World Humanitarian Day: WHO calls for protection of health workers in conflicts, disasters

Posted on Aug 19, 2014 7:18:11 AM

World Humanitarian Day

 As major emergencies around the globe increase in scale, complexity and frequency, the World Health Organization is calling for an end to the targeting of health workers in conflicts and other humanitarian crises, which represent a breach of the fundamental right to health.

World Humanitarian Day, celebrated every 19 August, WHO will draw attention to the continued trend of attacks on health care workers, hospitals, clinics and ambulances in Syria, Gaza, Central African Republic, Iraq, South Sudan and other areas.

Threats and harassment of health workers in West African countries have also been a worrying element of the Ebola Virus Disease outbreak. These professionals are taking personal risks to provide critical medical care, but have been threatened, shunned and stigmatized.

“Doctors, nurses and other health workers must be allowed to carry out their life–saving humanitarian work free of threat of violence and insecurity,” says Dr. Margaret Chan, WHO Director–General.

Dr. Richard Brennan, Director of WHO’s Department of Emergency Risk Management and Humanitarian Response, adds: “Assaults on health workers and facilities seriously affect access to health care, depriving patients of treatment and interrupting measures to prevent and control contagious diseases. WHO has a specific mandate to protect the human right to health, especially for people affected by humanitarian emergencies.”

While the adverse impacts of attacks on health care have been well documented in conflicts such as Syria and South Sudan, Gaza, health workers are also being prevented from carrying out their essential work outside of war–zones. In Pakistan and Nigeria, polio vaccinators, most of them female, have been specifically targeted.

As part of its lead role in coordinating the health response to international emergencies, WHO is working with partners to better document, prevent and respond to such incidents. Protecting those who care for the sick and vulnerable in the world’s most difficult circumstances is one of the most pressing responsibilities of the international community.


 

 

'Shape-shifting' material could help reconstruct faces

Posted on Aug 14, 2014 7:24:32 AM

surgery Researchers reported that they have developed a “self–fitting” material that expands with warm salt water to precisely fill bone defects, and also acts as a scaffold for new bone growth. The team described their approach in one of nearly 12,000 presentations at the 248th National Meeting & Exposition of the American Chemical Society (ACS).

To develop a material, Grunlan and her colleagues at Texas A&M University made a shape–memory polymer (SMP) that molds itself precisely to the shape of the bone defect without being brittle. It also supports the growth of new bone tissue. SMPs are materials whose geometry changes in response to heat. The team made a porous SMP foam by linking together molecules of poly(epsilon–caprolactone), an elastic, biodegradable substance that is already used in some medical implants. The resulting material resembled a stiff sponge, with many interconnected pores to allow bone cells to migrate in and grow.

 

Upon heating to 140 degrees Fahrenheit, the SMP becomes very soft and malleable. So, during surgery to repair a bone defect, a surgeon could warm the SMP to that temperature and fill in the defect with the softened material. Then, as the SMP is cooled to body temperature (98.6 degrees Fahrenheit), it would resume its former stiff texture and “lock” into place. The researchers also coated the SMPs with polydopamine, a sticky substance that helps lock the polymer into place by inducing formation of a mineral that is found in bone. It may also help osteoblasts, the cells that produce bone, to adhere and spread throughout the polymer. The SMP is biodegradable, so that eventually the scaffold will disappear, leaving only new bone tissue behind.

A blood test for suicide? Alterations to a single gene could predict risk of suicide attempt

Posted on Aug 1, 2014 5:00:00 AM

July 31, 2014 source: Johns Hopkins Medicine

 

Johns Hopkins researchers say they have discovered a chemical alteration in a single human gene linked to stress reactions that, if confirmed in larger studies, could give doctors a simple blood test to reliably predict a person’s risk of attempting suicide.

The discovery, described online in The American Journal of Psychiatry, suggests that changes in a gene involved in the function of the brain’s response to stress hormones plays a significant role in turning what might otherwise be an unremarkable reaction to the strain of everyday life into suicidal thoughts and behaviors.

“Suicide is a major preventable public health problem, but we have been stymied in our prevention efforts because we have no consistent way to predict those who are at increased risk of killing themselves,” says study leader Zachary Kaminsky, PhD, an assistant professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine. “With a test like ours, we may be able to stem suicide rates by identifying those people and intervening early enough to head off a catastrophe.”

For his series of experiments, Kaminsky and his colleagues focused on a genetic mutation in a gene known as SKA2. By looking at brain samples from mentally ill and healthy people, the researchers found that in samples from people who had died by suicide, levels of SKA2 were significantly reduced.

Within this common mutation, they then found in some subjects an epigenetic modification that altered the way the SKA2 gene functioned without changing the gene’s underlying DNA sequence. The modification added chemicals called methyl groups to the gene. Higher levels of methylation were then found in the same study subjects who had killed themselves. The higher levels of methylation among suicide decedents were then replicated in two independent brain cohorts.

In another part of the study, the researchers tested three different sets of blood samples, the largest one involving 325 participants in the Johns Hopkins Center for Prevention Research Study found similar methylation increases at SKA2 in individuals with suicidal thoughts or attempts. They then designed a model analysis that predicted which of the participants were experiencing suicidal thoughts or had attempted suicide with 80% certainty. Those with more severe risk of suicide were predicted with 90% accuracy. In the youngest data set, they were able to identify with 96% accuracy whether or not a participant had attempted suicide, based on blood test results.

The SKA2 gene is expressed in the prefrontal cortex of the brain, which is involved in inhibiting negative thoughts and controlling impulsive behavior. SKA2 is specifically responsible for chaperoning stress hormone receptors into cells’ nuclei so they can do their job. If there isn’t enough SKA2, or it is altered in some way, the stress hormone receptor is unable to suppress the release of cortisol throughout the brain. Previous research has shown that such cortisol release is abnormal in people who attempt or die by suicide.

Kaminsky says a test based on these findings might best be used to predict future suicide attempts in those who are ill, to restrict lethal means or methods among those at risk, or to make decisions regarding the intensity of intervention approaches. He says that it might make sense for use in the military to test whether members have the gene mutation that makes them more vulnerable. Those at risk could be more closely monitored when they returned home after deployment. A test could also be useful in a psychiatric emergency room, he says, as part of a suicide risk assessment when doctors try to assess level of suicide risk. The test could be used in all sorts of safety assessment decisions like the need for hospitalization and closeness of monitoring.

Dual training may help physicians obtain leadership roles, greater career acceleration

Dual training may help physicians obtain leadership roles, greater career acceleration


social media and physiciansHow can physicians obtain the leadership roles and career acceleration they desire? Perhaps an MBA can help. Graduates with dual training increasingly pursue leadership roles and experience greater career acceleration. According to a new study from researchers at the Perelman School of Medicine and the Wharton School at the University of Pennsylvania, physician graduates from the MBA program in health care management at Penn’s Wharton School report that their dual training had a positive effect on their individual careers and professional lives. Study respondents reported such benefits as career acceleration, professional flexibility, and credibility in multidisciplinary domains. Aside from clinical practice, the MD was more often cited as providing professional credibility, whereas the 40 to 50 percent of respondents said the MBA conveyed leadership, management, and business skills. Respondents said that the combination of degrees helped to inform their overall business and medical perspectives, supply multidisciplinary experience, and improve communication between the medical and business worlds.
