A study led by Benoît Laplante finds that consensual unions have become increasingly popular among higher-income groups in Latin America. University-educated women are no longer limited to having children out of wedlock, as fertility rates correlate with living in a conjugal relationship rather than its legal nature.
A study by Population Council reveals that consensual unions are becoming a common family arrangement for bearing children among educated women in Latin America. The trend is seen as a shift from limited economic and social opportunities, with educated women now entering these unions to have children.

Despite facing numerous barriers, patients in the navigation program had shorter follow-up times and did not experience delayed diagnoses compared to English-speaking counterparts.
Researchers analyzed indicators of conflict and intergroup interaction in Eastern North America, finding that warfare varied widely over time and space. They identified patterns across extremely large areas, including fortified settlements and skeletal remains of warfare victims.
The rate of Latino physicians per 100,000 Latinos in the US has declined by 22% since 1980, according to a new study. The shortage of culturally familiar doctors negatively affects healthcare for U.S. Latinos, who face barriers to quality care due to language and cultural barriers.
The NELSON trial found that individuals with better health profiles and younger age were less likely to participate, but the study's findings remain relevant due to modest differences. The trial showed a higher mortality rate among eligible non-participants compared to participants.
A new study by St. Michael's Hospital found that 25% of homeless people surveyed in Toronto had vision problems, including blindness, four times higher than the general population. Glasses or contact lenses would help only two in five individuals with vision issues.

Researchers also found that these individuals were rearrested more frequently and sooner, highlighting the need for targeted immigration enforcement efforts.
Researchers identify a proactive approach to help low-SES smokers quit smoking, with telephone-based motivational counseling and free nicotine replacement therapy increasing quit rates. The study found that community resources, such as physical activity and job counseling referrals, were crucial in promoting tobacco cessation.
A randomized clinical trial found that a telephone-based motivational counseling intervention with tobacco treatment specialists increased quit rates among low-SES adult smokers compared to usual care. The program also showed promise in addressing social context factors related to smoking, with women, blacks, and those living in low-in...

A study found that 55% of the US population is not eligible to donate a kidney due to preventable health conditions such as hypertension, obesity, and diabetes. The majority of individuals with lower incomes are less likely to donate due to financial difficulties and immigration status.
A study found that patients with chronic hepatitis C virus infection and advanced fibrosis or cirrhosis who attain SVR have survival rates comparable to those of the general population. However, patients without SVR experience reduced overall survival.
The number of Alzheimer's patients is expected to more than double in 40 years, while annual per-person costs will nearly quintuple from $71,000 in 2010. Delaying onset can reduce the prevalence and costs of the disease.
