OBJECTIVE To compare induced surgical menopause in rat models following hysterectomy with ovarian preservation, unilateral or bilateral oophorectomy, versus control. Secondary objective was evaluation of certain physiological changes in the animal following the induced menopause. DESIGN A prospective case control study. SETTING University Research Centre. METHODOLOGY 80 female rats were d...
Age at menopause has implications for fertility and risk of hormonally related chronic diseases. Some pesticides disrupt reproductive hormones or are toxic to the ovary, but little is known about the association between pesticide exposure and timing of menopause. Cox proportional hazards modeling was used to examine the association between use of pesticides and age at menopause among 8,038 wome...
Differentiated thyroid carcinoma (TC) is threefold more common in women than in men and, therefore, a role of female hormones in the etiology of differentiated TC has been suggested. We assessed these hypotheses in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Among 345,157 women (mean age 51) followed for an average of 11 years, 508 differentiated TC cases wer...
Evidence suggests a role for reproductive and hormonal factors in the etiology of colorectal cancer. Investigation of adenomas, the presumed precursors of cancer, and reproductive characteristics may place such associations within a particular stage of carcinogenesis. We examined parity, age at first birth, age at menopause, and age at menarche as well as contraceptive and noncontraceptive horm...
OBJECTIVE Motivated by inconsistent literature, we evaluated the association between incident pancreatic cancer and reproductive characteristics. DESIGN The Iowa Women's Health Study is a large prospective population-based cohort followed from 1986 to 2003. Reproductive information was self-reported. PARTICIPANTS The study population comprised 37,459 women aged 55-69 years at baseline. Over...
Background Surgical early menopause is due to medical reasons rather than the natural aging process. Pulse wave velocity (PWV) and augmentation index (AIx) are simple non-invasive parameters for assessment of arterial stiffness. The aim this study investigated stiffness in surgical patients. Material Method We included 40 patients with healthy controls study. patients’ hemodynamic were measured...
Risk-reducing bilateral salpingo-oophorectomy is a proven strategy to reduce the risk of serous ovarian cancer associated with germline BRCA mutations. It is most effective when performed before natural menopause, but it will render a woman prematurely menopausal. The tubal hypothesis of serous ovarian cancer brings with it the possibility of the alternative surgical approach in younger women c...
Background When considering the "joint as an organ", the tissues in a joint act as complementary components of an organ, and the "set point" is the cellular activity for homeostasis of the joint tissues. Even in the absence of injury, joint tissues have adaptive responses to processes, like aging and menopause, which result in changes to the set point. Purpose The purpose of this study in a p...
