Filter by:The study aims to investigate the effects of Cognitive Behavioural therapy intervention on sleep and it's effects on well-being, dietary intake and food preferences during COVID-19. The study will investigate whether delivery of a CBT intervention will lead to an improvement in sleep quality and sleep duration and will consequently improve metabolic health. The participants will be randomized into two groups with one half in the intervention arm and the other in the control arm of the study.
There is strong scientific data that supports that short-term protein restrictive diets reduce surgical stress responses. The investigators are hoping to use the information collected from the blood serum and muscle tissue of healthy subjects to help understand the baseline and early changes in muscle energetic and cell-mediated inflammation. The study team hopes to use the data collected in this pilot study to compare with patients undergoing open abdominal aortic aneurysm (AAA) repair in a future study
The interplay between diet and the gut microbiota has been implicated in the onset of cardiovascular disease. The gut microbiota displays diurnal rhythms, which may be influenced by meal timing. This study aimed to investigate the effect of main meal consumption timing on the microbiota and the cardiometabolic factors of the host using a cross-over RCT in healthy adults The main outcome measurements will be: a) changes in gut microbiota composition based on 16S rRNA gene amplicon sequencing and shotgun metagenomics, b) changes in bacterial functional capacity) and urinary/faecal metabolomics, c) changes in targeted bacterial metabolites, d)Inflammatory markers The aim of this study is to explore the effect of the timing of main meal consumption on gut microbiota and immune response in healthy adults.
Current efforts to arrest the epidemic of type 2 diabetes mellitus (T2DM) have had limited success. Thus there is an urgent need for effective approaches to prevent the development of T2DM. It is widely accepted that the current epidemic is driven by an increase in global food abundance and reduced food quality, making changes in diet a key determinant of the T2DM epidemic. Dietary factors can affect cardio-metabolic health; among these factors, advanced glycation end-products (AGEs) in food are potential risk factors for insulin resistance and T2DM. AGEs are a heterogeneous group of unavoidable stable bioactive compounds. Endogenous formation of AGEs is a continuous naturally occurring process, and is the result of normal metabolism. However, increased formation of AGEs occurs during ageing and under hyperglycaemic conditions. AGEs are implicated in the development of diabetes and vascular complications. Over the past several decades, methods of food processing have changed and meals now contain excess fat and sugar and are most susceptible for the formation of AGEs. In addition, AGEs in food are highly desirable due to their profound effect on shelf life, sterility, flavour, colour, and thus food consumption. Hence, a substantial portion of AGEs are derived from exogenous sources, particularly food. These exogenous AGEs are potential risk factors for insulin resistance and the development of T2DM. The investigators recently found that dietary AGEs represent a significant source of circulating AGEs, and have similar pathogenic properties compared to their endogenous counterparts including the development of insulin resistance and T2DM. Taken together, dietary AGEs are proposed to play a pivotal role in the development and progression of T2DM and its complications. Reduction of dietary intake of AGEs may therefore be an alternative strategy to reduce the risk of vascular disease and insulin resistance. The investigators therefore hypothesize that dietary restriction of AGEs in overweight individuals improves insulin sensitivity, β-cell function, and vascular function.
This is a single-blind, randomized trial. Based on inclusion and exclusion criteria, 253 eligible volunteers, who were 25-60 years old, with overweight/obese and prediabetes are assigned to one of three dietary patterns: healthy Jiangnan, restricted-calorie; Mediterranean, restricted-calorie; or typical Shanghai, restricted-calorie. The Shanghai Institutes for Biological Sciences of the Chinese Academy of Sciences(CAS) cooperated with Ruijin Hospital to conduct the study which is funded by the CAS. The study' protocol has been approved by the Ethics Committee of Shanghai Institutes for Biological Sciences. The main purpose of this study is to clarify: the efficacy of traditional Jiangnan dietary pattern, Mediterranean dietary pattern and the current Shanghai dietary pattern in improving overweight/obesity, glucose homeostasis, other cardiovascular metabolic risk factors and their main regulatory factors in Chinese.
To highlight the importance of protein quality rather than the total protein content of a meal, the investigators will demonstrate that unlike high quality proteins, a single meal containing 30 g of an incomplete protein source does not stimulate skeletal muscle protein synthesis. Secondly, the investigators will directly challenge a prevalent, but untested, assertion that has the potential to negatively impact health. The goal is to demonstrate that complementary plant-proteins (i.e., two or more incomplete protein sources) must be consumed at the same meal to stimulate protein synthesis.
Dietary antioxidants might protect from the development of chronic diseases by reducing levels of oxidative stress. The investigators therefore investigated the effect of dietary Non Enzymatic Antioxidant Capacity, which measures interactions between antioxidants in the whole diet, on the risk of 1) myocardial infarction and 2) osteoarthritis.
To obtain up-to-date data on nutrient intakes in adults, a national dietary survey - the EU Menu study will be conducted during 12 consecutive months in 2017/2018, providing data on the consumption of foods and enabling the assessment of energy and macronutrient intakes. Participating subjects will be invited to NUTRIHEALTH study for assessment for micronutrient status (focusing into vitamin D, folic acid, vitamin B12, and iron) and medical examination, in which thyroid size will be aslo measured, to investigated thyroid epidemiology in Slovenia.
Enrollment of a population-based, prospective cohort of 3298 stroke-free adults was completed in 2001 and annual follow-up has continued since then. This collaborative study is the first prospective cohort study among whites, blacks and Caribbean Hispanics living in the same community. This grant supports continued follow-up and outcome detection and expansion of data collection in this cohort. The aims are to evaluate the relationship between vascular outcomes (stroke, myocardial infarction (MI), and vascular death) and insulin resistance, carotid intima-media thickness, carotid distensibility, and quantitative magnetic resonance imaging (MRI) measures of vascular subclinical brain disease and to determine if MRI subclinical disease accounts for race/ethnic differences in cognitive impairment. To accomplish these aims further data collection using the population-based, prospective cohort study is proposed. Stored baseline serum will be used to measure fasting insulin levels to evaluate insulin resistance. High-resolution carotid imaging data will be collected at subsequent visits to expand the measurements of subclinical carotid disease to 1300 subjects. MRIs and a neuropsychological battery emphasizing frontal executive domains will be done on 1300 subjects and quantitative analyses performed to measure white matter hyperintensities, silent infarcts, and silent cerebral microbleeds. Starting in 2005, subjects enrolled in the MRI substudy began to have echocardiograms and 24hour ambulatory blood pressure monitoring. Subjects will be followed by annual telephone interviews to ascertain stroke, MI, death, and changes in cognitive state. In-person assessment will be done for all subjects who screen positive. Community stroke surveillance will be maintained to insure stroke detection among the cohort. Specific diagnostic committees classify stroke, MI and vascular death.
The study tested an intervention that used a cue-removal and implementation intentions based strategy to change habitual dietary behaviors. The intervention was evaluated using a randomized experimental design that consisted of two conditions including (1) a control condition or (2) a cue and implementation intention-based intervention. High schools (N=22) were randomly assigned to one of the two conditions. Families (N=187), with a family defined as an adolescent and one participating parent, were recruited from within the 22 schools. All of the families from each school were assigned to the same condition. Families that were eligible for the study and that were interested in participating scheduled an appointment to complete informed consent. After written parental consent and youth assent was obtained, the participants had their height and weight measured and completed a series of questionnaires programmed on laptops. In addition, the adolescent took part in a 24 Hour Dietary Recall Assessment. The family was also informed that a second 24 Hour Dietary Recall Assessment would be administered to the adolescent over the phone in approximately 3-14 days. Families that were from a school assigned to the control condition received an intervention on sun safety that consisted of a 10-minute meeting with a trained Health Coach, two generic newsletters, an email, and a text message. Families from a school assigned to the cue- and implementation intentions condition received an intervention on healthy snacking and the reduction of sugar sweetened beverage consumption that consisted of a 90-minute meeting with a trained Health Coach, two 20-minute phone calls, four tailored newsletters, and a series of emails and text messages. Both of these interventions were delivered over a period of 3-10 weeks depending on the self-directed pace of the participants. All participants were then asked to complete a follow-up assessment appointment three months after their original consenting appointment. Our hypotheses focused on dietary behaviors and stated that adolescents assigned to the cue-removal and implementation intentions intervention would consume significantly fewer daily servings of high fat snacks, high sugar snacks, and sugar sweetened beverages than adolescents in the control condition.
