Menopause, the beginning of aging for Chilean women: A qualitative study

Weaving a cocoon on the way to aging transcendence: Grounded theory study on aging perception during menopause transition

During menopause, women experience major changes, including the onset of aging as a natural and inevitable event. The present study aimed to explore and explain the process of aging perception during menopausal transition. This study was a qualitative grounded theory research, which was going to be implemented in 2019–2020 on 18 Baluch women settled in the Sistan & Baluchestan province in South-East Iran and among midlife or older menopause experienced women. Sampling was started first by Purposive sampling, and then it was performed with theoretic sampling. Data analysis was performed according to Corbin and Straus’s approach (2015) in four phases: (1) identifying and developing concepts; (2) analyzing data for the context; (3) entering the process stage into analysis; and (4) integrating categories to build a theory. In this study, seven main categories were obtained: “Sunset of youth”, “aging as the other side of the coin of menopause”, “Weaving a cocoon”, “aging as a mental trap”, “social acceptance”, “aging domino”, and “feeling of transcendence”. It seems that menopause plays an important role in Baluch women’s view toward aging. The practical results of this study can be applied to better understand the middle-aged and older Baluch women’s attitudes toward aging. Also study shows a new evolutionary and situational perspective on the lives of middle-aged menopausal Baluch women. Baluch women in menopause accept the sunset of youth and look forward to experiencing the Feeling of transcendence. Identify and respond to their needs by developing and establishing health policies to change their negative attitudes.

Loss of p27kip1 suppresses the myocardial senescence caused by estrogen deficiency

Estrogen deficiency accelerates the aging process and increases the risk of developing cardiovascular disease (CVD). Apoptosis is one of the important mechanisms of aging. p27^kip1 is a cyclin-dependent kinase inhibitor that can regulate cell cycle, apoptosis, and cell motility. p27^kip1 overexpression can inhibit cell cycle and increase apoptosis so it has been considered as a marker of aging. In the present study, bilateral ovariectomy (OVX) was performed as a model for menopause in wild-type (WT) and p27^kip1 knockout (KO) mice to assess the effects of p27^kip1 loss in myocardial aging caused by estrogen deficiency. We found that myocardial fibrosis and heart weight/body weight ratio of mice in the OVX group and p27^kip1 KO group were significantly increased. Echocardiography showed that the left ventricular diameter and volume of the WT OVX group increased significantly and the cardiac function decreased. However, there was no significant difference in the results of echocardiography between the two p27^kip1 KO groups. The aging and apoptosis indexes in OVX group were increased significantly, However, the indexes in p27^kip1 KO mice were decreased. The expression of antioxidant indexes in OVX group was decreased significantly and p27^kip1 KO can improve the antioxidant ability. These results provided that estrogen deficiency increased oxidative stress and apoptosis, accelerated aging of heart. p27^kip1 KO can partly delay the aging and apoptosis of heart through upregulated antioxidant enzymes.
