Among patients with unstable angina or myocardial infarction without ST-segment elevation, prasugrel did not significantly reduce the frequency of the primary end point, as compared with clopidogrel, and similar risks of bleeding were observed.

: Hydralazine, an arterial vasodilator, is a widely used medication for the management of hypertension and heart failure, especially for patients who cannot tolerate the use of ACEIs or ARBs. It is generally well tolerated and has safe profile in pregnancy. However, hydralazine can induce immune mediated side effects, such as hydralazine-induced lupus and less commonly hydralazine-induced ANCA vasculitis. 2 The latter most commonly affects the kidneys with or without other organ involvement. There are several cases reported in the literature of hydralazine-induced ANCA associated vasculitis (AAV) that have pulmonary manifestations, also known as hydralazine-induced pulmonary-renal syndrome (PRS), a condition with high risk of mortality. We are reporting a case of Hydralazine-induced ANCA associated glomerulonephritis with severe diffuse alveolar hemorrhage (DAH). In addition, we will review the current literature and discuss the importance of prompt diagnosis and early management to decrease mortality and morbidity associated with this serious condition.

Cardiac manifestations of COVID-19 include myocarditis, demand ischemia, myocardial infarction and arrhythmias with prothrombotic state being a major underlying pathogenetic mechanism. In this report we present a case of a 57-year-old, otherwise healthy, woman who presented with chest pain and nausea and was found to have an inferior wall ST-elevation myocardial infarction (STEMI) in the setting of an active COVID-19 infection. Angiography revealed tortuous coronary arteries with a 100% right coronary artery occlusion with high thrombus burden and normal left coronary system. In light of the available literature regarding the pro-thrombotic effects of this novel corona virus, we continued full dose anticoagulation with Enoxaparin after the cardiac catheterization and transitioned to rivaroxaban and we also continued the patient on dual antiplatelet therapy prior to discharge.

The study was undertaken to investigate the effects of pacing on aspects of performance at an assembly task and on the operators' responses related to work behaviour, perceived workload and perceived stress. A particular objective of the study was to investigate whether physical and cognitive demands may interact in their influences on these effects. An assembly task was simulated in the laboratory and the level of pacing imposed, work height and memory load within the task were all varied. The results showed that the type of pacing commonly imposed (as is common with a lean manufacturing Takt time system in industry) can significantly affect both performance and perceived workload and stress. Physical demands (through work height affecting posture) and mental demand (through memory load) were also found to have significant effects, as would be expected from the many studies of these in the literature. More importantly, some interactions were found between pacing and work height in their effects on quality of assembly and the operator's own rating of performance, and between work height and memory load in their effects on errors. These findings will need to be taken into account by companies when implementing Takt time systems.
