Filter by:Recruit postmenopausal women and randomly assign them to one of four groups: Early Postmenopausal Exercise Group (EE), Late Postmenopausal Exercise Group (LE), Early Postmenopausal Control Group (EC), and Late Postmenopausal Control Group (LC). All participates will undergo a graded exercise test to determine their maximum oxygen uptake, and vascular function response will be measured immediately after the exercise test. The COP exercise intensity for postmenopausal women will be obtained through the exercise test, and subjects in the EE and LE groups will undergo exercise training at this intensity for a period of three months. Tests and analyses of relevant indicators will be conducted on subjects in all four groups before and after the intervention. The exercise load experiments will be performed on a cycle ergometer.
GraviD is a multi-ethnic population-based pregnancy cohort. Pregnant women were invited to participate in the GraviD study when registering for antenatal care in parts of the region of Västra Götaland in Sweden in 2013-2014. All women registering for antenatal care were eligible for inclusion, as long as the pregnancy had not exceeded 16 gestational weeks. In total, 2125 pregnant women were recruited in gestational week 12 during two time-periods; fall 2013 and spring 2014. Blood sampling was performed in gestational week <17 and again at gestational week >31 by midwifes. After delivery, the maternity records were obtained, to collect information on child's gender, birth weight and length and other possible birth outcomes.
Cerebral small vessel disease is a frequent cause of cognitive disability among older adults (OAs) in Mexico that imposes a significant burden on the health system and OAs' families. We have called the program Mind and Movement for Cognitive Health (MeMo-Salud-Cog-3). Programs to prevent or delay OAs' cognitive decline are scarce. Methods and analysis: A double-blind, randomized clinical trial will be conducted. The study will aim to evaluate two 24-week double-task (aerobic and cognitive) square-stepping exercise programs for OAs at risk of cognitive decline-one program with and another without caregiver participation-and to compare these with an aerobic-balance-stretching exercise program (control group). 255 OAs (85 per group) affiliated with the Mexican Institute of Social Security (IMSS) between 60 and 65 years of age with self-reported cognitive concerns will participate. They will be stratified by education level and randomly allocated to the groups. The intervention will last 24 weeks, and the effect of each program will be evaluated 12, 24, and 52 weeks after the intervention. Participants' demographic and clinical characteristics will be collected at baseline. The outcomes will include: (i) general cognitive function; (ii) specific cognitive functions; (iii) dual-task gait; (iv) blood pressure; (v) carotid intima-media thickness; (vi) carotid arterial compliance; (vii) OAs' health-related quality of life; and (viii) caregiver burden. We will estimate differences in outcomes between each intervention group and the control group at baseline and follow-up evaluations. We will assess differences-in-differences (D-in-D) treatment effects using a D-in-D estimator. If we identify statistically significant differences in participants' baseline characteristics between the groups, we will adjust the D-in-D estimators by these covariates using generalized linear regression models. Ethics and dissemination: The study was approved by the IMSS Ethics and Research Committee (registration number 2018-785-095). All participants will sign a consent form prior to their participation. The study results will be disseminated to IMSS authorities, healthcare providers and the research community.
The goal is find out if the use of Electronic cigarettes (EC) leads to the same changes that we see in blood vessels of traditional cigarettes (TC) users. The investigators will also enroll non-smokers as "controls", against which they will measure changes in blood vessels in TC and EC users.
Atherosclerosis progressively occurs with increasing age in the general population. So far most dietary intervention studies with flavanols were performed over short time frames and in small groups of young healthy and older patients with manifest cardiovascular disease, respectively. Vascular health is defined as absence of vascular disease and the presence of optimal parameters that determine the development and progression of arteriosclerosis (endothelial function, blood pressure, plasma lipids, and glucose). It is not clear whether flavanols can improve parameters of vascular health, most importantly endothelial function, when given repetitively to healthy middle aged and which factors affect the efficacy of flavanol interventions.
In this study, the beneficial effect of a nutrient enriched dairy product will be investigated on vitamin K-status. To achive this benefit, the study product contains extra vitamin K2. In addition, extra dairy minerals have been added to the study product that may support general health.
The effects of two vitamin K-forms on carboxylation of the vitamin K-dependent proteins osteocalcin and matrix-gla protein will be compared after supplementing these vitamins in a nutritional dose range. The investigators hypothesized that MK-7 is more effective than K1 at a dose comparable to the RDA of vitamin K.
The purpose of this study is to test the effects of endurance exercise training on arterial structure and function, and to examine potential mechanisms producing changes in arterial structure and function in young (18-35 years of age) African Americans when compared to Caucasians.
