Transient haemoptysis after taking sildenafil.

We report a case of a man in his 70s who developed haemoptysis 3 days after commencing sildenafil. Before postulating a potential connection between sildenafil use and haemoptysis, it is important to rule out potential other causative factors and comorbidities. The patient suffers from multiple medical conditions and takes various medications.

Delivering medical leadership training through the Healthcare Leadership Academy: a four year analysis.

Background: Formal leadership training is typically targeted at senior health professionals. The Healthcare Leadership Academy (HLA) was formed in 2016 to provide a leadership programme for students and early-career health professionals. This study analyses the effectiveness of the HLA scholarship programme as an intervention for improving interest in and preparing scholars for future leadership roles.

Amygdalar activity measured using FDG-PET/CT at head and neck cancer staging independently predicts survival.

Importance: The mechanisms underlying the association between chronic stress and higher mortality among individuals with cancer remain incompletely understood.

Objective: To test the hypotheses that among individuals with active head and neck cancer, that higher stress-associated neural activity (ie. metabolic amygdalar activity [AmygA]) at cancer staging associates with survival.

The non-substitutable characteristic of scientific journals has facilitated an environment of market concentration. Acquisition of journals on a capabilities-based approach has seen market concentration increase in favor of a small group of dominant publishers.
