Hospital Wastewater as a Reservoir for Antibiotic Resistance Genes: A Meta-Analysis
2020
Background: The emergence and dissemination of antibiotic resistance genes (ARGs) in the environment poses a huge global health hazard. Hospital wastewater (HWW), in which a high density of antibiotic residues and antibiotic-resistant bacteria are present, may be a reservoir of ARGs dissemination into the environment. Our meta-analysis comprehensively analyzes the prevalence of ARGs in HWW, as well as the influencing factors in ARGs distribution. Methods: Online databases were used to search for literature using the subject terms: “Drug Resistance” AND “Genes” AND “Hospitals” AND “Wastewater.” Two reviewers independently applied predefined criteria to assess the literature and extract data …
Are the Adverse Drug Reactions of Amoxycillin and Amoxycillin-Clavulanic Acid Similar?
1996
UNLABELLED In an attempt to assess the relative toxicity of amoxycillin and amoxycillin-clavulanic acid, we compared the adverse drug reactions reports collected using the spontaneous reporting system of a Regional Drug Surveillance Centre of Spain for both drugs between November 1986 and December 1992. During the 7-year period 1986-92, the 247 reports of amoxycillin-clavulanic acid represent twice the number of reports of amoxycillin alone, and the number of reports related with sales received concerning the association were higher than those concerning amoxycillin alone. The adverse effects classified as severe were quantitatively and qualitatively similar for both drugs and gastrointesti…
Validity and reliability of the DiCI for the measurement of shoulder flexion and abduction strength in asymptomatic and symptomatic subjects
2021
Background A higher risk of shoulder injury in the athletic and non-athletic population is frequently associated with strength deficits. Therefore, shoulder strength assessment can be clinically useful to identify and to quantify the magnitude of strength deficit. Thus, the aim of this study was to evaluate the validity and reliability of a DiCI (a new hand-held dynamometer) for the measurement of shoulder flexion and abduction strength in asymptomatic and symptomatic subjects. Methods Forty-three recreational athletes (29 males and 14 females; age: 22.1 ± 0.47 years; body mass: 68.7 ± 13.1 kg; height = 173.3 ± 9.7 cm) and 40 symptomatic subjects (28 males and 12 females; age: 49.9 ± 8.1 y…
Variation in predator species abundance can cause variable selection pressure on warning signaling prey
2012
Predation pressure is expected to drive visual warning signals to evolve toward conspicuousness. However, coloration of defended species varies tremendously and can at certain instances be considered as more camouflaged rather than conspicuous. Recent theoretical studies suggest that the variation in signal conspicuousness can be caused by variation (within or between species) in predators' willingness to attack defended prey or by the broadness of the predators' signal generalization. If some of the predator species are capable of coping with the secondary defenses of their prey, selection can favor reduced prey signal conspicuousness via reduced detectability or recognition. In this study…
Analysis of a herpetofaunal community from an altered marshy area in Sicily; with special remarks on habitat use (niche breadth and overlap), relativ…
2005
A field survey was conducted in a highly degraded barren environment in Sicily in order to investigate herpetofaunal community composition and structure, habitat use (niche breadth and overlap) and relative abundance of a snake predator and two species of lizard prey. The site was chosen because it has a simple community structure and thus there is potentially less ecological complexity to cloud any patterns observed. We found an unexpectedly high overlap in habitat use between the two closely related lizards that might be explained either by a high competition for space or through predator-mediated co-existence i.e. the prevention of the competitive exclusion of one lizard over the other. …
A New, Ecologically Self-Significant Metric of Species-Abundance Unevenness, Reliably Highlighting the Intensity of Interspecific Competition
2021
A wide series of commonly used metrics of abundance-evenness (or -unevenness) have been proposed to characterize synthetically the distributions of species-abundances, accounting for the hierarchic-like organization of species within natural communities. Among them, most – if not all–have been relevantly criticized on their serious limitations regarding both their “descriptive” and their “interpretative” capacities. From the descriptive point of view, many authors have already repeatedly emphasized the formal non-independenceof conventional (un-)evenness metrics with respect to species-richness, leading, in particular, to unacceptable bias when comparing communities differing by their speci…
The effects of competitiveness on trade balance: The case of Southern Europe
2016
AbstractAccording to conventional wisdom, “peripheral” Southern European members of the euro area (Greece, Italy, Portugal and Spain) suffer from a problem of competitiveness. Since their membership of the euro area renders devaluation impossible, adjustment should come through decreasing wages and prices in these countries, which, by improving the trade balance, should lead to a recovery of previous levels of employment and growth. In this paper, the authors estimate trade balance equations for the Southern European countries, both for total trade and for the trade performed with the European Union, taking three alternative measures of the real exchange rate, based on consumption price ind…
Trade balances and exchange rates in the long run for European Union countries
2000
This paper has found evidence that real effective exchange rates have a positive impact on the trade balance in the long run for major European Union countries. This result sheds more light on the long-run statistical relationship between those two variables, at least in the context of the Community. The existence of that link is sustained by the effects that income variables have on the trade balance. The outcomes of this analysis in support of a long-run equilibrium relationship are consistent with the imperfect substitutes model, confirming the validity of this model for economic policy implementation purposes. Low, long-run elasticities of the trade balance with respect to the real effe…
Higher education in the fight against poverty from the capabilities approach: The case of Spain
2017
Abstract This article describes relative poverty in Spain in relation to the other States in the European Union, following the European indicator AROPE. The official data provided by the National Statistical Institute of Spain and by Eurostat, refer to the year 2014 (the last one for which definitive data are available is 2015). Given the relative poverty of Spanish population, the failure of conventional economic theories, which conceive social development as GDP growth, is clear, and it is argued in favour of the human capabilities approach as a more adequate option for development, from a theoretical-practical point of view, for the reduction and/or eradication of poverty, as well as the…
Cointegration and the PPP and the UIP hypotheses: An application to the Spanish integration in the EC
1996
The aim of this paper is to find some empirical evidence on Purchasing Power Parity (PPP) and Uncovered Interest Parity (UIP) in the Spanish case vis a vis the European Community for the period 1980–89. The main contribution of the paper is the aggregation of the variables corresponding to the countries that participate in the exchange rate mechanism of the European Monetary System. The results support the importance of the interest differential as an explanatory variable for the short-term adjustment to the PPP. The results follow from powerful estimation techniques, applied in the framework of a multivariate error-correction model using the maximum-likelihood procedure as developed by Joh…
