Baby-led weaning is feasible but could cause nutritional problems for minority of infants

Most babies can reach out for and eat finger food by six to eight months, according to a study in the January issue of Maternal and Child Nutrition.

However baby-led weaning - which advocates babies feeding themselves solid foods, rather than being spoon fed purees - could lead to nutritional problems for the small number of children who develop later than average.

First genetic test for predicting IVF success

January 11, 2011 — (BRONX, NY) — A researcher at Albert Einstein College of Medicine of Yeshiva University has helped to develop the first genetic blood test for predicting the chances that in vitro fertilization (IVF) will lead to a successful pregnancy. The test, reported in the online medical journal PLoS One, is based on the finding that different subtypes of the FMR1 gene (also known as the fragile X mental retardation gene) in potential mothers are associated with significantly different chances of conceiving with IVF.

Texas AM study finds courtship affects gene expression in flies

COLLEGE STATION, Jan. 11, 2011 – Biologists at Texas A&M University have made an important step toward understanding human mating behavior by showing that certain genes become activated in fruit flies when they interact with the opposite sex.

Measles virus, a weapon against cancer?

GALVESTON, Texas — When most people in the developed world think of measles, what comes to mind is only a dim memory of a vaccination at a pediatrician's office. But while childhood vaccination has virtually eliminated measles from North America and much of Europe, researchers remain interested in the virus.

Link between fracture prevention and treatment adherence not fully understood by patients

Newly released findings of a multinational survey conducted on behalf of the International Osteoporosis Foundation (IOF) show clear disparities between patients' and doctors' perceptions of osteoporosis and its management.

Biomedical breakthrough: Blood vessels for lab-grown tissues

Researchers from Rice University and Baylor College of Medicine (BCM) have broken one of the major roadblocks on the path to growing transplantable tissue in the lab: They've found a way to grow the blood vessels and capillaries needed to keep tissues alive.

The new research is available online and due to appear in the January issue of the journal Acta Biomaterialia.

Study finds more breaks from sitting are good for waistlines and hearts

It is becoming well accepted that, as well as too little exercise, too much sitting is bad for people's health. Now a new study has found that it is not just the length of time people spend sitting down that can make a difference, but also the number of breaks that they take while sitting at their desk or on their sofa. Plenty of breaks, even if they are as little as one minute, seem to be good for people's hearts and their waistlines.

Acne bug could be the cause of your infections

Previously, researchers thought the detection of P. acnes at the site of these infections was due to contamination from the skin. For example, an infection at a site within the body after surgery, could have been caused by bacteria transferred to an open wound from the skin during an operation. But recent research has contradicted this, suggesting P. acnes already within the body, may be the cause. Although it is often disregarded as a harmless bystander when found in blood and tissue swabs taken from patients, we should not rule out this bug in the diagnosis of disease.

DNA blood test can cut invasive testing for Down's syndrome by 98 percent

The blood test could mean that 98% of invasive procedures could be avoided, say the authors. The test uses the latest DNA technology to analyse genetic components in the mother's blood that indicate whether the foetus has Down's.

Down's syndrome or trisomy 21 occurs in around 1 in 800 births and older women are at higher risk.

Call for full access to Tamiflu trial data to allow for independent scrutiny

Tom Jefferson and colleagues from the Cochrane Group argue that the current system for assessing the safety and effectiveness of drugs, based on published trial data only, is "wholly inadequate" and "ethically dubious."

They propose a new approach that would allow in-depth scrutiny of the complete set of trial data for a new drug.

Their call comes after they reviewed the evidence for the antiviral drug oseltamivir (Tamiflu), and were unable to find sufficient published data to support the conclusion that oseltamivir reduces complications in healthy adults.

Behavioral therapy program reduces incontinence following radical prostatectomy

For men with incontinence for at least one year following radical prostatectomy, participation in a behavioral training program that included pelvic floor muscle training, bladder control strategies and fluid management, resulted in a significant reduction in the number of incontinence episodes, according to a study in the January 12 issue of JAMA. The researchers also found that the addition of biofeedback and pelvic floor electrical stimulation provided no additional benefit.

Priorities to reduce birth asphyxia focus on implementation

Joy Lawn from Saving Newborn Lives/Save the Children, South Africa, and an international group of colleagues used a systematic process developed by the Child Health Nutrition Research Initiative (CHNRI) to define and rank research options to reduce mortality from intrapartum-related neonatal deaths (birth asphyxia) by the year 2015.

Technique allows researchers to identify key maize genes for increased yield

ITHACA, N.Y. — Scientists have identified the genes related to leaf angle in corn (maize) – a key trait for planting crops closer together, which has led to an eight-fold increase in yield since the early 1900s. (Nature Genetics, Jan. 9, 2011.)

Shingles vaccine associated with 55 percent reduced risk of disease

PASADENA, Calif. (January 11, 2011) – Receiving the herpes zoster vaccine was associated with a 55 percent reduced risk of developing shingles, according to a Kaiser Permanente study of 300,000 people that appears in the current issue of the Journal of the American Medical Association.

Zoster vaccine associated with lower risk of shingles in older adults

Vaccination for herpes zoster, a painful rash commonly known as shingles, among a large group of older adults was associated with a reduced risk of this condition, regardless of age, race or the presence of chronic diseases, according to a study in the January 12 issue of JAMA.
