Particle Exposure Hazards of Visiting Outdoor Smoking Areas for Patients with Asthma or COPD Even in EU Countries with Comprehensive Smokefree Laws.

Smokefree laws are intended to protect against second-hand smoke (SHS) in outdoor areas. We examined if exposure to PM2.5 particles in outdoor smoking areas changed breathing rates in 60 patients with asthma ( = 30) or with COPD ( = 30), in an open, non-randomised, interventional study model in Czechia, Ireland and Spain.

Measurement of airborne nicotine, as a marker of secondhand smoke exposure, in homes with residents who smoke in 9 European countries.

Objective: Smoke-free policies are effective in preventing secondhand smoke (SHS) exposure, but their adoption at home remains largely voluntary. This study aimed to quantify SHS exposure in homes with residents who smoke in Europe according to households' characteristics, tobacco consumption habits, and national contextual factors.

Methods: Cross-sectional study (March 2017-September 2018) based on measurements of air nicotine inside 162 homes with residents who smoke from nine European countries.

An alternative method for measuring total respiratory resistance during quiet breathing: a feasibility and validation study.

Objective: Determining the respiratory system's mechanical properties with minimal patient effort has been an important field of investigation addressing patients unable to perform pulmonary function testing and in light of the preventive measures due to the recent pandemic. The current study aimed to present an alternative method for total respiratory resistance measurement during tidal breathing, compare it with airway resistance (Raw), measured by body plethysmography, and validate the procedure in three groups of subjects with normal, constrictive and obstructive respiratory patterns in spirometry.

Patients And Methods: We developed an alternative method of assessing total respiratory resistance during quiet breathing.

Adherence to facemask use in public places during the autumn-winter 2020 COVID-19 lockdown in Greece: observational data.

Background: Wearing facemasks is of proven efficacy as a public health protective measure against COVID-19. Currently there are no observational data concerning the wearing of facemasks and the adherence to guidelines concerning their handling.

Methods: Registration of the way passers-by were wearing facemasks at 26 different locations of five major cities in Greece.

Perceived Importance of Public Health Risks in Greece: A Nationwide Survey of the Adult Population.

The current study is the first to examine the perceptions of the Greek public towards selected health risks and prioritize perceived risk importance and the needs to be addressed for public health promotion. Participants were asked to consider the individual importance of selected risks and the top three most important risks. Data collection took place on February 2020 in a representative sample of the adult Greek population.
