(Press-News.org) CLEVELAND, Ohio (Sept 27, 2023)—Dual energy x-ray absorptiometry (DXA) is the gold standard for assessing bone mass and evaluating fracture risk. But new technologies shed light on knowledge gaps not filled by DXA alone and sometimes suggest the need for additional procedures to accurately assess bone health. A presentation at the 2023 Annual Meeting of The Menopause Society in Philadelphia September 27-30 will focus on the evolution of technology to better diagnose bone fragility.
The discussion of bone health is especially relevant for postmenopausal women who are more vulnerable to osteoporosis and osteopenia because of declining estrogen levels that occur during the menopause transition. Measurement of bone mineral density by DXA is the predominant means for identifying if a woman is predisposed to fragility fractures. That’s because the majority of the bone’s strength, 60-75%, is accounted for by bone mass.
But bone mass alone doesn’t tell the entire story as to the strength of a woman’s bones and her risk for fractures. At the 2023 Annual Meeting of The Menopause Society, Dr. Marcella Walker from Columbia University’s Division of Endocrinology will lead a discussion focused on newer non- or minimally invasive technologies that are yielding additional information beyond bone mineral density to provide a fuller picture of a patient’s overall bone health.
Assessment advances include the trabecular bone score (TBS), which is an indirect measure of spine trabecular microarchitecture obtained from the DXA image to predict fracture risk independently of, but in conjunction with, BMD. Vertebral fracture assessment (VFA), also performed on a densitometer, can detect vertebral fractures, many of which go undetected. In just the past two years, the FDA also approved impact microindentation (IMI), which measures the distance a probe extends into the tibial bone cortex, thereby effectively measuring bone material strength. It correlates with the bone’s ability to resist the development of cracks and is performed using a minimally invasive, hand-held device.
According to Dr. Walker, there is so much exciting technology becoming available that can tell us a lot about a bone’s strength. While she believes there is tremendous value in utilizing several measurements of bone quality in some patients, she cautions that many women are not receiving the minimal screening for osteoporosis with bone mineral density measurement by DXA.
“It is important for both clinicians and patients to understand that osteoporosis doesn’t cause any symptoms until a fracture occurs. That is why it is so essential for women at risk to have bone mineral density measured by DXA. Adjunctive technologies, such as TBS and VFA, are particularly helpful to further risk stratify women close to the therapeutic intervention threshold where this information might change a decision to start treatment,” says Dr. Walker.
“This presentation should provide valuable insights about the various technologies available to healthcare professionals in order to get a more accurate picture of their patients’ risk for fracture” says Dr. Stephanie Faubion, medical director for The Menopause Society. “Bone health and avoiding fractures is such an important issue for women at midlife.”
Drs. Walker and Faubion are available for interviews before and after the presentation at the Annual Meeting.

Hot flashes yet another early indicator for Alzheimer's disease
2023-09-27
CLEVELAND, Ohio (Sept 27, 2023)—As if hot flashes alone weren’t bad enough for women going through the menopause transition, a new study suggests that, especially when they occur during sleep, hot flashes may be early indicators of a woman’s increased risk for Alzheimer’s disease (AD). And, the more hot flashes, the greater the disease risk. Study results will be presented during the 2023 Annual Meeting of The Menopause Society in Philadelphia September 27-30.
Women comprise two-thirds of individuals with AD, and there are ...
Post-traumatic stress symptoms can cause problems in the bedroom for midlife women
2023-09-27
CLEVELAND, Ohio (Sept 27, 2023)—Post-traumatic stress disorder (PTSD) has been associated with a number of adverse mental and physical health outcomes. Little is known, however, regarding its impact on sexual functioning among midlife women. A new study is shedding light on the topic, suggesting that greater PTSD symptoms lead to worse sexual functioning. Study results will be presented during the 2023 Annual Meeting of The Menopause Society in Philadelphia, September 27-30.
PTSD is more common among women than many ...
The effects of sexual orientation on sexual function and distress
2023-09-27
CLEVELAND, Ohio (Sept 27, 2023)—In recent years, there has been debate around the topic of who is happier, healthier, and more satisfied sexually—traditional heterosexual or sexual minority women. A new study suggests that cisgender heterosexual women have higher relationship scores and less anxiety and depression than their less traditional counterparts. Study results will be presented during the 2023 Annual Meeting of The Menopause Society in Philadelphia September 27-30.
Satisfaction with one’s relationship and sex life has been shown to ...
Hot flashes linked with risk factors for cardiovascular disease

What your hair and saliva say about your risk for depression and cognitive shortfalls during menopause
2023-09-27
CLEVELAND, Ohio (Sept 27, 2023)—Stress affects the body and brain in many ways by causing the endocrine system to increase cortisol levels. These spiked levels can be found throughout the body. A new study suggests that elevated cortisol levels in the hair and saliva may affect cognitive and mental health in late peri/early postmenopausal women. Study results will be presented during the 2023 Annual Meeting of The Menopause Society in Philadelphia September 27-30.
It’s no secret that stress can take a major toll on the body and ...
Obese women have worse menopause symptoms nd get less relief from hormone therapy
2023-09-27
CLEVELAND, Ohio (Sept 27, 2023)—Obesity has already been associated with a number of adverse health conditions and can interfere with a person’s quality of life. A new study suggests that, in addition to these other problems, it may also worsen a woman’s menopause symptoms and limit the amount of relief she gets from hormone therapy (HT). Study results will be presented during the 2023 Annual Meeting of The Menopause Society in Philadelphia, September 27-30.
HT remains the most effective ...
New research identifies genetic links between schizophrenia and cardiovascular disease risk factors
2023-09-27
WASHINGTON, D.C., Sept. 27, 2023 — New research finds that people with schizophrenia have a genetic propensity to smoking and a reduced genetic risk of obesity. The study, published in The American Journal of Psychiatry, revealed genetic overlap between schizophrenia and cardiovascular disease (CVD) risk factors, particularly body mass index (BMI) and smoking. The findings highlight the importance of environmental factors in the development of obesity and other CVD comorbidities.

Workshop synthesis paper describes value of prescribed fire in wilderness areas
2023-09-27
GUNNISON, Colorado, September 18, 2023 - Many of the wilderness areas that we treasure were historically shaped by fire. Yet today, many wilderness landscapes are caught in the wildfire paradox – widespread suppression and exclusion of burning over the last century have increased the likelihood of high-intensity fires, which are more damaging rather than restorative. In December of 2022, experts from land management agencies, Tribes, and organizations across the country convened at the Wilderness and Fire Workshop in Gunnison to consider solutions to this dilemma, including the use of prescribed fire. Today, ...
Patients who quit smoking after percutaneous coronary intervention do as well as non-smokers – unless they had smoked heavily
2023-09-27
Patients who quit smoking after undergoing percutaneous coronary intervention (PCI) for narrowed arteries have similar outcomes as non-smokers during four years of follow-up after the procedure, according to a large study published in the European Heart Journal [1] today (Wednesday). However, if they had been heavy, long-term smokers, no improvement was seen.
The study of 74,471 patients who had a PCI between 2009 and 2016 is the first, large population-based study to examine the impact of smoking on cardiovascular outcomes, such as death, heart ...
