Interannual variation in filling season affects zooplankton diversity in Mediterranean temporary ponds

In Mediterranean temporary ponds, the timing of annual flooding is highly variable and depends on heavy seasonal rains. Ponds can flood in the autumn, winter, or spring, and thus the environmental conditions faced by emerging zooplankton can be very different. We performed an experiment in a climatic chamber where we simulated annual variation in natural temperature and light conditions to study how differences in pond-filling season affected zooplankton assemblage composition. We sampled sediments from a temporary pond and placed them in aquariums that were filled with water during three different seasons: autumn (October), winter (January), and spring (March). Zooplankton abundance, species richness, diversity, and assemblage composition differed significantly among treatments, and post-inundation temperature and pH appeared to be the main drivers of these differences. Diversity was highest in the winter treatment. It was lower in the autumn treatment and the spring treatment, and no indicator species were present in the latter. Our results suggest that interannual variability in initial inundation conditions favours the emergence of different species and thus contributes to high species richness in the egg bank. However, climate change and/or groundwater drawdown could delay pond flooding, impoverishing the zooplankton assemblage in the long ter

Association between Crystalline Silica Dust Exposure and Silicosis Development in Artificial Stone Workers

Occupational exposure to respirable crystalline silica (SiO2 ) is one of the most common and serious risks because of the health consequences for the workers involved. Silicosis is a progressive, irreversible, and incurable fibrotic lung disease caused by the inhalation of respirable crystalline silica dust. A cross-sectional epidemiological study was carried out to assess the occupational risk factors that may contribute to the onset of silicosis in workers carrying out work activities with the inhalation of silica compact dust. The study population consisted of 311 artificial stone workers from the province of Almeria (southeast of Spain). Among them, 64 were previously diagnosed with silicosis and the rest of the participants (n = 247 workers) were not diagnosed with such a disease. The workers showing a greater risk of developing silicosis were those who installed kitchen worktops at consumers’ homes, as they did not use face-masks or were not provided with personal protective equipment (PPE) by their business. The results of this study provide support for the evidence indicating that silicosis is a major emerging health concern for workers in the artificial stone sector. Exposure to crystalline silica dust thus can influence the development of silicosis in those cases where individual and collective protection measures are not used or adequately applied

Nivel de riesgo para diabetes tipo 2 en personas que acuden a consulta externa de un hospital público de Morelia, Michoacán, México

Objective: To evaluate the level of risk for type 2 diabetes in persons attending outpatients at a public hospital in Morelia, Michoacán, Mexico. Method: Quantitative study with descriptive and cross-sectional design; a probability sample of 327 persons selected by simple random sampling, users of a public hospital. FINDRISC instrument that measures risk for type 2 diabetes. Descriptive statistics were used for the analysis in the SPSS v.25 program. The right of withdrawal and confidentiality were respected. Main results: 100% of the participants were women; the majority were adults (75.5%), married (25.7%), housewives (59.9%), living in Michoacán (89%) and residents of Morelia (73.4%). It was also found that 36.4% of the subjects were overweight, 59.6% with abnormal blood pressure and 56% with normal glucose. Very high risk of developing diabetes was found in 24.5% and high risk in 20.5%. There was a statistically significant relationship between risk for diabetes with age, schooling, marital status, and occupation (p>.05). General conclusion: Four out of 10 participants presented a very high and high level of risk of developing diabetes in the next 10 years, so nursing should develop a care plan according to the needs of the person at risk of developing the disease that allows establishing an axis of prevention or improvement.Objetivo: Evaluar el nivel de riesgo para diabetes tipo 2 en personas que acuden a consulta externa de un hospital público de Morelia, Michoacán, México.

Conclusión general: Cuatro de cada 10 participantes presentaron un nivel muy alto y alto de riesgo para desarrollar diabetes en los próximos 10 años, por lo que enfermería debe elaborar un plan de cuidados según las necesidades de la persona con nivel de riesgo para desarrollar la enfermedad que permita establecer un eje de prevención o mejora

Biomonitoring of common organophosphate metabolites in hair and urine of children from an agricultural community

Levels of dialkylphosphate (DAP) metabolites were measured in hair and urine of children that lived close to intensively farmed areas of Almeria (Southeast Spain). The levels were used as proxies for exposure of these children to organophosphate pesticides (OPs). Determinants of exposure to DAPs were also examined. Urine and hair samples were collected from 222 children aged 3–11 years and information on lifestyle and dietary habits was collected from questionnaires administered to mothers. Urinary DAPs were analyzed by ultra-high performance liquid-chromatography coupled to triple-quadrupole tandem mass-spectrometry (UHPLC-QqQ-MS/MS) and hair DAPs by gas-chromatography coupled to mass spectrometry (GC–MS). Detection rates ranged from 21.8% for diethylphosphate (DEP) and diethylthiophosphate (DETP) to 35.9% for dimethylphosphate (DMP) in urine; and from 42.3% for DETP to 92.8% for DMP in hair. Diethyldithiophosphate (DEDTP) was detected in 0.5% of urine samples (one child), and in 26.6% of children's hair samples. A lack of correlation was observed for individual DAP metabolites and ΣDAPs between urine and hair samples, except for DEDTP. Urinary DAP levels of our child population were lower than those reported for children from other countries, including NHANES 1999–2000 data.This study was partially funded by the Ministry of Economy, Innovation, Science and Employment, Government of Andalucia (reference number P08-CTS-04313, FEDER funds)

Evaluation of Gonadal Alterations in a Population Environmentally Exposed to a Mixture of Endocrine Active Pesticides

Although there are studies that show that some pesticides produce gonadal dysfunction and gonadal cancer in different animals, there are not many studiesregardinghumans. This study determined the prevalence and risk in humans of developing ovarian or testicular dysfunction or cancer in areas with distinct exposure to pesticides, which have endocrine disrupting properties. A population-based case-control study was carried out on humans living in ten health districts of Andalusia (Southern Spain) classified as areas of high or low environmental exposure to pesticides according to agronomic criteria. The study population included 5332 cases and 13,606 controls. Data were collected from computerized hospital records between 2000 and 2018.The risk of gonadal dysfunction or cancer was significantly higher in areas with higher use of pesticides in relation to those with lower use
