A study found that melanomas can appear noticeably different from other moles, with 85% of participants identifying them as distinct. The 'ugly duckling' sign may prove a useful screening strategy for primary health care providers and skin self-examination.
Researchers from the University of Wisconsin-Madison have developed a system to genetically disarm the Ebola virus by removing its VP30 gene. This allows for safe study of the pathogen in specialized cells, enabling the development of countermeasures such as vaccines and antiviral compounds.
A new imaging study of 3000 people found that women's skulls are thicker and more resistant to injury than men's, with average thicknesses of 7.1mm for females compared to 6.5mm for males.
A new classification system of 15 lip zones can help cosmetic surgeons better control lip shape and size, leading to high patient satisfaction and no adverse effects. The study involved 137 treatments on 66 patients and found an average score of 4.5 for patient satisfaction.
Researchers analyzed data from the National Cancer Institute's Prostate Cancer Prevention Trial, showing that finasteride reduces prostate cancer risk by 25% but also causes side effects like impotence. The study encourages men to consider both benefits and drawbacks before taking the drug to prevent prostate cancer.
A study found surgical site infections in 5.3% of patients following breast surgery, with higher costs and longer hospital stays for infected patients. The cost of surgical site infections was estimated at $4,091 per patient.
Anti-TNF compounds disrupt germinal centers, training grounds for immune cells in autoimmune diseases like rheumatoid arthritis and lupus. The team found that these drugs eliminate abnormal B cell activity, raising the possibility of improved patient health.
A team of LA BioMed researchers developed a new, more reliable method for measuring protein synthesis and turnover using deuterated water and mass spectrometry. This breakthrough enables scientists to study the dynamics of every protein in the human body accurately for the first time.
The pharmaceutical industry is failing pregnant women due to a lack of drug development for maternal health, with only 17 drugs in active development. This 'drug drought' is attributed to the high litigation costs associated with testing and developing drugs during pregnancy.
A new study assesses the ecological costs of human activities on a global scale, finding that rich nations' environmental footprints heavily impact poor countries. The study estimates that the portion of high-income nations' footprints falling on low-income countries is greater than their combined financial debt.
A saline nasal wash solution improved nasal symptoms and reduced the recurrence of respiratory infections in children with the common cold. Children using the saline group had fewer days of illness, missed school days, or complications compared to those receiving standard medication.
A systematic review found sorafenib significantly increases the risk of developing hypertension, particularly high-grade hypertension. Patients receiving sorafenib require close monitoring and effective management to prevent cardiovascular complications.
Researchers at Mount Sinai School of Medicine have discovered a novel targeted gene therapy that simulates the pain-killing effect of opiate drugs, providing relief for more than three months after a single injection. The technique targets selectively the pain gate, avoiding unwanted side effects associated with opioid painkillers.
Researchers are conducting a US trial using purified adult stem cells to treat critical limb ischemia, a condition that affects 1.4 million people and can lead to amputation. The study aims to grow new blood vessels and restore circulation in legs with severely blocked arteries.
A Kaiser Permanente study found that high doses of caffeine daily during pregnancy increase the risk of miscarriage, particularly among women consuming coffee, tea, and hot chocolate. Women who consumed over 200mg of caffeine per day had twice the miscarriage risk compared to those with no caffeine intake.
A recent study by Beth Israel Deaconess Medical Center found that the majority of adverse events and device malfunctions associated with biliary stents occur during off-label use. Over 1 million patients received these devices for 'off-label' treatments between 2003 and 2006.
Researchers propose a new pricing plan where consumers pay an annual fee for medication access, potentially increasing patient compliance and reducing long-term health problems. The system could reduce periods of medication skipping due to cost, benefiting patients with chronic conditions such as high cholesterol, diabetes, or asthma.
A study found that trauma centers upgraded to Level 1 designation had lower death rates compared to those designated as Level 2. Severely injured patients admitted to Level 1 centers had significantly reduced mortality rates, suggesting improved protocols and care may be key to saving lives.
Researchers have identified 75 genes involved in silica bioprocessing in diatoms, which could lead to more efficient and smaller-scale nanofabrication for computer chips. The discovery could increase chip speed and address the current limitation of photolithographic techniques.
Researchers find a direct link between visceral fat and atherosclerosis, a condition that causes blood vessels to harden and narrow. The study suggests that anti-inflammatory medication could be used to reverse the process and reduce heart disease risk.
Researchers developed a mathematical model to explain infection patterns of Schistosoma japonicum. They found that transmission from snails to mammals was the primary factor in explaining differences among villages. Interventions targeting snail populations may be more effective than others, according to the study.
Recent studies from NIH scientists resolve debate about CA-MRSA molecular evolution, revealing a single strain USA300 as the primary cause of community-associated methicillin-resistant Staphylococcus aureus infections. The research also sheds light on how MRSA evades the human immune system and spreads rapidly.
Researchers at ETH Zurich have identified two subtypes of GABA receptors that mediate spinal pain control, opening up new possibilities for targeted pain therapy. This discovery could lead to the development of specific drugs with fewer side effects, making chronic pain treatment more effective.
Research from the University of Bristol shows that osteopontin is a key gene in scarring, and suppressing its activity can speed up wound healing and reduce scarring. The study's findings have major implications for treating wounds, organ tissue damage, and fibrosis.
