Alzheimer's Linked to Thyroid-Related Hormone

SOURCE: MedPage Today

DATE: July 28, 2008

EXCERPT: "Abnormal levels of the hormone thyrotropin, which controls thyroid function, may be associated with an increased risk of Alzheimer's disease in women, researchers found.  Alzheimer's disease was more than twice as common among women with the highest and lowest levels of serum thyrotropin compared with those in the more normal range (P<0.001 and P=0.003, respectively), ....  However, the associations did not extend to men for either high or low levels of the hormone in the analysis of the longitudinal Framingham Study.    more

Genes could explain memory differences between men and women

SOURCE: Telegraph.co.uk

DATE:  July 20, 2008

EXCERPT:  "Researchers at the Institute of Psychiatry, King's College London, have found that males use different genes from females when making the new connections in the brain that are needed to create long-term memories. They believe this might explain why men are far better at remembering "tactical" memories, such as travel directions and trivia, while women form more "emotional" memories such as birthdays, wedding anniversaries and details about the world around them."   more

Nutritional Requirements By Gender

SOURCE:  Medical News Today

DATE:  July 17, 2008

EXCERPT: "In the first study of its kind, the researchers have shown that gender plays a major role in determining which diet is better suited to promoting longer life or better reproductive success."   more

Rose-Colored Glasses Lessen Cardiovascular Mortality in Men

SOURCE: medpageTODAY.com

DATE: July 16, 2008

EXCERPT: "Men who view themselves as essentially heart healthy are more likely to be so than others who fret over a perceived precarious cardiovascular status.  Those who rated their risk as lower than average were 60% less likely to die within 15 years than those who thought they had an average or elevated risk, even after controlling for actual cardiovascular risk (HR 0.4, 95% CI 0.2 to 0.8), Robert Gramling, M.D., D.Sc., of the University of Rochester, and colleagues reported in the July/August issue of the Annals of Family Medicine.  Optimistic women, on the other hand, had no such reduced mortality risk (HR 1.5, 95% CI 0.8 to 2.8)."    more

Gender Differences Studied In Risk Of Diseases Caused By Blood Clots

SOURCE:  Medical News Today

DATE:  July 12, 2008

EXCERPT: "Being male increases your risk of diseases caused by the inappropriate formation of a blood clot (a process known as thrombosis), such as heart attack and stroke, but the reasons for this are not completely understood. However, Ethan Weiss and colleagues at the University of California, San Francisco, have used a mouse model of thrombosis to shed new light on this matter."  more

Men And Women Benefit From Gender Specific Kidney Transplants

SOURCE:  Medical News Today

DATE:  July 10, 2008

EXCERPT:  "The gender of donor and recipient plays a larger role in kidney transplants than previously assumed. Female donor kidneys do not function as well in men - due to their smaller size. Women have a higher risk of rejecting a male donor kidney. Therefore, in the future, gender should be considered more in the allocation of donor kidneys, say researchers from Basel and Heidelberg."  more

Men And Women With History Of Concussion Mend Differently, Study Finds - Concussion Treatment Needs To Be More Individualized

SOURCE: Medical News Today

DATE:  July 10, 2008

EXCERPT: "Female soccer players and soccer players who have had a previous concussion recuperate differently from males or players without a history of concussion  .....   The study found that prior history of concussion and gender account for significant differences in test results following the injury. Because of these differences, the authors urge physicians and coaches to take an individualized approach to treating concussion patients."   more

Response To Vaccination Affected By Gender, Time Of Day

EXCERPT: "A new study in the journal Psychophysiology reveals that men, but not women, vaccinated in the morning produced a better peak antibody response to both hepatitis A and the influenza strain." more

Female Kidney Transplant Recipients Are More Likely To Reject Male Donor Organs

SOURCE:  Medical News Today

DATE:  July 5, 2008

EXCERPT: "New research published in The Lancet suggests that sex-matching kidney donors and recipients may result in better outcomes. The report finds that when females receive a male donor kidney, they have higher rates of graft failure compared to the other three combinations of donor and recipient. These findings imply that future studies and decisions about organ donations should take sex into consideration."   more
