Junrong Wu, Min Fang, Xiaoping Zhou, Bo Zhu, Zhi Yang
In this study, we explored associations between paraoxonase 1 (PON1) L55M and Q192R gene polymorphisms and the risk of breast cancer in 365 female breast cancer patients and 378 healthy controls from the Guangxi region of southern China. The LM heterozygous and MM homozygous genotypes, as well as M carrier status and M alleles, were associated with an increased risk of breast cancer. In addition, the M allele was associated with postmenopausal status and increased nodal involvement. In contrast, none of the Q192R genotypes or alleles were associated with a change in breast cancer risk, or with any of the clinicopathological parameters...

Post-menopause hyperandrogenism is a condition that needs careful evaluation. Aromatase inhibitors (AI), which are important in the management of positive estrogen breast cancer, and chronic kidney disease (CKD) can puzzle the evaluation of this condition. A postmenopause female with type-2 diabetes and advanced CKD was attended due to progressive virilization, which has started after the introduction of an AI for breast cancer 5 years earlier. Clinical and radiological investigation has confirmed a pure Leydig cell tumor as source of hyperandrogenism...

Perforative peritonitis is the most common surgical emergency in general surgical practice. Gastrointestinal perforation is the etiology in the vast majority of the patients. However, occasionally, other rare causes may be encountered. One such cause of peritonitis is spontaneous perforation of non-gravid uterus. Uterine perforation is a potential complication of any intrauterine procedure and may be associated with injury to surrounding blood vessels or viscera such as the urinary bladder or intestine. Spontaneous uterine perforation is rare and less than 50 cases have been reported in the English literature...

Obesity is a high risk factor for breast cancer. This relationship could be marked by a specific methylome. The current work was aimed to explore the impact of obesity and menopausal status on variation in breast cancer methylomes. Data from Infinium 450K array-based methylomes of 64 breast tumor were coupled with information on BMI and menopausal status. Additionally, DNA methylation results were validated in 18 non-tumor and 81 tumor breast samples. Breast tumors arising in either pre- or postmenopausal women stratified by BMI or menopausal status alone were not associated with a specific DNA methylation pattern...

Many clinical features of lung cancer are different in women and men. Sex steroid hormones exert effects in non-reproductive organs, such as the lungs. The association between menstrual and childbearing factors and the risk of lung cancer among women is still debated. We performed a pooled analysis of eight studies contributing to the International Lung Cancer Consortium (ILCCO; 4,386 cases and 4,177 controls). Pooled associations between menstrual or reproductive factors and lung cancer were estimated using multivariable unconditional logistic regression...

Among females who require the strategies for preventing osteoporosis, appropriate exercise and sport through all their life are important to increase or maintain bone mass. However, the type of exercise and sport applied to females is different in accordance with the lifecycle. Jumping exercise increases bone mineral content(BMC)in prepubescent children(premenarcheal girls). Bone mineral density(BMD)is higher in adolescent athletes who are engaged in weight-bearing activities. Jumping exercise, muscle strengthening exercise, and weight-bearing plus muscle strengthening exercises increase BMD in young adults and premenopausal women...

Postmenopausal osteoporosis is mainly caused by decreased estrogen levels, and progression of disease is associated with irreversible changes. It is therefore extremely important to maintain or improve healthy bone and calcium metabolism during and before the climacteric from a preventive medicine viewpoint. The specific preventive measures are appropriate calcium intake and regular physical exercise. In recent years, women in their twenties are considerably thinner and have a lower calcium intake than women in other age groups, which may lead to a further increase in the number of women with osteoporosis in the future...

Androgen as well as estrogen has physical, psychological and sexual roles in women. The action of androgen on bone health in women is important. The androgen receptor is expressed in osteoblasts and osteocytes but the mechanism has not been clarified in women. It has been reported that endogenous testosterone level was positively correlated with bone mineral density and higher testosterone level might be associated with decrease in bone fractures. Also, it has been reported that bone mineral density in women who received testosterone with estrogen was higher than that in women who received estrogen alone...

Osteoporosis, which patients are estimated as more than 13 million in Japan, is mainly caused by postmenopausal osteoporosis. Estrogen deficiency induced by menopause can disturb endocrine feedback and homeostasis, followed by bone loss by increased bone resorption with high bone turnover. Recent studies using systemic or conditional Estrogen Receptor α(ERα)gene knockout mice have unveiled molecular mechanisms underlying bone metabolism. In this review, it will be discussed that direct and indirect effects of estrogen and its metabolites for bone metabolism...

Development of bone metabolism markers began about 35 years ago. Current by the osteoporosis and bone metabolism diseases diagnosis and treatment efficacy. In childhood and adolescence, bone formation and resorption were increased, but formation rate was exceeded resorption rate. To keep strength of bone, bone formation and resorption are balanced(remodeling)in the period of maturity, Bone mineral density greatly decreases and biochemical markers of bone turnover markedly increase in postmenopausal women, indicating accelerated bone remodeling because of estrogen withdrawal...
