New research indicates that in patients with irritable bowel syndrome (IBS) or indigestion, there is a distinct brain-to-gut pathway, where psychological symptoms begin first, and separately a distinct gut-to-brain pathway, where gut symptoms start first.
The American Association of Physicists in Medicine (AAPM) and John Wiley and Sons Inc. announced today a publishing partnership for AAPM’s prestigious portfolio of scholarly journals in medical physics. With over 8,000 members globally, the AAPM is one of the largest and most highly regarded professional organizations for researchers and scientists working in medical physics and related fields.
According to an analysis of publicly available data from 186 countries, direct medical costs of surgery put an estimated 43.9 per cent of the world’s population at risk of financial catastrophe and between 30.8 and 57.0 per cent at risk of falling below national and international poverty lines.
The lay press and thousands of nutritional products warn of oxygen radicals or oxidative stress and suggest taking so-called antioxidants to prevent or cure disease. Professor Pietro Ghezzi at the Brighton and Sussex Medical School and Professor Harald Schmidt at the University of Maastricht have analyzed the evidence behind this. The result is a clear warning: do not take these supplements unless a clear deficiency is diagnosed by a healthcare professional.
In a study of patients with hypertension, those with resistant hypertension—meaning that their blood pressure remained elevated despite concurrent use of three antihypertensive agents of different classes—had a higher rate of sleep apnea (9.6%) than those without resistant hypertension (7.2%). Resistant hypertensive patients with sleep apnea had an increased risk of ischemic heart events and congestive heart failure compared with patients with sleep apnea and non-resistant hypertension. There were no differences in risk of stroke and premature death in patients with resistant versus non-resistant hypertension, however.
Obesity is a well-known risk factor for osteoarthritis, but its effects on cartilage repair are unknown. In a recent study in a mouse model of cartilage repair, a high fat diet and increased body weight did not negatively impair cartilage repair, and it could even accelerate it.
Chronic liver disease (CLD) and cirrhosis are serious liver conditions but little is known about how they affect ethnic minority populations in the United States. When researchers examined CLD and cirrhosis among different groups, they found that the prevalence of CLD ranged from 3.9 percent in African Americans and Native Hawaiians to 4.1 percent in whites, 6.7 percent in Latinos, and 6.9 percent in Japanese.
Patients with irritable bowel syndrome (IBS) are often concerned that certain foods may trigger or worsen their symptoms, which can include abdominal pain, diarrhea, or constipation. In a new study, patients who ate rye bread that was low in so-called “FODMAPs” (fermentable oligo- di- and mono-saccharides and polyols) experienced milder IBS symptoms than patients who ate normal rye bread.
Nanoparticles are being studied as drug delivery systems to treat a wide variety of diseases. New research delves into the physical properties of nanoparticles that are important for successfully delivering therapeutics within the body, with a primary focus on size. This is especially important as relatively subtle differences in size can affect cell uptake and determine the fate of nanoparticles once within cells.
Adding sulphonylureas (SUs) to metformin remains a commonly used strategy for treating type 2 diabetes, but individual SUs differ and may confer different risks of abnormally low blood sugar, or hypoglycemia. SUs—which include newer generation agents such as gliclazide, glipizide, glimepiride, and glibenclamide—stimulate the production of insulin in the pancreas and increase the effectiveness of insulin in the body.
Researchers have discovered a protein that stimulates secretion of ghrelin, an appetite-stimulating hormone produced in the stomach. When fed to mice, the protein, called soy-ghretropin, increased blood levels of ghrelin and boosted their appetite.
A new study has revealed a relationship between chronic periodontitis and lacunar infarct, two common diseases in the elderly. Chronic periodontitis is an inflammatory disease of the gums, whereas lacunar infarct is a type of cerebral small vessel disease that can lead to a stroke.
John Wiley and Sons Inc. announced today that it has been selected by the International Federation of Gynecology and Obstetrics (FIGO) as its publishing partner for its distinguished publication, the International Journal of Gynecology & Obstetrics (IJGO). This agreement, commencing in January 2017, will see the Journal move to the Wiley Online Library platform.
Consistently watching high levels of television during childhood and adolescence were linked with lower peak bone mass at age 20 years in a recent study.
In 2005, the National Institute for Health and Care Excellence (NICE) in England and Wales provided new guidance on the use of anti-osteoporosis therapies for the prevention of additional fractures in patients who had experienced osteoporotic fractures, which was followed by market authorization of a generic form of alendronic acid.
Researchers at several different US sites have found that less than one-third of 1% of patients infected with hepatitis B virus (HBV) get rid of the virus per year, and overall, only 1.2% of patients finally get rid of it.
Long-term use of antiepileptic drugs is a significant risk factor for vitamin D deficiency in children with epilepsy. A new Epilepsia study found that despite living in the tropics, a high proportion of Malaysian children with epilepsy are at risk of vitamin D deficiency.
Poor physical performance was linked with an increased risk of developing dementia in a study of individuals aged 90 and older who were followed for an average of 2.6 years.
Low educational level, low disposable income, being divorced or never married, and living in a single-person household all increase the risk of advanced stage penile cancer, according to new research.
A new article looks at how two recent developments, the Open Water Data Initiative, and the new National Water Center, have created a platform for the open sharing of water data in the United States.
