Delay in diagnosis of menopause-like condition in young women linked to low bone density

Women and young girls who experience delays in diagnosing a premature, menopause-like condition face increased risk of low bone density, according to new research by scientists at the National Institutes of Health. A delay in diagnosing the condition, called primary ovarian insufficiency, may make women more susceptible to osteoporosis and fractures later in life, the researchers concluded.

Frank, Dodd, Grassley speak their minds

Sen. Charles Grassley, R-Iowa, remains on the fence about several provisions in a Democratic plan, The Washington Post reports: "Winning over the Senate Finance Committee's ranking Republican would represent a major coup for Democrats and a rare defection from the GOP party line for Grassley, a populist at heart but a loyal Republican according to his voting record.

Texas "medical home" provides personal and coordinated health care

The Houston Chronicle reports on a medical philosophy that focuses on providing coordinated care and personal care to older patients, mostly indigent seniors. The paper examines Select Senior Clinic, a Texas facility that ascribes to the medical home concept.

New theory for global diabetes epidemic

A new "fertility first" hypothesis published this week by a group of international experts in the American Journal of Human Biology, proposes that the global epidemic of Type 2 diabetes has its origins in the struggle, over millennia, to sustain human fertility in environments defined by famine.

Omega-3 fatty acids may protect against progression of age-related macular degeneration

Omega-3 fatty acids found in fatty fish such as tuna and salmon may protect against progression of age-related macular degeneration (AMD), but the benefits appear to depend on the stage of disease and whether certain supplements are taken, report researchers at the Laboratory for Nutrition and Vision Research (LNVR), Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University.

Young adults with poor fitness levels on road to diabetes in middle age

Most healthy 25 year olds don't stay up at night worrying whether they are going to develop diabetes in middle age. The disease is not on their radar, and middle age is a lifetime away.

Scientists edit genes in human stem cells

Researchers at the Johns Hopkins School of Medicine have successfully edited the genome of human- induced pluripotent stem cells, making possible the future development of patient-specific stem cell therapies. Reporting this week in Cell Stem Cell, the team altered a gene responsible for causing the rare blood disease paroxysmal nocturnal hemoglobinuria, or PNH, establishing for the first time a useful system to learn more about the disease.

Obesity may reduce brain gray matter in postmenopausal women

Results from a small study of postmenopausal women suggest that obesity might relate to a reduced volume of gray matter in the brain. However, whether the results have relevance in a woman's day-to-day life is unclear.

Gout gene discovered

Having partnered last year with an international team that surveyed the genomes of 12,000 individuals to find a genetic cause for gout, Johns Hopkins scientists now have shown that the malfunctioning gene they helped uncover can lead to high concentrations of blood urate that forms crystals in joint tissue, causing inflammation and pain - the hallmark of this disease.

Rapid prototyping of new tissues and organs

A more effective way to build plastic scaffolds on which new tissues and even whole organs might be grown in the laboratory is being developed by an international collaboration between teams in Portugal and the UK.

Antibiotics diminish diversity of helpful gutmicrobes

It's common knowledge that a protective navy of bacteria normally floats in our intestinal tracts. Antibiotics at least temporarily disturb the normal balance. But it's unclear which antibiotics are the most disruptive, and if the full array of "good bacteria" return promptly or remain altered for some time.

Fallopian tubes: a new source of multipotent adult mesenchymal stem cells

Human tissues normally discarded after surgical procedures could be a rich additional source of stem cells for regenerative medicine. New research from BioMed Central's open access Journal of Translational Medicine shows for the first time that human fallopian tubes are abundant in mesenchymal stem cells which have the potential of becoming a variety of cell types.

Whole-genome searches unlock secrets of a childhood cancer

Two new studies from The Children's Hospital of Philadelphia advance the search for genetic events that result in neuroblastoma, a puzzling, often-deadly type of childhood cancer.

Research uncovers clues to the development of cancers in AIDS patients

In a series of recently-published articles, a research team from the University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center has uncovered clues to the development of cancers in AIDS patients.

Bariatric surgery raises kidney stone risk

The most popular type of gastric bypass surgery appears to nearly double the chance that a patient will develop kidney stones, despite earlier assumptions that it would not, Johns Hopkins doctors report in a new study. The overall risk, however, remains fairly small at about 8 percent.

Genome-wide map shows precisely where microRNAs do their work

MicroRNAs are the newest kid on the genetic block. By regulating the unzipping of genetic information, these tiny molecules have set the scientific world alight with such wide-ranging applications as onions that can't make you cry and therapeutic potential for new treatments for viral infections, cancer and degenerative diseases. But the question remains: How do they work?
