutrient supply to the growing fetus, leading to high blood pressure and organ damage. The condition can have fatal complications for pregnant women and their babies if left untreated.
Research found that babies born to mothers with rheumatoid arthritis have lower fetal growth and are more likely to be born prematurely. Studies show a 1.5 times higher risk of preterm birth in children exposed to maternal or preclinical RA compared to those without exposure.
Researchers analyzed samples from the Sudbury Basin and found chondritic platinum group elements, which suggest a comet impact. The distribution of these elements indicates that the impactor was indeed a comet.
