Fewer than 20% of US surgeons have high enough volume to optimize breast cancer outcomes, with median surgeon performing only 6 operations in two years. High-volume surgeons provide more consistent standard care, such as hormone receptor testing and breast conserving surgery.
Saint Louis University researchers discovered that the blood-brain barrier has a transport system for enzymes that is lost with aging. This discovery opens up new possibilities for treating lysosomal storage diseases by targeting the blood-brain barrier's delivery mechanism.
Researchers have created a smart window coating that reflects infrared light when temperatures rise above 29 degrees Celsius, reducing unwanted heat. This intelligent glass can help reduce energy consumption and provide cooler conditions for occupants.
The American Academy of Neurology has updated its diagnostic standard for headaches, adding new subtypes and disorders. The revised criteria provide a clearer framework for diagnosing and treating various types of primary and secondary headaches.
A recent study published in Cancer revealed that African-American women are four times more likely than white women to show significant alterations in the tumor suppressor gene p53. This finding suggests a greater burden of poor prognostic factors among African-American women, highlighting a potential link between genetic mutation and ...
Researchers at Stanford and Packard find that premature boys' brains are more severely affected than girls in areas responsible for reading, language, emotion, and behavior. The study reveals a significant disparity between preterm males and females, with preterm boys struggling more with speech and language.
The Eastern Interconnection Phasor Project provides real-time system-wide data to utilities and transmission operators, potentially preventing cascading loss of power. The project uses satellite-based time clocks and sophisticated signal processing to enable more accurate monitoring and analysis.
A study published in Archives of Internal Medicine found that 21% of elderly patients fill prescriptions for potentially inappropriate medications, with Amitriptyline and doxepin being common culprits. The researchers used a large national pharmaceutical benefit company's outpatient claims database to identify these inappropriate medic...
A computer simulation by Rice University scientists suggests that the ability to evolve can itself be favored through natural selection. This idea challenges traditional views and provides insights into the evolution of drug resistance in bacteria, immune system cells, and higher-order organisms.
A recent study by Michigan Medicine reveals that Mexican-Americans are twice as likely to experience a stroke or near-stroke compared to non-Hispanic whites. The disparity holds true across various age groups, including younger populations, with unique genetic predispositions and potential factors contributing to the increased risk.
Researchers found that disrupting the circadian clock gene led to abnormal estrous cycles and high rates of mid-gestation pregnancy failure. The study's findings have implications for human infertility, particularly for women working swing-shifts, who are more susceptible to irregular menstrual cycles and miscarriage.
A comprehensive study found that US Latinos have high rates of diabetic retinopathy, open-angle glaucoma, and cataract, with significant disparities in healthcare access. Researchers emphasize the importance of providing culturally tailored programs to detect and manage eye diseases in this population.
Research found that injured methamphetamine users stayed in hospitals longer and incurred higher costs, compared to those who tested negative. The study, which analyzed records of 212 patients, showed that positive test results were linked to increased hospital admissions, stays, and charges.
Researchers analyzed 15 years of data on liver transplant recipients with hepatitis B and found significant improvements in 5-year-survival rates from 53% to 76%. Advances in prophylaxis and treatment of recurrent HBV disease likely contributed to these gains.
A study by Duke University researchers found that over a year, one in five elderly Americans filled prescriptions for at least one 'drug of concern', including anti-depressants and anti-anxiety drugs with severe adverse effects. This highlights the need to improve education and screening of prescriptions to reduce risks.
Research suggests that mentally demanding jobs may protect against Alzheimer's disease by increasing brain cell activity and maintaining cognitive reserve. However, the exact link between job demands and Alzheimer's is not fully understood, and other factors such as socioeconomic status and environmental exposures may also play a role.
A team of scientists has identified an enzyme called CYP4AW1 that breaks down insect pheromones, allowing for the development of targeted treatments to prevent agricultural pests from breeding. By blocking this enzyme with a specific chemical, researchers may be able to disrupt the communication between insects and prevent infestations.
A new model shows that antibiotic cycling, alternating between classes of antibiotics every few months, probably won't work in stopping the spread of hospital-acquired antibiotic resistance. Instead, a mixing approach, where patients receive different antibiotics randomly, may be more effective in reducing resistance levels.
The study reveals alarming rates of eye diseases among Latinos, including open-angle glaucoma, diabetic retinopathy, and cataracts. These findings underscore the importance of developing tailored prevention and treatment strategies for this underserved population.
