Exposure to ambient air pollutants and short-term risk for exacerbations of allergic rhinitis: A time-stratified, case-crossover study in the three largest urban agglomerations in Poland.

Allergic rhinitis (AR) affects 10 % of the world population, with an increased prevalence in regions with substantial air pollution, but the association between exposure to air pollutants and the short-term risk of AR exacerbations is unclear. We used a time-series approach to analyze the risk of hospital admissions due to AR over 8 days from exposure to various air pollutants. Distributed lag nonlinear models were used to analyze data gathered between 2012 and 2018 in the three largest urban agglomerations in Poland.

Air pollution and long-term risk of hospital admission due to chronic obstructive pulmonary disease exacerbations in Poland: a time-stratified, case-crossover study.

Introduction: Airborne pollutants may worsen the course of chronic obstructive pulmonary disease (COPD). Previous studies have shown that both particulate and gaseous pollutants increase airway inflammation, which may lead to an exacerbation of COPD.

Objectives: The aim of the study was to investigate the association between exposure to airborne pollutants and the risk of COPD exacerbations in 3 the largest urban agglomerations in Poland: Warsaw, Kraków, and Tricity.

Inflammation Related to Obesity in the Etiopathogenesis of Gastroenteropancreatic Neuroendocrine Neoplasms.

Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are rare neoplasms, which, due to their heterogeneous nature, non-specific symptoms, and lack of specific tumor markers pose many diagnostic and clinical challenges. In recent years, the effectiveness of GEP-NEN diagnosis has increased, which is probably associated with the greater availability of diagnostic tests and the cooperation of many experienced specialists in various scientific disciplines. In addition to the possible genetic etiology, the cause of GEP-NET development is not fully understood.

Differences in carotid artery atherosclerosis between men and women in the early phase after ischemic event.

Objectives: There is little data about sex differences in carotid atherosclerosis in the early phase after an ischemic event. The aim of this study was to examine the carotid artery atherosclerosis differences between men and women in early phase after TIA or stroke.

Methods: Consecutive patients with recent ischemic event, admitted during the first week after symptom onset were examined with ultrasound.

Clonal distribution of bone sialoprotein-binding protein gene among Staphylococcus aureus isolates associated with bloodstream infections.

Staphylococcus aureus is a leading cause of bloodstream infections (BSI) and diseases that may be caused by hematogenous spread. The staphylococcal adhesin, for which the association with the infections emerging as a complication of septicemia has been well documented, is a bone sialoprotein-binding protein (Bbp). The aim of the study was to assess the prevalence of a bbp gene in S.
