MRI improves diagnosis of microbleeding after brain injury in military personnel


MRI improves diagnosis of microbleeding after brain injury in military personnel
2015-09-15
(Press-News.org) OAK BROOK, Ill. - Imaging patients soon after traumatic brain injury (TBI) occurs can lead to better (more accurate) detection of cerebral microhemorrhages, or microbleeding on the brain, according to a study of military service members, published online in the journal Radiology.

Cerebral microhemorrhages occur as a direct result of TBI and can lead to severe secondary injuries such as brain swelling or stroke. The ability to monitor the evolution of microhemorrhages could provide important information regarding disease progression or recovery.

According to the Centers for Disease Control and Prevention's (CDC) National Center for Injury and Prevention Control, about 1.7 million people in the United States sustain TBI each year. Furthermore, the Institute of Medicine reports that 20 to 23 percent of military service members deployed to Afghanistan and Iraq have sustained TBI while serving.

"TBI is a large problem for our military service members and their families," said Dr. Gerard Riedy, M.D., Ph.D., chief of neuroimaging at the National Intrepid Center of Excellence at the Walter Reed National Military Medical Center in Bethesda, Md. "We found that many of those who have served and suffered this type of injury were not imaged until many, many months after injury occurred thus resulting in lower rates of cerebral microhemorrhage detection which delays treatment."

For the study, Dr. Riedy and colleagues used susceptibility-weighted imaging--an MRI technique that provides improved visibility of blood and is highly sensitive to hemorrhage--to evaluate 603 military service members with TBI. The median time from point of injury to imaging was 856 days. Of the 603 military service members who participated in the study, 7 percent were found to have at least one occurrence of cerebral microhemorrhage.

The patients were divided into four groups based on time since the injury occurred, ranging from less than three months to over a year. The results found that those who were imaged more than a year after the injury had a much lower occurrence of cerebral microhemorrhages than those who were scanned 12 months or fewer after TBI.

Cerebral microhemorrhage was identified in 24 percent of military personnel who were imaged within three months post-injury, compared to 5.2 percent of the patients who were imaged over a year later. The researchers attribute this to changes in iron deposits in the brain as time goes on, making it more difficult to detect microbleeding.

"Early characterization of cerebral microhemorrhages may help to explain clinical symptoms of acute TBI and identify the severity of brain damage," Dr. Riedy said. "We believe that having access to MRI in the field would facilitate early detection of TBI, thus providing timely treatment."

The study also supports previous claims that using susceptibility-weighted imaging to evaluate brain injury patients may be more effective than conventional MRI. In this study's capacity, using susceptibility-weighted imaging resulted in detecting significantly more microhemorrhages due to a higher spatial resolution and signal, with 77 percent of cerebral microhemorrhages appearing more evident through susceptibility-weighted imaging when compared to conventional MRI.

Effects of prenatal myelomeningocele closure on the need for a CSF shunt

2015-09-15
CHARLOTTESVILLE, VA (SEPTEMBER 15, 2015). Management of Myelomeningocele Study (MOMS) investigators analyzed updated data on the effects of prenatal myelomeningocele closure on the need for placement of a cerebrospinal fluid (CSF) shunt within the first 12 months of life. These researchers reaffirm the initial MOMS finding that prenatal repair of a myelomeningocele results in less need for a shunt at 12 months and introduce the new finding that prenatal repair reduces the need for shunt revision in those infants who do require shunt placement. The researchers also found ...

Link between air pollution, increased deaths and increased deaths from heart disease affirmed

2015-09-15
In what is believed to be the largest, most detailed study of its kind in the United States, scientists at NYU Langone Medical Center and elsewhere have confirmed that tiny chemical particles in the air we breathe are linked to an overall increase in risk of death. The researchers say this kind of air pollution involves particles so small they are invisible to the human eye (at less than one ten-thousandth of an inch in diameter, or no more than 2.5 micrometers across). In a report on the findings, published in the journal Environmental Health Perspectives online Sept. ...

'Our chairs are killing us,' say researchers

2015-09-15
Amsterdam, The Netherlands, September 15, 2015 -- Prolonged sitting time as well as reduced physical activity contribute to the prevalence of non-alcoholic fatty liver disease (NAFLD) in a study of middle-aged Koreans. These findings support the importance of both reducing time spent sitting and increasing physical activity, say researchers. Their results are published in the Journal of Hepatology. Physical activity is known to reduce the incidence and mortality of various chronic diseases. However, more than one half of the average person's waking day involves sedentary ...

Combining epigenetic therapies with immunotherapies likely to improve cancer patient outcomes

2015-09-15
PHILADELPHIA -- Recent data suggest that epigenetic therapies are likely to provide additional clinical benefit to cancer patients when rationally combined with immunotherapeutic drugs, according to a review published in Clinical Cancer Research, a journal of the American Association for Cancer Research. "The term epigenetics refers to the study of cellular changes in gene expression that are heritably transmitted during cell replication," said Michele Maio, MD, PhD, chair of medical oncology and immunotherapy, Ospedale Santa Maria alle Scotte, Istituto Toscano Tumori, ...

Video game warnings fall far short in rating tobacco content

2015-09-15
Video games are not adequately rated for tobacco content, according to a new UC San Francisco study that found video gamers are being widely exposed to tobacco imagery. The researchers concluded that a national ratings board set up more than 20 years ago is not a reliable source for learning whether video games contain tobacco imagery. The study will be published online September 14 in Tobacco Control. "Parents should stop relying on the ratings to screen for tobacco use in buying video games for their kids," said first author Susan Forsyth, a PhD candidate at ...

Heightened injury risk linked to shift length for emergency services clinicians

2015-09-15
Working shifts of 16 to 24 hours in length is linked to a 60% heightened risk of injury and illness among emergency services (EMS) clinicians, compared to shifts of 8-12 hours, finds research published online in Occupational & Environmental Medicine. This risk rises in tandem with shift length, the findings show. The nature of the job requires physical strength to lift and move patients, clear mental focus to deliver medical care in uniquely stressful and often chaotic situations, and sufficient alertness to drive safely, say the researchers. Yet EMS clinicians often ...

Widely used software doesn't note differences in care quality among hospital readmissions

2015-09-15
The 3M software program, increasingly used to make payments to US hospitals based on readmission rates, doesn't clearly distinguish differences in care quality--one of the key factors involved in readmission--between readmissions that are preventable and those that aren't, suggests research published online in BMJ Quality and Safety. The Centers for Medicare and Medicaid Services (CMS) posts data on 30 day readmissions for three common causes of hospital admissions: heart attack; heart failure; and pneumonia. Hospitals with high rates of readmissions are penalised ...

Study suggests improving blood sugar control could help prevent dementia in patients with type 2 diabetes

2015-09-15
A study of 350,000 patients with type 2 diabetes shows that those with poor blood sugar control have 50% higher risk of being admitted to hospital in future for dementia as those with good control. The research, which suggests improving blood sugar control could prevent many cases of dementia, is by Dr Aidin Rawshani, National Diabetes Register and Institute of Medicine, Gothenburg, Sweden, and colleagues, and is presented at this year's annual meeting of the European Association for the Study of Diabetes (EASD) in Stockholm. Evidence is growing that diabetes increases ...

Diabetic women at 34 percent higher risk of heart attack than diabetic men as they age

2015-09-15
New research presented at this year's annual meeting of the European Association for the Study of Diabetes in Stockholm shows that diabetic women are more at risk than diabetic men of having a heart attack and other complications as they age. The study is by Dr Giuseppe Seghieri, Regional Health Agency, Florence, Italy, and colleagues. Previous research has revealed that diabetic women have a higher risk of cardiovascular events than diabetic men, when compared with the respective non-diabetic counterparts. However, it is unclear when this risk begins or how long it ...

Studies covering 11 million patients show diabetic women around 40 percent more likely to suffer severe heart problems than diabetic men

2015-09-15
A systematic review and meta-analysis of 19 studies containing almost 11 million patients shows that diabetic women are around 40% more likely to suffer acute coronary syndromes (heart attack or angina) than diabetic men. The study is by Dr Xue Dong, the Affiliated ZhongDa Hospital of Southeast University, Nanjing, China, and colleagues, and is presented at this year's annual meeting of the European Association for the Study of Diabetes (EASD) in Stockholm. Diabetes is a strong risk factor for acute coronary syndrome, yet whether diabetes confers the same excess risk ...
