Menopause-specific psychological symptoms, such as those measured by the Menopause Rating Scale, were found to have a strong association with turn...
A new study found that vaginal estrogen use is associated with a higher risk of perioperative UTIs in postmenopausal women experiencing hip fractures. Women with a history of recurrent UTIs were more likely to report perioperative vaginal estrogen use and experience a UTI.
A new study suggests that hormone therapy is associated with a greater migraine burden in postmenopausal women, with increased frequency and duration of migraine attacks, but no significant impact on symptom intensity or treatment needs. The study, which analyzed data from nearly 24,000 women, provides new insights into the relationshi...
A new study of over 1,800 women from 87 countries found that regular physical activity is associated with lower symptom burden in perimenopause, particularly psychological symptoms like low mood and anxiety. The study suggests that physical activity may be a low-risk strategy to improve overall well-being during the menopause transition.
Continuous transdermal nitroglycerin may reduce hot flash frequency in postmenopausal women who cannot use hormone therapy, with modest and inconsistent evidence. The treatment shows potential as a nonhormone option, but larger trials are needed to confirm its efficacy and safety.
A new gel material, inspired by sea cucumbers, has shown promising results in supporting tissue regeneration in preclinical studies. The gel acts as a temporary support structure that allows new tissue to grow, gradually breaking down and being absorbed by the body over several weeks.
Neurokinin receptor antagonists may affect molecular pathways involved in breast cancer growth and invasiveness, limiting cancer cell spread and preventing recurrence. Laboratory and tissue-based studies found NKB receptors over-expressed in cancerous breast tissue, reducing cancer cell viability and downregulating oncogenic pathways.
A new study presents an AI-enhanced virtual reality program, MenoZen VRTM, that effectively delivers cognitive behavioral therapy to manage menopause symptoms. The program addresses access barriers to traditional therapies, providing a personalized and convenient solution for midlife women.
Researchers at Nagoya University have discovered a new defense mechanism in neurons to prevent TDP-43 protein aggregation, a major cause of ALS. By activating the immunoproteasome, neurons break down TDP-43, reducing aggregation and motor neuron damage.
