Structural features of distributive trades and their impact on prices in the euro area

The distributive trades sector, which is primarily accounted for by wholesale and retail trade, is not only economically important in its own right, but also relevant to monetary policy. Ultimately, it is retailers who set the actual prices of most consumer goods. They are the main interface between producers of consumer goods and consumers, with around half of private consumption accounted for by retail trade. The “value added” of this intermediation service can be substantial, as this accounts for, on average, about 25% of consumer prices. The purpose of this report is to analyse the structural features of the distributive trades sector and the developments within it, as well as how these may influence prices and price dynamics. This report contributes to a better understanding of the impact of the structural features of the distributive trades sector on prices and price-setting behaviour, thereby improving on previous research in this area. From a policy perspective, it highlights the importance of structural reforms that help enhance competition in this sector. This report uses a wide range of data sources – some of which are unique – to study an area that has been under-investigated, especially at the European level. There is, however, ample room for further research in this direction. JEL Classification: E58, F41competition, distributive trades, monetary policy, prices, retail trades

European Society of Cardiology guidance for the diagnosis and management of cardiovascular disease during the COVID-19 pandemic: part 1-epidemiology, pathophysiology, and diagnosis.

peer reviewed[en] AIMS: Since its emergence in early 2020, the novel severe acute respiratory syndrome coronavirus 2 causing coronavirus disease 2019 (COVID-19) has reached pandemic levels, and there have been repeated outbreaks across the globe. The aim of this two-part series is to provide practical knowledge and guidance to aid clinicians in the diagnosis and management of cardiovascular disease (CVD) in association with COVID-19. METHODS AND RESULTS: A narrative literature review of the available evidence has been performed, and the resulting information has been organized into two parts. The first, reported here, focuses on the epidemiology, pathophysiology, and diagnosis of cardiovascular (CV) conditions that may be manifest in patients with COVID-19. The second part, which will follow in a later edition of the journal, addresses the topics of care pathways, treatment, and follow-up of CV conditions in patients with COVID-19. CONCLUSION: This comprehensive review is not a formal guideline but rather a document that provides a summary of current knowledge and guidance to practicing clinicians managing patients with CVD and COVID-19. The recommendations are mainly the result of observations and personal experience from healthcare providers. Therefore, the information provided here may be subject to change with increasing knowledge, evidence from prospective studies, and changes in the pandemic. Likewise, the guidance provided in the document should not interfere with recommendations provided by local and national healthcare authorities

Assessing the Current Role of Platelet Function Testing

In vitro platelet function tests are commonly applied in research and offer justification for using antiplatelet therapy. However, studies assessing the ability of standardized platelet function tests to predict patients' clinical response to aspirin or clopidogrel have generated contradictory results. At this time, there is no standardized definition for resistance to antiplatelet therapy, and the appropriate treatment of patients who are hyporesponsive to these agents is not known. Although such tests have a role in research, their place in guiding therapy remains to be established, and prospective trials are urgently needed. The ideal platelet function test for clinical practice would be rapid, easy-to-use, inexpensive, and reliable.

Measurements on hydrophobic and hydrophilic surfaces using a porous gamma alumina nanoparticle aggregate mounted on Atomic Force Microscopy cantilevers

Atomic Force Microscopy (AFM) measurements are extensively used for a detailed understanding ofmolecular and surface forces. In this study, we present a technique for measuring such forces, using an AFM cantilever attached with a porous gamma alumina nanoparticle aggregate. The modified cantilever was used to measure the forces of interaction of the aggregate with hydrophilic and hydrophobic surfaces. A strong force of attraction was observed between the aggregate and hydrophilic surfaces when the aggregate was kept dry. However, the force of interaction on the aggregate in wet form (water filled in pores) was larger when the adjoining surface had hydrophobic characteristics. The results presented in this study show the versatility of the current technique and indicate its usefulness in directly characterizing hydrophilic/ hydrophobic properties of nano-scale surfaces and patterns

Ticagrelor vs. clopidogrel in patients with acute coronary syndromes and diabetes: a substudy from the PLATelet inhibition and patient Outcomes (PLATO) trial

Patients with diabetes mellitus (DM) have high platelet reactivity and are at increased risk of ischaemic events and bleeding post-acute coronary syndromes (ACS). In the PLATelet inhibition and patient Outcomes (PLATO) trial, ticagrelor reduced the primary composite endpoint of cardiovascular death, myocardial infarction, or stroke, but with similar rates of major bleeding compared with clopidogrel. We aimed to investigate the outcome with ticagrelor vs. clopidogrel in patients with DM or poor glycaemic control. We analysed patients with pre-existing DM (n = 4662), including 1036 patients on insulin, those without DM (n = 13 951), and subgroups based on admission levels of haemoglobin A1c (HbA1c; n = 15 150). In patients with DM, the reduction in the primary composite endpoint (HR: 0.88, 95% CI: 0.76-1.03), all-cause mortality (HR: 0.82, 95% CI: 0.66-1.01), and stent thrombosis (HR: 0.65, 95% CI: 0.36-1.17) with no increase in major bleeding (HR: 0.95, 95% CI: 0.81-1.12) with ticagrelor was consistent with the overall cohort and without significant diabetes status-by-treatment interactions. There was no heterogeneity between patients with or without ongoing insulin treatment. Ticagrelor reduced the primary endpoint, all-cause mortality, and stent thrombosis in patients with HbA1c above the median (HR: 0.80, 95% CI: 0.70-0.91; HR: 0.78, 95% CI: 0.65-0.93; and HR: 0.62, 95% CI: 0.39-1.00, respectively) with similar bleeding rates (HR: 0.98, 95% CI: 0.86-1.12). Ticagrelor, when compared with clopidogrel, reduced ischaemic events in ACS patients irrespective of diabetic status and glycaemic control, without an increase in major bleeding events

Heart Rate Variability in Men with Erectile dysfunction

Purpose The objective of this study is to investigate alteration of autonomic nervous system (ANS) activity in patients suffering from erectile dysfunction (ED) by comparing parameters of heart rate variability (HRV) between men with ED and healthy subjects. Methods A retrospective review was performed on 40 ED patients (mean age, 46.0±8.49 years) without any disease and 180 healthy control people (mean age, 44.4±7.83 years) without ED in our institution from June 2008 to July 2010. And electrocardiographic signals were obtained to measure HRV parameters for both patients and controls in a resting state. Results For the time domain analysis, square root of the mean differences between successive RR intervals (RMSSD) representing parasympathetic activity was lower in patients than controls although P-value was not statistically significant (P=0.060). For the frequency domain analysis, high frequency (HF) representing parasympathetic activity was lower in patients than controls (P=0.232) and low frequency (LF) representing mainly sympathetic activity was higher in patients than controls (P=0.416). Lastly, LF/HF ratio reflecting sympathetic/parasympathetic activity ratio was statistically higher in patients than controls (P=0.027). Conclusions Patients with ED exhibited different HRV parameters compared with normal controls. This suggests that the patients with ED may have some kind of imbalance in the ANS and it may be possible that general imbalance of the ANS is one of the causes of ED. Thus, HRV analysis may give valuable diagnostic information and serve as a rapid screening tool to evaluate altered ANS activity in patients with ED

Increasing Implementation and Delivery of Pulmonary Rehabilitation: Key Messages from the New ATS/ERS Policy Statement.

In December 2015 the Official ATS/ERS Policy Statement on Enhancing Implementation, Use and Delivery of Pulmonary Rehabilitation (PR) was published [1] with the aim of providing policy recommendations to increase implementation and delivery of PR worldwide. Major areas addressed included increasing healthcare professional, payer and patient awareness and knowledge of PR, increasing patient access to PR, improving quality of PR programs and future research directions to advance evidence-based policy in PR. This ATS/ERS document was developed via an iterative consensus process by an ad hoc Task Force on Policy in PR comprised of experts from the ATS Pulmonary Rehabilitation Assembly, the ERS Rehabilitation and Chronic Care Group, the ATS and ERS Documents Development and Implementation Committees, representatives from the European Lung Foundation (ELF) and primary care representatives from the USA and Europe between May 2013 and January 2015. Input was obtained via informal surveys from patients, patient advocacy groups, (including the ATS Public Advisory Roundtable and ELF), insurance payers, as well as primary and pulmonary specialty healthcare providers. The Policy Statement was approved by the Board of Directors of the ATS and the Science Council and Executive Committee of the ERS. This editorial provides ERJ readers with a concise reflection on the key issues addressed and summarizes the policy recommendations made in the ATS/ERS Policy Statement[1] to enhance implementation, use and delivery of PR

A proposed scoring system for assessing the severity of actinic keratosis on the head: actinic keratosis area and severity index

Background: Actinic keratosis (AK) severity is currently evaluated by subjective assessment of patients. Objectives: To develop and perform an initial pilot validation of a new easy-to-use quantitative tool for assessing AK severity on the head. Methods: The actinic keratosis area and severity index (AKASI) for the head was developed based on a review of other severity scoring systems in dermatology, in particular the psoriasis area and severity index (PASI). Initial validation was performed by 13 physicians assessing AK severity in 18 AK patients and two controls using a physician global assessment (PGA) and AKASI. To determine an AKASI score, the head was divided into four regions (scalp, forehead, left/right cheek ear, chin and nose). In each region, the percentage of the area affected by AKs was estimated, and the severities of three clinical signs of AK were assessed: distribution, erythema and thickness. Results: There was a strong correlation between AKASI and PGA scores (Pearson correlation coefficient: 0.86). AKASI was able to discriminate between different PGA categories: mean (SD) AKASI increased from 2.88 (1.18) for ‘light’ to 5.33 (1.48) for ‘moderate’, 8.28 (1.89) for ‘severe’, and 8.73 (3.03) for ‘very severe’ PGA classification. The coefficient of variation for AKASI scores was low and relatively constant across all PGA categories. Conclusions: Actinic keratosis area and severity index is proposed as a new quantitative tool for assessing AK severity on the head. It may be useful in the future evaluation of new AK treatments in clinical studies and the management of AK in daily practice
