Introduction: This study aimed to compare the long-term outcomes in a propensity matched population receiving either minimally invasive direct coronary artery bypass (MIDCAB) using left internal thoracic artery (LITA) to the left anterior descending artery (LAD) or percutaneous coronary intervention using second generation everolismus-eluting stents (DES-PCI) in patients treated for isolated proximal LAD stenosis.

Methods: Between January 2012 and December 2017, 421 patients with a nonemergency status undergoing primary isolated proximal LAD revascularization were retrospectively analyzed and were divided into two groups: 111 patients receiving MIDCAB LITA to LAD and 310 patients receiving DES-PCI. Propensity score matching selected 111 pairs and both groups were comparable for all baseline characteristics and well balanced.

This study examines the Waste Kuznets Curve (WKC) hypothesis by integrating it with the Tapio decoupling model to explore the relationship between economic development and e-waste imports in 45 emerging economies from 2002 to 2022. The empirical results show that (1) the relationship between economic growth and e-waste imports exhibits an inverted U-shaped curve, with decoupling achieved when GDP per capita exceeds the WKC turning point of $10,755.23; (2) Emerging economies are categorized into six quadrants based on their e-waste decoupling status: high-income non-decoupling, low-income non-decoupling, low-income relative decoupling, high-income relative decoupling, low-income absolute decoupling, and high-income absolute decoupling; (3) Most emerging economies remain in low-income non-decoupling state, with only a few countries like China and Poland achieving high-income absolute decoupling.

Transvenous extraction of the leads in children is associated with a higher risk of serious complications, that is why it is reluctantly performed. Unfortunately, this conservative approach has been associated with secondary complications (tricuspid valve dysfunction and bilateral venous obstruction), adverse events during lead removal procedure and recanalization and stenting of chest veins. We present a case of a 27-year-old female with a pacemaker and insertion of two new leads on the opposite side of the chest leaving the old ones in place.

Assessing actual and potential impacts of non-native species is necessary for prioritising their management. Traditional assessments often occur at the species level, potentially overlooking differences among populations. The recently developed Dispersal-Origin-Status-Impact (DOSI) assessment scheme addresses this by treating biological invasions as population-level phenomena, incorporating the complexities affecting populations of non-native species.
