Model may help explain why women experience orgasms

Why females have orgasm has puzzled biologists, anthropologists, and philosophers for over 2000 years. While male orgasm has a clear reproductive function, as it is coupled to sperm transfer, no such function has been identified for female orgasm.

Study examines different types of surgery for kidney cancer

For completely endophytic kidney tumors, which grow inward, both open partial nephrectomy (OPN) and robotic partial nephrectomy (RPN) led to excellent patient outcomes in a recent study.

Study finds no link between sleep apnea and joint pain

Consistent with previous reports, poor sleep quality was linked with joint pain in a recent Arthritis Care & Research study of the general population, but the study found no association between obstructive sleep apnea and pain or daytime sleepiness. This lack of association between pain and sleep apnea is surprising given the established link between pain and poor sleep quality.

Sibling competition helped guide dispersal in pre-industrial populations

Researchers who examined family genealogies from Finland found that the presence of same-sex elder siblings increased the probability that people would disperse to new lands, whereas having opposite-sex siblings had less influence.

Gastrointestinal disorders involve both brain-to-gut and gut-to-brain pathways

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 and Wiley Announce Publishing Partnership

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.

Surgical expenses cause financial catastrophe for millions each year

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.

Beware of antioxidants, warns scientific review

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.

Hard-to-treat hypertension may jeopardize sleep apnea patients’ heart health

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.

High fat diet improves cartilage repair in mice

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.

Liver diseases exhibit differing patterns in ethnic minorities

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.

Modified rye bread helps patients with irritable bowel syndrome

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.

Research examines how to optimize nanoparticles for efficient drug delivery

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.

Risk of low blood sugar differs among similar diabetes drugs

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.

Soy-based protein boosts hunger hormone and stimulates appetite

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.

Study reveals new link between periodontal and cerebrovascular diseases

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.
