Potential link between assisted reproduction, autism: No link found

Potential link between assisted reproduction, autism: No link found

When prospective parents have trouble conceiving and decide to seek medical help, they typically experience more than a little anxiety and have a host of questions: What are the potential risks to the mother and the baby? What kinds of diseases or other problems are associated with assisted reproduction? And, is one of those problems autism Continue reading

Stillbirth gap closing between indigenous, non-indigenous women, shows Australian study

Stillbirth gap closing between indigenous, non-indigenous women, shows Australian study

The gap in stillbirth rates between indigenous and non-indigenous women in Queensland, Australia, is closing, however indigenous women are still at risk of stillbirth due to preventable causes, find researchers in a new study published in BJOG: An International Journal of Obstetrics and Gynaecology ( BJOG ).

Scientists call for investigation of mysterious cloud-like collections in cells

Scientists call for investigation of mysterious cloud-like collections in cells

About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don’t know what they do — even though these shifting cloud-like collections of proteins are believed to be crucial to the life of a cell, and therefore could offer a new approach to disease treatment. In the Journal of Cell Biology , two researchers are issuing a call to investigators from various backgrounds, from biophysics to cell biology, to focus their attention on the role of these formations — for which they coin a new unifying term “assemblages.” “I want to know what these assemblages are doing in Ewing sarcoma, the disease I concentrate on — and I would think all other researchers who study human biology would want to know their functions in both health and disease,” says Jeffrey Toretsky, MD, professor in the department of oncology and pediatrics at Georgetown Lombardi Comprehensive Cancer Center.

Avatars make the Internet sign to deaf people

Avatars make the Internet sign to deaf people

It is challenging for deaf people to learn a sound-based language, since they are physically not able to hear those sounds. Hence, most of them struggle with written language as well as with text reading and comprehension. Continue reading

Mouth bacteria can change its diet, supercomputers reveal

Mouth bacteria can change its diet, supercomputers reveal

Bacteria inside your mouth drastically change how they act when you’re diseased, according to research using supercomputers at the Texas Advanced Computing Center (TACC). Scientists say these surprising findings might lead to better ways to prevent or even reverse the gum disease periodontitis, diabetes, and Crohn’s disease. Marvin Whiteley, professor of molecular biosciences and director of the Center for Infectious Disease at The University of Texas at Austin, led the study published in April 2014 in the journal mBio .

Sleep deficiency and sleep medication use in astronauts

Sleep deficiency and sleep medication use in astronauts

In an extensive study of sleep monitoring and sleeping pill use in astronauts, researchers from Brigham and Women’s Hospital (BWH) Division of Sleep and Circadian Disorders, Harvard Medical School, and the University of Colorado found that astronauts suffer considerable sleep deficiency in the weeks leading up to and during space flight.

Powerful new system for classifying tumors revealed

Powerful new system for classifying tumors revealed

Cancers are classified primarily on the basis of where in the body the disease originates, as in lung cancer or breast cancer. According to a new study, however, one in ten cancer patients would be classified differently using a new classification system based on molecular subtypes instead of the current tissue-of-origin system.

Studying muscle function to treat heart failure

Studying muscle function to treat heart failure

Muscle physiologist Edward Debold at the University of Massachusetts Amherst’s School of Public Health and Health Sciences recently received a three-year, $198,000 grant from the American Heart Association to support studies to uncover the molecular mechanisms of skeletal muscle fatigue. The work will advance basic understanding of muscle function and should lead to new drug therapies for individuals with fatigue that greatly limits physical function and quality of life, including the 5.7 million Americans living with chronic heart failure Continue reading

Causes of death shifting in people with HIV

Causes of death shifting in people with HIV

HIV-positive adults in high income countries face a substantially reduced risk of death from AIDS-related causes, cardiovascular disease, and liver disease compared with a decade ago, according to a large international study published in The Lancet. The study which involved nearly 50,000 HIV-positive adults receiving care and antiretroviral therapy (ART) at more than 200 clinics across Europe, USA, and Australia found that overall death rates have almost halved since 1999, while deaths due to AIDS-related causes and cardiovascular disease have declined by around 65% and liver-related deaths by more than 50%. Although deaths from most causes declined over the study period, there was no reduction in death rates from non-AIDS cancers which remained stable over time (1.6 deaths per 1000 years 1999-2000 to 2.1 in 2009-2011) Continue reading

Four Lessons for Effective, Efficient Research in Health Care Settings

Four Lessons for Effective, Efficient Research in Health Care Settings

Thousands of studies take place every year in healthcare settings. A report published recently in the American Journal of Preventative Medicine describes how to do many of these studies more rapidly. By taking into account the real-world constraints of the systems in which providers deliver care and patients receive it, researchers can help speed results, cut costs, and increase chances that recommendations from their findings will be implemented.
