The brain plays a major role in the overconsumption of high fat/high sugar foods and this contributes to obesity but it receives little attention when it comes to developing novel treatments. My lab showed that a FDA-approved smoking cessation medication, that is a nicotinic receptor modulator, decreased the overconsumption of sugar. This project aims are to identify which nicotinic receptors and brain circuits are involved in the overconsumption of sucrose to improve treatments for obesity.
A Dietary Intervention In Gestational Diabetes To Reduce Child Obesity: A Randomised Controlled Trial

Funding Amount
$354,715.00
Summary
Women with gestational diabetes (GDM) whose blood glucose levels (BGL) are not well controlled have a higher chance of giving birth to large babies. These babies are at high risk of becoming overweight children and adults. Preventing child obesity therefore requires appropriate intervention during pregnancy complicated with GDM. This study will determine the ability of specific dietary advice (aimed at reducing maternal BGL) to reduce the risk of large babies in a typical ante-natal setting.
The Role Of Bisphenol A In The Development Of Chronic Disease

Funding Amount
$397,549.00
Summary
There is accumulating evidence to suggest that the environment we live in may be important in the development of chronic disease. This project examines a key environmental toxin Bisphenol A (BPA) and explores the role it has in the development of diabetes, obesity and cardiovascular disease (CVD). In this project, we will explore whether there is an independent relationship between BPA and the development of diabetes, CVD and obesity in humans in a prospective setting.
Vitamin D, Bone Loss, Fracture And Mortality Outcome

Summary
Vitamin D most commonly from sunlight exposure is considered an important determinant of health, including the liability to falls and fractures; not only in the elderly but in adulthood in general. This study aims to distinguish if low vitamin D levels cause adverse health outcomes or relate to ill health, limited sunlight exposure and nutritional change. Only if low vitamin D level is causative of ill health does replacement make good public health sense.
Beige fat is a recently described kind of fat which instead of storing fat and contributing to obesity burns energy and burns glucose. It helps to combat obesity and diabetes. If it could be increased and switched on, it would help to treat obesity and diabetes. This grant will study a new pathway to try to increase the amount of beige fat and to increase its activity.
Generating Evidence Of Reduced Rates Of Overweight/obesity In Children: Value Adding To Four Established Australasian Early Intervention Trials

Summary
Childhood obesity is a major health problem. Trials are now being done to see whether helping families when their baby is young will reduce the rate of overweight children. We will combine data from these trials (1800+ children) to see if the programs work. To get maximum information we need to combine the line-by-line raw data from each patient in each trial. This is called an individual patient data meta-analysis. It is the best method for finding reliable answers to important health issues.
Promoting Protective Feeding Practices To Prevent Childhood Obesity: Follow Up Of A Successful Obesity Prevention Program Commencing In Infancy.

Summary
Almost one in four Australian children are overweight by the time they start school and at increased risk of becoming overweight adults. This study will evaluate if an intervention to equip parents with the confidence and skills to initiate and maintain positive early feeding practices can foster healthy food preferences, dietary intakes and eating patterns and growth up to five years of age. This is consistent with government focus on early childhood as the foundation for health and well-being.
Modafinil For Neurobehavioural Dysfunction In Sleep Apnea Patients Who Cannot Use Standard Device-based Treatments.

$505,830.00
Summary
Obstructive sleep apnea (OSA) is often caused by obesity and can result in fall-asleep car crashes. It is often treated by mechanical devices that keep the sleeping airway open. Unfortunately, around half of all patients cannot tolerate these treatments. We propose to help patients reduce obesity with a lifestyle intervention program whilst testing whether their daytime symptoms of sleepiness and poor driving ability can be treated with a wake-promoting drug called modafinil.
Activation Of HSP72 In Skeletal Muscle As A Therapeutic Target For Obesity

Funding Amount
$656,033.00
Summary
We recently discovered that activation of a protein, namely Heat Shock Protein 72, can prevent obesity and insulin resistance in mice. We have developed a small molecule activator of this protein which has undergone preliminary human clinical trials. This project will extend upon this initial finding to determine the precise mechanism by which activation of this protein prevents obesity and insulin resistance.
Evaluation Of The Obesity Paradox In Diabetes: A Longitudinal Case-Control Study Of Half A Million Patients

Summary
Obesity is a risk factor for developing diabetes. However, recent studies reported increased mortality risk associated with normal body weight in people with incident diabetes compared to overweight or obese patients. This “obesity paradox”, where being overweight appears to be protective, is new in diabetes. The mechanism behind this is not known. Using 20 years of follow-up data on 500,000 diabetes and control patients, this study proposes to find possible explanations behind obesity paradox.
