The study, which analyzed data from 2,494 cases in Germany, suggests that these medications may render some individuals more vulnerable to heat-related heart attacks.
A new Yale School of Public Health study emphasizes the importance of individual and population-level vaccination and boosting in controlling COVID-19 infections. The research shows that recent vaccinations significantly decrease an individual's risk of contracting COVID-19, but may not affect transmission length.
A new study published in the International Journal of Public Health found that testing people at the door or immediately before social mixing can significantly reduce COVID-19 transmission. The research suggests that testing on the day of an event or even 12 hours prior to arrival can effectively limit the spread of the virus.
A new study by Yale School of Public Health researchers found that COVID-19 vaccine protection against infection and severe illness is short-lived. The study suggests that booster shots are essential for maintaining long-term immunity and preventing breakthrough infections.
Researchers found that frequent, regular rapid antigen testing, combined with isolating those who test positive, can effectively suppress COVID outbreaks. The study suggests that testing every other day can be as effective as a 24-hour turnaround PCR test in reducing transmission.
The study recommends a multi-layered approach to mitigate the impact of gas and oil production operations on communities and the environment. Reducing new drilling and properly discontinuing active and inactive oil and gas wells is considered most effective in eliminating environmental stressors.
A Yale study found that living through extended droughts increases diarrhea risk among children, even with adequate sanitation. Climate change is projected to exacerbate this issue, highlighting the need for improved water and hygiene infrastructure.
A machine learning model has been developed to predict TB resistance to fluoroquinolones, which could speed up treatment. The model uses demographic and clinical factors to estimate the probability of resistance, allowing clinicians to optimize treatment regimens before test results are available.
Experts recommend an integrated approach to reduce the impacts of fracking on wildlife and human health. This includes protecting vulnerable populations, ecosystems, and regions underrepresented in decision-making processes.
A study by Yale researchers found a relative of the Lyme disease bacteria, Borrelia miyamotoi, in human blood samples across New England. The presence of this tiny species, transmitted by deer ticks, suggests that physicians should be aware of its potential for causing meningoencephalitis and relapsing fevers.
Researchers at Yale have identified a remdesivir-resistant variant of the SARS-CoV-2 virus in an immunocompromised patient. The discovery raises concerns about drug resistance in COVID-19 patients, particularly those with weakened immune systems.
A novel analysis applied to anonymous location information from mobile devices helped health officials stem community outbreaks and allocate testing resources. The study successfully predicted initial waves of cases, localized outbreaks, and areas of high transmission risk.
The Yale School of Public Health is partnering with Tevogen Bio to expand its regulatory sciences program, with financial support from the biotech company. The goal is to prepare talented leaders for a rapidly growing field that focuses on product regulation and assessment.
The fellowship program aims to recruit and train skilled data scientists to advance care through precision medicine. Yale's robust computational resources, biomedical data repositories, and faculty expertise will be available to fellows.
A new Yale School of Public Health study found that 31% of days featured positive experiences and 11% had negative experiences related to racial and sexual identity. The findings suggest that spaces catering to the Black LGBQ+ community can improve well-being.
A study from Yale School of Public Health found that higher rates of e-cigarette and marijuana use were associated with fewer vaping-related lung injuries. The study suggests that well-established markets for these substances may have crowded out the use of riskier, informally sourced e-liquids that drove the outbreak.
A new study by the Yale School of Public Health found that approximately 30% of women and 17% of men in the US have experienced a major depressive episode. The study also showed that mental health programs can benefit a larger segment of the population than previously thought.
Researchers found death records of LGBTQ youth who died by suicide were more likely to mention bullying as a factor than non-LGBTQ peers. Bullying was identified as a major risk factor for suicidal thoughts and behaviors among LGBTQ youth.
A new study led by the Yale School of Public Health found that the coronavirus pandemic is likely to have profound short- and long-term consequences for physical and mental health, particularly for vulnerable populations. The research showed that exposures common to the current pandemic are strongly associated with posttraumatic stress...
A new study found that China's countrywide ban on traffic mobility during the pandemic greatly limited automobile emissions and sharply reduced severe air pollution. This led to an estimated 12,125 avoided premature deaths compared to lives lost from the pandemic, with two-thirds of these being from cardiovascular diseases.
A new HIV prevention drug, emtricitabine/tenofovir alafenamide (F/TAF), has been met with criticism for its high cost and limited benefits compared to generic alternatives. The study found that F/TAF is not cost-effective and may even cause more avoidable HIV transmissions than it prevents.
Research by Yale School of Public Health reveals that over 30% of injury survivors experience moderate-to-severe PTSD symptoms within the first year. The study found factors such as physical assault, interpersonal violence, and lower educational attainment contribute to increased symptom severity.
A new study found that exposure to ultrafine particles in air pollution may trigger a nonfatal heart attack within hours. The research, published in Environmental Health Perspectives, analyzed data from over 5,900 patients in Germany and found stronger effects on health with particle length and surface area concentrations.
Researchers found a 15% increase in gonorrhea and a 10% increase in chlamydia rates in Texas counties with high shale drilling activity. This contrasts with no association observed in Colorado or North Dakota, suggesting the impact may be specific to densely populated areas.
