Wastewater Surveillance of SARS-CoV-2: A Comparison of Two Concentration Methods.

Wastewater surveillance is crucial for the epidemiological monitoring of SARS-CoV-2. Various concentration techniques, such as skimmed milk flocculation (SMF) and polyethylene glycol (PEG) precipitation, are employed to isolate the virus effectively. This study aims to compare these two methods and determine the one with the superior recovery rates.

Impact of meteorological factors on the emergence of bronchiolitis in North-western Greece.

Objective: To evaluate the relationship between meteorological factors in North-western Greece and the incidence of bronchiolitis.

Methods: Meteorological data (air temperature and rainfall) for Ioannina city in North-western Greece and medical data from hospitalised patients at University Hospital of Ioannina were collected between January 2002 and December 2013. The association between meteorological factors and rate of hospitalisation due to bronchiolitis was investigated.

An Aggregate of Four Anthrax Cases during the Dry Summer of 2011 in Epirus, Greece.

Background: Human anthrax is currently a sporadic disease in Europe, without significant regional clustering.

Objective: To report an unexpected aggregate of anthrax cases and correlate local climatic factors with yearly anthrax admissions.

Methods: Clinical description of a geographical-temporal anthrax aggregate, correlation of disease admissions with local weather data in the period 2001-2014 and literature reports of anthrax clusters from Europe in the last 20 years.

Low back pain under control - Bartzokas' maneuver: a case report.

Low back pain (lumbago) is a common health problem globally. It is related to age, modern lifestyle (no exercise etc), and injuries. Its treatment includes a very broad spectrum of methods and its prevention is still unclear.

A comparative study on various statistical techniques predicting ozone concentrations: implications to environmental management.

The objective of the present work is to compare various techniques for modeling the dependence of the tropospheric ozone concentrations on several meteorological and pollutant parameters. The study focuses on two different sites in the metropolitan area of Athens, Greece; one in the city centre and another one in the suburbs. It is found that although simple Linear Regression Analysis fails to construct accurate equations due to the existence of multicollinearity among the independent variables, still various combinations of a Multivariate Method (PCA) and Stepwise Regression Analysis manage to produce equations free of the multicollinearity issue.
