A new study suggests that a rapidly rising PSA level before treatment is a key indicator of cancer spread in men with clinically localized prostate cancer. The study found that men with a high PSA velocity (PSAV) are at greater risk of metastatic disease and should receive hormone therapy in addition to radiation.

The study found that men with aggressive locally advanced prostate cancer who received additional hormones lived longer, with a 31.9% increase in survival compared to those without further hormone therapy. The benefits also extended to men with less aggressive cancers, with improved disease-free and disease-specific survival rates.
A study found that longer-term hormone therapy does not extend survival for high-risk prostate cancer patients. Instead, it may lead to a lesser degree of treatment side effects and improved quality of life.
A new study by Joslin Diabetes Center has shown that with proper training and follow-up, over 80% of children and teens can successfully use insulin pumps to manage type 1 diabetes. The study identified key risk factors for failure, including infrequent blood glucose monitoring and high rates of severe hypoglycemia.
A study found that women with premenopausal breast cancer and 4+ positive lymph nodes may experience improved 10-year cancer-free survival with aromatase inhibitors. However, patients over 60 years old or those with advanced age, comorbidities, or fewer positive lymph nodes may not benefit from additional therapy.
A study by Oregon Health & Science University found that women on hormone therapy are more sensitive to negative events and can process emotions similarly to younger women. However, hormone therapy does not improve memory for negative events, suggesting that the brain's arousal system is modified with age.
A recent European survey of post-menopausal women with early breast cancer found that information needs are not being met, leading to low levels of patient involvement in treatment decisions. The survey revealed significant knowledge divides among patients, particularly older women and those with lower education levels.
A mathematic formula has been developed to predict a woman's risk of osteoporotic fracture, accurately identifying 75% of fractures two years after initial measurements were taken. The equation takes into account various risk factors beyond bone mineral density, allowing physicians to tailor treatment strategies to prevent fractures.

The therapy was effective in reversing stress-induced ovulation, offering a cost-effective and safe alternative to hormonal treatments.
A study by Vahakn B. Shahinian and colleagues found that urologist input significantly influences the use of hormone therapy for prostate cancer patients, with up to 21% of variance attributed to their decisions. This suggests that urologists can be targeted for interventions to modify treatment recommendations.
A new study suggests that cortisol levels alone may not be as useful for predicting the ability to quit smoking as the ratio of DHEA to cortisol. Research also found that oxytocin deficiency contributes to sweet tooth cravings, but not fatty snack preferences.
The accelerated decline in fertility over the past 2.8 million years is an evolutionary adaptation that helped humans survive. However, this shift has created challenges for modern society, particularly in regards to teenage pregnancy, delayed childbearing, and hormone replacement therapy.
A Stanford survey of 781 US women aged 40-60 found that nearly all reported experiencing menopausal symptoms, with many turning to herbal products and soy supplements instead of hormone therapy. Despite risks associated with hormone therapy, the study highlights the need for physicians to learn more about alternative therapies.
A study comparing Japanese American and white male patients who received hormone treatment for prostate cancer found that the former had a significantly higher five-year overall survival rate of 66% compared to 42%. The result was not affected by cancer stage or PSA levels, suggesting genetic and lifestyle factors may play a role.
Researchers have developed a new treatment protocol combining radionuclide therapy and chemotherapy that induces regression of prostate cancer in patients with metastatic disease. The combination regimen has been shown to alleviate bone pain and produce clinical benefit, including prolonged survival and reduced PSA levels.

Researchers found that chemotherapy improvements reduced recurrence risk by 21-55% in ER-negative tumors, while 9-26% in ER-positive tumors. This suggests that newer chemotherapies offer substantial benefits for patients with ER-negative disease.
Women taking estrogen had fewer breast cancer tumors, but the difference was not statistically significant. Participants also underwent more mammograms and biopsies, which may be related to changes in breast tissue.
A study analyzing data from the Women's Health Initiative found that postmenopausal hormone therapy may increase the risk of developing venous thromboembolism, particularly in women with higher physical activity levels and lower HDL cholesterol. The risk was significantly increased for deep vein thrombosis, but not for pulmonary embolism.

The research also identifies a possible molecular marker for predicting risk, which could inform growth hormone therapy for gastrointestinal conditions.
Researchers found a higher risk of developing lobular and tubular breast cancer in women taking HRT, with combined HRT increasing the risk even more. No increase in ductal breast cancer risk was observed, and some cancers were more hormone-receptive than others.
A recent study published by the Mayo Clinic found that MPA was more effective than venlafaxine in reducing hot flashes by 79% versus 55%. The single dose of MPA showed long-lasting benefits, with many patients still experiencing a 90% reduction in symptoms after six months.
Researchers found that a common osteoporosis treatment helped men with prostate cancer recover significant bone mass after two years of androgen deprivation therapy. The study suggests that bone density tests should be encouraged for men at risk, and bone-preserving therapy could prevent debilitating fractures.
Researchers found that administration of a bisphosphonate called zoledronic acid every three months significantly increased bone density in men with advanced prostate cancer. The study supports guidelines for monitoring bone density and initiating treatment to prevent fractures.
A new study found that androgen deprivation therapy is ineffective in preventing the spread of localized prostate cancer, despite its increasing use among men with non-spreading disease. Researchers suggest that men may endure significant side effects for uncertain benefits.
The study found a small but significant increase in hip bone density among women taking calcium combined with vitamin D. However, the supplements had no detectable effect on colorectal cancer incidence or spine fractures.

The research identifies a novel binding site on steroid receptors that makes them responsive to inflammatory signals.
A study of 93 critically ill patients found that hydrocortisone supplementation improved ventilator weaning success rates, especially in those with renal insufficiency. The treatment reduced mortality and morbidity in mechanically ventilated patients with adrenal insufficiency.
