Filter by:The aim of this observational study was to investigate the effect of the menstrual cycle on the manual dexterity of female dentists. This study was conducted to answer the following question: - Is there any effect of the menstrual cycle on the manual dexterity of female dentists?
The study was designed as an observational study
The influence of the menstrual cycle on women's sports performance is still uncertain. Research on this topic shows methodological biases. The aim of the study will be to determine whether the menstrual cycle affects women's physical fitness, measuring this in 3 differentiated stages of the cycle: the early follicular phase, late follicular phase, and luteal phase. For this purpose, a blood test will be carried out in each phase, with hormone determination (oestradiol and progesterone) and a haemogram to determine the existence of possible anemia. After the extraction and other complementary tests (measurement of vital signs, bioimpedance...) the woman will undergo 3 physical tests to compare the results in the 3 phases. A group of women taking hormonal contraception will also be included, performing the same interventions. To determine whether the woman is ovulating or not, urinary luteinizing hormone (LH) strips will be given to the women and they will have to take them from day 8 of the cycle. In addition, women will wear an accelerometer to monitor their daily activity and to be able to observe if there is an influence on this stage of the menstrual cycle.
The aim of this study was to investigation of knee position sense, balance, and dual task performance in different phases of menstrual cycle in females with multiple sclerosis. Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) affecting young people and leading to demyelination and neurodegeneration. MS affects females more than males with a ratio approximately of 3:1. Important gender differences in progression and inflammatory activity of disease have been observed. Sex hormones have been thought to play an important role in this condition. It is worth noting however that sex hormones not only affect reproduction (menses/pregnancy), they also have direct effects on the nervous and immune system. In the neurologic group, especially in MS patients, it is well known that disease activity, course, and symptoms can be influenced by hormonal fluctuations in different phases of the menstrual cycle. Previous studies have reported that the variation of estrogen and progesterone during the menstrual cycle may have an effect on several neurological functions. However, these studies are mostly subjective, in the form of patient reports and in limited numbers. Smith and Studd reported that there was a premenstrual increase in disease severity as changes in the Th-1 / Th-2 balance occurred in association with decreased circulating estrogen. Withdrawal of hormones from damaged tissues that affect axonal conduction can explain the change in disease activity, course symptoms during the menstrual cycle in female with MS. For all these reasons,investigators think that different phases of menstrual cycle change position sense, balance, and dual task performance in females with MS. Considering hormonal fluctuations occurring in the menstrual cycle, is an important criterion for organizing the rehabilitation program and evaluation in terms of physiotherapy.
Quitlines are efficient and cost-effective treatments for smoking cessation, yet little research has explored how to personalize and optimize quitline services for women. The goal of this project is to explore the feasibility and preliminary efficacy of a quitline intervention that considers the menstrual cycle as compared to standard care for cessation. If funded, the results of this study will directly inform future research on quitline smoking cessation interventions for premenopausal women, including a full scale clinical trial.
The aim of this study was to investigate the effects of menstrual cycle phases on recovery and cognitive function after general anesthesia.
The investigators aimed to investigate the effect of menstrual cycle phases on preoperative anxiety in women under general anesthesia.
The overall goal of this study is to examine the influence of the menstrual cycle on micronutrient concentrations and plasma volume in healthy, reproductive-age women with regular cycles. The investigators aim to quantify changes in micronutrient biomarker concentrations (zinc, copper, iron, and vitamin A) and plasma volume across the menstrual cycle in healthy women.
This study aims to use validated tools as well as new technology to examine changes in bleeding patterns among women who are initiating the copper T380A IUD.
The purpose of this study is to investigate whether sleep disruption affects menstrual cycle timing
