New Vagal Blocking system for controlling hunger
New Vagal Blocking system for controlling hunger
A new treatment procedure is in the offing for obesity and gastrointestinal problems. EnteroMedics Inc.'s VBLOC Therapy (Vagal BLocking for Obesity Control) is being designed to control the function of vagal nerves that control the feelings of hunger and satiety. Clinical trials have proved the efficacy of this system.
Therapy Highlights
a. This is an implantable system.
b. It is designed to regulate nerve and organ function.
c. It will regulate the activities of the stomach and pancreas.
d. It involves the beaming of high frequency, low power electrical signals through implanted leads.
e. These signals block vagal nerve transmission which regulates stomach activities.
f. The leads are implanted through laparoscopy.
g. This system is safe and effective.
h. It can be adjusted to suit individual requirements.

Severe obesity increases risks of health problems during surgery
Severe obesity increases risks of health problems during surgery
Advisory highlights:
Heart problems in particular are often underestimated during a physical examination in the severely obese patient, according to the advisory.
“A severely obese patient can be technically difficult to evaluate prior to surgery,” said Paul Poirier, M.D., Ph.D., lead author of the advisory and associate professor at Université Laval Institut universitaire de cardiologie et de pneumologie Hôpital Laval in Québec, Canada. “For example, severely obese people might feel chest tightness that could be a symptom of their obesity or of an underlying cardiac problem. Doctors need to carefully evaluate severely obese patients before they have surgery.”
Severe obesity describes people with a body mass index (BMI) of 40 or higher. This type of obesity, affecting 3 percent to 4 percent of the population, is associated with health problems that may lead to disability and death.
“In the obese population, the severely obese make up the fastest growing segment,” Poirier said.
The advisory provides cardiologists, surgeons, anesthesiologists and other healthcare providers pre-operative evaluation recommendations, along with information on managing and caring for obese patients during and after any surgery, including such procedures as knee replacement, abdominal surgery or a heart operation.
Conditions associated with obesity that could increase heart risks in surgery include:
The advisory offers a proposed scoring tool to assess risk for patients preparing to have weight-loss surgery and Poirier says additional research is also needed to develop obesity risk scores to identify patients at increased risk specific to other surgeries.
Healthcare providers should be aware that severely obese patients are more likely to stay on a ventilator longer and have a longer hospital stay than patients who are not severely obese, the statement’s authors said.
It’s reasonable to do an electrocardiogram and a chest X-ray in this population, and other non-invasive testing, including exercise testing, may also be advisable, according to the advisory.
However, “some surgeons are under the impression that severely obese patients are more likely to die in surgery than people who are not obese, and won’t operate on them as a result,” Poirier said. “This is not true. Severely obese patients are at increased risk for pulmonary embolism, wound infection and other conditions. But they are not more likely than their lower-weight counterparts to die as a result of surgery.”
Severely obese people should ask their surgeons whether a particular surgery is safe for a patient their size.
“Since recovery can be a problem for these patients, we recommend that they take steps to be as healthy as possible before going into surgery,” Poirier said. “For example, the person with diabetes should get his or her blood sugar under control.”

Severe obesity increases risks of health problems during surgery
Advisory highlights:
- Severe obesity can pose special challenges, including cardiac risks, in patients undergoing surgery; healthcare providers must carefully evaluate those risks and not underestimate them.
- The risk of a cardiac event before, during or after surgery in obese patients is related to the type and severity of their heart’s condition, as well as other health conditions and the type of surgery they are having.
- Severely obese patients are at higher risk than non-obese patients for complications after surgery and for prolonged hospital stays; however, they are not at higher risk for death.
Heart problems in particular are often underestimated during a physical examination in the severely obese patient, according to the advisory.

Conditions associated with obesity that could increase heart risks in surgery include:
- Heart failure
- Atherosclerosis (thickened or narrowed arteries)
- High blood pressure
- Heart rhythm disorders
- History of blood clots (especially pulmonary embolism)
- Poor exercise capacity
- Pulmonary hypertension related to sleep apnea

Health risks begin in overweight range, BMI doesn’t tell whole story
Health risks begin in overweight range, BMI doesn’t tell whole story
Advisory highlights:
About one-third of the U.S. population is overweight — the middle range between normal weight and obesity. Overweight in adults is a BMI of 25.0 to 29.9. BMI is a numerical value of weight in relation to height.
Studies that examined the relationship between overweight (as measured by BMI) and risk of death from all causes (often referred to as total mortality) have had contradictory results. However, considering death from all causes overlooks the role that overweight may play in the development of risk factors for cardiovascular diseases.
Even among the young, overweight is related to the development of serious risk factors for cardiovascular disease, such as high blood pressure, obesity, elevated levels of cholesterol and type 2 diabetes.
Part of the problem with quantifying the true impact of overweight lies in the way it’s commonly measured, say the experts. The widely-used body mass index doesn’t distinguish between fat mass which is related to important health concerns — such as type 2 diabetes — and lean mass, including muscle, which reduces health risks. Also, BMI does not directly measure the distribution of fat, such as whether there is greater fat at the waist than at the hips, which may be more detrimental to health.
Focusing on the relationship between total mortality and BMI misses the “larger picture,” the statement said.
“This larger picture includes important relationships between BMI and other health outcomes, such as cardiovascular disease and its risk factors,” said Cora E. Lewis, M.D., M.S.P.H., lead author of the advisory and professor of medicine and public health at the University of Alabama at Birmingham. “Arguably, the most important relationship among the cardiovascular disease risk factors is diabetes, which is significantly more common in overweight than in normal-weight people.”
The advisory recommends doing research on overweight and health, beyond studies that focus solely on the relationship between total body mass index and risk of death.
“Meanwhile, we cannot afford to wait for this research to begin addressing the problem of overweight in our patients and in our society,” write the advisory authors.
An increasing number of children are overweight, which puts them at risk for developing higher than normal blood pressure, blood cholesterol and blood sugar.
“Weight gain is progressive and weight loss difficult. Although a young child is unlikely to have a heart attack, overweight children are likely to become overweight or obese adults, which puts them at risk for cardiovascular events as they mature. Achieving and maintaining a healthy body weight is of high importance for all Americans,” said Lewis.
Physical inactivity and excess weight increase risk of death and other adverse health outcomes; so overweight and obese persons in particular would benefit from adopting a physically active lifestyle and healthy eating habits.
Advisory co-authors include Kathleen M. McTigue, M.D., M.P.H.; Lora E. Burke, Ph.D., M.P.H.; Paul Poirier, M.D., Ph.D.; Robert H. Eckel, M.D.; Barbara V. Howard, Ph.D.; David B. Allison, Ph.D.; Shiriki Kumanyika, Ph.D., M.P.H.; and F. Xavier Pi-Sunyer, M.D. Author disclosures are available on the manuscript.

Sleeplessness a Weighty Matter
Sleeplessness a Weighty Matter
MONDAY, June 8 (HealthDay News) -- Not getting enough sleep can make you start packing on the pounds almost immediately, a new study has found.
In the study, researchers put 92 healthy men and women aged 22 to 45 through an 11-day, controlled sleep-restriction experiment in a laboratory.
During the first two nights, study participants spent 10 hours a night in bed, followed by five nights of sleep restriction, and finally, four nights of varying recovery. Nine well-rested participants served as controls.
The sleep-deprived participants gained an average 1.31 kilograms (2.9 pounds) by the end of the study period. The well-rested controls gained none, according to the study to be presented Monday at the Associated Professional Sleep Societies annual meeting, in Seattle.
Participants were given three regular meals per day and access to healthy snacks. On the sleep-restriction nights, a small sandwich was provided at 1 a.m., the study authors noted.
Despite gaining weight, the sleep-deprived participants reported that their appetites had decreased, that they had fewer food cravings and that they had eaten less food, the researchers found. This contradicts previous research that has suggested lack of sleep may fuel cravings for the quick energy of carbohydrates.
Even though this study found the opposite -- lack of sleep didn't increase the desire to eat -- other factors may explain the weight gain, the researchers said. The sedentary environment of the laboratory and the opportunity to snack for longer periods due to reduction in time spent asleep might have encouraged noshing.
"During real-world periods of sleep restriction [say during shift work], people should plan their calorie intake over the time they will be awake, eating small, healthy meals," Siobhan Banks, a research fellow at the University of South Australia, said in a news release from the American Academy of Sleep Medicine.
To ward off weight gain, it's also a good idea to keep low-fat, low-sugar snacks on hand to reduce the temptation to eat high-fat, high-calorie comfort foods, and to maintain a regular exercise routine, Banks added.
"Even though people may feel tried, exercising will help regulate energy intake balance," Banks explained
