Rosemont, Ill. – Physicians should recommend low to moderate levels of exercise to their pregnant patients, even if they have not exercised prior to pregnancy, states a report published in the August 2009 issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS). According to this review article, exercise can strengthen and improve overall musculoskeletal and physiologic health as well as pregnancy related symptoms. Exercise such as aerobics, impact and nonimpact activities, resistance training and swimming:

Heavy drinkers of beer and spirits face a much higher risk of developing cancer than the population at large, says a group of Montreal epidemiologists and cancer researchers. Their findings show that people in the highest consumption category increased their risk of developing oesophageal cancer sevenfold, colon cancer by 80% and even lung cancer by 50%.

Interventional radiology procedures are on the rise in developing countries and there is a significant need for optimization of these procedures to ensure patient safety. Many facilities in these countries lack the concept of patient dose estimation and dose management, putting patients at a higher risk of developing complications due to overexposure from radiation during interventional procedures, according to a study performed by the International Atomic Energy Agency in Vienna, Austria.

The use of digital mammography equipment alone is responsible for an increased number of breast cancers detected at a community-based mammography facility, according to a study performed at San Luis Diagnostic Center in San Luis Obispo, CA.

Children's after-school activities often consist of sedentary behavior such as watching television, but after-school programs that offer physical activity and healthy snacks could be the best place for children's health.

David Dzewaltowski, head of the department of kinesiology at Kansas State University, and other K-State researchers have found that quality after-school programs are an important contributor to children's physical activity.

Philadelphia, PA, 3 August 2009 – A new class of antibody drugs may provide a powerful new tool for the treatment of eye diseases in children, but specialists need to be alert for the possibility of serious side effects, according to an editorial in the August Journal of AAPOS (American Association for Pediatric Ophthalmology and Strabismus), published by Elsevier.

Chronic inflammatory lung diseases like chronic bronchitis and emphysema are a major global health problem, and the fourth leading cause of death and disability in developed countries, with smoking accounting for 90% of the risk for developing them. Work by scientists at the European Molecular Biology Laboratory (EMBL) and its Molecular Medicine Partnership Unit (MMPU) with the University of Heidelberg, Germany, has shed new light on the underlying disease process of emphysema using a technique which could in future be adapted for use in diagnosis.

Almost all organisms evolve from a single cell, a fertilised egg. In the first hours after fertilisation, the fate of its future development is determined. It is dictated by the separation of cells that will become sperm and ovules - germ cells-, from the remaining cells, which will be responsible for forming the body –organs and tissues -, and that comprise the somatic cell line.

Scientists at Leeds and Bradford have discovered a unique 'DNA signature' in human sperm, which may act as a key that unlocks an egg's fertility and triggers new life.

Drs David Miller and David Iles from the University of Leeds, in collaboration with Dr Martin Brinkworth at the University of Bradford, have found that sperm writes a DNA signature that can only be recognised by an egg from the same species. This enables fertilisation and may even explain how a species develops its own unique genetic identity.

Biomolecular computers, made of DNA and other biological molecules, only exist today in a few specialized labs, remote from the regular computer user. Nonetheless, Tom Ran and Shai Kaplan, research students in the lab of Prof. Ehud Shapiro of the Weizmann Institute's Biological Chemistry, and Computer Science and Applied Mathematics Departments have found a way to make these microscopic computing devices 'user friendly,' even while performing complex computations and answering complicated queries.

RESTON, Va.—A new study published in the August issue of The Journal of Nuclear Medicine shows that positron emission tomography (PET) is an important tool for depicting the extent of neuroblastoma in some patients, particularly for those in the early stages of the disease. Neuroblastoma accounts for six to ten percent of all childhood cancers in the United States and 15 percent of cancer deaths in children.

CHAPEL HILL, N.C. – One of the most bothersome symptoms of leukemia is extreme fatigue, and asking these patients to exercise doesn't sound like a way to help them feel better.

A new study from the University of North Carolina at Chapel Hill indicates that exercise may be a great way to do just that, combating the debilitating fatigue that these patients experience.

August 3, 2009 — (BRONX, NY) — Seven out of ten U.S. children have low levels of vitamin D, raising their risk of bone and heart disease, according to a study of over 6,000 children by researchers at Albert Einstein College of Medicine of Yeshiva University. The striking findings suggest that vitamin D deficiency could place millions of children at risk for high blood pressure and other risk factors for heart disease. The study is published today in the online version of Pediatrics.

Physical education (PE) in schools is one of the main tools used to increase physical activity and to prevent childhood obesity, and PE-related injuries are on the rise. Although increasing physical activity may reduce obesity, it may also increase the risk of injury. While recognizing that PE classes and physical activity are important components in combating obesity, parents and school administrators should remain vigilant for injuries.

DALLAS – Aug. 3, 2009 – The new anti-wrinkle facial filler Dysport, which could be used as an alternative to Botox, noticeably reduced frown lines between the eyes, according to users and independent reviewers in a study involving plastic surgeons at UT Southwestern Medical Center.
