Few studies have examined women's perspectives on their health and priorities in older age. In the current study, we administered a cross-sectional survey to women aged ≥60 years, recruited at a large community event in 2019. Participants ( = 303; mean age = 68 years) reported up to three 12-month life goals in open-text fields ( = 1,053 goals).

Background: Consumption of green tea has been associated with reduced risk of breast cancer. Hormonal modulation has been suggested as one of the potential underlying mechanisms; however, it has yet to be fully elucidated in large, long-term human clinical trials.

Objective: We investigated the effects of decaffeinated green tea extract (GTE) on circulating sex hormones and insulin-like growth factor (IGF) proteins.

Objectives: Fibromyalgia syndrome (FMS) is a chronically painful condition whose symptoms are widely reported to be exacerbated by stress. We hypothesized that female patients with FMS differ from pain-free female controls in their sympathetic responses, a fact that may unmask important biomarkers and factors that contribute to the etiology of FMS.

Materials And Methods: In a pilot study, blood pressure (BP), skin temperature, thermogenic activity, circulating glucose, and pain sensitivity of 13 individuals with FMS and 11 controls at room temperature (24°C) were compared with that after exposure to cold (19°C).

Background: Postmenopausal symptomatology has not been elucidated in large, long-term human clinical trials. Our objective was to measure quality of life in postmenopausal women aged 50-70 years.

Methods: A Menopause-Specific Quality of Life-Intervention (MENQOL) questionnaire was completed by women enrolled in the Minnesota Green Tea Trial (n=932) to assess vasomotor, physical, sexual, and psychosocial symptoms in the years following menopause.

Epidemiologic and animal studies suggest a protective role of green tea against breast cancer. However, the underlying mechanism is not understood. We conducted a randomized, double-blinded, placebo-controlled phase II clinical trial to investigate whether supplementation with green tea extract (GTE) modifies mammographic density (MD), as a potential mechanism, involving 1,075 healthy postmenopausal women.

Liver injury effects of green tea-based products have been reported in sporadic case reports. However, no study has examined systematically such adverse effects in an unbiased manner. We examined the potential effects of a high, sustained oral dose of green tea extract (GTE) on liver injury measures in a randomized, placebo-controlled, double-blinded phase II clinical trial, which enrolled 1,075 women with the original aim to assess the effect of daily GTE consumption for 12 months on biomarkers of breast cancer risk.

Context • Strontium ranelate is an approved prescription medication for the treatment of osteoporosis in Europe. In the United States, the only available forms of strontium are those that are nonprescription, dietary supplements. Some patients with osteoporosis use those products because they prefer an alternate treatment to conventional therapy.

Purpose: The Minnesota Green Tea Trial (MGTT) was a randomized, placebo-controlled, double-blinded trial investigating the effect of daily green tea extract consumption for 12 months on biomarkers of breast cancer risk.

Methods: Participants were healthy postmenopausal women at high risk of breast cancer due to dense breast tissue with differing catechol-O-methyltransferase (COMT) genotypes. The intervention was a green tea catechin extract containing 843.

Objective: Vitamin D deficiency and mood disorders are both prevalent among the elderly. We evaluated the association between vitamin D intake and mental health-related quality of life (QOL) among elderly women participating in a large population-based study.

Study Design: This study was a cross-sectional analysis of the Iowa Women's Health Study, a prospective study of cancer risk factors among post-menopausal women in Iowa that began in 1986.

Minnesota has played a leading role in the integrative holistic medicine movement in the United States for more than 2 decades. This article defines integrative holistic medicine and describes how it is practiced. It also discusses the reasons why institutions and providers here and elsewhere in the country have embraced this approach to patient care.

Reducing the dietary glycemic load and the glycemic index was proposed as a novel approach to weight reduction. A parallel-design, randomized 12-wk controlled feeding trial with a 24-wk follow-up phase was conducted to test the hypothesis that a hypocaloric diet designed to reduce the glycemic load and the glycemic index would result in greater sustained weight loss than other hypocaloric diets. Obese subjects (n = 29) were randomly assigned to 1 of 3 diets providing 3138 kJ less than estimated energy needs: high glycemic index (HGI), low glycemic index (LGI), or high fat (HF).
