The Southwestern USA has been identified as one of the most persistent dust-producing regions of North America, where exposure to inhalable particulate matter (PM10) originating from desertic landscape during dust events/dust exposures (DEs) can reach hazardous levels. El Paso, Texas’s ambient air has reached hazardous levels of PM10 from dust with near zero visibility due to these natural events originating in the surrounding Chihuahuan Desert. The aim of this study was to investigate whether dust exposures in El Paso (generally acute, short-term exposures from nearby source areas) are associated with significant increases in hospitalizations on the day of the exposure and up to seven days afterwards. Using a Poisson regression, it was found that the relative risks of hospitalizations due to a variety of conditions were associated with dust exposures (through increases of 100 μg/m3 maximum hourly PM10 and/or increases of 4.5 m/s maximum hourly wind speed) in El Paso County, Texas between 2010 and 2014. Valley fever, coronary atherosclerosis, genitourinary diseases, neurodegenerative diseases, injury and poisoning, circulatory system conditions, respiratory system diseases, births, septicemia, Associated Diseases (the aggregation of hospital admissions for all causes, each associated with at least 5% of hospitalizations), and all ICD-9 admissions were significantly positively associated with dust exposures, indicated from higher to lower significant risk, at different lag periods after exposure. These findings, showing that an association does exist between dust exposures and hospitalizations, have important implications for residents of the world’s dryland cities.

Risk perception is used to quantify risks in the industry and is influenced by different socio-demographic variables. This work aims to determine significant differences in the risk perception between Mexican American migrants and first-generation Mexican American construction workers. This study used a sample of 112 construction workers. A guided questionnaire was applied to collect socio-demographic information. For workplace risk behaviors, we used a 21-item questionnaire adapted from the previous instrument. Each question asked the participant’s perception of the frequency with which they carried out risky activities during routine work activities and the severity of the possible injuries, using a five-level Likert scale. Then, an inferential analysis was carried out using analysis of variance (ANOVA). The main results highlight that time of residence in the United States had a significant influence (p = 0.012) on risk perception in the surveyed construction workers. On the other hand, the age and time they have been working for the organization did not significantly influence risk perception. Finally, risk perception can vary in construction workers according to different variables. It is essential to investigate the factors that influence it, to prevent risky behaviors that can lead to accidents.

This study examines the prevalence and severity of stress, anxiety, depression, and substance use among college students during the COVID-19 pandemic at a Hispanic-serving institution. The aim of the study is to increase knowledge about student mental health during a public health emergency in order to help develop strategies that promote student success. Using the Perceived Stress Scale-4 (PSS-4) and the Patient Health Questionnaire for Depression and Anxiety–4 (PHQ-4), we found high levels of stress, depression, and anxiety in the sample. Based on these findings, we propose a greater investment of time and resources to promote mental health and positive coping strategies among college students through culturally competent mental health and supportive programs.

The COVID-19 pandemic has had disruptive effects on college students globally. These include economic dislocation, social isolation, and financial stress. Minority and low-income students have experienced greater adversity than their peers. During the pandemic, college students have increased levels of stress, anxiety, and depression, particularly among minority groups. We conducted a cross-sectional study using standardized instruments (PSS-4 and PHQ-4) to determine the prevalence of stress, anxiety, and depression in a university attended by a majority of Latinx students. We also conducted a meta-analysis with the inverse variance method for pooling to compare the mean PSS-4 to other norm values. We found that Latinx students had a high prevalence of moderate to severe stress and high levels of anxiety and depression that varied by age and gender. This suggests that there is a need for outreach programs that address minority students’ mental health during the global public health crisis.
