The research provides insight into the dynamics of other host/disease systems and has implications for understanding diseases like AIDS.
A prospective cohort study found that regular exercise can benefit men with type 2 diabetes, while low physical fitness is associated with mortality. Meanwhile, a dangerous combination of blood thinners and intravenous steroids requires daily monitoring to prevent life-threatening bleeding.
A study conducted by researchers at Cincinnati Children's Hospital Medical Center shows that nearly 75 percent of children with severe juvenile rheumatoid arthritis respond dramatically to ENBREL (etanercept). The drug eases joint pain and swelling, enhances mobility, and improves disease activity for patients.
A recent study found that the genetic marker associated with periodontal disease in people of European heritage is barely present in Chinese populations. This suggests that oral hygiene habits, smoking, and other risk factors may be more important in explaining the high prevalence of periodontal disease in Chinese populations.
Global warming accelerates human disease outbreaks, malnutrition, and environmental degradation due to increased pollution and crop losses. As populations grow, crowded cities will become breeding grounds for diseases like dengue fever, while waterborne illnesses spread unchecked.
New research published in Gut journal found no evidence that measles virus is associated with Crohn's disease. The study isolated particles from the gut tissue of patients and compared them to healthy tissue samples, but found high levels of related cells in all types of samples.
A study published in the Journal of the American Academy of Dermatology found that severe psoriasis is debilitating, both physically and mentally, affecting quality of life for patients
Researchers have successfully reversed damage caused by Pompe disease, a rare inherited muscle-wasting disorder, in laboratory mice using a modified virus to deliver a therapeutic gene. The study's findings show promise for treating dozens of forms of muscular dystrophy and may lead to a continuous supply of enzyme production.
Recent findings in cystic fibrosis (CF) suggest that gene mutations can cause unexpected effects, leading to distinct conditions with clinical similarities to CF. Minor mutations may result in partial disease manifestations, challenging traditional notions of genetic screening and diagnosis.
The AVANT rotavirus vaccine demonstrated nearly 90% efficacy in preventing rotavirus disease in infants, surpassing existing vaccines' 49-68% efficacy rates. The vaccine was also found to be safe and immunogenic, with minimal side effects reported.
A recent study published in the Journal of Periodontology found that high financial stress and poor coping abilities significantly increase the risk of developing periodontal disease. Those who effectively manage their finances and cope with stress have no more risk than those without money problems.
Researchers have discovered a new form of ehrlichiosis caused by Ehrlichia ewingii, previously known to infect dogs, in humans in Missouri and other states. The disease can be fatal if left untreated, causing symptoms similar to the flu, and can lead to serious liver and lung problems.
A computerized system, developed by Purdue University engineers, matches patient CT scans with images in a large data base of previous patients' scans. This allows less-skilled medical personnel to aid in diagnoses by reducing the need for manual comparisons.
Researchers developed a new therapy using an enhanced artificial surfactant that improves oxygen levels and protects natural surfactant in lung-affected patients. The treatment has potential for treating infants and adults with difficult-to-treat lung disease cases.
Researchers at National Jewish Health found cases of chronic beryllium disease in two people exposed to 2 percent beryllium copper alloy, a product used in toasters, bicycles, and electronics. Chronic beryllium disease is caused by inhaling beryllium dust into the lungs, leading to lung scarring and oxygen transfer issues.
Researchers found a direct dose-response relationship between alcohol consumption and gum disease severity. Low antioxidant vitamins like selenium increased the risk of gum disease by 13-fold.
A new study by the NHLBI suggests that black patients with congestive heart failure are at a higher risk of death and disease progression compared to white patients. The study found significant racial differences in survival rates among patients treated with an ACE inhibitor.
A study found that spraying water with airborne bacteria in indoor swimming pools can lead to a lung disease called granulomatous pneumonitis. Lifeguards who worked long hours at pools with water features were most affected, and symptoms included cough, wheezing, and difficulty breathing.
Australian scientists have discovered key facts about the Hendra disease, a mysterious virus that infects horses, cats, guinea pigs, and fruit bats. Research shows the virus can be transmitted through contaminated food and cat urine, and is often deadly, even if not highly contagious.
A Cornell University study found that 40% of world deaths can be attributed to environmental factors. The study highlights the impact of organic and chemical pollutants, climate change, and emerging diseases on human health.
Scientists have created gene-altered mice that closely reproduce the clinical features of dilated cardiomyopathy, allowing for unprecedented study of early changes and development of new therapies. The model enables researchers to understand the causes and mechanism of the disease, ultimately aiming to develop more effective treatments.
Dr. Richard Facklam, CDC Lab Chief, receives award for his contributions to clinical microbiology research, focusing on streptococci identification and pneumococcal vaccine development. He has also worked on antimicrobial resistance studies in developing countries.
Thomas Jefferson researchers discovered that lower levels of the tumor suppressor gene Rb2/p130 correlate with increased risk of returning disease and higher mortality in women with endometrial cancer. The study suggests a potential diagnostic test to guide treatment and improve patient outcomes.
Researchers identified 20 modifiable risk factors contributing to mortality in older adults, including smoking, exercise, and chronic disease severity. Improved disease and health factors could lead to longer lifespan for those over 65.
Researchers at the University of Florida found that urban development in Florida is increasing the spread of Upper Respiratory Tract Disease among gopher tortoises. The disease destroys respiratory and olfactory senses, leading to malnutrition and starvation.
