Researchers from the Harvard School of Public Health (HSPH) found consistent evidence that smoking is associated with an increased risk of TB. They also found that passive smoking (secondhand smoke) and the burning of biomass fuels was associated with an increased TB risk.
Results of a recent study linking low LDL cholesterol to Parkinson’s provide the strongest evidence to date that it could be real, because statins work by reducing LDL cholesterol. The study by researchers at University of North Carolina showed that patients with low levels of LDL cholesterol are more than three and a half times more likely to develop Parkinson’s disease than those with higher LDL levels.
Being a member of a large family may not be best for your health. A new study found that family size greatly influenced the development of stomach cancer linked to the bacterium Helicobacter pylori, and younger siblings from large families appeared to be especially vulnerable to the most common type of stomach cancer.
Benzodiazepine use was not shown to be associated with hip fractures after all, according to a new study from the Department of Ambulatory Care and Prevention (of Harvard Medical School and Harvard Pilgrim Health Care). Previous epidemiological studies suggesting an association have been used to support legislation and policy decisions that limit access to these drugs among the elderly. These policies may need to be reexamined based on these new findings, which are being published in the Jan. 16 Annals of Internal Medicine.
A new study has found a drop in the number of patients undergoing the most commonly used stroke prevention surgery, carotid endarterectomy, for inappropriate reasons. Researchers are crediting the drop to highly publicized randomized controlled trials (RCTs) that clarified the appropriate use of the surgery. The researchers’ findings are published in the January 16, 2007, issue of Neurology?, the scientific journal of the American Academy of Neurology.
University of Minnesota stem cell researchers, together with collaborators at Stanford University, have successfully used adult stem cells to replace the immune system and bone marrow of mice, offering the promise of new therapies for people in the future.
A new University of Illinois study shows that tomatoes and broccoli — two vegetables known for their cancer-fighting qualities — are better at shrinking prostate tumors when both are part of the daily diet than when they’re eaten alone.
Researchers have linked a structural protein called nestin to a particularly deadly form of breast cancer, identifying a new biomarker that could lead to earlier detection and better treatment.
Combination gene therapy delivered in lipid-based nanoparticles drastically reduces the number and size of human non-small cell lung cancer tumors in mice, researchers at The University of Texas M. D. Anderson Cancer Center and the University of Texas Southwestern Medical Center report in the January 15 edition of Cancer Research.
For the most part, dementia and delirium have been viewed as separate and distinct conditions. But a special section of the Journal of Gerontology: Medical Sciences, appearing in January 2007, looks at their interface, asking: Can delirium itself lead to the development of a cognitive disorder? Do delirium and dementia represent opposite ends of the same spectrum of disease, rather than two separate conditions?
