Filter by:Background: Exercise has been proven to effectively reduce incidence of diabetes mellitus and metabolic syndrome. However, there is controversial data from prior studies to inform the type of exercise training recommendations. Aim: The aim of this study will determine the differences of different type of exercise in the effects of reducing insulin resistance and visceral adipose tissue for community residents. Methods: The four-arm randomized controlled trial will conducted in adults aged 40 to 70 years old in Tainan. A total of at least 177 patients will randomly assign to the group of aerobic exercise (AE), aerobic exercise combined with resistance exercise (RE), AE combined with medium intensity interval training, and placebo. The participants in exercise group will received 12 weeks, 3 times per week program, including twice a week intervention guided by the intervenors, and once a week exercise guided by the video at home. All the exercise keeps moderate-intensity by monitoring with 64%-75% of the maximum heart rate. Insulin resistance status will be checked by HOMA index at baseline and at exercise intervention after 12 weeks (HOMA index= insulin μU/mL）× glucose（mmol/L）/22.5). Relevance to clinical practice: The research findings will help the clinical health works to know which type of exercise is the best choice in reducing insulin resistance and visceral adipose tissue in community residents, and can be promoted to the general public to reduce the prevalence of metabolic syndrome as well as prevent the root causes of ill health.
In this project, investigators explored the role of the particles that carry "bad cholesterol" in the blood (termed LDL) that are known to promote heart disease, in the promotion of type 2 diabetes (T2D) in humans. In specific, they investigated how these particles may induce the activation of an immune pathway in human fat tissue leading to multiple anomalies that favors T2D. They also explored whether omega-3 fatty acids, which are the type of fat found in fish oils can counterbalance the negative effects of LDL in fat tissue, thus providing a natural way to help reduce the risk for T2D in subjects with elevated blood LDL. To do so, 41 subjects who were free of disease or medication affecting metabolism were enrolled at the Montreal Clinical Research Institute between 2013 and 2019 and were placed on an intervention with omega-3 fatty acids supplementation for 12 weeks (2.7 g/day, Triple Strength Omega-3 from Webbers Naturals). Investigators examined the effects of LDL and omega-3 on risk factors for T2D before and after the intervention in the whole body and specifically in fat tissue biopsies taken from the hip region. Eighty percent of the subjects who were enrolled into the study completed the intervention.
Every 3 minutes a new case of diabetes is diagnosed in Canada, mostly type 2 diabetes (T2D) increasing the risk for heart disease. T2D and heart disease share many common risk factors such as aging, obesity and unhealthy lifestyle. Paradoxically however, while lowering blood LDL, commonly known as "bad cholesterol", is protective against heart disease, research over the past 10 years have shown that the lower is blood LDL, the higher is the chance of developing T2D. This phenomena is happening whether blood LDL is lowered by a common drug against heart disease called Statins, or by being born with certain variations in genes, some of which are very common (~80% of people have them). To date, it is unclear why lowering blood LDL is associated with higher risk for diabetes, and whether this can be treated naturally with certain nutrients. Investigators believe that lowering blood LDL by forcing LDL entry into the body tissue through their receptors promotes T2D. This is because investigators have shown that LDL entry into human fat tissue induces fat tissue dysfunction, which would promote T2D especially in subjects with excess weight. On the other hand, investigators have shown that omega-3 fatty acids (omega-3) can directly treat the same defects induced by LDL entry into fat tissue. Omega-3 is a unique type of fat that is found mostly in fish oil. Thus the objectives of this clinical trial to be conducted in 48 subjects with normal blood LDL are to explore if: 1. Subjects with higher LDL receptors and LDL entry into fat tissue have higher risk factors for T2D compared to subjects with lower LDL receptors and LDL entry into fat tissue 2. 6-month supplementation of omega-3 from fish oil can treat subjects with higher LDL receptors and LDL entry into fat tissue reducing their risk for T2D. This study will thus explore and attempt to treat a new risk factor for T2D using an inexpensive and widely accessible nutraceutical, which would aid in preventing T2D in humans.
This observational study will evaluate the effect of puberty suppression on insulin sensitivity, metabolic rate and vascular health among transgender female youth at baseline and 6 months after initiation of a gondoatropin releasing hormone agonist compared to matched cisgender male controls.
There is a distinct lack of experimental evidence on whether breakfast consumption and omission affect energy balance-related variables. This research is of particular relevance to adolescent girls due to concerns of low rates of breakfast consumption and physical activity in this population. This study aims to compare the effect of seven consecutive days of breakfast omission with standardised breakfast consumption on free-living physical activity energy expenditure, energy intake and perceived appetite and energy levels in adolescent girls.
It is an interventional study in which 60 women estimated to enroll according to random allocation and assigned into two groups equal. The study group will receive active low level laser in addition to diet recommendations while the control group will stick to the same line of treatment but with sham laser application. The laser consists of semiconductor and operates at a wavelength of 650 nanometre. The laser installed in the watch comprises 10 individual laser beams for the wrist and an additional adapter for nasal stimulation. The output power is 5 megawatt, but it can also be adjusted. The device operates at an ambient temperature of -20 to +40 ° C and a relative humidity of ≤ 85%. The laser watch can be used for a variable irradiation period of 10-60 min. the device will be applied on specific acupuncture points (N acupuncture point, Radial artery acupuncture points, and ulnar artery acupuncture points) combined with nasal laser irradiation at the same time, once per day, 3 times per week for three months
Childhood obesity is one of the most serious public health problems of the 21st century. It is considered that if there are no changes in prevention and treatment strategies there will be an increase to 70 million obese children by 2025. Of the only pharmacological treatments accepted at this age to improve insulin resistance is metformin, but it can condition gastrointestinal, muscular and hepatic adverse events. Cinnamon is an alternative therapy, which due to its high concentrations of polyphenols, improves insulin resistance by decreasing the proinflammatory environment that occurs in this group of patients, and unlike metformin with less frequent adverse events. The effectiveness of cinnamon has been demonstrated by decreasing insulin resistance in the adult population.
PURPOSE: to determine the effect of interval training on sex hormones, metabolic and tumor markers BACKGROUND: Cancer is one of death top causes in many countries1. In Egypt for example, cancer incidence is 157.0 per 100 000 women with probability increasing up to three-fold by 2050 especially in older adult women2. Who exhibit multiple factors leading to cancer including but not limited to physical inactivity and postmenopausal obesity which considered the starting point of developing insulin resistance3. High blood insulin level stimulates cancer progression by enhancing cell proliferation, decreasing cells apoptosis, increased level of fatty acids in conjunction with higher tumor cell formation capacity invasion and survival4. Moreover, high level of insulin resistance and adipose tissue increase the hormonal level of estradiol and testosterone coupled with lower SHBG level. It was noticed that being postmenopausal women with high adipose tissue content will increase the risk of having cancer in which adipose tissue is considered as the main source of steroids hormones that functioning in a different way rather than in premenopausal age. Based on the mentioned underlying conditions, postmenopausal women subjected to have variable types of cancer such as breast, endometrial, stomach, etc6. So, regular screening of cancer incidence especially in high-risk women through tumor indicators is necessitated to work against further cancer progression. CEA and CA125 are low-cost tumor blood biomarkers used widely for early cancer identification, recurrence monitoring and follow up which linked to proinflammatory cytokines production . HYPOTHESES: may have no effect to interval training on sex hormones , metabolic and tumor markers in postmenopausal women RESEARCH QUESTION: Is there effect to interval training on sex hormones , metabolic and tumor markers in postmenopausal women?
Chronic hepatitis C infection has been linked to insulin resistance, which is the essential component of metabolic syndrome and type 2 diabetes mellitus. Resistin; an adipokine, has been demonstrated to stimulate the secretion of several inflammatory factors known to play a role in the induction of insulin resistance. we investigated the changes in insulin resistance after hepatitis C clearance in the era of direct antivirals.
The aim of the present study is to evaluate the implication of adipokines, inflammation, insulin resistance and endothelial dysfunction in the pathogenesis of preeclampsia and in pregnancy related complications.
