(Press-News.org) DARIEN, IL – A new study suggests that your level of sleepiness or alertness during the day may be related to the type of food that you eat.
Results show that higher fat consumption was associated with increased objective daytime sleepiness, while higher carbohydrate intake was associated with increased alertness. There was no relationship between protein consumption and sleepiness or alertness. These findings were independent of the subjects' gender, age, and body mass index as well as the total amount of sleep they were getting and their total caloric intake.
"Increased fat consumption has an acute adverse effect on alertness of otherwise healthy, non-obese adults," said principal investigator Alexandros Vgontzas, MD, professor of psychiatry at the Penn State College of Medicine in Hershey, Pa.
The research abstract was published recently in an online supplement of the journal Sleep, and Vgontzas will present the findings Tuesday, June 4, in Baltimore, Md., at SLEEP 2013, the 27th annual meeting of the Associated Professional Sleep Societies LLC.
The study group comprised 31 healthy, non-obese normal sleepers without sleep apnea, ranging in age from 18-65 years, who spent four consecutive nights in a sleep lab. On the fourth day objective sleepiness was assessed with the Multiple Sleep Latency Test (MSLT), and meals were provided five times to assess diet.
According to the authors, previous studies had found that diet composition affects subjective sleepiness. The current study adds to this body of research by showing a similar association between diet and objective sleepiness.
"Excessive daytime sleepiness and fatigue are very prevalent in the modern world and on the rise," said Vgontzas. "It appears that a diet high in fat decreases alertness acutely, and this may have an impact on an individual's ability to function and also public safety."

A joint venture of the American Academy of Sleep Medicine and the Sleep Research Society, the annual SLEEP meeting brings together an international body of more than 5,500 leading clinicians and scientists in the fields of sleep medicine and sleep research. At SLEEP 2013 (http://www.sleepmeeting.org) more than 1,300 research abstract presentations will showcase new findings that contribute to the understanding of sleep and the effective diagnosis and treatment of sleep disorders such as insomnia, narcolepsy and sleep apnea.
The American Academy of Sleep Medicine considers sleep disorders an illness that has reached epidemic proportions. Board-certified sleep medicine physicians in an AASM-accredited sleep center provide effective treatment.

DARIEN, IL – A new study suggests that regularity of bedtime prior to initiation of continuous positive airway pressure (CPAP) therapy is an important factor that may influence treatment compliance in adults with obstructive sleep apnea (OSA).
Results show that bedtime variability was a significant predictor of CPAP adherence, which was defined as four or more hours of treatment use per night. The odds of one-month CPAP non-adherence were 3.7 times greater for every one unit increase in habitual, or pre-treatment, bedtime variability.
"Long-term use of CPAP, such as ...

Boston (May 7, 2013) – The first successful cornea transplant with donor endothelial tissue preloaded by an eye bank has been performed at Massachusetts Eye and Ear in Boston, Mass. Roberto Pineda II, M.D., Director of the Refractive Surgery Service at Mass. Eye and Ear, and an Associate Professor of Ophthalmology at Harvard Medical School, recently performed the groundbreaking transplant.
Dr. Pineda performed the surgery utilizing donor endothelial tissue that was prepared and pre-loaded into EndoGlide™ (Angiotech Pharmaceuticals, Inc.) cartridges at the Lions Eye Institute ...
WASHINGTON, May 7, 2013 – From New York City's Central Park to Golden Gate Park in San Francisco, America's urban forests store an estimated 708 million tons of carbon, an environmental service with an estimated value of $50 billion, according to a recent U.S. Forest Service study.
Annual net carbon uptake by these trees is estimated at 21 million tons and $1.5 billion in economic benefit.
In the study published recently in the journal Environmental Pollution, Dave Nowak, a research forester with the U.S. Forest Service's Northern Research Station, and his colleagues ...
(PHILADELPHIA) An international group of investigators, led by researchers at Thomas Jefferson University's Kimmel Cancer Center, have solved the mystery of why a substantial percentage of castrate-resistant metastatic prostate cancer cells contain abnormally high levels of the pro-growth protein Stat5. They discovered that the gene that makes the protein is amplified — duplicated many times over — in these cancer cells, which allows them to produce excess amounts of the oncogenic protein.
The study, reported in the May 7 issue of the American Journal of Pathology, found ...
Enzymes could break down cell walls faster – leading to less expensive biofuels for transportation – if two enzyme systems are brought together in an industrial setting, new research by the Energy Department's National Renewable Energy Laboratory suggests.
A paper on the breakthrough, "Fungal Cellulases and Complexed Cellulosomal Enzymes Exhibit Synergistic Mechanisms in Cellulose Deconstruction," appears in the current edition of Energy and Environmental Science. Co-authors include five scientists from NREL and one from the Weizmann Institute in Israel.

Researchers from the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have quantified the significant value that concentrating solar power (CSP) plants can add to an electric grid.
The NREL researchers evaluated the operational impacts of CSP systems with thermal energy storage within the California electric grid managed by the California Independent System Operator (CAISO). NREL used a commercial production cost model called PLEXOS to help plan system expansion, to evaluate aspects of system reliability, and to estimate fuel cost, emissions, and ...
ANN ARBOR, Mich. — It was a controversial move when a health insurer began requiring people who were obese to literally pay the price of not doing anything about their weight – but it worked, a new study finds.
When people had to choose between paying up to 20 percent more for health insurance or exercising more, the majority of enrollees met fitness goals one step at a time via an Internet-tracked walking program, according to a joint study by the University of Michigan Health System and Stanford University.
Researchers evaluated a group of people insured by Blue ...
A new study shows that pediatric nurse staffing ratios are significantly associated with hospital readmission for children with common medical and surgical conditions.
The study, led by a nurse scientist at Cincinnati Children's Hospital Medical Center, is believed to be the first to examine the extent to which hospital nurse staffing levels are related to pediatric readmissions. Publication of the study comes just weeks after the introduction of federal legislation that would mandate nurse staffing ratios across the country.
The study, published online in the journal ...
Researchers at Moffitt Cancer Center say identifying and selecting participants for phase II cancer clinical trials from a centralized warehouse of patient-donated biological data expedites participant accrual, reduces trial size, saves money, and may speed test drugs through the drug development pipeline.
Their study, which analyzed datasets from recent clinical trials conducted at Moffitt, was published online March 15 in Statistical Methods in Medical Research.
Launched at Moffitt in 2005, Total Cancer Care® is a comprehensive approach to cancer that enables physicians, ...
