Air pollutants and daily number of admissions to psychiatric emergency services: evidence for detrimental mental health effects of ozone

Abstract Aims Aim of the current study is to investigate the associations between daily levels of air pollutants (particulate matter, ozone, carbon monoxide, nitrogen dioxide) and daily admissions for mental disorders to the emergency department of two general hospitals in Umbria region (Italy). Methods We collected data about daily admissions to psychiatric emergency services of two general hospitals, air pollutants' levels and meteorological data for the time period 1 January 2015 until 31 December 2016. We assessed the impact of an increase in air pollutants on the number of daily admissions using a time-series econometric framework. Results A total of 1860 emergency department admissions for mental disorders were identified. We observed a statistically significant impact of ozone levels on daily admissions. The estimated coefficient of O3 is statistically significant at the 1% level. All other pollutants were not significantly associated with the number of daily admissions. Conclusions Short-term exposure to ozone may be associated with increased psychiatric emergency services admissions. Findings add to previous literature on existing evidence for air pollution to have an impact on mental health. Ozone may be considered a potential environmental risk factor for impaired mental health

Inflammatory indexes as predictive factors for platinum sensitivity and as prognostic factors in recurrent epithelial ovarian cancer patients: a MITO24 retrospective study

Neutrophil-to-lymphocyte ratio (NLR) and systemic inflammatory index (SII) are prognostic factors in epithelial ovarian cancer (EOC). Their predictive value for platinum-sensitivity and their role in recurrent EOC are unknown. A total of 375 EOC patients were retrospectively analyzed. The correlation between baseline NLR and SII, and platinum-free interval (PFI) according to first line bevacizumab treatment were analyzed using logistic regression analyses adjusted for baseline patient characteristics. Subsequently NLR and SII calculated before second line treatment initiation were evaluated to identify a potential correlation with progression-free survival (PFS) and overall survival (OS) in platinum-sensitive and in platinum-resistant population. In multivariate analysis, NLR ≥ 3 is an independent predictive factor for PFI at 6 months in the chemotherapy group (OR = 2.77, 95% CI 1.38–5.56, p = 0.004), not in bevacizumab treated patients. After having adjusted for ECOG performance status, histology, ascites, bevacizumab treatment at second line and BRCA status, NLR ≥ 3 and SII ≥ 730 are significantly associated with worse OS in platinum-sensitive (HR = 2.69, 95% CI 1.60–4.53, p = 0.002; HR = 2.11, 95% CI 1.29–3.43, p = 0.003, respectively), not in platinum-resistant EOC patients. Low NLR is an independent predictive factor for platinum-sensitivity in patients treated without bevacizumab. NLR and SII are prognostic factors in recurrent platinum-sensitive EOC patients

Anuran responses to spatial patterns of agricultural landscapes in Argentina

Context: Amphibians are declining worldwide and land use change to agriculture is recognized as a leading cause. Argentina is undergoing an agriculturalization process with rapid changes in landscape structure. Objectives: We evaluated anuran response to landscape composition and configuration in two landscapes of east-central Argentina with different degrees of agriculturalization. We identified sensitive species and evaluated landscape influence on communities and individual species at two spatial scales. Methods: We compared anuran richness, frequency of occurrence, and activity between landscapes using call surveys data from 120 sampling points from 2007 to 2009. We evaluated anuran responses to landscape structure variables estimated within 250 and 500-m radius buffers using canonical correspondence analysis and multimodel inference from a set of candidate models. Results: Anuran richness was lower in the landscape with greater level of agriculturalization with reduced amount of forest cover and stream length. This pattern was driven by the lower occurrence and calling activity of seven out of the sixteen recorded species. Four species responded positively to the amount of forest cover and stream habitat. Three species responded positively to forest cohesion and negatively to rural housing. Two responded negatively to crop area and diversity of cover classes. Conclusions: Anurans within agricultural landscapes of east-central Argentina are responding to landscape structure. Responses varied depending on species and study scale. Life-history traits contribute to responses differences. Our study offers a better understanding of landscape effects on anurans and can be used for land management in other areas experiencing a similar agriculturalization process.Facultad de Ciencias ExactasCentro de Investigaciones del Medioambient

Assessing biochar impact on earthworms: Implications for soil quality promotion

Potential harmful effects of spent coffee grounds (SCGs)-derived biochar on earthworms (Lumbricus terrestris) were investigated through two complementary experiments, which assessed the avoidance response of earthworms to biochar-amended soils (experiment 1), and the response of oxidative stress biomarkers and digestive enzymes (experiment 2). The main results were: 1) the highest dose of biochar (5% w/w) caused a significant avoidance response of earthworms (75% individuals avoided these treated soils after 48 h); 2) signs of oxidative stress were early detected in earthworms exposed to biochar (1 and 5% w/w) as indicated by the integrated biological response index; 3) earthworms exposed to biochar-amended soils for 30 d experienced a significant increase of digestive enzyme activities measured in both the gastrointestinal tissue and the luminal content; 4) interaction between earthworms and biochar led to a higher soil extracellular enzyme activities in the 1% biochar treatment than that of control and 5% biochar treatments. These findings suggest that the joint application of SCG-biochar and L. terrestris is a workable approach for improving soil quality in terms of soil biochemical promotion, although earthworms may develop some physiological mechanisms of biochar tolerance (antioxidant defenses)

Il ruolo primario dell'indennizzo (L. 210/92) per un'adeguata campagna vaccinale in tempo di COVID-19

Dall'introduzione della legge 210/92 con la previsione di un indennizzo per lesioni o menomazioni permanenti a seguito di una vaccinazione obbligatoria per legge, la Corte Costituzionale ha ampliato, con specifiche analisi caso per caso e decisioni, anche a eventi avversi derivanti da vaccinazioni soltanto raccomandate, come il vaccino anti-COVID 19. L'Autrice auspica il riconoscimento diretto dell'indennizzo da parte del giudice ordinario competente anche in assenza di pronuncia della Corte Costituzionale, vista l'innegabilità della funzione pubblica e socialmente utile di ogni vaccinazione raccomandata, che velocizzerebbe i tempi di ristoro e conforterebbe la popolazione restia a sottoporsi al vaccino in tempi di pandemia
