A new Dartmouth-led study found a direct association between the infant microbiome and early childhood behavioral health, with sex-specific differences. The study characterized the species of microbes present in each participant's gut and their functions, establishing that microbiome changes occur before behavioral changes.
New research highlights the importance of social support during pregnancy, finding that women with low levels of emotional or affectionate support are at increased risk of depression and anxiety. The study suggests that screening for social support and providing community-based services may help improve health outcomes.
A five-year study aims to identify hormone responses in a population of Mexican Americans with prediabetes, Type 2 diabetes, and obesity. The research uses genetic data and physiologic testing to guide optimal treatments for diabetes, prediabetes, and related diseases.
The study analyzed data from 8,502 genetically high-risk children and found that half developed type 1 diabetes before age 6, while the other half developed it between ages 6 and 12. The findings suggest a different form of type 1 diabetes emerges in children as they grow older.
A large Swedish cohort study found that obese patients (BMI >35 kg/m2) were twice as likely to experience a prolonged ICU stay or die from COVID-19. The study also showed that obesity is an independent risk factor for severe outcomes, suggesting closer monitoring for individuals with obesity hospitalized for COVID-19.
A Brazilian study found that children exposed to malaria from birth are more likely to develop anemia by age two. The researchers, led by Dr. Marly Augusto Cardoso, followed 1,539 children and discovered that 12.6% were anemic, with a higher prevalence in rural areas not covered by the study.

The results highlight the importance of timely treatment and rehabilitation to prevent social exclusion.
A retrospective cohort study of 27 patients with sarcoma lung metastases found high primary technical success rates for percutaneous image-guided microwave and cryoablation. The treatment modality and tumor location did not affect local progression, and smaller tumors showed lower cumulative incidence of local progression.
A new study co-led by UCL researchers found that people with higher pre-pandemic levels of depression or anxiety were more severely affected by job and healthcare disruptions during the pandemic. Those with severe symptoms experienced a much greater likelihood of disruptions to jobs, income, and healthcare.
The number of autism diagnoses in England has skyrocketed by 787% over the past two decades, driven primarily by increased recognition and improved diagnosis for females. Researchers analyzed GP records and found that the greatest rises were among adults, with females making up most of the increase.

The study suggests that structural racism has persisted with similar magnitude across generations, leading to increased death rates among Black individuals compared to their White counterparts.
A new study suggests that girls are less likely to view science as a viable career when taught alongside confident and aspirational peers. Contrary to expectations, boys' confidence in STEM subjects is more likely to inspire them to pursue careers in the field.
A study found that higher omega-3 acid levels in the blood are associated with a significant increase in life expectancy, similar to quitting smoking. The researchers analyzed data from over 2,200 people aged 65 and found that four types of fatty acids, including omega-3, can predict mortality risk.
A new saliva collection method involves self-collection by licensed dentists followed by mailing to a laboratory, demonstrating feasibility for large-scale analysis. This approach offers a cost-effective alternative for COVID-19 diagnostics, preserving saliva samples for up to 7-10 days at room temperature with stabilizers.

Researchers at La Jolla Institute for Immunology found that people who recovered from COVID-19 or received Moderna or Pfizer-BioNTech vaccines have cross-reactive T cells that can target several SARS-CoV-2 variants. This reactivity is key to the body's immune response, allowing it to kill infected cells and stop severe infections.
A study published in Environmental Pollution found that organic food intake is associated with better scores on tests of fluid intelligence and working memory. Poor nutrition, house crowding, and indoor air pollution were also linked to poorer cognitive function.
A curriculum with additional math instruction led to higher attendance and degree completion rates for students in a 2003 cohort. However, similar effects were not seen in a 2004 cohort, suggesting that pairing high- and low-skilled students undermines positive impacts of extra math support.
A study evaluated a panel of 142 mutation-signature–associated metrics for predicting cancer progression in patients. The P142 panel successfully predicted cancer progression status in some, but not all, analyzed cancer types.

New research published in the Canadian Medical Association Journal shows that planned cesarean deliveries on maternal request are safe for low-risk pregnancies. The study analyzed data from over 422,000 pregnancies and found that mothers who requested cesarean delivery were more likely to have certain characteristics. Planned cesarean ...
A new study reveals that up to 24 percent of esophagectomy patients can develop Venous Thromboembolism (VTE), leading to significant morbidity and mortality. The six-month mortality rate for patients with VTE was found to be 17.6 percent, compared to 2.1 percent for those without.
Dr. Blaser recognized for groundbreaking research on the human microbiome and its relationship to diseases such as asthma, obesity, and cancer. His work has had a far-reaching impact on medicine and patient care, particularly in the areas of infectious disease and COVID-19.
A new study has found that the composition of a baby's first poop is associated with whether or not they will develop allergies within their first year of life. Newborns with richer meconium have a lower risk of developing allergies, suggesting that early exposure to certain molecules in the womb may play a role in future health.
A new study by Oregon State University has found that combining solar panels and lamb grazing increases land productivity. The research compared lamb growth and pasture production in pastures with solar panels to traditional open pastures, finding less overall but higher quality forage in the solar pastures.
Despite having clinically recovered from COVID-19, NBA players, staff, and vendors experienced persistent viral loads, indicating a high transmission risk. The study found that these individuals were more likely to transmit the virus to others, highlighting the need for continued precautions.
A new study reveals that proximity to existing solar panels is the most significant factor influencing an individual's likelihood of installing solar panels on their own roof. The findings suggest that seeding solar panels in areas with few or no panels can create a tipping point, potentially leading to widespread adoption and replacin...
A large study found that increasing physical activity levels is associated with a reduced likelihood of heart events and mortality in people with high blood pressure, high cholesterol, and diabetes. Participants who showed moderate to large improvements in physical activity were 30% less likely to develop cardiovascular disease or die ...
A large cohort study by Aarhus University found a clear association between silica exposure and increased risk of autoimmune rheumatic diseases, including rheumatoid arthritis and systemic sclerosis. Exposure to low levels of silica dust also posed a significant health risk.

Researchers investigated whether people affected by the 2017 Stockholm terrorist attack would change their political views on terrorism-related questions. Contrary to previous theories, they found no significant difference in attitudes among those who were close to the attack compared to those who were not. The study's findings suggest...
Endogenous Cushing's syndrome is associated with a threefold increase in death, primarily due to cardiovascular disease and infections. The study analyzed data from over 19,000 patients and found that mortality rates were lower after 2000, but still unacceptably high.
