A study of 13,958 Canadian women found that the median time from screening to first assessment was 2.6 weeks and to diagnosis was 3.7 weeks. Women with breast cancer waited shorter times than those with benign findings. However, even with expedited investigations, 10% of women with breast cancer still waited over 12 weeks for a diagnosis.
Scientists have discovered a natural method to track Atlantic salmon using strontium isotopes, which can reveal the fish's origin and migration patterns. This discovery could provide valuable insights into salmon habitat restoration efforts and inform more effective conservation strategies.
Researchers find that human population growth is slowing due to increased birth rates being offset by negative feedback from crowding and resource depletion. The world population is expected to reach 10-12 billion around 2100, despite a near doubling in numbers.
A large study has established a connection between being overweight and earlier-than-average puberty in white girls, but found a weaker link in black girls. Researchers suggest that genetic or environmental factors may be at play in the latter group.
Researchers are using new technology to measure coastal erosion in the UK, with a focus on the North Yorkshire coastline. They are creating highly accurate 3D computer models that detail when and where erosion is most likely to occur.
A study by University of Michigan doctoral student Miroslav Kummel found that plants associate with different fungi depending on light conditions, suggesting a choice-based mechanism for nutrient exchange. This discovery could have implications for the timber industry and our understanding of plant-fungus interactions.
Researchers at PNNL and the US Army Corps of Engineers used an acoustic camera to study fish behavior near a dam, capturing images of individual fish at distances of up to 30 feet. The camera provided detailed information on fish size and shape estimates, expanding understanding of how fish react to structures added to dams.
A novel vaccine has been developed to protect against Leishmaniasis, a disease caused by the single-celled parasite Leishmania. The vaccine targets a component of sand fly saliva, dubbed SP15, which appears to induce natural immune responses in mice.
Parents of children with chronic conditions are less likely to enroll in gatekeeping HMO plans, which are designed to improve care coordination. The study found that after switching to an HMO, kids with chronic illness had fewer visits to specialists and primary care physicians.
A recent Canadian Medical Association Journal study found that 88.5% of patients admitted to hospital with congestive heart failure underwent left ventricular testing, but only 23% received target doses of ACE inhibitors as prescribed in clinical trials. This underdosing rate is lower than previously reported rates in Europe and the US.
Research by Ricardo Carvajal at University of Michigan found a decline in epiphytes on coffee farms with intensive practices. However, even in most intensive plots, 'reservoirs' where epiphytes thrive were discovered, suggesting potential for conservation through targeted planting.
Researchers found that encasing pillows and mattresses with allergen-proof covers, washing bedding weekly, and vacuuming carpets reduced dust mite allergen concentrations. Dry steam cleaning also lowered allergen levels in upholstered furniture.
The Annals series examines complementary and alternative medicine (CAM), classifying hundreds of therapies into a new taxonomy. CAM modalities like herbs, acupuncture, and homeopathy are studied, as well as the social context and effectiveness of these practices.
In a breakthrough study, researchers at The Wistar Institute demonstrated the remarkable regenerative powers of MRL mice in healing heart tissue without drugs or cell transfer. After two months, damaged heart tissue looked normal and functioned well.
A four-year interdisciplinary study has identified young faults at the Oracle site and pinpointed the emissions responsible for the Pythia's trance state as light hydrocarbon gases from bituminous limestone. The study also found ethane, methane, and ethylene in spring water near the Oracle.
Vancouver is facing a high risk of an hepatitis A outbreak due to past infections among street youth, injection drug users, and men who have sex with men. The Canadian Medical Association Journal report highlights the need for vaccination programs to protect these groups.
A population-based study found that the annual rate of potential brain injury was 16 per 10,000 among males and 7 per 10,000 among females. The leading causes of brain injury varied by age, with falls from heights being common among young children and accidents involving motor vehicles or bicycles being common among older teenagers.
The journal launches a series on complementary and alternative medicine (CAM), classifying over 200 therapies into eight categories. ACP-ASIM opposes the legalization of physician-assisted suicide, citing concerns about inadequate care at end-of-life.
The American College of Physicians-American Society of Internal Medicine opposes physician-assisted suicide, considering it a threat to the patient-physician relationship. Instead, they suggest improving access to hospice care, palliative care, and pain management.
Researchers discovered strontium titanate deforms plastically at low stresses and temperatures, contrary to its brittle nature. Detailed analysis reveals the existence of different dislocation core structures, suggesting potential applications in forming or enhancing ceramic properties.
