Exposure to PM2.5 and PM10 pollution and the risk of respiratory diseases in upper Silesia inhabitants

Background: Multiple studies confirm that PM2.5 and PM10 can affect lung growth and development in children and adolescents, the number of medical visits, and hospital emergency admissions due to asthma, respiratory symptoms, and upper and lower respiratory tract disorders. Objective: The objective of this study was the measurement-based assessment for determining whether the concentrations of PM10 and PM2.5 are within admissible limits or exceeded in the Upper Silesia urban area (Silesia province) and to examine the relationship between PM concentrations and the number of admissions in Primary Health Care due to respiratory diseases like asthma and chronic bronchitis for children, adolescents and adults. Material and methods: The data provided by the Voivodship Inspectorate for Environmental Protection in Katowice, National Health Fund - Silesian Department, and the District Sanitary-Epidemiological Station in Katowice for the period 2012-2017 was used in the statistical analysis. Results: The increase in the number of excessive levels of average daily PM10 concentration was observed in almost all measurement stations, both for the acceptable level, information, and alarm level. The increase in average annual PM2.5 concentrations was also observed. The results showed an increased prevalence of respiratory diseases (ICD-Diagnosis Code 10-CM: J017, J030, J034, J038, J040) during the study period in 14 of 20 cities of Silesia province, consistently higher for children than adults. Conclusions: In Silesia province, the air quality is poor and has deteriorated over the last few years. Exposure to ambient PM2.5 and PM10 was significantly associated with the development of respiratory tract diseases in children and adults

Prolonged antithrombotic therapy in patients after acute coronary syndrome: A critical appraisal of current European Society of Cardiology guidelines

The increased risk of non-cardiovascular death in patients receiving clopidogrel or prasugrel in comparison with the placebo group in the Dual Antiplatelet Therapy (DAPT) trial in contrast to the decreased risk of cardiovascular death and all-cause death seen in patients treated with low-dose ticagrelor in the EU label population of the PEGASUS-TIMI 54 trial, resulted in inclusion in the 2020 ESC NSTE-ACS guidelines the recommendation for use of clopidogrel or prasugrel only if the patient is not eligible for treatment with ticagrelor.The prevalence of the primary outcome composed of cardiovascular death, stroke, or myocardial infarction was lower in the low-dose rivaroxaban and acetylsalicylic acid (ASA) group than in the ASA-alone group in the COMPASS trial. Moreover, all-cause mortality and cardiovascular mortality rates were lower in the rivaroxaban-plus-ASA group.Comparison of the PEGASUS-TIMI 54 and COMPASS trial patient characteristics clearly shows that each of these treatment strategies should be addressed at different groups of patients. A greater benefit in post-acute coronary syndrome (ACS) patients with a high risk of ischemic events and without high bleeding risk may be expected with ASA and ticagrelor 60 mg b.i.d. when the therapy is continued without interruption or with short interruption only after ACS. On the other hand, ASA and rivaroxaban 2.5 mg b.i.d. seems to be a better option when indications for dual antithrombotic therapy (DATT) appear after a longer time from ACS (more than 2 years) and/or from cessation of DAPT (more than 1 year) and in patients with multiple vascular bed atherosclerosis. Thus, both options of DATTs complement each other rather than compete, as can be presumed from the recommendations. However, a direct comparison between these strategies should be tested in future clinical trials

MCDM Approach to the Excise Goods Daily Delivery Scheduling Problem. Case Study: Alcohol Products Delivery Scheduling under Intra-community Trade Regulations

AbstractThis paper presents a multiple criteria decision making approach for solving the excise goods daily delivery scheduling problem. The presented procedure enables to determine the schedule of deliveries from many suppliers to one consignee. The algorithm combines heuristic approach and the Light Beam Search method. The minimal dispersion of unloadings in the consignee's warehouse as well as minimal dispersions of loadings in suppliers’ warehouses are the criteria used for selecting the most satisfactory delivery schedule. The paper presents also an example of application of the proposed algorithm in the real problem concerning alcohol products delivery scheduling under Intra-Community Trade regulations
