Efficiency of COVID-19 Testing Centers in Iran: A Data Envelopment Analysis Approach

2022

AbstractObjective:The purpose of this study is to investigate the efficiency of the Iranian Red Crescent Society (IRCS) in managing their nonmonetary resources involved in coronavirus disease 2019 (COVID-19) response.Methods:For this purpose, the data envelopment analysis approach was used to measure the efficiency, considering the number of personnel and vehicles and screened passengers as the input and output parameters, respectively. It was examined the efficiency of 10 IRCS’s branches given 17 d of screening operation. For the analysis, the DEA SolverPro software 15a version was used.Results:The results show that only 1 branch had been fully efficient in using the resources, while 5 bra…

Antioxidant Effects of Dietary Supplements on Adult COVID-19 Patients: Why Do We Not Also Use Them in Children?

2022

Respiratory tract infections (RTIs) are very common in children, especially in the first five years of life, and several viruses, such as the influenza virus, Respiratory Syncytial Virus, and Rhinovirus, are triggers for symptoms that usually affect the upper airways. It has been known that during respiratory viral infections, a condition of oxidative stress (OS) occurs, and many studies have suggested the potential use of antioxidants as complementary components in prophylaxis and/or therapy of respiratory viral infections. Preliminary data have demonstrated that antioxidants may also interfere with the new coronavirus 2’s entry and replication in human cells, and that they have a role in …

Antifouling Mortars for Underwater Restoration

2022

This research has focused on the assessment of the compositional features and mechanical and antifouling performances of two different mortars formulated for an underwater setting, and which contain Mg(OH)2 as an antifouling agent. Regarding the mechanical characterization, the uniaxial compressive strength and flexural strength were measured. The composition of the materials was explored by differential thermal/thermogravimetric analysis (DTA-TG), X-ray diffraction analysis (XRPD), and scanning electronic microscopy (SEM) coupled with EDS microanalysis. The assessment of the biological colonization was evaluated with colorimetric analysis and image analysis. The results suggest that both m…

THE MOSAIC OF THE FRIGIDARIUM OF “VILLA BONANNO” IN PALERMO: MINERALOGICAL AND PETROGRAPHIC ANALYSES FOR IN SITU CONSERVATION AND RESTORATION INTERVE…

2018

The topic of this study was the mineralogical and petrographic characterization of bedding mortars (made of different layers) and tesserae of Roman age (3rd century A.D.), taken from the mosaic of the Frigidarium of “Villa Bonanno”, brought to light by archaeological excavations conducted in the historical centre of Palermo. The collected samples have been analysed by thin-section optical microscopy (PLM), and scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDS). The study was aimed to define the “recipe” (composition of aggregate and binder, aggregate size distribution, aggregate/binder ratio), in order to assess the provenance of raw m…

Prevalence of dry eye disease in elderly individuals of the French population (the MONTRACHET Study)

2013

Purpose To report the prevalence of dry eye in a large population-based sample of French individuals older than 75 years. Methods About 9000 individuals 65 years and older were included in the 3C cohort study since 1999 in 3 French cities (Bordeaux, Dijon and Montpellier). In Dijon, an additional ophthalmic examination was performed 10 years after the initial inclusions to assess the relation between systemic age-related diseases and eye diseases in the MONTRACHET Study (Maculopathy Optic Nerve nuTRition neurovAsCular and HEarT diseases). Dry eye symptoms were collected with self reported history of dry eye symptoms, use of topical medications and evaluated by the Ocular Surface Disease Ind…

ANALYSIS OF THE IMPACT OF EXOGENOUS FACTORS ON THE FINANCIAL PERFORMANCE OF ROMANIAN COMMERCIAL BANKS LISTED ON BUCHAREST STOCK EXCHANGE

2015

The interest of both creditors and debtors of a credit institution on the performance registered by commercial banks imposed shaping high prudential standards designed to not upset the credit institution and to contribute decisively to increase their health profitability. On bank performance it shows a significant influence on many factors. The study focuses its attention on the impact of research that external factors are likely to print to financial rate of credit institutions (one of the classic indicators used to measure bank performance). The variables studied were represented by: - external factors: GDP, inflation and exchange rate leu-euro - considered to be independent variables and…

Olive oil intake and risk of cardiovascular disease and mortality in the PREDIMED Study

2014

[Background] It is unknown whether individuals at high cardiovascular risk sustain a benefit in cardiovascular disease from increased olive oil consumption. The aim was to assess the association between total olive oil intake, its varieties (extra virgin and common olive oil) and the risk of cardiovascular disease and mortality in a Mediterranean population at high cardiovascular risk.

COVID-19: opinions and behavior of Italian general population during the first epidemic phase

2022

Background and aim: On January 9, 2020, the World Health Organization (WHO) declared that Chinese health authorities had identified a new coronavirus strain never before isolated in humans, the 2019-nCoV later redefined SARS-CoV-2, that still today represent a public health problem. The present survey started on 10 February 2020 with the aim of a) assessing the risk perception in healthcare workers and young students, following the evolution of attitudes, perception and knowledge over time, b) provide useful information to the general population during survey. Results: A study sample consisting of 4116 Italian in-dividuals of both sexes was enrolled. High levels of risk perception, low perc…
