The evolution of COVID-19: A discontinuous approach.
2021
The evolution of the COVID-19 disease is monitored on the basis of the daily number of infected patients and the daily number of deaths provided from national health agencies. The variation of such parameters with time parallels that described for the growth/decay of historic transportation systems revealing the appearance of discontinuities. The evolution of the pandemic disease is represented in terms of two nominally equivalent formulations: a logistic model with sharp changes in its rate parameters, and in topological terms resulting in 2nd order phase transitions in the infected patients/time space.
Fumador, exfumador y COVID-19: la nicotina no protege contra el SARS-CoV-2
2021
Queremos agradecer a Moril et al.1 el interés en nuestro trabajo, pues nos permite reflexionar sobre el tema. La proteína Spike del SARS-CoV-2 es la responsable de facilitar su entrada a las células humanas, requiriendo cebado por la proteasa TMPRSS2 que permite la fusión de las membranas viral y celular2. El receptor utilizado por la proteína Spike es la enzima convertidora de angiotensina 2 (ACE2)2, que se expresa en diferentes estirpes celulares, además de en el pulmón; existiendo, a nivel pulmonar, un gradiente de expresión de ACE2 (mayor expresión en vías respiratorias superiores [epitelio nasal] y menor en los neumocitos alveolares)2. Se sugiere que una mayor expresión de ACE2 podría …
Surveillance of Municipal drinking-water supply after a Norovirus outbreak in Italy
2012
BACKGROUND Norovirus (NoV), in the family Caliciviridae, is the major causative agent of non-bacterial acute gastroenteritis, whose possible routes of transmission include drinking water. During March 2011 an outbreak of gastroenteritis was identified by the local public health service in S. Stefano di Quisquina, Sicily, Italy. Over two weeks, 156 cases were identified and NoV genotype GII.4 v2010 was detected in stool samples from eleven out of twelve patients. The finding of identical genomic sequences between patients suggested a common infection source and an epidemiological investigation indicated a possible correlation to municipal drinking water consumption. One of the wells supplyin…
Perceived Onset Time of Medical Conditions: The Interplay Between Subjective Fear and Risk in Four Lifestyle Domains
2022
Engaging in unhealthy behaviors (e.g., smoking, drinking) and not engaging in healthy ones (e.g., exercising, consuming fruit and vegetables) are both relatively prevalent among individuals despite the available information about their risks for health. People’s perception of an event’s time course can be used to gauge their risk perception for that event thus casting light on any possible misperception and suggesting directions for health-promoting interventions. This study investigates people’s perception of the time of onset of 5 noncommunicable diseases (e.g., “having high blood pressure”) associated with 4 health-related behaviors: Smoking, drinking, exercising, and eating fruit and v…
COVID-19 Infection in Cancer Patients: How Can Oncologists Deal With These Patients?
2020
The world is facing a new pandemic caused by a novel beta coronavirus (COVID 19), which causes severe respiratory coronavirus syndrome (SARS-CoV-2). Unfortunately, there are currently no US Food and Drug Administration (FDA) approved medications for the treatment of COVID-19 patients. High mortality rates in frail patients is a notable feature of the virus registered since the onset of COVID-19 pandemic. Above all, elderly patients or those with underlying chronic illnesses and compromised immune system are most at risk (1). Thus, the consideration is that the possible coexistence, in the same individual, of a cancer diagnosis and a COVID-19 infection could generate a synergistic negative p…

Regime Type and COVID-19 Response
2020
From late 2019 to the first half of 2020, the world has witnessed the epic spread and destruction of the novel coronavirus which was discovered in Wuhan, China. The huge number of infections and deaths caused by the virus, the collapse of the healthcare system and the economic consequences have few modern equivalents. While governments of all countries are responding to the pandemic, a heated debate rages about which political system, democracy versus authoritarian, is better positioned to respond to the pandemic. While the worldwide effort to contain the virus continues, we offer a preliminary comparison between democracies and authoritarian regimes in their responses to COVID-19, and pol…
Suddenly Working From Home!
2022
Abstract. The Corona crisis and the lockdown in the spring of 2020 had various effects on working life in Europe. In this three-wave study, we assessed the trajectories of job demands and resources of 302 employees 2 weeks before the lockdown, over 1 week after lockdown start, and 6 weeks following the beginning of the lockdown. We applied a pre-post follow-up design with 129 employees who switched to telecommuting and a control group of 173 employees who remained in their on-site workplace. Results from the repeated-measures MANCOVA indicate that, despite various general changes to job characteristics because of the Corona crisis, telecommuting changes contributed to significant changes on…
