Researchers say they have developed a simple blood test that can spot biomarkers associated with bipolar disorder, potentially easing diagnosis. For the study, British researchers used both an online psychiatric assessment and a blood test to diagnose the condition. Many patients had previously been misdiagnosed with major depressive disorder. “People with bipolar disorder will experience periods of low mood and periods of very high mood or mania,” said first author Jakub Tomasik, a senior research associate at the University of Cambridge. “But patients will often only see a doctor when they’re experiencing low mood, which is why bipolar disorder frequently gets misdiagnosed as major depressive disorder,” he said in a university news release. On its own, the blood test could diagnose up to 30% of patients, researchers said. It was even more effective when combined with a digital mental health assessment. While still a “proof of concept” study, the blood test could eventually complement existing diagnostic tools, the authors said. It could also help researchers understand the biological origins of mental health conditions. “When someone with bipolar disorder is experiencing a period of low mood, to a physician, it can look very similar to someone with major depressive disorder,” said study leader Dr. Sabine Bahn, a professor of neurotechnology at the University of Cambridge. “However, the two conditions need to be treated differently: if someone…  read on >  read on >

Health workers are experiencing ever-increasing levels of harassment and burnout in the wake of the pandemic, a new federal survey has found. Reports of harassment on the job more than doubled during the pandemic years, and nearly half of health care workers often experience feelings of burnout, according to survey results published Oct. 24 in a new Vital Signs report from the U.S. Centers for Disease Control and Prevention. The survey is the first to describe in detail the mental health crisis among health care workers that first developed during the pandemic, federal officials said. “To label our current and longstanding challenge a crisis is an understatement,” said study senior author Dr. Casey Chosewood, director of the Office for Total Worker Health at the CDC’s National Institute for Occupational Safety and Health (NIOSH). “Many of our nation’s health care systems are at their breaking point,” Chosewood continued. “Staffing crises, lack of supportive leadership, long hours of work, and excessive demands and inflexibility in our nation’s health systems all must be addressed. We’re calling on employers to take this information to heart and take immediate preventive action.” The findings came from a survey on workplace quality that’s conducted on a regular basis by NIOSH. More than 13% of health workers said they had been harassed at work in 2022, compared with 6% in 2018 — before…  read on >  read on >

Older adults who live in distressed or disadvantaged communities are less likely to attend cardiac rehabilitation after common heart procedures, new research shows. The study looked at Medicare beneficiaries’ attendance at these medically supervised exercise and education programs after coronary revascularization between 2016 and 2018. Coronary revascularization includes procedures to improve blood flow to the heart, and can involve bypass surgery or receiving a stent to keep arteries open, according to the American College of Cardiology. The authors identified disadvantaged communities using a tool called the Distressed Community Index. It analyzes economic well-being and social determinants of health, such as educational disparities and poverty rate. In all, only 26% of patients from distressed communities use cardiac rehab, the research showed. That compared to 46% of patients from wealthier areas. No matter where they lived, any patient who attended cardiac rehab had a reduced risk of premature death, hospitalization and heart attack, the study found. “Addressing barriers to participation in cardiac rehabilitation in distressed communities may improve outcomes for these patients and reduce longstanding disparities in such outcomes,” said first author Michael Thompson, an assistant professor of cardiac surgery at the University of Michigan Medical School. “While some individuals who face geographic barriers to participation may benefit from transportation services or virtual options for cardiac rehab, there is a critical need to address socioeconomic barriers that…  read on >  read on >

The U.S. Environmental Protection Agency (EPA) proposes to ban a cancer-causing chemical commonly used as a furniture cleaner and degreaser. The ban would prohibit most uses of trichloroethylene (TCE) within one year. Limited remaining commercial and industrial uses would be phased out over a longer period and would require stringent worker protections. “Today, EPA is taking a vital step in our efforts to advance President Biden’s Cancer Moonshot and protect people from cancer and other serious health risks,” said EPA Deputy Administrator Janet McCabe. “The science is loud and clear on TCE. It is a dangerous toxic chemical and proposing to ban it will protect families, workers, and communities,” McCabe said in an agency news release. In addition to liver and kidney cancer, health risks associated with the toxin include disruption of the nervous and reproductive systems, and damage to fetal development, the EPA said. TCE is used in cleaning and furniture care products, degreasers, brake cleaners, and tire repair sealants. The EPA says safer alternatives exist. The proposal was made under the Toxic Substances Control Act. It would ban manufacturing, processing and distributing TCE for any use. “TCE has left a toxic legacy in communities across America. Today, EPA is taking a major step to protect people from exposure to this cancer-causing chemical,” said Michal Freedhoff, assistant administrator for the Office of Chemical Safety…  read on >  read on >
