ABSTRACT

Background: We aimed to: (1) analyze differences in both general (in terms of psychological well-being/discomfort, social functioning and coping, and psychological distress) and specific (depression, trait-anxiety, negative alcohol-related consequences, and suicidal risk) mental health state (MHS) in college students, residing in four different Argentinean regions (center, north, south, and the most populated) exposed to different spread-rates of the COVID-19; (2) analyze between-group differences in both general and specific MHS indicators at four quarantine sub-periods (twice prior, and twice following the first quarantine extension). Methods: We used a cross-sectional design with a convenience sample including 2,687 college students. Data was collected online during the Argentinean quarantine. We calculated one-way between-groups ANOVA with Tukey's post hoc test. Results: Regionally, the center and the most populated area differed in psychological well-being/discomfort and negative alcohol-related consequences, but not in the remaining MHS indicators. According to the quarantine sub-periods, there were differences in psychological well-being/discomfort, social functioning and coping, psychological distress, and negative alcohol-related consequences. Negative alcohol-related consequences were the only MHS indicator improving over time. For all of the remaining MHS indicators, we found a similar deterioration pattern in the course of time, with mean scores decreasing from the first to the 2nd week of the quarantine pre-extensions, then increasing toward the 1st week of the quarantine post-extension (with some MHS indicators reaching mean scores worse than the start), and then continued to increase. Conclusion: A worsened mean MHS during quarantine suggests that quarantine and its extensions contribute to negative mental health impacts.

ABSTRACT

The Lithium Triangle in the Andean plateau involves high altitude (>3,000 m asl) hydrological systems having high lithium graded waters. This research was carried-out in rural areas of north westernmost Argentinean Andes and was aimed: 1) to determine concentrations of lithium in drinking waters; 2) to calculate suicide mortality rates based on available official data (2003-2013); 3) to analyze bivariate differences between lithium concentrations in drinking water, mean rates of suicide mortality, altitude of sampling sites, and water sources; 4) to analyze bivariate correlations between lithium concentrations in drinking water, mean rates of suicide mortality, and altitude; 5) to test predictive models for mean rates of suicide mortality, when considering the predictors lithium concentrations in drinking water, altitude, and water sources. Lithium determinations in drinking waters were performed by Microwave Plasma-Atomic Emission Spectrometer. Nonparametric tests were applied to analyze differences and correlations. Generalized linear models (GLM) were used to fitting models for mean rates of suicide. Drinking waters contained up to 2.98 mg L-1 of lithium. Mean rates of suicide mortality (per 100,000 inhabitants) were high, ranging from 19.12 (± 19.83) to 30.22 (± 16.70). Lithium but not altitude was positively correlated with suicide mortality when analyzing bivariate correlations (Li: rho = 0.76, p-value < 0.001). However, when GLM were calculated, a significant interaction effect was found between lithium and altitude (p-value < 0.001). This interaction effect would act in some way restraining the suicide mortality rates.

ABSTRACT

The Quebrada de Humahuaca in North West Argentina is a world heritage site listed by the UNESCO since 2003. As pollution is increasing dramatically, a pluridisciplinary, annual-long survey was conducted along the valley to determine dominant patterns in waste management and water quality. Along with the habit of discarding waste into the river, urbanizations have been identified as having a deep influence on the river water quality: iron together with maximum peaks of nitrite and nitrate are related with the anthropogenic activity at Humahuaca, whereas the concentrations of arsenic increase from north to south, with maximum peaks of up to 13.50 and 14.50 µg L-1 measured during the rainy season at Maimará and Volcán, respectively. In this underdeveloped region, economic struggles and waste management customs revealed as major factors causing the environmental degradation. The inclusion in the UNESCO's sites list was insufficient in preserving this world heritage site. The approach discussed in this article suggests a straightforward analytical measurement of the river hydrochemical properties during the rainy season in arid/semi-arid regions with monsoonal regime, to assess the effects of waste dumping along watercourses. In addition to scientific evaluations, both public acceptance and the establishment of proper waste management infrastructure are fundamental to ensuring the preservation of human and environmental health.

ABSTRACT

BACKGROUND: Mental health practices consider unemployment as a suicide main risk factor, based on models built for populations of developed countries. AIM: This study assesses the association between the occupational risk factor and suicidal behaviors, by considering sex, age and temporal distribution, in a Latin American Andean population from north westernmost Argentina. METHODS: Data include 481 suicide attempt cases assisted by emergency service psychologists at a head hospital in the Jujuy Province, northern Argentina, during two biennials. General categories and specific types of occupational situation, sex, age and temporal distribution were analyzed. RESULTS: 83.58% of cases corresponded to the with occupation category, but without occupation characterized male cases (p-value = .01). The type no referred occupation (19.15%) mainly contributed to this association (p-value = .02). Unemployed only represented 1.6%. These features revealed independent from the biennial period of assistance (p-value = .96 (general), p-value = .86 (specific)). Associations by age ranges did not seem to be specific of suicidal attempts. CONCLUSION: The present contribution provides an occupational characterization of suicide attempts in an Andean population from north westernmost Argentina. Unemployment is not associated with suicidal behavior in this population, suggesting that dissimilar patterns underlie suicidal behavior of populations from developed and developing regions.

ABSTRACT

Vicuna is a wild, endangered species of Andean camelid living in the hyperarid Andean plateau. In the central part of the plateau, the Lithium Triangle defines a zone with lithium-rich salt pans. Brine pools naturally form within the salt pans, and the adaptation strategy of vicuna consists of drinking from brine pools. Together with reporting the first chemical data on vicuna bones and teeth, we analyzed lithium, boron, and arsenic in water and brines, with the aim of assessing their relation to chronic exposure by water ingestion. We collected and analyzed bones of vicuna specimens lying in an Andean salt pan, together with brine and water samples. Brine and water samples are highly saline and contain large amounts of lithium, boron, and arsenic. Lithium (13.50-40 mg kg-1 ) and boron (40-46.80 mg kg-1 ), but not arsenic, were found in the vicuna bones and teeth. Based on our results and on previously reported data on human tissues in the Andes, we conducted statistical assessments of the relationships between lithium and boron in body tissues and water samples, and discuss their environmental significance in the context of the Lithium Triangle.
