Discrete magma injections drive the 2021 La Palma eruption.

Understanding the drivers of the onset, evolution, and end of eruptions and their impact on eruption style is critical in eruption forecasting and emergency management. The composition of erupted liquids is a key piece of the volcano puzzle, but untangling subtle melt variations remains an analytical challenge. Here, we apply rapid, high-resolution matrix geochemical analysis on samples of known eruption date spanning the entire 2021 La Palma eruption.

Hispanic Health Paradox at the Border: Substance, Alcohol, and Tobacco Use among Latinx Immigrants Seeking Free or Reduced-Cost Care in Southernmost Texas.

Objective: Although substantial research has explored the Hispanic health paradox (HHP) and suggests that Latinx immigrants experience positive health outcomes relative to those born in the United States, less research has assessed the role of immigration status. Our aim was to examine this role in Latinx health.

Methods: Using survey data collected at two free/reduced-cost clinics in southernmost Texas, we examined differences in the mental and self-rated health, substance, alcohol, and tobacco use of low-income patients by undocumented/documented immigrant and US-born/naturalized citizen status (N = 588).

Getting by with a Little Help from Our Friends: The Role of Social Support in Addressing HIV-related Mental Health Disparities among Sexual Minorities in the Lower Rio Grande Valley.

This study examines how social support and perceived discrimination influence depressive symptoms of sexual minorities (including, lesbian, gay, bisexual-identifying individuals, and others with same-sex sexual partners) relative to heterosexual peers, while considering the role of HIV-positive status. We surveyed low-income, predominantly Hispanic/Latino/as residents receiving STI-testing and/or HIV/AIDS care in the lower Rio Grande Valley of southernmost Texas. Respondents aged 18+ took a self-administered survey in English or Spanish in a clinic waiting room (= 273).

Social Determinants of Sexual Behavior and Awareness of Sexually Transmitted Infections (STI) Among Low-Income HIV+ or STI At-Risk Hispanic Residents Receiving Care at the U.S.-Mexico Border.

U.S.-Mexico border communities are uniquely vulnerable to sexually transmitted infection (STI) transmission given the economic and social challenges these communities face.
