(Press-News.org) Amsterdam, NL, 11 September 2014 – Patients with Parkinson's disease (PD) can experience difficulties with food preparation and ingestion, which could contribute to poor nutrition and place them at risk for malnourishment. Published studies have also suggested that PD is associated with low weight, however, few studies included control groups. A report published in the Journal of Parkinson's Disease counters this conclusion in patients with mild-to-moderate PD, finding that the incidence or risk of malnutrition is no different for patients with mild-to-moderate PD compared to healthy controls.
"To our knowledge, this is one of the few studies worldwide that includes matched controls," says lead author Seyed-Mohammad Fereshtehnejad, MD, MPH, of the Division of Clinical Geriatrics of the Department of Neurobiology, Care Sciences, and Society of the Karolinska Institute, Stockholm, Sweden, and the Firoozgar Clinical Research Development Center, Firoozgar Hospital, Iran University of Medical Sciences, Tehran. "The results of this study indicate the same nutritional status among mild-to-moderate PD patients compared with healthy controls."
Many factors could lead to poor nutrition in PD patients, including motor difficulties with swallowing and chewing (dysphagia), cutting, and bringing food to the mouth. PD-related constipation and depression can also dampen a patient's appetite and change dietary habits. Consequences of malnutrition include higher medical costs, lower quality of life, and increased risk of morbidity and mortality.
To determine if PD patients are malnourished, 143 Iranian mild-to-moderate PD patients and 145 age- and sex-matched healthy controls were enrolled in this study. Any PD patients suffering from other chronic conditions influencing nutritional state, such as hypertension or diabetes, were following special diets, or exhibiting cognitive impairment were excluded.
Nutritional status was evaluated using the Persian version of the Mini Nutritional Assessment (MNA) questionnaire. In 10-15 minute interviews, patients answered 18 questions about appetite, dietary matters, feeding, self-perception of health, nutrition and malnutrition and were assessed for body mass index (BMI), weight loss, and arm and calf circumference. The maximum score on the MNA is 30; scores of 24-30 signify healthy nutrition, 17-23.5 indicate risk for malnutrition, and END

African American women receive less breast reconstruction after mastectomy
2014-09-11
Dartmouth researchers have found that African American women are 55 percent less likely to receive breast reconstruction after mastectomy regardless of where they received their care. They report on their findings in "The influence of race/ethnicity and place of service on breast reconstruction for Medicare beneficiaries with mastectomy," recently published in SpringerPlus.
"We wanted to understand whether the racial disparity observed in breast reconstruction among women with breast cancer was related to where women received care, independent of race," said Tracy Onega, ...
Commensal bacteria help orchestrate immune response in lung
2014-09-11
Studies in mice demonstrate that signals from the bacteria that harmlessly—and often beneficially—inhabit the human gastrointestinal tract boost the immune system's ability to kill a major respiratory pathogen, Klebsiella pneumoniae, according to a paper published online ahead of print in the journal Infection and Immunity.
The research is yet another example of how important these "commensal" bacteria are to human health and physiology, says Thomas B. Clarke, of Imperial College London, UK, the lone author of this paper.
"Numerous studies have shown that changes ...
Researchers make scientific history with new cellular connection
2014-09-11
Researchers led by Dr. Helen McNeill at the Lunenfeld-Tanenbaum Research Institute have revealed an exciting and unusual biochemical connection. Their discovery has implications for diseases linked to mitochondria, which are the primary sources of energy production within our cells.
Dr. McNeill's team has an international reputation for their work in understanding how cells become organized into tissues and how growth is regulated during development. The group focuses on mutations in the fat (ft) gene. The protein product of this gene, called 'Fat', acts at the cell membrane ...
Primary care doctors reluctant to provide genetics assessment in routine care
2014-09-11
Ann Arbor, Mich. — Primary care providers report many challenges to integrating genetics services into routine primary care, according to research published today in Genetics in Medicine.
Medical genetics medicine has traditionally been used to identify and diagnose rare diseases, but in the last decade it has been increasingly helpful in determining patients at risk for genetically-based conditions who can benefit from preventive health care, says the study's senior author, Beth Tarini, M.D., M.S., F.A.A.P., assistant professor of pediatrics at the University of Michigan ...
Penn medicine study reveals profile of patients most likely to delay hospice enrollment
2014-09-11
One in six cancer patients enroll in hospice only during their last three days of life, according to a new study from a team from the Perelman School of Medicine at the University of Pennsylvania. Their findings, published online last month in the Journal of Clinical Oncology (JCO) also reveal a profile of patients who may be most at risk of these late admissions.
"Waiting until the final days of life to begin hospice can shortchange patients and their families – skipping over many benefits of hospice care and limiting the opportunity to improve patients' quality of ...
Study maps 15 years of carbon dioxide emissions on Earth
2014-09-11
TEMPE, Ariz. – World leaders face multiple barriers in their efforts to reach agreement on greenhouse gas emission policies. And, according to Arizona State University researchers, without globally consistent, independent emissions assessments, climate agreements will remain burdened by errors, self-reporting, and the inability to verify emissions progress.
Now, an international research team led by ASU scientists has developed a new approach to estimate CO2 emissions from burning fossil fuels — one that provides crucial information to policymakers. Called the "Fossil ...
Dartmouth research links genetic mutation and melanoma progression
2014-09-11
Dartmouth researchers have found that the genetic mutation BRAFV600E, frequently found in metastatic melanoma, not only secretes a protein that promotes the growth of melanoma tumor cells, but can also modify the network of normal cells around the tumor to support the disease's progression. Targeting this mutation with Vemurafenib reduces this interaction, and suggests possible new treatment options for melanoma therapy. They report on their findings in "BRAFV600E melanoma cells secrete factors that activate stromal fibroblasts and enhance tumourigenicity," which was recently ...
Ceramics don't have to be brittle

Imagine a balloon that could float without using any lighter-than-air gas. Instead, it could simply have all of its air sucked out while maintaining its filled shape. Such a vacuum balloon, which could help ease the world's current shortage of helium, can only be made if a new material existed that was strong enough to sustain the pressure generated by forcing out all that air while still being lightweight and flexible.
Caltech materials scientist Julia Greer and her colleagues are on the path to developing such a material and many others that possess unheard-of combinations ...
Scientists report first semiaquatic dinosaur, Spinosaurus
2014-09-11
WASHINGTON (Sept. 11, 2014)—Scientists today unveiled what appears to be the first truly semiaquatic dinosaur, Spinosaurus aegyptiacus. New fossils of the massive Cretaceous-era predator reveal it adapted to life in the water some 95 million years ago, providing the most compelling evidence to date of a dinosaur able to live and hunt in an aquatic environment. The fossils also indicate that Spinosaurus was the largest known predatory dinosaur to roam the Earth, measuring more than 9 feet longer than the world's largest Tyrannosaurus rex specimen. These findings, published ...
Malaria parasites sense and react to mosquito presence to increase transmission
2014-09-11
Many pathogens are transmitted by insect bites. The abundance of vectors (as the transmitting insects are called) depends on seasonal and other environmental fluctuations. An article published on September 11thin PLOS Pathogens demonstrates that Plasmodium parasites react to mosquitoes biting their hosts, and that the parasite responses increase transmission to the mosquito vector.
Sylvain Gandon, from the CNRS in Montpellier, France, and colleagues first studied the theoretical evolution of parasite evolution in a variable environment. Using a mathematical model, they ...
