The National Institute for Health and Clinical Excellence (NICE) proposes restricting use of ranibizumab and pegaptanib to patients who have gone blind in one eye. However, the Drug and Therapeutics Bulletin concludes that this approach is 'unacceptable' and calls for universal access to these sight-saving drugs. NICE has also not issu...
Researchers used time-lapse recordings to study IVF embryo development, finding that extended culture increases the likelihood of twinning. Blastocyst collapse may be caused by failed cell junctions, leading to degeneration and the formation of a second inner cell mass.
A new study by UCSF researchers suggests that pre-kindergarten tuberculosis skin testing is not a cost-effective way to spend healthcare dollars. The test would only be beneficial if at least 7% of children tested positive, which is now less than 1%. Instead, finding and treating adults with TB would be a more effective approach.

The study surveyed over 18,700 adolescents and their parents, revealing a significant association between socioeconomic status and migraine prevalence.
Women with endometriosis face a higher risk of certain cancers, including ovarian, kidney, and thyroid cancer. However, the risk is not affected by whether or not they have given birth. Conversely, women with endometriosis are less likely to develop cervical cancer.
A new study found that blacks with multiple sclerosis have significantly higher levels of an antibody in their spinal fluid than Caucasians, suggesting genetic factors contribute to the difference. The discovery may help explain why black patients are more likely to experience severe symptoms when they develop MS.
