Medical students highly associated with alcohol abuse

New Delhi: A team of US researchers has found that medical students, especially who are young, single and under high debt are twice as likely to abuse alcohol than their peers who are not attending medical school.

Burnout factors such as emotional exhaustion or feelings of depersonalization were highly associated with alcohol abuse or dependence among the medical students.

“Our findings clearly show there is reason for concern,” said Liselotte Dyrbye from Mayo Clinic in the US.

“We recommend institutions pursue a multifaceted solution to address related issues with burnout, the cost of medical education and alcohol abuse,” Dyrbye added in the paper published in the journal Academic Medicine.

The researchers surveyed 12,500 medical students and one-third of those responded. Approximately 1,400 of that subgroup experienced clinical alcohol abuse or dependence.

The results indicate three factors that were independently associated — a younger age than most peers in medical school, being unmarried and amount of educational debt.

No statistical difference was found between differing years of medical school or between men and women.

“In our paper we recommend wellness curricula for medical schools, identifying and remediating factors within the learning environment contributing to stress and removal of barriers to mental health services,” added first author Eric Jackson.(IANS)

Researchers Develop, New Adhesive Patch That Can Minimize Heart Attack Damage

For the research, published in Nature Biomedical Engineering, the team tested the patch with rats and showed that the patch could be effective in reducing post-heart attack damage.

Researchers have developed a new adhesive patch that could reduce the stretching of cardiac muscle following a heart attack.

Developed by a team of researchers from Brown University, US; Fudan University, China and Soochow University, China, the patch is made from a water-based hydrogel material and can be placed directly on the heart to prevent left ventricular remodelling — a stretching of the heart muscle.

A heart attack puts the cardiac muscle at a risk of stretching out that can reduce the functioning of the heart’s main pumping chamber.

“Part of the reason that it’s hard for the heart to recover after a heart attack is that it has to keep pumping,” said co-author Huajian Gao, a professor at Brown University.

“The idea here is to provide mechanical support for damaged tissue, which hopefully gives it a chance to heal,” he added.

The researchers said the patch, which costs “less than a penny”, has been optimised using a computer model of the heart to perfectly match the material’s mechanical properties.

“If the material is too hard or stiff, then you could confine the movement of the heart so that it can’t expand to the volume it needs to,” Gao said.

“But if the material is too soft, then it won’t provide enough support. So we needed some mechanical principles to guide us,” he pointed out.

For the research, published in Nature Biomedical Engineering, the team tested the patch with rats and showed that the patch could be effective in reducing post-heart attack damage.

“The patch provided nearly optimal mechanical supports after myocardial infarction (i.e. massive death of cardiomyocytes),” said co-author Ning Sun, a cardiology researcher at Fudan University.

“[It] maintained a better cardiac output and thus greatly reduced the overload of those remaining cardiomyocytes and adverse cardiac remodelling.”

“It remains to be seen if it will work in humans, but it’s very promising,” Gao said. (IANS)
