People with obesity who used a device that allowed them to aspirate 30% of their stomach contents through a gastric tube lost about 21% of their total body weight over three years. The device, presented at the American College of Gastroenterology's James W. Freston Conference, may also help to improve type 2 diabetes, hypertension and hyperlipidemia.
Engineers at the University of Wisconsin-Madison have developed a stomach implant device that could reduce food intake in people with obesity by producing electric pulses "in response to stomach movements, and transmits them through the vagus nerve to the brain as an artificial fullness signal," said professor Xudong Wang. Published in the journal Nature Communications, the study showed that rats implanted with the device weighed 38% less after 100 days, compared with control rats.
Data shows that body mass index has increased steadily worldwide between 1975 and 2016 among men, women and children. The information presented at the Current Status and Response to the Global Obesity Pandemic workshop held in Washington, D.C., also included recommended treatment options such as education and increased activity.

UK researchers used a cohort of 9,652 individuals, mean age of about 55, and found that higher levels of body mass index, fat mass and waist-to-hip ratio were associated with lower gray matter volume in the brain, putting people at an increased risk for age-related brain diseases such as dementia. The findings were published in the journal Neurology.
Adolescents who experienced an adverse childhood event had 1.2 times, 1.4 times and 1.5 times increased likelihood of being overweight, obese and severely obese, respectively, compared with those without any ACEs, with adiposity risk increasing with more ACEs reported, researchers reported in The Journal of Pediatrics. The findings also showed ACEs were more prevalent among girls.
Children below the 85th percentile of fat mass who had greater total fat mass had higher areal bone mass density z-scores with fat-free mass being held as constant, but those above the 85th percentile with elevated fat mass had lower aBMD z-scores, with the negative correlation between greater fat mass and reduced aBMD z-scores driven by elevated abdominal fat, researchers reported in the journal Bone. The findings, based on data involving 876 youths, "suggest that as early as childhood, excess abdominal adiposity may negatively influence bone health," said researcher Lisa Rokoff.
Statin users with high cardiorespiratory fitness levels were at a lower risk for type 2 diabetes, compared with individuals with low or moderate cardiorespiratory fitness levels, and had no increased risk compared with non-statin users, according to a study in Obesity. Chinese researchers conducted a meta-analysis of 15 cohort studies and found that each 1-metabolic equivalent increase in cardiorespiratory fitness was tied to a 0.9 hazard ratio for type 2 diabetes.
Fitbit data showed US users took more than 26 trillion steps last year, walking more than 118.9 billion minutes and averaging 7,994 steps a day. The US ranks 33rd among countries worldwide in Fitbit steps walked, with Hong Kong residents at the top of the list with an average of 10,493 steps per day.
CMS Administrator Seema Verma said the agency is taking steps to address concerns regarding a new rule that requires hospitals to publish their chargemaster prices online after experts said the move won't help consumers very much. Verma said the rule is an "important first step" toward price transparency, and though the agency is currently soliciting feedback on how to further improve it, she encouraged hospitals to act now to make the data more useful.
The US spent $9,892 per person on health care in 2016, twice the amount spent in 2000 and 145% more than the Organization for Economic Cooperation and Development's median of $4,033, researchers reported in Health Affairs. The US spent more on health care than any other developed nation -- more than twice as much as Canada -- but had less access to care than other OECD countries, the report found.
