OBJECTIVE:Few studies have examined brain changes in response to effective weight loss; none have compared different methods of weight-loss intervention. Functional brain changes associated with a behavioral weight loss intervention to those associated with bariatric surgery were compared.

METHODS:Fifteen obese participants were recruited prior to adjustable gastric banding surgery and 16 obese participants were recruited prior to a behavioral diet intervention. Groups were matched for demographics and amount of weight lost. Functional magnetic resonance imaging scans (visual food motivation paradigm while hungry and following a meal) were conducted before and 12 weeks after surgery/behavioral intervention.

RESULTS:When compared to bariatric patients in the premeal analyses, behavioral dieters showed increased activation to food images in right medial prefrontal cortex (PFC) and left precuneus following weight loss. When compared to behavioral dieters, bariatric patients showed increased activation in bilateral temporal cortex following weight loss.

CONCLUSIONS:Behavioral dieters showed increased responses to food cues in medial PFC-a region associated with valuation and processing of self-referent information-when compared to bariatric patients. Bariatric patients showed increased responses to food cues in brain regions associated with higher level perception-when compared to behavioral dieters. The method of weight loss determines unique changes in brain function.

Bariatric Surgery Registry

July 1st, 2014 | Posted by Sue in Lifestyle | News | Research - (0 Comments)

Our clinics in Adelaide and Perth are enthusiastic participants in the Australian national Bariatric Surgery Registry.

This bariatric registry has been established by the Obesity Surgery Society of Australia and New Zealand in conjunction with the Monash University NHMRC Centre for Research Excellence in Patient Safety. It aims to capture and track all bariatric procedures performed across Australia and New Zealand, focusing not only on the safety of the initial procedure but also longer-term effects on weight and health, as well as the longer-term adverse events.

Quality and safety registries have been shown to improve health outcomes. Monitoring of outcomes following orthopaedic surgery through the Australian Joint Replacement Registry, for instance, recently led to the withdrawal of a defective hip prosthesis from the market.

The pilot phase of this project is now completed, and data is being provided for patients for more and more hospitals as they grant ethical approval. There is, of course, an opt-out clause. If you would prefer your data to be kept from the confidential registry, please let the staff know when you next come to the clinic.

Who needs surgery the most?

October 25th, 2013 | Posted by Sue in Lifestyle | Research - (0 Comments)

Quoting from Bariatric News:

“If we have to decide who should get the surgery first, it should be based on who has the highest risk of mortality,” said Arya Sharma, chair in obesity research and management, scientific director of the Canadian Obesity Network. “We looked at thousands of patient files and many different parameters, and surprisingly enough it came down to three things, if you’re male, you’re a smoker and you have diabetes, you have the highest risk. These surgeries are being done, but are the wrong people getting them? The current BMI cut-off is missing the boat on those who need it most. Having diabetes is more important than BMI as a risk factor. Our research showed BMI didn’t really matter, so size alone isn’t a good way to decide who should get the surgery.”
The research showed that diabetes was the strongest predictor of death, noting that obese patients with diabetes were more than twice as likely to die as obese patients without diabetes. Smoking increased risk of death 1.6 times, and being male increased risk 1.5 times. 
“We think this will be a useful tool for physicians,” added Padwa. “It’s simple math that will predict a patient’s risk of death. For example, if you’re a middle-aged, male smoker with diabetes, your risk of dying in 10 years is 10 times higher than that of a young, female non-smoker who doesn’t have diabetes—irrespective of BMI.”
The research was funded by the Canadian Institutes of Health Research.
 

So, the simplest thing to do to reduce your health risks is to stop smoking. This will also improve your results from surgery if it is required.

Secondly, there is evidence to support weight loss surgery for patients with less severe obesity if they have diabetes. The sooner you lose weight after first discovering diabetes, the better the result. Sometimes, the diabetes seems to completely disappear.

Sleep apnoea

March 18th, 2013 | Posted by Sue in Lifestyle | News | Research - (0 Comments)

A recent study at the Perelman School of Medicine at the University of Pennsylvania has shown that when Sleep Apnoea is treated by CPAP mask alone, high blood pressure does not improve significantly. However, when it is treated with CPAP as well as weight loss, the high blood pressure improves rapidly.    (more…)

Researchers at Laval University have concluded that after bariatric surgery, mothers who were previously obese give birth to children with an altered genetic makeup. This leads to reduced cardiovascular risk factors in the child as he or she grows to adulthood.
The study was presented at the Canadian Cardiovascular Congress, but the paper is not yet published.

“We know our genetic makeup influences our children’s risks – but so can our environment,” said Dr Beth Abramson, spokesperson for the Heart and Stroke Foundation, who helped fund Dr Guénard’s research.

“For example, if a disease runs in a family, we know to watch out for it in the children as they age,” she said. “This study shows that external factors also influence our risk for heart disease – and that of our offspring by switching genes on or off in our DNA; providing a glimpse as to why this occurs. This is why lifestyle behaviours are so important.”

Why Psychology?

September 25th, 2012 | Posted by Kristen in Lifestyle - (0 Comments)

An important component of our program is your interaction with our Psychologist, who you might consider your Lifestyle Coach.

The two main parts of the Psychology Program are:

  • With your Psychologist or Counsellor, you will explore your expectations of surgery and the program, set clear goals and develop strategies to help you remain focused and motivated.  You will receive information to enhance your wellbeing.
  • You and other patients may choose to meet to share thoughts, feelings and experiences. These sessions have been shown to be highly effective and popular with patients following weight loss surgery, mostly because they offer support and input from others who have recently been through similar experiences and are working towards similar goals.

The nutritious recipies have been designed and tested to cook for 1 person and are designed to be well tolerated by Gastric Band Patients for day-to-day eating. Author Helen Toouli has been involved with the Adelaide Bariatric Centre – her husband is our own Professor Jim Toouli! It can be purchased from the reception desk at our clinics in Perth or Adelaide, or from the Band Buddies website.

The Gastric Band Nutrition Essential (book and DVD)

This book will help you learn how to feel full for longer with the gastric band, help you to keep your food, teach you how to lose weight without dieting and help you get a better understanding of how to deal with head hunger.

Obesity Linked To Early Growth

June 19th, 2012 | Posted by Kristen in Lifestyle | Research - (0 Comments)

Obesity Linked To Early Growth

Accelerated growth in early childhood is an indicator for chronic obesity in adulthood, a 38-year longitudinal New Zealand study published in the Archives of Paediatric & Adolescent Medicine has found. The finding was part of a study measuring genetic markers for later obesity, which found that individuals with higher genetic risk scores were more likely to be chronically obese in adulthood. The genetic risk first manifested as rapid growth during early childhood but was unrelated to birth weight. The researchers said their results could inform public health initiatives and research priorities.

 

Study: 42% Of Americans Will Be Obese By 2030.

A new report on US obesity projections received heavy coverage, with network news broadcasts devoting nearly four minutes to the study. Most sources emphasized the costs and health burden associated with an increasingly obese population, but many also pointed to the fact that obesity rates have stabilized in recent years. (more…)
