Validating Habitual and Goal-Directed Decision-Making Performance Online in Healthy Older Adults
2021
Everyday decision-making is supported by a dual-system of control comprised of parallel goal-directed and habitual systems. Over the past decade, the two-stage Markov decision task has become popularized for its ability to dissociate between goal-directed and habitual decision-making. While a handful of studies have implemented decision-making tasks online, only one study has validated the task by comparing in-person and web-based performance on the two-stage task in children and young adults. To date, no study has validated the dissociation of goal-directed and habitual behaviors in older adults online. Here, we implemented and validated a web-based version of the two-stage Markov task usi…
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 …
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…

Effects of low laser level therapy in rehabilitation of patients with COVID19 pneumonia
2021
Introduction. An unprecedented public health crisis has been triggered worldwide by SARS-CoV-2’s high contagiosity and it’s mortality rates of 1-5%. Although the majority of COVID-19 cases have a good outcome, there is a small percentage that develop severe pneumonia and citokine storm and may be in the need of mechanical ventilation. Methods. Identifying the exact drivers of the excessive inflammation and the biomarkers that can predict a hyperinflammatory response to SARS-CoV-2 would be extremly helpful in finding efficient anti-inflammatory interventions that may stop the progression to acute respiratory distress syndrome (ARDS). Results. In the search for such interventions we have iden…
Desarrollo de Aptazovid: aptasensor piezoeléctrico para la detección de SARS-CoV-2
2021
SARS-CoV-2 ha dado lugar a una pandemia en la que la detección y aislamiento de personas infectadas es clave para luchar contra el virus. La detección puede ser directa o indirecta con diferentes dianas y muestras de partida, aplicando técnicas tan conocidas como la RT-PCR o desarrollando nuevos métodos que integran herramientas como CRISPR, aunque con ciertas limitaciones. Desde hace algún tiempo, los biosensores están en auge y la pandemia ha favorecido la inversión en el desarrollo de tecnologías que superen los inconvenientes de metodologías más tradicionales. En este contexto, como solución surge Aptazovid, un aptasensor piezoeléctrico que detecta directamente la glicoproteína de super…
SARS-COV-2 PANDEMIC IN THE MEDITERRANEAN AREA: EPIDEMIOLOGY AND PERSPECTIVES
2020
In December 2019, a disease caused by a novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was identified in Wuhan, Hubei Province, China. In March 2020, the World Health Organization declared the pandemic due to SARS-CoV-2. At the end of May 2020, SARS-CoV-2 confirmed cases and deaths due to novel Coronavirus disease (COVID-19) were about 6.5 million and 380,000, worldwide. In this commentary the authors argue on the impact of SARS-CoV-2 pandemic in different epidemiological settings within the Mediterranean area, discussing any possible association with higher or lower virus spread according to climatic factors, pollutants, characteristics of general population, and organi…
THINKING ABOUT OPHTHALMOLOGY IN THE ERA OF THE COVID-19 PANDEMIC
2020
There is no part of the health care system that has remained unscathed by the COVID-19 pandemic in terms of its organizational, scientific or medical models. The surgical specialities were called upon to analyse the concepts of urgency and deferrable, reconsider the procedures and the times for those, and to evaluate new and specific strategies for the remote and safe management of patients. The aim of this paper is to evaluate new and different approaches in the field of ophthalmology triggered by the COVID-19 emergency. We analysed literature and on line documents; key words for the research were: SARS-CoV-2, COVID-19, ophthalmology, ophthalmologist, eye, guidelines, and their combination…
