A University of Massachusetts Amherst researcher will examine the role of cumulative psychosocial stress – as well as race, ethnicity and gender – among U.S. military personnel to gauge their impact on cardiovascular health and healthcare utilization.
The study is funded with a $1 million grant from the Defense Health Agency, part of the Department of Defense (DoD). The findings will help the military develop programs for health promotion and health readiness for active duty and Reserve/National Guard personnel.
“One of the priorities of the Defense Health Agency is informing health promotion efforts for service members’ readiness and well-being,” says lead investigator Daniel López-Cevallos, associate professor of community health education in the School of Public Health and Health Sciences. “The strength of our study is that we are able to look at child abuse and neglect, bias and discrimination, and military stressors associated with health outcomes. We will be able to assess both the overall stress burden, as well as identify specific stressors that can affect heart health of U.S. service members.”
López-Cevallos is collaborating with Sheila Castañeda, a research epidemiologist in the Deployment Health Department at the Naval Health Research Center and deputy principal investigator of the Millenium Cohort Study. This cohort is the largest and longest-running prospective health study in U.S. military history, with more than 260,000 service members enrolled since 2001. The study is designed to examine the effects of military service on long-term health outcomes of service members and veterans.
The researchers will analyze survey data and DoD administrative and healthcare records from more than 58,000 military personnel who enrolled in the study in 2020-2021. Those participants were surveyed about adverse childhood experiences, experiences of hazing, bullying and discrimination, combat experiences, health diagnoses and other stressful life events.
“Previous epidemiological research indicates social determinants of health, such as increased exposure to stress, may contribute to cardiovascular disease disparities among certain racial and ethnic civilian groups,” Castañeda says. “Our study will determine the role of cumulative stress on heart health among service members in hopes of determining targets for integrated prevention efforts.”
In addition to measuring the associations between various stressors and cardiovascular health, López-Cevallos and Castañeda will look at the moderating effects of protective factors – such as post-traumatic growth, social support, unit cohesion and military satisfaction – on the relationship between cumulative psychosocial stress and health outcomes.
“One of the things we’re able to do in this study is to look at the cumulative or synergistic effects of experiencing multiple, both acute and chronic, stressors,” López-Cevallos says. “There is little research that has looked at disparities by gender and among racial and ethnic groups within the military.”
The researchers will use the American Heart Association’s Life’s Essential 8, which are key measures of cardiovascular health, in their analysis. They include health behaviors, such as eating and sleeping well and not using tobacco, and health factors, such as blood pressure, cholesterol, diabetes and body mass index.
“We will look at the aggregate levels of stress of these service members and then also get more specific to tease out individual stressors, such as adverse childhood experiences or experiences with harassment and discrimination. Then we can recommend areas of focus within the military to inform programmatic and policy priorities,” López-Cevallos says.
Another goal is to effect better cardiovascular outcomes and reduce healthcare system burdens by addressing the psychosocial stressors. “The theory here is to tackle those upstream factors that would otherwise erode health outcomes and also increase utilization of more complex health services,” he adds.

The biomarker human neutrophil lipocalin HNL, which was previously shown to be a useful indicator of bacterial infections, may also in the form of Dimeric HNL be used to effectively monitor the success of antibiotic treatment in sepsis. The first promising results in this regard were published in 2019 and now the research group has confirmed these results in a larger study. The study is published in the journal PLOS ONE.
Sepsis, the costliest disease to health care, is a life-threatening condition with high mortality if not diagnosed and ...
November 8, 2024, CLEVELAND: Cleveland Clinic researchers are presenting updated findings from their novel study of a vaccine aimed at preventing triple-negative breast cancer, the most aggressive and lethal form of the disease.
The study team found that the investigational vaccine was generally well tolerated and produced an immune response in most patients. The team described the side effects of the vaccine, showed the highest tolerated dose to date, and presented the immunologic effects of the vaccine. Findings are being presented at the Society for Immunotherapy of Cancer Annual Meeting.
Launched in 2021 and funded by the U.S. Department of Defense, the ongoing ...

Tool use isn’t unique to humans. Chimpanzees use sticks as tools. Dolphins, crows, and elephants are known for their tool-use abilities, too. Now a report in the Cell Press journal Current Biology on November 8, 2024, highlights elephants’ remarkable skill in using a hose as a flexible shower head. As an unexpected bonus, researchers say they also have evidence that a fellow elephant knows how to turn the water off, perhaps as a kind of “prank.”
“Elephants are amazing with hoses,” says Michael Brecht ...
When people have an audience watching them, it can change their performance for better or worse. Now, researchers reporting in the Cell Press journal iScience on November 8 have found that chimpanzees’ performance on computer tasks is influenced by the number of people watching them. The findings suggest that this “audience effect” predates the development of reputation-based human societies, the researchers say.
“It was very surprising to find that chimpanzees are affected in their task performance by ...

Researchers from Mass General Brigham are leveraging artificial intelligence to help identify the signs of long COVID, track how different symptoms manifest over time, and eliminate alternative explanations for patients’ symptoms.
The new approach suggests that 22.8% of the population experience the symptoms of long COVID, a figure that may paint a more realistic picture of the pandemic’s long-term toll.
Through analyzing a patient’s history over time, this new AI tool ...
About The Study: In this time-series study, heat waves were associated with increased adverse health events among dually eligible individuals 65 years and older. Without adaptation strategies to address the health-related impacts of heat, dually eligible individuals are increasingly likely to face adverse outcomes.

About The Study: In this cross-sectional study of U.S. patients seeking abortion, many individuals and their households were estimated to incur catastrophic health expenditures, particularly those traveling from out of state. The financial and psychological burdens of abortion seeking have likely worsened after the Dobbs decision, as more people need to cross state lines to reach abortion care. The findings suggest expansion of insurance coverage to ensure equitable access to abortion care, irrespective of people’s state of residence, ...
About The Study: In this cross-sectional study of pregnancy-associated homicide rates, barriers to divorce were associated with higher homicide rates and access to reproductive health care was associated with lower homicide rates. This study highlights the association between state legislation and pregnancy-associated homicide in the U.S., which is important information for policymakers.

Liver diseases, both acute and chronic, continue to pose significant clinical challenges due to high morbidity and mortality rates. Acute liver injury (ALI) caused by acetaminophen (APAP) overdose, hepatic ischemia-reperfusion injury (HIRI), and chronic conditions like nonalcoholic fatty liver disease (NAFLD) and alcohol-associated liver disease (ALD) are influenced by HMGB1-mediated pathways. HMGB1 is released from injured or necrotic liver cells and triggers inflammatory responses. Its circulating levels have been associated with disease severity in liver conditions, marking ...
